I (American) worked in Spain (Cáceres, Extremadura) ~2015-2017 in tech. It was a wonderful experience. Extremely talented, hard-working, and friendly co-workers. Great health-care and education systems. I think since then rising housing prices partially due to migration have become an issue, but it's a really, really nice place.

Adding

% !TEX program = lualatex

to the top of your document allows you to switch LaTeX engine. This is required for recent accessibility standards compliance (support for tagging and \DocumentMetadata). Compilation takes a bit longer though, but works fine, unlike with Overleaf where using the lualatex engine does not work in the free version.

Swap "solid rear axle" with "De Dion axle" and your description fits the Slate truck pretty well.

"one mushroom species in five is poisonous"? 20% ??? That seems like a crazy high estimate to me, at least if you mean deadly poisonous to humans. In the USA there are only a few species of amanita, galerina, a few of the hundreds of species of cortinarius, maybe some gyromitra and a handful of others I can think of that will kill you. Among the many thousands of mushroom species in the USA, there are only a few dozen known deadly poisonous ones. It's a really tiny percentage. Of course that doesn't mean that the others are edible, just not gonna kill you...

Very cool. I regularly plug logs with various spawn (lately hericium) and have had good luck covering the plug with natural clay instead of wax, which unfortunately I have tons of in my yard. In my case, the cover is mostly to prevent rodents from eating the mushroom spawn, which they seem to love.

I'm coming from an applied math perspective. A few of my favorites (and ones I find myself regularly referring to) are:

Matrix Analysis by Horn and Johnson (perhaps the best end-of-chapter problem sets of any math book I've encountered!)

Matrix Computations by Golub and Van Loan

Elements of Statistical Learning by Hastie, Friedman, Tibshirani

Functional Analysis by Reed and Simon

as others pointed out i misread the article, which says 2kwh per hour. indeed that is easily do-able.

My partner and I have been living "off grid" using PV + battery for electricity for the last 5 years in the Appalachian mountains. We track energy use meticulously. We try to use mostly wood heat in winter, but also have a buried propane tank for supplemental heat and hot water in winter. So that is arguably not fully off grid? We have a 2,400-sq. ft. A-frame house with R-52 insulation in most walls (closed-cell + batt) and low-e glass windows (but, alas, lots of windows). We mostly cook with electric or the woodstove in winter. Our woodstove is a massive, pretty efficient soapstone masonry stove central in the house by design. South-facing windows are backed by local stone floors that capture and radiate heat in winter. The house is angled to allow sun to enter windows in winter and block sun in summer for passive heating/cooling.

The two of us use just under 5kWh / day average electricity. Our big energy use is heat in winter though! Here is the breakdown:

5kWh/day electric * 365 days = 1825 kWh/year electrons

2.5 cords wood (mostly oak) = 17584 kWh/year wood heat

300 gal. liquid propane = 8400 kWh/year propane heat

That's a total of ~27800 kWh/year for the two of us including heat. That's about 76 kWh/day or 38 kWh/day per person on average. *This includes charging my e-bike for my work commute--but we also have a gas car so not nearly all transportation energy costs.[edited to add this]

I can't see any way to go much lower than that without freezing in the winter. 2 kWh/day seems crazy low to me.

Kersten led amazing research and MonetDB was really ground-breaking in many ways (columnar, shared memory interaction with client languages, etc.). A sad day.

Maybe? There exist some extreme-performance ARM CPUs like A64FX from Fujitsu.

Wow, this was almost my exact experience (except that I had somehow gone through life never using Windows). Using WSL is working out pretty well for me for the most part, except networking seems to break when the corporate VPN is on that I'm required to use (which is very irritating). I find myself prototyping things on my personal Linux laptop and only using the corporate machine for required company stuff. It's been an awful experience.

The current work

https://proceedings.mlsys.org/paper/2021/hash/3636638817772e...

seems mostly about tuning the original idea instead of expanding its scope. But it's still a neat idea. I guess it could be possible to adpt many of the approximations used in the SLIDE idea to GPUs too though...
