  • The question is always: What do you want to use it for?

    When raspberry started the landscape was very difficult. Small computer boards were expensive, now there’s the N100 if you need a tiny cheap computer. Microcontrollers were really dumb and unconnected, now there’s the ESP32 which has WiFi and Bluetooth and decent performance. Right in the middle of this wide spectrum is the raspberry pi and its clones.

    This is a very different situation than in the introduction era where PCs were heavy and expensive and microcontrollers were dumb. There was a much wider niche for the raspberry then. For a small server I would now get a $100 N100 from aliexpress. For embedded electronics I would grab a $10 ESP32. Only in the middle is the raspberry pi, but the problem is, it’s only in the middle in terms of performance, not price. A raspberry pi with case, PSU, storage etc costs more than a decked out N100, while actually being slower.

    The only remaining usecase I see for a pi 5 would be an electronics project where you need some more compute than a microcontroller can provide, like some machine vision project. Otherwise:

    • Do you want to make some electronics IoT thingy: Get an ESP32
    • Do you want a small light computer or server: Get an N100


  • 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.







  • I don’t think it will.

    Microsoft’s endgame is being the lord and master of AI. AI thrives on knowing more data about the user. What good is an assistant if it doesn’t know your habits, your wishes and desires, your schedule and your attitude towards each person in your life?

    This is not really a feature primarily aimed at helping the user directly (even though it’s currently marketed as such), but to have the AI build up a repository of knowledge about you. Which is hopefully used locally only. For now this seems to be the case, but knowing Microsoft, once they have established themselves as the leading product they will start monetising it in every way possible.

    Of course I’m very unhappy with this too. I’d like to have an AI assistant. But it has to be FOSS, and owned and operated by me. I don’t trust microsoft in any way. I’m already playing around with ollama, RAG scripting etc. It won’t be as good as simply signing up to OpenAI, Google or Microsoft but at least it will be mine.






  • 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.
