The article mentions they’ll continue making the eZ80. If you’re in the middle of making a PCB around the Z80, you’ll just have to change the pins, I guess.

It is, but it probably shouldn’t be any more. WebP has good support everywhere now and is slightly better than JPEG and PNG combined. (Better lossy compression than JPEG, plus transparency support, and better lossless compression than PNG). But even WebP is considered lame these days compared to the new crop.

E.g., JXL (JPEG XL) is much better WebP and is supported by everyone except Google (which is ironic since Google helped create it). Google seems to want AVIF to be the winner for the new image format, but not many others do.

Anyway, until the Google JXL AVIF hissy fit is dealt with, at least we’ve still got WebP. It’s not super great, but it’s at least better than JPEG and PNG. A lot of web developers are stuck in their old JPEG PNG mindset and are being slow to adapt, so JPEG is still hanging around.

Out of curiosity, did you use it as a daily driver? A friend of mine tried it out briefly, and it was pretty cool, but the lack of applications meant we couldn’t really do anything with it (other than marvel at how cool it was). Did it eventually get applications developed for them? Like did they have an office suite?

I used to run a TFTP server on my router that held the decryption keys. As soon as a machine got far enough in the boot sequence to get network access, it would pull the decryption keys from the router. That way a thief would have to steal the router along with the computer, and have the router running when booting up the computer. It works wirelessly, too!

I mean…yeah. Just because something is provably the best possible thing, doesn’t mean it’s good. Sorting should be avoided if at all possible. (And in many cases, such as with numbers, you can do better than comparison-based sorts)

To the best of my knowledge, this “drives from the same batch fail at around the same time” folk wisdom has never been demonstrated in statistical studies. But, I mean, mixing drive models is certainly not going to do any harm.

Thank you!!

Subscribed! My daughter is super into beavers. Though I don’t want to get into a conversation about what “fucking” means yet, so maybe I’ll be selective which posts I show her.

The scary thing? Define “new”. This judgment is from a lawsuit in 2014. So any car made in at least the last 9 years is doing this. Maybe newer cars are doing even worse things.

Yup, mine, too. I don’t remember which version it was, but I’m pretty sure it was still “Turbo” (not “Borland”) Pascal, in the late 1990s. Grade 10 computer science was taught on Macintosh QuickBasic and then grades 11 and 12 were “real” programming in Turbo Pascal.

If you want a good CPU design with a 16-bit address space, take a look at the PDP-11.

Which was used in home computers, just not in the west

I agree with you, though. I’m kind of the prime market for this from an educational standpoint. My oldest kid has just learned to read and write (kind of). She’s fascinated by computers. She’s only played retrogames (happily) thus far, so she wouldn’t be put off by the 8-bit era’s graphics or sound.

But even so…what would I be hoping to teach her with this? How to work around the quirks of the 6502 that are not applicable to literally anything else? That life is full of unnecessary obstacles and frustration? That she could have learned more interesting programming in an easier way if I’d got her a computer with a flat memory model? I’m kind of meh on it.

You're not wrong, but there's a kind of irony in it when you talk about ending humanity because of it. There's a lot to hate about humanity if you have humanity and have human values. There's nothing objectively wrong about being cruel or destructive or dishonest or greedy or abusive or murderous and I imagine most hypothetical alien species would look at those things and say "what's wrong with any of that?"

But because humans evolved as social creatures and our survival depended upon trusting one another, we're constantly trying to judge ourselves against values that can't actually be met. So we look at ourselves and say we're a really horrible species, but that statement only makes sense because ironically we're a really glorious species that's fabricated these completely irrational things like love and compassion and empathy and honesty and sacrifice that no other species has (though many other social species do have bits and pieces of them).

And we'll forever hate ourselves for not being able to live up to our own values.

Not all of these issues have disappeared, either. Anyone remember this headline from a couple years ago? The bottom 1MiB of memory space on x86 is just a minefield. It’s impossible (like literally impossible) in general to know if certain parts of the address space are actual memory or are some weird part of your motherboard chipset or some other hardware. Windows I think still goes through the “wankery” of depending on chipset drivers to (accurately) know which parts of memory are actual memory.

Thankfully the 16-bit (though actually 20-bit but actually kind of more sometimes kind of but not totally) pains have all gone away. The move to flat 32-bit address spaces was a godsend.

RIP Bette Stephenson. In the same way that Al Gore invented the Internet, Bette Stephenson invented the ICON. She was a very stubborn politician who would not tolerate anything other than complete success from the project. Passed away 3 years ago.

I always coveted the Tandy 1000, but I never got one. Which one did you have?

The #1 defining moment for me has to be Second Reality by Future Crew. We got it an a local BBS not too long after it was released. It was kind of like the birth of a new era, like “ahh so this is what PCs are actually capable of”.

these games are guaranteed to not have any in-app purchases or ads

That’s a big plus. I also like that they have to use the keyboard, since the mouse can be a bit tricky when you’re young.

I had no idea there was a Richard Scarry game! They love the books, so maybe I should give it a shot. (Though it does look pretty mouse-heavy)

Another Oregan Trail generation here.

I’m curious about what’s going to happen with Gen Alpha. Any other moms and dads here exposing their kids to retrotech? I have two little ones that I’ve made a DOSBox installation for (Mixed-Up Mother Goose and Donald Duck’s Playground are their favourites). I do wonder how they’re going to think about old tech when they’re older. I haven’t told them that it’s “old” or “retro” yet, so they just think they’re normal fun games.

It’s a bit more complicated than that. Windows 95 used MSDOS to boot, but once it was booted, it completely removed any trace of MSDOS and replaced it with its own MSDOS subsystem. It’s more like MSDOS was a shell on top of Win95, but MSDOS was required to get the kernel loaded.

Yes, which is literally what OP is asking about. They mention system calls, and are asking, if a userland program can do dangerous thing using system calls, why is there a divide between user and kernel. “Because the kernel can then check permissions of the system call” is a great answer, but “hopefully you can’t harm your computer with userland programs” is completely wrong and misguided.
