In the field of computer science Donald Knuth is highly respected.

Until recently I had been keenly unaware of his profession of Christianity. He gave a series of lectures titled God and Computers: Things a Computer Scientist Rarely Talks About, which was eventually compiled and published as a single book. Much time is spent expounding upon the things he learned - both as a Christian and as a computer scientist - while authoring another book, 3:16.

Recordings of the lecture series had originally been available through TechNetCast, but that archive has fallen into terrible disrepair. Much searching brought me to contact a stranger who had posted to his blog that he had kept these recordings. He replied the same day with a link to a "fake" RSS feed he had set up for the lecture series. You can find those recordings here. Be aware this is more than 10 hours worth of audio.

If the above link no longer works for you, e-mail me for copies of these recordings.

I've added a small (and inexpensive) project to my list: restoring a small 70s guitar amplifier. The amp in question is a Marlboro Sound Works GA2.

I've gone over all the electronics and it looks like I may need to replace a few components, but nothing major. The total cost for replacement components should be no more than $10.

The short list of things to be done:
  1. replace fuse: 120/250VAC @ >~77mA & holder (?)
  2. clean potentiometers
  3. new power cable, grounded this time
  4. transistors are suspect. maybe replace?
  5. capacitance test, replace leaky capacitors
  6. replace bad resistors
  7. replace power toggle
The whole operation should go fairly quick. I'll keep you posted.
