I certainly got a lot of educational value out of mine. I managed to program a fully functional Minesweeper game on mine, using the built-in programming tools - no transferring efficient binaries via cable! But yes. 99% of what we did with them in class - when we were even allowed to use them - could have been handled by a little solar-powered calculator with basic arithmetic functions.

You could get that same educational value from programming things on a smartphone.

Current smartphones are highly optimized for content consumption a.k.a doom scrolling. Nothing serious exists for programming. On top of that, a touch keyboard and hard to reach special characters make programming on a modern smartphone a big chore. I miss the old days of smartphones that had a hardware keyboard with tactile feedback. I used to code up and maintain a PHP based dynamic website circa 2007 with a Sony Ericsson K770i and upload through a J2ME based FTP client that also had the text editor in it. If I remember it correctly it was called MobyExplorer

They had TI-85's in late '90s? I remember there only being TI-83s.

The order was: TI-81 (1990) TI-85 (1992) TI-82 (1993) TI-80 (1995) TI-92 (1995) TI-83 (1996) TI-86 (1996) TI-73 (1998) TI-83 Plus (1999) TI-89 (1998) TI-92 Plus (1998) TI-83 Plus Silver Edition (2001) TI-84 Plus (2004) TI-84 Plus Silver Edition (2004)

Anyone here have an idea why the models jumped around like that? Like why'd the 82 come out after the 85, or the 83 after the 92?

My TI-85 story. While I was in prison, around 1996 or 1997, I found out a friend had a TI-85 calculator. I realized it was programmable, so I borrowed it over the weekend and wrote a program to track his stock portfolio. It was the first time I had programmed anything in 2 or 3 years. Then I learned that the US Bureau of Prisons had a rule against any calculator (or device) that was "programmable". So I programmed th…

On 9 July 1537, Martin Luther wrote in a letter to Wolfgang Capito about a lost golden ring: "Pro annulo aureo gratias tibi agit mea Catharina, quam vix unquam magis indignatam vidi, quam ubi sensit, cum vel furto sublatum, vel sua negligentia (quod nec mihi verisimile est, licet usque ingerenti) amissum, quod persuaseram ei, hoc donum esse felix omen et augurium ei missum, tanquam nunc certum esset, vestram Ecclesia…

Are we expected to know latin, or is this supposed to be a little homework assignment for us? Ridiculous.

You're expected to use technology to break through the language barrier

Programming mine in high school is how I ended up coding for the first time and led to my current career. Honestly a pretty good investment (from my parents) I'd say.

Same for me, it was also my first time ever seeing code, and I still remember it well. While getting ready for swim practice in a locker room, my friend challenged me to beat his score on a button mashing game he programmed earlier that day in school on his TI-84. My 12 year old self was in awe of his BASIC skills.

It wasn't the first time I programmed but it was first time I encountered problem solving with code.

I'm not one those (very admirable) people who build just to build, who make their own version of frogger or something. I need a problem to solve.

But making a program that would take the parameters of a physics problem and spit out all the other quantities or that formatted output the way my stats teacher wanted it was a huge timesaver and that motivated me.

How does that help?

The ground pin, when "up", is higher than the hot, so in certain situations it can prevent something from shorting the hot and neutral. Code (?) or convention requires it if you have a metal faceplate, and hospitals require it. People generally like them mounted ground down because then they look like little faces. :-) edit: Not code, just convention.

Wouldn't it short hot and ground then, and still turn the necklace into a short-lived fuse?

The more practical reason to mount ground down is that wall warts with ground pins or polarized prongs nearly universally arrange them so that they're hanging down when inserted into a ground-down plug. If the plug's flipped, the wall wart's upside down and its weight is trying to lever it out of the wall.

Rather obviously these days one can copy/paste the Latin into google translate in mere seconds for relief ...

It's a beautiful device so much that hacker inside me wants to poke into what CPU they have and design a similar one in Verilog myself then put it on FPGA with similar display and it's driver then a 3D printed case and keys too.

If anybody here can illuminate where these names came from, I'd love to know!

Hahaha! This is great. Somewhat related. My mom once yelled at me for losing a necklace she really liked. Then we were moving her stuff out of her house and found the necklace behind a wardrobe, wedged between it and the wall. It had been there for like 40 years, layered in dust.

Yup, classic Martin Luther!
