I have written a functional GUI program using PyQt4, and I'm looking for some feedback because it's not as fast as I would like. It takes in some number of large, same-sized 2D arrays and displays a sub-image of each one in its own sub-window - at full resolution or only zoomed by a factor of 2 ...

This works, and the UI is snappy in the simulator, but since this is my first time really using GCD, I'd just like this code to be reviewed before I start using it everywhere. Note that this is inside a PFQueryTableViewController
my function
func tableRefresh() {
// get quality of...
I agree e-mail addresses should not be posted. However, such a filter would undoubtedly hit a lot of innocent posts as well.
I do not dare to guess how many posts there are on SO alone about matching e-mail addresses. Communicating about such questions and answers is going to get though if you f...
Factorio is a game about building factories and about automation. Items can be crafted (just like Minecraft) yourself, or automated by assembling machines. To help me expand my factories I created a little script in Python 3 that shows me what other items that I can produce once I create factory ...
Recently, I've written a code, which implements sticker window function.
There are some duplication codes as you can see. I think this code can be simpler or else other. Could you tell me your thought? Thank you.
// If 'rtParent' and 'rtChild' are closed each other as 'ENABLE_STICK_VALUE', retur...
Here is the code:

I am new to Webapplications and threadsafety. Please, could somebody tell me if the following example is threadsafe? My main concern is that the AClient and ParameterValidator are autowired by Spring as singletons (not threadsafe) and as far as I understand all incoming requests will share the sa...
I'm doing code review, and seeing method declarations like that:
def __init__(self,data):
I always thought that it should be formatted like this:
def __init__(self, data):
But then I checked PEP 0008 and see no exact statement about that. There is guide about whitespace around operatos, and...
Refactoring some old code with new VS2015. Can't figure out how to use the power of string interpolation here (to remove string.Format):
public string AsVolts(double value, string format = "0.0")
{
if (double.IsNaN(value) || double.IsInfinity(value))
return "";
return string.Form...
It's easy to write a function that adds two ints in F#:
let add x y = x + y
Actually it's the same as:
let add (x:int) (y:int): int = x + y
If you need it to make generic so that it can take arguments of other type than int,
you should use inline keyword:
> let inline add x y = x + y;;
va...
I am trying to get an answer to the two quite similar questions here:
Should I convert an entity to a DTO inside a Repository object and return it to the Service Layer?
or
Is it okay to return DTO objects from the Repository Layer?
Right now I am stuck in my Servlet (Servie Layer) th...
import this will generate the Zen of Python, which has two relevant lines:
Beautiful is better than ugly, and
Readability counts.
For me, and for many of the projects I touch, this means I should put the space after the comma.
Best of luck!
I wrote a blog post on this subject where I go more in depth because I found it intriguing. You can find my original answer below.
You can specify a custom entry point to the linker with the -Wl,-e,entry_point option to gcc, where entry_point is the name of the library's "main" function.

Using Java 8 you can do this in a very clean way:
String.join(delimiter, elements);
This works in three ways:
//directly specifying the elements
String joined1 = String.join(",", "a", "b", "c");
//using arrays
String[] array = new String[] { "a", "b", "c" };
String joined2 = String.join(",",...
I wrote a script do you think it works well. I.e. do I need to close database / connection at the end? The goal is to be able to upsert many records and delete many records in one shoot.
Here is is an example HTTP POST request with JSON body to use it:
{"db" : "Memorise", "upsert" : [["Diagram"...
$args = array( 'hide_empty=0' );
$terms = get_terms( 'issue', 'orderby=id&order=DESC' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ) {
$count = count( $terms );
$i = 0;
$term_list = '';
foreach ( $terms as $term ) {
$i++;
$term_list .= '<a href="' . get_ter...
Sparked by this meta, I did a quick search for "socket.io" and came back with 21 hits. It seems to be enough to create a tag for it IMO, but I'm no web guy. I don't really understand what this framework is and if it really applies to these questions.
A lot of these questions are currently tagged...
