PriorityQueue<Integer> lowers = new PriorityQueue<>((o1, o2) -> -1 * o1.compareTo(o2));
from Queue API:
The offer method inserts an element if possible, otherwise returning false. This differs from the Collection.add method, which can fail to add an element only by throwing an unchecked exception. The offer method is designed for use when failure is a normal, rather than exceptional occurrence, for example, in fixed-capacity (or "bounded") queues.
Use std::greater
as the comparison function:
std::priority_queue<int, std::vector<int>, std::greater<int> > my_min_heap;
You have to define the compare first. There are 3 ways to do that:
It's easy to use class/struct because easy to declare just write this line of code above your executing code
struct compare{
public:
bool operator()(Node& a,Node& b) // overloading both operators
{
return a.w < b.w: // if you want increasing order;(i.e increasing for minPQ)
return a.w > b.w // if you want reverse of default order;(i.e decreasing for minPQ)
}
};
Calling code:
priority_queue<Node,vector<Node>,compare> pq;

I see that you are all editing or updating from our files
For those who want automatic updates you can use our Ubuntu PPA
sudo add-apt-repository ppa:phpmyadmin/ppa
And for Debian users you will need to wait for next version of Debian or use PPA
Ubuntu 20 has phpMyAdmin 4.9 or a later version
Countable issues on our tracker
TLDR Update to latest 4.9 or 5.0 version to solve this issue.
If you have a SOCK_STREAM
socket, recv
just gets "up to the first 3000 bytes" from the stream. There is no clear guidance on how big to make the buffer: the only time you know how big a stream is, is when it's all done;-).
If you have a SOCK_DGRAM
socket, and the datagram is larger than the buffer, recv
fills the buffer with the first part of the datagram, returns -1, and sets errno to EMSGSIZE. Unfortunately, if the protocol is UDP, this means the rest of the datagram is lost -- part of why UDP is called an unreliable protocol (I know that there are reliable datagram protocols but they aren't very popular -- I couldn't name one in the TCP/IP family, despite knowing the latter pretty well;-).
To grow a buffer dynamically, allocate it initially with malloc
and use realloc
as needed. But that won't help you with recv
from a UDP source, alas.
The default parser can parse your input. So you don't need a custom formatter and
String dateTime = "2012-02-22T02:06:58.147Z";
ZonedDateTime d = ZonedDateTime.parse(dateTime);
works as expected.
marker = new google.maps.Marker({
map:map,
// draggable:true,
// animation: google.maps.Animation.DROP,
position: new google.maps.LatLng(59.32522, 18.07002),
icon: 'http://cdn.com/my-custom-icon.png' // null = default icon
});
You can derive a normal array from the ArrayBuffer
by using Array.prototype.slice
.
Use a function like Array.prototype.map
to convert bytes in to characters and join
them together to forma string.
function arrayBufferToBase64(ab){
var dView = new Uint8Array(ab); //Get a byte view
var arr = Array.prototype.slice.call(dView); //Create a normal array
var arr1 = arr.map(function(item){
return String.fromCharCode(item); //Convert
});
return window.btoa(arr1.join('')); //Form a string
}
This method is faster since there are no string concatenations running in it.

Simply difference between Forward

(String url) is
forward():
forward()
method is executed in the server side.forward ()
method is provided by the servlet container.sendRedirect()
method.RequestDispatcher
interface.sendRedirect():
sendRedirect()
method is executed in the client side.sendRedirect()
method is provided under HTTP
so it can be used only with HTTP
clients.sendRedirect()
method is slower because when new request is created old request object is lost.HttpServletResponse
.That's not possible. localhost
always defaults to the loopback device on the local operating system.
As your virtual machine runs its own operating system it has its own loopback device which you cannot access from the outside.
If you want to access it e.g. in a browser, connect to it using the local IP instead:
http://192.168.180.1:8000
This is just an example of course, you can find out the actual IP by issuing an ifconfig
command on a shell in the guest operating system.
Disable the button on the OnClick event, then re-enable on the AJAX callback event handler. Here is how I do it with jQuery.
<script>
$(document).ready(function() {
$('#buttonId').click(function() {
$(this).attr('disabled', 'disabled');
callAjax();
});
});
function callAjax()
{
$.ajax({
url: 'ajax/test.html',
success: function(data) {
//enable button
$('#buttonId').removeAttr('disabled');
}
});
}
</script>
Use $evalAsync if you want your callback (i.e., test()) to be executed after the DOM is constructed, but before the browser renders. This will prevent flicker -- ref.
if (scope.$last) {
scope.$evalAsync(attr.onFinishRender);
}
If you really want to call your callback after rendering, use $timeout:
if (scope.$last) {
$timeout(function() {
scope.$eval(attr.onFinishRender);
});
}
I prefer $eval instead of an event. With an event, we need to know the name of the event and add code to our controller for that event. With $eval, there is less coupling between the controller and the directive.
Another simple option that updates on a click of the checkbox.
HTML:
<input type="checkbox" id="checkbox/>
<input disabled type="submit" id="item"/>
jQuery:
$('#checkbox').click(function() {
if (this.checked) {
$('#item').prop('disabled', false); // If checked enable item
} else {
$('#item').prop('disabled', true); // If checked disable item
}
});

libsysfs does look potentially useful, but not directly from a shell script. There's a program that comes with it called systool which will do what you want, though it may be easier to just look in /sys directly rather than using another program to do it for you.

Useful to populate dynamic actions list, and listen to selected action:
var categories = ["Science", "History", "Industry", "Agriculture"]
var handlerSelectedCategory: ((Int) -> ())?
func prepareActions(for title: String, index: Int) -> UIAlertAction {
let alertAction = UIAlertAction(title: title, style: .default) { (action) in
self.handlerSelectedCategory?(index)
}
return alertAction
}
@objc func presentActions() {
let optionMenu = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
// add dymamic options
for (index, element) in self.categories.enumerated() {
optionMenu.addAction(prepareActions(for: element, index: index))
}
// cancel
let cancelAction = UIAlertAction(title: "Cancel", style: .destructive)
optionMenu.addAction(cancelAction)
handlerSelectedCategory = { index in
print(index, self.categories[index])
}
self.present(optionMenu, animated: true, completion: nil)
}
by splitting with newlines.
for line in wallop_of_a_string_with_many_lines.split('\n'):
#do_something..
if you iterate over a string, you are iterating char by char in that string, not by line.
>>>string = 'abc'
>>>for line in string:
print line
a
b
c
You can also use -match against a Regular expression. Ex:
if ($dbUserName -match ".{8}" )
{
Write-Output " Please enter more than 8 characters "
$dbUserName=read-host " Re-enter database user name"
}
Also if you're like me and like your curly braces to be in the same horizontal position for your code blocks, you can put that on a new line, since it's expecting a code block it will look on next line. In some commands where the first curly brace has to be in-line with your command, you can use a grave accent marker (`) to tell powershell to treat the next line as a continuation.
Works fine too:
/* small screen portrait */
@media (max-width: 321px) {
.pull-right {
float: none!important;
}
}
/* small screen lanscape */
@media (max-width: 480px) {
.pull-right {
float: none!important;
}
}
In my system its the \ key. it's used for commands so that you can combine it with other chars.

You're correct, length

From the Arrays tutorial:
The length of an array is established when the array is created. After creation, its length is fixed.

Here's a trick I recently worked out for executing raw sql with binds:
binds = SomeRecord.bind(a_string_field: value1, a_date_field: value2) +
SomeOtherRecord.bind(a_numeric_field: value3)
SomeRecord.connection.exec_query <<~SQL, nil, binds
SELECT *
FROM some_records
JOIN some_other_records ON some_other_records.record_id = some_records.id
WHERE some_records.a_string_field = $1
AND some_records.a_date_field < $2
AND some_other_records.a_numeric_field > $3
SQL
where ApplicationRecord
defines this:
# Convenient way of building custom sql binds
def self.bind(column_values)
column_values.map do |column_name, value|
[column_for_attribute(column_name), value]
end
end
and that is similar to how AR binds its own queries.
In Xcode 7 a quick way is to use Product > Archive. It's probably not a signed copy for submission but it's good enough to give to somebody else for testing.
Using generics (as in the above answers) is your best bet here. I've just double checked and:
test.put("test", arraylistone);
ArrayList current = new ArrayList();
current = (ArrayList) test.get("test");
will work as well, through I wouldn't recommend it as the generics ensure that only the correct data is added, rather than trying to do the handling at retrieval time.
("#tblEntAttributes tbody")
needs to be
$("#tblEntAttributes tbody")
.
You are not selecting the element with the correct syntax
Here's an example of both
$(newRowContent).appendTo($("#tblEntAttributes"));
and
$("#tblEntAttributes tbody").append(newRowContent);

Assuming B is the current branch:
$ git diff A <file-path> > patch.tmp
$ git apply patch.tmp -R
Note that this only applies changes to the local file. You'll need to commit afterwards.
What Dragan B suggested is right way to go for Bootstrap 4. I have put one example below. e.g. mr-3 is margin-right:1rem!important
<div class="btn-toolbar pull-right">
<button type="button" class="btn mr-3">btn1</button>
<button type="button" class="btn mr-3">btn2</button>
<button type="button" class="btn">btn3</button>
</div>
p.s: in my case I wanted my buttons to be displayed to the right of the screen and hence pull-right.
select field1, field2, '' as newfield from table1
This Will Do you Job
I think the canonical method is:
while IFS=, read field1 field2 field3 field4 field5 field6; do
do stuff
done < CSV.file
If you don't know or don't care about how many fields there are:
IFS=,
while read line; do
# split into an array
field=( $line )
for word in "${field[@]}"; do echo "$word"; done
# or use the positional parameters
set -- $line
for word in "$@"; do echo "$word"; done
done < CSV.file

Better way is just to add "save action" so when you save the project it will clear the unused import's and format the code as well if you like .

I think you can use the nrows
parameter. From the docs:
nrows : int, default None
Number of rows of file to read. Useful for reading pieces of large files
which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):
In [1]: import pandas as pd
In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)

I believe the error code indicates that the response was empty, (as not even headers were returned). This means the connection was accepted and then closed gracefully (TCP FIN). There are a number of things which could cause this, but based off of your description, some form of firewall seems the most likely culprit.
You may try like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
g.drawRect (x, y, width, height); //can use either of the two//
g.fillRect (x, y, width, height);
g.setColor(color);
}
}
where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue
if you want to use rectangle object you could do it like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
g.setColor(color);
}
}
A simple method will be like this:
Match match1 = Regex.Match(<input_string>, @"(?=.{7})");
match1.Success ensures that there are at least 8 characters.
Match match2 = Regex.Match(<input_string>, [^a-zA-Z]);
match2.Success ensures that there is at least one special character or number within the string.
So, match1.Success && match2.Success guarantees will get what you want.
OpenURI is the best; it's as simple as
require 'open-uri'
response = open('http://example.com').read
To get the value of the selected Radio Button, Use RadioButtonName and the Form Id containing the RadioButton.
$('input[name=radioName]:checked', '#myForm').val()

In other words, yes, the iterators are being invalidated, but you're getting lucky in your example (or really unlucky, as you're not seeing the negative effects of undefined behavior). One solution to this is to create a temporary iterator, increment the temp, delete the target iterator, then set the target to the temp. For example, re-write your loop as follows:
std::set<int>::iterator it = numbers.begin();
std::set<int>::iterator tmp;
// iterate through the set and erase all even numbers
for ( ; it != numbers.end(); )
{
int n = *it;
if (n % 2 == 0)
{
tmp = it;
++tmp;
numbers.erase(it);
it = tmp;
}
else
{
++it;
}
}
Simply call list
on the generator.
lst = list(gen)
lst
Be aware that this affects the generator which will not return any further items.
You also cannot directly call list
in IPython, as it conflicts with a command for listing lines of code.
Tested on this file:
def gen():
yield 1
yield 2
yield 3
yield 4
yield 5
import ipdb
ipdb.set_trace()
g1 = gen()
text = "aha" + "bebe"
mylst = range(10, 20)
which when run:
$ python code.py
> /home/javl/sandbox/so/debug/code.py(10)<module>()
9
---> 10 g1 = gen()
11
ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
11
---> 12 text = "aha" + "bebe"
13
ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.
There are debugger commands p
and pp
that will print
and prettyprint
any expression following them.
So you could use it as follows:
$ python code.py
> /home/javl/sandbox/so/debug/code.py(10)<module>()
9
---> 10 g1 = gen()
11
ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
11
---> 12 text = "aha" + "bebe"
13
ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c
There is also an exec
command, called by prefixing your expression with !
, which forces debugger to take your expression as Python one.
ipdb> !list(g1)
[]
For more details see help p
, help pp
and help exec
when in debugger.
ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']
You can try this too:
public class Match
{
[Key]
public int MatchId { get; set; }
[ForeignKey("HomeTeam"), Column(Order = 0)]
public int? HomeTeamId { get; set; }
[ForeignKey("GuestTeam"), Column(Order = 1)]
public int? GuestTeamId { get; set; }
public float HomePoints { get; set; }
public float GuestPoints { get; set; }
public DateTime Date { get; set; }
public virtual Team HomeTeam { get; set; }
public virtual Team GuestTeam { get; set; }
}
When you make a FK column allow NULLS, you are breaking the cycle. Or we are just cheating the EF schema generator.
In my case, this simple modification solve the problem.
I found a post suggesting a solution for that. It's about to run:
svn resolve --accept working <YourPath>
which will claim the local version files as OK.
You can run it for single file or entire project catalogues.
Try this:
<li onclick="getPaging(this.id)" id="1">1</li>
<li onclick="getPaging(this.id)" id="2">2</li>
function getPaging(str)
{
$("#loading-content").load("dataSearch.php?"+str, hideLoader);
}
you can also import the FunctionType from types and test it with the class.__dict__
:
from types import FunctionType
class Foo:
def bar(self): pass
def baz(self): pass
def methods(cls):
return [x for x, y in cls.__dict__.items() if type(y) == FunctionType]
methods(Foo) # ['bar', 'baz']
model.update({"_id": 1, "items.id": "2"},
{$set: {"items.$.name": "yourValue","items.$.value": "yourvalue"}})
LabelEncoding worked for me (basically you've to encode your data feature-wise) (mydata is a 2d array of string datatype):
myData=np.genfromtxt(filecsv, delimiter=",", dtype ="|a20" ,skip_header=1);
from sklearn import preprocessing
le = preprocessing.LabelEncoder()
for i in range(*NUMBER OF FEATURES*):
myData[:,i] = le.fit_transform(myData[:,i])
var exec = require('child_process').exec;
exec('pwd', function callback(error, stdout, stderr){
// result
});
If anyone else is having a nullptr on the searchview variable, I found out that the item setup is a tiny bit different:
old:
android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView"
new:
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="androidx.appcompat.widget.SearchView"
pre-android x:
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"
For more information, it's updated documentation is located here.
You need to specify an offset to addr2line, not a virtual address (VA). Presumably if you had address space randomization turned off, you could use a full VA, but in most modern OSes, address spaces are randomized for a new process.
Given the VA 0x4005BDC
by valgrind, find the base address of your process or library in memory. Do this by examining the /proc/<PID>/maps
file while your program is running. The line of interest is the text
segment of your process, which is identifiable by the permissions r-xp
and the name of your program or library.
Let's say that the base VA is 0x0x4005000
. Then you would find the difference between the valgrind supplied VA and the base VA: 0xbdc
. Then, supply that to add2line:
addr2line -e a.out -j .text 0xbdc
And see if that gets you your line number.
Expanding on Timothy's answer...
If you're a web developer looking to use wkhtmltopdf as part of your web app, you can simply install it into your /usr/bin/
folder like so:
cd /usr/bin/
curl -C - -O http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
tar -xvjf wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
mv wkhtmltopdf-i386 wkhtmltopdf
You can now run it anywhere using wkhtmltopdf
.
I personally use the Snappy library in PHP. Here is an example of how easy it is to create a PDF:
<?php
// Create new PDF
$pdf = new \Knp\Snappy\Pdf('wkhtmltopdf');
// Set output header
header('Content-Type: application/pdf');
// Generate PDF from HTML
echo $pdf->getOutputFromHtml('<h1>Title</h1><p>Your content goes here.</p>');
The other answers show what's wrong with your code. But there's also a built-in way to do this, if you weren't just doing this for an exercise:
>>> 'banana'.count('a')
3
Danben gave this corrected version:
def count_letters(word, char):
count = 0
for c in word:
if char == c:
count += 1
return count
Here are some other ways to do it, hopefully they will teach you more about Python!
Similar, but shorter for
loop. Exploits the fact that booleans can turn into 1 if true and 0 if false:
def count_letters(word, char):
count = 0
for c in word:
count += (char == c)
return count
Short for loops can generally be turned into list/generator comprehensions. This creates a list of integers corresponding to each letter, with 0 if the letter doesn't match char
and 1 if it does, and then sums them:
def count_letters(word, char):
return sum(char == c for c in word)
The next one filters out all the characters that don't match char
, and counts how many are left:
def count_letters(word, char):
return len([c for c in word if c == char])
You can use the before
or after
pseudo-element and apply some CSS to it. There are various ways. You can add both before
and after
, and rotate and position each of them to form one of the bars. An easier solution is adding two borders to just the before
element and rotate it using transform: rotate
.
Scroll down for a different solution that uses an actual element instead of the pseuso elements
In this case, I've added the arrows as bullets in a list and used em
sizes to make them size properly with the font of the list.

Of course you don't need to use before
or after
, you can apply the same trick to a normal element as well. For the list above it is convenient, because you don't need additional markup. But sometimes you may want (or need) the markup anyway. You can use a div
or span
for that, and I've even seen people even recycle the i
element for 'icons'. So that markup could look like below. Whether using <i>
for this is right is debatable, but you can use span for this as well to be on the safe side.
/* Default icon formatting */_x000D_
i {_x000D_
display: inline-block;_x000D_
font-style: normal;_x000D_
position: relative;_x000D_
}_x000D_
_x000D_
/* Additional formatting for arrow icon */_x000D_
i.arrow {_x000D_
/* top: 2pt; Uncomment this to lower the icons as requested in comments*/_x000D_
width: 0.4em;_x000D_
height: 0.4em;_x000D_
border-right: 0.2em solid black;_x000D_
border-top: 0.2em solid black;_x000D_
transform: rotate(45deg);_x000D_
}
_x000D_
And so you can have an <i class="arrow" title="arrow icon"></i> in your text._x000D_
This arrow is <i class="arrow" title="arrow icon"></i> used to be deliberately lowered slightly on request._x000D_
I removed that for the general public <i class="arrow" title="arrow icon"></i> but you can uncomment the line with 'top' <i class="arrow" title="arrow icon"></i> to restore that effect.

ActionResult is an abstract class that can have several subtypes.
ViewResult - Renders a specifed view to the response stream
PartialViewResult - Renders a specifed partial view to the response stream
EmptyResult - An empty response is returned
RedirectResult - Performs an HTTP redirection to a specifed URL
RedirectToRouteResult - Performs an HTTP redirection to a URL that is determined by the routing engine, based on given route data
JsonResult - Serializes a given ViewData object to JSON format
JavaScriptResult - Returns a piece of JavaScript code that can be executed on the client
ContentResult - Writes content to the response stream without requiring a view
FileContentResult - Returns a file to the client
FileStreamResult - Returns a file to the client, which is provided by a Stream
FilePathResult - Returns a file to the client
If you are reading from that file using FileStream and then wanting to delete it, make sure you close the FileStream before you call the File.Delete(path). I had this issue.
var filestream = new System.IO.FileStream(@"C:\Test\PutInv.txt", System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite);
filestream.Close();
File.Delete(@"C:\Test\PutInv.txt");
I think the cleanest way is definitely to go the AOP route. Make a few aspects, add the necessary attributes, and you never have to check thread affinity again.
So another way, which I prefer, is to just split the values, for example:
#/path/to/config.cfg
[Numbers]
first_row = 1,2,4,8,12,24,36,48
Could be loaded like this into a list of strings or integers, as follows:
import configparser
config = configparser.ConfigParser()
config.read('/path/to/config.cfg')
# Load into a list of strings
first_row_strings = config.get('Numbers', 'first_row').split(',')
# Load into a list of integers
first_row_integers = [int(x) for x in config.get('Numbers', 'first_row').split(',')]
This method prevents you from needing to wrap your values in brackets to load as JSON.
To explain in common usecase/purpose or layman way:
TrustStore : As the name indicates, its normally used to store the certificates of trusted entities. A process can maintain a store of certificates of all its trusted parties which it trusts.
keyStore : Used to store the server keys (both public and private) along with signed cert.
During the SSL handshake,
A client tries to access https://
And thus, Server responds by providing a SSL certificate (which is stored in its keyStore)
Now, the client receives the SSL certificate and verifies it via trustStore (i.e the client's trustStore already has pre-defined set of certificates which it trusts.). Its like : Can I trust this server ? Is this the same server whom I am trying to talk to ? No middle man attacks ?
Once, the client verifies that it is talking to server which it trusts, then SSL communication can happen over a shared secret key.
Note : I am not talking here anything about client authentication on server side. If a server wants to do a client authentication too, then the server also maintains a trustStore to verify client. Then it becomes mutual TLS
Another way is use a program listening in one port that analyses the kind of traffic (ssh, https, etc) it redirects internally to another port on which the "real" service is listening.
For example, for Linux, sslh: https://github.com/yrutschle/sslh
It's compiling because printf
isn't type safe, since it uses variable arguments in the C sense1. printf
has no option for std::string
, only a C-style string. Using something else in place of what it expects definitely won't give you the results you want. It's actually undefined behaviour, so anything at all could happen.
The easiest way to fix this, since you're using C++, is printing it normally with std::cout
, since std::string
supports that through operator overloading:
std::cout << "Follow this command: " << myString;
If, for some reason, you need to extract the C-style string, you can use the c_str()
method of std::string
to get a const char *
that is null-terminated. Using your example:
#include <iostream>
#include <string>
#include <stdio.h>
int main()
{
using namespace std;
string myString = "Press ENTER to quit program!";
cout << "Come up and C++ me some time." << endl;
printf("Follow this command: %s", myString.c_str()); //note the use of c_str
cin.get();
return 0;
}
If you want a function that is like printf
, but type safe, look into variadic templates (C++11, supported on all major compilers as of MSVC12). You can find an example of one here. There's nothing I know of implemented like that in the standard library, but there might be in Boost, specifically boost::format
.
[1]: This means that you can pass any number of arguments, but the function relies on you to tell it the number and types of those arguments. In the case of printf
, that means a string with encoded type information like %d
meaning int
. If you lie about the type or number, the function has no standard way of knowing, although some compilers have the ability to check and give warnings when you lie.
You found the shorthand to set privileges for all existing tables in the given schema. The manual clarifies:
(but note that
ALL TABLES
is considered to include views and foreign tables).
Bold emphasis mine. serial
columns are implemented with nextval()
on a sequence as column default and, quoting the manual:
For sequences, this privilege allows the use of the
currval
andnextval
functions.
So if there are serial
columns, you'll also want to grant USAGE
(or ALL PRIVILEGES
) on sequences
GRANT USAGE ON ALL SEQUENCES IN SCHEMA foo TO mygrp;
Note: identity columns in Postgres 10 or later use implicit sequences that don't require additional privileges. (Consider upgrading serial
columns.)
You'll also be interested in DEFAULT PRIVILEGES
for users or schemas:
ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT ALL PRIVILEGES ON TABLES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo GRANT USAGE ON SEQUENCES TO staff;
ALTER DEFAULT PRIVILEGES IN SCHEMA foo REVOKE ...;
This sets privileges for objects created in the future automatically - but not for pre-existing objects.
Default privileges are only applied to objects created by the targeted user (FOR ROLE my_creating_role
). If that clause is omitted, it defaults to the current user executing ALTER DEFAULT PRIVILEGES
. To be explicit:
ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo GRANT ...;
ALTER DEFAULT PRIVILEGES FOR ROLE my_creating_role IN SCHEMA foo REVOKE ...;
Note also that all versions of pgAdmin III have a subtle bug and display default privileges in the SQL pane, even if they do not apply to the current role. Be sure to adjust the FOR ROLE
clause manually when copying the SQL script.
I think that this is the correct way:
class Game extends Eloquent {
// many more stuff here
// relation without any constraints ...works fine
public function videos() {
return $this->hasMany('Video');
}
// results in a "problem", se examples below
public function available_videos() {
return $this->videos()->where('available','=', 1);
}
}
And then you'll have to
$game = Game::find(1);
var_dump( $game->available_videos()->get() );
When the game starts:
long tStart = System.currentTimeMillis();
When the game ends:
long tEnd = System.currentTimeMillis();
long tDelta = tEnd - tStart;
double elapsedSeconds = tDelta / 1000.0;
Well, I'm a bit late but still would like to share my way of schema creation.
I have schemas for everything that can be described by a word, like you would do it in the classical OOP.
E.G.
Every schema can be saved as a Document or Subdocument, so I declare this for each schema.
Document:
Subdocument:
The answer of this question is lies in the internal working of java compiler(constructor chaining). If we see the internal working of java compiler:
public class Bank {
public void printBankBalance(){
System.out.println("10k");
}
}
class SBI extends Bank{
public void printBankBalance(){
System.out.println("20k");
}
}
After compiling this look like:
public class Bank {
public Bank(){
super();
}
public void printBankBalance(){
System.out.println("10k");
}
}
class SBI extends Bank {
SBI(){
super();
}
public void printBankBalance(){
System.out.println("20k");
}
}
when we extends class and create an object of it, one constructor chain will run till Object
class.
Above code will run fine. but if we have another class called Car
which extends Bank
and one hybrid(multiple inheritance) class called SBICar
:
class Car extends Bank {
Car() {
super();
}
public void run(){
System.out.println("99Km/h");
}
}
class SBICar extends Bank, Car {
SBICar() {
super(); //NOTE: compile time ambiguity.
}
public void run() {
System.out.println("99Km/h");
}
public void printBankBalance(){
System.out.println("20k");
}
}
In this case(SBICar) will fail to create constructor chain(compile time ambiguity).
For interfaces this is allowed because we cannot create an object of it.
For new concept of default
and static
method kindly refer default in interface.
Hope this will solve your query. Thanks.

Sorry, this is a lousy answer. Apparently this has been an issue for almost two years so don't hold your breath.
Here is the official request that you can "star"
Probably the closest you can come is rolling your own service with Google App Engine/Python and exposing whatever subset you need with your own JS library. Though I'd love to have a better solution myself.
Async:
fs.readFile('test.txt', 'utf8', callback);
Sync:
var content = fs.readFileSync('test.txt', 'utf8');
It seams you need to versionate, so when some change happens browser will catch something new and user won't need to clear browser's cache.
You can do it by subfolders (example /css/v1/style.css)
or by filename (example: css/style_v1.css)
or even by setting different folders for your website, example:
www.mywebsite.com/site1
www.mywebsite.com/site2
www.mywebsite.com/site3
And use a .htaccess or even change httpd.conf to redirect to your current application.
If's about one image or page:
<?$time = date("H:i:s");?>
<img src="myfile.jpg?time=<?$time;?>">
You can use $time on parts when you don't wanna cache. So it will always pull a new image. Versionate it seams a better approach, otherwise it can overload your server. Remember, browser's cache it's not only good to user experience, but also for your server.

This happens because you trying to run service at the same port and there is an already running application.
This can happen because your service is not stopped in the process stack. Then you just have to kill this process.
There is no need to install anything here is the one line command to kill all running python processes.

Now, it's very much simplified in Visual Studio 2015 and later. You can do downgrade / upgrade within the User interface itself, without executing commands in the Package Manager Console.
Right click on your project and *go to Manage NuGet Packages.
Look at the below image.
Select your Package and Choose the Version
, which you wanted to install.Very very simple, isn't it? :)
Project build settings have a block 'Swift Compiler - Languages', which stores information about Swift Language Version in key-value format. It will show you all available (supported) Swift Language Version for your Xcode and active version also by a tick mark.
Project ? (Select Your Project Target) ? Build Settings ? (Type 'swift_version' in the Search bar) Swift Compiler Language ? Swift Language Version ? Click on Language list to open it (and there will be a tick mark on any one of list-item, that will be current swift version).
Look at this snapshot, for easy understanding:
With help of following code, programmatically you can find Swift version supported by your project.
#if swift(>=5.3)

Here is result using Playground (with Xcode 11.x)
The onload event does not always work on IE7/8 in <head> ... </head>
You can force it by adding an onload script at the end of your page before the tag as below.
<script>
window.onload();
</script>
</body>
You can also create your own (if unhappy with the options available).
Creating your own Timer
implementation is pretty basic stuff.
This is an example for an application that needed COM object access on the same thread as the rest of my codebase.
/// <summary>
/// Internal timer for window.setTimeout() and window.setInterval().
/// This is to ensure that async calls always run on the same thread.
/// </summary>
public class Timer : IDisposable {
public void Tick()
{
if (Enabled && Environment.TickCount >= nextTick)
{
Callback.Invoke(this, null);
nextTick = Environment.TickCount + Interval;
}
}
private int nextTick = 0;
public void Start()
{
this.Enabled = true;
Interval = interval;
}
public void Stop()
{
this.Enabled = false;
}
public event EventHandler Callback;
public bool Enabled = false;
private int interval = 1000;
public int Interval
{
get { return interval; }
set { interval = value; nextTick = Environment.TickCount + interval; }
}
public void Dispose()
{
this.Callback = null;
this.Stop();
}
}
You can add events as follows:
Timer timer = new Timer();
timer.Callback += delegate
{
if (once) { timer.Enabled = false; }
Callback.execute(callbackId, args);
};
timer.Enabled = true;
timer.Interval = ms;
timer.Start();
Window.timers.Add(Environment.TickCount, timer);
To make sure the timer works you need to create an endless loop as follows:
while (true) {
// Create a new list in case a new timer
// is added/removed during a callback.
foreach (Timer timer in new List<Timer>(timers.Values))
{
timer.Tick();
}
}
What you've done by following those directions is created an entirely new Python installation, separate from the system Python that is managed by Ubuntu packages.
Modules you had installed in the system Python (e.g. installed via packages, or by manual installation using the system Python to run the setup process) will not be available, since your /usr/local
-based python
is configured to look in its own module directories, not the system Python's.
You can re-add missing modules now by building them and installing them using your new /usr/local
-based Python.
You forgot the C: after the file:///
This works for me

For those of you who would like to simulate the set_contents_from_string
like boto2 methods, you can try
import boto3
from cStringIO import StringIO
s3c = boto3.client('s3')
contents = 'My string to save to S3 object'
target_bucket = 'hello-world.by.vor'
target_file = 'data/hello.txt'
fake_handle = StringIO(contents)
# notice if you do fake_handle.read() it reads like a file handle
s3c.put_object(Bucket=target_bucket, Key=target_file, Body=fake_handle.read())
For Python3:
In python3 both StringIO and cStringIO are gone. Use the StringIO
import like:
from io import StringIO
To support both version:
try:
from StringIO import StringIO
except ImportError:
from io import StringIO
I don't believe there's anything built-in for this. It's made tricky by the fact that it's rare for a single line to change several times without the rest of the file changing substantially too, so you'll tend to end up with the line numbers changing a lot.
If you're lucky enough that the line always has some identifying characteristic, e.g. an assignment to a variable whose name never changed, you could use the regex choice for git blame -L
. For example:
git blame -L '/variable_name *= */',+1
But this only finds the first match for that regex, so if you don't have a good way of matching the line, it's not too helpful.
You could hack something up, I suppose. I don't have time to write out code just now, but... something along these lines. Run git blame -n -L $n,$n $file
. The first field is the previous commit touched, and the second field is the line number in that commit, since it could've changed. Grab those, and run git blame -n $n,$n $commit^ $file
, i.e. the same thing starting from the commit before the last time the file was changed.
(Note that this will fail you if the last commit that changed the line was a merge commit. The primary way this could happen if the line was changed as part of a merge conflict resolution.)
Edit: I happened across this mailing list post from March 2011 today, which mentions that tig
and git gui
have a feature that will help you do this. It looks like the feature has been considered, but not finished, for git itself.
I have seen significant performance gains from using the EnsureCapacity(int capacity)
method call on an instance of StringBuilder
before using it for any string storage. I usually call that on the line of code after instantiation. It has the same effect as if you instantiate the StringBuilder
like this:
var sb = new StringBuilder(int capacity);
This call allocates needed memory ahead of time, which causes fewer memory allocations during multiple Append()
operations. You have to make an educated guess on how much memory you will need, but for most applications this should not be too difficult. I usually err on the side of a little too much memory (we are talking 1k or so).
If you need to store the keys separately, here's a solution that requires less typing than every other solution presented thus far, using Extended Iterable Unpacking (python3.x+).
newdict = {1: 0, 2: 0, 3: 0}
*k, = newdict
k
# [1, 2, 3]
+---------------------------------------------------------+
¦ k = list(d) ¦ 9 characters (excluding whitespace) ¦
+---------------+-----------------------------------------¦
¦ k = [*d] ¦ 6 characters ¦
+---------------+-----------------------------------------¦
¦ *k, = d ¦ 5 characters ¦
+---------------------------------------------------------+
Option down
resolve this problem
I run my compose file:
docker-compose -f docker/docker-compose.yml up -d
then I delete all with down --rmi all
docker-compose -f docker/docker-compose.yml down --rmi all
Stops containers and removes containers, networks, volumes, and images
created by `up`.
By default, the only things removed are:
- Containers for services defined in the Compose file
- Networks defined in the `networks` section of the Compose file
- The default network, if one is used
Networks and volumes defined as `external` are never removed.
Usage: down [options]
Options:
--rmi type Remove images. Type must be one of:
'all': Remove all images used by any service.
'local': Remove only images that don't have a custom tag
set by the `image` field.
-v, --volumes Remove named volumes declared in the `volumes` section
of the Compose file and anonymous volumes
attached to containers.
--remove-orphans Remove containers for services not defined in the
Compose file
One more solution(sorry if duplicates) for all occurrences:
values = [1,2,3,1,2,4,5,6,3,2,1]
map(lambda val: (val, [i for i in xrange(len(values)) if values[i] == val]), values)
Form1 form = new Form1();
form.textBox1.Text = "test";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:strSomeTextWithLinks];
NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor redColor],
NSUnderlineColorAttributeName: [UIColor blueColor],
NSUnderlineStyleAttributeName: @(NSUnderlinePatternSolid)};
customTextView.linkTextAttributes = linkAttributes; // customizes the appearance of links
textView.attributedText = attributedString;
As the html5 way (my previous answer) is not available in all browsers, heres another slightly hack way.
This solution requires you are serving the intended file from same domain, OR has CORS permission.
application/octet-stream
.
Result should look likedata:application/octet-stream;base64,SGVsbG8sIFdvcmxkIQ%3D%3D
Now set location.href = data
. This will cause the browser to download the file. Unfortunately you can't set file name or extension this way. Fiddling with the media-type could yield something.
See details: https://developer.mozilla.org/en-US/docs/Web/HTTP/data_URIs
For a somewhat narrow use case, docker issue 8838 mentions this sort-of-hack:
You just stop docker daemon and change container config in /var/lib/docker/containers/[container-id]/config.json (sic)
This solution updates the environment variables without the need to delete and re-run the container, having to migrate volumes and remembering parameters to run
.
However, this requires a restart of the docker daemon. And, until issue issue 2658 is addressed, this includes a restart of all containers.
In javascript there are trues and truthys. When something is true it is obviously true or false. When something is truthy it may or may not be a boolean, but the "cast" value of is a boolean.
Examples.
true == true; // (true) true
1 == true; // (true) truthy
"hello" == true; // (true) truthy
[1, 2, 3] == true; // (true) truthy
[] == false; // (true) truthy
false == false; // (true) true
0 == false; // (true) truthy
"" == false; // (true) truthy
undefined == false; // (true) truthy
null == false; // (true) truthy
This can make things simpler if you want to check if a string is set or an array has any values.
var users = [];
if(users) {
// this array is populated. do something with the array
}
var name = "";
if(!name) {
// you forgot to enter your name!
}
And as stated. expect(something).toBe(true)
and expect(something).toBeTrue()
is the same. But expect(something).toBeTruthy()
is not the same as either of those.
Most likely you're looking for the ToCharArray() method. However, you will need to do slightly more work if a string[]
is required, as you noted in your post.
string str = "this is a test.";
char[] charArray = str.ToCharArray();
string[] strArray = str.Select(x => x.ToString()).ToArray();
Edit: If you're worried about the conciseness of the conversion, I suggest you make it into an extension method.
public static class StringExtensions
{
public static string[] ToStringArray(this string s)
{
if (string.IsNullOrEmpty(s))
return null;
return s.Select(x => x.ToString()).ToArray();
}
}
From the jQuery docs for processData
:
processData Boolean
Default: true
By default, data passed in to the data option as an object (technically, anything other than a string) will be processed and transformed into a query string, fitting to the default content-type "application/x-www-form-urlencoded". If you want to send a DOMDocument, or other non-processed data, set this option to false.
Source: http://api.jquery.com/jquery.ajax
Looks like you are going to have to use processData
to send your data to the server, or modify your php script to support querystring encoded parameters.
Add all your objects to the TreeSet
, you will get a sorted Set. Below is a raw example.
HashSet myHashSet = new HashSet();
myHashSet.add(1);
myHashSet.add(23);
myHashSet.add(45);
myHashSet.add(12);
TreeSet myTreeSet = new TreeSet();
myTreeSet.addAll(myHashSet);
System.out.println(myTreeSet); // Prints [1, 12, 23, 45]
For shared hosting, in cPanel I unchecked the Module in question under "Select PHP Version" > "Extensions" and the error disappeared for PHP 7.4.
You could subscribe for the onkeypress event:
<input type="text" class="textfield" value="" id="extra7" name="extra7" onkeypress="return isNumber(event)" />
and then define the isNumber
function:
function isNumber(evt) {
evt = (evt) ? evt : window.event;
var charCode = (evt.which) ? evt.which : evt.keyCode;
if (charCode > 31 && (charCode < 48 || charCode > 57)) {
return false;
}
return true;
}
You can see it in action here.
You can use stack
from the base package. But, you need first to coerce your matrix to a data.frame
and to reorder the columns once the data is stacked.
mat <- as.data.frame(mat)
res <- data.frame(time= mat$time,stack(mat,select=-time))
res[,c(3,1,2)]
ind time values
1 C_0 0.0 0.1
2 C_0 0.5 0.2
3 C_0 1.0 0.3
4 C_1 0.0 0.3
5 C_1 0.5 0.4
6 C_1 1.0 0.5
Note that stack
is generally more efficient than the reshape2
package.
Yes, this is a clean and neat command to archive your code without any git inclusion in the archive and is good to pass around without worrying about any git commit history.
git archive --format zip --output /full/path/to/zipfile.zip master
You can wrap all tasks which can fail in block, and use ignore_errors: yes
with that block.
tasks:
- name: ls
command: ls -la
- name: pwd
command: pwd
- block:
- name: ls non-existing txt file
command: ls -la no_file.txt
- name: ls non-existing pic
command: ls -la no_pic.jpg
ignore_errors: yes

You ran into Eclipse bug 525948 which has already been fixed and which will be published in the upcoming release Oxygen.3 (4.7.3), March 21, 2018.
As workaround, put your test code in a separate project and add the project under test to the modulepath, but do not add a module-info.java
to your test project. With your project, class and module naming, it should look something like this:

You will certainly be able to do that using WITH clause, or use analytic functions available in Oracle SQL.
With some effort you'd be able to get anything out of them in terms of cycles as in ordinary procedural languages. Both approaches are pretty powerful compared to ordinary SQL.
http://www.dba-oracle.com/t_with_clause.htm
It requires some effort though. Don't be afraid to post a concrete example.
Using simple pseudo table DUAL helps too.
To add to accepted answer: (from apple developer documentation) "When you open the URL built from this string (openSettingsURLString), the system launches the Settings app and displays the app’s custom settings, if it has any." So, if you want to open settings for your app, create your own Settings.bundle.
For Netbeans 7.4 and above in Linux, the cache is $HOME/.cache/netbeans/7.4
.
You can explicitly have a join like this:
$qb->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId');
But you need to use the namespace of the class Join from doctrine:
use Doctrine\ORM\Query\Expr\Join;
Or if you prefere like that:
$qb->innerJoin('c.phones', 'p', Doctrine\ORM\Query\Expr\Join::ON, 'c.id = p.customerId');
Otherwise, Join class won't be detected and your script will crash...
Here the constructor of the innerJoin method:
public function innerJoin($join, $alias, $conditionType = null, $condition = null);
You can find other possibilities (not just join "ON", but also "WITH", etc...) here: http://docs.doctrine-project.org/en/2.0.x/reference/query-builder.html#the-expr-class
EDIT
Think it should be:
$qb->select('c')
->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId')
->where('c.username = :username')
->andWhere('p.phone = :phone');
$qb->setParameters(array(
'username' => $username,
'phone' => $phone->getPhone(),
));
Otherwise I think you are performing a mix of ON and WITH, perhaps the problem.
The first method is the proper approach and will do what you need. However, with the inner joins, you will only select rows from Table1
if both phone numbers exist in Table2
. You may want to do a LEFT JOIN
so that all rows from Table1
are selected. If the phone numbers don't match, then the SomeOtherField
s would be null. If you want to make sure you have at least one matching phone number you could then do WHERE t2.PhoneNumber IS NOT NULL OR t3.PhoneNumber IS NOT NULL
The second method could have a problem: what happens if Table2
has both PhoneNumber1
and PhoneNumber2
? Which row will be selected? Depending on your data, foreign keys, etc. this may or may not be a problem.
A simple restart fixed it for me. I'm not sure what was the problem since I work with so much software but I have a feeling it was the VPN software or maybe the fact I put my laptop in sleep a lot and some file was corrupted. I really don't know but the restart fixed it.
Haskell
foldl (+) 0 [1,2,3,4,5]
Python
reduce(lambda a,b: a+b, [1,2,3,4,5], 0)
Obviously, that is a trivial example to illustrate a point. In Python you would just do sum([1,2,3,4,5])
and even Haskell purists would generally prefer sum [1,2,3,4,5]
.
For non-trivial scenarios when there is no obvious convenience function, the idiomatic pythonic approach is to explicitly write out the for loop and use mutable variable assignment instead of using reduce
or a fold
.
That is not at all the functional style, but that is the "pythonic" way. Python is not designed for functional purists. See how Python favors exceptions for flow control to see how non-functional idiomatic python is.
With the help of bucabay and the advice to create my own function i created this one which works for me. What do you guys think, is there a better solution somewhere?

The best solution I've been able to find consists of these steps:
mvn-repo
to host your maven artifacts.mvn-repo
as a maven repository.There are several benefits to using this approach:
mvn-repo
, much like github pages are kept in a separate branch called gh-pages
(if you use github pages)gh-pages
if you're using them.mvn deploy
as you normally wouldThe typical way you deploy artifacts to a remote maven repo is to use mvn deploy
, so let's patch into that mechanism for this solution.
First, tell maven to deploy artifacts to a temporary staging location inside your target directory. Add this to your pom.xml
:
<distributionManagement>
<repository>
<id>internal.repo</id>
<name>Temporary Staging Repository</name>
<url>file://${project.build.directory}/mvn-repo</url>
</repository>
</distributionManagement>
<plugins>
<plugin>
<artifactId>maven-deploy-plugin</artifactId>
<version>2.8.1</version>
<configuration>
<altDeploymentRepository>internal.repo::default::file://${project.build.directory}/mvn-repo</altDeploymentRepository>
</configuration>
</plugin>
</plugins>
Now try running mvn clean deploy
. You'll see that it deployed your maven repository to target/mvn-repo
. The next step is to get it to upload that directory to GitHub.
Add your authentication information to ~/.m2/settings.xml
so that the github site-maven-plugin
can push to GitHub:
<!-- NOTE: MAKE SURE THAT settings.xml IS NOT WORLD READABLE! -->
<settings>
<servers>
<server>
<id>github</id>
<username>YOUR-USERNAME</username>
<password>YOUR-PASSWORD</password>
</server>
</servers>
</settings>
(As noted, please make sure to chmod 700 settings.xml
to ensure no one can read your password in the file. If someone knows how to make site-maven-plugin prompt for a password instead of requiring it in a config file, let me know.)
Then tell the GitHub site-maven-plugin
about the new server you just configured by adding the following to your pom:
<properties>
<!-- github server corresponds to entry in ~/.m2/settings.xml -->
<github.global.server>github</github.global.server>
</properties>
Finally, configure the site-maven-plugin
to upload from your temporary staging repo to your mvn-repo
branch on Github:
<build>
<plugins>
<plugin>
<groupId>com.github.github</groupId>
<artifactId>site-maven-plugin</artifactId>
<version>0.11</version>
<configuration>
<message>Maven artifacts for ${project.version}</message> <!-- git commit message -->
<noJekyll>true</noJekyll> <!-- disable webpage processing -->
<outputDirectory>${project.build.directory}/mvn-repo</outputDirectory> <!-- matches distribution management repository url above -->
<branch>refs/heads/mvn-repo</branch> <!-- remote branch name -->
<includes><include>**/*</include></includes>
<repositoryName>YOUR-REPOSITORY-NAME</repositoryName> <!-- github repo name -->
<repositoryOwner>YOUR-GITHUB-USERNAME</repositoryOwner> <!-- github username -->
</configuration>
<executions>
<!-- run site-maven-plugin's 'site' target as part of the build's normal 'deploy' phase -->
<execution>
<goals>
<goal>site</goal>
</goals>
<phase>deploy</phase>
</execution>
</executions>
</plugin>
</plugins>
</build>
The mvn-repo
branch does not need to exist, it will be created for you.
Now run mvn clean deploy
again. You should see maven-deploy-plugin "upload" the files to your local staging repository in the target directory, then site-maven-plugin committing those files and pushing them to the server.

Visit github.com in your browser, select the mvn-repo
branch, and verify that all your binaries are now there.
Congratulations!
You can now deploy your maven artifacts to a poor man's public repo simply by running mvn clean deploy
.
There's one more step you'll want to take, which is to configure any poms that depend on your pom to know where your repository is. Add the following snippet to any project's pom that depends on your project:
<repositories>
<repository>
<id>YOUR-PROJECT-NAME-mvn-repo</id>
<url>https://github.com/YOUR-USERNAME/YOUR-PROJECT-NAME/raw/mvn-repo/</url>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>
</repositories>
Now any project that requires your jar files will automatically download them from your github maven repository.
Edit: to avoid the problem mentioned in the comments ('Error creating commit: Invalid request. For 'properties/name', nil is not a string.'), make sure you state a name in your profile on github.
Try this code. Call it before making any http requests. The code will use the proxy from your Internet Explorer Settings - one thing though, I use proxy.Credentials = ....
because my proxy server is an NTLM authenticated Internet Acceleration Server. Give it a whizz.
static void setProxy()
{
WebProxy proxy = (WebProxy)WebProxy.GetDefaultProxy();
if(proxy.Address != null)
{
proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
WebRequest.DefaultWebProxy = new System.Net.WebProxy(proxy.Address, proxy.BypassProxyOnLocal, proxy.BypassList, proxy.Credentials);
}
}

You have to put div with single quotation around it. ' '
the Div
must be in the middle of single quotation . i'm gonna clear it with one example :
<?php
echo '<div id="output">'."Identify".'<br>'.'<br>';
echo 'Welcome '."$name";
echo "<br>";
echo 'Web Mail: '."$email";
echo "<br>";
echo 'Department of '."$dep";
echo "<br>";
echo "$maj";
'</div>'
?>
hope be useful.
UPDATE:
Use the UIButtonBackgroundColor Swift library.
OLD:
Use the helpers below to create a 1 px x 1 px image with a grayscale fill color:
UIImage *image = ACUTilingImageGray(248/255.0, 1);
or an RGB fill color:
UIImage *image = ACUTilingImageRGB(253/255.0, 123/255.0, 43/255.0, 1);
Then, use that image
to set the button's background image:
[button setBackgroundImage:image forState:UIControlStateNormal];
#pragma mark - Helpers
UIImage *ACUTilingImageGray(CGFloat gray, CGFloat alpha)
{
return ACUTilingImage(alpha, ^(CGContextRef context) {
CGContextSetGrayFillColor(context, gray, alpha);
});
}
UIImage *ACUTilingImageRGB(CGFloat red, CGFloat green, CGFloat blue, CGFloat alpha)
{
return ACUTilingImage(alpha, ^(CGContextRef context) {
CGContextSetRGBFillColor(context, red, green, blue, alpha);
});
}
UIImage *ACUTilingImage(CGFloat alpha, void (^setFillColor)(CGContextRef context))
{
CGRect rect = CGRectMake(0, 0, 0.5, 0.5);
UIGraphicsBeginImageContextWithOptions(rect.size, alpha == 1, 0);
CGContextRef context = UIGraphicsGetCurrentContext();
setFillColor(context);
CGContextFillRect(context, rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
Note: ACU
is the class prefix of my Cocoa Touch Static Library called Acani Utilities, where AC is for Acani, and U is for Utilities.
here is my basic class in python for the requests module with some proxy configs and stopwatch !

class BaseCheck():
def __init__(self, url):
self.http_proxy = "http://user:pw@proxy:8080"
self.https_proxy = "http://user:pw@proxy:8080"
self.ftp_proxy = "http://user:pw@proxy:8080"
self.proxyDict = {
"http" : self.http_proxy,
"https" : self.https_proxy,
"ftp" : self.ftp_proxy
}
self.url = url
def makearr(tsteps):
global stemps
global steps
stemps = {}
for step in tsteps:
stemps[step] = { 'start': 0, 'end': 0 }
steps = tsteps
makearr(['init','check'])
def starttime(typ = ""):
for stemp in stemps:
if typ == "":
stemps[stemp]['start'] = time.time()
else:
stemps[stemp][typ] = time.time()
starttime()
def __str__(self):
return str(self.url)
def getrequests(self):
g=requests.get(self.url,proxies=self.proxyDict)
print g.status_code
print g.content
print self.url
stemps['init']['end'] = time.time()
#print stemps['init']['end'] - stemps['init']['start']
x= stemps['init']['end'] - stemps['init']['start']

maybe its better using the case
instead of if
dunno if this eliminates the error, but its cleaner i think.. switch (operation){case +: System.out.println("your answer is" + (num1 + num2));break;case -: System.out.println("your answer is" - (num1 - num2));break; ...
Easy workaround that I always use
let list = document.getElementsByClassName("events");
let listArr = Array.from(list)
After this you can run any desired Array methods on the selection
listArr.map(item => console.log(item.id))
listArr.forEach(item => console.log(item.id))
listArr.reverse()
For those coming in 2018:
The ONLY Solution worked for me:
<?php
if (ob_get_level() == 0) ob_start();
for ($i = 0; $i<10; $i++){
echo "<br> Line to show.";
echo str_pad('',4096)."\n";
ob_flush();
flush();
sleep(2);
}
echo "Done.";
ob_end_flush();
?>
and its very important to keep de "4096" part because it seems that "fills" the buffer...
The best way its add:
<ImageView
android:id="@+id/ivBack"
style="?attr/actionButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="16dp"
android:src="@drawable/ic_back_arrow_black"
android:tint="@color/white" />
SOA records are present on all servers further up the hierarchy, over which the domain owner has NO control, and they all in effect point to the one authoritative name server under control of the domain owner.
The SOA record on the authoritative server itself is, on the other hand, not strictly needed for resolving that domain, and can contain bogus info (or hidden primary, or otherwise restricted servers) and should not be relied on to determine the authoritative name server for a given domain.
You need to query the server that is authoritative for the top level domain to obtain reliable SOA information for a given child domain.
(The information about which server is authoritative for which TLD can be queried from the root name servers).
When you have reliable information about the SOA from the TLD authoritative server, you can then query the primary name server itself authoritative (the one thats in the SOA record on the gTLD nameserver!) for any other NS records, and then proceed with checking all those name servers you've got from querying the NS records, to see if there is any inconsistency for any other particular record, on any of those servers.
This all works much better/reliable with linux and dig than with nslookup/windows.
Option 1 : Split email address into multiple parts and create an array in JavaScript out of these parts. Next join these parts in the correct order and use the .innerHTML property to add the email address to the web page.
<span id="email"> </span> // blank tag
<script>
var parts = ["info", "XXXXabc", "com", ".", "@"];
var email = parts[0] + parts[4] + parts[1] + parts[3] + parts[2];
document.getElementById("email").innerHTML=email;
</script>
Option 2 : Use image instead of email text
Image creator website from text : http://www.chxo.com/labelgen/
Option 3 : We can use AT instead of "@" and DOT instead of " . "
i.e :
info(AT)XXXabc(DOT)com
Best way i use:
1- add link to your html:
<a id="linkDynamic" target="_blank" href="#"></a>
2- add JS function:
function OpenNewTab(href)
{
document.getElementById('linkDynamic').href = href;
document.getElementById('linkDynamic').click();
}
3- just call OpenNewTab function with the link you want

DEBUG is the lowest restricted java logging level and we should write everything we need to debug an application, this java logging mode should only be used on Development and Testing environment and must not be used in production environment.
INFO is more restricted than DEBUG java logging level and we should log messages which are informative purpose like Server has been started, Incoming messages, outgoing messages etc in INFO level logging in java.
WARN is more restricted than INFO java logging level and used to log warning sort of messages e.g. Connection lost between client and server. Database connection lost, Socket reaching to its limit. These messages and java logging level are almost important because you can setup alert on these logging messages in java and let your support team monitor health of your java application and react on this warning messages. In Summary WARN level is used to log warning message for logging in Java.
ERROR is the more restricted java logging level than WARN and used to log Errors and Exception, you can also setup alert on this java logging level and alert monitoring team to react on this messages. ERROR is serious for logging in Java and you should always print it.
FATAL java logging level designates very severe error events that will presumably lead the application to abort. After this mostly your application crashes and stopped.
OFF java logging level has the highest possible rank and is intended to turn off logging in Java.
Use Keytool binary or exe to generate a private keystore. Instructions here. You can then sign your app using this keystore. Keytool gets installed when you install Java.
NOTE: Save/backup this keystore because once you publish an app on play by signing it with this keystore, you will have to use the same keystore for any future updates. So, it's important that you back it up.
HTH.
or you can inject the class inheritance "http" into React Component
via props object.
update :
ReactDOM.render(<ReactApp data={app} />, document.getElementById('root'));
Simply edit React Component ReactApp like this:
class ReactApp extends React.Component {
state = {
data: ''
}
render(){
return (
<div>
{this.props.data.getData()}
</div>
)
}
}
In cordova 6.2.0
cd cordova/ #change to root cordova folder
platforms/android/cordova/clean #clean if you want
cordova build android --release -- --keystore="/path/to/keystore" --storePassword=password --alias=alias_name #password will be prompted if you have any
Previous answer:
According to cordova 5.0.0
{
"android": {
"release": {
"keystore": "app-release-key.keystore",
"alias": "alias_name"
}
}
}
and run ./build --release --buildConfig build.json
from directory platforms/android/cordova/
keystore file location is relative to platforms/android/cordova/
, so in above configuration .keystore
file and build.json
are in same directory.
keytool -genkey -v -keystore app-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
In my makefile I use this:
@sed -i '/.*Revision:.*/c\'"`svn info -R main.cpp | awk '/^Rev/'`"'' README.md
PS: DO NOT forget that the -i changes actually the text in the file... so if the pattern you defined as "Revision" will change, you will also change the pattern to replace.
Example output:
Abc-Project written by John Doe
Revision: 1190
So if you set the pattern "Revision: 1190" it's obviously not the same as you defined them as "Revision:" only...
I used the url as above: http://translate.google.com/translate_tts?tl=en&q=Hello%20World
And requested with python library..however I'm getting HTTP 403 FORBIDDEN
In the end I had to mock the User-Agent
header with the browser's one to succeed.
>>> import random
>>> a = ['hi','world','cat','dog']
>>> random.shuffle(a,random.random)

['hi', 'cat', 'dog', 'world']
It works fine for me. Make sure to set the random method.
Yes, in C# 6.0 -- https://msdn.microsoft.com/en-us/magazine/dn802602.aspx.
object?.SomeMethod()
Possible Cause for this error:
You can also check this how to guide on eclipse remote debugging for more details.
I also faced similar problem.If you have already reserved url then you have to first delete the url to run in non admin mode else it will fail with Access is Denied error.
netsh http delete urlacl url=http://+:80
What about initializing a variable at the top of the class with a default value? For example:
public class SomeClass {
private int maxRows = 15000;
...
// Inside another method
for (int i = 0; i < maxRows; i++) {
// Do something
}
public void setMaxRows(int maxRows) {
this.maxRows = maxRows;
}
public int getMaxRows() {
return this.maxRows;
}
In this case, 15000 is a magic number (according to CheckStyles). To me, setting a default value is okay. I don't want to have to do:
private static final int DEFAULT_MAX_ROWS = 15000;
private int maxRows = DEFAULT_MAX_ROWS;
Does that make it more difficult to read? I never considered this until I installed CheckStyles.
using System.Windows.Media;
byte R = Convert.ToByte(color.Substring(1, 2), 16);
byte G = Convert.ToByte(color.Substring(3, 2), 16);
byte B = Convert.ToByte(color.Substring(5, 2), 16);
SolidColorBrush scb = new SolidColorBrush(Color.FromRgb(R, G, B));
//applying the brush to the background of the existing Button btn:
btn.Background = scb;

My problem was with Google Chrome cache. I tested this by running my web application on Firefox and I didn't got that error there. So then I decided trying emptying cache of Google Chrome and it worked.
The directory or a file in it is locked and cannot be deleted. Find the culprit who locks it and see if you can eliminate it.
You can easily create a Stream
out of an Iterable
or Iterator
:
public static <T> Stream<T> stream(Iterable<T> iterable) {
return StreamSupport.stream(
Spliterators.spliteratorUnknownSize(
iterable.iterator(),
Spliterator.ORDERED
),
false
);
}
From the spec:
All characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark (U+0022), reverse solidus [backslash] (U+005C), and the control characters U+0000 to U+001F
Just because e.g. Bell (U+0007) doesn't have a single-character escape code does not mean that you don't need to escape it. Use the Unicode escape sequence \u0007
.
Had similar message
Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'. More than one file was found with OS independent path 'constant-values.html'
To resolve it, I had to enable packages view(1) in Android Studio, then browse through the tree to libraries, and locate the duplicates(2)
Then, ctrl+alt+f12 (or RMB menu)(3) - and found libraries which caused the issue. Made list of files inside those libs which caused the issues, and wrote them to app's build.gradle file inside android section. Other option is to deal with the library, containing duplicate files

HTTPS IS NOW SUPPORTED
While my answer below detailing how-to for each service WILL work, IMO it's much easier now to go with a third-party like AddThisEvent [https://addthisevent.com]. It lets you customize lots of options as well as add to Facebook and more. Unfortunately, they've now made it a paid service for anything other than personal use and do enforce this.
I assume there are other third-party solutions like this one, but I can only speak to this one, and it has worked great for us so far.
For an "Add to my Google Calendar", they used to have a code generator form you could use, but have since taken it down. For more details on Google Calendar links, see squarecandy's answer below.
For Outlook, it's a BIT more complicated, but basically you need to create a .vcs
file with the event's data, and just make a link to that file. Step-by-step instructions here.
For an iCal link, you could use a PHP class like this one, or follow this page's instructions on how to create an ics
file (iCal file).

I have written an application using WPF, Prism and MVVM to simulate hiring a cab, you can read about it on my blog, download the source here and play with it.
To anyone reading this in 2017, this is how I've done something similar.

on pets_activities.id = pets.id WHERE pets.`order` > :order AND
pets.`pet_id` = :pet_id
Generally, to delete rows from multiple tables, the syntax I follow is given below. The solution is based on an assumption that there is some relation between the two tables.
DELETE table1, table2 FROM table1 inner join table2 on table2.id = table1.id

newStream.Write(data, 0, data.Length);
newStream.Close();
Not really. Internally, passing by reference is performed by essentially passing the address of the referenced object. So, there really aren't any efficiency gains to be had by passing a pointer.
Passing by reference does have one benefit, however. You are guaranteed to have an instance of whatever object/type that is being passed in. If you pass in a pointer, then you run the risk of receiving a NULL pointer. By using pass-by-reference, you are pushing an implicit NULL-check up one level to the caller of your function.
Thanks for the information. very helpful i used it for locking page interaction while in edit mode by another user. I used it in conjunction with ajaxComplete. Not necesarily the same behavior but somewhat similar.
function userPageLock(){
$("body").bind("ajaxComplete.lockpage", function(){
$("body").unbind("ajaxComplete.lockpage");
executePageLock();
});
};
function executePageLock(){
//do something
}
You can define:
Context ctx;
And on onCreate
initialise ctx
to:
ctx=parent.getContext();
Note: Parent is a ViewGroup.
MSVS requires you to specify which symbols to export and import using __declspec(dllexport)
and __declspec(dllimport)
.
This dual functionality is usually obtained through the use of a macro:
#ifdef THIS_MODULE
#define DLLIMPEXP __declspec(dllexport)
#else
#define DLLIMPEXP __declspec(dllimport)
#endif
The macro THIS_MODULE
would only be defined in the module that exports the function. That way, the declaration:
DLLIMPEXP void foo();
expands to
__declspec(dllexport) void foo();
and tells the compiler to export the function, as the current module contains its definition. When including the declaration in a different module, it would expand to
__declspec(dllimport) void foo();
and tells the compiler that the definition is in one of the libraries you linked against (also see 1)).
You can similary import/export classes:
class DLLIMPEXP X
{
};
@Comment for ID:14. It's for me rather easier to write:
out.append it
instead of
out.println it
println did on my machine only write the first file of the ArrayList, with append I get the whole List written into the file.
Kindly anyway for the quick-and-dirty-solution.
Follow below steps-
Step1 - Ctrl+Shift+P
Step2 - Enter Disable Package
Step3 - enter the package name that you want to disable and press enter

You should use a SQL tool to visualize possbile errors like MySQL Workbench.
The best way I've found to do this is with StrMethodFormatter
:
import matplotlib as mpl
ax.yaxis.set_major_formatter(mpl.ticker.StrMethodFormatter('{x:,.0f}'))
For example:
import pandas as pd
import requests
import matplotlib.pyplot as plt
import matplotlib as mpl
url = 'https://min-api.cryptocompare.com/data/histoday?fsym=BTC&tsym=USDT&aggregate=1'
df = pd.DataFrame({'BTC/USD': [d['close'] for d in requests.get(url).json()['Data']]})
ax = df.plot()
ax.yaxis.set_major_formatter(mpl.ticker.StrMethodFormatter('{x:,.0f}'))
plt.show()
Ensure you have set the name for your ComboBox in your XAML file:
<ComboBox Height="23" Name="comboBox" />
In your code you can access selected item using SelectedItem
property:
MessageBox.Show(comboBox.SelectedItem.ToString());
I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.
In your class AutoMapper
profile, you need to create a map for your entity and viewmodel.
This is usually in AutoMapper/DomainToViewModelMappingProfile
In Configure()
, add a line like
Mapper.CreateMap<YourEntityViewModel, YourEntity>();
In ViewModelToDomainMappingProfile
, add:
Mapper.CreateMap<YourEntity, YourEntityViewModel>();
Try pass array to vector:
int arr[] = {2,5,8,11,14};
std::vector<int> TestVector(arr, arr+5);
You could always call std::vector::assign to assign array to vector, call std::vector::insert to add multiple arrays.
If you use C++11, you can try:
std::vector<int> v{2,5,8,11,14};
Or
std::vector<int> v = {2,5,8,11,14};
IMHO Lookup tables is the way to go, with referential integrity. But only if you avoid "Evil Magic Numbers" by following an example such as this one: Generate enum from a database lookup table using T4
Have Fun!
If you are using the updated Microsoft.Web.RedisSessionStateProvider
(starting from 3.0.2
) you can add this to your web.config
to allow concurrent sessions.
<appSettings>
<add key="aspnet:AllowConcurrentRequestsPerSession" value="true"/>
</appSettings>
class Program
{
private static int[] table;
static void Main(string[] args)
{
int[] ints = new int[] { 6, 2, 5, 99, 55 };
table = ints.OrderByDescending(x => x).ToArray();
foreach (var item in table)
{
Console.WriteLine(item);
}
}
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same timeThis will show you clues about why the linker doesn't want the installed library:
LD_DEBUG=all make ...
I had the same problem in a different context: my system /lib/libz.so.1 had unsatisfied dependencies on libc because I was trying to relink on a different version of the OS.
In my sample code, I was setting my object
to nothing, and I couldn't get the "not" part of the if statement to work with the object. I tried if My_Object is not nothing
and also if not My_Object is nothing
. It may be just a syntax thing I can't figure out but I didn't have time to mess around, so I did a little workaround like this:
if My_Object is Nothing Then
'do nothing
Else
'Do something
End if
You may be tempted to use (*)
but what if a directory contains the *
character? It's very difficult to handle special characters in filenames correctly.
You can use ls -ls
. However, it fails to handle newline characters.
# Store la -ls as an array
readarray -t files <<< $(ls -ls)
for (( i=1; i<${#files[@]}; i++ ))
{
# Convert current line to an array
line=(${files[$i]})
# Get the filename, joining it together any spaces
fileName=${line[@]:9}
echo $fileName
}
If all you want is the file name, then just use ls
:
for fileName in $(ls); do
echo $fileName
done
See this article or this this post for more information about some of the difficulties of dealing with special characters in file names.
It's not clear how you want your Date logic to behave? Usually a good way to deal with default behaviour is the Null Object pattern.
This should work:
dists[((dists >= r) & (dists <= r+dr))]
The most elegant way~~
Having just messed around with this, it's useful to kjnow that the e.X / e.Y points are relative to the control, so if (as I was) you are adding a context menu to a listview or something similar, you will want to adjust it with the form's origin. In the example below I've added 20 to the x/y so that the menu appears slightly to the right and under the cursor.
cmDelete.Show(this, new Point(e.X + ((Control)sender).Left+20, e.Y + ((Control)sender).Top+20));
The bug you reference (bug 4787391) has been fixed in Java 8. Even if you are using an older version of Java, the System.getProperty("user.home")
approach is probably still the best. The user.home
approach seems to work in a very large number of cases. A 100% bulletproof solution on Windows is hard, because Windows has a shifting concept of what the home directory means.
If user.home
isn't good enough for you I would suggest choosing a definition of home directory
for windows and using it, getting the appropriate environment variable with System.getenv(String)
.

As a string, no. As an integer, %d.
Unless you count:
static char* enumStrings[] = { /* filler 0's to get to the first value, */
"enum0", "enum1",
/* filler for hole in the middle: ,0 */
"enum2", "enum3", .... };
...
printf("The value is %s\n", enumStrings[thevalue]);
This won't work for something like an enum of bit masks. At that point, you need a hash table or some other more elaborate data structure.
v4l support has been dropped in recent kernel versions (including the one shipped with Ubuntu 11.04).
EDIT: Your question is connected to a recent message that was sent to the OpenCV users group, which has instructions to compile OpenCV 2.2 in Ubuntu 11.04. Your approach is not ideal.
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
Intent shareIntent = Intent.createChooser(sendIntent, null);
startActivity(shareIntent);
This has been fixed in Bootstrap v4.1 and above by adding data-boundary="viewport"
(Bootstrap Dropdowns Docs)
But for earlier versions (v4.0 and below), I found this javascript snippet that works perfectly. It works for small tables and scrolling tables:
$('.table-responsive').on('shown.bs.dropdown', function (e) {
var t = $(this),
m = $(e.target).find('.dropdown-menu'),
tb = t.offset().top + t.height(),
mb = m.offset().top + m.outerHeight(true),
d = 20; // Space for shadow + scrollbar.
if (t[0].scrollWidth > t.innerWidth()) {
if (mb + d > tb) {
t.css('padding-bottom', ((mb + d) - tb));
}
}
else {
t.css('overflow', 'visible');
}
}).on('hidden.bs.dropdown', function () {
$(this).css({'padding-bottom': '', 'overflow': ''});
});
You can use header files.
Good practice.
You can create a file called player.h
declare all functions that are need by other cpp files in that header file and include it when needed.
player.h
#ifndef PLAYER_H // To make sure you don't declare the function more than once by including the header multiple times.
#define PLAYER_H
#include "stdafx.h"
#include <SFML/Graphics.hpp>
int playerSprite();
#endif
player.cpp
#include "player.h" // player.h must be in the current directory. or use relative or absolute path to it. e.g #include "include/player.h"
int playerSprite(){
sf::Texture Texture;
if(!Texture.loadFromFile("player.png")){
return 1;
}
sf::Sprite Sprite;
Sprite.setTexture(Texture);
return 0;
}
main.cpp
#include "stdafx.h"
#include <SFML/Graphics.hpp>
#include "player.h" //Here. Again player.h must be in the current directory. or use relative or absolute path to it.
int main()
{
// ...
int p = playerSprite();
//...
Not such a good practice but works for small projects. declare your function in main.cpp
#include "stdafx.h"
#include <SFML/Graphics.hpp>
// #include "player.cpp"
int playerSprite(); // Here
int main()
{
// ...
int p = playerSprite();
//...
