Holy, long time since I've written. Time to do some more writing of our current projects

Working on FPC a bit still, but mainly working on our new project seed. More information to follow

Cool! I just made a program way way way faster! This is FPC, specifially reading in a .fpc database with markers in it. It used to take a hour and a half to read in a database on a Sun, and 20 minutes on a 1GHz AMD-K6. Now it takes about 1 minute! I've been working on this for the past three days, the first day was just getting my bearings, yesterday I tried another approach that still did the adding in O(N^2), even though I thought it would be lots faster, it wasn't, and I was sad. Last night, I must have figured it out in my dream, cos' when I woke up, I knew the answer. It only took the morning to do the code, and now it's O(N) and way faster. Cool!

Whew code is going really well again today, made a first test version of a simple band identification routine. Really simple, yet it works very well, almost as well as Bandleader does... I've put up a snapshot. The algorithm is from a small part of Bandleader, the algorithm there is:

% Function to find all local peaks in a vector. A local peak isdefined % as a value x(n) satisfying x(n-2) < x(n-1) < x(n) > x(n+1) > x(n+2), % and for which the peak amplitude is greater than twice the local mean, % where the local mean is taken over +/- m samples.

Got a cute little quickcam, updates every now and then at snesscam. Check it out.
