The article kind of misses the forest for the trees: just as today, diet was associated with various conflicting theories and advice - some reasonable, some pure fabrication. In absence of much hard evidence food becomes a playing field for

Around 1990 I had the fortune to learn Parallel-C - a language that was designed during the Transputer hype and was essentially C extended by a few features to support easy parallel programming. My favourite feature was par(<start ex

I worked with QNX 4 at uni and we built a robot system based on 2-4 networked 486/Pentium CPU cards in a rack with it [1]. We fully used the OS to make our robot system both hard real-time and completely network based using QNX's

AND no dust, grime, etc. These tiny wheels get dirty and clog up pretty fast in human environments and then stop to work and need a good cleaning. Nice for demos but unsuitable for even normal research lab work. I hate them.

Hmm, Kalkar, the only nuclear power plant I ever protested - in the late 70s when I was still in school and construction had just begun. It was finished in 85 but never even fueled due to safety concerns (liquid natrium is nasty, state gove

Erm, no, I don't think so. Can you give a source for that claim? Medieval wars were in general shorter, more regional, used much smaller forces and affected the civilian population less than in later ages. Of course it is very difficul

Athens-Sparta would be the Peloponnesian War, Punic wars were between Rome and Carthage. Sorry for the nitpick.

Interesting. I didn't notice the side notes at all because I immediately zoomed my view to only see the main text as I do with all web pages in this day and age.

To the contrary there is very good evidence that we pull arbitrary explanations whenever needed. See Gazzaniga's split brain experiments where people gave all sorts of reasons when asked why they did something and just could not know.

Since it is tidally locked around a low mass star, axial tilt should be near 0 and seasons should not exist [1]. Tidally locked also means much higher temperature than the estimated average (231K or -42C for the hotter one) on the sunny sid

C programming - luckily in my opinion - has a culture of very rigorous evaluation of programming techniques especially towards memory-unsafe programming, arguably the biggest weakness of C as a programming language. This book uses gets() wh

Backpropagation was probably the most important step, but there was also the issue of workable training methods for many-layer networks. Fukushima did some very important - but rarely mentioned - work about this starting in 1979. He trained

that's the way some embedded control systems are designed. with some (many) errors (can't read/write) being fatal and shutting down the system after an alarm is sent.

The programming language Occam, in its time the primary language to program Transputers, did not have operator precedence, so you had to use parentheses for anything. It was a huge pain, but probably still better than avoiding the edge case

Completely agree, except I'd say physical electronic instruments have a lifetime of about 20-30 years now. Several synths I own are now non- or half-working because of fading displays, broken floppy drives, power supplies and even chip

I worked in a big lab of about 100 engineer and scientists in the early 2000s. 2000-2005 more and more high-end SUN workstations were replaced by up-spec Linux machines. Only a handful of mostly CAD SUN workstations stayed. Main reasons wer

The Apple II was hardwired to run on 60Hz AC and used a limited character set. Minimal hardware design has its downsides. In countries that run 50Hz AC games and other real-time software ran slower or had wrong timing. I noticed quite a num

She gives very good advice for us non-designers though use color templates. They are available as book or webpage and by trying out just a handful that seem to fit your needs you can quickly get to a reasonably good design. It works for me

Well, for rooms with actual tatami mats, you are not really interested in the area, but rather how many mats will fit. Thus, a 24m^2 (12 mat) room with the wrong aspect ratio will not fit 12 mats. (I'm using the 1 mat = 2m^2 conversion

I think for Windows Mobile, their persistence and slowness made them fail. They kept trying to improve Windows CE based systems (not going to list all the renames) which were a very poor base to build on. When they finally decided to switch

Japan after ~1900 very much flip-flopped in their policy between playing the anti-imperialist liberator of Asia and its first colonial power and equal to western colonial powers for some time. Of course there was a political power struggle
