I tried this years ago to try to develop my ability to play by ear.

What I ended up learning is that if you want to learn to play by ear, learn to sing, don't bother with exercises like this, at least not until you've gotten some singing practice in.

When singing, you have to hear the intervals in your head before you sing them, so developing that ability to generate the intervals in your head will help you to recognize them later on.

I don't get how this is meaningfully different from doing something like:

1. Squash all your commits in this branch to one

2. Move that commit to the working directory with the appropriate git reset command

3. Commit hunks as appropriate.

VSCode is draining my battery, looking forward to trying this

Yea since writing this I think it has more to do with the regulator circuit. I plan to do a small rewrite and change the title to something like "When 3.3V isn't actually 3.3V" to more accurately reflect the situation. A decoupling cap would probably still help, but there were some mistakes made on the regulator circuit.

70 active on average at any given time per the article, which then lists total fleet size, as opposed to number of active cars on average, so it's not a fair comparison.

Although then it says they drive about 4m miles per week, which works out to 57,000 miles per active RA agent per week. A person driving ~25 mph on average 24/7 would do ~4000 miles in a week (and we can assume 24/7 here because they reported active agents, so we assume a team of ~3 people swapping out as driver in this hypothetical).

So that gives you a car/operator ratio of at least 14, and probably more since I bet the average speed is less than 25 mph.

But where are the AI features?? Gonna get left behind!

Only joking of course, actually quite refreshing to see a new version announcement of something this major without any AI nonsense.

OK, but what will they do next quarter? Loan out another 20 billion and get it back? And the quarter after that? Eventually you run out of people will to take loans from you to buy your chips and what do you think happens then?

I think you're looking too deeply at this. It's generally well written. I feel like you could take almost any sentence and say "look like AI" if you squint hard enough.

Regardless of it is was fully or partially written by AI, do you agree with the main points? Do you disagree?

Genuinely curious, what did you find painful about it? A while back I found it annoying that I'd get errors when cleaning out my branches because they were checked out in a worktree I'd forgotten about, but git now highlights branches checked out in worktrees and has done so for a while.

The books in the West in general kept getting less rigorous, with time.

I wonder if it's because more people are going to college who would have otherwise gone to a vocational or trade school? If the audience expands to include people who might not have studied calculus had they not chosen to go to college, I feel like textbooks have to change to accommodate that.

Generally that's what it means. And also when proofs are presented, a rigorous book will go through it fully, whereas a less rigorous one might just sketch out the main ideas of the proof and leave out some of the nitty gritty details (i.e. it's less rigorous to talk about "continuity" as "you can draw it without lifting the pen" as compared to the epsilon-delta definition, but epsilon-delta is pretty detailed and for intro calculus for non-mathematicians you don't really need it).

It doesn't look like they've made any drastic changes that would impel anyone to leave Arduino tomorrow, or in the foreseeable future, but if they keep going down this route I imagine the community will move to RPi. They've always been vastly more performant than Arduino and they can run linux, which is somewhat more approachable than the concept of programming a microcontroller and only being able to talk to it over serial.

Neat! I just sent out an order to JLCPCB for an ESP32 based board. I don't have a rework station or any experience with SMT so I decided to go for their assembly options. It's 80 per board, but would probably be cheaper per board if I got more than 2 (I also have more components on my board than you).

Question about the instructions in your README, you say that once you're done with the top side, repeat for the bottom, but when you're working on the bottom side, what stops the elements on the top side from falling off once the heat passes through the board and melts the solder on that side?
