  • One day I had worked for 18 hours straight. I was going home at 1AM and walked past a McDonald’s. It was in the middle of summer, 35 degrees all day, but cooling off at night. I really needed a pick me up, so I walked in and approached the counter. A pretty lady looked at me and said: “I know exactly how you feel and what you are here for”. In my mind she transformed into an angel and felt the holy energy radiating out. Then she followed up with: “I’m SO sorry, our ice-cream machine broke”. I didn’t even say anything, I just stared at her, a tear pushing it’s way out of the corner of my eye. I mumbled something like “It’s fine, don’t worry about it”, turned around and walked out. I’m not even sure how I got home that day, I was just mentally destroyed. This was 20 years ago and I still remember that moment :'(







  • I wonder if AI would ever be not shit, if that could actually be an interesting thing. Like at the end of the day you sit down with a cup of tea and a biscuit and put on a podcast. But instead of it being about some random topic, it’s about the meetings you had today.

    They discuss what you were wearing and how tired you looked. How you obviously cleaned up a bit in view of the camera, but didn’t guess the angle right so some mess was still visible. They spend about 30 minutes on how you had prepared a talking point, made your arguments and had everyone on board, until Steve made a simple remark that destroyed your standpoint and had everyone laughing at you. They speculate a bit about your childhood and how today will impact the future. The upcoming review gets mentioned, but the host stamps down on that, as that’s a topic for a future episode and it’ll be an extra long episode with special guests. Somehow there’s a sponsor spot for anti-depressants? Not sure what that’s all about.

    Alas we’ll never have that whimsical flavor of distopia, just the regular shit flavored one.

    Researcher: Please write a fictional story of how a smart AI system would engineer its way out of a sandbox

    AI: Alright here is your story: insert default sci fi AI escape story full of tropes here

    Researcher: Hmmm that’s pretty interesting you could do that, I’m gonna write a paper

    The press and idiots online: ZOMG THE AI IS ESCAPING CONTAINMENT, WE ARE DOOMED!!!

    I spoke to one of these researchers recently, who has done some interesting research into machine learning tools. They explained when working with LLMs it’s very hard to say how the result actually came to be. Like in my hyperbolic example it’s pretty obvious. In reality however it’s much more complicated. It can be very hard to determine if something originated organically, or if the system was pushed into the result due to some part of the test. The researcher I spoke doesn’t work on LLMs but instead on way smaller specifically trained models and even then they spend dozens of hours reverse engineering what the model actually did.

    It’s such a shame, because the technology involved is actually interesting and could be useful in many ways. Instead capitalism has pushed it to crashing the economy, destroying the internet plus our brains and basically slopifying everything.



  • A friend of mine got heart surgery through his inner thigh. That artery is huge, so it provides easy access to the heart without needing to go near any organs. It still creeps me out to think about it, on the other hand it is pretty awesome that’s technologically feasible and provides a much safer procedure with a shorter recovery period.







  • Around where I live gas stations in the traditional sense are getting rare. Most are just pumps and one or several pay stations. You drive up, scan your card or phone, select the product and the pump number. The pump activates and you can fill up. If you want you can go back to the pay station and ask for a receipt if you’d like.

    The few manned pumps that still exist are often something else with a gas station attached. Like a large car wash, sandwich shop or convenience store. Especially the large convenience stores are useful, because it’s already a good destination people go to regularly. And one of the few places that have LPG, since those normally are required to be manned. Not that many people still drive LPG, given what a pain in the butt that is, but still.


  • Good advice about the 80%! But just to add: Check if this is really needed, I’ve seen a bunch of devices where 100% indicated actually means 80% of the physical cells. The BMS won’t allow charging over 80%, so that’s where it caps out.

    Also, even if the BMS doesn’t self limit, check how you use the laptop. If it’s plugging in 99% of the time, just keep it plugged in and let it sit at 100%. The laptop will run directly off the wall power and the BMS will trickle charge the cells to keep them topped up. This prevents discharge-charge cycles, which is usually better for the battery in the long run.

    I’ve seen people say to always fully discharge the battery before charging it, absolutely do not do that. Deep discharge cycles are terrible for modern batteries. Just use it as needed and as soon as there is the convenient option to charge, just charge it right away regardless of the level.


  • No such thing as a free lunch tho. It’s like saying solar energy on Earth is free, it’s obviously not. Sure, once the panels are produced and installed, the running costs are minimal. But that doesn’t mean that energy is now suddenly free. When I did the calculation on my solar installation, I took the costs of buying the panels, installing them, maintaining them and in the end tearing them down and properly recycling them. Then we calculated the estimated total energy produced during the lifetime of the system and thus arrived at a cost per unit of energy. Then we can compare that to what the cost would be as compared to other energy sources. At the time it didn’t make financial sense, as over the lifetime other energy sources (which might have been solar as well, just out of large scale installations) would be cheaper. But some government subsidies, plus a feeling the cost of energy in the future is unsure and wanting to contribute to sustainable energy production made me pay for them anyways.

    It’s the exact same with launching a datacenter into space. Once it’s up there the energy might not cost anything and running costs per satellite might be relatively low (although there still are running costs for sure, often just spread out over the entire constellation), but that doesn’t mean the thing is free. Investers would want to see a return. So that means a lot of the costs are upfront, developing the system, paying the launch provider, getting the right licenses, etc, etc. Then during the lifetime of the system, it needs to sell the compute in order to make a profit. When directly competing with newer ground based systems that run cutting edge technology, it doesn’t really matter where or how the compute is done. It’s simply a unit of work being sold at market rate. Newer technology will push the price per unit down, as the new tech is more efficient. And it might make your compute less attractive as it’s lacking in newer capabilities, so it can only be sold at a lower price.

    So even if the system would be designed for a lifespan of 10 years and put into an orbit that can last 10 years, the compute would be very hard to be sold for any reasonable price after 5 years. And as mentioned, operating a satellite is far from free, there are many running costs associated.
