  • Charles Bolden once remarked that the congress would have shut down the Apollo program if they lost vehicles at the rate spacex does now.

    Well, yes. But it was really a show of force towards the soviets and anything that could be construed as ‘failure’ would be sensitive. And it was all public money so things were very political and optics mattered. Society was also hugely different in the 60s.

    Also in the years before mercury a lot of stuff went boom, of course. Apollo was built upon those failures.

    I have a feeling that for SpaceX the opposite is true. Every time they shoot something up it’s press coverage, even if it blows up. As long as they’re not blowing up people they don’t get the boeing effect.

    Consider the first flight. They decided to launch it without a flame deflector or a deluge system. They thought that it would be OK based on a hot test of the superheavy at half thrust. I don’t think any other rocket company would have made the same decision. Even if the concrete slabs didn’t shatter into a thousand pieces, the reflected shock wave would have been damaging enough to the engine compartment. They predictably lifted off with several failed and failing engines.

    Yeah that was indeed very stupid. Agreed. Especially for the environment. They were right to get flak for that.

    If this afterthought feels like a conspiracy theory, remember the time when Musk made a change to starship after Tim Dodd (earlyastronaut) asked him a question on the same? Or the time when someone on Twitter asked Musk why they didn’t start two raptor engines and then shutoff the underperforming one during Starship’s flip maneuver at landing? They do this now. Afterthoughts are evidently not a rare thing at SpaceX.

    Could be yes… But don’t forget, it is their money. They’re clearly rushing to market and cutting corners, but as long as they don’t blow up people or property, it’s kinda their problem. And it has worked for them with Falcon 9.

    I do agree they are kinda cowboys but they do also have a point in some ways: Field testing is better than theory. I’d rather step into a rocket that has flown 30 times than one that has never flown before but a whole team of scientists think things will be fine.

    But yeah you still need theory and they could do a better job at that, I do agree there.







  • Oh it works great for me. In fact a lot better than the Rift did with its dedicated trackers.

    It’s also handy to just pop it on and not have to set it up. I often bring it to the office and I’ve given a demo for friends, it’s much harder with lighthouses.

    And the cost of them is just insane. If they were 100 bucks for a couple it’s fine.








  • Yeah that slogan really captured very well the intentions at the world economic forum.

    I know it’s not what they officially stated but it really captured (they since walked it back and said it only was meant to “describe emerging trends”) the intentions of what happens when they all come to Davos and divide the world between them.

    But I don’t believe “as a service” models are more sustainable. They will just enable more rent-seeking behaviour meaning we will get even less for our money. The incentive to deliver will be even lower as they will get paid anyhow.





  • Hmmm weird. I have a 4090 / Ryzen 5800X3D and 64GB and it runs really well. Admittedly it’s the 8B model because the intermediate sizes aren’t out yet and 70B simply won’t fly on a single GPU.

    But it really screams. Much faster than I can read. PS: Ollama is just llama.cpp under the hood.

    Edit: Ah, wait, I know what’s going wrong here. The 22B parameter model is probably too big for your VRAM. Then it gets extremely slow yes.
