The openness of those codecs depend on the last patent expiring, not the first.

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

It'd be nice to have some way to browse the pages without constantly hunting for the Next button.

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.

> wheel upgrade

At the same size (17"), going from steel to alloy improves performance but reduces durability. Larger wheels (20") are generally a downgrade for performance and ride quality.

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.

Natrium is expected to spend around 1 month refueling every 24 months.

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.

p1mrx — Sun, 19 Apr 2026 04:13:48 +0000

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 convince the code owners to accept it. Probably start with a standard analogous to RFC 5952?

> 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 to reply:

> I am standing on the ground. I feel 1G acceleration. My speed is not changing. How much am I accelerating?

You are accelerating at 1g through curved spacetime. Newtonian "speed" behaves strangely in curved spacetime.
