A date-time object is supposed to store the information about the date, time, timezone etc., not about the formatting. You can format a date-time object into a String
with the pattern of your choice using date-time formatting API.
java.time.format
e.g. java.time.format.DateTimeFormatter
, java.time.format.DateTimeFormatterBuilder
etc.java.text
e.g. java.text.SimpleDateFormat
, java.text.DateFormat
etc.Demo using modern API:
import java.time.LocalDate;
import java.time.Month;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Locale;
public class Main {
public static void main(String[] args) {
ZonedDateTime zdt = ZonedDateTime.of(LocalDate.of(2012, Month.DECEMBER, 1).atStartOfDay(),
ZoneId.of("Europe/London"));
// Default format returned by Date#toString
System.out.println(zdt);
// Custom format
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd", Locale.ENGLISH);
String formattedDate = dtf.format(zdt);
System.out.println(formattedDate);
}
}
Output:
2012-12-01T00:00Z[Europe/London]
2012-12-01
Learn about the modern date-time API from Trail: Date Time.
Demo using legacy API:
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import java.util.TimeZone;
public class Main {
public static void main(String[] args) {
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
calendar.setTimeInMillis(0);
calendar.set(Calendar.YEAR, 2012);
calendar.set(Calendar.MONTH, 11);
calendar.set(Calendar.DAY_OF_MONTH, 1);
Date date = calendar.getTime();
// Default format returned by Date#toString
System.out.println(date);
// Custom format
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
String formattedDate = sdf.format(date);
System.out.println(formattedDate);
}
}
Output:
Sat Dec 01 00:00:00 GMT 2012
2012-12-01
Some more important points:
java.util.Date
object is not a real date-time object like the modern date-time types; rather, it represents the milliseconds from the Epoch of January 1, 1970
. When you print an object of java.util.Date
, its toString
method returns the date-time calculated from this milliseconds value. Since java.util.Date
does not have timezone information, it applies the timezone of your JVM and displays the same. If you need to print the date-time in a different timezone, you will need to set the timezone to SimpleDateFomrat
and obtain the formatted string from it.java.util
and their formatting API, SimpleDateFormat
are outdated and error-prone. It is recommended to stop using them completely and switch to the modern date-time API.
I had installed anaconda via the system installer on OS X in the past, which created a ~/.conda/environments.txt
owned by root. Conda could not modify this file, hence the error.
To fix this issue, I changed the ownership of that directory and file to my username:
sudo chown -R $USER ~/.conda
use below method for setting padding dynamically
setPadding(int left, int top, int right, int bottom)
Example :
view.setPadding(2,2,2,2);
Make sure you don't have any undefined classpath variables (like M2_REPO).
This is a good way to do it:
<?php
if (!(isset($_SERVER['HTTPS']) && ($_SERVER['HTTPS'] == 'on' ||
$_SERVER['HTTPS'] == 1) ||
isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &&
$_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'))
{
$redirect = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $redirect);
exit();
}
?>
For outputing String
as text/plain
use:
@RequestMapping(value="/foo", method=RequestMethod.GET, produces="text/plain")
@ResponseBody
public String foo() {
return "bar";
}
On my machine this only works in bin/idea.vmoptions
, adding the setting in ~/Library/Preferences/IntelliJIdea12/idea.vmoptions
causes the IDEA to hang during startup.
You should add fstream::out to open method like this:
file.open("test.txt",fstream::out);
More information about fstream flags, check out this link: http://www.cplusplus.com/reference/fstream/fstream/open/
I was also getting the same error --> "[PDOException] could not find driver "
I realized that the php was pointing to /usr/bin/php instead of the lampp /opt/lampp/bin/php so i simply created and alias
alias php="/opt/lampp/bin/php"
also had to make update to the .env file to ensure the database access credentials were updated.
And guess what, it Worked!
In a linked question, there's some Objective-C code to get the mime type for a file URL. I've created a Swift extension based on that Objective-C code to get the mime type:
import Foundation
import MobileCoreServices
extension URL {
var mimeType: String? {
guard self.pathExtension.count != 0 else {
return nil
}
let pathExtension = self.pathExtension as CFString
if let preferredIdentifier = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension, nil) {
guard let mimeType = UTTypeCopyPreferredTagWithClass(preferredIdentifier.takeRetainedValue(), kUTTagClassMIMEType) else {
return nil
}
return mimeType.takeRetainedValue() as String
}
return nil
}
}
I always keep coming here to check for int/hex alpha value. So, end up creating a simple method in my java utils class. This method will convert the percentage to hex value and append to the color code string value.
public static String setColorAlpha(int percentage, String colorCode){
double decValue = ((double)percentage / 100) * 255;
String rawHexColor = colorCode.replace("#","");
StringBuilder str = new StringBuilder(rawHexColor);
if(Integer.toHexString((int)decValue).length() == 1)
str.insert(0, "#0" + Integer.toHexString((int)decValue));
else
str.insert(0, "#" + Integer.toHexString((int)decValue));
return str.toString();
}
So, Utils.setColorAlpha(30, "#000000")
will give you #4c000000
<button my-directive="push">Push to Go</button>
app.directive("myDirective", function() {
return {
restrict : "A",
link: function(scope, elm, attrs) {
elm.bind('click', function(event) {
alert("You pressed button: " + event.target.getAttribute('my-directive'));
});
}
};
});
here is what I did
I'm using directive as html attribute and I passed parameter as following in my HTML file. my-directive="push"
And from the directive I retrieved it from the Mouse-click event object. event.target.getAttribute('my-directive')
.
Declare variable to assign value returned from setInterval(...) and pass the assigned variable to clearInterval();
e.g.
var timer, intervalInSec = 2;
timer = setInterval(func, intervalInSec*1000, 30 ); // third parameter is argument to called function 'func'
function func(param){
console.log(param);
}
// Anywhere you've access to timer declared above call clearInterval
$('.htmlelement').click( function(){ // any event you want
clearInterval(timer);// Stops or does the work
});
You can change the port number:
Open the server tab in eclipse -> right click open click on open---->you can change the port number.
Run the application with http://localhost:8080/Applicationname
it will give output and also check http://localhost:8080/Applicationname/index.jsp
At least in version 2.2.3 that I'm using, you must use autoClose
instead of autoclose
. Letter case matters.
In Kotlin I did the following to just show the icon:
supportActionBar?.setDisplayShowHomeEnabled(true)
supportActionBar?.setIcon(R.drawable.ic_icon_small)

However, it didn't work for me first try. I found this tip: run "httpd -t" in Terminao to check the syntax of your config files. Turns out using copy & paste from the tutorial introduced some strange characters. After fixing this, it worked great. There are some links from the guide for adding MySQL as well.
This worked much better for me than MAMP. With MAMP, I was having delays of about 20 seconds or so before changes to the .php file would be reflected in the browser when you refresh, even if you cleared the cache, history, cookies, etc.
This problem was resolved in MAMP PRO, but MAMP PRO had a new issue of its own: the .php files would be downloaded instead of being rendered as a page in the browser! I contacted support and they didn't know what was going on.
The built-in Apache server didn't have any of these issues. Definitely the way to go. The guide below is almost identical to the one above, but it has user comments that are helpful:
http://osxdaily.com/2012/09/02/start-apache-web-server-mac-os-x/#comment-572991
You can check the socket.connected
property:
var socket = io.connect();
console.log('check 1', socket.connected);
socket.on('connect', function() {
console.log('check 2', socket.connected);
});
It's updated dynamically, if the connection is lost it'll be set to false
until the client picks up the connection again. So easy to check for with setInterval
or something like that.
Another solution would be to catch disconnect
events and track the status yourself.

what your wanted.An abstract class is a type of class that can only be used as a base class for another class; such thus cannot be instantiated. To make a class abstract, the keyword abstract is used. Abstract classes may have one or more abstract methods that only have a header line (no method body). The method header line ends with a semicolon (;). Any class that is derived from the base class can define the method body in a way that is consistent with the header line using all the designated parameters and returning the correct data type (if the return type is not void). An abstract method acts as a place holder; all derived classes are expected to override and complete the method.
Example in Java
abstract public class Shape
{
double area;
public abstract double getArea();
}
Before answering your question:
If you do not have a Person
class, first you must consider whether you want to create a Person
class. Do you plan to reuse the concept of a Person
very often? If so, you should create a Person
class. (You have access to this data in the form of a passed-in variable and you don't care about being messy and sloppy.)
To answer your question:
You have access to their birthyear, so in that case you likely have a Person
class with a someperson.birthdate
field. In that case, you have to ask yourself, is someperson.age
a value that is reusable?
The answer is yes. We often care about age more than the birthdate, so if the birthdate is a field, age should definitely be a derived field. (A case where we would not do this: if we were calculating values like someperson.chanceIsFemale
or someperson.positionToDisplayInGrid
or other irrelevant values, we would not extend the Person
class; you just ask yourself, "Would another program care about the fields I am thinking of extending the class with?" The answer to that question will determine if you extend the original class, or make a function (or your own class like PersonAnalysisData
or something).)

Just because @MartinCapodici 's comment is awesome I write here as an answer to give visibility.
All clockwise:
For those coming here and are using Java config you can set the Bean to lazy-init using annotations like this:
In the configuration class:
@Configuration
// @Lazy - For all Beans to load lazily
public class AppConf {
@Bean
@Lazy
public Demo demo() {
return new Demo();
}
}
For component scanning and auto-wiring:
@Component
@Lazy
public class Demo {
....
....
}
@Component
public class B {
@Autowired
@Lazy // If this is not here, Demo will still get eagerly instantiated to satisfy this request.
private Demo demo;
.......
}
You can do a form.serializeArray(), then add name-value pairs before posting:
var form = $(this).closest('form');
form = form.serializeArray();
form = form.concat([
{name: "customer_id", value: window.username},
{name: "post_action", value: "Update Information"}
]);
$.post('/change-user-details', form, function(d) {
if (d.error) {
alert("There was a problem updating your user details")
}
});
If the file is only numerical values separated by tabs, try using the csv library: http://docs.python.org/library/csv.html (you can set the delimiter to '\t')
If you have a textual file in which every line represents a row in a matrix and has integers separated by spaces\tabs, wrapped by a 'arrayname = [...]' syntax, you should do something like:
import re
f = open("your-filename", 'rb')
result_matrix = []
for line in f.readlines():
match = re.match(r'\s*\w+\s+\=\s+\[(.*?)\]\s*', line)
if match is None:
pass # line syntax is wrong - ignore the line
values_as_strings = match.group(1).split()
result_matrix.append(map(int, values_as_strings))
You can generate the WS proxy classes using WSCF (Web Services Contract First) tool from thinktecture.com. So essentially, YOU CAN create webservices from wsdl's. Creating the asmx's, maybe not, but that's the easy bit isn't it? This tool integrates brilliantly into VS2005-8 (new version for 2010/WCF called WSCF-blue). I've used it loads and always found it to be really good.
For a hash function it's not only important to minimize colisions generally but to make it impossible to stay with the same hash while chaning a few bytes.
Say you have an equation:
(x + y*z) % key = x
with 0<x<key
and 0<z<key
.
If key is a primenumber n*y=key is true for every n in N and false for every other number.
An example where key isn't a prime example: x=1, z=2 and key=8 Because key/z=4 is still a natural number, 4 becomes a solution for our equation and in this case (n/2)*y = key is true for every n in N. The amount of solutions for the equation have practially doubled because 8 isn't a prime.
If our attacker already knows that 8 is possible solution for the equation he can change the file from producing 8 to 4 and still gets the same hash.
In addition to what Andrew said, it is worth noting that:
The distinction between a language, a runtime, and a library is more strict in .NET/C# than for example in C++, where the language specification also includes some basic library functions. The C# specification says only a very little about the environment (basically, that it should contain some types such as int
, but that's more or less all).
Here is the easiest answer:
in your view only just add:
@Html.DropDownListFor(model => model.tipo, new SelectList(new[]{"Exemplo1",
"Exemplo2", "Exemplo3"}))
OR in your controller add:
var exemploList= new SelectList(new[] { "Exemplo1:", "Exemplo2", "Exemplo3" });
ViewBag.ExemploList = exemploList;
and your view just add:
@Html.DropDownListFor(model => model.tipo, (SelectList)ViewBag.ExemploList )

Even though SQLMenace's answer has been accepted, there is one important SET
option you should be aware of
DATENAME will return correct date name but not the same DATEPART value if the first day of week has been changed as illustrated below.
declare @DefaultDateFirst int
set @DefaultDateFirst = @@datefirst
--; 7 First day of week is "Sunday" by default
select [@DefaultDateFirst] = @DefaultDateFirst
set datefirst @DefaultDateFirst
select datename(dw,getdate()) -- Saturday
select datepart(dw,getdate()) -- 7
--; Set the first day of week to * TUESDAY *
--; (some people start their week on Tuesdays...)
set datefirst 2
select datename(dw,getdate()) -- Saturday
--; Returns 5 because Saturday is the 5th day since Tuesday.
--; Tue 1, Wed 2, Th 3, Fri 4, Sat 5
select datepart(dw,getdate()) -- 5 <-- It's not 7!
set datefirst @DefaultDateFirst
I ran into this today and wanted to share my fix, since this one is simply overlooked and easy to fix.
We manage our own rDNS and recently redid our server naming scheme. As part of that, we should have updated our rDNS and forgot to do this.
A ping turned up the correct hostname, but a ping -a returned the wrong hostname.
Easy fix: change the rDNS, do an ipconfig /flushdns, wait 30 seconds (just something I do), do another ping -a , see it resolving the correct hostname, connect ... profit.
Based on usage should use this get
method.

you could use something like
<select ng-model="myselect">
<option ng-repeat="o in options" ng-selected="{{o==myselect}}" value="{{o}}">
{{o}}
</option>
</select>
using ng-selected you preselect the option in case myselect was prefilled.
I prefer this method over ng-options anyway, as ng-options only works with arrays. ng-repeat also works with json-like objects.
Yes, it is not required and is usually omitted. It might be required for accessing variables after they have been overridden in the scope though:
Person::Person() {
int age;
this->age = 1;
}
Also, this:
Person::Person(int _age) {
age = _age;
}
It is pretty bad style; if you need an initializer with the same name use this notation:
Person::Person(int age) : age(age) {}

Backgrounding ComponentCallbacks2 — Looking at the documentation is not 100% clear on how you would use this. However, take a closer look and you will noticed the onTrimMemory method passes in a flag. These flags are typically to do with the memory availability but the one we care about is TRIM_MEMORY_UI_HIDDEN. By checking if the UI is hidden we can potentially make an assumption that the app is now in the background. Not exactly obvious but it should work.
Foregrounding ActivityLifecycleCallbacks — We can use this to detect foreground by overriding onActivityResumed and keeping track of the current application state (Foreground/Background).
Create our interface that will be implemented by a custom Application class
interface LifecycleDelegate {
fun onAppBackgrounded()
fun onAppForegrounded()
}
Create a class that is going to implement the ActivityLifecycleCallbacks and ComponentCallbacks2 and override onActivityResumed and onTrimMemory methods
// Take an instance of our lifecycleHandler as a constructor parameter
class AppLifecycleHandler(private val lifecycleDelegate: LifecycleDelegate)
: Application.ActivityLifecycleCallbacks, ComponentCallbacks2 // <-- Implement these
{
private var appInForeground = false
// Override from Application.ActivityLifecycleCallbacks
override fun onActivityResumed(p0: Activity?) {
if (!appInForeground) {
appInForeground = true
lifecycleDelegate.onAppForegrounded()
}
}
// Override from ComponentCallbacks2
override fun onTrimMemory(level: Int) {
if (level == ComponentCallbacks2.TRIM_MEMORY_UI_HIDDEN) {
// lifecycleDelegate instance was passed in on the constructor
lifecycleDelegate.onAppBackgrounded()
}
}
}
Now all we need to do is have our custom Application class implement our LifecycleDelegate interface and register.
class App : Application(), LifeCycleDelegate {
override fun onCreate() {
super.onCreate()
val lifeCycleHandler = AppLifecycleHandler(this)
registerLifecycleHandler(lifeCycleHandler)
}
override fun onAppBackgrounded() {
Log.d("Awww", "App in background")
}
override fun onAppForegrounded() {
Log.d("Yeeey", "App in foreground")
}
private fun registerLifecycleHandler(lifeCycleHandler: AppLifecycleHandler) {
registerActivityLifecycleCallbacks(lifeCycleHandler)
registerComponentCallbacks(lifeCycleHandler)
}
}
In Manifest set the CustomApplicationClass
<application
android:name=".App"
def my_sort(lst):
a = []
for i in range(len(lst)):
a.append(min(lst))
lst.remove(min(lst))
return a
def my_revers_sort(lst):#in revers!!!!!
a = []
for i in range(len(lst)):
a.append(max(lst))
lst.remove(max(lst))
return a
Before you make your final decision, be aware that the JSON format is not safe for associative arrays - json_decode()
will return them as objects instead:
$config = array(
'Frodo' => 'hobbit',
'Gimli' => 'dwarf',
'Gandalf' => 'wizard',
);
print_r($config);
print_r(json_decode(json_encode($config)));
Output is:
Array
(
[Frodo] => hobbit
[Gimli] => dwarf
[Gandalf] => wizard
)
stdClass Object
(
[Frodo] => hobbit
[Gimli] => dwarf
[Gandalf] => wizard
)
For large datasets, it is memory efficient to read only selected rows via the skiprows
parameter.
Example
pred = lambda x: x not in [1, 3]
pd.read_csv("data.csv", skiprows=pred, index_col=0, names=...)
This will now return a DataFrame from a file that skips all rows except 1 and 3.
Details
From the docs:
skiprows
: list-like or integer or callable, defaultNone
...
If callable, the callable function will be evaluated against the row indices, returning True if the row should be skipped and False otherwise. An example of a valid callable argument would be
lambda x: x in [0, 2]
This feature works in version pandas 0.20.0+. See also the corresponding issue and a related post.
I had the same issue. And in my case the fix was pretty simple. The trick is to simply add the ".exe" to your compilers path. So, instead of :
SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc)
It should be
SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc.exe)
The same applies for g++.
For me it's:
Click Build tab ---> Clean Project

If you want to save your numpy array (e.g. your_array = np.array([[1,2],[3,4]])
) to one cell, you could convert it first with your_array.tolist()
.
Then save it the normal way to one cell, with delimiter=';'
and the cell in the csv-file will look like this [[1, 2], [2, 4]]
Then you could restore your array like this:
your_array = np.array(ast.literal_eval(cell_string))
Spent a while on this issue, and the PATH switch wasn't helping. My problem was the Homebrew/node/npm bug found here - https://github.com/npm/npm/issues/3794
If you've already installed node using Homebrew, try ****Note per comments that this might not be safe. It worked for me but could have unintended consequences. It also appears that latest version of Homebrew properly installs npm. So likely I would try brew update
, brew doctor
, brew upgrade node
etc before trying****:
npm update -gf
Or, if you want to install node with Homebrew and have npm work, use:
brew install node --without-npm
curl -L https://npmjs.org/install.sh | sh
you can set the width of right cell to minimum of required width, then apply overflow-hidden+text-overflow to the inside of left cell, but Firefox is buggy here...

For Me Below things Worked -
1.Adding android:clickable="true"
and android:focusableInTouchMode="true"
to the parentLayout
of EditText
i.e android.support.design.widget.TextInputLayout
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusableInTouchMode="true">
<EditText
android:id="@+id/employeeID"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="number"
android:hint="Employee ID"
tools:layout_editor_absoluteX="-62dp"
tools:layout_editor_absoluteY="16dp"
android:layout_marginTop="42dp"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_marginRight="36dp"
android:layout_marginEnd="36dp" />
</android.support.design.widget.TextInputLayout>
2.Overriding dispatchTouchEvent
in Activity class and inserting hideKeyboard()
function
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
if (ev.getAction() == MotionEvent.ACTION_DOWN) {
View view = getCurrentFocus();
if (view != null && view instanceof EditText) {
Rect r = new Rect();
view.getGlobalVisibleRect(r);
int rawX = (int)ev.getRawX();
int rawY = (int)ev.getRawY();
if (!r.contains(rawX, rawY)) {
view.clearFocus();
}
}
}
return super.dispatchTouchEvent(ev);
}
public void hideKeyboard(View view) {
InputMethodManager inputMethodManager =(InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
3.Adding setOnFocusChangeListener
for EditText
EmployeeId.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
hideKeyboard(v);
}
}
});
Do you mean like:
import groovy.json.*
class Me {
String name
}
def o = new Me( name: 'tim' )
println new JsonBuilder( o ).toPrettyString()
select constraint_name,constraint_type
from user_constraints
where table_name = 'YOUR TABLE NAME';
note: table name should be in caps.
In case you don't know the name of the table then,
select constraint_name,constraint_type,table_name
from user_constraints;
Yes, you either need to do this onload
or in a <script>
tag after the closing </body>
tag, when the lc
element is already found in the document's DOM tree.
Please see the GridFS docs for details on storing such binary data.
Support for your specific language should be linked to at the bottom of the screen.
Another option (which is useful e.g. for scientific purposes when you need to work with segmentation masks) is simply apply a threshold:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""Binarize (make it black and white) an image with Python."""
from PIL import Image
from scipy.misc import imsave
import numpy
def binarize_image(img_path, target_path, threshold):
"""Binarize an image."""
image_file = Image.open(img_path)
image = image_file.convert('L') # convert image to monochrome
image = numpy.array(image)
image = binarize_array(image, threshold)
imsave(target_path, image)
def binarize_array(numpy_array, threshold=200):
"""Binarize a numpy array."""
for i in range(len(numpy_array)):
for j in range(len(numpy_array[0])):
if numpy_array[i][j] > threshold:
numpy_array[i][j] = 255
else:
numpy_array[i][j] = 0
return numpy_array
def get_parser():
"""Get parser object for script xy.py."""
from argparse import ArgumentParser, ArgumentDefaultsHelpFormatter
parser = ArgumentParser(description=__doc__,
formatter_class=ArgumentDefaultsHelpFormatter)
parser.add_argument("-i", "--input",
dest="input",
help="read this file",
metavar="FILE",
required=True)
parser.add_argument("-o", "--output",
dest="output",
help="write binarized file hre",
metavar="FILE",
required=True)
parser.add_argument("--threshold",
dest="threshold",
default=200,
type=int,
help="Threshold when to show white")
return parser
if __name__ == "__main__":
args = get_parser().parse_args()
binarize_image(args.input, args.output, args.threshold)
It looks like this for ./binarize.py -i convert_image.png -o result_bin.png --threshold 200

Ive just been searching for a solution and come across Spreadsheetlight
which looks very promising. Its open source and available as a nuget package.
A method to get the greatest power of ten smaller or equal to an integer: (in recursion)
public static int powerOfTen(int n) {
if ( n < 10)
return 1;
else
return 10 * powerOfTen(n/10);
}
The method to reverse the actual integer:(in recursion)
public static int reverseInteger(int i) {
if (i / 10 < 1)
return i ;
else
return i%10*powerOfTen(i) + reverseInteger(i/10);
}
This three lines of code can remove the duplicated element from ArrayList or any collection.
List<Entity> entities = repository.findByUserId(userId);
Set<Entity> s = new LinkedHashSet<Entity>(entities);
entities.clear();
entities.addAll(s);
You can find the setting here in IIS:
It can be found at the server level, web site level, or app level under "ASP".
I think you can set it at the web.config level here. Please confirm this for yourself.

lambda
is an anonymous function, it is equivalent to:
def func(p):
return p.totalScore
Now max
becomes:
max(players, key=func)
But as def
statements are compound statements they can't be used where an expression is required, that's why sometimes lambda
's are used.
Note that lambda
is equivalent to what you'd put in a return statement of a def
. Thus, you can't use statements inside a lambda
, only expressions are allowed.
What does max
do?
max(a, b, c, ...[, key=func]) -> value
With a single iterable argument, return its largest item. With two or more arguments, return the largest argument.
So, it simply returns the object that is the largest.
How does key
work?
By default in Python 2 key
compares items based on a set of rules based on the type of the objects (for example a string is always greater than an integer).
To modify the object before comparison, or to compare based on a particular attribute/index, you've to use the key
argument.
Example 1:
A simple example, suppose you have a list of numbers in string form, but you want to compare those items by their integer value.
>>> lis = ['1', '100', '111', '2']
Here max
compares the items using their original values (strings are compared lexicographically so you'd get '2'
as output) :
>>> max(lis)
'2'
To compare the items by their integer value use key
with a simple lambda
:
>>> max(lis, key=lambda x:int(x)) # compare `int` version of each item
'111'
Example 2: Applying max
to a list of tuples.
>>> lis = [(1,'a'), (3,'c'), (4,'e'), (-1,'z')]
By default max
will compare the items by the first index. If the first index is the same then it'll compare the second index. As in my example, all items have a unique first index, so you'd get this as the answer:
>>> max(lis)
(4, 'e')
But, what if you wanted to compare each item by the value at index 1? Simple: use lambda
:
>>> max(lis, key = lambda x: x[1])
(-1, 'z')
Comparing items in an iterable that contains objects of different type:
List with mixed items:
lis = ['1','100','111','2', 2, 2.57]
In Python 2 it is possible to compare items of two different types:
>>> max(lis) # works in Python 2
'2'
>>> max(lis, key=lambda x: int(x)) # compare integer version of each item
'111'
But in Python 3 you can't do that any more:
>>> lis = ['1', '100', '111', '2', 2, 2.57]
>>> max(lis)
Traceback (most recent call last):
File "<ipython-input-2-0ce0a02693e4>", line 1, in <module>
max(lis)
TypeError: unorderable types: int() > str()
But this works, as we are comparing integer version of each object:
>>> max(lis, key=lambda x: int(x)) # or simply `max(lis, key=int)`
'111'
Note: This solution is old. Please refer to https://facebook.github.io/react-native/docs/images.html#background-image-via-nesting instead
Try this solution. It is officially supported. I have just tested it and works flawlessly.
var styles = StyleSheet.create({
backgroundImage: {
flex: 1,
alignSelf: 'stretch',
width: null,
}
});
And as for using it as Background image, just do the following.
<Image style={styles.backgroundImage}>
<View>
<Text>All your stuff</Text>
</View>
</Image>
In my opinion SET XACT_ABORT ON was made obsolete by the addition of BEGIN TRY/BEGIN CATCH in SQL 2k5. Before exception blocks in Transact-SQL it was really difficult to handle errors and unbalanced procedures were all too common (procedures that had a different @@TRANCOUNT at exit compared to entry).
With the addition of Transact-SQL exception handling is much easier to write correct procedures that are guaranteed to properly balance the transactions. For instance I use this template for exception handling and nested transactions:
create procedure [usp_my_procedure_name]
as
begin
set nocount on;
declare @trancount int;
set @trancount = @@trancount;
begin try
if @trancount = 0
begin transaction
else
save transaction usp_my_procedure_name;
-- Do the actual work here
lbexit:
if @trancount = 0
commit;
end try
begin catch
declare @error int, @message varchar(4000), @xstate int;
select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
if @xstate = -1
rollback;
if @xstate = 1 and @trancount = 0
rollback
if @xstate = 1 and @trancount > 0
rollback transaction usp_my_procedure_name;
raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
end catch
end
go
It allows me to write atomic procedures that rollback only their own work in case of recoverable errors.
One of the main issues Transact-SQL procedures face is data purity: sometimes the parameters received or the data in the tables are just plain wrong, resulting in duplicate key errors, referential constrain errors, check constrain errors and so on and so forth. After all, that's exactly the role of these constrains, if these data purity errors would be impossible and all caught by the business logic, the constrains would be all obsolete (dramatic exaggeration added for effect). If XACT_ABORT is ON then all these errors result in the entire transaction being lost, as opposed to being able to code exception blocks that handle the exception gracefully. A typical example is trying to do an INSERT and reverting to an UPDATE on PK violation.
According to the latest version (1.5.3) there is no fromHTML()
method anymore.
Instead you should utilize jsPDF HTML plugin, see: https://rawgit.com/MrRio/jsPDF/master/docs/module-html.html#~html
You also need to add html2canvas library in order for it to work properly: https://github.com/niklasvh/html2canvas
JS (from API docs):
var doc = new jsPDF();
doc.html(document.body, {
callback: function (doc) {
doc.save();
}
});
You can provide HTML string instead of reference to the DOM element as well.
I had the same issue on my debian server as the disk is full. No temp file could be created as no space left on device. After cleaning some files, it worked out fine.
When you say
(a['x']==1) and (a['y']==10)
You are implicitly asking Python to convert (a['x']==1)
and (a['y']==10)
to boolean values.
NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a boolean value -- in other words, they raise
ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all().
when used as a boolean value. That's because its unclear when it should be True or False. Some users might assume they are True if they have non-zero length, like a Python list. Others might desire for it to be True only if all its elements are True. Others might want it to be True if any of its elements are True.
Because there are so many conflicting expectations, the designers of NumPy and Pandas refuse to guess, and instead raise a ValueError.
Instead, you must be explicit, by calling the empty()
, all()
or any()
method to indicate which behavior you desire.
In this case, however, it looks like you do not want boolean evaluation, you want element-wise logical-and. That is what the &
binary operator performs:
(a['x']==1) & (a['y']==10)
returns a boolean array.
By the way, as alexpmil notes,
the parentheses are mandatory since &
has a higher operator precedence than ==
.
Without the parentheses, a['x']==1 & a['y']==10
would be evaluated as a['x'] == (1 & a['y']) == 10
which would in turn be equivalent to the chained comparison (a['x'] == (1 & a['y'])) and ((1 & a['y']) == 10)
. That is an expression of the form Series and Series
.
The use of and
with two Series would again trigger the same ValueError
as above. That's why the parentheses are mandatory.
I found the error: I have a library that it was built using jdk 1.6. The Spring main controller and components are in this library. And how I use jdk 1.7, It does not find the classes built in 1.6.
The solution was built all using "compiler compliance level: 1.7" and "Generated .class files compatibility: 1.6", "Source compatibility: 1.6".
I setup this option in Eclipse: Preferences\Java\Compiler.
Thanks everybody.
There are probably less than 20 entries in your xml.
change the code to this

The below is the code that i used. It's working perfectly.
var geo = new google.maps.Geocoder;
geo.geocode({'address':address},function(results, status){
if (status == google.maps.GeocoderStatus.OK) {
var myLatLng = results[0].geometry.location;
// Add some code to work with myLatLng
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
Hope this will help.
On the one hand Long is an object, while on the other hand long is a primitive type. In order to compare them you could get the primitive type out of the Long type:
public static void main(String[] args) {
long a = 1111;
Long b = 1113;
if ((b!=null)&&
(a == b.longValue()))
{
System.out.println("Equals");
}
else
{
System.out.println("not equals");
}
}
You need to encode your parameter's values before concatenating them to URL.
Backslash \
is special character which have to be escaped as %5C
Escaping example:
String paramValue = "param\\with\\backslash";
String yourURLStr = "http://host.com?param=" + java.net.URLEncoder.encode(paramValue, "UTF-8");
java.net.URL url = new java.net.URL(yourURLStr);
The result is http://host.com?param=param%5Cwith%5Cbackslash
which is properly formatted url string.
mailx might help as well. From the mailx man page:
-a file
Attach the given file to the message.
Pretty easy, right?
You can run composer show -i
(short for --installed
).
In the latest version just use composer show
.
The -i
options has been deprecated.
You can also use the global
instalation of composer: composer global show
I imported in some files from bridgin header files from cocoapods not in a proper way.
Instead of importing
#import <SomeCocoaPod/SomeCocoaPod.h>
I wrote
#import "SomeCocoaPod.h"
And this was my HUGE mistake
You can use:
cell.getCellTypeEnum()
Further to compare the cell type, you have to use CellType as follows:-
if(cell.getCellTypeEnum() == CellType.STRING){
.
.
.
}
You can Refer to the documentation. Its pretty helpful:-
https://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/Cell.html
string nonNormalized = "\r\n\n\r";
string normalized = nonNormalized.Replace("\r", "\n").Replace("\n", "\r\n");
You need to use parentheses: myList.insert([1, 2, 3])
. When you leave out the parentheses, python thinks you are trying to access myList.insert
at position 1, 2, 3
, because that's what brackets are used for when they are right next to a variable.
For Mac EI caption/Mac Sierra, Chrome extension folders were located at
/Users/$USER/Library/Application\ Support/Google/Chrome/Profile*/Extensions/
It's not entirely clear if you mean you want to find the process who has most pages swapped out or process who caused most pages to be swapped out.
For the first you may run top
and order by swap (press 'Op'), for the latter you can run vmstat
and look for non-zero entries for 'so'.
I had a problem with mime types and where making tests for few file types. It looks like each browser sends it's variation of a mime type for a specific file. I was trying to upload mp3 and zip files with open source php class, that what I have found:
So if you need several file types to upload, you better make some tests so that every browser could upload a file and pass mime type check.
Using LINQ to xml if you are using framework 3.5:
using System.Xml.Linq;
XDocument xmlFile = XDocument.Load("books.xml");
var query = from c in xmlFile.Elements("catalog").Elements("book")
select c;
foreach (XElement book in query)
{
book.Attribute("attr1").Value = "MyNewValue";
}
xmlFile.Save("books.xml");
So the answers above helped, but please allow me to make it clear so other people who aren't very familiar with MS-Windows can work it out in the same way:
This issue happens when Windows 10 installs Anaconda with Python, Ipython, and Jupyter Notebook.
First open the Anaconda Prompt and type the following into the prompt:
jupyter notebook --generate-config
You will get something like this:
You don't have to do anything on the prompt anymore. I didn't snapshot my full address because of privacy, but it shows something like:
C:\Users\name\.jupyter
Find this folder on your C: drive, and in this folder, find the python file jupyter_notebook_config.py
. Drag the file into a Notepad ++ to edit it.
When editing, look around line 214, for the string that looks like:
#c.NotebookApp.notebook_dir = ''
Uncomment it, i.e., delete the "#" in the first column. Now add our target folder address into the ' ' like this:
c.NotebookApp.notebook_dir = 'C:\\Users\\name\\Desktop\\foldername'
Then save the file. Then open anaconda prompt again, type jupyter notebook
. This should launch Jupyter Notebook in the browser in the folder with the above address. Here, the key point is to UNCOMMENT (which means to delete) the # at front of the line, and then, USE \\ double slashes (for the path separator) between folders. If you use only single slashes \, it won't work.
That's all.
I tried the following and it works for me better
Code:
.unstyled-link{
color: inherit;
text-decoration: inherit;
&:link,
&:hover {
color: inherit;
text-decoration: inherit;
}
}
If you want to use socket.io together with php this may be your answer!
project website:
they are also on github:
https://github.com/wisembly/elephant.io
Elephant.io provides a socket.io client fully written in PHP that should be usable everywhere in your project.
It is a light and easy to use library that aims to bring some real-time functionality to a PHP application through socket.io and websockets for actions that could not be done in full javascript.
example from the project website (communicate with websocket server through php)
php server
use ElephantIO\Client as Elephant;
$elephant = new Elephant('http://localhost:8000', 'socket.io', 1, false, true, true);
$elephant->init();
$elephant->send(
ElephantIOClient::TYPE_EVENT,
null,
null,
json_encode(array('name' => 'foo', 'args' => 'bar'))
);
$elephant->close();
echo 'tryin to send `bar` to the event `foo`';
socket io server
var io = require('socket.io').listen(8000);
io.sockets.on('connection', function (socket) {
console.log('user connected!');
socket.on('foo', function (data) {
console.log('here we are in action event and data is: ' + data);
});
});
Here is the code that works for me. The key is that you need a wrapper class.
public class Person {
private String name;
private Integer age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public String toString() {
return "Person [name=" + name + ", age=" + age + "]";
}
A PersonWrapper class
public class PersonWrapper {
private List<Person> persons;
/**
* @return the persons
*/
public List<Person> getPersons() {
return persons;
}
/**
* @param persons the persons to set
*/
public void setPersons(List<Person> persons) {
this.persons = persons;
}
}
My Controller methods
@RequestMapping(value="person", method=RequestMethod.POST,consumes="application/json",produces="application/json")
@ResponseBody
public List<String> savePerson(@RequestBody PersonWrapper wrapper) {
List<String> response = new ArrayList<String>();
for (Person person: wrapper.getPersons()){
personService.save(person);
response.add("Saved person: " + person.toString());
}
return response;
}
The request sent is json in POST
{"persons":[{"name":"shail1","age":"2"},{"name":"shail2","age":"3"}]}
And the response is
["Saved person: Person [name=shail1, age=2]","Saved person: Person [name=shail2, age=3]"]
EDIT: This is no longer the right way to use refs with Typescript. Look at Jeff Bowen's answer and upvote it to increase its visibility.
Found the answer to the problem. Use refs as below inside the class.
refs: {
[key: string]: (Element);
stepInput: (HTMLInputElement);
}
Thanks @basarat for pointing in the right direction.
Likely you have bad data that cannot convert. Dates should never be stored in varchar becasue it will allow dates such as ASAP or 02/30/2009. Use the isdate() function on your data to find the records which can't convert.
OK I tested with known good data and still got the message. You need to convert to a different format becasue it does not know if 12302009 is mmddyyyy or ddmmyyyy. The format of yyyymmdd is not ambiguous and SQL Server will convert it correctly
I got this to work:
cast( right(@date,4) + left(@date,4) as datetime)
You will still get an error message though if you have any that are in a non-standard format like '112009' or some text value or a true out of range date.
Yep, just add parenthesis (calling the function). Make sure the function is in scope and actually returns something.

It is 253 == 9 007 199 254 740 992. This is because Number
s are stored as floating-point in a 52-bit mantissa.
The min value is -253.
This makes some fun things happening
Math.pow(2, 53) == Math.pow(2, 53) + 1
>> true
And can also be dangerous :)
var MAX_INT = Math.pow(2, 53); // 9 007 199 254 740 992
for (var i = MAX_INT; i < MAX_INT + 2; ++i) {
// infinite loop
}

Following Stuart's idea, this could be done with a Spliterator
like this:
static <T> Stream<T> defaultIfEmpty(Stream<T> stream, Stream<T> defaultStream) {
final Spliterator<T> spliterator = stream.spliterator();
final AtomicReference<T> reference = new AtomicReference<>();
if (spliterator.tryAdvance(reference::set)) {
return Stream.concat(Stream.of(reference.get()), StreamSupport.stream(spliterator, stream.isParallel()));
} else {
return defaultStream;
}
}
I think this works with parallel Streams as the stream.spliterator()
operation will terminate the stream, and then rebuild it as required
In my use-case I needed a default Stream
rather than a default value. that's quite easy to change if this is not what you need
The creator of the file (doesn't have to put any code in) has to put their name in the file. So if you create stubs or placeholders, you "own" them forever.
The guy who actually writes the code doesn't add his name; we had source control so that we'd know, always who to blame.
PHP parser errors take some getting used to; if it complains about an unexpected 'something' at line X, look at line X-1 first. In this case it will not tell you that you forgot a semi-colon at the end of the previous line , instead it will complain about the if
that comes next.
You'll get used to it :)
I was facing the same problem. I have deleted the target folder and run maven install, it worked.
It's very simple to control custom messages with the help of HTML5
event oninvalid
Here is code:
<input id="UserID" type="text" required="required"
oninvalid="this.setCustomValidity('Witinnovation')"
onvalid="this.setCustomValidity('')">
This is most important:
onvalid="this.setCustomValidity('')"
just use this:
<script>
var ctx = document.getElementById("myChart").getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["1","2","3","4","5","6","7","8","9","10","11",],
datasets: [{

To make the images flexible, simply add
max-width:100%
andheight:auto
. Imagemax-width:100%
andheight:auto
works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to addwidth:auto\9
for IE8.source: http://webdesignerwall.com/tutorials/responsive-design-with-css3-media-queries
for example :
img {
max-width: 100%;
height: auto;
width: auto\9; /* ie8 */
}
and then any images you add simply using the img tag will be flexible
JSFiddle example here. No JavaScript required. Works in latest versions of Chrome, Firefox and IE (which is all I've tested).
The the easyest way = Environment.ProcessorCount
Exemple from Environment.ProcessorCount Property
using System;
class Sample

public static void Main()
{
Console.WriteLine("The number of processors " +
"on this computer is {0}.",
Environment.ProcessorCount);
}
}
You can create GitHub repositories via the command line using their Repositories API (http://develop.github.com/p/repo.html)
Check Creating github repositories with command line | Do it yourself Android for example usage.
this is may be due to the thing that you have created your .jsp or the .html file in the WEB-INF instead of the WebContent folder.
Solution: Just replace the files that are there in the WEB-INF folder to the Webcontent folder and try executing the same - You will get the appropriate output
Function makeRed
and makeBlack
use queue
and dequeue
to execute each other. The effect is that, the '#wow' element blinks continuously.
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#wow').click(function(){
$(this).delay(200).queue(makeRed);
});
});
function makeRed(){
$('#wow').css('color', 'red');
$('#wow').delay(200).queue(makeBlack);
$('#wow').dequeue();
}
function makeBlack(){
$('#wow').css('color', 'black');
$('#wow').delay(200).queue(makeRed);
$('#wow').dequeue();
}
</script>
</head>
<body>
<div id="wow"><p>wow</p></div>
</body>
</html>
The simplest way to do this without needing to create anything extra would be to just modify the simple list TextView
:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, strings) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView textView = (TextView) super.getView(position, convertView, parent);
textView.setTextColor({YourColorHere});
return textView;
}
};

You can use Google PDF Viewer to read your pdf online:
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
String pdf = "http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters.pdf";
webview.loadUrl("https://drive.google.com/viewerng/viewer?embedded=true&url=" + pdf);
If you are using moment.js in your application.
var x= moment(new Date()).format('DD/MM/YYYY hh:mm:ss')
Pass x
to codebehind function and accept it as a string parameter. Use the DateTime.ParseExact()
in c# to convert this string to DateTime as follows,
DateTime.ParseExact(YourString, "dd/MM/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
Select 'YOU WILL SEE ME' as ANSWER from dual
where exists (select 1 from dual where 1 = 1);
Select 'YOU CAN NOT SEE ME' as ANSWER from dual
where exists (select 1 from dual where 1 = 0);
Select 'YOU WILL SEE ME, TOO' as ANSWER from dual
where not exists (select 1 from dual where 1 = 0);
Rails-specific
In case someone only needs to call to_s
method to each of the values and is not using Rails 4.2 ( which includes transform_values
method link), you can do the following:
original_hash = { :a => 'a', :b => BigDecimal('23.4') }
#=> {:a=>"a", :b=>#<BigDecimal:5c03a00,'0.234E2',18(18)>}
JSON(original_hash.to_json)
#=> {"a"=>"a", "b"=>"23.4"}
Note: The use of 'json' library is required.
Note 2: This will turn keys into strings as well

I've found a temporary solution that will at least let me process this job. I wrote a short AutoIt script that waits for the "Update Links" window to appear, then clicks the "Don't Update" button. Code is as follows:
while 1
if winexists("Microsoft Excel","This workbook contains links to other data sources.") Then
controlclick("Microsoft Excel","This workbook contains links to other data sources.",2)
EndIf
WEnd
So far this seems to be working. I'd really like to find a solution that's entirely VBA, however, so that I can make this a standalone application.
The PHP way of doing this is simple:
$out = strlen($in) > 50 ? substr($in,0,50)."..." : $in;
But you can achieve a much nicer effect with this CSS:
.ellipsis {
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
}
Now, assuming the element has a fixed width, the browser will automatically break off and add the ...
for you.
For Ubuntu/Linux users: -
the command is either pkill
or killall
. pkill
is generally recommended, since on some systems, killall
will actually kill all processes.
We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext
.
In a standalone application, you can specify that as below
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");
Context ctx = new InitialContext(env);
But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext
as below
System.getProperty(Context.PROVIDER_URL);
and
these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work
InitialContext ctx = new InitialContext();
It also seems to occur frequently when you connect to the device using the Wi-Fi mode (in Android Studio or in the console by running adb tcpip 5555
for example).
To fix:
adb kill-server
to ensure adb is not running.adb devices
. This should start the ADB daemon. Your device should now be online again.Pair would be a good stuff, to be a basic construction unit for a complex generics, for instance, this is from my code:
WeakHashMap<Pair<String, String>, String> map = ...
It is just the same as Haskell's Tuple
Google Drive folders can be embedded and displayed in list
and grid
views:
<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>
<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>
Q: What is a folder ID (FOLDER-ID) and how can I get it?
A: Go to Google Drive >> open the folder >> look at its URL in the address bar of your browser. For example:
Folder URL: https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2
Folder ID:
0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2
This technique works best for folders with public access. Folders that are shared only with certain Google accounts will cause trouble when you embed them this way. At the time of this edit, a message "You need permission" appears, with some buttons to help you "Request access" or "Switch accounts" (or possibly sign-in to a Google account). The Javascript in these buttons doesn't work properly inside an IFRAME
in Chrome.

Same problem here, i tried some solutions and the best for me is following:
In initialize-method of controller, create an empty observableList and set it to the table:
obsBericht = FXCollections.observableList(new ArrayList<Bericht>(0));
tblBericht.setItems(obsBericht);
In your update-method, just use the observableList, clear it and add the refreshed data:
obsBericht.clear();
obsBericht.addAll(FXCollections.observableList(DatabaseHelper.getBerichte()));
// tblBericht.setItems(obsBericht);
It's not necessary to set the items of the table again
$anchorScroll
works for this, but there's a much better way to use it in more recent versions of Angular.
Now, $anchorScroll
accepts the hash as an optional argument, so you don't have to change $location.hash
at all. (documentation)
This is the best solution because it doesn't affect the route at all. I couldn't get any of the other solutions to work because I'm using ngRoute and the route would reload as soon as I set $location.hash(id)
, before $anchorScroll
could do its magic.
Here is how to use it... first, in the directive or controller:
$scope.scrollTo = function (id) {
$anchorScroll(id);
}
and then in the view:
<a href="" ng-click="scrollTo(id)">Text</a>
Also, if you need to account for a fixed navbar (or other UI), you can set the offset for $anchorScroll like this (in the main module's run function):
.run(function ($anchorScroll) {
//this will make anchorScroll scroll to the div minus 50px
$anchorScroll.yOffset = 50;
});
In the absence of jQuery, I would use something like this:
<script>
var divsToHide = document.getElementsByClassName("classname"); //divsToHide is an array
for(var i = 0; i < divsToHide.length; i++){
divsToHide[i].style.visibility = "hidden"; // or
divsToHide[i].style.display = "none"; // depending on what you're doing
}
<script>
This is taken from this SO question: Hide div by class id, however seeing that you're asking for "old-school" JS solution, I believe that getElementsByClassName is only supported by modern browsers
If anyone's still stuck on this, the easiest solution I found was to "Retarget Solution". In my case, the project was built of SDK 8.1, upgrading to VS2017 brought with it SDK 10.0.xxx.
To retarget solution: Project->Retarget Solution->"Select whichever SDK you have installed"->OK
From there on you can simply build/debug your solution. Hope it helps
In my case I had all of the proper references in my project. I found that by building the solution the nuget packages were automatically restored.
I think things (location) have changed little bit. For: Android Studio 1.2.1.1 Build @AI-141.1903250 - built on May 5, 2015
Franco Rondinis answer should be
To track memory allocation of objects:
Try redirecting the output to Out-Null. Like so,
$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null
The three operators have related but different meanings, despite the misleading note from the IDE.
The ::
operator is known as the scope resolution operator, and it is used to get from a namespace or class to one of its members.
The .
and ->
operators are for accessing an object instance's members, and only comes into play after creating an object instance. You use .
if you have an actual object (or a reference to the object, declared with &
in the declared type), and you use ->
if you have a pointer to an object (declared with *
in the declared type).
The this
object is always a pointer to the current instance, hence why the ->
operator is the only one that works.
Examples:
// In a header file
namespace Namespace {
class Class {
private:
int x;
public:
Class() : x(4) {}
void incrementX();
};
}
// In an implementation file
namespace Namespace {
void Class::incrementX() { // Using scope resolution to get to the class member when we aren't using an instance
++(this->x); // this is a pointer, so using ->. Equivalent to ++((*this).x)
}
}
// In a separate file lies your main method
int main() {
Namespace::Class myInstance; // instantiates an instance. Note the scope resolution
Namespace::Class *myPointer = new Namespace::Class;
myInstance.incrementX(); // Calling a function on an object instance.
myPointer->incrementX(); // Calling a function on an object pointer.
(*myPointer).incrementX(); // Calling a function on an object pointer by dereferencing first
return 0;
}
There are multiple ways like -
<select ng-init="feed.config = options[0]" ng-model="feed.config"
ng-options="template.value as template.name for template in feed.configs">
</select>
Or
$scope.feed.config = $scope.configs[0].name;
New, resurrected project site (Win7 compability and more!): http://sshwindows.sourceforge.net
1st January 2012
- OpenSSH for Windows 5.6p1-2 based release created!!
- Happy New Year all! Since COpSSH has started charging I've resurrected this project
- Updated all binaries to current releases
- Added several new supporting DLLs as required by all executables in package
- Renamed switch.exe to bash.exe to remove the need to modify and compile mkpasswd.exe each build
- Please note there is a very minor bug in this release, detailed in the docs. I'm working on fixing this, anyone who can code in C and can offer a bit of help it would be much appreciated
Have you tried using lazy evaluation of expressions like disabled || someAction()
?
Lets assume I defined something like so in my controller:
$scope.disabled = true;
Then I can disabling a link and apply inline styles like so:
<a data-ng-click="disabled || (GoTo('#/employer/'))" data-ng-style="disabled && { 'background-color': 'rgba(99, 99, 99, 0.5)', }">Higher Level</a>
Or better still disable a link and apply a class like so:
<a data-ng-click="disabled || (GoTo('#/employer/'))" data-ng-class="{ disabled: disabled }">Higher Level</a>
Note: that you will have a class="disabled"
applied to DOM element by that statement.
At this stage you just need to handle what you action GoTo()
will do. In my case its as simple as redirect to associated state:
$scope.GoTo = function (state) {
if (state != undefined && state.length > 0) {
$window.location.hash = state;
}
};
Rather than being limited by ngDisabled
you are limited by what you decide to do.
With this technique I successfully applied permission level checking to enable or disable user access to certain part of my module.
many times i have noticed that site wit shared hosting do not allow to change settings in php.ini files. one also can not even crate .htaaccess file at all. in such situation one can try following things

ini_set('post_max_size', '10M');
ini_set('max_input_time', 300);
ini_set('max_execution_time', 300);

two ways:
x = [0] * 10
x = [0 for i in xrange(10)]
Edit: replaced range
by xrange
to avoid creating another list.
Also: as many others have noted including Pi and Ben James, this creates a list
, not a Python array. While a list is in many cases sufficient and easy enough, for performance critical uses (e.g. when duplicated in thousands of objects) you could look into python arrays. Look up the array
module, as explained in the other answers in this thread.
This error caused because of output buffering modules extension(ob_gzhandler) added. While output buffering use at starting ob_start() and ending ob_flush()
<?php
ob_start( 'ob_gzhandler' );
echo json_encode($array);
ob_end_flush();
?>
Use this:
<?php
ob_start();
echo json_encode($array);
ob_flush();

@Fox: great answer! Here's a bit of an extension with some more options. It's what I've been using lately as a go-to solution:
var fs = require('fs');
fs.lstat( targetPath, function (err, inodeStatus) {
if (err) {
// file does not exist-
if (err.code === 'ENOENT' ) {
console.log('No file or directory at',targetPath);
return;
}
// miscellaneous error (e.g. permissions)
console.error(err);
return;
}
// Check if this is a file or directory
var isDirectory = inodeStatus.isDirectory();
// Get file size
//
// NOTE: this won't work recursively for directories-- see:
// http://stackoverflow.com/a/7550430/486547
//
var sizeInBytes = inodeStatus.size;
console.log(
(isDirectory ? 'Folder' : 'File'),
'at',targetPath,
'is',sizeInBytes,'bytes.'
);
}
P.S. check out fs-extra if you aren't already using it-- it's pretty sweet. https://github.com/jprichardson/node-fs-extra)

You can use the substring method:
String aString = "This.is.a.great.place.too.work.";
String aSubstring = "work";
String endString = aString.substring(aString.length() -
(aSubstring.length() + 1),aString.length() - 1);
if ( endString.equals(aSubstring) )
System.out.println("Equal " + aString + " " + aSubstring);
else
System.out.println("NOT equal " + aString + " " + aSubstring);
HTML does not support a dropdown list with checkboxes. You can have a dropdown list, or a checkbox list. You could possibly fake a dropdowncheckbox list using javascript and hiding divs, but that would be less reliable than just a standard checkbox list.
There are of course 3rd party controls that look like a dropdown checkboxlist, but they are using the div tricks.
you could also use a double listbox, which handles multi select by moving items back and forth between two lists. This has the added benefit of being easily to see all the selected items at once, even though the list of total items is long
(Imagine a list of every city in the world, with only the first and last selected)
If your testing requires pulling quasi-real credit reports from the bureaus, the inactive SSNs of other answers won't work and you'll need designated test numbers.
I found this site Which appears to contain test social security numbers with associated test names and credit card numbers.
Transunion has a test environment you can link and send data to, including associated dummy credit reports. Sending a SSN to them with certain numbers in certain positions will automatically route the inquiry to their test environment Other credit bureaus will have similar systems in place.

If a value in YAML begins with a curly brace ({
), the YAML parser assumes that it is a dictionary. So, for cases like this where there is a (Jinja2) variable in the value, one of the following two strategies needs to be adopted to avoiding confusing the YAML parser:
Quote the whole command:
- command: "{{ item }} chdir=/src/package/"
with_items:
- ./configure
- /usr/bin/make
- /usr/bin/make install
or change the order of the arguments:
- command: chdir=/src/package/ {{ item }}
with_items:
- ./configure
- /usr/bin/make
- /usr/bin/make install
Thanks for @RamondelaFuente alternative suggestion.
Amiram's answer is correct, but Distinct() as implemented is an N2 operation; for each item in the list, the algorithm compares it to all the already processed elements, and returns it if it's unique or ignores it if not. We can do better.
A sorted list can be deduped in linear time; if the current element equals the previous element, ignore it, otherwise return it. Sorting is NlogN, so even having to sort the collection, we get some benefit:
public static IEnumerable<T> SortAndDedupe<T>(this IEnumerable<T> input)
{
var toDedupe = input.OrderBy(x=>x);
T prev;
foreach(var element in toDedupe)
{
if(element == prev) continue;
yield return element;
prev = element;
}
}
//Usage
dtList = dtList.Where(s => !string.IsNullOrWhitespace(s)).SortAndDedupe().ToList();
This returns the same elements; they're just sorted.

Why do you want to use multiple [ng-app] ? Since Angular is resumed by using modules, you can use an app that use multiple dependencies.
Javascript:
// setter syntax -> initializing other module for demonstration
angular.module('otherModule', []);
angular.module('app', ['otherModule'])
.controller('AppController', function () {
// ...do something
});
// getter syntax
angular.module('otherModule')
.controller('OtherController', function () {
// ...do something
});
HTML:
<div ng-app="app">
<div ng-controller="AppController">...</div>
<div ng-controller="OtherController">...</div>
</div>
EDIT
Keep in mind that if you want to use controller inside controller you have to use the controllerAs syntax, like so:
<div ng-app="app">
<div ng-controller="AppController as app">
<div ng-controller="OtherController as other">...</div>
</div>
</div>

One of my friends is writing a graphics app using NVIDIA CUDA. Application fits in very nicely with OOP paradigm and the problem can be decomposed into modules neatly. However, to use CUDA you need to use C, which doesn't support inheritance. Therefore, you need to be clever.
a) You devise a clever system which will emulate inheritance to a certain extent. It can be done!
i) You can use a hook system, which expects every child C of parent P to have a certain override for function F. You can make children register their overrides, which will be stored and called when required.
ii) You can use struct memory alignment feature to cast children into parents.
This can be neat but it's not easy to come up with future-proof, reliable solution. You will spend lots of time designing the system and there is no guarantee that you won't run into problems half-way through the project. Implementing multiple inheritance is even harder, if not almost impossible.
b) You can use consistent naming policy and use divide and conquer approach to create a program. It won't have any inheritance but because your functions are small, easy-to-understand and consistently formatted you don't need it. The amount of code you need to write goes up, it's very hard to stay focused and not succumb to easy solutions (hacks). However, this ninja way of coding is the C way of coding. Staying in balance between low-level freedom and writing good code. Good way to achieve this is to write prototypes using a functional language. For example, Haskell is extremely good for prototyping algorithms.
I tend towards approach b. I wrote a possible solution using approach a, and I will be honest, it felt very unnatural using that code.
You may use the ==
operator to compare unicode objects for equality.
>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>>
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>>
But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode
object to a str
object, like so:
>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False
See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.
Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.
I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."
You can initialize the array by specifying the dimensions. For example
Dim myArray(10) As Integer
Dim myArray(1 to 10) As Integer
If you are working with arrays and if this is your first time then I would recommend visiting Chip Pearson's WEBSITE.
What does this initialize to? For example, what if I want to initialize the entire array to 13?
When you want to initailize the array of 13 elements then you can do it in two ways
Dim myArray(12) As Integer
Dim myArray(1 to 13) As Integer
In the first the lower bound of the array would start with 0
so you can store 13 elements in array. For example
myArray(0) = 1
myArray(1) = 2
'
'
'
myArray(12) = 13
In the second example you have specified the lower bounds as 1
so your array starts with 1
and can again store 13 values
myArray(1) = 1
myArray(2) = 2
'
'
'
myArray(13) = 13
Wnen you initialize an array using any of the above methods, the value of each element in the array is equal to 0
. To check that try this code.
Sub Sample()
Dim myArray(12) As Integer
Dim i As Integer
For i = LBound(myArray) To UBound(myArray)
Debug.Print myArray(i)
Next i
End Sub
or
Sub Sample()
Dim myArray(1 to 13) As Integer
Dim i As Integer
For i = LBound(myArray) To UBound(myArray)
Debug.Print myArray(i)
Next i
End Sub
FOLLOWUP FROM COMMENTS
So, in this example every value would be 13. So if I had an array Dim myArray(300) As Integer, all 300 elements would hold the value 13
Like I mentioned, AFAIK, there is no direct way of achieving what you want. Having said that here is one way which uses worksheet function Rept
to create a repetitive string of 13's. Once we have that string, we can use SPLIT
using ","
as a delimiter. But note this creates a variant array but can be used in calculations.
Note also, that in the following examples myArray
will actually hold 301 values of which the last one is empty - you would have to account for that by additionally initializing this value or removing the last "," from sNum
before the Split
operation.
Sub Sample()
Dim sNum As String
Dim i As Integer
Dim myArray
'~~> Create a string with 13 three hundred times separated by comma
'~~> 13,13,13,13...13,13 (300 times)
sNum = WorksheetFunction.Rept("13,", 300)
sNum = Left(sNum, Len(sNum) - 1)
myArray = Split(sNum, ",")
For i = LBound(myArray) To UBound(myArray)
Debug.Print myArray(i)
Next i
End Sub
Using the variant array in calculations
Sub Sample()
Dim sNum As String
Dim i As Integer
Dim myArray
'~~> Create a string with 13 three hundred times separated by comma
sNum = WorksheetFunction.Rept("13,", 300)
sNum = Left(sNum, Len(sNum) - 1)
myArray = Split(sNum, ",")
For i = LBound(myArray) To UBound(myArray)
Debug.Print Val(myArray(i)) + Val(myArray(i))
Next i
End Sub
Turns out it needs to be specified via escaped unicode. This question is related and contains the answer.
The solution:
h2:after {
content: "\00a0";
}
merged = map(names(first), ~c(first[[.x]], second[[.x]])
merged = set_names(merged, names(first))
Using purrr. Also solves the problem of your lists not being in order.
In MongoDB To insert Json array data from file(from particular location from a system / pc) using mongo shell command. While executing below command, command should be in single line.
var file = cat('I:/data/db/card_type_authorization.json'); var o = JSON.parse(file); db.CARD_TYPE_AUTHORIZATION.insert(o);
JSON File: card_type_authorization.json
[{
"code": "visa",
"position": 1,
"description": "Visa",
"isVertualCard": false,
"comments": ""
},{
"code": "mastercard",
"position": 2,
"description": "Mastercard",
"isVertualCard": false,
"comments": ""
}]
My favourite way to do this is fairly simple:
if (false !== ($data = file_get_contents("http://www.google.com"))) {
$error = error_get_last();
echo "HTTP request failed. Error was: " . $error['message'];
} else {
echo "Everything went better than expected";
}
I found this after experimenting with the try/catch
from @enobrev above, but this allows for less lengthy (and IMO, more readable) code. We simply use error_get_last
to get the text of the last error, and file_get_contents
returns false on failure, so a simple "if" can catch that.
I found netlimiter4 to be the best solution for throttling data to emulators. It provides for granular control through a decent gui and gives you graphical feedback on the data throughput to each process. Currently in a free beta. screenshot

There are apps available on the play store to throttle to actual devices but they require root(I cant provide any advice as to how well they work, if at at all - YMMV.)

Python 2.7 and 3.2 added the collections.Counter
class, which is a dictionary subclass that maps elements to the number of occurrences of the element. This can be used as a multiset. You can do something like this:
from collections import Counter
a = Counter([0, 1, 2, 1, 0])
b = Counter([0, 1, 1])
c = a - b # ignores items in b missing in a
print(list(c.elements())) # -> [0, 2]
As well, if you want to check that every element in b
is in a
:
# a[key] returns 0 if key not in a, instead of raising an exception
assert all(a[key] >= b[key] for key in b)
But since you are stuck with 2.5, you could try importing it and define your own version if that fails. That way you will be sure to get the latest version if it is available, and fall back to a working version if not. You will also benefit from speed improvements if if gets converted to a C implementation in the future.
try:
from collections import Counter
except ImportError:
class Counter(dict):
...

I use this function (SQL Server 2005 and above).
create function [dbo].[Split]
(
@string nvarchar(4000),
@delimiter nvarchar(10)
)
returns @table table
(
[Value] nvarchar(4000)
)
begin
declare @nextString nvarchar(4000)
declare @pos int, @nextPos int
set @nextString = ''
set @string = @string + @delimiter
set @pos = charindex(@delimiter, @string)
set @nextPos = 1
while (@pos <> 0)
begin
set @nextString = substring(@string, 1, @pos - 1)
insert into @table
(
[Value]
)
values
(
@nextString
)
set @string = substring(@string, @pos + len(@delimiter), len(@string))
set @nextPos = @pos
set @pos = charindex(@delimiter, @string)
end
return
end
The objects in the list must have toString
implemented for them to print something meaningful to screen.
Here's a quick test to see the differences:
public class Test {
public class T1 {
public Integer x;
}
public class T2 {
public Integer x;
@Override
public String toString() {
return x.toString();
}
}
public void run() {
T1 t1 = new T1();
t1.x = 5;
System.out.println(t1);
T2 t2 = new T2();
t2.x = 5;
System.out.println(t2);
}
public static void main(String[] args) {
new Test().run();
}
}
And when this executes, the results printed to screen are:
t1 = Test$T1@19821f
t2 = 5
Since T1 does not override the toString method, its instance t1 prints out as something that isn't very useful. On the other hand, T2 overrides toString, so we control what it prints when it is used in I/O, and we see something a little better on screen.

Well, the only way I can think of doing everything you want is pretty ugly. First perform an AJAX call to retrieve the Javascript file contents. When this completes you can check the status code to decide if this was successful or not. Then take the responseText from the xhr object and wrap it in a try/catch, dynamically create a script tag, and for IE you can set the text property of the script tag to the JS text, in all other browsers you should be able to append a text node with the contents to script tag. If there's any code that expects a script tag to actually contain the src location of the file, this won't work, but it should be fine for most situations.

The question is little unclear because the title of the question is asking about string and set conversion but then the question at the end asks how do I serialize ? !
let me refresh the concept of Serialization is the process of encoding an object, including the objects it refers to, as a stream of byte data.
If interested to serialize you can use:
json.dumps -> serialize
json.loads -> deserialize
If your question is more about how to convert set to string and string to set then use below code (it's tested in Python 3)
String to Set
set('abca')
Set to String
''.join(some_var_set)
example:
def test():
some_var_set=set('abca')
print("here is the set:",some_var_set,type(some_var_set))
some_var_string=''.join(some_var_set)
print("here is the string:",some_var_string,type(some_var_string))
test()
//get main activity
final Activity main_activity=getActivity();
//list view click listener
final ListView listView = (ListView) inflatedView.findViewById(R.id.listView_id);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String stringText;
//in normal case
stringText= ((TextView)view).getText().toString();
//in case if listview has separate item layout
TextView textview=(TextView)view.findViewById(R.id.textview_id_of_listview_Item);
stringText=textview.getText().toString();
//show selected
Toast.makeText(main_activity, stringText, Toast.LENGTH_LONG).show();
}
});

I have tried everything above, but none could solve my problem. I fixed it by updating the old version of youtube-dl to download playlist. To update it
sudo youtube-dl -U

If you only have a single newline in the input, just doing
std::cin.ignore();
will work fine. It reads and discards the next character from the input.
But if you have anything else still in the input, besides the newline (for example, you read one word but the user entered two words), then you have to do
std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
See e.g. this reference of the ignore
function.
To be even more safe, do the second alternative above in a loop until gcount
returns zero.
There is a patch for Eclipse:
https://bugs.eclipse.org/bugs/attachment.cgi?id=262418&action=edit
Download this patch and put it to the plugins directory of your Eclipse installation. It will replace the default "org.eclipse.jst.server.tomcat.core_1.1.800.v201602282129.jar".
NOTE
After you add this patch you must choose "Apache Tomcat v9.0" when adding a server runtime environment in the Eclipse (Preferences > Server > Runtime Environments).
I.e. this patch allows you to select either Tomcat version 9.x or Tomcat version 8.5.x when adding Apache Tomcat v.9.0 runtime environment.

Private constructor means a user cannot directly instantiate a class. Instead, you can create objects using something like the Named Constructor Idiom, where you have static
class functions that can create and return instances of a class.
The Named Constructor Idiom is for more intuitive usage of a class. The example provided at the C++ FAQ is for a class that can be used to represent multiple coordinate systems.
This is pulled directly from the link. It is a class representing points in different coordinate systems, but it can used to represent both Rectangular and Polar coordinate points, so to make it more intuitive for the user, different functions are used to represent what coordinate system the returned Point
represents.
#include <cmath> // To get std::sin() and std::cos()
class Point {
public:
static Point rectangular(float x, float y); // Rectangular coord's
static Point polar(float radius, float angle); // Polar coordinates
// These static methods are the so-called "named constructors"
...
private:
Point(float x, float y); // Rectangular coordinates
float x_, y_;
};
inline Point::Point(float x, float y)
: x_(x), y_(y) { }
inline Point Point::rectangular(float x, float y)
{ return Point(x, y); }
inline Point Point::polar(float radius, float angle)
{ return Point(radius*std::cos(angle), radius*std::sin(angle)); }
There have been a lot of other responses that also fit the spirit of why private constructors are ever used in C++ (Singleton pattern among them).
Another thing you can do with it is to prevent inheritance of your class, since derived classes won't be able to access your class' constructor. Of course, in this situation, you still need a function that creates instances of the class.

MSDN seems to indicate that the Cxxx casts for specific types can improve performance in VB .NET because they are converted to inline code. For some reason, it also suggests DirectCast as opposed to CType in certain cases (the documentations states it's when there's an inheritance relationship; I believe this means the sanity of the cast is checked at compile time and optimizations can be applied whereas CType always uses the VB runtime.)
When I'm writing VB .NET code, what I use depends on what I'm doing. If it's prototype code I'm going to throw away, I use whatever I happen to type. If it's code I'm serious about, I try to use a Cxxx cast. If one doesn't exist, I use DirectCast if I have a reasonable belief that there's an inheritance relationship. If it's a situation where I have no idea if the cast should succeed (user input -> integers, for example), then I use TryCast so as to do something more friendly than toss an exception at the user.
One thing I can't shake is I tend to use ToString instead of CStr but supposedly Cstr is faster.
Sql Server does not (on my knowledge) have in-build Split function. Split function in general on all platforms would have comma-separated string value to be split into individual strings. In sql server, the main objective or necessary of the Split function is to convert a comma-separated string value (‘abc,cde,fgh’) into a temp table with each string as rows.
The below Split function is Table-valued function which would help us splitting comma-separated (or any other delimiter value) string to individual string.
CREATE FUNCTION dbo.Split(@String varchar(8000), @Delimiter char(1))
returns @temptable TABLE (items varchar(8000))
as
begin
declare @idx int
declare @slice varchar(8000)
select @idx = 1
if len(@String)<1 or @String is null return
while @idx!= 0
begin
set @idx = charindex(@Delimiter,@String)
if @idx!=0
set @slice = left(@String,@idx - 1)
else
set @slice = @String
if(len(@slice)>0)
insert into @temptable(Items) values(@slice)
set @String = right(@String,len(@String) - @idx)
if len(@String) = 0 break
end
return
end
select top 10 * from dbo.split('Chennai,Bangalore,Mumbai',',')

Open angular.json file and find budgets
keyword.
It should look like:
"budgets": [
{
"type": "initial",
"maximumWarning": "2mb",
"maximumError": "5mb"
}
]
As you’ve probably guessed you can increase the maximumWarning
value to prevent this warning, i.e.:
"budgets": [
{
"type": "initial",
"maximumWarning": "4mb", <===
"maximumError": "5mb"
}
]
A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.
In our case budget is the limit for bundle sizes.

I made it a bit different (with tess-two). Maybe it will be useful for somebody.
So you need to initialize first the API.
TessBaseAPI baseApi = new TessBaseAPI();
baseApi.init(datapath, language, ocrEngineMode);
Then set the following variables
baseApi.setPageSegMode(TessBaseAPI.PageSegMode.PSM_SINGLE_LINE);
baseApi.setVariable(TessBaseAPI.VAR_CHAR_BLACKLIST, "!?@#$%&*()<>_-+=/:;'\"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz");
baseApi.setVariable(TessBaseAPI.VAR_CHAR_WHITELIST, ".,0123456789");
baseApi.setVariable("classify_bln_numeric_mode", "1");
In this way the engine will check only the numbers.

Just go to the official Node.js site (nodejs.org), download and execute the installer program.
It will take care of everything and with a few clicks of 'Next' you'll get the latest Node.js version running on your machine. Since 2020 it's the recommended way to update NodeJS. It's the easiest and least frustrating solution.
Pro tips
NodeJS installation includes NPM (Node package manager).
To check your NPM version use npm version
or node --version
.
If you prefer CLI, to update NPM use npm install -g npm
and then npm install -g node
.
For more details, see the docs for install
command.
Keep an eye on NodeJS blog - Vulnerabilities so you don't miss important security releases. Keep your NodeJS up-to-date.
Operating systems supported by Node.js: Windows, Linux, MacOS, SunOS, IBM AIX.
For Docker users, here's the official Node.js image.
Troubleshooting for Windows:
If anyone gets file error 2502/2503 like myself during install, run the .msi via Administrator command prompt with command
msiexec /package [node msi]

The best way is to insert an appropriate input tag:
<input type="submit" value="submit" />
<form id="form-id">
<button id="your-id">submit</button>
</form>
var form = document.getElementById("form-id");
document.getElementById("your-id").addEventListener("click", function () {
form.submit();
});
Enclose the latter JavaScript code by an DOMContentLoaded
event (choose only load
for backward compatiblity) if you haven't already done so:
window.addEventListener("DOMContentLoaded", function () {
var form = document.... // copy the last code block!
});
Add an onclick
attribute to the link and an id
to the form:
<form id="form-id">
<a href="#" onclick="document.getElementById('form-id').submit();"> submit </a>
</form>
Whatever way you choose, you have call formObject.submit()
eventually (where formObject
is the DOM object of the <form>
tag).
You also have to bind such an event handler, which calls formObject.submit()
, so it gets called when the user clicked a specific link or button. There are two ways:
Recommended: Bind an event listener to the DOM object.
// 1. Acquire a reference to our <form>.
// This can also be done by setting <form name="blub">:
// var form = document.forms.blub;
var form = document.getElementById("form-id");
// 2. Get a reference to our preferred element (link/button, see below) and
// add an event listener for the "click" event.
document.getElementById("your-id").addEventListener("click", function () {
form.submit();
});
Not recommended: Insert inline JavaScript. There are several reasons why this technique is not recommendable. One major argument is that you mix markup (HTML) with scripts (JS). The code becomes unorganized and rather unmaintainable.
<a href="#" onclick="document.getElementById('form-id').submit();">submit</a>
<button onclick="document.getElementById('form-id').submit();">submit</button>
Now, we come to the point at which you have to decide for the UI element which triggers the submit() call.
A button
<button>submit</button>
A link
<a href="#">submit</a>
Apply the aforementioned techniques in order to add an event listener.

Apologies in advance for this lo-tech suggestion, but another option, which finally worked for me after battling NuGet for several hours, is to re-create a new empty project, Web API in my case, and just copy the guts of your old, now-broken project into the new one. Took me about 15 minutes.
You cannot use the Directory directive in .htaccess. However if you create a .htaccess file in the /system directory and place the following in it, you will get the same result

In my case the problem was that I had called $("#divDialog").removeData();
as part of resetting my forms data within the dialog.
This resulted in me wiping out a data structure named uiDialog
which meant that the dialog had to reinitialize.
I replaced .removeData()
with more specific deletes and everything started working again.
grep -R "somestring" | cut -d ":" -f 1
you might use default parameters in your function and then just pass the entire dataset itself, since the dataset is already a DOMStringMap Object
<div data-uid="aaa" data-name="bbb" data-value="ccc"
onclick="fun(this.dataset)">
<script>
const fun = ({uid:'ddd', name:'eee', value:'fff', other:'default'} = {}) {
//
}
</script>
that way, you can deal with any data-values that got set in the html tag, or use defaults if they weren't set - that kind of thing
maybe not in this situation, but in others, it might be advantageous to put all your preferences in a single data-attribute
<div data-all='{"uid":"aaa","name":"bbb","value":"ccc"}'
onclick="fun(JSON.parse(this.dataset.all))">
there are probably more terse ways of doing that, if you already know certain things about the order of the data
<div data-all="aaa,bbb,ccc" onclick="fun(this.dataset.all.split(','))">
I would suggest querying the sys
views. something similar to
SELECT *
FROM
sys.dm_exec_sessions s
LEFT JOIN sys.dm_exec_connections c
ON s.session_id = c.session_id
LEFT JOIN sys.dm_db_task_space_usage tsu
ON tsu.session_id = s.session_id
LEFT JOIN sys.dm_os_tasks t
ON t.session_id = tsu.session_id
AND t.request_id = tsu.request_id
LEFT JOIN sys.dm_exec_requests r
ON r.session_id = tsu.session_id
AND r.request_id = tsu.request_id
OUTER APPLY sys.dm_exec_sql_text(r.sql_handle) TSQL
This way you can get a TotalPagesAllocated
which can help you figure out the spid
that is taking all the server resources. There has lots of times when I can't even bring up activity monitor and use these sys
views to see what's going on.
I would recommend you reading the following article. I got this reference from here.
Parse the two dates firstDate

Pickle save:
try:
import cPickle as pickle
except ImportError: # Python 3.x
import pickle
with open('data.p', 'wb') as fp:
pickle.dump(data, fp, protocol=pickle.HIGHEST_PROTOCOL)
See the pickle module documentation for additional information regarding the protocol
argument.
Pickle load:
with open('data.p', 'rb') as fp:
data = pickle.load(fp)
JSON save:
import json
with open('data.json', 'w') as fp:
json.dump(data, fp)
Supply extra arguments, like sort_keys
or indent
, to get a pretty result. The argument sort_keys will sort the keys alphabetically and indent will indent your data structure with indent=N
spaces.
json.dump(data, fp, sort_keys=True, indent=4)
JSON load:
with open('data.json', 'r') as fp:
data = json.load(fp)
