Any crypto you did couldn't be future-proof in the way it is today though. Don't know if that's mainly due to better algorithms or from the fact modern CPUs are optimized to rapidly decrypt/encrypt things.

It was algorithms. Back in the 90s there was no AES or ECC. There was RSA, and it was feasible to generate long keys, but it was impractical. Keys from back then could probably be easily factored nowadays. I think the spread of the Internet pushed demand for longer keys and better (more secure and efficient) algorithms.

Just because I was there (I agree with your general point) I wanted to say that I made my first PGP key in 1995 and it was a 4096 byte one, which is just as uncrackable now as it was then. I even remember being vaguely confused, because it gave you options, and I was thinking to myself "wut. Who wants the weaker-than-necessary key. I'll take the big one, thx"

Dynamic bitrate is the main one - the browser & server coordinate to figure out the highest video quality the user can watch without stuttering/buffering.

The client can do that 100% client side, you can serve pure static files with a JS player that handles the streaming. All you have to do is chunk the video into small 2-5 second chunks at a variety of nitrates and list them all in an .m3u8 playlist file if the right format. I know because I explored this for a hobby project of a movie I liked. See here: http://lelandbatey.com/projects/REDLINE-intro/ Use your network…

Pretty cool!

I'd like to know if they ever nearly died (or became very uncomfortable) from running out of food, broken boat, or otherwise. Their boat is very small and has only one engine, and it looks like they will sail thousands of kms in one leg on occasion. I am soft. If I must do this, and I would kick and scream, I would sell my house and buy a yacht with megalitres capacity of water, batteries, refrigerators, and starlink…

Somewhat unintuitively, smaller vessels have a strength advantage, assuming a well-made closed-top vessel... your main risk AIUI is getting dismasted in a capsize.

TL;DR is strength increases with square of the length, forces acting on the vessel increase with the cube of the length.

This guy is the champion of tiny blue-water vessels:

> That top comment is from John Nagle of Nagle's algorithm. I doubt his karma is from being negative. A relentless cynicism and the willingness to shoot down bad ideas are vital for producing anything worthwhile. Someone who was able to improve real-world networking is very likely to have been "negative" by modern standards.

I'm not sure I agree relentless cynicism is productive. Skepticism yes, that's very healthy.

But unchecked cynicism tends to result in a general lack of trust that is not very conducive to progress.

Site: "This website has no tracking or analytics." Privacy Badger blocked tracking from: googleads.g.doubleclick.net static.doubleclick.net play.google.com www.google.com www.youtube.com Because If you use anything from Google, you will be tracked.

It's an unfortunate use of Youtube embeds. Aside from letting people uncharitably dunk on them, the Youtube here isn't even doing anything. The YT video in question is https://www.youtube.com/watch?v=_1Y8PwD5XDs , which is 57s long, has 2 worthless comments, no description/metadata/playlist/closed-captions/categories, and a yt-dlp takes literally 5s for me to download the 1.5MB MP4. (Which I think may actually be about the size of the full weight of the YT embed container based on the last post I saw here whining about YT embeds...?)

This is a perfect candidate to host yourself and just slap it in some tags.

I'm somewhat surprised that this is your take on the project.

I agree with some of it in modified form, such as pointing out that far more powerful systems like old Android phones are sitting around in great quantity and would be a useful scavenge for a complete CollapseOS. In fact that seems to be what DuskOS is about, I'll be interested in your take on that once you have one.

But those are not microcontrollers, and what microcontrollers do can't be replaced by sticking a JTAG on an abandoned Android and calling it a day. Your take on the availability for scavenge of 6502s is simply incorrect, Western Digital, who should know, says annual production is in the hundreds of millions, joining the estimated 5 to 10 billion which already exist. https://www.westerndesigncenter.com/wdc/

It strikes me as a quixotic, but worthwhile, investment in civilizational insurance. I don't disagree about the motive at all, but it seems like a useful outlet for that sort of angst. If he keeps at it long enough I would hope he'll support a few more chips, and that seems likely, as I remember a time when it was Z80 only. Variants on that chip exist in their billions as well, although the original was taken off the market, hmm. This April.

Wow, you're the first person I've seen speak up about having similar experiences with them as me, thank you. I was a merveilles member some years back until I had some really rude/abusive interactions in IRC from Devine and a prominent moderator. I really would love to play with uxn and varvara but gosh I simply refuse to be around people like that.

i'm surprised to hear 6502s are being produced in quantity! thank you for the correction. any idea what they are used in? i've never found one ripping apart a tv, vcr, printer, dvd player, vacuum cleaner, power supply, radio, lab data recorder, washing machine, etc. i've found 8051 clones, 68000s, weird epson microcontrollers without a publicly documented instruction set, pals, z80 clones with dsp bolted on, and i've seen other people report pics and stm32s, but never a 6502 except in the drean brand commodore 64 i have here

looking on digikey i can't find any 6502 or 65c02 parts, although there are a couple of sbcs like https://www.digikey.com/en/products/detail/olimex-ltd/NEO650.... digikey of course doesn't have everything, but they're usually an okay indicator of what is popular

i agree that android phones cannot substitute for microcontrollers! their cortex-a cpus can't guarantee hard real-time responsiveness. and i agree with virgil's point that microcontrollers are very important for practical everyday things. and 6502s make perfectly good microcontrollers, albeit more power-hungry than designs fabbed in a smaller feature size, and requiring external memory

while the z80 itself is no longer made, plenty of clones of it are, and a z80 is also perfectly fine as a microcontroller, and a 6502 or z80 is close to the smallest machine on which a self-hosting development environment is feasible
