I distinctly remember iPhone being AT&T exclusive. So I guess this is how I learned Cingular was purchased by AT&T

It was the IBM 1620 model 1 that had in-memory lookup tables for arithmetic: bitsavers.org/pdf/ibm/1620.... Its codename was CADET, and there was a joke that it stood for "Can't Add, Doesn't Even Try".

IBM 1401 had actual arithmetic circuits: www.righto.com/2015/10/qui-...

I know IBM's System/360 had an 8-bit byte, I kind of thought that popularized it. I'm now wondering how long other sizes lasted and what killed them off.

How would demos of CD-ROM DOS games have been distributed?

I vaguely remember playing Peter Pan: A Story Painting Adventure on DOS as a kid. Looking it up, it seems like it came on CD-ROM. But there was also a demo of it, I wonder how that demo... was distributed?

Just made yet another personal project where I just used plain DOM manipulation.

It's starting to get tedious.

But then I'd have to look at frameworks and frameworks with their build processes always feel like overkill.

What retronetworking networks exist? I know of HNET built on IBM's NJE running on TCP/IP, and vaguely of HECNET (some DEC thing that I know even less about)

Feeling nostalgic for Magnatune

I'm wondering about characters intended for legacy computing documentation that aren't in that block. At least group mark (U+2BD2) was specifically added for that purpose.

(I have some interest in that specifically due to recently messing with IBM 1401 emulators)

I don't know much about Warhammer but thought it was a physical only game. Is there a digital version or were you playing in person then switched to digital game at midnight?

Now I'm interested in learning about these :/

I have a CD-R next to two CD-ROMs from my childhood. I half suspect that that CD-R contains more stuff from my childhood, but Windows 11 acted like it was blank. Guess I should try a VM

I loved the Power Rangers as a kid, and I loved edutainment games, but never heard of this. I'll have to seek it out.

Have been trying to learn about abstract math stuff lately (set theory, inaccessible cardinals, ordinal arithmetic), and it's all stuff that is incredibly fascinating but I don't see a "real world" use (outside of it being interesting, which is certainly a good enough reason to learn something)

Donald Trump must fire Kristi Noem immediately.

Or Democrats will initiate impeachment proceedings against her in the House.

We can do this the easy way or the hard way.

It's weird to see people yelling at Senator Schumer to do something when he announces that he is, in fact, doing something.

Chewable ADHD medicine would have been a godsend for me as a kid.

Instead, I chewed non-chewable Ritalin and chewed gum to get the horrid taste out of my mouth.

I finally figured out how the Android back button works.

When you press back, it flips a coin to decide whether to take you back or go to something unrelated.

I don't know if anyone still uses Snapchat.

I still have it installed, but it's the only social media I've had to block notifications on.

I was a Dilbert fanatic when I was a kid (not the target audience). Read and owned several of the books, had Dilbert's Desktop Games, watched Dilbert VRML cartoons.

I think I might vaguely remember having a more text-y Dilbert book, so maybe it was The Dilbert Future

Did The Dilbert Future have comic strips?

I distinctly remember that affirmations stuff and my guilt that I didn't teach my mom about it before she died of cancer.

But I don't think I bought any Dilbert books that weren't comic strip compilations. I might be misremembering that though.

rather than talk about Scott Adams I want to talk about something weirder (me). Who else was really into Dilbert when you were 12. Who else was like, boy, I can't wait to work a cubicle job

Did you get Dilbert's Desktop Games? I brought that into show and tell as a kid but was a bit awkward because I thought it was violent.

It's unusual for a wellness grifter to claim vitamins don't exist, isn't it?

Any idea where I can read about NASA computing history from the 50s? I'm curious about the General Mills AD/ECS-37 machine and the most I've seen is a fragment of assembly

I loved that game as a kid. Broke my heart when I heard that Bill Nye was embarrassed by it.

I wasn't aware there were Eyewitness books. As a kid I had the Eyewitness Encyclopedia of Space and the Universe software, I liked the planetarium.
