HP calculators were great. I’ve owned several of the postfix based ones. (I.e. one enters 12, 30, + instead of 12 + 30) The article may not make it clear how many efforts were going on in that timeframe to manufacture calculators. The first

For my first few years programming I never used a statement of the form if ... else ... In late 1967, I taught myself to program. I never saw a computer during that time, but my high school owned a IBM 026 Keypunch machine used by the adm

It’s an older term; I’ve always liked it because of the imagery it invokes. It’s use dates back to at least 1528. The word terve used to mean turn upside down in English.

I'm not sure I understand it from the description that I read, but I believe the Zodiac cipher to be a pretty simple transposition cipher applied to a simple substitution cipher containing complications due to garbage phrases inserted

Breaking ciphers was one of my hobbies growing up the 60's. I wasn't particularly good at it, but I understood the methods used--I read everything I could find on the subject that was available in the open literature. See the bibl

I've programmed for a long time, since before the days of personal computers and graphical terminals (unless you count oscilloscope like vector graphics output devices). So, I'm quite comfortable at the command line and use it all

Yeah, Perl started out a bit like this. I never adopted it for myself or my company, but I did get a chance to have lunch with Larry Wall and talked to him about Perl. This was back when Perl was quite a young and promising language for a c

Smaller apertures in optical systems like the eye have a greater depth of field. This means that it is easier to focus when there is more light. As we get older the lenses in our eyes become less flexible and it is harder for our eyes to fo

It's very weird and spooky to dive at night like this. Ordinary night diving in relatively shallow water (say 10m) is challenging enough. It is easy to get very disoriented. The reward is seeing an entirely different world. I've s

> IIRC TX takes in ~$150b from the Federal government, but only pays ~$100b into the system. CA (like NY) pays more into the system then it takes out, so about ~$50b of the annual budget of TX is literally bumming money from other states

The title is a bit misleading. LaTeX is a macro package written using the TeX macro system, so I doubt that LaTeX itself is being rewritten in Rust. TeX, created by Donald Knuth, is now over 40 years old. It has a number of remarkable chara

I've had a few harrowing driving experiences and fortunately, no serious crashes. The difficult driving experiences where just so rare that I would be surprised if a self-driving vehicle would know what to do. * I once had a car drivin

Yes, I didn't explain myself very well. The second paragraph touches on my feelings about introducing "technology" into math education for kids. Generally, I see very little value of introducing tablets, laptops, or computers

I'm not an enthusiastic debugger. The problem with bugs is that while 99% are easy to spot with a printf or two, 1% of the bugs can be very hard to find. While coding, I will occasionally place an assertion at a place where a problem

There are a number of different ways to do this in Emacs, but org capture is probably the place to start. This feature is very powerful. See [1]. > That sounds kind of cool, though I’m not very familiar with emacs so it looks a bit str

Of course you are right, the slide rule works with logarithmic scales that are “added” together to do multiplication. Linear scales could be used to add, but the low number of significant digits (no more than three on standard slide rules)

Notice the domain name. I had no idea that there was such a TLD.

Generally, slide rules were only good for rough calculations (3 significant digits if you were lucky), but they did contain multiple scales providing multiplication, division, exponential, log10, ln, roots, sin, cos, tan, and hyperbolic tri

It wouldn't really be practical to use paper, compass, and straight edge to construct a slide rule. There are a great marks and they must be quite accurate. The are not spaced evenly; they are spaced logarithmically. To build a cardboa

I remember seeing a small exhibit of slide rules including some cylindrical ones at MIT in the early 70's. It was in a few display cases in one of the older buildings (I think it was building 1, but it could have been building 5--they
