Back when CPU speed was in MHz and not GHz I purchased an ABit BP6 dual socket motherboard and a couple of 300 MHz Celeron CPUs. Those particular ones were just fine to overclock to 450 MHz. So I had a 900 MHz dual CPU machine running Linux back when most were running Windows95 on a single CPU machine at less then 500 MHz. Didn't take long before the advances in hardware caught up and I replaced it. But it was fun to build and tinker with and was still being used by my kids 10 years later.

When I code at night (away from my day job) a beer an hour is what I use to control the amount of code I write. Not enough to alter my thinking or dexterity, but after about 4-5 hours I'm either getting too tired from the beer (going to bed) or I've had enough to want to stop coding and focus more on the drinking. I use to drink coffee, stay up for hours and code but then I was no good the next day. This way I can get some work done but it also lets me have some fun (or a good nights sleep).

I was in a boardroom on the 6th (top) floor of our building for a 1:30 pm meeting and just as we're getting underway the table and chairs were shaking. Was pretty heavy for about 20 seconds and then faded off over the next minute. We're a lot of government buildings so the policy is to evacuate. We actually tried to continue our meeting but then they finally got to our floor to check it out they found us and told us to leave. As you can guess, no more work is really being done today. It's pretty exciting for us as we don't get this here.
One interesting note, when I did go outside most everyone was on their cell phone and several were stating that they couldn't get service. I would guess because of the increase in volume at that time.
