I think one of the reasons for this is to have very high throughput charging stations in dense urban areas (like central Beijing).

> "we have to cater to what 96% of users know" Indeed. Just recently saw a talk "Are we stuck with the same Desktop UX forever? | Ubuntu Summit 25.10" (https://www.youtube.com/watch?v=1fZTOjd_bOQ) where Scott Jenson (Apple/Google UX) laments we stopped innovating on Desktop.

Such appeal to conformity is indeed quite sad from GNOME.

Jonathan McDowell keeps track of all the Starlink Sat orbits, including failures:

Don't confuse launch _price_ with launch _cost_. It's been estimated the internal F9 launch costs are around $15M-$20M.

The $5M is a marginal cost-target for fully reusable Starship.

Well, divide et impera. Fairly straightforward for AI inference (not training): The existing Starlink constellation:

3491 V1 sats × 22.68 m² = 79176 m²

5856 V2-mini sats × 104.96 m² = 614 646 m²

Total: 0.7 km² of PERC Mono cells with 23% efficiency.

At around 313W/m² we get 217MW. But half the orbit it's in shade, so only ~100MW.

The planned Starship-launched V2 constellation (40k V3 sats, 256.94 m²) comes out at 10 km², ~1.5GW.

So it's not like these ideas are "out there".

Ideally, in an organization this should be a centrally pushed group policy defining CIDRs.

Like, at home, I have 10/8 and public IPv6 addresses.

Yeah, I had to create a user on many language versions just to keep the old skin. I fail to see a point in wasting 2/3 of my screen estate to whitespace.

Having a 60 days consultation with the Fish and Wildlife Service whether a falling hot-stage ring (essentially dumb steel piece) causes danger to fish is just silly.

Not the first case - It was Kodak who built the first digital camera after all.

NTR is a very inefficient use of nuclear fuel. What you want is a NSWR: https://en.wikipedia.org/wiki/Nuclear_salt-water_rocket

A true nuclear rocket. Just like a chemical rocket is a controlled explosion, NSWR is a controlled (cough) nuclear explosion.

Sun wanted to do the same thing in late 90ties - picoJAVA (embedded), microJava and UltraJava (VLIW workstations).

Relegated to the dustbin of history.

It can be - the allocator just needs to mmap() different bucket pools to different base addresses.
