A/B Box

Last night I built an A/B box for my guitar setup (to switch between two signal paths, usually effects->Amp A/Amp B or Guitar -> Signal Path/Tuner. It was a first little foray to see if I could do something like this. It worked out pretty well – I got a diagram from www.fulltone.com and pretty much copied it – I got most of the parts from pedalparts – although with the exception of the 3pdt switch you could get them all at frys for about $15. if it’s not plugged in to power, the LED’s don’t work, but for some reason, the power seems to add a tiny bit of noise. I’m not sure why yet.

Technical Books, Languages, and Project Euler

First things first:
Hi. How have you been? Ok, Honestly, I don’t care.

Moving on.

I just got some new tech books: Programming Erlang (semi-work related), Programming Pearls (2nd edition) and Beautiful Code.

I started working on Programming Erlang but stopped a few chapters into it. For someone that has thought exclusively in OO for the last 10 years or so, trying to remember that = is a pattern matching operator is f’d up.

Anyways, a couple weeks ago I started to do Project Euler to learn a bit of python, and plowed my way through a bunch of the first problems (20-30) – they were mostly easy, even though my math stops at grade 12 – a few I ran into constraints issues where I actually had to think my way through the problem, or, even more rarely, find a mathematical explanation of the problem in order to write an algorithm. (the two triangle problems caused this. )

Python is a pretty cool language, very easy to learn.

Anyways, I had originally started this post with the desire to write a list of books I can’t do without, but I kinda got sidetracked. By Work.

An Update on a Canadian Legend

There is a piece of literature that is a piece of historical and cultural significance, called The Sweater. It’s taught to kids in canadian schools, was made into a short animated film, and is even commemorated on the back of Canada’s 5 dollar bill. I read it to my kids and am trying to instill in them the national pride of Canada, and our innate hate for the Toronto Maple Leafs.
