I almost can't believe this thing is on the Archive with ISOs and everything: archive.org/details/ldr_0496_6. This specific CD-ROM set is how I got started with Linux (Slackware 3.0 for the win). Back when FTP mirrors were things you shipped on CD-ROMs.

Hey! I'm waking up from my winter slumber and looking for / UI / product roles or projects. I love to work with kind people, move with intent and fix things.

I'm here for all parts of the process, from research to strategy, working with devs, or building design systems, incl. illustrations! And I know a lot about OS design as well thru coaching Prototype Fund teams at Superbloom.

Where? Remote/Berlin-based.

Boosts appreciated!

Nikolai Kardashev was a Soviet radio astronomer and astrophysicist who wanted to know how one could even detect extraterrestrial civilizations at all, the “SETI problem”.

He concluded: by energy consumption. The Kardashev scale is therefore not an ISO standard (ISO = Interstellar Standards Organization?), but a thinking tool devised by one person.

The scale says:

  • Type 1: Uses all the energy available to its planet. For example, an albedo-zero world completely covered in solar cells.
  • Type 2: Uses all the energy available to its star system. Not a million satellites in orbit, but a Dyson sphere that captures all the light and radiation of a star.
  • Type 3: Uses the energy of all stars in a galaxy.

The idea of launching data centers into space, more precisely into LEO, must therefore be evaluated on a different scale:

The Kardashian scale

  • A Type 1 civilization on the Kardashian scale has a public discourse that is no longer driven by facts, but by emotion and attention.
  • A Type 2 civilization no longer has this discourse under control, and counterfactual emotional discourse begins to control politics, research, and the economy, where unscientific and outright stupid narratives now take over steering.
  • A Type 3 civilization has complete epistemic decoupling: visibility has fully replaced truth, reach beats evidence, and consistency is irrelevant as long as the narrative is exciting. Physical limits are dismissed as “bad vibes”, and criticism is read as a moral flaw and subversion.

So we are not measuring energy, but loss of contact with reality. Many tech visions of recent years (everything from and including Bitcoin onward) map directly onto this scale.

We are now already a Kardashian Type 2 civilization.

Right now, Fediverse IDs resolve to HTTPS URLs.
For example, the Fediverse ID:

＠reiver＠mastodon.social

Resolves to HTTPS URL:

https;//mastodon·social/users/reiver

...

If we wanted cryptographic public-keys to serve as a basis of Identity on the Fediverse, then —

We would (similarly) also need a Fediverse ID to resolve to one or more cryptographic public-keys

...

@reiver ⊼ (Charles) :batman: (@reiver@mastodon.social)

Cryptographic public-keys are one way that one can have an identity (on the Fediverse, and elsewhere) while also having privacy — through a pseudonymous identity. Yes, we have Fediverse IDs such as: ＠joeblow＠example.com But a (non-delegated) public-key can function as a PORTABLE form of identity on the Fediverse. #ActivityPub #Cryptography #Fedidev #Fedidevs #Fediverse #JSONLD

RE: mastodon.social/@reiver/115945

The resolving of a Fediverse ID to one or more cryptographic public-keys could happen via the activity-file for the user.

A JSON-LD namespace (separate from ActivityPub) could put the cryptographic public-keys into the activity-file.

But, I think we would need more information than what the 2 current methods for including cryptographic public-keys currently support.

2026 심리상담 바우처 카드 신청했는데 이건 2주 후에 카드가 나온다고 해서 좀 기다려야하네요... 좀 오래 기다려야 해서 그동안에는 누구한테 상담을 할까 고민중이지만 주치의 선생님도 계시니까 엉뚱한 곳에 "으아아 내 인생 왜 이래 으아아아" 하지는 않을 것 같아요
