  • The issue being that one is unlikely to gain the experience necessary to fully leverage the power of the tool, if it’s the primary way to code, because it does too much, to readily…

    How many CNC guys have the intuition of an of old school master machinist? Some do, most don’t. Plus, one of those masters can viably run many machines, with an unskilled observer monitoring to catch catastrophic fails. Fewer good jobs because of that. When automaton takes the learning out of the curve, very few people will put in the extra effort to grow beyond what’s needed for minimum viability, with all the knock on consequences that brings.

    LLM coding may not kill programming as we know it right now, but I think it’s just a matter of time, just like with US machining/manufacture. Once the learning track to mastery becomes unrewarded, very few will walk it.


  • I have a home-modified air popper that I use to roast coffee and I don’t get first crack if I put too much coffee in, turns out that the limit of my machine is about a quarter pound at a time, otherwise, I don’t get enough agitation for a fast, even roast. Maybe try reducing the amount of coffee you’re roasting?

    Another thing that can cause an issue for me is too long of an extension cord. I’m right about at what the limit of my machine can handle and the slight drop in current caused by the long cord is enough to lower the air temperature about 20 degrees.



  • Water that’s boiling is 100 degrees C, as long as you’re reasonably close to sea level. Boiling it longer doesn’t make it hotter. If you want super critical water, you need to microwave it in a very smooth container. Please be warned that this is incredibly dangerous as s.c. water can cause horrific burns as it will boil and overflow when you try to pour it. It also doesn’t make good coffee, it over extracts.






  • Do magnetic test, put a magnet to it, see if it sticks. If it passes the magnet test, then you know it’s either carbon steel or magnetic stainless. If it fails, you need to find something that is harder than aluminum, but softer than steel, like an actual piece of copper. Scratch someplace out of the way with the soft copper, if the metal is scratched by the copper, you know that the metal is softer than the copper, and that rules out stainless steel. The scratch test isn’t super reliable because some aluminum alloys are significantly harder than copper, but it’s better than nothing If you don’t have chemical tests available.

    Good luck in your search. The Italians used to make quite a few kitchen implements out of aluminum, so it is possible that it is aluminum. I have an old Bialetti Moka that is aluminum.






  • Seconding this. The difference between science and fooling around is just keeping a journal, writing things down.

    When I’m trying to hone in on my optimal experience with a particular bag of coffee, I’ll keep journal entries in this fashion: coffee name, date/time, grind setting on my burr grinder, coffee:water weight ratio in grams, starting water temperature, and time of pour; I’ll jot down a quick sentence after my first sip of how I feel about the taste, if I have time after finishing the cup I’ll jot down how I felt about the cup.

    I keep the journal (A6 size, spiral bound) and pen with my coffee making materials so it’s just part of the process, I think it may be adds 2 minutes tops, and being able to accurately repeat what I’ve done on a previous day without having to try to remember is totally worth it to me.
