dear internet, i have a question for you

can you help me understand how it is, exactly, that if i plug a Transcend 512MB industrial compactflash card into my 286's XT-IDE, it works perfectly fine, with the exception that network cards - and seemingly only network cards - completely stop working?

it may help to know that this same model of compactflash card causes my 486 to refuse to boot and make a buzzing alarm noise that usually can only be produced by drastically overvolting the cpu

this is the machine i am usually referring to if i mention "my 486"

although strictly speaking it isn't always an actual 486 cpu, i also have a pentium overdrive and numerous cyrix parts that i swap in on occasion. it's a 100MHz Cyrix 5x86 right now

finally..... old computer....

@dalias@hachyderm.io there's a few things that do either that or something similar, sometimes under the term "cokernel"

the only thing vaguely like that which i've seen in real world embedded use is called xenomai, though i think it has two similar alternatives

@dalias@hachyderm.io on many RISC-V systems it's pretty easy to logically separate a core, some RAM, and some peripherals into its own domain to do this kind of thing, if you wanted to run, say, linux on cores 0 through 2 an zephyr on core 3 of an off the shelf 4-core RISC-V SBC, the majority of the changes would be in the device tree in order to set up that domain, and there would be hardware separation between them

i have seen similar done in some devices with ARM cores a bit more hackily with less/no hardware separation, with both Linux and NetBSD, but not in something production-ish

this post brought to you by a great deal of things, including the entirety of linux accessibility, tons of wayland stuff, sqlite on powerpc, so many things in firefox, and most recently, fakechroot

frequently, when investigating/debugging an interesting issue on a linux system, i find my good time interrupted by suddenly finding out that the issue i'm working was reported upstream years ago, has a working patch, the patch has been carried by several distros, the package does not and can work as intended without the patch, and the maintainers either have no interest in merging it or are entirely MIA

it makes me deeply unhappy, and it happens far too often

i've been sleeping on a giant beanbag chair in my closet this week and have realized that this is the sleeping arrangement i have been seeking all my life. screw beds. beanbag closet is my new bed.

i think a lot of people misuse closets

the obvious best way to use a closet is to take off the door, replace it with a curtain, and put the biggest fluffiest beanbag you can on the closet floor to fwump upon

@sima@chaos.social i once sort-of-interrupted a talk at an embedded conference (i was friendly with the talk-giver, and it was a pretty casual sort of event) to demonstrate with some live coding that it is actually completely reasonable to implement and use malloc() on a tightly constrained embedded device... as long as you don't need to implement free()

which, as it turns out, is frequently a valid strategy for a wide variety of embedded devices, either because they genuinely never need to free memory, or because if the need arises it is quicker and easier to just reset the chip

puppy has a full size human chair. two, actually,, one is in the basement and one is not. same model from ikea. we brought them with us in our recent move because they are his. he knows it. we know it.

if you are in one of his chairs and he wants to sit there, he will meow at you and you are expected to get up.

this is my cat, Puppy. if this boy doesn't think he's got it good i honestly don't know what else he'd want from me

@cinnamon@chitter.xyz i didnt name him that, we just kept the name

my mother in law is a veterinarian, he was brought in young for urinary issues and became the clinic cat for about 5 years, now he is ours. the original owners iirc were immigrants who spoke poor english and had named him "kitty". the clinic techs renamed him to "puppy" ostensibly as something temporary but it stuck

reading the news via the wii news channel restored with riiconnect24 is, certainly a way to keep up with the current events

wikipedia should have a list of things that are public domain in the united states because of the creator forgetting to put a copyright notice on it or register it with the us copyright office during the time period that was required

1. ancient unix source code
2. all dunkin donuts commercials before 1989

love that kind of hole in the wall restaurant that looks super rickety and run down and stuffed between two gas stations and the name of the place is "mike's" but its owned by a guy named muhammad, the beverage options are just a bunch of soda cans you have to grab from a fridge yourself, theres like three parking spaces

because you know you are getting some damn good food. if it werent good, it wouldnt still be standing

@mike@social.chinwag.org if you want to do it the most cursed way possible, install the PowerPC version of Windows NT on the iMac, install the x86 emulation subsystem onto that, and then download no$gba (which also does DS emulation)
