Those 1 page of notes allowed tests were very popular where I went to college. Common enough that most of those pages were 50% cutouts of older pages from the prerequisite courses that got optically zoomed or cropped on a photocopier. All the way down, until you get that one prof that insisted on handwritten notes. And there was always one nerd who tried to typeset his note sheet using tex or something, and spent much too long on it. Some of the tests allowed (additionally or alternatively) an usual unanotated maths reference book. Do people still do that? Funnily, once I got to grad school and actually used the book for something useful I started adding some notes, and had to buy a new one for some test.

wa27 posted:Just this week I dug out my TI-84 from 2005 and gave it to a 16 year old because their high school required a TI-84 and all the stores here were sold out. Looks like you can still sell them all day on ebay for $40. I mean good on TI for keeping a standard for school calculators, but at this point all the kids have Chromebooks. Surely there is a graphing web app or something that these could be replaced with. Desmos is good for this.

Explosionface posted:My mom broke out my dad's old calculator and asked if I wanted it, assuming I just wanted to throw it in the trash.  Handheld calculators in general are obsolete, but whenever I have to do any random one-off calculations I'm nowhere near as fast using a phone or computer as I used to be using a HP-15C.

Powered Descent posted:It was common for teachers to come around the room before a test so they could see the "Mem cleared" screen on everyone's TI-81. So of course, people wrote programs that would draw a fake of that screen. But that was less common than you'd think, since the program essentially had to draw the letters pixel by pixel (you couldn't just print it as text because it had lower-case letters). So in addition to being a huge pain to figure out and type in, the program also took up a good chunk of memory, not leaving much for your cheat sheets. So lot of us only did it once, just to prove we could outsmart the teacher, and then never bothered again. The current TI models now have a "test mode" that locks out that kind of stuff, and a very noticeable blinking light turns on so if you're walking around it is easy to see if test mode has been turned off.

SubG posted:I have somewhat more old RPN calculators than I need. I've posted this group shot in the thread before, but clockwise from the upper left it's a 11C, a 16C, the re-release of the 15C, and an original 15C. Nice! After a little bit of time working with the manual, I'm starting to like RPN. Anyone have any suggestions on how to clean my little guy up? Don't want to ruin any of the face, but the crusties all over are really bothering me.

Table calculators are doing well, thanks to the fact that it's always 100% easier and faster to use them instead of calc.exe.

Until you don't use it for a few days and it gets buried under a stack of paper. Finding it might be faster then calc.exe, but it is not faster then the table calculator emulator on my phone.

Like, Jordan Peterson is less slow than digging out your phone, unlocking it (which always takes 40 000 years), and opening the calculator app. Then it takes 40 000 000 years to press any key because you actually have to look at the thing since there's no actual keyboard for the calculator, with a home key. 3D Megadoodoo has a new favorite as of 10:33 on Apr 6, 2023 |

My phone is generally lying on the desk next to my mousepad while I am working. Probably on top of the stack of papers that has buried my desk calc. I suppose once you find your touch typing rhythm for your desk calc it becomes faster. But for me my touch typing is too used to a full sized pc numpad and I need to look down on the desk calc, too.

What does googling the serial number say? I can't really read it.

Well neither can I, that's why I asked. It's weird that it doesn't actually say what it is, because I've seen Intel logic analyzer thingies that look very similar, and say they're logic analyzer thingies (which is why I know they are).

Told the teacher the tv was on, he was all like "uhhhhh no its not" so I went over, hit the button, the screen flashed and went "power off" or something like that, and he seemed astounded that I knew it was on.

I learned from a Tom Scott video that young youtube viewers encountering that sound for the first time hate it whereas to us old farts it's merely the sound of having a TV on  . Maybe it sounds worse after a round of youtube compression.https://www.youtube.com/watch?v=RA5UiLYWdbM

Is that partly because, on average, most young people in general can hear a higher frequency range than older people? So it might part "old people like the sound, as far as they can remember what it was" but mostly "they literally can't hear the more annoying frequency." I even remember hearing stores of some places (maybe part of Japan?) using basically "dog whistles" to deter teenagers/youths from certain areas? Because most popel over like 30 couldn't' register the sound.

I can still hear that frequency, to me it doesn’t sound any different over a youtube video than in person. I have to imagine a large part of it is familiarity with the sound.

I think there's a different cultural context. Hearing that sound 30 years ago meant you were about to watch or play something so it was associated with something good while younger people these days have no association and are more likely to be hearing it over headphones so they get blasted by it and immediately think "wtf is that it hurts"

I'm generating some tones using Audacity as an impromptu hearing test, out of curiosity and terror. I tried a YouTube hearing test (for entertainment purposes only), and here's their scale: 8000hz (everyone) 12000hz (under 50) 15000hz (under 40) 16000hz (under 30) 17000hz (under 24) 18000hz (under 24) 19000hz (under 20) Now, I couldn't hear past 12000 on the YouTube video, but I got a nails-on-chalkboard response all the way up to 18000. 19000, nothing.

I think the tubes get noisier as they get older. I don't remember ever noticing it when I was a kid, but I've owned several terminals, monitors, and televisions which had pretty noticeable whines. I had an ADM3a from the late 70s with an absolutely horrendous whine (eyes watering after a minute or two, full-on headache after 10 minutes), but I've also got a B&W TV of a similar era that makes no whine at all. My VT220 makes a tiny bit of a whine but it's livable. No whine on the compact Macs or the Apple monitor on the Mac IIci. I don't remember any noise on the 1084S I had, but then I gave it away a couple years ago along with the Amigas.
