A solar array makes the earth less reflective by a fixed amount, for as long as the array exists. Every unit of fossil fuel we burn makes the earth permanently less reflective (or at least something on the order of 100 years). You could co

Even if you ignore my LLM numbers, "what percent of a reactor's output must be reinvested to enrich its own fuel?" is a meaningful contribution to the discussion.

Take these numbers with a grain of salt because I got them by chatting with AIs, but if you're producing electricity from HALEU, then centrifuges require reinvesting <1% of the output, whereas historical calutrons required 200% (use

Gravity is not "harvested", it just stores the energy briefly. Someone or something has to lift the weight for every shot, which requires energy. It's not obvious whether a trebuchet is better than compressed air, like a BB g

My favorite '90s weather app was WetSock. The installer was 1.5MB, though I don't recall the RAM usage. It showed a sunny/cloudy/etc. icon in the system tray, with the temperature in a tooltip: https://web.a

Note that MPEG-4 part 2 is H.263/DivX/XviD, not H.264.

That sounds less janky than my solution: US wall wart charger -> 6ft extension cord -> international adapter. (If you want to overvolt an extension cord, make sure it's completely passive: no light, switch, or surge protector.)

They're collecting 10X more data, at roughly the same energy per collision.

TP-Link hardware is decent, if you buy one with OpenWrt support.

You can escape Switzerland by going straight up into space. It's only "in" the EU in 2 dimensions, maybe 2.5 since you can't dig your way out.

Sodium (without chlorine or similar) is a metal, not a salt. They plan to use molten salt for energy storage, but the reactor itself is liquid metal cooled.

I think it's a reasonable decision. The only people who will interact with dav2d by name are codec nerds, and a simple increment makes the lineage more obvious to that audience.

I tried to make an orchestra where they smash household objects, and a synthpop song where all the lyrics are burped. Didn't work. Wake me up when we're in the future for real.

It would be pretty straightforward to change the text selection rule, so that double-clicking anything matching the syntax of an IPv6 address selects the whole address. The hard part is to find all the places to repeat that change, and conv

> the only case where a newer version of software comes back closer to an older one Winamp 3 -> Winamp 5 was closer to Winamp 2. Windows 8 -> Windows 10 was closer to Windows 7. Though I don't expect this to happen with IP.

https://en.wikipedia.org/wiki/UTF-7 exists, but was rarely used. UTF-8 is convenient because ASCII has a spare bit, but UTF-8 is fundamentally possible because ASCII is variable-length. IPv4 is not variable-length.

According to general relativity, you (and the ground) are accelerating at 1g, and feel weight because your inertia resists that acceleration. If you jump off a cliff, you'll stop accelerating for a bit, until the ground hits you. Edit

What if they use heat pumps to raise the temperature? Heat rejection is proportional to T^4.
