I was looking for short advice on my coding. Since im planning for the long run, to get a job as a Android Programmer.
This is my first calculator app, which I did by self learning Programming. I have no other Programming Langauge experience.
So I would love to hear how bad my coding is?
Which ...
I feel like this bit of code could be condensed or made better in some way. It may in fact not be but
figured I'd get some people smarter then me to have a look. I have multiple pages on my site and in certain
pages I'm setting a js variable:
var header_check = "user-profile";
Some pages I'm...
Implementing basic sorting algorithms to learn them, and coding, better. Criticisms/ critiques welcome. Also possible optimizations.

First off, your code really breaks down to this logic and I find it helpful to write it out the longer version to full understand the logic flow before trying to shorten it:
var header_cookie, cookie_check, city_profile, state_profile;
if (typeof header_check !== "undefined") {
header_cookie...
I have a big in-memory collection of following simplified class:
public class Product
{
public int Id { get; set; }
public string UserName { get; set; }
public int CategoryId { get; set; }
public string Title { get; set; }
public string Description { get; set; }
}

The character set is named ISO-8859-1, not ISO-8895-1. Rename your function accordingly.
Change the return value to be more informative:
Return 0 on success.
If max_size is too small, return the minimum value of max_size that would be sufficient to accommodate the output (including the traili...
In December 2013 we held a bunch of weekly weekend-challenge events, which was fun, and generated posts that made it to the site's newsletter, week after week. One may want to tweak this query so as to filter posts created before December 30th, 2013.
Some weekend-challenge stats up to that date:...
Just looking over the two functions, I would probably say the first function is a better practice. It's shorter (meaning it's more maintainable), it uses fewer variables (which can cause less confusion), and does the same thing as the second function. Overall the advantage is that the first func...

Instead of using both 3 and 5:
if (i % 3 == 0 && i % 5 == 0)
you can just use 15:
if (i % 15 == 0)
You're also supposed to print the number by itself if neither case applies:
else
println(i)
For your existing cases, however, you're only supposed to print the message.
Final solution...
Firstly, to answer your first question, QString is definitely not immutable. Directly from the documentation:
This operation is typically very fast (constant time), because QString preallocates extra space at the end of the string data so it can grow without reallocating the entire string eac...
Going for short'n'sweet, here's my effort (it absolutely won't win any prizes for performance!):
void Main()
{
var rows = 10; // Including a 1-cell border o'death.
var cols = 10;
var rnd = new Random();
var cell = new int[rows, cols];
Do(cell, rows, cols, (r, c) => { cell[r, ...
First off, here's the code:

@autoreleasepool {
NSLog(@"Enter Player 1 Name:");
NSString *playerOneName = [PSInputHandler ...

Problem description.
Returns strings with probability determined by the frequency
of each of the strings.
eg: if "foo" has weight of 50% and "bar" has weight of another 50% then both foo and
bar should be 5 and 5 times each given that 10 tries were made.
If question is unclear let me know I wil...
What should we do with:
Short answers (for example, "I suggest you use [hyperlink to this standard API] instead.")
Code-only answers (for example, an improved version of the code in the OP)
Such answers could be improved (e.g. by adding an explanation of why the suggestion is helpful).
Is it...

I made a lingo game using Python:
You guess a word, and if its letter(s) is in the same spot as a hidden word's, you add [] around the letter. If it's in the hidden word, but not in the same spot, you add()).
As of now, I have a whole bunch of loops and some code which I find makes the program...

I am trying to read a single-columned CSV of doubles into Java with a string header. It is 11 megabytes and takes over 15 minutes to read, which is clearly unacceptable. In R this CSV would take about 3 seconds to load.
This CSV file may contain strings so I am parsing it with this in mind.

My question concerns the following python code which is already working. As far as I have seen, there are very elegant solutions of compacting code. Do you have any ideas on how to make the following code look smoother?
