This is me singing “Let Me Entertain You” by Robbie Williams at last night’s Rockaoke event.


Rockaoke is, of course, Karaoke, but with a live rock band.

This was just one of several public singing performances I took part in this week …


Ferrari Day

Wednesday, March 14th, 2012

This is me burning rubber around the International circuit at Silverstone in a Ferrari 360.

Sadly, this isn’t my car, as you can no doubt tell from the owner’s name written all over it. However, thanks to my brother generously buying me a Ferrari Driving Experience for my birthday I was able to take it for a couple of laps before I had to hand the keys back.

So, what’s it like to drive?


Kinetica 2012

Adrian in Mirror

This is an unedited photograph of me showing my reflection in a moving distorting mirror. I took it at this year’s Kinetica Art Fair.

The light wasn’t great for taking pictures, and there were crowds of people there, too, so I only took a couple …


Programming Challenges 4 - 6

Tuesday, November 8th, 2011

Following immediately on from the previous challenges, I had hoped to redeem my rather miserable performance on Challenge 3.

Read on to see how I did with Challenges 4 - 6.


Programming Challenges 1 - 3

Tuesday, November 8th, 2011

I downloaded a copy of Skiena and Revilla’s book Programming Challenges from here. I wasn’t hugely taken by the book as it is mostly about coding in C, rather than C++ which I prefer, so I’ve only really skim-read it. However, I did take the time to solve some of the challenges after the first chapter, which was a far more valuable learning experience.

I decided that as the first few challenges looked fairly straightforward that I would make it my goal to solve each one 100% correctly on the first go. Unlike the Ancient Messages challenge where comprehensive test data was supplied, this time each challenge only came with one or two examples. This means that coming up with a good way to test the program is essential if one wants to pass the judge’s tests first time. In a programming competition failure to pass tests means a time or score penalty. But I’m more concerned with real life where a programming error could mean death, financial loss, or worse, the wrong coloured background on a dialog box!

So, how did I do?


Programming Challenges - Ancient Messages

Monday, November 7th, 2011

Earlier this year I wrote about Project Euler. I’ve kept up my problem solving, with an additional 23 Project Euler problems solved in the four months since I wrote that article. I’ve also tackled some problems from other sources that don’t have restrictions on me writing about them.

First up, I had a bash at one of the easier looking problems from this year’s ACM International Collegiate Programming Contest. You can see a description of the problem here on the UVA Online Judging website which provides automatic verification of submitted solutions.

The solver’s task for the problem I chose is to decode some “Ancient Messages”. So, how exactly did I do that?


High Quality Rock is here!

Friday, July 22nd, 2011

I’ve just spent a very pleasant forty minutes listening to Deep Purple’s classic rock album, Machine Head. Exciting on a good day, but today it sounds extra special as I’ve been listening to a brand new high quality re-release of the album in 24 bit / 96 kHz download format.

So, why is this so exciting?


Project Euler

Thursday, July 7th, 2011

Project Euler is an internet-based mathematical and programming challenge that has been running for the last ten years. Problems set on the site range from incredibly easy to (mostly) very difficult. I’m currently at “Level 3″, having solved 110 of the problems, including some of the more recent difficult ones.

It’s a bit tricky to write about this little hobby of mine as one of the conditions of taking part is that one doesn’t give away the answers.


Rock Choir - Wembley Arena 2011

Sunday, May 15th, 2011

Unquestionably the most exciting thing I have done so far this year - this is the audience I sang for earlier today:

Rock Choir

The picture shows a capacity crowd of ten thousand people (mostly women) filling Wembley Arena for this afternoon’s Rock Choir Live event.

Plus, there’s breaking a Guinness World Record, recording a track to be released on a deluxe version of the existing Rock Choir: Vol1 album and not only that but it has all been filmed for a documentary to be broadcast on ITV later this year. Not bad going for one afternoon!

So, what’s the story? How did I come to end up on stage in front of that many people?
