The haversine is definitely a good formula for probably most cases, other answers already include it so I am not going to take the space. But it is important to note that no matter what formula is used (yes not just one). Because of the huge range of accuracy possible as well as the computation time required. The choice of formula requires a bit more thought than a simple no brainer answer.
This posting from a person at nasa, is the best one I found at discussing the options
http://www.cs.nyu.edu/visual/home/proj/tiger/gisfaq.html
For example, if you are just sorting rows by distance in a 100 miles radius. The flat earth formula will be much faster than the haversine.
HalfPi = 1.5707963;
R = 3956; /* the radius gives you the measurement unit*/
a = HalfPi - latoriginrad;
b = HalfPi - latdestrad;
u = a * a + b * b;
v = - 2 * a * b * cos(longdestrad - longoriginrad);
c = sqrt(abs(u + v));
return R * c;
Notice there is just one cosine and one square root. Vs 9 of them on the Haversine formula.
You can try the following:
from haversine import haversine
haversine((45.7597, 4.8422),(48.8567, 2.3508), unit='mi')
243.71209416020253
I found this code which is giving me reliable results.
function distance($lat1, $lon1, $lat2, $lon2, $unit) {
$theta = $lon1 - $lon2;
$dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta));
$dist = acos($dist);
$dist = rad2deg($dist);
$miles = $dist * 60 * 1.1515;
$unit = strtoupper($unit);
if ($unit == "K") {
return ($miles * 1.609344);
} else if ($unit == "N") {
return ($miles * 0.8684);
} else {
return $miles;
}
}
results :
echo distance(32.9697, -96.80322, 29.46786, -98.53506, "M") . " Miles<br>";
echo distance(32.9697, -96.80322, 29.46786, -98.53506, "K") . " Kilometers<br>";
echo distance(32.9697, -96.80322, 29.46786, -98.53506, "N") . " Nautical Miles<br>";
Postman is a good solution and so is php fiddle. However to avoid putting in the GCM URL and the header information every time, you can also use this nifty GCM Notification Test Tool
The Union method might address your needs. You didn't specify whether order or duplicates was important.
Take two IEnumerables and perform a union as seen here:
int[] ints1 = { 5, 3, 9, 7, 5, 9, 3, 7 };
int[] ints2 = { 8, 3, 6, 4, 4, 9, 1, 0 };
IEnumerable<int> union = ints1.Union(ints2);
// yields { 5, 3, 9, 7, 8, 6, 4, 1, 0 }
This is a feature, not a bug.
See http://docs.python.org/howto/unicode.html, specifically the 'unicode type' section.
Why not store the function itself? myvar = mypackage.mymodule.myfunction
is much cleaner.
You can apply the style via javascript. This is the Js code below that applies the filter to the image with the ID theImage.
function invert(){
document.getElementById("theImage").style.filter="invert(100%)";
}
And this is the
<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png"></img>
Now all you need to do is call invert() We do this when the image is clicked.
function invert(){_x000D_
document.getElementById("theImage").style.filter="invert(100%)";_x000D_
}
_x000D_
<h4> Click image to invert </h4>_x000D_
_x000D_
<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png" onClick="invert()" ></img>
_x000D_

Who wants to try with generators?
Step 1: Click on Global.asax File in your Solution.
Step 2: Then Go to Definition of
RouteConfig.RegisterRoutes(RouteTable.Routes);
Step 3: Change Controller Name and View Name
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home",
action = "Index",
id = UrlParameter.Optional }
);
}
}
Use IS NULL
or IS NOT NULL
in WHERE-clause instead of ISNULL() method:
SELECT myField1
FROM myTable1
WHERE myField1 IS NOT NULL
If you want to find the first day and last day from the specified date variable then you can do this like below:
$date = '2012-02-12';//your given date
$first_date_find = strtotime(date("Y-m-d", strtotime($date)) . ", first day of this month");
echo $first_date = date("Y-m-d",$first_date_find);
$last_date_find = strtotime(date("Y-m-d", strtotime($date)) . ", last day of this month");
echo $last_date = date("Y-m-d",$last_date_find);
For the current date just simple use this
$first_date = date('Y-m-d',strtotime('first day of this month'));
$last_date = date('Y-m-d',strtotime('last day of this month'));
<a href="#" (click)="foo(); false">
<a href="" (click)="false">
In Solution Explorer, please select files you want to copied to output directory and assign two properties: - Build action = Content - Copy to Output Directory = Copy Always
This will do the trick.
As of now there is just two property for firefox scrollbar customization is available .
scrollbar-color & scrollbar width
scrollbar-color:red yellow; (track,thumb) scrollbar-width:5px;
HTML
<div class="demo">
css
.demo {
overflow-y:scroll;
}
.demo {
scrollbar-color:red yellow;
scrollbar-width:5px;
}
You can also check if you have an empty string as argument so you can call like:
foo('blah', "", 'non-default y value', null);
Below the function:
function foo($blah, $x = null, $y = null, $z = null) {
if (null === $x || "" === $x) {
$x = "some value";
}
if (null === $y || "" === $y) {
$y = "some other value";
}
if (null === $z || "" === $z) {
$z = "some other value";
}
code here!
}
It doesn't matter if you fill null
or ""
, you will still get the same result.
Just use the -fno-objc-arc flag in Build Phases>Compile Sources infront of files to whom you dont want ARC to be apply.
Just check in you projects properties >build ->packaging WAR file compress.
another solution, cut the string in 2 and put a string in between.
var str = jQuery('#selector').text();
var strlength = str.length;
strf = str.substr(0 , strlength - 5);
strb = str.substr(strlength - 5 , 5);
jQuery('#selector').html(strf + 'inserted' + strb);
I encountered the same problem and solved it by
git checkout -f branch
Well, be careful with the -f
switch. You will lose any uncommitted changes if you use the -f
switch. While there may be some use cases where it is helpful to use -f
, in most cases, you may want to stash
your changes and then switch
branches. The stashing
procedure is explained above.

The easier one for newbies:
Button button = new Button();
button.Click += new EventHandler(button_Click);
protected void button_Click (object sender, EventArgs e)
{
Button button = sender as Button;
// identify which button was clicked and perform necessary actions
}
Because you are asking the compiler to initialize a static variable with code that is inherently dynamic.
if you provide a bad path or a broken link, if the compiler cannot find the image, the picture box would display an X icon on its body.
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
Image = Image.FromFile(@"c:\Images\test.jpg"),
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
OR
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
ImageLocation = @"c:\Images\test.jpg",
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
i'm not sure where you put images in your folder structure but you can find the path as bellow
picture.ImageLocation = Path.Combine(System.Windows.Forms.Application.StartupPath, "Resources\Images\1.jpg");
You can do like this using function:
l = [34,56,78,2,3,5,6,8,45,6]
print ("The list : " + str(l))
def count_greater30(l):
count = 0
for i in l:
if i > 30:
count = count + 1.
return count
print("Count greater than 30 is : " + str(count)).
count_greater30(l)

You can use ES6 to import package.json to retrieve version number and output the version on console.
import {name as app_name, version as app_version} from './path/to/package.json';
console.log(`App ---- ${app_name}\nVersion ---- ${app_version}`);
I'd like to show another option I used to get the same result as the answers before provide, I had a similar case where I wanted to backup android studio projects all together in a tar file to upload to media fire, using the du command to find the large files, I found that I didn't need some directories like: build, linux e .dart_tools Using the first answer of Charles_ma I modified it a little bit to be able to run the command from the parent directory of the my Android directory.
tar --exclude='*/build' --exclude='*/linux' --exclude='*/.dart_tool' -zcvf androidProjects.tar Android/
It worked like a charm.
Ps. Sorry if this kind of answer is not allowed, if this is the case I will remove.
For new projects, I've started having every class I write extend the same base class where I can put all the utility methods that are annoyingly missing from Java like this one, the equivalent for collections (tired of writing list != null && ! list.isEmpty()), null-safe equals, etc. I still use Apache Commons for the implementation but this saves a small amount of typing and I haven't seen any negative effects.
This could be useful. Like another answer it is just CSS.

word-wrap: break-word;

querySelectorAll returns a NodeList which has its own forEach method:
document.querySelectorAll('input').forEach( input => {
// ...
});
getElementsByTagName now returns an HTMLCollection instead of a NodeList. So you would first need to convert it to an array to have access to methods like map and forEach:
Array.from(document.getElementsByTagName('input')).forEach( input => {
// ...
});
You can turn the color picker into an application by following the guide here:

One of the best explanation of lambda expression
is given from author of C++ Bjarne Stroustrup in his book ***The C++ Programming Language***
chapter 11 (ISBN-13: 978-0321563842):
What is a lambda expression?
A lambda expression, sometimes also referred to as a lambda function or (strictly speaking incorrectly, but colloquially) as a lambda, is a simplified notation for defining and using an anonymous function object. Instead of defining a named class with an operator(), later making an object of that class, and finally invoking it, we can use a shorthand.
When would I use one?
This is particularly useful when we want to pass an operation as an argument to an algorithm. In the context of graphical user interfaces (and elsewhere), such operations are often referred to as callbacks.
What class of problem do they solve that wasn't possible prior to their introduction?
Here i guess every action done with lambda expression can be solved without them, but with much more code and much bigger complexity. Lambda expression this is the way of optimization for your code and a way of making it more attractive. As sad by Stroustup :
effective ways of optimizing
Some examples
via lambda expression
void print_modulo(const vector<int>& v, ostream& os, int m) // output v[i] to os if v[i]%m==0
{
for_each(begin(v),end(v),
[&os,m](int x) {
if (x%m==0) os << x << '\n';
});
}
or via function
class Modulo_print {
ostream& os; // members to hold the capture list int m;
public:
Modulo_print(ostream& s, int mm) :os(s), m(mm) {}
void operator()(int x) const
{
if (x%m==0) os << x << '\n';
}
};
or even
void print_modulo(const vector<int>& v, ostream& os, int m)
// output v[i] to os if v[i]%m==0
{
class Modulo_print {
ostream& os; // members to hold the capture list
int m;
public:
Modulo_print (ostream& s, int mm) :os(s), m(mm) {}
void operator()(int x) const
{
if (x%m==0) os << x << '\n';
}
};
for_each(begin(v),end(v),Modulo_print{os,m});
}
if u need u can name lambda expression
like below:
void print_modulo(const vector<int>& v, ostream& os, int m)
// output v[i] to os if v[i]%m==0
{
auto Modulo_print = [&os,m] (int x) { if (x%m==0) os << x << '\n'; };
for_each(begin(v),end(v),Modulo_print);
}
Or assume another simple sample
void TestFunctions::simpleLambda() {
bool sensitive = true;
std::vector<int> v = std::vector<int>({1,33,3,4,5,6,7});
sort(v.begin(),v.end(),
[sensitive](int x, int y) {
printf("\n%i\n", x < y);
return sensitive ? x < y : abs(x) < abs(y);
});
printf("sorted");
for_each(v.begin(), v.end(),
[](int x) {
printf("x - %i;", x);
}
);
}
will generate next

- this is capture list or lambda introducer
: if lambdas
require no access to their local environment we can use it.
Quote from book:
The first character of a lambda expression is always [. A lambda introducer can take various forms:
• []: an empty capture list. This implies that no local names from the surrounding context can be used in the lambda body. For such lambda expressions, data is obtained from arguments or from nonlocal variables.
• [&]: implicitly capture by reference. All local names can be used. All local variables are accessed by reference.
• [=]: implicitly capture by value. All local names can be used. All names refer to copies of the local variables taken at the point of call of the lambda expression.
• [capture-list]: explicit capture; the capture-list is the list of names of local variables to be captured (i.e., stored in the object) by reference or by value. Variables with names preceded by & are captured by reference. Other variables are captured by value. A capture list can also contain this and names followed by ... as elements.
• [&, capture-list]: implicitly capture by reference all local variables with names not men- tioned in the list. The capture list can contain this. Listed names cannot be preceded by &. Variables named in the capture list are captured by value.
• [=, capture-list]: implicitly capture by value all local variables with names not mentioned in the list. The capture list cannot contain this. The listed names must be preceded by &. Vari- ables named in the capture list are captured by reference.
Note that a local name preceded by & is always captured by reference and a local name not pre- ceded by & is always captured by value. Only capture by reference allows modification of variables in the calling environment.
Additional
Lambda expression
format
Additional references:
For the 24-hour time, you need to use HH24
instead of HH
.
For the 12-hour time, the AM/PM indicator is written as A.M.
(if you want periods in the result) or AM
(if you don't). For example:
SELECT invoice_date,
TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
FROM invoices
;
For more information on the format models you can use with TO_CHAR
on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.
The raiserror method
raiserror('Oh no a fatal error', 20, -1) with log
This will terminate the connection, thereby stopping the rest of the script from running.
Note that both severity level 20 or higher and the WITH LOG
option are necessary for it to work this way.
This even works with GO statements, eg.
print 'hi'
go
raiserror('Oh no a fatal error', 20, -1) with log
go
print 'ho'
Will give you the output:
hi
Msg 2745, Level 16, State 2, Line 1
Process ID 51 has raised user error 50000, severity 20. SQL Server is terminating this process.
Msg 50000, Level 20, State 1, Line 1
Oh no a fatal error
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
Notice that 'ho' is not printed.
CAVEATS:
The noexec method
Another method that works with GO statements is set noexec on
. This causes the rest of the script to be skipped over. It does not terminate the connection, but you need to turn noexec
off again before any commands will execute.
Example:
print 'hi'
go
print 'Fatal error, script will not continue!'
set noexec on
print 'ho'
go
-- last line of the script
set noexec off -- Turn execution back on; only needed in SSMS, so as to be able
-- to run this script again in the same session.
I made an online tool called Unclosed Tag Finder which will do what you need.
Paste in your HTML, and it will give you output like "Closing tag on line 188 does not match open tag on line 62."
Update: The new location of the Unclosed Tag Finder is https://jonaquino.blogspot.com/2013/05/unclosed-tag-finder.html
It happened in my case, because the name of the table being referenced in the constraint declaration wasn't correct (I forgot the upper case in the table name):
ALTER TABLE `Window` ADD CONSTRAINT `Windows_ibfk_1` FOREIGN KEY (`WallId`) REFERENCES `Wall` (`id`) ON DELETE CASCADE ON UPDATE CASCADE;
you can use
date -d "30 days ago" +"%d/%m/%Y"
to get the date from 30 days ago, similarly you can replace 30 with x amount of days
One option would be
const styleElement = getComputedStyle(document.getElementById("myDiv"));
console.log(styleElement.height);
On the Linux system you can do following (Should be similar for other OS)
Check if mysql process is running:
sudo service mysql status
If runnning then stop the process: (Make sure you close all mysql tool)
sudo service mysql stop
If you have issue stopping then do following
Search for process: ps aux | grep mysqld
Kill the process: kill -9 process_id
Now start mysql in safe mode with skip grant
sudo mysqld_safe --skip-grant-tables &
You could pass the messages as explicit URL parameter (appropriately encoded), or store the messages into session
(cookie) variable before redirecting and then get the variable before rendering the template. For example:
from flask import session, url_for
def do_baz():
messages = json.dumps({"main":"Condition failed on page baz"})
session['messages'] = messages
return redirect(url_for('.do_foo', messages=messages))
@app.route('/foo')
def do_foo():
messages = request.args['messages'] # counterpart for url_for()
messages = session['messages'] # counterpart for session
return render_template("foo.html", messages=json.loads(messages))
(encoding the session variable might not be necessary, flask may be handling it for you, but can't recall the details)
Or you could probably just use Flask Message Flashing if you just need to show simple messages.
The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).
If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:
Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.
You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).
As an aside, the login properties for sa
would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.
I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM
account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):
And some other resources:
select t1.*, sq.*
from table1 t1,
(select a,b,c from table2 ...) sq
where ...
Also do note when specifying DATETIME
as DATETIME(3)
or like on MySQL 5.7.x, you also have to add the same value for CURRENT_TIMESTAMP(3)
. If not it will keep throwing 'Invalid default value'.
If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".
Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".
substring(from: index) Converted to [index...]
Check the sample
let text = "1234567890"
let index = text.index(text.startIndex, offsetBy: 3)
text.substring(from: index) // "4567890" [Swift 3]
String(text[index...]) // "4567890" [Swift 4]
Use the filter_var()
function to validate whether a string is URL or not:
var_dump(filter_var('example.com', FILTER_VALIDATE_URL));
It is bad practice to use regular expressions when not necessary.
EDIT: Be careful, this solution is not unicode-safe and not XSS-safe. If you need a complex validation, maybe it's better to look somewhere else.
First of all go to the /home directorty then open invisible shell script with some text editor, ~/.bash_profile (macOS) or ~/.bashrc (linux)
go to the bottom, you would see something like this,
export LD_LIBRARY_PATH = /usr/local/lib
change this like that( remove blank point around the =
),
export LD_LIBRARY_PATH=/usr/local/lib
it should be useful.
You could do this:
var timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector("someSelector"), userInfo: nil, repeats: false)
func someSelector() {
// Something after a delay
}
let timer = Timer.scheduledTimer(timeInterval: 0.1, target: self, selector: #selector(someSelector), userInfo: nil, repeats: false)
func someSelector() {
// Something after a delay
}
I faced the same problem, I was ok to get its own dialog box with my message, but the problem I faced was : 1) It was giving message on all navigations I want it only for close click. 2) with my own confirmation message if user selects cancel it still shows the browser's default dialog box.
Following is the solutions code I found, which I wrote on my Master page.
function closeMe(evt) {
if (typeof evt == 'undefined') {
evt = window.event; }
if (evt && evt.clientX >= (window.event.screenX - 150) &&
evt.clientY >= -150 && evt.clientY <= 0) {
return "Do you want to log out of your current session?";
}
}
window.onbeforeunload = closeMe;
You need to make sure that the files on the device mounted by fuse will not have the same paths and file names as files which already existing in the nonempty mountpoint. Otherwise this would lead to confusion. If you are sure, pass -o nonempty
to the mount command.
You can try what is happening using the following commands.. (Linux rocks!) .. without destroying anything..
// create 10 MB file
dd if=/dev/zero of=partition bs=1024 count=10240
// create loopdevice from that file
sudo losetup /dev/loop0 ./partition
// create filesystem on it
sudo e2mkfs.ext3 /dev/loop0
// mount the partition to temporary folder and create a file
mkdir test
sudo mount -o loop /dev/loop0 test
echo "bar" | sudo tee test/foo
# unmount the device
sudo umount /dev/loop0
# create the file again
echo "bar2" > test/foo
# now mount the device (having file with same name on it)
# and see what happens
sudo mount -o loop /dev/loop0 test
I know it's an old question, but it's interesting. The example isn't the best. I think it would be much clearer if you showed a usage case:
string DoSomething<T>() where T:ISomeFunction { if (T.someFunction()) ... }
Merely being able to have static methods implement an interface would not achieve what you want; what would be needed would be to have static members as part of an interface. I can certainly imagine many usage cases for that, especially when it comes to being able to create things. Two approaches I could offer which might be helpful:
None of these approaches is really appealing. On the other hand, I would expect that if the mechanisms existed in CLR to provide this sort of functionality cleanly, .net would allow one to specify parameterized "new" constraints (since knowing if a class has a constructor with a particular signature would seem to be comparable in difficulty to knowing if it has a static method with a particular signature).
sed -i 's/[[:blank:]]\{1,\}$//' YourFile
[:blank:] is for space, tab mainly and {1,} to exclude 'no space at the end' of the substitution process (no big significant impact if line are short and file are small)
How about this? Just give it a thought-
import java.util.ArrayList;
class Solution
{
public static void main (String[] args){
ArrayList<String> List_Of_Array = new ArrayList<String>();
List_Of_Array.add("A");
List_Of_Array.add("B");
List_Of_Array.add("C");
List_Of_Array.add("D");
List_Of_Array.add("E");
List_Of_Array.add("F");
List_Of_Array.add("G");
List_Of_Array.add("H");
int i[] = {1,3,5};
for (int j = 0; j < i.length; j++) {
List_Of_Array.remove(i[j]-j);
}
System.out.println(List_Of_Array);
}
}
And the output was-
[A, C, E, G, H]
I recommend two steps to address the bloated SDK problem.
First, I removed all but two versions of Android:
The current version, e.g. 6.0 Marshmallow as of this writing. This version is to test and develop to the latest and greatest that the current Nexus handsets are running plus a couple of other brands.
An older version, e.g. 4.04 Ice Cream Sandwich. This is to provide compatibility for the vast majority of handsets. You lose some functionality of the newer versions, but you gain a lowest common denominator of compatibility.
Second, I removed the emulators, and kept only the above two. I told it not to store the complete system state to disk, which it does indeed warn you will take up a lot of space, though it does make start-up faster. Just start up the emulator before you go make your coffee in the morning :)
If that's too much space, remove the emulators completely. Pick up a couple of older handsets off Ebay that will provide you with all the test platforms you need. They don't even have to be completely functional -- many apps don't need a SIM and cellular connectivity, for example.
My Android environment was taking up 32 gigs on my 128-gig Macbook Air. Couldn't keep doing this. Some day they'll make terabyte Macbook Airs but until then, got to slim down.
The root (mathematical) reason is that when you are dealing with integers, they are countably infinite.
Which means, even though there are an infinite amount of them, we could "count out" all of the items in the sequence, without skipping any. That means if we want to get the item in the 610000000000000
th position in the list, we can figure it out via a formula.
However, real numbers are uncountably infinite. You can't say "give me the real number at position 610000000000000
" and get back an answer. The reason is because, even between 0
and 1
, there are an infinite number of values, when you are considering floating-point values. The same holds true for any two floating point numbers.
More info:
http://en.wikipedia.org/wiki/Countable_set
http://en.wikipedia.org/wiki/Uncountable_set
Update: My apologies, I appear to have misinterpreted the question. My response is about why we cannot represent every real value, I hadn't realized that floating point was automatically classified as rational.

firstarray
and secondarray
are converted to a pointer to int, when passed to printarray()
.
printarray(int arg[], ...)
is equivalent to printarray(int *arg, ...)
However, this is not specific to C++. C has the same rules for passing array names to a function.
Looks like you are running afoul of this rule for updating views from Books Online: "INSERT statements must specify values for any columns in the underlying table that do not allow null values and have no DEFAULT definitions."
You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:
import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values
... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.
If you just want to execute the shell command in your c program, you could use,
#include <stdlib.h>
int system(const char *command);
In your case,
system("pwd");
The issue is that there isn't an executable file called "pwd" and I'm unable to execute "echo $PWD", since echo is also a built-in command with no executable to be found.
What do you mean by this? You should be able to find the mentioned packages in /bin/
sudo find / -executable -name pwd
sudo find / -executable -name echo
All of my tasks (which need to be scheduled) for a website are kept within the website and called from a special page. I then wrote a simple Windows service which calls this page every so often. Once the page runs it returns a value. If I know there is more work to be done, I run the page again, right away, otherwise I run it in a little while. This has worked really well for me and keeps all my task logic with the web code. Before writing the simple Windows service, I used Windows scheduler to call the page every x minutes.
Another convenient way to run this is to use a monitoring service like Pingdom. Point their http check to the page which runs your service code. Have the page return results which then can be used to trigger Pingdom to send alert messages when something isn't right.
The currently accepted answer works, but will install an outdated version of Mongo.
The Mongo documentation states that: MongoDB only provides packages for Ubuntu 12.04 LTS (Precise Pangolin) and 14.04 LTS (Trusty Tahr). However, These packages may work with other Ubuntu releases.
So, to get the lastest stable Mongo (3.0
), use this (the different step is the second one):
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list
apt-get update
apt-get install mongodb-org
Hope this helps.
I would like to add that as a previous step, you must check your GNU/Linux Distro Release, which will construct the Repo list url. For me, as I am using this:
DISTRIB_CODENAME=rafaela
DISTRIB_DESCRIPTION="Linux Mint 17.2 Rafaela"
NAME="Ubuntu"
VERSION="14.04.2 LTS, Trusty Tahr"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 14.04.2 LTS"
The original 2nd step:
"Create a list file for MongoDB": "echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list"
Didn't work as intended because it generated an incorrect Repo url. Basically, it put the distribution codename "rafaela" within the url repo which doesn't exist. You can check the Repo url at your package manager under Software Sources, Additional Repositories.
What I did was to browse the site:
http://repo.mongodb.org/apt/ubuntu/dists/
And I found out that for Ubuntu, "trusty" and "precise" are the only web folders available, not "rafaela".
Solution: Open as root the file 'mongodb-org-3.1.list' or 'mongodb.list' and replace "rafaela" or your release version for the corresponding version (for me it was: "trusty"), save the changes and continue with next steps. Also, your package manager can let you change easily the repo url as well.
Hope it works for you.! ---
If using the 'typetable reference' approach (from @Carl G) and you're using multiple type tables you might want to consider this way :
export default class AppComponent {
// Store a reference to the enums (must be public for --AOT to work)
public TT = {
CellType: CellType,
CatType: CatType,
DogType: DogType
};
...
dog = DogType.GoldenRetriever;
Then access in your html file with
{{ TT.DogType[dog] }} => "GoldenRetriever"
I favor this approach as it makes it clear you're referring to a typetable, and also avoids unnecessary pollution of your component file.
You can also put a global TT
somewhere and add enums to it as needed (if you want this you may as well make a service as shown by @VincentSels answer). If you have many many typetables this may become cumbersome.
Also you always rename them in your declaration to get a shorter name.
You could use RAISE_APPLICATION_ERROR like this:
DECLARE
ex_custom EXCEPTION;
BEGIN
RAISE ex_custom;
EXCEPTION
WHEN ex_custom THEN
RAISE_APPLICATION_ERROR(-20001,'My exception was raised');
END;
/
That will raise an exception that looks like:
ORA-20001: My exception was raised
The error number can be anything between -20001 and -20999.
With PowerShell 2.0 (Windows 7 preinstalled) you can use:
(New-Object Net.WebClient).DownloadFile('http://www.example.com/package.zip', 'package.zip')
Starting with PowerShell 3.0 (Windows 8 preinstalled) you can use Invoke-WebRequest
:
Invoke-WebRequest http://www.example.com/package.zip -OutFile package.zip
From a batch file they are called:
powershell -Command "(New-Object Net.WebClient).DownloadFile('http://www.example.com/package.zip', 'package.zip')"
powershell -Command "Invoke-WebRequest http://www.example.com/package.zip -OutFile package.zip"
(PowerShell 2.0 is available for installation on XP, 3.0 for Windows 7)
To only modify the title's font (and not the font of the axis) I used this:
import matplotlib.pyplot as plt
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.set_title('My Title', fontdict={'fontsize': 8, 'fontweight': 'medium'})
The fontdict accepts all kwargs from matplotlib.text.Text.
If you are using the ADT version 22, you need to check the android dependencies and android private libraries in the order&Export tab in the project build path

Ya, the problem was double setter.
This is a helpful video and blog post about removing node from your computer OS. It is a different method of removal based on how you installed node in the first place (brew vs. binary file downloaded from https://nodejs.org/en/
if you installed node with Homebrew then brew uninstall node will work. Verify that with running a node -v
command in your terminal.
Otherwise and if you have installed the binary file from nodeJS's websitethen you have to run this command in your terminal: sudo rm -rf /usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man/*/node.*}
. Again, verify that with running a node -v command.
In both cases, successful removal of node should result in bash not recognizing what node is if it is completely removed
When using this approach you have to make sure that none of your values contains something that would be illegal XML – user1151923
I always use the XML method. Make sure you use VALID XML. I have two functions to convert between valid XML and Text. (I tend to strip out the carriage returns as I don't usually need them.
CREATE FUNCTION dbo.udf_ConvertTextToXML (@Text varchar(MAX))
RETURNS varchar(MAX)
AS
BEGIN
SET @Text = REPLACE(@Text,CHAR(10),'')
SET @Text = REPLACE(@Text,CHAR(13),'')
SET @Text = REPLACE(@Text,'<','<')
SET @Text = REPLACE(@Text,'&','&')
SET @Text = REPLACE(@Text,'>','>')
SET @Text = REPLACE(@Text,'''',''')
SET @Text = REPLACE(@Text,'"','"')
RETURN @Text
END
CREATE FUNCTION dbo.udf_ConvertTextFromXML (@Text VARCHAR(MAX))
RETURNS VARCHAR(max)
AS
BEGIN
SET @Text = REPLACE(@Text,'<','<')
SET @Text = REPLACE(@Text,'&','&')
SET @Text = REPLACE(@Text,'>','>')
SET @Text = REPLACE(@Text,''','''')
SET @Text = REPLACE(@Text,'"','"')
RETURN @Text
END
Swift 3 with a Closure
A nice solution is using a closure in a custom UITableViewCell to callback to the viewController for an action.
In cell:
final class YourCustomCell: UITableViewCell {
var callbackClosure: (() -> Void)?
// Configure the cell here
func configure(object: Object, callbackClosure: (() -> Void)?) {
self.callbackClosure = callbackClosure
}
// MARK: - IBAction
extension YourCustomCell {
@IBAction fileprivate func actionPressed(_ sender: Any) {
guard let closure = callbackClosure else { return }
closure()
}
}
In View Controller: Tableview Delegate
extension YourViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
guard let cell: YourCustomCell = cell as? YourCustomCell else { return }
cell.configure(object: object, callbackClosure: { [weak self] in
self?.buttonAction()
})
}
}
fileprivate extension YourViewController {
func buttonAction() {
// do your actions here
}
}
You can combine the two functions; coerce to characters thence to numerics:
> fac <- factor(c("1","2","1","2"))
> as.numeric(as.character(fac))
[1] 1 2 1 2
To be specific, set the value to be the name of a constant of the enum type, e.g., "TYPE1" or "TYPE2" in your case, as shown below. And it will work:
<bean name="someName" class="my.pkg.classes">
<property name="type" value="TYPE1" />
</bean>
you can get all product information from following code
$product_id=6//Suppose
$_product=Mage::getModel('catalog/product')->load($product_id);
$product_data["id"]=$_product->getId();
$product_data["name"]=$_product->getName();
$product_data["short_description"]=$_product->getShortDescription();
$product_data["description"]=$_product->getDescription();
$product_data["price"]=$_product->getPrice();
$product_data["special price"]=$_product->getFinalPrice();
$product_data["image"]=$_product->getThumbnailUrl();
$product_data["model"]=$_product->getSku();
$product_data["color"]=$_product->getAttributeText('color'); //get cusom attribute value
$storeId = Mage::app()->getStore()->getId();
$summaryData = Mage::getModel('review/review_summary')->setStoreId($storeId) ->load($_product->getId());
$product_data["rating"]=($summaryData['rating_summary']*5)/100;
$product_data["shipping"]=Mage::getStoreConfig('carriers/flatrate/price');
if($_product->isSalable() ==1)
$product_data["in_stock"]=1;
else
$product_data["in_stock"]=0;
echo "<pre>";
print_r($product_data);
//echo "</pre>";
I've got a handy extension method that uses TryParse, as IsDefined is case-sensitive.
public static bool IsParsable<T>(this string value) where T : struct
{
return Enum.TryParse<T>(value, true, out _);
}
DECLARE @date DateTime
SET @date = GetDate()
SET @date = DateAdd(day, 1, @date)
SELECT @date
You just need to use these commands
sudo rm -rf /Library/Java/*
sudo rm -rf /Library/PreferencePanes/Java*
sudo rm -rf /Library/Internet\ Plug-Ins/Java*
Just FYI, got the error trying to apply row style....

Check if have not set a open_basedir in php.ini or .htaccess of domain what you use. That will jail you in directory of your domain and php will get only access to execute inside this directory.
This look like a duplicate of JSTL conditional check.
The error is having the &&
outside the expression. Instead use
<c:if test="${ISAJAX == 0 && ISDATE == 0}">
Use table-layout property and the "fixed" value on your table.
table {
table-layout: fixed;
width: 300px; /* your desired width */
}
After setting up the entire width of the table, you can now setup the width in % of the td's.
td:nth-child(1), td:nth-child(2) {
width: 15%;
}
You can learn more about in on this link: http://www.w3schools.com/cssref/pr_tab_table-layout.asp
MySQL will also report "Column count doesn't match value count at row 1" if you try to insert multiple rows without delimiting the row sets in the VALUES section with parentheses, like so:
INSERT INTO `receiving_table`
(id,
first_name,
last_name)
VALUES
(1002,'Charles','Babbage'),
(1003,'George', 'Boole'),
(1001,'Donald','Chamberlin'),
(1004,'Alan','Turing'),
(1005,'My','Widenius');
If this is for any general math expression and parenthetical expressions are allowed, it will be very difficult (perhaps impossible) to do this with regular expressions.
If the only replacements are the ones you showed, it's not that hard to do. First strip out *
's, then use capturing like Can Berk Güder showed to handle the ^
's.
I had a similar problem, I wanted to change the format, but I also wanted the flexibility of being able to change the format in the blade template engine too.
I, therefore, set my model up as the following:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
\Carbon\Carbon::setToStringFormat('d-m-Y');
class User extends Model
{
protected $dates = [
'from_date',
];
}
The setToStringFormat
will set all the dates to use this format for this model.
The advantage of this for me is that I could have the format that I wanted without the mutator, because with the mutator, the attribute is returned as a string meaning that in the blade template I would have to write something like this if I wanted to change the format in the template:
{{ date('Y', strtotime($user->from_date)) }}
Which isn't very clean.
Instead, the attribute is still returned as a Carbon instance, however it is first returned in the desired format.
That means that in the template I could write the following, cleaner, code:
{{ $user->from_date->format('Y') }}
In addition to being able to reformat the Carbon instance, I can also call various Carbon methods on the attribute in the template.
There is probably an oversight to this approach; I'm going to wager it is not a good idea to specify the string format at the top of the model in case it affects other scripts. From what I have seen so far, that has not happened. It has only changed the default Carbon for that model only.
In this instance, it might be a good set the Carbon format back to what it was originally at the bottom of the model script. This is a bodged idea, but it would work for each model to have its own format.
Contrary, if you are having the same format for each model then in your AppServiceProvider instead. That would just keep the code neater and easier to maintain.
What you can do is select everything into a new instance of Course, and afterwards convert them to a List.
var qry = from a in obj.tbCourses
select new Course() {
Course.Property = a.Property
...
};
qry.toList<Course>();
In later versions of CMake, one way to do it on each target is:
set_target_properties(MyTarget PROPERTIES COMPILE_FLAGS "-m32" LINK_FLAGS "-m32")
I don't know of a way to do it globally.
Run this query from PostgreSQL:
SELECT version();
Partly, because Go doesn't have generics (so you would need one set-type for every type, or fall back on reflection, which is rather inefficient).
Partly, because if all you need is "add/remove individual elements to a set" and "relatively space-efficient", you can get a fair bit of that simply by using a map[yourtype]bool
(and set the value to true
for any element in the set) or, for more space efficiency, you can use an empty struct as the value and use _, present = the_setoid[key]
to check for presence.
Here is what I came up with. I was having major problems with this and believe I am in MVC 6 now but this may be helpful to someone even myself in the future..
//The issue was that Reqest.Form Request.Querystring and Request not working in MVC the solution is to use Context.Request.Form and also making sure the form has been submitted otherwise null reference or context issue bug will show up.
if(Context.Request.ContentLength != null)
{
String StartDate = Context.Request.Form["StartMonth"].ToString();
String EndMonth = Context.Request.Form["EndMonth"].ToString();

With the introduction of (i|android|windows)phones, things have changed, and to get a correct and complete solution that works on any device is really time-consuming.
You can have a peek at https://realfavicongenerator.net/favicon_compatibility or http://caniuse.com/#search=favicon to get an idea on the best way to get something that works on any device.
You should have a look at http://realfavicongenerator.net/ to automate a large part of this work, and probably at https://github.com/audreyr/favicon-cheat-sheet to understand how it works (even if this latter resource hasn't been updated in a loooong time).

Bootstrap will add or remove a css "modal-open"
to the <body>
tag when we open or close a modal. So if you open multiple modal and then close arbitrary one, the modal-open css will be removed from the body tag.
But the scroll effect depend on the attribute "overflow-y: auto;"
defined in modal-open
You can use the row_number()

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
FROM PM_Ingrediants cross join
(select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
)
Finally, you can just make the sequence
column an auto-incrementing identity column. This saves the need to increment it each time:
create table PM_Ingrediants_Arrangement_Temp ( . . .
sequence int identity(1, 1) -- and might consider making this a primary key too
. . .
)
you can get filename by uri with simple way
fun get_filename_by_uri(uri : Uri) : String{
contentResolver.query(uri, null, null, null, null).use { cursor ->
cursor?.let {
val nameIndex = it.getColumnIndex(OpenableColumns.DISPLAY_NAME)
it.moveToFirst()
return it.getString(nameIndex)
}
}
return ""
}
and easy to read it by using
contentResolver.openInputStream(uri)
You have to escape each \
to be \\
:
var ttt = "aa ///\\\\\\";
Updated: I think this question is not about the escape character in string at all. The asker doesn't seem to explain the problem correctly.
because you had to show a message to user that user can't give a name which has (\) character.
I think the scenario is like:
var user_input_name = document.getElementById('the_name').value;
Then the asker wants to check if user_input_name
contains any [\
]. If so, then alert the user.
If user enters [aa ///\
] in HTML input box, then if you alert(user_input_name)
, you will see [aaa ///\
]. You don't need to escape, i.e. replace [\
] to be [\\
] in JavaScript code. When you do escaping, that is because you are trying to make of a string which contain special characters in JavaScript source code. If you don't do it, it won't be parsed correct. Since you already get a string, you don't need to pass it into an escaping function. If you do so, I am guessing you are generating another JavaScript code from a JavaScript code, but it's not the case here.
I am guessing asker wants to simulate the input, so we can understand the problem. Unfortunately, asker doesn't understand JavaScript well. Therefore, a syntax error code being supplied to us:
var ttt = "aa ///\";
Hence, we assume the asker having problem with escaping.
If you want to simulate, you code must be valid at first place.
var ttt = "aa ///\\"; // <- This is correct
// var ttt = "aa ///\"; // <- This is not.
alert(ttt); // You will see [aa ///\] in dialog, which is what you expect, right?
Now, you only need to do is
var user_input_name = document.getElementById('the_name').value;
if (user_input_name.indexOf("\\") >= 0) { // There is a [\] in the string
alert("\\ is not allowed to be used!"); // User reads [\ is not allowed to be used]
do_something_else();
}
Edit: I used []
to quote text to be shown, so it would be less confused than using ""
.
There is no way to get the logs for installing problems.
You can use the str.split
method: string.split('__')
>>> "MATCHES__STRING".split("__")
['MATCHES', 'STRING']
I had a .NET 4.0, ASP.NET MVC 2.0, Entity Framework 4.0 web application developed in Visual Studio 2010. I had the same problem, that it worked on one Windows Server 2008 R2 server but not on another Windows Server 2008 R2 server, even though the versions of .NET and ASP.NET MVC were the same, throwing this same error as yours.
I went to follow miko's suggestion, so I installed Windows SDK v7.1 (x64) on the failing server, so I could run !dumpheap.
Well, it turns out that installing Windows SDK v7.1 (x64) resolved the issue. Whatever dependency was missing must have been included in the SDK. It can be downloaded from Microsoft Windows SDK for Windows 7 and .NET Framework 4.
In my case, inside a Spring4 Application, i had to use a classic Abstract Factory Pattern(for which i took the idea from - http://java-design-patterns.com/patterns/abstract-factory/) to create instances each and every time there was a operation to be done.So my code was to be designed like:
public abstract class EO {
@Autowired
protected SmsNotificationService smsNotificationService;
@Autowired
protected SendEmailService sendEmailService;
...
protected abstract void executeOperation(GenericMessage gMessage);
}
public final class OperationsExecutor {
public enum OperationsType {
ENROLL, CAMPAIGN
}
private OperationsExecutor() {
}
public static Object delegateOperation(OperationsType type, Object obj)
{
switch(type) {
case ENROLL:
if (obj == null) {
return new EnrollOperation();
}
return EnrollOperation.validateRequestParams(obj);
case CAMPAIGN:
if (obj == null) {
return new CampaignOperation();
}
return CampaignOperation.validateRequestParams(obj);
default:
throw new IllegalArgumentException("OperationsType not supported.");
}
}
}
@Configurable(dependencyCheck = true)
public class CampaignOperation extends EO {
@Override
public void executeOperation(GenericMessage genericMessage) {
LOGGER.info("This is CAMPAIGN Operation: " + genericMessage);
}
}
Initially to inject the dependencies in the abstract class I tried all stereotype annotations like @Component, @Service etc but even though Spring context file had ComponentScanning for the entire package, but somehow while creating instances of Subclasses like CampaignOperation, the Super Abstract class EO was having null for its properties as spring was unable to recognize and inject its dependencies.After much trial and error I used this **@Configurable(dependencyCheck = true)**
annotation and finally Spring was able to inject the dependencies and I was able to use the properties in the subclass without cluttering them with too many properties.
<context:annotation-config />
<context:component-scan base-package="com.xyz" />
I also tried these other references to find a solution:
Please try using **@Configurable(dependencyCheck = true)**
and update this post, I might try helping you if you face any problems.
You need a section in your file:
[My Section]
path1 = D:\test1\first
path2 = D:\test2\second
path3 = D:\test2\third
Then, read the properties:
import ConfigParser
config = ConfigParser.ConfigParser()
config.readfp(open(r'abc.txt'))
path1 = config.get('My Section', 'path1')
path2 = config.get('My Section', 'path2')
path3 = config.get('My Section', 'path3')
this setting worked for me:
On my Linux machine :
git config --system --get https.proxy (returns nothing)
git config --global --get https.proxy (returns nothing)
git config --system --get http.proxy (returns nothing)
git config --global --get http.proxy (returns nothing)
I found out my https_proxy and http_proxy are set, so I just unset them.
unset https_proxy
unset http_proxy
On my Windows machine :
set https_proxy=""
set http_proxy=""
Optionally use setx to set environment variables permanently on Windows and set system environment using "/m"
setx https_proxy=""
setx http_proxy=""
In my case, after waiting so much for it to finish I had no patience and simply closed management studio. Before exiting, it showed the success message, db is offline. The files were available to rename.
\n
is an escape sequence, denoted by the backslash. A normal forward slash, such as /n
will not do the job. In your code you are using /n
instead of \n
.
Here is another approach of writing Notification Service inside ASP.Net REST API.
public async Task<bool> NotifyAsync(string to, string title, string body)
{
try
{
// Get the server key from FCM console
var serverKey = string.Format("key={0}", "Your server key - use app config");
// Get the sender id from FCM console
var senderId = string.Format("id={0}", "Your sender id - use app config");
var data = new
{
to, // Recipient device token
notification = new { title, body }
};
// Using Newtonsoft.Json
var jsonBody = JsonConvert.SerializeObject(data);
using (var httpRequest = new HttpRequestMessage(HttpMethod.Post, "https://fcm.googleapis.com/fcm/send"))
{
httpRequest.Headers.TryAddWithoutValidation("Authorization", serverKey);
httpRequest.Headers.TryAddWithoutValidation("Sender", senderId);
httpRequest.Content = new StringContent(jsonBody, Encoding.UTF8, "application/json");
using (var httpClient = new HttpClient())
{
var result = await httpClient.SendAsync(httpRequest);
if (result.IsSuccessStatusCode)
{
return true;
}
else
{
// Use result.StatusCode to handle failure
// Your custom error handler here
_logger.LogError($"Error sending notification. Status Code: {result.StatusCode}");
}
}
}
}
catch (Exception ex)
{
_logger.LogError($"Exception thrown in Notify Service: {ex}");
}
return false;
}

With Pillow, you can also draw on an image using the ImageDraw module. You can draw lines, points, ellipses, rectangles, arcs, bitmaps, chords, pieslices, polygons, shapes and text.
from PIL import Image, ImageDraw
blank_image = Image.new('RGBA', (400, 300), 'white')
img_draw = ImageDraw.Draw(blank_image)
img_draw.rectangle((70, 50, 270, 200), outline='red', fill='blue')
img_draw.text((70, 250), 'Hello World', fill='green')
blank_image.save('drawn_image.jpg')
we create an Image object with the new() method. This returns an Image object with no loaded image. We then add a rectangle and some text to the image before saving it.
You can run with this code
tsc .\src\index.ts --experimentalDecorators "true" --emitDecoratorMetadata "true"
teststr=$'test1\n'
teststr+=$'test2\n'
echo "$teststr"
The way of dknaack does not work for me, I found this solution as well:
@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList,
"Select chapter", new { @onchange = "location = this.value;" })
where
@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)
In the controller you can add:
DbModel db = new DbModel(); //entity model of Entity Framework
ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");
If you want something quick and dirty, you can just add a Thread.sleep() call within your while loop. If the database library is something you can't change, then there is really no other easy solution. Polling the database until is ready with a wait period won't kill the performance.
while (!dbthread.isReady()) {
Thread.sleep(250);
}
Hardly something that you could call elegant code, but gets the work done.
In case you can modify the database code, then using a mutex as proposed in other answers is better.
I recently needed to do this as well... here's how I got to it:
$_product->getMediaGalleryImages()->getItemByColumnValue('label', 'LABEL_NAME')->getUrl();
Hope that helps you!
You use separator when you are building a file path. So in unix the separator is /
. So if you wanted to build the unix path /var/temp
you would do it like this:
String path = File.separator + "var"+ File.separator + "temp"
You use the pathSeparator
when you are dealing with a list of files like in a classpath. For example, if your app took a list of jars as argument the standard way to format that list on unix is: /path/to/jar1.jar:/path/to/jar2.jar:/path/to/jar3.jar
So given a list of files you would do something like this:
String listOfFiles = ...
String[] filePaths = listOfFiles.split(File.pathSeparator);
If you're using jQuery, it's as simple as this:
$('#mySelect').change(function()
{
$('#myForm').submit();
});
There are a lot of answers, but none is stressing that calling another lambda function is not recommended solution for synchronous calls and the one that you should be using is really Step Functions
Reasons why it is not recommended solution:
You can also use it for quite complex logic, such as parallel steps and catch failures. Every execution is also being logged out which makes debugging much simpler.
You'll get this error when the certificate is newer than your Java version. Using a newer Java version will solve this.
For me it was different, I used a button theme
<style name="ButtonLight_pink" parent="android:Widget.Button">
<item name="android:background">@drawable/light_pink_btn_default_holo_light</item>
<item name="android:minHeight">48dip</item>
<item name="android:minWidth">64dip</item>
<item name="android:textColor">@color/tab_background_light_pink</item>
</style>
and because android:textColor
was white there… I didn't see any button text (Dialog buttons are basically buttons too).
There we go, changed it, fixed it.
For your Q2, there are already answers to your question. For your Q1, and more generally when you know that the key's filtering should give a unique value, there's no need to use Streams at all.
Just use get
or getOrDefault
, i.e:
List<String> list1 = id1.getOrDefault(1, Collections.emptyList());

Put these inside a .hta

The following code the easiest way:
<h:outputLabel value="value = 10" rendered="#{row == 10}" />
<h:outputLabel value="value = 15" rendered="#{row == 15}" />
<h:outputLabel value="value xyz" rendered="#{row != 15 and row != 10}" />

It's simple Use following pseudo code
from pylab import imread,subplot,imshow,show
import matplotlib.pyplot as plt
image = imread('...') // choose image location
plt.imshow(image)
plt.show()
// this will show you the image on console.
I use prop attribute for unchecked
the checkbox
when errors occur.
You don't need to use remove property for unchecked your checkbox.
$('input#IDName').prop('checked', false);
It is working fine for me. Hope it will work for you also.
Simply use CSS padding rules with table data:
td {
padding: 20px;
}
And for border spacing:
table {
border-spacing: 1px;
border-collapse: collapse;
}
However, it can create problems in older version of browsers like Internet Explorer because of the diff implementation of the box model.
DBMS is the software program that is used to manage all the database that are stored on the network or system hard disk. whereas RDBMS is the database system in which the relationship among different tables are maintained.
In Scala, a List inherits from Seq, but implements Product; here is the proper definition of List :
sealed abstract class List[+A] extends AbstractSeq[A] with Product with ...
[Note: the actual definition is a tad bit more complex, in order to fit in with and make use of Scala's very powerful collection framework.]
This is because you're using getActivity()
inside an inner class. Try using:
SherlockFragmentActivity.this.getActivity()
instead, though there's really no need for the getActivity()
part. In your case,
SherlockFragmentActivity .this
should suffice.
Just use DROP TABLE IF EXISTS
:
DROP TABLE IF EXISTS `foo`;
CREATE TABLE `foo` ( ... );
Try searching the MySQL documentation first if you have any other problems.
It's also possible to use sleep command in while's condition. Making one-liner looking more clean imho.
while sleep 2; do echo thinking; done
Do you mean elif
?
Android 6.0 (API Level 23) release removes support for the Apache HTTP client. Hence you can not use this library directly in API 23. But there is a way to use it. Add useLibrary ‘org.apache.http.legacy’ in your build.gradle file as below-
android {
useLibrary 'org.apache.http.legacy'
}
If this does not work you may apply the following hack-
– Copy org.apache.http.legacy.jar which is in /platforms/android-23/optional path of your Android SDK directory to your project’s app/libs folder.
– Now Add compile files(‘libs/org.apache.http.legacy.jar’) inside dependencies{} section of build.gradle file.
By default forever places all of the files it needs into /$HOME/.forever. If you would like to change that location just set the FOREVER_ROOT environment variable when you are running forever:
FOREVER_ROOT=/etc/forever forever start index.js
Examining the pros and cons
In favor of single quotes
elem.innerHTML = '<a href="' + url + '">Hello</a>';
_x000D_
elem.innerHTML = "<a href='" + url + "'>Hello</a>";
_x000D_
Furthermore, inline HTML is normally an anti-pattern. Prefer templates.
myJson = '{ "hello world": true }';
_x000D_
Again, you shouldn’t have to construct JSON this way. JSON.stringify() is often enough. If not, use templates.
In favor of double quotes
In favor of both
There is no difference between the two in JavaScript. Therefore, you can use whatever is convenient at the moment. For example, the following string literals all produce the same string:
"He said: \"Let's go!\""_x000D_
'He said: "Let\'s go!"'_x000D_
"He said: \"Let\'s go!\""_x000D_
'He said: \"Let\'s go!\"'
_x000D_
Single quotes for internal strings and double for external. That allows you to distinguish internal constants from strings that are to be displayed to the user (or written to disk etc.). Obviously, you should avoid putting the latter in your code, but that can’t always be done.
With the openJDK 11 you can use the internal validation to check if the String is null or just white spaces
import jdk.internal.joptsimple.internal.Strings;
...
String targetString;
if (Strings.isNullOrEmpty(tragetString)) {}
If you're using SASS you could also use this mixin:
@mixin headings {
h1, h2, h3,
h4, h5, h6 {
@content;
}
}
Use it like so:
@include headings {
font: 32px/42px trajan-pro-1, trajan-pro-2;
}
Edit: My personal favourite way of doing this by optionally extending a placeholder selector on each of the heading elements.
h1, h2, h3,
h4, h5, h6 {
@extend %headings !optional;
}
Then I can target all headings like I would target any single class, for example:
.element > %headings {
color: red;
}
You could try box-reflect
box-reflect: 20px right;

Bootstrap 3
Yes, it's possible. This "off-canvas" example should help to get you started.
https://codeply.com/p/esYgHWB2zJ
Basically you need to wrap the layout in an outer div, and use media queries to toggle the layout on smaller screens.
/* collapsed sidebar styles */
@media screen and (max-width: 767px) {
.row-offcanvas {
position: relative;
-webkit-transition: all 0.25s ease-out;
-moz-transition: all 0.25s ease-out;
transition: all 0.25s ease-out;
}
.row-offcanvas-right
.sidebar-offcanvas {
right: -41.6%;
}
.row-offcanvas-left
.sidebar-offcanvas {
left: -41.6%;
}
.row-offcanvas-right.active {
right: 41.6%;
}
.row-offcanvas-left.active {
left: 41.6%;
}
.sidebar-offcanvas {
position: absolute;
top: 0;
width: 41.6%;
}
#sidebar {
padding-top:0;
}
}
Also, there are several more Bootstrap sidebar examples here
Bootstrap 4
For those using Docker or Docker Compose, I experienced this error because I didn't set my MySQL image version. Docker will automatically attempt to get the latest version which is 8.
I set MySQL to 5.7 and rebuilt the image and it worked as normal:
version: '2'
services:
db:
image: mysql:5.7
On debian 7.5 I got the same error. I realized the /tmp
folder owner and permissions were off. As another answer suggested I did as follows (must be root):
chown root:root /tmp && chmod 1777 /tmp
I did not even have to restart mysql daemon.
I was facing the same error:
session not created: This version of ChromeDriver only supports Chrome version 75
...
Driver info: driver.version: ChromeDriver
We are running the tests from a computer that has no real UI, so I had to work via a command line (CLI).
I started by detecting the current version of Chrome that was installed on the Linux computer:
$> google-chrome --version
And got this response:
Google Chrome 74.0.3729.169
So then I updated the Chrome version like that:
$> sudo apt-get install google-chrome-stable
And after checking again the version I got this:
Google Chrome 75.0.3770.100
Then the Selenium tests were able to run smoothly.
subprocess.Popen
takes a cwd
argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'
), or use r'd:\test\local'
so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t
part will be translated to a tab.
So, your new line should look like:
subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')
To use your Python script path as cwd, import os
and define cwd using this:
os.path.dirname(os.path.realpath(__file__))
One thing that I found out (the hard way), is that you should have
$('#selectField').change(function(){
// some content ...
});
defined BEFORE you are using
$('#selectField').val(10).trigger('change');
or
$('#selectField').val(10).change();
Try this statement:
exit 1
Replace 1
with appropriate error codes. See also Exit Codes With Special Meanings.
This is an old question, but I'd say none of the answers really fits the OP's question. All he wanted/needed to do is this:
char c = std::fgetc(fp);
std::strcpy(buffer, &c);
The relevant aspect here is the fact, that the second argument of strcpy()
doesn't need to be a char array / c-string. In fact, none of the arguments is a char or char array at all. They are both char pointers:
strcpy(char* dest, const char* src);
dest :
A non-const char pointersrc :
A const char pointer\0
within its remaining elements (starting with src
), to mark the end of the c-string that should be copied.
As Patrick said, appending the LISTs from each SELECT would be a good idea but remember that it acts like UNION ALL. To avoid this side effect, just control if the object is already added in final collection or not. If no, then add it.
Something else that you should care about is that if you have any JOIN in each SELECT, the result would be a list of object array(List<Objetc[]>
) so you have to iterate over it to only keep the object that you need.
Hope it works.
In case you were looking to transform your column number into a letter:
Function ConvertToLetter(iCol As Integer) As String
Dim iAlpha As Integer
Dim iRemainder As Integer
iAlpha = Int(iCol / 27)
iRemainder = iCol - (iAlpha * 26)
If iAlpha > 0 Then
ConvertToLetter = Chr(iAlpha + 64)
End If
If iRemainder > 0 Then
ConvertToLetter = ConvertToLetter & Chr(iRemainder + 64)
End If
End Function
This way you could do something like this:
Function selectColumnRange(colNum As Integer, targetWorksheet As Worksheet)
Dim colLetter As String
Dim testRange As Range
colLetter = ConvertToLetter(colNum)
testRange = targetWorksheet.Range(colLetter & ":" & colLetter).Select
End Function
That example function would select the entire column ( i.e. Range("A:A").Select)
Html Code:-
<a href="#" id="playerID">Play</a>
<iframe src="https://www.youtube.com/embed/videoID" class="embed-responsive-item" data-play="0" id="VdoID" ></iframe>
Jquery Code:-
$('#playerID').click(function(){
var videoURL = $('#VdoID').attr('src'),
dataplay = $('#VdoID').attr('data-play');
//for check autoplay
//if not set autoplay=1
if(dataplay == 0 ){
$('#VdoID').attr('src',videoURL+'?autoplay=1');
$('#VdoID').attr('data-play',1);
}
else{
var videoURL = $('#VdoID').attr('src');
videoURL = videoURL.replace("?autoplay=1", "");
$('#VdoID').prop('src','');
$('#VdoID').prop('src',videoURL);
$('#VdoID').attr('data-play',0);
}
});
Thats It!
You need to set the error mode attribute PDO::ATTR_ERRMODE to PDO::ERRMODE_EXCEPTION.
And since you expect the exception to be thrown by the prepare() method you should disable the PDO::ATTR_EMULATE_PREPARES* feature. Otherwise the MySQL server doesn't "see" the statement until it's executed.
<?php
try {
$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->prepare('INSERT INTO DoesNotExist (x) VALUES (?)');
}
catch(Exception $e) {
echo 'Exception -> ';
var_dump($e->getMessage());
}
prints (in my case)
Exception -> string(91) "SQLSTATE[42S02]: Base table or view not found:
1146 Table 'test.doesnotexist' doesn't exist"
see http://wezfurlong.org/blog/2006/apr/using-pdo-mysql/
EMULATE_PREPARES=true seems to be the default setting for the pdo_mysql driver right now.
The query cache thing has been fixed/change since then and with the mysqlnd driver I hadn't problems with EMULATE_PREPARES=false (though I'm only a php hobbyist, don't take my word on it...)
*) and then there's PDO::MYSQL_ATTR_DIRECT_QUERY - I must admit that I don't understand the interaction of those two attributes (yet?), so I set them both, like
$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly', array(
PDO::ATTR_EMULATE_PREPARES=>false,
PDO::MYSQL_ATTR_DIRECT_QUERY=>false,
PDO::ATTR_ERRMODE=>PDO::ERRMODE_EXCEPTION
));

The fontawesome.css file does not include the font reference.
In swift 4 & Xcode 9.2 , you can detect if a device is iPhone/iPad by below ways.
if (UIDevice.current.userInterfaceIdiom == .pad){
print("iPad")
}
else{
print("iPhone")
}
Another Way
let deviceName = UIDevice.current.model
print(deviceName);
if deviceName == "iPhone"{
print("iPhone")
}
else{
print("iPad")
}
For my use (node names with xy positions) I found @user4179775's answer to the most helpful / intuitive:
import pandas as pd
df = pd.read_csv('glycolysis_nodes_xy.tsv', sep='\t')
df.head()
nodes x y
0 c00033 146 958
1 c00031 601 195
...
xy_dict_list=dict([(i,[a,b]) for i, a,b in zip(df.nodes, df.x,df.y)])
xy_dict_list
{'c00022': [483, 868],
'c00024': [146, 868],
... }
xy_dict_tuples=dict([(i,(a,b)) for i, a,b in zip(df.nodes, df.x,df.y)])
xy_dict_tuples
{'c00022': (483, 868),
'c00024': (146, 868),
... }
Addendum
I later returned to this issue, for other, but related, work. Here is an approach that more closely mirrors the [excellent] accepted answer.
node_df = pd.read_csv('node_prop-glycolysis_tca-from_pg.tsv', sep='\t')
node_df.head()
node kegg_id kegg_cid name wt vis
0 22 22 c00022 pyruvate 1 1
1 24 24 c00024 acetyl-CoA 1 1
...
Convert Pandas dataframe to a [list], {dict}, {dict of {dict}}, ...
Per accepted answer:
node_df.set_index('kegg_cid').T.to_dict('list')
{'c00022': [22, 22, 'pyruvate', 1, 1],
'c00024': [24, 24, 'acetyl-CoA', 1, 1],
... }
node_df.set_index('kegg_cid').T.to_dict('dict')
{'c00022': {'kegg_id': 22, 'name': 'pyruvate', 'node': 22, 'vis': 1, 'wt': 1},
'c00024': {'kegg_id': 24, 'name': 'acetyl-CoA', 'node': 24, 'vis': 1, 'wt': 1},
... }
In my case, I wanted to do the same thing but with selected columns from the Pandas dataframe, so I needed to slice the columns. There are two approaches.
(see: Convert pandas to dictionary defining the columns used fo the key values)
node_df.set_index('kegg_cid')[['name', 'wt', 'vis']].T.to_dict('dict')
{'c00022': {'name': 'pyruvate', 'vis': 1, 'wt': 1},
'c00024': {'name': 'acetyl-CoA', 'vis': 1, 'wt': 1},
... }
node_df_sliced = node_df[['kegg_cid', 'name', 'wt', 'vis']]
or
node_df_sliced2 = node_df.loc[:, ['kegg_cid', 'name', 'wt', 'vis']]
that can then can be used to create a dictionary of dictionaries
node_df_sliced.set_index('kegg_cid').T.to_dict('dict')
{'c00022': {'name': 'pyruvate', 'vis': 1, 'wt': 1},
'c00024': {'name': 'acetyl-CoA', 'vis': 1, 'wt': 1},
... }
If you do "git status" while having a merge conflict, the first thing git shows you is how to abort the merge.
Just to add the information I was looking for: pragma mark
is Xcode specific, so if you deal with a C++ project that you open in different IDEs, it does not have any effect there. In Qt Creator, for example, it does not add categories for methods, nor generate any warnings/errors.
EDIT
#pragma
is a preprocessor directive which comes from C programming language. Its purpose is to specify implementation-dependent information to the compiler - that is, each compiler might choose to interpret this directive as it wants. That said, it is rather considered an extension which does not change/influence the code itself. So compilers might as well ignore it.
Xcode is an IDE which takes advantage of #pragma
and uses it in its own specific way. The point is, #pragma
is not Xcode and even Objective-C specific.
The oracle tag was not on the question when this answer was offered, and apparently it doesn't work with oracle, but it does work with at least postgres and mysql
No, just use the value directly:
begin
if (select count(*) from table) > 0 then
update table
end if;
end;
Note there is no need for an "else".
You can simply do it all within the update statement (ie no if
construct):
update table
set ...
where ...
and exists (select 'x' from table where ...)
This is gonna show all the stored procedures and the code:
select sch.name As [Schema], obj.name AS [Stored Procedure], code.definition AS [Code] from sys.objects as obj
join sys.sql_modules as code on code.object_id = obj.object_id
join sys.schemas as sch on sch.schema_id = obj.schema_id
where obj.type = 'P'
I am using a UIView extension , approach is close to @ChrisB approach above
extension UIView {
func updateHeight(_ height:NSLayoutConstraint)
{
let newSize = CGSize(width: self.frame.size.width, height: CGFloat(MAXFLOAT))
let fitSize : CGSize = self.sizeThatFits(newSize)
height.constant = fitSize.height
}
}
implementation : :
@IBOutlet weak var myTableView: UITableView!
@IBOutlet weak var myTableVieweHeight: NSLayoutConstraint!
//(call it whenever tableView is updated inside/outside delegate methods)
myTableView.updateHeight(myTableVieweHeigh)
Bonus : Can be used on any other UIViews eg:your own dynamic label
public - The members (Functions & Variables) declared as public can be accessed from anywhere.
private - Private members cannot be accessed from outside the class. This is the default access specifier for a member, i.e if you do not specify an access specifier for a member (variable or function), it will be considered as private. Therefore, string PhoneNumber; is equivalent to private string PhoneNumber.
protected - Protected members can be accessed only from the child classes.
internal - It can be accessed only within the same assembly.
protected internal - It can be accessed within the same assembly as well as in derived class.

There are no limits to the number of objects you can store in your S3 bucket. AWS claims it to have unlimited storage. However, there are some limitations -
That being said if you really have a lot of objects to be stored in S3 bucket consider randomizing your object name prefix to improve performance.
When your workload is a mix of request types, introduce some randomness to key names by adding a hash string as a prefix to the key name. By introducing randomness to your key names the I/O load will be distributed across multiple index partitions. For example, you can compute an MD5 hash of the character sequence that you plan to assign as the key and add 3 or 4 characters from the hash as a prefix to the key name.

I had the same issue too, the problem is exacerbated with the download link now only working for Visual Studio 2017, and installing the package from the download link did nothing for VS2015, although it took up 5gB of space.
I looked everywhere on how to do it with the Nu Get package manager and I couldn't find the solution.
It turns out it's even simpler than that, all you have to do is right-click the project or solution in the Solution Explorer from within Visual Studio, and click "Install Missing Components"
So, 10 years later this is still a thing :)
I've tried every answer on this page (ATOW)
and also some ILGenerator powered solutions (FastMember and Fast.Reflection).
But a compiled Lambda Expression seems to be the fastest.
At least for my use cases (on .Net Core 2.2).
This is what I am using for now:
public static class EnumerableExtensions {
internal static Func<TClass, object> CompileGetter<TClass>(string propertyName) {
var param = Expression.Parameter(typeof(TClass));
var body = Expression.Convert(Expression.Property(param, propertyName), typeof(object));
return Expression.Lambda<Func<TClass, object>>(body,param).Compile();
}
public static DataTable ToDataTable<T>(this IEnumerable<T> collection) {
var dataTable = new DataTable();
var properties = typeof(T)
.GetProperties(BindingFlags.Public | BindingFlags.Instance)
.Where(p => p.CanRead)
.ToArray();
if (properties.Length < 1) return null;
var getters = new Func<T, object>[properties.Length];
for (var i = 0; i < properties.Length; i++) {
var columnType = Nullable.GetUnderlyingType(properties[i].PropertyType) ?? properties[i].PropertyType;
dataTable.Columns.Add(properties[i].Name, columnType);
getters[i] = CompileGetter<T>(properties[i].Name);
}
foreach (var row in collection) {
var dtRow = new object[properties.Length];
for (var i = 0; i < properties.Length; i++) {
dtRow[i] = getters[i].Invoke(row) ?? DBNull.Value;
}
dataTable.Rows.Add(dtRow);
}
return dataTable;
}
}
Only works with properties (not fields) but it works on Anonymous Types.

From the jQuery documentation:
As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().
Just so others who have configured their apps like mine benefit from what I went through...
None of the above solutions worked for me because I have a ./config
directory just under my project base with 2 files:
application.properties
application-dev.properties
In application.properties
I have:
spring.profiles.active = dev # set my default profile to 'dev'
In application-dev.properties
I have:
server_host = localhost
server_port = 8080
This is so when I run my fat jar from the CLI the *.properties
files will be read from the ./config
dir and all is good.
Well, it turns out that these properties files completely override the webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT
setting in @SpringBootTest
in my Spock specs. No matter what I tried, even with webEnvironment
set to RANDOM_PORT
Spring would always startup the embedded Tomcat container on port 8080 (or whatever value I'd set in my ./config/*.properties
files).
The ONLY way I was able to overcome this was by adding an explicit properties = "server_port=0"
to the @SpringBootTest
annotation in my Spock integration specs:
@SpringBootTest (webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = "server_port=0")
Then, and only then did Spring finally start to spin up Tomcat on a random port. IMHO this is a Spring testing framework bug, but I'm sure they'll have their own opinion on this.
Hope this helped someone.
Use something like this:
page1.php
<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>
Any other PHP page:
<?php
session_start();
echo $_SESSION['myValue'];
?>
A few notes to keep in mind though: You need to call session_start()
BEFORE any output, HTML, echos - even whitespace.
You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.
The setting of the variable itself can be done in one of a number of ways:
$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];
And if you want to check if the variable is set before getting a potential error, use something like this:
if(!empty($_SESSION['myValue'])
{
echo $_SESSION['myValue'];
}
else
{
echo "Session not set yet.";
}
If speed is what you need and extra dependencies are not a problem, you maybe find numba
quite useful (now it is pretty easy to install, on any platform). The classic ray_tracing
approach you proposed can be easily ported to numba
by using numba @jit
decorator and casting the polygon to a numpy array. The code should look like:
@jit(nopython=True)
def ray_tracing(x,y,poly):
n = len(poly)
inside = False
p2x = 0.0
p2y = 0.0
xints = 0.0
p1x,p1y = poly[0]
for i in range(n+1):
p2x,p2y = poly[i % n]
if y > min(p1y,p2y):
if y <= max(p1y,p2y):
if x <= max(p1x,p2x):
if p1y != p2y:
xints = (y-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
if p1x == p2x or x <= xints:
inside = not inside
p1x,p1y = p2x,p2y
return inside
The first execution will take a little longer than any subsequent call:
%%time
polygon=np.array(polygon)
inside1 = [numba_ray_tracing_method(point[0], point[1], polygon) for
point in points]
CPU times: user 129 ms, sys: 4.08 ms, total: 133 ms
Wall time: 132 ms
Which, after compilation will decrease to:
CPU times: user 18.7 ms, sys: 320 µs, total: 19.1 ms
Wall time: 18.4 ms
If you need speed at the first call of the function you can then pre-compile the code in a module using pycc
. Store the function in a src.py like:
from numba import jit
from numba.pycc import CC
cc = CC('nbspatial')
@cc.export('ray_tracing', 'b1(f8, f8, f8[:,:])')
@jit(nopython=True)
def ray_tracing(x,y,poly):
n = len(poly)
inside = False
p2x = 0.0
p2y = 0.0
xints = 0.0
p1x,p1y = poly[0]
for i in range(n+1):
p2x,p2y = poly[i % n]
if y > min(p1y,p2y):
if y <= max(p1y,p2y):
if x <= max(p1x,p2x):
if p1y != p2y:
xints = (y-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
if p1x == p2x or x <= xints:
inside = not inside
p1x,p1y = p2x,p2y
return inside
if __name__ == "__main__":
cc.compile()
Build it with python src.py
and run:
import nbspatial
import numpy as np
lenpoly = 100
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in
np.linspace(0,2*np.pi,lenpoly)[:-1]]
# random points set of points to test
N = 10000
# making a list instead of a generator to help debug
points = zip(np.random.random(N),np.random.random(N))
polygon = np.array(polygon)
%%time
result = [nbspatial.ray_tracing(point[0], point[1], polygon) for point in points]
CPU times: user 20.7 ms, sys: 64 µs, total: 20.8 ms
Wall time: 19.9 ms
In the numba code I used: 'b1(f8, f8, f8[:,:])'
In order to compile with nopython=True
, each var needs to be declared before the for loop
.
In the prebuild src code the line:
@cc.export('ray_tracing' , 'b1(f8, f8, f8[:,:])')
Is used to declare the function name and its I/O var types, a boolean output b1
and two floats f8
and a two-dimensional array of floats f8[:,:]
as input.
For my use case, I need to check if multiple points are inside a single polygon - In such a context, it is useful to take advantage of numba parallel capabilities to loop over a series of points. The example above can be changed to:
from numba import jit, njit
import numba
import numpy as np
@jit(nopython=True)
def pointinpolygon(x,y,poly):
n = len(poly)
inside = False
p2x = 0.0
p2y = 0.0
xints = 0.0
p1x,p1y = poly[0]
for i in numba.prange(n+1):
p2x,p2y = poly[i % n]
if y > min(p1y,p2y):
if y <= max(p1y,p2y):
if x <= max(p1x,p2x):
if p1y != p2y:
xints = (y-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
if p1x == p2x or x <= xints:
inside = not inside
p1x,p1y = p2x,p2y
return inside
@njit(parallel=True)
def parallelpointinpolygon(points, polygon):
D = np.empty(len(points), dtype=numba.boolean)
for i in numba.prange(0, len(D)):
D[i] = pointinpolygon(points[i,0], points[i,1], polygon)
return D
Note: pre-compiling the above code will not enable the parallel capabilities of numba (parallel CPU target is not supported by pycc/AOT
compilation) see: https://github.com/numba/numba/issues/3336
Test:
import numpy as np
lenpoly = 100
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in np.linspace(0,2*np.pi,lenpoly)[:-1]]
polygon = np.array(polygon)
N = 10000
points = np.random.uniform(-1.5, 1.5, size=(N, 2))
For N=10000
on a 72 core machine, returns:
%%timeit
parallelpointinpolygon(points, polygon)
# 480 µs ± 8.19 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
0
instead of 1
(thanks @mehdi):for i in numba.prange(0, len(D))
Follow-up on the comparison made by @mehdi, I am adding a GPU-based method below. It uses the point_in_polygon
method, from the cuspatial
library:
import numpy as np
import cudf
import cuspatial
N = 100000002
lenpoly = 1000
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in
np.linspace(0,2*np.pi,lenpoly)]
polygon = np.array(polygon)
points = np.random.uniform(-1.5, 1.5, size=(N, 2))
x_pnt = points[:,0]
y_pnt = points[:,1]
x_poly =polygon[:,0]
y_poly = polygon[:,1]
result = cuspatial.point_in_polygon(
x_pnt,
y_pnt,
cudf.Series([0], index=['geom']),
cudf.Series([0], name='r_pos', dtype='int32'),
x_poly,
y_poly,
)
Following @Mehdi comparison. For N=100000002
and lenpoly=1000
- I got the following results:
time_parallelpointinpolygon: 161.54760098457336
time_mpltPath: 307.1664695739746
time_ray_tracing_numpy_numba: 353.07356882095337
time_is_inside_sm_parallel: 37.45389246940613
time_is_inside_postgis_parallel: 127.13793849945068
time_is_inside_rapids: 4.246025562286377
hardware specs:
Notes:
The cuspatial.point_in_poligon
method, is quite robust and powerful, it offers the ability to work with multiple and complex polygons (I guess at the expense of performance)
The numba
methods can also be 'ported' on the GPU - it will be interesting to see a comparison which includes a porting to cuda
of fastest method mentioned by @Mehdi (is_inside_sm
).

Use the <shape>
tag to create a drawable in XML with rounded corners. (You can do other stuff with the shape tag like define a color gradient as well).
Here's a copy of a XML file I'm using in one of my apps to create a drawable with a white background, black border and rounded corners:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffffff"/>
<stroke android:width="3dp"
android:color="#ff000000" />
<padding android:left="1dp"
android:top="1dp"
android:right="1dp"
android:bottom="1dp" />
<corners android:radius="7dp" />
</shape>
In a concrete class, declaration of a constructor for a concrete type Fnord effectively exposes two things:
A means by which code can request the creation of an instance of Fnord
A means by which an instance of a type derived from Fnord which is under construction can request that all base-class features be initialized.
While there should perhaps be a means by which these two abilities could be controlled separately, for every concrete type one definition will enable both. Although the first ability is not meaningful for an abstract class, the second ability is just as meaningful for an abstract class as it would be for any other, and thus its declaration is just as necessary and useful.
This is due the internet connectivity issue, i faced the same issue. I did a shallow copy of code using
git clone --depth 1 //FORKLOCATION
Later unshallowed the clone using
git fetch --unshallow
In Python, functions are first-class objects, this means: function references can be passed in inputs to other functions and/or methods, and executed from inside them.
Instances of Classes (aka Objects), can be treated as if they were functions: pass them to other methods/functions and call them. In order to achieve this, the __call__
class function has to be specialized.
def __call__(self, [args ...])
It takes as an input a variable number of arguments. Assuming x
being an instance of the Class X
, x.__call__(1, 2)
is analogous to calling x(1,2)
or the instance itself as a function.
In Python, __init__()
is properly defined as Class Constructor (as well as __del__()
is the Class Destructor). Therefore, there is a net distinction between __init__()
and __call__()
: the first builds an instance of Class up, the second makes such instance callable as a function would be without impacting the lifecycle of the object itself (i.e. __call__
does not impact the construction/destruction lifecycle) but it can modify its internal state (as shown below).
Example.
class Stuff(object):
def __init__(self, x, y, range):
super(Stuff, self).__init__()
self.x = x
self.y = y
self.range = range
def __call__(self, x, y):
self.x = x
self.y = y
print '__call__ with (%d,%d)' % (self.x, self.y)
def __del__(self):
del self.x
del self.y
del self.range
>>> s = Stuff(1, 2, 3)
>>> s.x
1
>>> s(7, 8)
__call__ with (7,8)
>>> s.x

You can use following commands to extract public/private key from a PKCS#12 container:
PKCS#1 Private key
openssl pkcs12 -in yourP12File.pfx -nocerts -out privateKey.pem
Certificates:
openssl pkcs12 -in yourP12File.pfx -clcerts -nokeys -out publicCert.pem
Starting with Swift 2, the enumerate function needs to be called on the collection like so:
for (index, element) in list.enumerate() {
print("Item \(index): \(element)")
}
I have mine set to "editor.fontSize": 12,
Save the file, you will see the effect right the way.

Issue: The Jet OLE DB provider reads a registry key to determine how many rows are to be read to guess the type of the source column. By default, the value for this key is 8. Hence, the provider scans the first 8 rows of the source data to determine the data types for the columns. If any field looks like text and the length of data is more than 255 characters, the column is typed as a memo field. So, if there is no data with a length greater than 255 characters in the first 8 rows of the source, Jet cannot accurately determine the nature of the data type. As the first 8 row length of data in the exported sheet is less than 255 its considering the source length as VARCHAR(255) and unable to read data from the column having more length.
Fix: The solution is just to sort the comment column in descending order. In 2012 onwards we can update the values in Advance tab in the Import wizard.

reduce
is just a function that will feed sequentially array elements to second argument of callback, and previously returned function to value, while for the first run, it will use value of second argument.
The only minus of this approach is that reduce will traverse every element returned by getElementsByName
even after it have found selected radio button.
You can fake it like this:
-- with column headings
select column1, column2 from some_table;
-- without column headings
select column1 as '', column2 as '' from some_table;
Use the TRY_CONVERT function.
Create a user defined function. This will avoid the issues that Fedor Hajdu mentioned with regards to currency, fractional numbers, etc:
CREATE FUNCTION dbo.TryConvertInt(@Value varchar(18))
RETURNS int
AS
BEGIN
SET @Value = REPLACE(@Value, ',', '')
IF ISNUMERIC(@Value + 'e0') = 0 RETURN NULL
IF ( CHARINDEX('.', @Value) > 0 AND CONVERT(bigint, PARSENAME(@Value, 1)) <> 0 ) RETURN NULL
DECLARE @I bigint =
CASE
WHEN CHARINDEX('.', @Value) > 0 THEN CONVERT(bigint, PARSENAME(@Value, 2))
ELSE CONVERT(bigint, @Value)
END
IF ABS(@I) > 2147483647 RETURN NULL
RETURN @I
END
GO
-- Testing
DECLARE @Test TABLE(Value nvarchar(50)) -- Result
INSERT INTO @Test SELECT '1234' -- 1234
INSERT INTO @Test SELECT '1,234' -- 1234
INSERT INTO @Test SELECT '1234.0' -- 1234
INSERT INTO @Test SELECT '-1234' -- -1234
INSERT INTO @Test SELECT '$1234' -- NULL
INSERT INTO @Test SELECT '1234e10' -- NULL
INSERT INTO @Test SELECT '1234 5678' -- NULL
INSERT INTO @Test SELECT '123-456' -- NULL
INSERT INTO @Test SELECT '1234.5' -- NULL
INSERT INTO @Test SELECT '123456789000000' -- NULL
INSERT INTO @Test SELECT 'N/A' -- NULL
SELECT Value, dbo.TryConvertInt(Value) FROM @Test
Reference: I used this page extensively when creating my solution.
The difference is, re.match()
misleads anyone accustomed to Perl, grep, or sed regular expression matching, and re.search()
does not. :-)
More soberly, As John D. Cook remarks, re.match()
"behaves as if every pattern has ^ prepended." In other words, re.match('pattern')
equals re.search('^pattern')
. So it anchors a pattern's left side. But it also doesn't anchor a pattern's right side: that still requires a terminating $
.
Frankly given the above, I think re.match()
should be deprecated. I would be interested to know reasons it should be retained.
You should remove web
middleware from routes.php
. Adding web
middleware manually causes session and request related problems in Laravel 5.2.27 and higher.
If it didn't help (still, keep routes.php
without web middleware), you can try little bit different approach:
return redirect()->back()->with('message', 'IT WORKS!');
Displaying message if it exists:
@if(session()->has('message'))
<div class="alert alert-success">
{{ session()->get('message') }}
</div>
@endif
To have a query working in any locale settings, consider formatting the date yourself:
SELECT *
FROM testbed
WHERE start_date >= to_date('2012-01-01','YYYY-MM-DD')
AND end_date <= to_date('2012-04-13','YYYY-MM-DD');
Bart Kiers, your regex has a couple issues. The best way to do that is this:
(.*[a-z].*) // For lower cases
(.*[A-Z].*) // For upper cases
(.*\d.*) // For digits
In this way you are searching no matter if at the beginning, at the end or at the middle. In your have I have a lot of troubles with complex passwords.
To solve the issue of customisation and appearance of the ticks, see the Tick Locators guide on the matplotlib website
ax.xaxis.set_major_locator(plt.MaxNLocator(3))
Would set the total number of ticks in the x-axis to 3, and evenly distribute it across the axis.
There is also a nice tutorial about this
* * * * * wget --quiet https://example.com/file --output-document=/dev/null
I find --quiet
clearer than -q
, and --output-document=/dev/null
clearer than -O - > /dev/null
Inject the request object into the controller using Laravel's magic injection and then access the function non-statically. Laravel will automatically inject concrete dependencies into autoloaded classes
class MyController()
{
protected $request;
public function __construct(\Illuminate\Http\Request $request)
{
$this->request = $request;
}
public function myFunc()
{
$input = $this->request->all();
}
}
If your request contains an object like this:
{
"year": 1900,
"month": 1,
"day": 20
}
Then you can use:
data class DateObject(
val day: Int,
val month: Int,
val year: Int
)
class LocalDateConverter : StdConverter<DateObject, LocalDate>() {
override fun convert(value: DateObject): LocalDate {
return value.run { LocalDate.of(year, month, day) }
}
}
Above the field:
@JsonDeserialize(converter = LocalDateConverter::class)
val dateOfBirth: LocalDate
The code is in Kotlin but this would work for Java too of course.
