We often call “dropdown” any list of vertical options. But there are a lot of different options on how to build those. Vitaly Friedman gives some great form UX tips by to help you understand the difference, and when to use which. The goal is really to be consistent when talking with the people on your project.

in terms of hosting, yes, there's some nuance re: how much your hosting is happy to store vs what you're putting there. i think this is mostly a problem for videos (json is fine) but definitely something i'm curious to see how it'll evolve

(지역 상관없이) 청년들의 극우화는 이런 영향이 더 큰 것 같기도 노력하면 좋은 직장 얻고 잘 살 수 있다고 세뇌당하다시피 했는데 막상 성인이 돼서 취업전선에 내몰리니 본인들이 생각해온 노력의 보상인 직장 문턱은 너무나 좁은 반면 옆에서 사회적 약자들이 각종 혜택을 받는 걸 보면 그 사람들은 노력 없이 그런 보상을 받아가는 것처럼 보여서 속이 뒤틀리는 거겠지 그래서 계속 공정! 공정한 경쟁! 이라고 외치는 거고

We're helping people in Iran get set up with .

So far we've supported several servers (directly and indirectly) so the community has infrastructure nobody can just switch off.
Right now we're preparing for the next internet shutdown. Offline plans and local comms aren't nice-to-haves they're literally survival tools.
We prepare before the blackout, not after.

With hope for in Iran.

CIA to Sunset the World Factbook

Link: abc.net.au/news/2026-02-05/cia
Discussion: news.ycombinator.com/item?id=4

CIA says it will cease publishing the CIA World Factbook

A statement on the CIA's website gives no reason for the decision, simply stating that the Factbook has been "sunset" while encouraging readers to "stay curious about the world and find ways to explore it".

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.

RE: mastodon.social/@reiver/115945

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.
