  • There’s some sort of electrolytic process similar to aluminium available, but yes the reaction that turns iron ore into iron is:

    Iron oxide + carbon monoxide + heat ->

    A redox reaction where oxygen atoms are transferred from iron oxide to carbon monoxide ->

    Iron + CO2.

    Heat and CO is conveniently provided by burning coal/coke in a blast furnace in the presence of a lot of oxygen.

    You can pretty much just chuck layers of coke and iron ore in the top of your blast furnace, pump high pressure oxygen into the centre, and get molten iron straight out the bottom.


  • Now if you turn anything off (like that stupid autobrake that brakes for cars in the left hand turn lane beside me), they’ll use that to say “it’s not our fault, the driver turned it off!”

    Don’t try and spin this as a convenient liability-limiter for manufacturers.

    Unless it is an actual failure of a safety critical system, with no warning, that then directly leads to harm, manufacturers are in no way responsible for how you operate the chunk of metal and technology that you bought from them.

    All this stuff absolutely helps to reduce the overall risk of injury when operating a vehicle. Is it also a pain in the ass sometimes? Sure it is. Can you turn it off? Sure you can. But sometimes that shutoff is just temporary, because governments - not manufacturers - mandate that some things are now required, because they’re sick of hosing body parts off of highways.



  • The article is quite fixated on how dialup was around in the early 2000s, and how Americans used dialup in the early 2000s with screeching modems, and how AOL turned off their dialup last year and only a thousand people were using dialup by then.

    But there’s no indication that this has anything to do with the application, except for maybe everyone used a popular means to connect to the Internet to use it when it was first built.

    Now if someone maintained a bank of modems and people legitimately called them up and connected to the system like it was an ISP, and it was secure by way of that was the only way to access it as opposed to over the Internet, then sure, I can see that maybe it’s time to work on that part.







  • Well, from a technical standpoint they now routinely do weekly what was never ever done before by anyone. Both in launch cadence of their booster fleet and the recovery of them, and they’ve pretty much fully transitioned to only making their Stage 2’s and just using their existing fleet of boosters. So from a rocket company perspective, SpaceX is a legitimate company, and they’ve made legitimate advances in the field of rocketry, and now they outpace the rest of the global market combined in tons to orbit.

    Then you fold in Starlink, which needs those weekly launches to maintain the constellation… and then you fold in Starship, which is the next generation launch platform, and it’s like “Ok… that’s still rocket-y, that’s cool”.

    And then along comes xAI tacked onto the side like a 100 billion dollar dead weight and that is where things get a bit wobbly.
