cout··on New study shows plants and animals emit a visible light that expires at death
I don't know about you, but I have trouble seeing other life forms in a room that is pitch black.
cout··on New study shows plants and animals emit a visible light that expires at death
It is surprising to me that it is in the visible range.
cout··on Kernel: Introduce Multikernel Architecture Support
I did not remember that from when I used to use colinux.

The colinux home page also says:

To cooperatively share hardware with the host operating system, coLinux does not access I/O devices directly. Instead, it interfaces with emulated devices provided by the coLinux drivers in the host OS. For example, a regular file in Windows can be used as a block device in coLinux. All real hardware interrupts are transparently forwarded to the host OS, so this way the host OS's control of the real hardware is not being disturbed and thus it continues to run smoothly.

So just like UML, colinux hooks int 80h (or sysenter) and forwards the request to windows. Thus while it may make use of direct access to the MMU, most devices iirc are virtualized.

cout··on Kernel: Introduce Multikernel Architecture Support
IIRC, colinux is similar to user mode Linux, which boots a kernel in userland. That is, the kernel runs under windows as an application rather than alongside it.
cout··on History of the Gem Desktop Environment
I wanted to like viewmax, but I think Digital Research was short-sighted. They intended it to compete with dosshell.exe, but the real competitor was windows. I was excited to get to play with GEM, but I had no way to write programs for it.
cout··on GNU Midnight Commander
The only time that is not after midnight is midnight.
cout··on I don't like curved displays
I had this experience back when the glass on CRTs was curved and monitors started shipping with knobs to adjust the curvature of the image. I had used a curved-glass CRT (curved the opposite way of today's curved monitors) for so long that nothing looked quite right after that until LCDs came into the picture (pun intended).
cout··on ChatGPT Developer Mode: Full MCP client access
Can you elaborate on what it means for a model to "lose its mind"? I tried what you suggested and the response seemed reasonable-ish, for an unreasonable question.
cout··on Shipping textures as PNGs is suboptimal
I have no idea how things are done today but in the opengl 1.x era multiple textures would sometimes be stored in a single image, so to get a different texture you would pick different texture coords.
cout··on The “impossibly small” Microdot web framework
Sounds like this framework is comparable in size to the original Rails, which clocked in at under 1000 lines of code (microdot is 765 lines per the article).

I don't know if the original Rails would have run on mruby though (if it had existed at the time), and Rails certainly did a lot of things the author of microdot would have considered "dark magic".

cout··on WiFi signals can measure heart rate
I don't remember that episode. But it does not surprise me that the Cardassians would build that feature into their station.
cout··on TPDE-LLVM: Faster LLVM -O0 Back-End
They do need to not be slow though, which is why I usually stick with -Og.
cout··on Microsoft BASIC for 6502 Microprocessor – Version 1.1
How do you write half a line of code?
cout··on A gentle introduction to CP/M
All I know about wordstar is 1) my dad used it on his kaypro luggable, and 2) I know the wordstar key commands from using Turbo C. How does wordstar compare to wordperfect 4.2 (which was my first hands-on experience with a word processor)?
cout··on Kazeta: An operating system that brings the console gaming experience of 90s
Is it still possible to buy smaller SD cards in bulk, maybe 8mb or 16mb? The smallest I could find was 128mb for about the same price as a 2gb card.

While I like the idea of physically separate cards for each game, at $10 per card it seems economically limiting.

cout··on The future of 32-bit support in the kernel
ELKS can still run on systems without an mmu (though not microcontrollers afaik).
cout··on No clicks, no content: The unsustainable future of AI search
I'm hoping the in the future there will be an LLM that can somehow map text back to its source. Current LLMs can kinda pull it off if you ask them, but afaik they aren't trained specially for this task.
cout··on It is worth it to buy the fast CPU
I've seen gcc+ld use a large amount of disk (dozens of GB) during LTO.
cout··on Optimizing our way through Metroid
Very impressive! I had wondered where that MB manip came from. No surprise at all that it was you. :)
cout··on Nitro: A tiny but flexible init system and process supervisor
What I got from looking at that comparison is that runit starts a separate supervisor process for each process started. I like the cleaner process tree of nitro, but I wonder what the tradeoffs are for each.
cout··on OpenAI Progress
The 404 links are truly bizarre. Nearly every link to github.com seems to be 404. That seems like something that should be trivial for a tool to verify.
cout··on Volkswagen locks horsepower behind paid subscription
When we think of computers Er think of solid state digital computers. But the first fuel injected vehicles were mechanical computers. I suspect it's still very possible to do the same today, but not practical to design.

Also I'm trying to think of what role the computer plays in emissions other than ensuring stoichiometry.

cout··on OpenBSD is so fast, I had to modify the program slightly to measure itself
Interesting. I tried to follow the discussion in the linked thread, and the only takeaway I got was "something to do with RCU". What id the simplified explanation?
cout··on Orion Browser
Why lynx and not w3m or links?
cout··on Keep Pydantic out of your Domain Layer
Having used sqlmodel recently for a project, I was underimpressed. Documentation was sparse, I found myself going to the source code to figure out how to solve problems I ran into, and I ended up dropping into sqlalchemy a lot more than I wanted. I think the idea is sound, but the code is hard to follow, and there are a lot of missing common cases.
cout··on Keep Pydantic out of your Domain Layer
Which existing framework is better?
cout··on Wii U SDBoot1 Exploit “paid the beak”
Even if you had the machine, it is not enough.

What was magical about that coding environment is that you could go to the store and pick up a computing magazine and type in a game. Then you could play it and tweak it as you wanted. I have no idea what the equivalent would be today; the cost analogue I can think of is watching Mario maker or Minecraft videos and then implementing what you learn in your own world or level.

cout··on A 14kb page can load much faster than a 15kb page (2022)
And a.out format often saves disk space over elf, despite duplicating code across executables.
cout··on Recovering from AI addiction
Yes, 4o can be quite wordy, but the voice chat model is much more brief. The voice chat model also is more than just text-to-speech; it correctly uses intonation to signify meaning.
cout··on Recovering from AI addiction
I saw that back in the day with icq. Two roommates in my dorm preferred to use text chat rather than engage in conversation.
