Old Mac Pro 2008 FB-DIMM DDR2 RAM

10.20.2014 – Mac Pro, Job & Analog Filters

Oops… My Mac Pro failed to boot up today as one of the RAM modules got corrupted. First time I have had to deal with that! Actually, I’m glad that was *all* it was! But, a few hours of pulling RAM sticks and trading DIMM slots eventually got it back to passing the POST. Now, I need more RAM! I doubt my sessions in Pro Tools will operate, now. Time for a few more Gigs.

And, actually, I’m feeling a bit stressed with my project at work. There’s just a lot of code to write before Friday. And, I have to have some semblance of a cross-browser solution with animation intact by Monday. I committed, I’ll deliver – I’m just working on the game plan as I move forward.
Today, after work, I was still in that kind of frenzied mindset. But, I finally settled in to the analog filter design book a bit – did some calculations, found some better techniques to choose capacitor and inductor values, solidified my Bessel and Butterworth knowledge, and tried to translate all that I learned into applying to Audio frequencies.. It’s not that I’m not interested in RF, it’s just that I don’t have an application right now, and it’s not my primary discipline.  And, it’s quite complex.  But, all-in-all, I can certainly see how the higher frequency signal you get, the crazier to control the signal gets! And, the sections on PCB trace filters was pretty mind-blowing for high frequency – how they can mold the traces into patterns to try to maintain signal integrity. Niice.
