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 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.

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

When I was 10 or so, I "cracked" Slam! Air Hockey for Windows 3.1 by opening the exe in EDIT.COM and replacing some random binary garbage with spaces. After a few attempts, I managed to bypass the shareware dialog but also introduced some weird bugs that I don't recall the details of.

Human bodies are a trivial fraction of the fresh water on Earth. That makes about as much sense as stealing batteries to run the power grid.

If this is true, it's possible that the technology is from Nordic Nano. That would at least explain how a motor/software company could pull a battery out of thin air:

Their chief scientist is working on solar-powered hydrogen production, which seems fairly unrelated to solid state batteries:

Though TiO2 nanoparticles appear to be relevant to battery research in general:

Windows 11 isn't too bad after running Win11Debloat, but I get quite annoyed when an update shows "You're 100% there" for more than a second. 100% means done, why aren't you done yet?

When I was working on a deployment dashboard, I made it show ">0%" or "<100%" near the endpoints, to avoid misleading rounding.
