I am a big fan of learning LISP, at least once. Going through SICP after more than a decade of writing code for a living was probably the single best thing I did to deepen my understanding of a lot of compsci concepts, data structures, and how to think about software. For me, at least, it was very much a seeing the matrix for the first time kind of moment. My LISP use has quickly declined, but I've dabbled in dozens of programming languages since then, and I do attribute not feeling lost to that experience.

Indeed, how exciting a phone would be that fit in... you know... bear with me... your pants' pocket you already have... lol

Indeed I have 3D assets in this case. Would this be done differently in an enterprise that has all kinds of tools to manage specialty workflows? Sure. Do I want to spend my days configuring and maintaining some binary blob / LFS storage system? No.

I’ve migrated a lot of projects from fossil to git eventually, but I dare say they never would have made it that far, had I started out with more friction, including fighting vcs tools.

I keep coming back to fossil again and again, despite git having a huge pull because of the easy publishing and collab on github/gitlab.

Just the other day I was starting an exploratory project, and thought: I'll just use git so I can throw this on github later. Well, silly me, it happened to contain some large binary files, and github rejected it, wanting me to use git-lfs for the big files. After half an hour of not getting it to work, I just thought screw it, I'll drop everything into fossil, and that was it. I have my issue tracker and wiki and everything, though admittedly I'll have some friction later on if I want to share this project. Not having to deal with random git-lfs errors later on when trying to merge commits with these large files is a plus, and if I ever want to, I can fast-export the repo and ingest it into git.

I was under the impression you could only activate one esim at a time, but store up to 6(?) on that phone?

This is probably a longer discussion, but PM0.3 (anything less than 0.3 microns) is quite difficult to measure, especially optically, as light scattering drops off very steeply once your particle sizes are around the wavelength of the light being used. Anything short of an SMPS class instrument that “grows” small particles through condensation so that they appear large enough to be counted, will not see much below 0.3 microns. Also, the total MASS of small particles might be low, but if you look at count, or lung-deposited surface area, we get a different picture. Especially around 0.3um, particulate matter is prone to get deep into the lungs, instead of being caught in the upper airways, and the small size means larger relative surface area, and thus higher reactivity. Even smaller nano particles might not go as deep, but are more likely to enter cells or the bloodstream due to their minuscule size.

While I admire the efforts of the SC-AQMD, and generally agree with the article, using R2 from a higher-end, but not quite perfect instrument, can be quite misleading, and is not a great indicator of actual sensor performance. Also, there are a lot of potential improvements in sensor tech, but instead almost everyone is relying on the same cheap sensor modules instead of innovating, which have have pretty bad deficiencies, especially in detecting particulates in the ultra-fine range, and don’t age very well. But, they are the cheapest.

... and I'm just sitting here wondering if the rims really are not round (as it's interlock the tire design seems to indeed indicate), and why on earth one would do that?

Interesting to note that the T2 chip in the new MBP supposedly contains the HD/Flash controller that used to be a separate IC -- according to the specs page. As it's a pretty fully featured SOC in its own right, that might make it easier to get to the HD in case of main CPU/RAM failures.

Back in ca 2001-2005 I used to work my summer nights for a tiny electric scooter rental place that had about 10-20 working scooters at a given time, renting them out to tourists at a lake, and they were fun, especially after learning how to tune the controller for a nice speed boost (for staff use only, of course). There were no serious accidents in all the time I worked there, even though the main customers were flip-flop wearing tourists and kids, driving these for the first time in crowded pedestrian areas.

For all intents and purposes, they worked and felt like the modern scooters, except that they had quick swap, fast charge AGM batteries. If we wanted to run an errand the next town over that would exceed a 30-40min ride (30min was a typical rental period), we'd just pack some extra batteries!

Those scooters were custom inventions, but larger scale commercialization never got anywhere and the business eventually died because of the battery tech being too cumbersome for consumer use, and the same legal questions that still plague us today, though it seems like electric bike usage the past 15 years has allowed at least some legislatures to give alternative powered transport a chance. As they should, as replacing large lumps of metal moving through our cities at unsafe speeds with much smaller lumps of metal moving a lot slower can only be a good thing for residents, pedestrians, and the environment.
