Sometimes I worry about the accuracy of webcomics...
So today is the start of the rest of your life. Seems kind of appropriate today. Had a meeting with my PhD Supervisor to start to develop my project. Of course at this point it would help to explain what the project is, but I can’t right now, so shush. Continue reading →
As part of any major project, it occasionally happens that you assume something is a ‘solved problem’ when its really not.
Ok, its been a busy few weeks, and I’ve let the blog slip again, but coming up:
I had been looking at this years Google Summer Of Code google group and saw the list of organisations that are getting involved. While i was alooking at it, I knew i didn’t want to even consider the big boys (I’m looking at you, Debian, Drupal, KDE, Apache, X.Org, etc), they’re too big to get my teeth into, and I’m currently in the throws of ‘WHAT THE HELL AM I GOING TO DO MY FINAL YEAR PROJECT ON!!! ‘ (For any Americans, that means ‘dissertation’).
My university is big into networking etc, so I had a look at the NS-3 Network Simulator, which currently sits at slightly less that 2 million lines of code, and is vaguinly within my realm of interest so I’m going to see a) if i can get it to work and play with it for a bit and b) if i can contribute anything to the project and parlay that into a final year project, and I’ll be documenting whatever progress I get on this blog.
I doubt that I’ll apply to GSOC as I don’t think I’d be able to give the required time committment over the summer. 
Anyway, Next blog post will be a start into the installation and configuration of NS-3 on my virtualised Ubuntu setup.
So I have a piece of coursework for a CS module I’m taking at Queen’s University Belfast and one of the focal points of it is the recent RockYou! SQL-injection breach that released 32million passwords into the internet, and I thought I’d have a closer look at that list.
If anyone is interested in Erlang B Calculations, very relevent to any communications or engineering students, I’ve written a little quick piece of code to calculate them.
There are several levels of functionality in the code.
Erlang B itself only has 2 variables, System load in Erlangs, and the number of “trunks” (read: servers/call center operators/phone lines), and its output is a blocking probability from 0 to 1
All three of these variables or none atall can be defined at runtime;
The code uses the unistd.h library for argument parsing so is more or less unix only (or cygwin alternativly) and long doubles for more or less everything inside the code.
Having tested the limits, it kinda conks out then calculating large (read 1000 erlangs) on large trunks (got as far as 1234 trunks, then died)
When i get a bit of time i might optimise the factorial part so it doesnt run thru the entire factorial sequence for each number.
Anyway, the code is here. I’m not wasting my time laying out code on blogger.
