Who reads this anyway? Nobody, that’s who. I could write just about anything here, and it wouldn’t make a difference. As a matter of fact, I’m kinda curious to find out how much text can you dump in here. If you’re like really verbose, you could go on and on about any pointless…[no more than this]

  • It gets even better when you read about annual or even daily energy production of a specific power plant.

    For example, the annual production of Aswan dam in Egypt is about 10 042 GWh, which translates to an average power output of about 1.1 GW. Now that you have this number, you can compare that with the maximum theoretical power output which is 2.1 GW. Therefore, they should have plenty of capacity left, but you can’t tell that just by looking at the published numbers. They just have to use convoluted units, because that’s the tradition in a bunch of industries.





  • That gives me an idea for a sci-fi weapon. It squeezes a few grams of stuff into an unstable black hole, which then releases all of the energy in a massive explosion.

    If there was a compression ray, it could cause a few pico grams of matter to form a black hole on the surface of the target. If you pulse it very quickly, you get the appearance of a continuous cutting beam. Obviously, those explosions would be very loud and they would emit lots of radiation, so maybe it could be a tank mounted weapon.






  • According to Microsoft, you can safely send your work related stuff to Copilot. Besides, most companies already use a lot of their software and cloud services, so LLM queries don’t really add very much. If you happen to be working for one of those companies, MS probably already knows what you do for a living, hosts your meeting notes, knows your calendar etc.

    If you’re working for Purism, RedHat or some other company like that, you might want to host your own LLM instead.






  • I’ve heard that brewing with super fresh grinds can be problematic due to excessive amounts of CO2 bubbles forming a layer between the solid and liquid phases. if that happens, you might mitigate that issue by extending the brewing time and and ensuring sufficient agitation. Probably not going to produce the ideal brew, but should be better than under extracted coffee.



  • Extracting with water should work better. You can heat up the water close to 100 °C to speed up the extraction. If you use milk, you can’t heat it up that much without running into all sorts of issues. If you use temperatures that are reasonable to milk (55-60 °C), those temperatures would be super low for extraction. That’s why milky drinks use water for making a highly concentrated coffee (espresso) and then mix it with milk.


  • I know someone who bought a bad batch of coffee. It was dirt cheap and tasted like water. You just had to compensate by using an obscene amount of grinds to produce a little bit of something that is almost drinkable.

    I’ve also bought some old coffee that was just barely within its shelf life. It tasted awful, but I guess you wouldn’t notice if you always use lots of creme and sugar. I drink my coffee black, so the only way to make it barely tolerable was to use 2-3x the normal dose and use an aeropress to make a super fast extraction. The longer the extraction takes, the more bad stuff will end up in the cup.


  • Should I start with the basics like grinding and extraction?

    I assume, those bags contain whole beans. If so, you need a grinder. You also need something like a V60 or an aeropress to handle the extraction and filtration. Oh, and using a scale is highly recommended, but not strictly necessary.

    If these things didn’t sound familiar, you’re in for a wild ride. This rabbit hole goes deep.
