  • All that comes down to abstraction. Lots of stuff has been implemented in bare metal without making the distinction. Every DOS program was almost entirely bare metal except for loading it into memory and some disk I/O.

    Firmware is just a subtype of software.

    ROM doesn’t really exist anymore except on some legacy stuff. Certainly not on the ATmega series you were talking about. At most, these things have fuses that can be intentionally burned out after flashing so they can’t be overwitten later.





  • Needed to make two charge stops in the Chicago area. The first stop wasn’t too bad.

    Second stop was a disaster. Went to a dealership, but you had to go inside and ask the staff to turn it on, but they were closed on a Sunday. Went to a casino resort that supposedly had a charger, but they had moved it to the employee-only lot after offering it to the public for awhile. Went to a grocery store, and the app wouldn’t work. Went to another grocery store, and that one finally did it.

    Now, some of that is just bad charging infrastructure that can be fixed, but making two 30 minute stops on this journey isn’t ideal even if the chargers all worked properly. At 100 miles of range, you pretty much have to for this distance, and that’s only one way.

    At around 200 miles of range, I wouldn’t have needed any stops on the way there, but would on the way back. At 350 miles, I could have made it there and back no problem. I think that 350 mile number is the sweet spot. If you calculate off 20% for cold weather and 30% to stay within the ideal 10-80% charge range, then you can still get far enough that you ought to be taking a 30 minute break, anyway.












  • I do think minivans should be more common as being more practical, but I don’t see how they’re safer. They also tend to be less fuel efficient due to aerodynamics. They tend to have a lower floor with more or less the same ceiling height. That gives them a larger frontal cross section compared to an equivalent sized SUV.

    This applies to vans and trucks, as well. Trucks based on the same platform tend to have better mileage than the van.


  • It’s good to remind people that if they have a durable good that works fine, but its original manufacture was problematic, then it’s generally better to keep it as long as it’s doing its job. Even if the replacement is less problematic, it’s impossible to make anything without some kind of impact. Keeping durable goods going is better.

    Important for this thread is that cast iron, at least right now, is usually made in coal fired furnaces. It’s an incredibly dirty industry. Now, if I need a pan I will tend to prefer cast iron and then use it forever. But don’t throw stuff away that’s perfectly functional.
