Comment Really? (Score 1) 272

Look, we already know that genetic diversity doesn't increase at any predictable rare. For most pf life's existence on earth it was limited to anaerobic bacteria and that there was very little genetic diversity. Then the oxygen levels in the oceans and atmosphere reached saturation levels and aerobic live took over. And with the higher complexity of possible life forms, the increase in reproductive frequency, and the over-all speedup of this rocket-fueled form of life genetic diversity exploded.

Comment Design with clustering in mind (Score 1) 274

While I agree with everyone that says build small to start and scale up later as needed, the one caveat I'd give is whatever technology you use, design with the THOUGHT of clustering from the start. I've seen many designs fall down when scaled because, for example, the app used session too liberally and now session replication across clustered nodes is a serious problem.

There's nothing that says you must use clustering later, there's other approaches, but if your app inherently can't be clustered because your design doesn't allow for it the it can turn into a real headache quickly.

If you design as statelessly as possible then you're likely to be fine when you go to scale, whether vertically or horizontally. That's a simplistic answer, but it will be correct, to a reasonable approximation of "correct" :)

Let's see... if we stay just with Intel: 8086 4.7Mhz, 80286 (forgot the speed), 80386SX 20, 80386 33, 80486 DX2/66, Pentium 133, 233, Celery 350 (2, one overclocked to 400), P3 500ish, and a slew of Core X and iX chips, and my Xeon-fueled Mac Pros.

If we open it up to other CPUs, well, how much time have you got?

They left the binaries in RAM, so just a reboot would remove them. They also left a text file with contact info and an explanation in, and they didn't take data from the affected systems, they used the systems to probe other IPs.

There's not really a physical analogy that fits here but the only damage they did to each individual device would be to slightly raise it's power consumption and bandwidth usage. Insignificant to any individual, although it might well have added up to quite a lot.

I have a couple of exercise bands at my desk which I use when my hands are free. They don't take up much space, and you can get some with pretty decent resistance. You could also get a couple of ~8-10 pound exercise balls; tossing those from hand to hand can be a pretty decent light workout. Standard free weights are an option too. Honestly, you're just not going to get a lot of cardio in while at your desk. But you can do some light strength training and toning, which will help keep your metabolism up a bit if nothing else.
