Nine-minute run. My toes are frozen. 13 pull-ups.

- Emailed a friend.
- Went through public records to get the story on a house. (The owner from 1958 died two years ago after taking out a reverse mortgage, then her daughter got it and is selling it, possibly trying to cover what's left on the reverse mortgage.)
- Client B work.
- Condo communication, snow removal guy communication. (No way I'm shoveling 8-22" of snow on Saturday.)
- Verified that rsqrt is not the problem. The reason I was getting such different results between the two versions yesterday is that my test was flawed. My pd extension for logging only logged to something like seven significant digits. When I fed that into the C++ test harness for rsqrt, read the data from that log and so didn't get what was actually going into the pd rsqrt. After I fixed the pd block logging extension, the C++ rsqrt came up with almost exactly the same thing as the pd version.
- So now, the next problem is: what is the (significant) difference between what's coming into the rqsrt (added carrier fft results)? After a lot of shuffling things around in Google Sheets (still can't get MIN(FILTER(…)) working), I found out that the smallest value going into rqsrt on the pd is ~5.5e-9, which yields the largest result, 13229.70703. On the C++ side, the smallest input is ~3.9e-11, yielding 160226.875. Why do things get so much smaller on that side? Yet again, I do not know.

I don't actually go there, but it is indeed the only cheap grocery near those housing projects. That's a bummer.

Guess who has more energy to rally for a public golf course than people that would like to use that incredibly valuable land for something everyone could use? The problem with most governments is that there's so many things that are determined by a form of straw poll.

Probably a 35-minute run? My phone died, so I don't know when it ended, exactly. Also, I stepped in slush near the end, soaking my shoe, but it was not as miserable as expected. 12 pull-ups.

- Dropped off, picked up.
- Spent a lot of time reading Pure Data source; started to understand partly how overlap worked, though not fully.
- Took the guy to his social group, which seems to have gone well. He did some homework while we waited for it to start, and I did some thinking about Pure Data. While the session was going, I went out and got groceries. I was concerned about how much time driving out there was going to cost us, but a lot of it was salvageable.
- Searching for something that I didn't understand in the pd code lead me to the resynthesis example patch, which has a comment in it that explains that the overlapping happens on block intake as well as on output. That was enough for me to understand that my implementation in the C++ vocoder was completely wrong. (It was only making output blocks overlap after generating them, which in retrospect, is really problematic because it will make the whole thing shorter). I implemented it so that the samples it picks up each block will contain some samples from the previous block — overlapping, if you will. It's still not done, but it sounds much smoother now.
- Now the problem at hand is why the carrier signal doesn't come out as much. I found a bug (int instead of float) that made a rounding thing in my code never run. Fixing that made the result of an rsqrt on the carrier fft result much closer to the one that pd gets. However, maybe it's actually not? Because when it gets multiplied by another array the results are wildly different between the two versions. The next thing to do, which I might not be able to get to this week, is to examine the raw arrays involved in a spreadsheet.
- Went to the electronic music group. None us made much progress in the last week, but we chatted about fun things like album releases that are circuits and resolved to keep at it when we could.

Haha, this is great.

Neil Young posted a since-deleted letter to his management team and record label demanding that they remove his music from Spotify. “I am doing this because Spotify is spreading fake information about vaccines – potentially causing death to those who believe the disinformation being spread by them,” he wrote. “Please act on this immediately today and keep me informed of the time schedule.”

“I want you to let Spotify know immediately TODAY that I want all my music off their platform,” he continued. “They can have [Joe] Rogan or Young. Not both.” Young is referencing the steady stream of misinformation about vaccines that Joe Rogan has peddled on The Joe Rogan Experience. Last month, 270 doctors, physicians, and science educators signed an open letter asking Spotify to stop spreading Rogan’s baseless claims.

I hope this starts a trend among artists in that tier and adjacent ones.

It's always weird to me how every Deicide album is 100 times worse than Legion. If they had stopped after that, everyone would have assumed they were geniuses.

Conversely, bands that don't seem legendary can have amazing moments, and it's worth it for them to try for those. It's also probably better to have one great album and nine bad ones than ten decent-but-not-really-special albums.

The floor in our apartment is sloped in places. Weird finding: It's harder to maintain good posture while sitting on an office chair in the kitchen, where it's sloped, than it is in the living room, where it's flat.

- Kid D&D
- Condo communication.
- Client A work. Also sent a "how can we wrap up" email.

I accidentally took a nap after D&D and passed the "power nap" threshold of 20 minutes. I felt better for a little while, but overall, kinda wrecked me.
