## MT254 TMA 01

First TMA on MT264 (Designing applications with Visual Basic) got returned today – 96%. I’m very pleased with that and exceptionally lucky given that I read the material in a week, attended one on-line tutorial and wrote the assessment in a couple of days. I’ve … Continue reading

## Samsung NP-RV511-S02UK

I bought a new laptop the other week, a Samsung NP-RV511-S02UK. I have been using a Samsung NC10 dual booting Ubuntu and XP. An NC10 is a wondrous thing but when push comes to shove, a 1280×600 resolution is too small for Visual … Continue reading

## Sum of all the primes below two million

The sum of the primes below 10 is 2 + 3 + 5 + 7 = 17. Find the sum of all the primes below two million. Seemed pretty straight forward, loop through all numbers up to 2,000,000 – if … Continue reading

## Pythagorean triplet

Project Euler again, this time its problem 9. A Pythagorean triplet is a set of three natural numbers, abc, for which: $latex a^{2}+b^{2}=c^{2}$ For example: $latex 3^{2}+4^{2}=9+16=25=5^{2}$. There exists exactly one Pythagorean triplet for which a + b + c = 1000. Find the … Continue reading

## Sum of all even Fibonacci terms below 4 million

The second Euler problem concerns the Fibonacci sequence, which for anyone doing MS221 is the basis of module A1. Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, … Continue reading
