  Totally justifiable IMO. In my day-to-day life its much more important that my shit works when I need it to than that I get whatever potentially something-breaking latest hotfix patch for everything on my system. Put simply: My OS, and the packages I use, work. If I don’t update, I’m sure it will also keep working. When I have time for an update to break something, or want to pull in some new feature or patch, I’ll run an update.

  The whole “maybe if the homework can be done by a machine then its not worth doing” thing is such a gross misunderstanding. Students need to learn how the simple things work in order to be able to learn the more complex things later on. If you want people that are capable of solving problems the machine can’t do, you first have to teach them the things the machine can in fact do.

  In practice, compute analytical derivatives or do mildly complicated addition by hand. We have automatic differentiation and computers for those things. But I having learned how to do those things has been absolutely critical for me to build the foundation I needed in order to be able to solve complex problems that an AI is far from being able to solve.

  While prat regenerates, it does so slowly, so they might actually have burned off some measurable elevation (on average)

  I just came back to Europe after a couple weeks in the US. The US was beautiful (travelled in the Rockies). I was surprised by the fact that I unironically would not be able to live there just because of the food. Everything was so drowned in cheese / sugar / unspecified ultraprocessed something that I had legitimate digestion issues the first week.

  • “I would like an omelette please”
  • “Yes sir, do you want eggs in that or just the cheese?”

  I had no idea I could miss just plain real bread as much as I did by the time I got back.

  Of course, Li-ion batteries will never cover large-scale power demand. Not primarily because of lack of lithium, but because it’s a technology that scales far too poorly into the MWh/TWh scale, and has a far too short lifetime.

  The battery tech we need for truly large scale storage is different from what we need for small, portable storage. Stuff like redox-flow batteries are looking promising.

  There’s also hydrogen, with different storage methods being actively researched- from direct storage to using ammonia as a carrier.

  The issue with using mechanical storage (like pumped hydropower) is threefold (off the top of my head):

  1. It has ridiculously low energy density
  2. Even after > 100 years of pumps and turbines, the power loss in a pump/release cycle is very high.
  3. It’s heavily limited by geography

  I’m not saying pumped hydropower isn’t part of the solution: I believe the solution is that we need many solutions. I just think it’s important to point out that battery tech isn’t some monolithic thing, and that there are issues with pumped hydropower (and mechanical storage in general).

  How in the world is (month/day/year) more sorted than (day/month/year)? I see two use-cases: Sorting things chronologically, in which case you want YYYY/MM/DD, or referring to nearby dates, where the year or even month can be assumed known implicitly, in which case you use DD/MM/YYYY. In no sane world does MM/DD/YYYY make sense.

  You could look up some videos on “mutation design” which is a stochastic design method, which is basically used to design structures (like drone bodies) by using random mutations. It really shows how evolution works in real time.

  Drake is fucked, because Kendrick has already dropped the Mr. Morale album, where he raps about his own shortcomings and relationship issues and how he’s worked to fix them. Whatever Drake says about him, it’s something he’s already been open about working to fix.

  Drake on the other hand is just dumbly denying that he’s done stuff everyone can see that he’s done, or just not addressing what Kendrick is saying at all.

• ⁨Comment⁩ on ⁨Hydrogen-powered planes almost ready for takeoff⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  If we’re able to make hydrocarbon-synthesis from CO2 efficient… we’re still going to need to source the hydrogen somewhere.

  But if we do that using electrolysis (with renewables), and are able to create more energy efficient CO2 capturing processes, I could see synthetic hydrocarbons as a viable fuel option in the future. The thing is: They’re stupidly good at being stable, energy dense, energy carriers. We also have a lot of infrastructure in place to handle hydrocarbons already.

  In principle, synthetic hydrocarbons could be part of a zero-emission cycle, where we capture CO2 and electrolyse hydrogen with renewable energy, and use the hydrocarbons as an energy carrier. But if we go that way, we’re definitely going to have to research efficient hydrogen production, and probably storage as well.

• ⁨Comment⁩ on ⁨Hydrogen-powered planes almost ready for takeoff⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  One of the advantages of hydrogen is that tanks and fuel cells can withstand a large number of “charging cycles” much better than batteries. Additionally, for ships, the amount of energy needed to move is so enormous that I fear we’ll have a hard time creating batteries that are feasible for long-distance shipping.

  For short distance ferrying (including large, car carrying ferries) on the other hand, Norway has already implemented quite a few electric stretches. The major issue there is building the infrastructure to charge the ferries.

  What surprises me is that if there is a zero-day flaw in a system used by the Norwegian government, why haven’t other entities been hacked? Is the system in question some system only used by the Norwegian government?
