A few tips, but there may be more. These are just the things that immediately jumped out at me:
Break out AsyncTasks into their own class
With multiple tasks, it might be better to make them each their own class/file. You can call back to the main Activity with listeners. If you must keep...
Jon Skeet hit 1M total rep on Area 51.
And apparently has 7 bronze badges.
Something has to be done.
This code outputs the smallest number with more divisors than the input:

p = length(lagcof);
X = zeros(numpath, lengthpath + p);%pathes, the initial p elements are given.

Code from my last project, that have to work on python 2.7 and python 3.
I want to get a path as a unicode string from argparse :
parser = argparse.ArgumentParser(

I've read about mediator, event aggregator, using, backbone.events ...etc
I need advise about another potential pattern below, do you think this is evil ? or good ? if not good what are the caveats/problems.
This 'pattern' answers a very classical issue. When you click something on View1 , View...
Let's pretend the following:
<?php
// Functions to validate/sanitize user input
function validateUsername {
// If accepted, return true, else return false

function validateEmail {

First some code style points:
Declare your
variables! Not only
does it help prevent a slew of bugs from cropping up, it makes it a
lot easier to read and understand what your code is doing. Looking
at only the code that was posted, I have no idea if they are local
or global scope or what data t...
I have written my first program in go. It's rewritten from python.
Program takes csv file, emulates query SELECT X, Y, SUM(Conc), SUM(ToxConc) FROM very_big_table GROUP BY X, Y. And runs on terabytes of data.
It's written messy, but runs 100x faster than same program written in python.
Here...
I want to parse a glob-like pattern (only the brackets functionality actually) and fetch all possible combinations of this pattern.
Something like perl -wE 'say while glob "{a,b,c}"'
I have managed to implement it in ruby but it's quite a big code.
Do you guys have some tips on trimming that do...
I have been using NLog for logging purposes in my Web applications, but it was not injectable. More precisely, each class using logging declared the logger like this:
private static Logger logger = LogManager.GetCurrentClassLogger();
Since my logging is very simple, I have defined some extensi...
I have a python script that runs 3 compiled programs and make them communicate via standard i/o. This is my first time using pexpect and I am not so good at python. My program works very slowly. Is there anything that I can do to fasten that program without changing others? If not, I'll try to do...
I have some code as follows:
$condition = true;
while($condition) {
$condition = doSomething($something);
if($codition) {
break;
}
$condition = doSomethingElse($somethingElse);
if($condition) {
break;
}

// $condition is true because we haven't exited the loo...
I have implemented a filter for filtering a IEnumerable of a specific type.
To accomblish this goal i have created three classes: FilterOption, Filter and the FilterManager.

public class FilterOption<TFilterOptionType>

public bool IsSelected...
My code is very slow to run, and I am trying to find a way to make it more efficient. I know there must be a better way than to write each modulo operation.
def divide
z = 0
test = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
(2..Float::INFINITY).each do |x|
if x % 2 == 0 && x % 3 == 0 && x % 4 =...
