I recently got a pixel 3a for $83 on Amazon and loaded up CalyxOS. I swap sims back and forth and (re)register Signal on the device I’m using at the time. I also use MySudo on each for my burner numbers. Works well and I get to try out Android. I’ve had an iPhone since the 3g one I think, and was an active iOS developer since iOS 4. I can really say I like both systems.
Ahhh vi. I was reading the article hoping to see mention of vi…
Emacs was cool too, but I never got hooked - was very comfortable in vi land as it was the first editor I used on the old time terminals (green/amber CRT and a keyboard you could kill with). Oh the power of vi/EMACs and regular expressions without ever lifting a finger from the keyboard!
even a cheap exercise mat works well, I just can't stand sleeping on plastic though....
Ended up with a traditional mattress from the Original guys because we already had a matching bedroom set and my mate didn't want to drop $$ on a new setup...
Had a very expensive individual coil mattress for the last 7 years. This year started getting low back pain. Talked to these guys: http://www.originalmattress.com . No gimmicks, just straight dope on how a mattress should work and why theirs do and many others fail. Also it's a local "factory to buyer" direct set - up so there's no phony sales and markups.
I also use a body pillow to put in-between my knees (I've been using a body pillow for most of my adult life) and that sure helps keep my body aligned.
Good luck!
P.S.
Ever try chiropractic? Might not be for everyone, but I swap services with a local chiro - sure helps me out when I tweak my back snowboarding/skateboarding....
