We are introducing to you some of the speakers of the next Berlin Buzzwords conference 2015. Therefore, we are interviewing #bbuzz speakers ahead of the conference. See what they responded …

Get to know Andrew Clegg.

How did you get started with developing software?
I first started coding on a Sinclair Spectrum with 48KB of RAM in the early 80s.Yes, kilobytes.I was about 7 years old I think. You had to plug it into your TV, and into a domestic cassette recorder for loading and saving data. It had weird rubber keys that squished instead of clicking, but a crude form of context-sensitive autocomplete, for BASIC keywords at least. Good times.

What would you like to accomplish by giving this talk?
I'd like people to come away with an understanding of the challenges of pattern matching and anomaly detection in timeseries data, and some idea of how they can take the tools we've developed to help with these tasks and apply them to their own data.

Have you enjoyed previous Berlin Buzzwords editions?
Very much! I tend to gravitate towards the quirkier talks in the smaller rooms which cover interesting algorithms, useful data structures etc... But always with an eye on scalability and real-world applicability. 
Last time I went, it was at the Urania centre – so I'm really looking forward to returning, and seeing how the Postbahnhof compares.

Anything you are planning to hack on during Berlin Buzzwords?
I'm planning to release a library of high-performance timeseries algorithms, as part of our ongoing Kale project, which I'll talk about in my session. Hopefully, this will already be out before I arrive, but if not, then I'll be putting on the finishing touches for a first release. (And if it is out, I'll be dealing with the inevitable bug reports...)

What did you enjoy the most, when you in Berlin?
I'm a big fan of Berlin, its mix of old and new, and its blend of culture, history, and great parties. The Technology Museum and Computer Games Museum are great geeky days out -- the latter even has some old Spectrum games from my youth. The old air raid bunker underneath Gesundbrunnen station is a fascinating experience. And for the first-time visitor, the Wall is a must-see, of course.
