Another Undead Computer Language

From Competitive Programming to APL, with Conor Hoekstra.

The first half or so of this article was like reading an anthropological report of a strange culture far away: There were no programming contests when I was getting started out in the field (1967-1976). I rarely had the kind of technical interviews that Hoekstra went through, and did not get any of the five programming jobs I held from 1977 to 1998 through such an interview.

I started reading more closely with

Conor: So, I heard about APL five different times between the year 2010 and 2019.

The Lifetimes of Programming Languages

I started programming computers in February of 1967, when I was a junior in high school. After dropping out of grad school I began a 41 year career in information technology in January of 1977. I have seen a lot of computer languages come and go. So I read 5 Programming Languages You Won’t Likely Be Using by 2030 with some interest. The only one on the list I had ever used was Perl. It was kind of fun, but I did not get very attached to it 🙂

Meanwhile, some much older languages live on. Last year COVID-19 demonstrated how much the financial world still depends on COBOL:

Blinking Astronomical Photographs

Low-Cost Approach to Scanning Historic Glass Plates Yields an Astronomical Surprise. Technical details at Precise Photometric Measurements from a 1903 Photographic Plate Using a Commercial Scanner.

Professional astrophotography used to be done on emulsion-coasted glass places. That was how astromical discoveries were made for nearly a century.

More than an estimated 2.4 million glass plates are out there in collections in North America alone. These were taken starting in the 1890s right up until the 1970s, when CCD (Charged Couple Device) detectors started to come online for astronomy. Of these, only an estimated 400,000 plates have been digitized to research quality

The team in this article has found a much cheaper way to proceed with this process, using off-the-shelf hardware.
