  • confirming that it is too difficult

    That statement bumps with the reality that is being built.

    It shouldn’t take a decade to write a conformant browser.

    I agree.

    A simpler specification would allow more projects to deliver compliant browsers.

    Also agree.

    Saying it was “started in 2019” without mentioning SerenityOS and the single person that was writing it all at the time is a bit disingenuous. It was just a single component within an entire OS that was also being written from the ground up (also entirely by one person). It was in 2022 that it was spun out into its own project because of the community interest in it.













  • I know who Scott Manley is. I’m subbed to his channel and saw that video when it came out.

    That being said, one of the top comments in that video is someone who, claims to be, a spacecraft thermal engineer. And they bring up a few good points. But the one I’m most interested in is the loss of efficiency in heat dissipation the further the heat is pushed along the array. Which means you can’t treat the entire surface area of the dissipation array at equal performance, so you need an even bigger array.

    And btw, a 20kw satellite is peanuts for AI workloads. Which is the reason they’re suggesting putting up a million of these. And that right there is, IMO, the biggest issue. We’re already at 14k satellites (most of those are Star Link). And 100k satellites is the current figure we expect collisions between satellites to start becoming unavoidable, with the possibility of an out of control cascade of collision becoming a major concern from there upwards.

    I think Kyle Hill did a better job at being objective on the problem:

  • So like you said, I’m correct. The only issue with thermal radiation is $/kg of payload.

    That’s not what you said. You implied the only limiting factor is a reasonable payload that can be resolved by the current incremental improvements to rocket tech.

    What I said is that even with massive improvements to rocket tech, it will still be a near impossibility to get as many AI (or even regular datacentre) satellites into space.

    The other issue is that the thermal dissipation problem is not solved for such a large amount of heat in space. It’s quite hard to dump large amounts of heat in space, and it needs to be done rapidly with computing. And the larger you make your dissipators the more you run into “how do I move that heat from the source and out towards the edge of the dissipators?” Because you need to utilize ALL of the dissipator if you want to keep your server parts cool. But moving that heat around a massive array is not trivial. If you’re using a fluid and moving it with pumps, then now your adding even more heat with the pumps.

    And then there’s the issue with long term investment. These server components are going to be obsolete in a few years (and nevermind failures). And IIRC, they have plans to regularly de-orbit these things every number of years, which means even more launches at a regular basis to keep the swarm numbers constant.

    And none of that matters in the face of the low earth orbit crowding issue that IS a massive problem.
