I used a 3.3 µF, 370V_AC capacitor in a previous Villard Circuit voltage doubler, but I used 67 nF capacitors in a Greinacher Circuit voltage doubler.

That’s a huge capacitance difference. Did I do the Greinacher Circuit correctly?

The SHELL: A Global Tool for Calling and Chaining Procedures in the System
Louis Pouzin
April 2, 1965

Most modern operating systems include a “shell” of one form or another, sometimes text-based, sometimes graphical. The first shell was written by Louis Pouzin. It dates to 1963 or 1964. He even wrote a paper about it.

A long time ago, I worked at a company that has since merged with another large company. Back in the day, my employers kept a technical reference library that included back issues of a magazine, Software: Experience and Practice. A few of the earliest issues of that magazine had a “Computer Recreations” column. Volume 2, pages 397-400 had a column on self reproducing programs.

Another quote attributed to Harry Millner that appears in a few places:

Early Permian terrestrial apex predator regurgitalite indicates opportunistic feeding behaviour by Arnaud Rebillard, Andréas Jannel, Lorenzo Marchetti Mark J. MacDougall, Christopher Hamann, J.-Sébastien Steyer & Jörg Fröbisch

A fascinating paper in many ways!

I bought a 8-port Netgear GS308E switch. I plugged it in, and it worked, but I noticed the LEDs on the RJ-11 ethernet socket flickered regularly.

Appears to have originally been published in UK by Natural History Museum, London.

I came across an article by Brian Kernighan. The article is about a piece of C code written by Rob Pike, apparently for a book Pike and Kernighan wrote together, The Practice of Programming.
