Use setResizable on your JFrame
yourFrame.setResizable(false);
But extending JFrame is generally a bad idea.

\n didn't work for me. So I used <br></br>
HTML tag
<string name="message_register_success">

To show the div while selecting one value and hide while selecting another value from dropdown box: -
$('#yourselectorid').bind('change', function(event) {
var i= $('#yourselectorid').val();
if(i=="sometext") // equal to a selection option
{
$('#divid').show();
}
elseif(i=="othertext")
{
$('#divid').hide(); // hide the first one
$('#divid2').show(); // show the other one
}
});
transform: scale();
will make original element preserve its size.
I found the best option is to use vw
.
It's working like a charm:

Just a different way of listing/reading files from a jar URL and it does it recursively for nested jars
https://gist.github.com/trung/2cd90faab7f75b3bcbaa
URL urlResource = Thead.currentThread().getContextClassLoader().getResource("foo");
JarReader.read(urlResource, new InputStreamCallback() {
@Override
public void onFile(String name, InputStream is) throws IOException {
// got file name and content stream
}
});
If you want to set default value in terms of database, just set @Column( columnDefinition = "int default 1")
But if what you intend is to set a default value in your java app you can set it on your class attribute like this: private Integer attribute = 1;
The TextView resource id it needs is for a TextView layout file, so it won't be in the same activity.
You can create it by going to File > New > XML > XML Layout File, and enter the widget type, which is 'TextView' in the root tag field.

Here is a simple generic C++11 function contains
which works for both arrays and containers:
using namespace std;
template<class C, typename T>
bool contains(C&& c, T e) { return find(begin(c), end(c), e) != end(c); };
Simple usage contains(arr, el)
is somewhat similar to in
keyword semantics in Python.
Here is a complete demo:
#include <algorithm>
#include <array>
#include <string>
#include <vector>
#include <iostream>
template<typename C, typename T>
bool contains(C&& c, T e) {
return std::find(std::begin(c), std::end(c), e) != std::end(c);
};
template<typename C, typename T>
void check(C&& c, T e) {
std::cout << e << (contains(c,e) ? "" : " not") << " found\n";
}
int main() {
int a[] = { 10, 15, 20 };
std::array<int, 3> b { 10, 10, 10 };
std::vector<int> v { 10, 20, 30 };
std::string s { "Hello, Stack Overflow" };
check(a, 10);
check(b, 15);
check(v, 20);
check(s, 'Z');
return 0;
}
Output:
10 found
15 not found
20 found
Z not found
You should use finish()
when the user clicks on the button in order to go to the previous activity.
Button backButton = (Button)this.findViewById(R.id.back);
backButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
Alternatively, if you really need to, you can try to trigger your own back key press:
this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK));
this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
Execute both of these.
is there a way to pass param from
navigate.goback()
and parent can listen to the params and update its state?
You can pass a callback function as parameter (as mentioned in other answers).
Here is a more clear example, when you navigate from A to B and you want B to communicate information back to A you can pass a callback (here onSelect
):
ViewA.js
import React from "react";
import { Button, Text, View } from "react-native";
class ViewA extends React.Component {
state = { selected: false };
onSelect = data => {
this.setState(data);
};
onPress = () => {
this.props.navigate("ViewB", { onSelect: this.onSelect });
};
render() {
return (
<View>
<Text>{this.state.selected ? "Selected" : "Not Selected"}</Text>
<Button title="Next" onPress={this.onPress} />
</View>
);
}
}
ViewB.js
import React from "react";
import { Button } from "react-native";
class ViewB extends React.Component {
goBack() {
const { navigation } = this.props;
navigation.goBack();
navigation.state.params.onSelect({ selected: true });
}
render() {
return <Button title="back" onPress={this.goBack} />;
}
}
Hats off for debrice - Refer to https://github.com/react-navigation/react-navigation/issues/288#issuecomment-315684617
For React Navigation v5
ViewB.js
import React from "react";
import { Button } from "react-native";
class ViewB extends React.Component {
goBack() {
const { navigation, route } = this.props;
navigation.goBack();
route.params.onSelect({ selected: true });
}
render() {
return <Button title="back" onPress={this.goBack} />;
}
}
Writing record arrays as CSV files with headers requires a bit more work.
This example reads from a CSV file ('example.csv'
) and writes its contents to another CSV file (out.csv
).
import numpy as np
# Write an example CSV file with headers on first line
with open('example.csv', 'w') as fp:
fp.write('''\
col1,col2,col3
1,100.1,string1
2,222.2,second string
''')
# Read it as a Numpy record array
ar = np.recfromcsv('example.csv')
print(repr(ar))
# rec.array([(1, 100.1, 'string1'), (2, 222.2, 'second string')],
# dtype=[('col1', '<i4'), ('col2', '<f8'), ('col3', 'S13')])
# Write as a CSV file with headers on first line
with open('out.csv', 'w') as fp:
fp.write(','.join(ar.dtype.names) + '\n')
np.savetxt(fp, ar, '%s', ',')
Note that the above example cannot handle values which are strings with commas. To always enclose non-numeric values within quotes, use the csv
package:
import csv
with open('out2.csv', 'wb') as fp:
writer = csv.writer(fp, quoting=csv.QUOTE_NONNUMERIC)
writer.writerow(ar.dtype.names)
writer.writerows(ar.tolist())
The jQuery 2.2 and 1.12 Released post includes the following quote:
While jQuery is a HTML library, we agreed that class support for SVG elements could be useful. Users will now be able to call the .addClass(), .removeClass(), .toggleClass(), and .hasClass() methods on SVG. jQuery now changes the class attribute rather than the className property. This also makes the class methods usable in general XML documents. Keep in mind that many other things will not work with SVG, and we still recommend using a library dedicated to SVG if you need anything beyond class manipulation.
It tests:
If you click on that small square, it will change its color because the class
attribute is added / removed.
$("#x").click(function() {_x000D_
if ( $(this).hasClass("clicked") ) {_x000D_
$(this).removeClass("clicked");_x000D_

System.Data.SQLite.dll
is a mixed assembly, i.e. it contains both managed code and native code. Therefore a particular System.Data.SQLite.dll
is either x86 or x64, but never both.
Update (courtesy J. Pablo Fernandez): Cassini, the development web server used by Visual Studio when you press F5 or click the green «play» button, is x86 only which means that even if your workstation is x64, you'll only be able to use the x86 version of System.Data.SQLite.dll.
An alternative is not to use Cassini but IIS7 which is properly x64.
This suffices :
parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling || null);
since if the refnode
(second parameter) is null, a regular appendChild is performed. see here : http://reference.sitepoint.com/javascript/Node/insertBefore
Actually I doubt that the || null
is required, try it and see.
Based on mathematical concepts, I understand that:
n
, having 0
as remainder, are all multiples of n
Therefore, the following calculation also applies as a solution (multiples between 1 and 100):
>>> multiples_5 = [n for n in range(1, 101) if n % 5 == 0]
>>> multiples_5
[5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100]
For further reading:
You can directly return a different view like:
return View("NameOfView", Model);
Or you can make a partial view and can return like:
return PartialView("PartialViewName", Model);
In Kotlin language you can do it in this way:
val values = arrayOf(
"cat",
"dog",
"chicken"
)
ArrayAdapter(
this,
android.R.layout.simple_spinner_item,
values
).also {
it.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
spinner.adapter = it
}
What you can do to solve this is:

I'm on rails 5.2, and trying to rename a column on a devise User.
the rename_column
bit worked for me, but the singular :table_name
threw a "User table not found" error. Plural worked for me.
rails g RenameAgentinUser
Then change migration file to this:
rename_column :users, :agent?, :agent
Where :agent? is the old column name.
Go to you MainActivity.java
and below this code
-> NavigationView navigationView = findViewById(R.id.nav_view);
Add single line of code -> navigationView.setItemIconTintList(null);
i.e. the last line of my code
I hope this might solve your problem.
public class MainActivity extends AppCompatActivity {
private AppBarConfiguration mAppBarConfiguration;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setItemIconTintList(null);
You can use this to change tooltip-arrow color
.tooltip.bottom .tooltip-arrow {
top: 0;
left: 50%;
margin-left: -5px;
border-bottom-color: #000000; /* black */
border-width: 0 5px 5px;
}
If you use Firebug, you can use console.log to output an object and get a hyperlinked, explorable item in the console.
//
implements "floor division", regardless of your type. So
1.0/2.0
will give 0.5
, but both 1/2
, 1//2
and 1.0//2.0
will give 0
.
See https://docs.python.org/whatsnew/2.2.html#pep-238-changing-the-division-operator for details
I need to divide a list by a number and fixed like this.
l = [1,2,3,4,5,6]
def divideByN(data, n):
return [data[i*n : (i+1)*n] for i in range(len(data)//n)]
>>> print(divideByN(l,2))
[[1, 2], [3, 4], [5, 6]]
>>> print(divideByN(l,3))
[[1, 2, 3], [4, 5, 6]]
You ca also use Response.Write("alert('Error')");
Just adding some extra sorting if needed
=QUERY(A2:A,"select A, count(A) where A is not null group by A order by count(A) DESC label A 'Name', count(A) 'Count'",-1)
With a character class this big it is easier to say what you want to keep. A caret in the first position of a character class inverts its sense, so you can write
$varTemp =~ s/[^"%'+\-0-9<=>a-z_{|}]+//gi
or, using the more efficient tr
$varTemp =~ tr/"%'+\-0-9<=>A-Z_a-z{|}//cd
I made a jsben.ch for you http://jsben.ch/#/aWxtF ...seems that indexOf is a bit faster.
There is a simpler way simply disable the error handler in your error handler if it does not match the error types you are doing and resume.
The handler below checks agains each error type and if none are a match it returns error resume to normal VBA ie GoTo 0 and resumes the code which then tries to rerun the code and the normal error block pops up.
On Error GoTo ErrorHandler
x = 1/0
ErrorHandler:
if Err.Number = 13 then ' 13 is Type mismatch (only used as an example)
'error handling code for this
end if
If err.Number = 1004 then ' 1004 is Too Large (only used as an example)
'error handling code for this
end if
On Error GoTo 0
Resume
INSERT INTO `table` ( `data` , `date` ) VALUES('".$data."',NOW()+INTERVAL 1 DAY);
you can also try this
$("#clickable").click(function(event) {
var senderElementName = event.target.tagName.toLowerCase();
if(senderElementName === 'div')
{
// do something here
}
else
{
//do something with <a> tag
}
});
You may try this code for you to take comma separated values / an array of values to get back a JSON from webAPI
public class CategoryController : ApiController
{
public List<Category> Get(String categoryIDs)
{
List<Category> categoryRepo = new List<Category>();
String[] idRepo = categoryIDs.Split(',');
foreach (var id in idRepo)
{
categoryRepo.Add(new Category()
{
CategoryID = id,
CategoryName = String.Format("Category_{0}", id)
});
}
return categoryRepo;
}
}
public class Category
{
public String CategoryID { get; set; }
public String CategoryName { get; set; }
}
Output :
[
{"CategoryID":"4","CategoryName":"Category_4"},
{"CategoryID":"5","CategoryName":"Category_5"},
{"CategoryID":"3","CategoryName":"Category_3"}
]
I have used something like the following in C++ code before:
#include <sstream>
int main()
{
char* str = "1234";
std::stringstream s_str( str );
int i;
s_str >> i;
}
This plugin is documented rather good in https://polylang.wordpress.com/documentation.
The developers documentation states the following logic as a means to generate URL's for different translations of the same post
<?php while ( have_posts() ) : the_post(); ?>
<ul class='translations'><?php pll_the_languages(array('post_id' =>; $post->ID)); ?></ul>
<?php the_content(); ?>
<?php endwhile; ?>
If you want more influence on what is rendered, inspet pll_the_languages
function and copy it's behaviour to your own output implementation
As you want buttons to switch language, this page: https://polylang.wordpress.com/documentation/frequently-asked-questions/the-language-switcher/ will give you the required info.
An implementation example:
<ul><?php pll_the_languages();?></ul>
Then style with CSS to create buttons, flags or whatever you want. It is also possible to use a widget for this, provided by te plugin
All plugins functions are explained here: https://polylang.wordpress.com/documentation/documentation-for-developers/functions-reference/
In this case use:
pll_current_language();
In my case I have a Table Column name Path which datatype i set was varchar(200).After updating it to nvarchar(max), I have deleted the table from edmx and then again added the table and it wokred properly for me.
Just Go To *Startmenu >>Java >>Configure Java >> Security >> Edit site list >> copy and paste your Link with problem >> OK Problem fixed :)*
There is definitly a problem with the destination folder path.
Your above error message says, it wants to put the contents to a file in the directory /files/grantapps/
, which would be beyond your vhost
, but somewhere in the system (see the leading absolute slash )
You should double check:
/home/username/public_html/files/grantapps/
really present./home/username/public_html/files/grantapps/
<<~TEXT
Hi #{user.name},
Thanks for raising the flag, we're always happy to help you.
Your issue will be resolved within 2 hours.
Please be patient!
Thanks again,
Team #{user.organization.name}
TEXT
Theres a difference in <<-TEXT
and <<~TEXT
, former retains the spacing inside block and latter doesn't.
There are other options as well. Like concatenation etc. but this one makes more sense in general.
If I am wrong here, let me know how...
eg:
from: /xxx/a/b/c/d/e/1.html
to: user@remote:/pre_existing/dir/b/c/d/e/1.html
rsync:
cd /xxx/a/ && rsync -auvR b/c/d/e/ user@remote:/pre_existing/dir/
Here's how you might implement a counter:
counter=0
while true; do
if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
echo "Files Present" | mailx -s "File Present" -r [email protected] [email protected]
exit 0
elif [[ "$counter" -gt 20 ]]; then
echo "Counter: $counter times reached; Exiting loop!"
exit 1
else
counter=$((counter+1))
echo "Counter: $counter time(s); Sleeping for another half an hour" | mailx -s "Time to Sleep Now" -r [email protected] [email protected]
sleep 1800
fi
done
Some Explanations:
counter=$((counter+1))
- this is how you can increment a counter. The $
for counter
is optional inside the double parentheses in this case.elif [[ "$counter" -gt 20 ]]; then
- this checks whether $counter
is not greater than 20
. If so, it outputs the appropriate message and breaks out of your while loop.I think oracle is smart enough to convert the less efficient one (whichever that is) into the other. So I think the answer should rather depend on the readability of each (where I think that IN
clearly wins)
As an alternative to PHPMailer, Pear's Mail and others you could use the Zend's library
$config = array('auth' => 'login',
'ssl' => 'ssl',
'port'=> 465,
'username' => '[email protected]',
'password' => 'XXXXXXX');
$transport = new Zend_Mail_Transport_Smtp('smtp.gmail.com', $config);
$mail = new Zend_Mail();
$mail->setBodyText('This is the text of the mail.');
$mail->setFrom('[email protected]', 'Some Sender');
$mail->addTo('[email protected]', 'Some Recipient');
$mail->setSubject('TestSubj');
$mail->send($transport);
That is my set up in localhost server and I can able to see incoming mail to my mail box.

For JSON data, it's much easier to POST it as "application/json" content-type. If you use GET, you have to URL-encode the JSON in a parameter and it's kind of messy. Also, there is no size limit when you do POST. GET's size if very limited (4K at most).
You can use jQuery UI Dialog.
These libraries create HTML elements that look and behave like a dialog box, allowing you to put anything you want (including form elements or video) in the dialog.
This should get the id added.
ASP.NET MVC 5 and lower:
<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "signupform" }))
{ } %>
ASP.NET Core: You can use tag helpers in forms to avoid the odd syntax for setting the id.
<form asp-controller="Account" asp-action="Register" method="post" id="signupform" role="form"></form>
Recently it became possible (but with an odd workaround).
To do this you must first create text with the desired hyperlink in an editor that supports rich text formatting. This can be an advanced text editor, web browser, email client, web-development IDE, etc.). Then copypaste the text from the editor or rendered HTML from browser (or other). E.g. in the example below I copypasted the head of this StackOverflow page. As you may see, the hyperlink have been copied correctly and is clickable in the message (checked on Mac Desktop, browser, and iOS apps).
On Mac
I was able to compose the desired link in the native Pages app as shown below. When you are done, copypaste your text into Slack app. This is the probably easiest way on Mac OS.
On Windows
I have a strong suspicion that MS Word will do the same trick, but unfortunately I don't have an installed instance to check.
Universal
Create text in an online editor, such as Google Documents. Use Insert -> Link, modify the text and web URL, then copypaste into Slack.
jQuery has very limited array functions since JavaScript has most of them itself. But here are the ones they have: Utilities - jQuery API.
I got lucky and answered this in a comment to the question, but I'm posting a full answer for the sake of completeness and so we can mark this question as "Answered".
It depends on what you want to accomplish by sharing a controller; you can either share the same controller (though have different instances), or you can share the same controller instance.
Share a Controller
Two directives can use the same controller by passing the same method to two directives, like so:
app.controller( 'MyCtrl', function ( $scope ) {
// do stuff...
});
app.directive( 'directiveOne', function () {
return {
controller: 'MyCtrl'
};
});
app.directive( 'directiveTwo', function () {
return {
controller: 'MyCtrl'
};
});
Each directive will get its own instance of the controller, but this allows you to share the logic between as many components as you want.
Require a Controller
If you want to share the same instance of a controller, then you use require
.
require
ensures the presence of another directive and then includes its controller as a parameter to the link function. So if you have two directives on one element, your directive can require the presence of the other directive and gain access to its controller methods. A common use case for this is to require ngModel
.
^require
, with the addition of the caret, checks elements above directive in addition to the current element to try to find the other directive. This allows you to create complex components where "sub-components" can communicate with the parent component through its controller to great effect. Examples could include tabs, where each pane can communicate with the overall tabs to handle switching; an accordion set could ensure only one is open at a time; etc.
In either event, you have to use the two directives together for this to work. require
is a way of communicating between components.

var client = new TinyRestClient(new HttpClient(),"https://api.repustate.com/");
client.PostRequest("v2/demokey/score.json").

If later you commit, you will effectively create a new branch. Then you might continue working only on this branch or eventually merge the existing one into it.
Use the start command as follows.
start "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://www.google.com
It will be better to close chrome instances before you open a new one. You can do that as follows:
taskkill /IM chrome.exe
start "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://www.google.com
That'll work for you.
My approach is to make the track transparent. The scroll bar thumb color is #C1C1C1 to match the default scrollbar thumb color. You can make it anything you prefer :)
Try this:
html {
overflow-y: scroll;
}
body::-webkit-scrollbar {
width: 0.7em;
background-color: transparent;
}
body::-webkit-scrollbar-thumb {
background: #C1C1C1;
height:30px;
}
body::-webkit-scrollbar-track-piece
{
display:none;
}
Not straightforward, but it works:

The issue seems to be that you are adding the deffered.promise
when deffered
is itself the promise you should be adding:
Try changing to promises.push(deffered);
so you don't add the unwrapped promise to the array.
UploadService.uploadQuestion = function(questions){
var promises = [];
for(var i = 0 ; i < questions.length ; i++){
var deffered = $q.defer();
var question = questions[i];
$http({
url : 'upload/question',
method: 'POST',
data : question
}).
success(function(data){
deffered.resolve(data);
}).
error(function(error){
deffered.reject();
});
promises.push(deffered);
}
return $q.all(promises);
}
In my case removing node, delete all AppData/Roaming/npm and AppData/Roaming/npm-cache and installing node once again solve the issue.
Your code does work (tested with cpython 2.4, 2.5, 2.6, 2.7, 3.1 and 3.2):
>>> a = set(["Blah", "Hello"])
>>> a = list(a) # You probably wrote a = list(a()) here or list = set() above
>>> a
['Blah', 'Hello']
Check that you didn't overwrite list
by accident:
>>> assert list == __builtins__.list
You need to define a Remote Java Application in the Eclipse debug configurations:
Open the debug configurations (select project, then open from menu run/debug configurations) Select Remote Java Application in the left tree and press "New" button On the right panel select your web app project and enter 8787 in the port field. Here is a link to a detailed description of this process.
When you start the remote debug configuration Eclipse will attach to the JBoss process. If successful the debug view will show the JBoss threads. There is also a disconnect icon in the toolbar/menu to stop remote debugging.
The solution for me (openSUSE Leap 42.3, KDE) was to rename the folder ~/.gnupg
which apparently contained the cached keys and profiles.
After KDE logout/logon the ssh-add/agent is running again and the folder is created from scratch, but the old keys are all gone.
I didn't have success with the other approaches.
Use a list comprehension:
results = [int(i) for i in results]
e.g.
>>> results = ["1", "2", "3"]
>>> results = [int(i) for i in results]
>>> results
[1, 2, 3]
Step 1: Add the submodule
git submodule add git://some_repository.git some_repository
Step 2: Fix the submodule to a particular commit
By default the new submodule will be tracking HEAD of the master branch, but it will NOT be updated as you update your primary repository. In order to change the submodule to track a particular commit or different branch, change directory to the submodule folder and switch branches just like you would in a normal repository.
git checkout -b some_branch origin/some_branch
Now the submodule is fixed on the development branch instead of HEAD of master.

I'm not 100% sure this will work with Bootstrap but worth a try - it worked with Remodal.js which can be found on github: http://vodkabears.github.io/remodal/ and it would make sense for the methods to be pretty similar.
To stop the page jumping to the top and also prevent the right shift of content add a class to the body
when the modal is fired and set these CSS rules:
body.with-modal {
position: static;
height: auto;
overflow-y: hidden;
}
It's the position:static
and the height:auto
that combine to stop the jumping of content to the right. The overflow-y:hidden;
stops the page from being scrollable behind the modal.
Make sure that you work with the correct separator. I replaced all /
in a relative path with a File.separator
. This worked fine in the IDE, however did not work in the build JAR.
Well, one classic example is where you wanted to get a list of employees and their immediate managers:
select e.employee as employee, b.employee as boss
from emptable e, emptable b
where e.manager_id = b.empolyee_id
order by 1
It's basically used where there is any relationship between rows stored in the same table.
And so on...
There are situations where you can't use the (quite convincing) with... for...
structure. In that case, do the following:
line = self.fo.readline()
if len(line) != 0:
if 'str' in line:
break
This will work because the the readline()
leaves a trailing newline character, where as EOF is just an empty string.
I liked this question and some answers was helpful to me, but i need to convert the xml to one domination array, so i will post my solution maybe someone need it later:
<?php
$xml = json_decode(json_encode((array)simplexml_load_string($xml)),1);
$finalItem = getChild($xml);
var_dump($finalItem);
function getChild($xml, $finalItem = []){
foreach($xml as $key=>$value){
if(!is_array($value)){
$finalItem[$key] = $value;
}else{
$finalItem = getChild($value, $finalItem);
}
}
return $finalItem;
}
?>
Write it as a one-liner:
figure('position', [0, 0, 200, 500]) % create new figure with specified size
Since you mention ReSharper in a comment:
You can do this in ReSharper by using the "Goto File..." option (Ctrl-Shift-N or ReSharper -> Go To -> File...) in my key mappings.
A generic solution is to introduce a new type. It may be more involved, but it has the advantage of working for any type that doesn't define its own infinity.
If T
is a type for which lteq
is defined, you can define InfiniteOr<T>
with lteq
something like this:
class InfiniteOr with type parameter T:
field the_T of type null-or-an-actual-T
isInfinite()
return this.the_T == null
getFinite():
assert(!isInfinite());
return this.the_T
lteq(that)
if that.isInfinite()
return true
if this.isInfinite()
return false
return this.getFinite().lteq(that.getFinite())
I'll leave it to you to translate this to exact Java syntax. I hope the ideas are clear; but let me spell them out anyways.
The idea is to create a new type which has all the same values as some already existing type, plus one special value which—as far as you can tell through public methods—acts exactly the way you want infinity to act, e.g. it's greater than anything else. I'm using null
to represent infinity here, since that seems the most straightforward in Java.
If you want to add arithmetic operations, decide what they should do, then implement that. It's probably simplest if you handle the infinite cases first, then reuse the existing operations on finite values of the original type.
There might or might not be a general pattern to whether or not it's beneficial to adopt a convention of handling left-hand-side infinities before right-hand-side infinities or vice versa; I can't tell without trying it out, but for less-than-or-equal (lteq
) I think it's simpler to look at right-hand-side infinity first. I note that lteq
is not commutative, but add
and mul
are; maybe that is relevant.
Note: coming up with a good definition of what should happen on infinite values is not always easy. It is for comparison, addition and multiplication, but maybe not subtraction. Also, there is a distinction between infinite cardinal and ordinal numbers which you may want to pay attention to.

res = request.GET['paymentid']
will raise a KeyError
if paymentid
is not in the GET data.
Your sample php code checks to see if paymentid
is in the POST data, and sets $payID
to '' otherwise:
$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''
The equivalent in python is to use the get()
method with a default argument:
payment_id = request.POST.get('payment_id', '')
while debugging, this is what I see in the
response.GET: <QueryDict: {}>
,request.POST: <QueryDict: {}>
It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.
Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

You can install it by first extracting all the files from the ISO and then overwriting those files with the files from the ZIP. Then you can run the batch file as administrator to do the installation. Most of the packages install on windows 7, but I haven't tested yet how well they work.
You can easily achieve what you want using the appendix
package. Here's a sample file that shows you how. The key is the titletoc
option when calling the package. It takes whatever value you've defined in \appendixname
and the default value is Appendix
.
\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents
\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
\chapter{Consectetur adipiscing elit}
\chapter{Mauris euismod}
\end{appendices}
\end{document}
The output looks like
Another option is to use the case-insensitive flag i, then there's no need for the extra character range A-Z.
var reg = /^[a-z]+$/i;
console.log( reg.test("somethingELSE") ); //true
console.log( "somethingELSE".match(reg)[0] ); //"somethingELSE"
Here's a DEMO on how this regex works with test() and match().
Another way is to use an array as a type, e.g.:
Video[] videoArray = gson.fromJson(json, Video[].class);
This way you avoid all the hassle with the Type object, and if you really need a list you can always convert the array to a list, e.g.:
List<Video> videoList = Arrays.asList(videoArray);
IMHO this is much more readable.
In Kotlin this looks like this:
Gson().fromJson(jsonString, Array<Video>::class.java)
To convert this array into List, just use .toList()
method
After stumbling around, this worked for me:
df = df.astype(object).where(pd.notnull(df),None)
You can always use the DATALENGTH Function to determine if you have extra white space characters in text fields. This won't make the text visible but will show you where there are extra white space characters.
SELECT DATALENGTH('MyTextData ') AS BinaryLength, LEN('MyTextData ') AS TextLength
This will produce 11 for BinaryLength and 10 for TextLength.
In a table your SQL would like this:
SELECT *
FROM tblA
WHERE DATALENGTH(MyTextField) > LEN(MyTextField)
This function is usable in all versions of SQL Server beginning with 2005.
Type :h recording to learn more.
*q* *recording* q{0-9a-zA-Z"} Record typed characters into register {0-9a-zA-Z"} (uppercase to append). The 'q' command is disabled while executing a register, and it doesn't work inside a mapping. {Vi: no recording} q Stops recording. (Implementation note: The 'q' that stops recording is not stored in the register, unless it was the result of a mapping) {Vi: no recording} *@* @{0-9a-z".=*} Execute the contents of register {0-9a-z".=*} [count] times. Note that register '%' (name of the current file) and '#' (name of the alternate file) cannot be used. For "@=" you are prompted to enter an expression. The result of the expression is then executed. See also |@:|. {Vi: only named registers}
I normally use on
instead of click
. It allow me to add more events listeners to a specific function.
$(document).on("click touchend", ".class1, .class2, .class3", function () {
//do stuff
});
Depending on your applications, it might be easier to limit the memory the language interpreter uses. For example with Java you can set the amount of RAM the JVM will be allocated.

I understand this isn't what OP asked for, but I still think it is worth to point out how to do it with printf. I almost always prefer using it over std::cout (even with no previous C background).
printf("%.2X", a);
'2' defines the precision, 'X' or 'x' defines case.

As already mentioned if you can use await
. If you need to run the code synchronously like you mention .GetAwaiter().GetResult()
, .Result
or .Wait()
is a risk for deadlocks as many have said in comments/answers. Since most of us like oneliners you can use these for .Net 4.5<
Acquiring a value via an async method:
var result = Task.Run(() => asyncGetValue()).Result;
Syncronously calling an async method
Task.Run(() => asyncMethod()).Wait();
No deadlock issues will occur due to the use of Task.Run
.

Update:
Could cause a deadlock if the calling thread is from the threadpool. The following happens: A new task is queued to the end of the queue, and the threadpool thread which would eventually execute the Task is blocked until the Task is executed.

this question asked in 2009 but i want to share my codes:
Public Function RowSearch(ByVal dttable As DataTable, ByVal searchcolumns As String()) As DataTable
Dim x As Integer
Dim y As Integer
Dim bln As Boolean
Dim dttable2 As New DataTable
For x = 0 To dttable.Columns.Count - 1
dttable2.Columns.Add(dttable.Columns(x).ColumnName)
Next
For x = 0 To dttable.Rows.Count - 1
For y = 0 To searchcolumns.Length - 1
If String.IsNullOrEmpty(searchcolumns(y)) = False Then
If searchcolumns(y) = CStr(dttable.Rows(x)(y + 1) & "") & "" Then
bln = True
Else
bln = False
Exit For
End If
End If
Next
If bln = True Then
dttable2.Rows.Add(dttable.Rows(x).ItemArray)
End If
Next
Return dttable2
End Function
If you only have Y to send :
$> yes Y |./your_script
If you only have N to send :
$> yes N |./your_script
yield in python is in a way similar to the return statement, except for some differences. If multiple values have to be returned from a function, return statement will return all the values as a list and it has to be stored in the memory in the caller block. But what if we don't want to use extra memory? Instead, we want to get the value from the function when we need it. This is where yield comes in. Consider the following function :-
def fun():
yield 1
yield 2
yield 3
And the caller is :-
def caller():
print ('First value printing')
print (fun())
print ('Second value printing')
print (fun())
print ('Third value printing')
print (fun())
The above code segment (caller function) when called, outputs :-
First value printing
1
Second value printing
2
Third value printing
3
As can be seen from above, yield returns a value to its caller, but when the function is called again, it doesn't start from the first statement, but from the statement right after the yield. In the above example, "First value printing" was printed and the function was called. 1 was returned and printed. Then "Second value printing" was printed and again fun() was called. Instead of printing 1 (the first statement), it returned 2, i.e., the statement just after yield 1. The same process is repeated further.
You need to add a reference inside the window tag. Something like:
xmlns:controls="clr-namespace:YourCustomNamespace.Controls;assembly=YourAssemblyName"
(When you add xmlns:controls=" intellisense should kick in to make this bit easier)
Then you can add the control with:
<controls:CustomControlClassName ..... />
I got a simple fix to this by casting the lists into strings and performing string operations to get the proper print out of the matrix.
By creating a function, it saves you the trouble of writing the for
loop every time you want to print out a matrix.
def print_matrix(matrix):
for row in matrix:
new_row = str(row)
new_row = new_row.replace(',','')
new_row = new_row.replace('[','')
new_row = new_row.replace(']','')
print(new_row)
Example of a 5x5 matrix with 0
as every entry:
>>> test_matrix = [[0] * 5 for i in range(5)]
>>> print_matrix(test_matrix)
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
Example of a 2x3 matrix with 0
as every entry:
>>> test_matrix = [[0] * 3 for i in range(2)]
>>> print_matrix(test_matrix)
0 0 0
0 0 0
If you want to make it print:
A A A A A
B B B B B
C C C C C
D D D D D
E E E E E
I suggest you just change the way you enter your data into your lists within lists. In my method, each list within the larger list represents a line in the matrix, not columns.
Its Ctrl + Shift + r
For me, there was only one option to discard all.
jimmyorr's answer does not work on Windows. it helps to use --not
instead of ^
like so:
git log oldbranch --not newbranch --no-merges
Use commas to separate case
switch (pageid)
{
case "listing-page","home-page":
alert("hello");
break;
case "details-page":
alert("goodbye");
break;
}
A raw-type is the a lack of a type parameter when using a generic type.
Raw-type should not be used because it could cause runtime errors, like inserting a double
into what was supposed to be a Set
of int
s.
Set set = new HashSet();
set.add(3.45); //ok
When retrieving the stuff from the Set
, you don't know what is coming out. Let's assume that you expect it to be all int
s, you are casting it to Integer
; exception at runtime when the double
3.45 comes along.
With a type parameter added to your Set
, you will get a compile error at once. This preemptive error lets you fix the problem before something blows up during runtime (thus saving on time and effort).
Set<Integer> set = new HashSet<Integer>();
set.add(3.45); //NOT ok.
I had the requirement to retrieve all properties whose key starts with a distinct prefix (e.g. all properties starting with "log4j.appender.") and wrote following Code (using streams and lamdas of Java 8).
public static Map<String,Object> getPropertiesStartingWith( ConfigurableEnvironment aEnv,
String aKeyPrefix )
{
Map<String,Object> result = new HashMap<>();
Map<String,Object> map = getAllProperties( aEnv );
for (Entry<String, Object> entry : map.entrySet())
{
String key = entry.getKey();
if ( key.startsWith( aKeyPrefix ) )
{
result.put( key, entry.getValue() );
}
}
return result;
}
public static Map<String,Object> getAllProperties( ConfigurableEnvironment aEnv )
{
Map<String,Object> result = new HashMap<>();
aEnv.getPropertySources().forEach( ps -> addAll( result, getAllProperties( ps ) ) );
return result;
}
public static Map<String,Object> getAllProperties( PropertySource<?> aPropSource )
{
Map<String,Object> result = new HashMap<>();
if ( aPropSource instanceof CompositePropertySource)
{
CompositePropertySource cps = (CompositePropertySource) aPropSource;
cps.getPropertySources().forEach( ps -> addAll( result, getAllProperties( ps ) ) );
return result;
}
if ( aPropSource instanceof EnumerablePropertySource<?> )
{
EnumerablePropertySource<?> ps = (EnumerablePropertySource<?>) aPropSource;
Arrays.asList( ps.getPropertyNames() ).forEach( key -> result.put( key, ps.getProperty( key ) ) );
return result;
}
// note: Most descendants of PropertySource are EnumerablePropertySource. There are some
// few others like JndiPropertySource or StubPropertySource
myLog.debug( "Given PropertySource is instanceof " + aPropSource.getClass().getName()
+ " and cannot be iterated" );
return result;
}
private static void addAll( Map<String, Object> aBase, Map<String, Object> aToBeAdded )
{
for (Entry<String, Object> entry : aToBeAdded.entrySet())
{
if ( aBase.containsKey( entry.getKey() ) )
{
continue;
}
aBase.put( entry.getKey(), entry.getValue() );
}
}
Note that the starting point is the ConfigurableEnvironment which is able to return the embedded PropertySources (the ConfigurableEnvironment is a direct descendant of Environment). You can autowire it by:
@Autowired
private ConfigurableEnvironment myEnv;
If you not using very special kinds of property sources (like JndiPropertySource, which is usually not used in spring autoconfiguration) you can retrieve all properties held in the environment.
The implementation relies on the iteration order which spring itself provides and takes the first found property, all later found properties with the same name are discarded. This should ensure the same behaviour as if the environment were asked directly for a property (returning the first found one).
Note also that the returned properties are not yet resolved if they contain aliases with the ${...} operator. If you want to have a particular key resolved you have to ask the Environment directly again:
myEnv.getProperty( key );
Json.NET has a JsonPropertyAttribute
which allows you to specify the name of a JSON property, so your code should be:
public class TeamScore
{
[JsonProperty("eighty_min_score")]
public string EightyMinScore { get; set; }
[JsonProperty("home_or_away")]
public string HomeOrAway { get; set; }
[JsonProperty("score ")]
public string Score { get; set; }
[JsonProperty("team_id")]
public string TeamId { get; set; }
}
public class Team
{
public string v1 { get; set; }
[JsonProperty("attributes")]
public TeamScore TeamScores { get; set; }
}
public class RootObject
{
public List<Team> Team { get; set; }
}
Documentation: Serialization Attributes
f = open("file.txt")
lines = f.readlines()
Look over here. readlines()
returns a list containing one line per element. Note that these lines contain the \n
(newline-character) at the end of the line. You can strip off this newline-character by using the strip()
-method. I.e. call lines[index].strip()
in order to get the string without the newline character.
As joaquin noted, do not forget to f.close()
the file.
Converting strint to integers is easy: int("12")

SHIFT + Page Up
and SHIFT + Page Down
are the correct keys to operate on the linux (virtual) console, but vmware console doesn't have those terminal settings. The virtual console has fixed scroll back size, it sounds like it's limited to video memory size according to this Linux virtual console Scrolling behavior documentation.
This is possible with window.localStorage
or window.sessionStorage
. The difference is that sessionStorage
lasts for as long as the browser stays open, localStorage
survives past browser restarts. The persistence applies to the entire web site not just a single page of it.
When you need to set a variable that should be reflected in the next page(s), use:
var someVarName = "value";
localStorage.setItem("someVarKey", someVarName);
And in any page (like when the page has loaded), get it like:
var someVarName = localStorage.getItem("someVarKey");
.getItem()
will return null
if no value stored, or the value stored.
Note that only string values can be stored in this storage, but this can be overcome by using JSON.stringify
and JSON.parse
. Technically, whenever you call .setItem()
, it will call .toString()
on the value and store that.
MDN's DOM storage guide (linked below), has workarounds/polyfills, that end up falling back to stuff like cookies, if localStorage
isn't available.
It wouldn't be a bad idea to use an existing, or create your own mini library, that abstracts the ability to save any data type (like object literals, arrays, etc.).

A few comments:
analog=True

, and you should use scipy.signal.freqz
(not freqs
) to generate the frequency response.Here's my modified version of your script, followed by the plot that it generates.

nyq = 0.5 * fs
normal_cutoff = cutoff / nyq
b, a = butter(order, normal_cutoff, btype='low', analog=False)
return b, a
def butter_lowpass_filter(data, cutoff, fs, order=5):
b, a = butter_lowpass(cutoff, fs, order=order)
y = lfilter(b, a, data)
return y
# Filter requirements.
order = 6
fs = 30.0 # sample rate, Hz
cutoff = 3.667 # desired cutoff frequency of the filter, Hz
# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)
# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')

# "Noisy" data. We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

Laravel 7.x and above has added new method to paginator:
->withQueryString()
So you can use it like:
{{ $users->withQueryString()->links() }}
For laravel below 7.x use:
{{ $users->appends(request()->query())->links() }}
On Windows 8.1 using CMDER, I created the ssh key with this file path /c/Users/youruser/.ssh/id_rsa_whatever, the problem was the : that I was using. With this path I didn't create the folder before running the command, there is no need to run mkdir because the command will create the folder automatically.
Many people will suggest you use MERGE
, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:
http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/
Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;
A lot of folks will suggest this way:
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
UPDATE ...
END
ELSE
BEGIN
INSERT ...
END
COMMIT TRANSACTION;
But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)
Others will suggest this way:
BEGIN TRY
INSERT ...
END TRY
BEGIN CATCH
IF ERROR_NUMBER() = 2627
UPDATE ...
END CATCH
However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:
Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE
is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.
This will print everything after each match, on that same line only:
perl -lne 'print $1 if /^potato:\s*(.*)/' file.txt
This will do the same, except it will also print all subsequent lines:
perl -lne 'if ($found){print} elsif (/^potato:\s*(.*)/){print $1; $found++}' file.txt
These command-line options are used:
-n
loop around each line of the input file-l
removes newlines before processing, and adds them back in afterwards -e
execute the perl code One thing to note is that the two are actually very related. Linear SVMs are equivalent to single-layer NN's (i.e., perceptrons), and multi-layer NNs can be expressed in terms of SVMs. See here for some details.
If you are using Razor, you cannot access the field directly, but you can manage its value.
The idea is that the first Microsoft approach drive the developers away from Web Development and make it easy for Desktop programmers (for example) to make web applications.
Meanwhile, the web developers, did not understand this tricky strange way of ASP.NET.
Actually this hidden input is rendered on client-side, and the ASP has no access to it (it never had). However, in time you will see its a piratical way and you may rely on it, when you get use with it. The web development differs from the Desktop or Mobile.
The model is your logical unit, and the hidden field (and the whole view page) is just a representative view of the data. So you can dedicate your work on the application or domain logic and the view simply just serves it to the consumer - which means you need no detailed access and "brainstorming" functionality in the view.
The controller actually does work you need for manage the hidden or general setup. The model serves specific logical unit properties and functionality and the view just renders it to the end user, simply said. Read more about MVC.
Model
public class MyClassModel
{
public int Id { get; set; }
public string Name { get; set; }
public string MyPropertyForHidden { get; set; }
}
This is the controller aciton
public ActionResult MyPageView()
{
MyClassModel model = new MyClassModel(); // Single entity, strongly-typed
// IList model = new List<MyClassModel>(); // or List, strongly-typed
// ViewBag.MyHiddenInputValue = "Something to pass"; // ...or using ViewBag
return View(model);
}
The view is below
//This will make a Model property of the View to be of MyClassModel
@model MyNamespace.Models.MyClassModel // strongly-typed view
// @model IList<MyNamespace.Models.MyClassModel> // list, strongly-typed view
// ... Some Other Code ...
@using(Html.BeginForm()) // Creates <form>
{
// Renders hidden field for your model property (strongly-typed)
// The field rendered to server your model property (Address, Phone, etc.)
Html.HiddenFor(model => Model.MyPropertyForHidden);
// For list you may use foreach on Model
// foreach(var item in Model) or foreach(MyClassModel item in Model)
}
// ... Some Other Code ...
The view with ViewBag:
// ... Some Other Code ...
@using(Html.BeginForm()) // Creates <form>
{
Html.Hidden(
"HiddenName",
ViewBag.MyHiddenInputValue,
new { @class = "hiddencss", maxlength = 255 /*, etc... */ }
);
}
// ... Some Other Code ...
We are using Html Helper to render the Hidden field or we could write it by hand - <input name=".." id=".." value="ViewBag.MyHiddenInputValue">
also.
The ViewBag is some sort of data carrier to the view. It does not restrict you with model - you can place whatever you like.

I know this answer violates the terms of your question, but I think the correct answer to your intent is simply this: use whichever algorithm allows you the longest key length, then make sure you choose a really good key. Minor differences in the performance of most well regarded algorithms (cryptographically and chronologically) are overwhelmed by a few extra bits of a key.
Collection c;
Iterator iter = c.iterator();
Object first = iter.next();
(This is the closest you'll get to having the "first" element of a Set
. You should realize that it has absolutely no meaning for most implementations of Set
. This may have meaning for LinkedHashSet and TreeSet, but not for HashSet.)
If you are ok using an external plugin to do that you can use Header and Footer Scripts plugin
From the description:
Many WordPress Themes do not have any options to insert header and footer scripts in your site or . It helps you to keep yourself from theme lock. But, sometimes it also causes some pain for many. like where should I insert Google Analytics code (or any other web-analytics codes). This plugin is one stop and lightweight solution for that. With this "Header and Footer Script" plugin will be able to inject HTML tags, JS and CSS codes to and easily.
Maybe you wrongly set permission on python3. For instance if for the file permission is set like
`os.chmod('spam.txt', 0777)` --> This will lead to SyntaxError
This syntax was used in Python2. Now if you change like:
os.chmod('spam.txt', 777)
--> This is still worst!! Your permission will be set wrongly since are not on "octal" but on decimal.
Afterwards you will get permission Error if you try for instance to remove the file: PermissionError: [WinError 5] Access is denied:
Solution for python3 is quite easy:
os.chmod('spam.txt', 0o777)
--> The syntax is now ZERO and o "0o"
You should use some HTML parsing library like lxml
:
from lxml import etree
s = """<table>
<tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
<tr><td>a</td><td>b</td><td>c</td></tr>
<tr><td>d</td><td>e</td><td>f</td></tr>
<tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""
table = etree.HTML(s).find("body/table")
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
values = [col.text for col in row]
print dict(zip(headers, values))
prints
{'End Date': 'c', 'Start Date': 'b', 'Event': 'a'}
{'End Date': 'f', 'Start Date': 'e', 'Event': 'd'}
{'End Date': 'i', 'Start Date': 'h', 'Event': 'g'}
Use:
List<String> x = new ArrayList<>(Arrays.asList("xyz", "abc"));
If you don't want to add new elements to the list later, you can also use (Arrays.asList returns a fixed-size list):
List<String> x = Arrays.asList("xyz", "abc");
Note: you can also use a static import if you like, then it looks like this:
import static java.util.Arrays.asList;
...
List<String> x = new ArrayList<>(asList("xyz", "abc"));
or
List<String> x = asList("xyz", "abc");
I had this problem and I was able to fix this by updating npm
sudo npm update -g npm
Before the update, the result of npm info graceful-fs | grep 'version:'
was:
version: '3.3.12'
After the update the result is:
version: '3.9.3'
If you are insisting to use the window.location.origin
You can put this in top of your code before reading the origin
if (!window.location.origin) {
window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
}
PS: For the record, it was actually the original question. It was already edited :)
i++ is known as Post Increment whereas ++i is called Pre Increment.
i++
i++
is post increment because it increments i
's value by 1 after the operation is over.
Lets see the following example:
int i = 1, j;
j = i++;
Here value of j = 1
but i = 2
. Here value of i
will be assigned to j
first then i
will be incremented.
++i
++i
is pre increment because it increments i
's value by 1 before the operation.
It means j = i;
will execute after i++
.
Lets see the following example:
int i = 1, j;
j = ++i;
Here value of j = 2
but i = 2
. Here value of i
will be assigned to j
after the i
incremention of i
.
Similarly ++i
will be executed before j=i;
.
For your question which should be used in the incrementation block of a for loop? the answer is, you can use any one.. doesn't matter. It will execute your for loop same no. of times.
for(i=0; i<5; i++)
printf("%d ",i);
And
for(i=0; i<5; ++i)
printf("%d ",i);
Both the loops will produce same output. ie 0 1 2 3 4
.
It only matters where you are using it.
for(i = 0; i<5;)
printf("%d ",++i);
In this case output will be 1 2 3 4 5
.
use only
base64.b64decode(a)
instead of
base64.b64decode(a).decode('utf-8')

Like most things "it depends". It's not right or wrong/good or bad in and of itself to store data in columns or JSON. It depends on what you need to do with it later. What is your predicted way of accessing this data? Will you need to cross reference other data?
Other people have answered pretty well what the technical trade-off are.
Not many people have discussed that your app and features evolve over time and how this data storage decision impacts your team.
Because one of the temptations of using JSON is to avoid migrating schema and so if the team is not disciplined, it's very easy to stick yet another key/value pair into a JSON field. There's no migration for it, no one remembers what it's for. There is no validation on it.
My team used JSON along side traditional columns in postgres and at first it was the best thing since sliced bread. JSON was attractive and powerful, until one day we realized that flexibility came at a cost and it's suddenly a real pain point. Sometimes that point creeps up really quickly and then it becomes hard to change because we've built so many other things on top of this design decision.
Overtime, adding new features, having the data in JSON led to more complicated looking queries than what might have been added if we stuck to traditional columns. So then we started fishing certain key values back out into columns so that we could make joins and make comparisons between values. Bad idea. Now we had duplication. A new developer would come on board and be confused? Which is the value I should be saving back into? The JSON one or the column?
The JSON fields became junk drawers for little pieces of this and that. No data validation on the database level, no consistency or integrity between documents. That pushed all that responsibility into the app instead of getting hard type and constraint checking from traditional columns.
Looking back, JSON allowed us to iterate very quickly and get something out the door. It was great. However after we reached a certain team size it's flexibility also allowed us to hang ourselves with a long rope of technical debt which then slowed down subsequent feature evolution progress. Use with caution.
Think long and hard about what the nature of your data is. It's the foundation of your app. How will the data be used over time. And how is it likely TO CHANGE?
I think many of the answers here may be missing a quality method included in StringBuilder
: .delete(int start, [int] end)
. I know this is a late reply; however, this should be made known (and explained a bit more thoroughly).
Let's say you have a StringBuilder table - which you wish to modify, dynamically, throughout your program (one I am working on right now does this), e.g.
StringBuilder table = new StringBuilder();
If you are looping through the method and alter the content, use the content, then wish to discard the content to "clean up" the StringBuilder
for the next iteration, you can delete it's contents, e.g.
table.delete(int start, int end).
start and end being the indices of the chars you wish to remove. Don't know the length in chars and want to delete the whole thing?
table.delete(0, table.length());
NOW, for the kicker. StringBuilders
, as mentioned previously, take a lot of overhead when altered frequently (and can cause safety issues with regard to threading); therefore, use StringBuffer
- same as StringBuilder
(with a few exceptions) - if your StringBuilder
is used for the purpose of interfacing with the user.
A lot answers here recommends $@
or $*
with and without quotes, however none seems to explain what these really do and why you should that way. So let me steal this excellent summary from this answer:
+--------+---------------------------+
| Syntax | Effective result |
+--------+---------------------------+
| $* | $1 $2 $3 ... ${N} |
+--------+---------------------------+
| $@ | $1 $2 $3 ... ${N} |
+--------+---------------------------+
| "$*" | "$1c$2c$3c...c${N}" |
+--------+---------------------------+
| "$@" | "$1" "$2" "$3" ... "${N}" |
+--------+---------------------------+
Notice that quotes makes all the difference and without them both have identical behavior.
For my purpose, I needed to pass parameters from one script to another as-is and for that the best option is:
# file: parent.sh
# we have some params passed to parent.sh
# which we will like to pass on to child.sh as-is
./child.sh $*
Notice no quotes and $@
should work as well in above situation.
What version of mySQL are you using? I''m using 5.7.10 and had the same problem with logging on as root
There is 2 issues - why can't I log in as root to start with, and why can I not use 'mysqld_safe` to start mySQL to reset the root password.
I have no answer to setting up the root password during installation, but here's what you do to reset the root password
Edit the initial root password on install can be found by running
grep 'temporary password' /var/log/mysqld.log
http://dev.mysql.com/doc/refman/5.7/en/linux-installation-yum-repo.html
systemd
is now used to look after mySQL instead of mysqld_safe
(which is why you get the -bash: mysqld_safe: command not found
error - it's not installed)
The user
table structure has changed.
So to reset the root password, you still start mySQL with --skip-grant-tables
options and update the user
table, but how you do it has changed.
1. Stop mysql:
systemctl stop mysqld
2. Set the mySQL environment option
systemctl set-environment MYSQLD_OPTS="--skip-grant-tables"
3. Start mysql usig the options you just set
systemctl start mysqld
4. Login as root
mysql -u root
5. Update the root user password with these mysql commands
mysql> UPDATE mysql.user SET authentication_string = PASSWORD('MyNewPassword')
-> WHERE User = 'root' AND Host = 'localhost';
mysql> FLUSH PRIVILEGES;
mysql> quit
*** Edit ***
As mentioned my shokulei in the comments, for 5.7.6 and later, you should use
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
Or you'll get a warning
6. Stop mysql
systemctl stop mysqld
7. Unset the mySQL envitroment option so it starts normally next time
systemctl unset-environment MYSQLD_OPTS
8. Start mysql normally:
systemctl start mysqld
Try to login using your new password:
7. mysql -u root -p
Reference
As it says at http://dev.mysql.com/doc/refman/5.7/en/mysqld-safe.html,
Note
As of MySQL 5.7.6, for MySQL installation using an RPM distribution, server startup and shutdown is managed by systemd on several Linux platforms. On these platforms, mysqld_safe is no longer installed because it is unnecessary. For more information, see Section 2.5.10, “Managing MySQL Server with systemd”.
Which takes you to http://dev.mysql.com/doc/refman/5.7/en/server-management-using-systemd.html where it mentions the systemctl set-environment MYSQLD_OPTS=
towards the bottom of the page.
The password reset commands are at the bottom of http://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html
Based on the answer by elysch, here is a solution for multiple schemas:
DO $$
DECLARE
r record;
i int;
v_schema text[] := '{public,schema1,schema2,schema3}';
v_new_owner varchar := 'my_new_owner';
BEGIN
FOR r IN
select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = ANY (v_schema)
union all
select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = ANY (v_schema)
union all
select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = ANY (v_schema)
union all
select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = ANY (v_schema)
union all
select 'ALTER DATABASE "' || current_database() || '" OWNER TO ' || v_new_owner
LOOP
EXECUTE r.a;
END LOOP;
FOR i IN array_lower(v_schema,1) .. array_upper(v_schema,1)
LOOP
EXECUTE 'ALTER SCHEMA "' || v_schema[i] || '" OWNER TO ' || v_new_owner ;
END LOOP;
END

There are actually several ways to import an excel file in to a MySQL database with varying degrees of complexity and success.
Excel2MySQL. Hands down, the easiest and fastest way to import Excel data into MySQL. It supports all verions of Excel and doesn't require Office install.
LOAD DATA INFILE: This popular option is perhaps the most technical and requires some understanding of MySQL command execution. You must manually create your table before loading and use appropriately sized VARCHAR field types. Therefore, your field data types are not optimized. LOAD DATA INFILE has trouble importing large files that exceed 'max_allowed_packet' size. Special attention is required to avoid problems importing special characters and foreign unicode characters. Here is a recent example I used to import a csv file named test.csv.
phpMyAdmin: Select your database first, then select the Import tab. phpMyAdmin will automatically create your table and size your VARCHAR fields, but it won't optimize the field types. phpMyAdmin has trouble importing large files that exceed 'max_allowed_packet' size.
MySQL for Excel: This is a free Excel Add-in from Oracle. This option is a bit tedious because it uses a wizard and the import is slow and buggy with large files, but this may be a good option for small files with VARCHAR data. Fields are not optimized.
copy your Json and paste at textbox on http://json2csharp.com/ and click on Generate button,
A cs class will be generated use that cs file as below:
var generatedcsResponce = JsonConvert.DeserializeObject(yourJson);
where RootObject is the name of the generated cs file;
Dumping without using output.
mysqldump --no-data <database name> --result-file=schema.sql
As mentioned earlier.
sudo rm -rf /usr/local/lib/node_modules/npm
brew uninstall --force node
brew install node
If the solution above doesn't work for anyone. Give this a try as well
a {
box-shadow: none;
}
No such function exists or is possible to write.
The problem is the edge case Integer.MIN_VALUE (-2,147,483,648 = 0x80000000) apply each of the three methods above and you get the same value out. This is due to the representation of integers and the maximum possible integer Integer.MAX_VALUE (-2,147,483,647 = 0x7fffffff) which is one less what -Integer.MIN_VALUE should be.
Use indexOf
var url = "http://mysite.com/somedir/somefile/?aa";
if (url.indexOf("?")>-1){
url = url.substr(0,url.indexOf("?"));
}
this is my solution when we want to calculate a date given year, week number and day of the week.
int Year = 2014;
int Week = 48;
int DayOfWeek = 4;
DateTime FecIni = new DateTime(Year, 1, 1);
FecIni = FecIni.AddDays(7 * (Week - 1));
if ((int)FecIni.DayOfWeek > DayOfWeek)
{
while ((int)FecIni.DayOfWeek != DayOfWeek) FecIni = FecIni.AddDays(-1);
}
else
{
while ((int)FecIni.DayOfWeek != DayOfWeek) FecIni = FecIni.AddDays(1);
}
Whoa. You're really over-complicating it by a very long distance. Try:
>>> print hex(0x12ef ^ 0xabcd)
0xb922
You seem to be ignoring these handy facts, at least:
0x
prefix.hex()
function can be used to convert any number into a hexadecimal string for display.If you already have the numbers as strings, you can use the int()
function to convert to numbers, by providing the expected base (16 for hexadecimal numbers):
>>> print int("12ef", 16)
4874
So you can do two conversions, perform the XOR, and then convert back to hex:
>>> print hex(int("12ef", 16) ^ int("abcd", 16))
0xb922
Taken from here - Introduction to Time Complexity of an Algorithm
In computer science, the time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the length of the string representing the input.
The time complexity of an algorithm is commonly expressed using big O notation, which excludes coefficients and lower order terms. When expressed this way, the time complexity is said to be described asymptotically, i.e., as the input size goes to infinity.
For example, if the time required by an algorithm on all inputs of size n is at most 5n3 + 3n, the asymptotic time complexity is O(n3). More on that later.
Few more Examples:
An algorithm is said to run in constant time if it requires the same amount of time regardless of the input size.
Examples:
An algorithm is said to run in linear time if its time execution is directly proportional to the input size, i.e. time grows linearly as input size increases.
Consider the following examples, below I am linearly searching for an element, this has a time complexity of O(n).
int find = 66;
var numbers = new int[] { 33, 435, 36, 37, 43, 45, 66, 656, 2232 };
for (int i = 0; i < numbers.Length - 1; i++)
{
if(find == numbers[i])
{
return;
}
}
More Examples:
An algorithm is said to run in logarithmic time if its time execution is proportional to the logarithm of the input size.
Example: Binary Search
Recall the "twenty questions" game - the task is to guess the value of a hidden number in an interval. Each time you make a guess, you are told whether your guess is too high or too low. Twenty questions game implies a strategy that uses your guess number to halve the interval size. This is an example of the general problem-solving method known as binary search
An algorithm is said to run in quadratic time if its time execution is proportional to the square of the input size.
Examples:
For cases like this, the effect is the same: You end up passing the address of the first character in a string of characters.
The declarations are obviously not the same though.
The following sets aside memory for a string and also a character pointer, and then initializes the pointer to point to the first character in the string.
char *p = "hello";
While the following sets aside memory just for the string. So it can actually use less memory.
char p[10] = "hello";
You may just without making the element hidden, simply make it transparent by making its opacity to 0.
Making the input file hidden will make it STOP working. So DON'T DO THAT..
Here you can find an example for a transparent Browse operation;
For swedish Å Ä Ö the only solution form the ones above working was:

Completely reset?
Delete the .git
directory locally.
Recreate the git repostory:
$ cd (project-directory)
$ git init
$ (add some files)
$ git add .
$ git commit -m 'Initial commit'
Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.
$ git remote add origin <url>
$ git push --force --set-upstream origin master
Well, no. Why there should be? Just discard the string if you don't need it anymore.
&str
is more useful than String
when you need to only read a string, because it is only a view into the original piece of data, not its owner. You can pass it around more easily than String
, and it is copyable, so it is not consumed by the invoked methods. In this regard it is more general: if you have a String
, you can pass it to where an &str
is expected, but if you have &str
, you can only pass it to functions expecting String
if you make a new allocation.
You can find more on the differences between these two and when to use them in the official strings guide.
I need to click the link who's href has substring "long" in it. How can I do this?
With the beauty of CSS selectors.
your statement would be...
driver.findElement(By.cssSelector("a[href*='long']")).click();
This means, in english,
Find me any 'a' elements, that have the
href
attribute, and that attributecontains
'long'
You can find a useful article about formulating your own selectors for automation effectively, as well as a list of all the other equality operators. contains
, starts with
, etc... You can find that at: http://ddavison.io/css/2014/02/18/effective-css-selectors.html
The last argument of CONVERT
seems to determine the format used for parsing. Consult MSDN docs for CONVERT.
111
- the one you are using is Japan yy/mm/dd
.
I guess the one you are looking for is 103
, that is dd/mm/yyyy
.
So you should try:
SELECT convert(datetime, '23/07/2009', 103)
Another option, if you're using temporary tables instead of staging tables, could be to create the temporary table as your import expects, then add the identity column after the import.
So your sql does something like this:
Still not very clean, but it's another option... might have to get locks to be safe, too.
If you have not set the type of a file, Git tries to determine it automatically and a file with really long lines and maybe some wide characters (e.g. Unicode) is treated as binary. With the .gitattributes file you can define how Git interpretes the file. Setting the diff attribute manually lets Git interprete the file content as text and will do an usual diff.
Just add a .gitattributes to your repository root folder and set the diff attribute to the paths or files. Here's an example:
src/Acme/DemoBundle/Resources/public/js/i18n/* diff
doc/Help/NothingToSay.yml diff
*.css diff
If you want to check if there are attributes set on a file, you can do that with the help of git check-attr
git check-attr --all -- src/my_file.txt
Another nice reference about Git attributes could be found here.
Tested and verified code:
$( document ).ready(function() {
$('#messageForm').submit(function(e){
e.preventDefault();
});
$('#send').click(function(e){
$("#messageForm")[0].reset();
});
});
Javascript must be included in $(document).ready
and it must be with your logic.
Had similar problem. To resolve it, updated from svn trunk with option of priority of local files.
svn update path/ --accept=mine-full
After You could commit as usual. Of course, be careful using it.
A quick google pointed me to this page. It explains that from sql server 2005 onwards you can set the default schema of a user with the ALTER USER statement. Unfortunately, that means that you change it permanently, so if you need to switch between schemas, you would need to set it every time you execute a stored procedure or a batch of statements. Alternatively, you could use the technique described here.
If you are using sql server 2000 or older this page explains that users and schemas are then equivalent. If you don't prepend your table name with a schema\user, sql server will first look at the tables owned by the current user and then the ones owned by the dbo to resolve the table name. It seems that for all other tables you must prepend the schema\user.
In Python, paths are relative to the current working directory, which in most cases is the directory from which you run your program. The current working directory is very likely not as same as the directory of your module file, so using a path relative to your current module file is always a bad choice.
Using absolute path should be the best solution:
import os
package_dir = os.path.dirname(os.path.abspath(__file__))
thefile = os.path.join(package_dir,'test.cvs')

You can use Query.values, Query.values
session.query(SomeModel).values('id', 'user')
The best thing is to actually use the kernel makefile to install the module:
Here is are snippets to add to your Makefile
around the top add:
PWD=$(shell pwd)
VER=$(shell uname -r)
KERNEL_BUILD=/lib/modules/$(VER)/build
# Later if you want to package the module binary you can provide an INSTALL_ROOT
# INSTALL_ROOT=/tmp/install-root
around the end add:
install:
$(MAKE) -C $(KERNEL_BUILD) M=$(PWD) \
INSTALL_MOD_PATH=$(INSTALL_ROOT) modules_install
and then you can issue
sudo make install
this will put it either in /lib/modules/$(uname -r)/extra/
or /lib/modules/$(uname -r)/misc/
and run depmod appropriately
To disable the complete select2 box, that is no deletion of already selected values and no new insertion, use:
$("id-select2").prop("disabled", true);
where id-select2
is the unique id of select2. you can also use any particular class if defined to address the dropdown.
$("#closeLink").click(closeIt);
Let's say you want to call your function passing some args to it i.e., closeIt(1, false)
. Then, you should build an anonymous function and call closeIt
from it.
$("#closeLink").click(function() {
closeIt(1, false);
});
You should learn about the Media queries for CSS. The site you referring to is using the same. The site is basically using the different CSS everytime the browser window size is changining. Here's the link for samples

Methods within an anonomyous inner class may be invoked well after the thread that spawned it has terminated. In your example, the inner class will be invoked on the event dispatch thread and not in the same thread as that which created it. Hence, the scope of the variables will be different. So to protect such variable assignment scope issues you must declare them final.

Three things to know:
%1

%%f
Why's that?
For example, if we execute your (simplified) command line
FOR /f %f in ('dir /b .') DO somecommand %f
in a batch file, rule 2 would try to interpret
%f in ('dir /b .') DO somecommand %
as a variable. In order to prevent that, you have to apply rule 3 and escape the %
with an second %
:
FOR /f %%f in ('dir /b .') DO somecommand %%f

It is correctly mentioned in the error: you cannot make a static reference to non-static type T. The reason is the type parameter T
can be replaced by any of the type argument e.g. Clazz<String>
or Clazz<integer>
etc. But static fields/methods are shared by all non-static objects of the class.
The following excerpt is taken from the doc:
A class's static field is a class-level variable shared by all non-static objects of the class. Hence, static fields of type parameters are not allowed. Consider the following class:
public class MobileDevice<T> { private static T os; // ... }
If static fields of type parameters were allowed, then the following code would be confused:
MobileDevice<Smartphone> phone = new MobileDevice<>(); MobileDevice<Pager> pager = new MobileDevice<>(); MobileDevice<TabletPC> pc = new MobileDevice<>();
Because the static field os is shared by phone, pager, and pc, what is the actual type of os? It cannot be Smartphone, Pager, and TabletPC at the same time. You cannot, therefore, create static fields of type parameters.
As rightly pointed out by chris in his answer you need to use type parameter with the method and not with the class in this case. You can write it like:
static <E> void doIt(E object)

The bundle identifier is an ID for your application used by the system as a domain for which it can store settings and reference your application uniquely.
It is represented in reverse DNS notation and it is recommended that you use your company name and application name to create it.
An example bundle ID for an App called The Best App by a company called Awesome Apps would look like:
com.awesomeapps.thebestapp
In this case the suffix is thebestapp
.
You can either go the LoadLibrary/GetProcAddress route (as Harper mentioned in his answer, here's link to the run-time dynamic linking MSDN sample again) or you can link your console application to the .lib produced from the DLL project and include the hea.h file with the declaration of your function (as described in the load-time dynamic linking MSDN sample)
In both cases, you need to make sure your DLL exports the function you want to call properly. The easiest way to do it is by using __declspec(dllexport) on the function declaration (as shown in the creating a simple dynamic-link library MSDN sample), though you can do it also through the corresponding .def file in your DLL project.
For more information on the topic of DLLs, you should browse through the MSDN About Dynamic-Link Libraries topic.

You can try with textContent.
var productId = val[key].textContent;
It sounds like you are doing this on the main UI thread in the app. The UI thread is responsible for pumping windows messages as the arrive, and yet because yours is blocked in database calls it is unable to do so. This can cause problems with system wide messages.
