Perhaps Queens should offer Amazon a pile o' money to build their new HQ somewhere else, anywhere else!

You don't need cons, car, cdr, etc. They can all be implemented using lambda. For example: ;; excuse my possibly hybrid notation (defun cons (car cdr) (lambda (m) (if (eq? m 'car) car (if (eq? m 'cdr

Disgusting indeed: A way to write irreducible loops that doesn't use a goto. Good idea to measure the resulting code, given how poorly most optimizers deal with such loops. Even sadder because the same effect can be achieved cleanly (a

I found lots of things that ran much faster on the Tera than on a PC. But yes, if you are happy with the performance of a general-purpose machine, then there's little reason to take on a super. Machine-room requirements alone would fin

Yeah, lots of people didn't try. What it provided was a way to get over 90% utilization of the processors (every processor issuing useful instructions most every clock tick) without worrying about cache misses. So relatively simple cod

My impression, for computer science PhDs in the US, is that there's generally plenty of funding. On the other hand, they may have to search among professors and schools to find it.

There are several conferences and journals that will accept submissions from open-source developers (or anyone else). Many have a blind reviewing process, so the lack of a famous name/affiliation shouldn't have an effect. Classic

Franz mentions Wirth's metric for compiler quality: Speed of self compilation. I first heard this idea, in a slightly different form, from Vickie Markstein (part of IBM's 801 team) in early '88. She suggested using this idea

Yeah, well, the Army can make anything boring, painful, and stressful.

Rounding to the nearest second would be fine. Including the pace for 400 meters would be nice for track-oriented users.

If it's hot (say, above 70 degree F), a well-trained man can out run a horse over a long distance. If it's cold, the horse will win. The horse's cooling is largely dependent its breathing which is constrained by its pace.

I don't see police much. But I agree that the police batons I see advertised for sale seem to be metal collapsible things, though I never find a weight mentioned in the adverts. How much lead has been added to the tip? An alternative I

Pardon my rant, but... People say "baton" and I always think of the lightweight tube runners carry around a track. In this context, a baton is a nightstick. Have you ever examined one? A friend showed me his grandfather's. It

But it's not true - the interesting components (the op amps, multipliers, etc) all have bandwidth limitations.

There's lots of pathologies to watch out for... Imagine sorting 10 million random ints, where 1% of them are random 64-bit values and 99% are in the range [0..9]. Might be extra fun in parallel.

Indeed, I was 30 and my brain was still plastic. Really, the only notable thing from my post was the fact I'm still using the same Latex manual after all these years. Kinda ragged now, but still useful.

I'm over 60 and have been using TeX since '85. Same manual after all these years... I still seem to be able to learn new stuff, though it's not always clear it's worth the bother.

Don't think so. Here, Cadence refers to "Cadence Design Systems". "Cadence Research Systems" seems less clear. In any case, Chez Scheme was the long-term project of Kent Dybvig.

I believe that I can't see that wavelength, but the energy has to go somewhere (similarly, I can't see microwave radiation, but don't want to put my head in a running microwave, a la Infinite Jest). I think the better questio

And TRAC is all about macros... TRAC is lots of fun. I read about it in Nelson's book, Computer Lib/Dreams, when I was a freshman at Illinois. That spring, my Dad bought an Altair and I wrote a version of Trac for it, in assembly.

I met a man who was a long-haul trucker on the Eyre Highway, across the Nullarbor. Sounded bad, but the Stuart Highway looks worse!
