Ben Eater's "Building an 8-bit computer" is a treat. He constructs a minimal computer from simple chips on breadboards, explaining everything. https://www.youtube.com/user/eaterbc/playlists

You can see Spacewar (and if you get into the demo room well before the demo starts, even play it) at the CHM in Mountain View, CA. The PDP-1 demo (with music synthesis and spacewar) is on first and third Saturdays, 2:30 and 3:15p [1]. But

In a well-known incident in 2016, Apple sued a company making fake "Apple" power adapters, and in the suit alleged that 90% of the "Apple" products on Amazon were fake. That such adapters are literally dangerous is clear

I'm amazed at how fast things moved in the computer industry. Per the article, FETs only just began to work in 1960, but by 1964 Seymour Cray at CDC was completing the 6600[1], a "supercomputer" with massive numbers of them.

Can't be arsed to follow this up, lacking links in the article. Does anyone know if there is a clue as to how the virus got into the country? It only circulates in very few places, I thought, and none in the Americas.

In Sir Terry Pratchett's novel _Making Money_ there is a hydraulic analog computer used to model the economy of Ankh-Morpork[1]. Sounds very much as if Pratchett might have heard of this Russian one. However according to that article,

No, interesting and useful. But a few questions. So basically you have automated the job of calling PyInstaller to make a standalone app, plus the step of wrapping the app in an installer. Yes? In order to use this, if I read the tutorial[1

With Python3 and PyQt5 it is literally as simple as "pip install pyqt5". I speak from having built and maintained multiple PyQt-based apps on MacOS. Edit: I should say, there are MacOS-unique difficulties if you want to bundle you
