I'm currently learning Ruby and need help in editing code to be more idiomatic. I have the method below I could use some pointers on how to make more "Ruby" :-)

days = %w(Mon Tue Wed Thu Fri Sat Sun)
days.each { |day| print "#{day} " }

I'm working on code for an assignment and I was hoping you all could point me in the right direction. Basically I had to write a program that will issue out a multiple choice test. Basically I'm trying to figure out how to error check my string switch statement. I have 4 options, A, B, C, D and i...
I have taken a number of screen captures of different interactions one would have with SE, specifically on the Code Review site. Here are some of my early observations.

I'm writing implementations of some numerical methods to solve linear equations systems, those implementations use the following Matrix class. I'm trying to get this class immutable, due to that the constructor and some methods create a copies of the backing two-dimesional array. The class have s...
I had a scale on scroll (background image) created, but if a user scrolls up and down very quickly, it flashes white boxes towards the header and/or footer. I'm guessing because the browser can't render the calculation fast enough. If drag the scroll bar up and down, that's no problem. But when I...
There are quite a large number of existing implementatons of FizzBuzz but I awoke this morning in a cold sweat with the terrible revelation that Code Review had no FizzBuzz implementation in Forth! To redress this terrible oversight, I wrote this while sipping my first cup of coffee.

In a qgis 2.0 plugin for windows, I calculate length and update a field with the values. It works, but takes a lot of time. Execution for this part only takes about ten minutes. Can anyone suggest anything to speed things up?

I've inherited an old PC from my girlfriend's dad and when setting up the printer I got a bit of a surprise:
Two questions spring to mind here:
Why does Windows think my wireless keyboard is a toaster?
Why does Windows even have an icon for a toaster in the devices menu?
I have written some vba to loop through a directory of 15,000 XML files and extract key information from these files into Excel - this is unbearably slow. Can someone please assist me in optimising the module?

the following awk code created in order to verify if free memory from top command is less them 20% from the total
I notice that actually I not need the "top -n1 | grep Mem |" , because FREEM and TOTALM parameters are inside the thired awk line
but on other hand I could not run the awk as:

While numbers returned from a single Random object are random with respect to each other, There is no guarantee that sequences returned from different seeds will not be correlated in some way. Perhaps this is the problem if you are generating just a few numbers before restarting the program.

On my test system, the output of top -b -n1 | head looks like this:

I'm focussing on trying to write clean, modular python 2.7.5 code. I have written the following code:

patient = [d['patient_family_member_id'] for d in dataPatient if d['id'] == sys.argv[2]]

//Math function returning a random number
public int randWord(int length) {
return (int)(Math.random() * length);
}
A better way to return a random number is to use the Random class. random.nextInt(length); is preferred. Also, this method does not need to be public, it should be private as ...
I have made this TicTacToe game where you play against the CPU. But the CPU's move is sometimes invallid and the game crashes. Can anyone help me to write a better function for the cpu move? Not that you have to write it for me because I want to learn this myself.

I'm trying to figure out how to nicely write a Winforms app that reports the progress of completing a long task onto the main form's controls without causing Cross-thread op exceptions and such. So far I've come up with this scheme which at least works, but doesn't look very nice:

So I've been kinda chewing on this since your email, because... It's one of those simple questions that defies a simple answer. You're not the only person to raise this concern, of course: several respected users, moderators and even co-workers have expressed dismay upon seeing reasonable questio...

This is an iteration of my previous question: Concurrent Task Waiter

I want a whole city to be on drugs secretly, so they don´t know they are drugged by their government.
The city is about 2 billion people and roughly structured like a Makropole from the Warhammer 40k universe. This means:
