asciilifeform: !#s ti-89

mircea_popescu: http://btcbase.org/log/2018-04-17#1800909 << wasn't, no. and yes, the ti-89, sure. or my ancient citizen solar powered item which i haven't seen for 15 years at the least but which was revolutionary for its time and literally worked by degrees -- if you obstructed two of its cell it could still slightly power the screen so it did. ☝︎

spyked: http://btcbase.org/log/2018-04-16#1799857 <-- which one(s)? ti-89? trying to get a better idea about how "os with clean no-assumption interface" looks. ☝︎

danielpbarron: apparently Euler argued that 0^0 should equal 1 on the basis that n^0 equals 1. also, my ti-89 says 0^0 = 1

BingoBoingo: ben_vulpes: With same language you can program the two best portable computers ever. The TI-89 and the TI-92

BingoBoingo: Also far more fun than real macs and the TI-89 because useful default software and full keyboard.

The fact that Mathematica, Sage, etc. also will not perform these simplifications without a 'hint' makes me feel a little better, but the question remains: How on earth did the TI engineers manage to do this with literally a tiny, tiny fraction of the computing power a desktop has?'

asciilifeform: 'In my own CAS development experience, I've found it nearly impossible to do what the TI-89 does, that is, automatically perform these simplifications without wrapping them in a 'hint' function. I've found that both in terms of computational cost, and in pure software engineering difficulty, this is basically impossible to do. Every CAS I've ever built has involved horrendous debugging of infinite recursion and similar bugs du

BingoBoingo spent two weeks of dishwashing checks on ti-89 senior year for the AP calc test

BingoBoingo: asciilifeform: No, I had the TI-89, mostly the same except for form factor. I have no idea what that important looking rectangle is.

asciilifeform: BingoBoingo had a ti-89 ?

BingoBoingo: asciilifeform: Palm V and I have great memories. My only regret is that PalmV and TI-89 never traded the best of their aspects

BingoBoingo: It was on the Ti-89 I had and the computer I acquired in the same window of time. My affinity is probably mostly through familiarity

danielpbarron: still got my ti-89; that was my favorite toy in school / used it in non-math classes instead of paying attention

BingoBoingo: asciilifeform: I tended to like it because in Highschool I had Hypercard, a giant TI-89, ot Compaq dos

BingoBoingo: Look, the way Bitcoin regulation works is my TI-89 was my favorite computer loving ass said the systemd war is over and initd won. Give it time to stew, but that's the fina word.

BingoBoingo: Azelphur: You mentioned the friend with a 486, if you've ever used a TI-89 you can convert him to saner options

BingoBoingo: Diablo-D3: My TI-89 met it's end in my usefulness when I realized the cheaper Mac Classic was basically the same thing.

BingoBoingo: asciilifeform: Well I was more imagining what it would take for a Rasberry Pi to truly be a TI-89 surrogate than imagining a project for myself in the near future.

BingoBoingo: When I fucked around on the old macs usually telling shit to wait worked. Never had a printer that was willing to cooperate though. Pretty much only had the change to touch screen, keyboard, and mouse... Also even faster TI-89

BingoBoingo: Before that though I banged away in motorola 68k assembler on the TI-89 and mac

BingoBoingo: mircea_popescu: At some point even a big head faile unless is surrenders to the aspersorzing. The TI-89 and the 0x0 Macs were the last machines I remember assembler and BASIC flavors being comparably organizable, though my experience in the matter is limited.

BingoBoingo: mircea_popescu: Probably, but it is quite a leap creating code that can be organized in assembly for the TI-89 and assembler for a modern x86 chip. I imagine the leap to the assembler OCL compile to would be still harder to organize.

BingoBoingo: asciilifeform: Well, I'd probably be limited to using the existing GCC port for the TI-89 to compile and hoping the NSA would let science the courtesy of having some decent sources for random and pseudo random numbers.

BingoBoingo: nubbins`: Maybe? After reading some of asciilifeform's blog though I took time to get reacquainted with my TI-89. It might be older hardware, but sometimes going for the Cougar is worth it... provided you remember the rubber and can afford the Valtrex.

nubbins`: BingoBoingo: So I'm thinking of getting a new offline computer and considering the Macintosh SE/30. It seems like a TI-89 on steroids. Any obvious faults I'm overlooking?
