  • I studied electronics and GSM was a big part of the telecommunications subject. I visited the HQ of a mobile provider, was shown around and met the cartel boss (in hindsight, I wonder how much a Luigi moment would have affected the triopoly). I also visited a museum of technology and used an early touch-click model still connected to the network (pre-DTMF so not touch-tone, and no buffer so you had to wait for the simulated dial to stop clicking).

    But still, I don’t know the basics of wired phones cuz I’ve never really used them. How does voice travel both ways on a single twisted pair? How can Inspector Clouseau the telephone engineer in The Pink Panther (1978) hear a conversation from other phones in the house? How does the exchange know I’ve dialed the last digit? Can I use voice services on rotary phones, and what if I need to press * or #? All these would be obvious to 1980s kids…












  • Surprisingly many seem to be in real color: white, pink, red, orange, maybe brown, probably green, and yellow. (The well-known Neptune image is false color; Hubble deep-field is IR but that is redshifted so IDK, may be “real” color too.) Too bad white, pink and red are Earth’s atmospheric phenomena, of which only the aurora is really space-related, and green is just a satellite photo. Still, within NASA’s scope I guess.



  • On Slavic layouts, the right Alt key (AltGr) lets us type symbols like [, ], {, }, &, @, #, ×, ÷, , đ since 0-9 is for diacritical letters by default and numbers with Shift. Still, Czech Windows users mostly use Alt codes, which is a point of friction when switching to Linux. But there, I’m happy with how I can customize the AltGr and the new AltGr+Shift layers with curly quotes, em dash, nbsp, hair space, arrows, middle dot, pi (π), pretty pi (𝛑), mu, Omega etc. My Compose key is RCtrl.
