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…
You're a hero of mine so here is my story. Me in math class in 1996 - I had a TI-82 things are programmable so I have no formal education, my parents are illiterate, and taught myself to program, and I begged them to buy me one. I spent time learning how to code on it, writing from scratch, the game Spyhunter. I couldn't figure out how to draw with lines or pixels so I used ASCII or text. I presented this to my teach…

Since we’re sharing stories… In high school my stats teacher told us we had to get a proper calculator. She didn’t set any upper limit so i went down the calculators rabbit hole… and got an used ti-86 from 1999 off ebay for 35 euros (this was in 2007 or so). I programmed software to solve exercises in ti-basic and spent every lesson doing essentially software testing: basically whenever a classmate was called to the…
I had a 3D calculus class so I wrote a program in it to plot a 3D isometric mesh of a surface using the 2D rendering library. It was slow but got the job done. I used it to help pass a test or two.
I also experimented with drawing random surfaces and objects like a tire. They looked pretty cool for a calculator screen.
The math lab at the college had a cable which you could use to take data off or put it on so you could in theory have exchanged programs with others but this was before the internet so I didn't.
I still have mine and enjoy the sliding the cover off - a trip down memory lane.
Later I rewrote the program in QBasic on a PC for fun and it was lightning fast!
Re: Ti-84 Evo
#423About 25 years ago my parents got me a Ti84 as a surprise for Christmas and they hid it in the attic so I couldn't find it in the meantime. A few months went by and a couple days before Christmas, when it was time to wrap the presents they couldn't find it anymore. My dad went out and got a Casio something as a late minute replacement, and that was the calculator I used in high school and I never knew about this stor…

Seems like everyone has such a story about a teacher. „No you can’t read more advanced books because the current ones bore you“ etc etc What is the matter with these people.
What could go wrong?

Well, the TI-83/84 are called a graphing calculators for a reason: you can plot equations and datasets with them and look at them right there[1]. Looking at graphs is huge for learning, or at least it was for me, and school isn't just about plugging things in and getting an answer (or shouldn't be, at least). Doesn't mean it's not overpriced, but that's one reason and you can get a used TI-83/84 for like $30 or less.…
I mean a laptop running windows can use the old power toy calculator or something like speed crunch to do graphing and I'm sure Linux has countless others, with Chromebooks probably having more for free online as well, I can only assume.
Re: Ti-84 Evo
#427We had to buy those calculators for highschool and it was a waste of money, felt like somebody must be paying somebody off to have thousands of students buy a device that they will certainly never have to use (and is of little educational value).
But my wife is also a high school teacher and one of the most consistent problems I hear about from her is smartphones being a distraction. If she lets a kid use their smartphone as a calculator, odds are they'll soon be scrolling content feeds, playing games, or chatting with others. If her school required students to have a graphing calculator with limited functionality, it would probably be a benefit to her classroom.

They had TI-85's in late '90s? I remember there only being TI-83s.
They did! The TI-89 is how I aced the AP Math exam. The TI-92 had recently come out, and it had a QWERTY keyboard and could solve symbolic calculus problems like "find the derivative of 2x^3". This was a problem for the AP exam, since you could just type in the problem and get the answer. They fixed this by banning calculators with QWERTY keyboards. That's just about exactly when the TI-89 came out, which also did sy…
Spent some time on ticalc.org too, making some not-great stuff to get me thru those years
Re: Ti-84 Evo
#429Summary of the comments in here: * I used the programming functionality of the calculator to get around the rules * I didn't care much for the math, but my TI calculator was my first programming experience and it's what got me to love programming My experience is similar. We were allowed to use our TI-85s in class, but we had to go up to the teacher before the test and show him that we were running a factory reset, t…
Looking back on that experience, I’m very grateful to her, but she also probably didn’t realize I was programming it to also show the individual ‘steps’ to get the solution instead of just the solution.

It's typical. They're supposed have authority and be better than you. That is the purpose of their position and their identity. Don't be so quick to judge, because most people, including you would react the same way in similar contexts, for example if you were the top engineer at a company and someone started showing you up and being a hundred times better than you.
Not really? I've worked with people who were super productive with high quality work, and my reaction was to... gravitate toward working more with them. Some people are status driven. Some are not. Some are apparently pathologically status driven such that they'll compete with a literal child. In any case refusing to nurture such a child (even in effectively passive ways like letting them quietly do something more ad…
Now. That being said, the drive can be suppressed. But suppressing the drive doesn’t mean it doesn’t exist and that you don’t feel it. Also many people feel the drive at different levels of intensity that much is true.
Anecdotally your response to me indicates to me that you have not suppressed status seeking drives completely. The key hints are you’re referring to how you’re drawn to people who do high quality work. That is orthogonal to status seeking. Your status and identity is tied to a certain type of work you do and you take pride in. Have you worked with anyone who was so powerful that their work invalidated, crushed and basically humiliated anything you did. And let’s say this person is not malicious. He’s just so much better than you that your work and identity is inconsequential and eclipsed by his work.
If you said that you wouldn’t feel anything in the face of that then I would say that you truly do not seek status. I would also say you’re not human.
That being said a teacher holds his identity as someone who is better than children. He needs to be better than children in order to transfer his betterment (aka knowledge) to children. His role in society and identity rests on that foundation. If children are better then him and know more than him then that is inadvertently an attack on his identity. His reaction is natural and expected. It’s not that he has anything against the child, it’s self protection mechanisms to protect his identity via deluding himself. Very typical.
You see much of the same stuff with LLMs and programmers. A huge portion of HN was in denial for the longest time about the capabilities of LLMs calling these things stochastic parrots and thinking it’s impossible for the AI to take over. HN was just completely wrong about that and they were also wrong about driverless cars. The reason why they were so wrong is not because they’re making a logical and rational prediction… no they are choosing the prediction that most aligns with protecting their identity and skill set as programmers which is in the process of being replaced by agentic ai.
