I'd love to see something like this but with jobs created.

New comment by actinium226 in "Ear Training Practice"

actinium226 — Fri, 12 Jun 2026 13:10:32 +0000

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.

This looks like they simply reinvented PID control. The inputs to the beyond are desired states minus actual states, which is basically how PID works.

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.

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.

Kind of funny that the people trusting AI too much appear to be the ones who will be left behind.

I have not had that experience, most of the time the duplicate question was answered, but to address the argument, it seems like it would be correct to mark a question as duplicate even if the original isn't answered. Why should there be two instances of the same question with no answer as opposed to one instance with no answer?

Boeing has the contract for SLS, not ULA. Boeing owns 50% of ULA, with Lockheed Martin owning the other 50%. But SLS is a Boeing product not a ULA one. ULA's main rocket now is the Vulcan, with a few more Atlas V launches left.

Does the market return 10% on average?

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?
