   $0 (along with $1 etc.) is used in shells, at least bash [and original sh?]. I think Perl just borrowed those, like $ prefixes to variables or not offering explicit subroutine arguments, from the traditional unix shell(s).

   I don't remember the exact ordering of events anymore but I was looking for a programming language alternative and stumbled upon lisp, and read PG's essays. Then shortly after, he introduced YC, and then I think HN was linked from

   The difference is that understanding what a gear is is not essential to the functioning of a car at all. You can completely remove it without loss for that particular user nor for the community of car users. Whereas not knowing that a URL i

   I think grandparent's point was that the part after the domain serves simply as identification of the information that is requested from the domain. Just like the foo in foo@bar.com identifies the user at that email domain. The user do

   Do you have references about the deterrence aspect or the relative usefulness? Are these public beliefs or scientific analyses or projections? The UK seems to have some odd relation to crime. Ubiquitous surveillance and fencing of just abou

   I think there's (pychological?) research suggesting that the prospect of life in prison is a stronger crime deterrent than the death penalty (and hence that it makes sense for countries not to have the death penalty for preventative re

    Thanks, I wasn't aware of QD-LED displays. It's sad to see Cd return to areas where LED technology seemed to bring an environmentally clean solution.

    The article mentions cadmium. This is the first time that I've heard claims that liquid-crystal displays contain cadmium, and actually I can't find anything on the web about it (other than an old patent that I'm not sure is r

    Some feedback: * don't use md5 as a security feature! I suggest to replace the use of md5sum with sha256sum (not even sha1sum is really safe anymore). The only use of seeing md5 in security contexts is to indicate that the person recom

    There's also the accelerometers, compass, perhaps more. X-Plane is basing the primary controls on those and I find it works amazingly well (I've been playing the Android version).

    I found/find it interesting that the Oberon system is written in a language that has garbage collection built in (the Oberon programming language). I haven't checked how it is dealing with allocation in interrupt handlers, though.

    I'm wondering about the timings on page 36 in the vector.pdf; those can't be seconds or it would be way too slow. (I've written a program[1] to calculate the mandelbrot set on the CPU with SIMD optimizations, and SMT support,
