Hi, this is HN. It's perfectly reasonable to ask for sources. There isn't any need to be so hostile.

Depends on the context. The OP, IMO, was being passive-aggressive, almost incredulous.

As I said, every time anything comes up about Asahi, it is guaranteed that at least two threads will occur. This and comment about the vTuber. At this point - 2 years after the project began - it adds little value to the conversation, to the extent that the project lead, who was previously very active here, doesn’t contribute anymore.

In case of Marcan/Lina I got the impression that he created Lina just for fun. It started as an April fools joke (Lina 'took over' Marcan's live stream), but Marcan seems to enjoy it a lot, even going so far as contributing to the Inochi2D software (used to render Lina) to improve all sorts of facial features. I don't have the impression that in Marcan's case it was ever about anonymity, it is more about a creative e…

Isn't it the opposite, though? https://twitter.com/marcan42/status/1582930401118806016

I might be wrong here, but I have always been under the impression that they are the same person. I didn't even realise that is was supposed to be a secret.

Simple things like Lina en Marcan using the same hostname for the development machine (Raider), using the same IDE (Kate), using the same bash aliases (the one I like most if 'stfu' that appears to suppress terminal output), and a huge overlap of knowledge. Then there is also the same fast-paced speaking style that Marcan has.

I did notice Lina always (rather jokingly) denying being Marcan, especially during the April 1 debut, but I always assumed that that was just part of the joke.

Again, I might be wrong here, maybe they are not the same person after all, but as far as I can tell it's just Hector Martin having fun.

> Isn't it the opposite, though?

You mean Lina being first, and Marcan being an alter-ego? Marcan (Hector Martin) is a real person, he has done quite a few interviews on camera. https://youtu.be/dF2YQ92WKpM?t=496

The fact so much hardware these days is running a full real-time OS all the time annoys me. I know it is normal and understandable but everything is such a black box and it has already caused headaches (looking at you, Intel).

This isn't even that new of a thing. The floppy disk drive sold for the Commodore 64 included it's own 6502 CPU, ROM, and RAM. This ran its own disk operating system[1]. Clever programmers would upload their own code to the disk drive to get faster read/writes, pack data more densely on the disk, and even copy protection schemes that could validate the authenticity of a floppy. 1: https://en.wikipedia.org/wiki/Commod…

Yes, but ... Commodore did this because they had incompetent management. They shipped products (VIC-20, 1540) with hardware defect in one of the chips (6522), chip they manufactured themselves. The kicker is

- C64 shipped with 6526, a fixed version of 6522

- C64 is incompatible with 1540 anyway

They crippled C64 for no reason other than to sell more Commodore manufactured chips inside a pointless box. C128 was similar trick of stuffing C64 with garbage leftover from failed projects and selling computer with 2 CPUs and 2 graphic chips at twice the price. Before slow serial devices they were perfectly capable of making fast and cheaper to manufacture floppies for PET/CBM systems.

Thinkpad keyboards are great (I own a couple T400’s and used to daily drive a X61s), but the latest MacBook Pros have real, actually good keyboards afaik too.

I've tried them but they're nowhere near Lenovo quality sadly. Unfortunately Lenovo is on a downward trend with ever less travel with each generation so I guess they'll be on par in a few years :(

I can’t agree. I have a recent X series, and at this point, it’s approaching butterfly-keyboard levels of unreliability. I’ve always found the travel to be on the spongy side, but this iteration is terrible. Also, my trackpad literally has to warm up before it’s usable. I’ve tried with the track point, but it just doesn’t work for me.

And all that engineering resulted in a floppy drive that was slower and more expensive than comparable units for other home computers. I'm not sure if there is a lesson there...

Well, it was slower due to a hardware problem. Basically, the hardware serial device had a bug which required a bit bang comms channel to the disk drive. Doing that amidst the sometimes aggressive video DMA is what caused all the slowdowns. Back in the day I owned machines that did it both ways, but not a C64. My Atari computer also had a smart disk drive. Worked over something Atari called SIO, which is an early anc…

No, VIC-20/1540 had hardware problem. C64 shipped with fixed chips. C64 cant even work with 1540. Commodore crippled it because of incompetence.

What I like about Lina and Alyssa is the increase of visibility of LGBT+ people in the more "hardware" part of software development. As your get more low level, less visual and more niche, there's less and less diversity of software developers. And everyone should feel welcomed into hacking the kernel.

Everyone being welcomed into contributing to the kernel can result in a natural lack of diversity, as it selects for people interested in technical programming.

It is the ham-fisted attempts to increase diversity for its own sake have ended up being discriminatory. [1]

If there are barriers stopping people contributing, these should be removed. I expect these to be economic barriers, rather than those based on particular characteristics.

its a pretty amazing hack though the human body can scale from 1 cell to several trillion without going down for maintenance even once all while differentiating to different functions it can take a high level of damage and heal without needing a shutdown as well, most software crashes completely at the first exception cells give you that highly scalable and fault tolerant system that we all want

> without going down for maintenance even once doesn't it go down for maintenance approximately once a day?

It's more of a "sleep mode". There are still a lot of wakeups, and cron jobs running clean up of temporary files, cache management and backup routines. Background services still run.

I was shocked to read this comment because I interpreted your original comment as meaning a Philip K Dick novel would be optimistic compared to the cyberpunk dystopia in which we find ourselves now. lol Anyway it's pretty fair to confuse the two I think, there can't be any way Johnny Mnemonic wasn't influenced by Blade Runner (I'm guessing it's true of both the movies and of the books). Very similar themes and protag…

I’m watching The Peripheral, which seems to be influenced by Ready Player One. Which is ironical, since Gibson is a granddaddy of Ready Player One.

Half the comments here are talking about the vtuber herself. Who cares. It's been talked before. Just imagine if half the thread is discussing what gender she is. What I am interested in is the claims here https://asahilinux.org/2022/11/tales-of-the-m1-gpu/#rust-is-... . (what is it called if it comes with a proof?). The resident C/C++ experts here would have you believe that the same is possible in C/C++. Is that tr…

Except this is a blog post, not a Asahi Lina video … did you even click the link?
