I think you're reading in something that isn't there. I do want lazy banks to fail. Banks that want to capture a fat spread based on vapid affinity marketing (e.g. so called "Community Banks") that offer no credit beyond what Big4 banks already provide, with none of the rigor & accountability.

i keep being impressed by how incredibly broken passkeys are. the passkeys are in my vault, the vault is unlocked, its for the right browser, has the right extension, but if the website cant access those for whatever reason, youre just stuck with no way to progress and locked out of your account

so why did you install vscode? go use a regular text editor then. GNU Nano is less than 500 kb.

that seems fine? it's an electron app, so full chromium runtime. which allows you to share a browser tab with copilot, click on an DOM element and say 'fix it'. I just checked Obsidian and it's also about 300 MB on disk.

On trial for causing FOMO? Making teens fear missing out is one of the accusations states have hurled at Meta in a case going to trial this week. I did an explainer of sorts @reason.com reason.com/2026/08/12/a...

Another social media 'addiction' trial starts today. Its claims are weak—but dangerous
Meta is on trial for fomenting "FOMO," among other things. It sounds silly, but the playbook used here could work against religious groups, fast food, and much more.

then again, this whole debacle was created by the 'double-opt-in' standard, I think this standard is silly for an open data protocol and you should just autobridge people that reply to a fedi account. replying is autoconsenting to be bridged, full stop, forward all complaints to /dev/null

yeah, it's not spam, it's helpful. the bsky dms are not part of the protocol anyway, so as long as the bsky team is okay with it, it's fine. anyone building on atprotocol is free to implement their own DM solution that would preclude such messages.

Enshittification Still Matters
Decentralized social infrastructure is not a sidequest to DeFi. It is essential for protecting online identities and relationships from the inevitable enshittification of centralized platforms.

I built a vocabulary game where after learning a new word, you have to use it on social media to prove you actually learned it. It works on Farcaster and X so far, and I’m thinking about bringing it to bluesky next. Wonder if people here would like that type of game?

The cryptographers on this app will talk about how awesome RCS is because it is standards-based E2EE without acknowledging that the underlying standards are a recipe for centralizing the operators. We need a different way forward.

I think I get why the US environmental movement went so wrong. It's really hard to get people to support local solutions to global problems, the only way is to ally with dumb reactionaries. But if your movement is full of dumb reactionaries, after a while your solutions will be reactionary and dumb

Public health education did that more than sin taxes is my argument. OTOH, cigarette taxes directly killed Eric Garner, these policies are not violence free.

I agree! More access to gambling will increase gambling issues. More access to alcohol will increase alcohol issues. That being said, unless you have a plan to shut down the internet, prohibition on prediction markets is even more farcial than alcohol prohibition. The solution is education.

Gambling regulations' primary effect has been to line the pockets of those who can lobby the state to get casino licenses, its effect on curtailing problem gambling is marginal to nil. Classic example of Bootleggers and Baptists.

I know it's difficult but you gotta channel the deepest, most intense neurodivergent hyperfixation into the subject. Then haters will bounce off you for the same reason 'video games are for nerds' was pure background noise to the kids who were trying to take their consoles apart to see how they work

Qualified Reservations
An XKCD-style webcomic featuring a horizontal line with several stick figures representing different decentralized social protocols, labeled from left to right in order of increasing "purity."
​The title at the top reads: "PROTOCOLS ARRANGED BY PURITY" with an arrow pointing right labeled "MORE PURE."
​From left to right, the protocols and their accompanying dialogue are:
​ActivityPub: A stick figure stands at the start of the line.
​ATProto: A figure with glasses says, "ActivityPub is just federated ATProto."
​DSNP: A figure holding a small octopus says, "ATProto is just federated DSNP."
​Farcaster: A figure holding a bubbling flask says, "DSNP is just Polkadot-parachain Farcaster."
​Nostr: A figure looking back toward the others says, "Which still requires BFT consensus. It's nice to be on top."
​Urbit: Located far to the right, separated by a large gap, a figure waves and says, "Oh, Hey, I didn't see you guys all the way over there."
​The comic satirizes the "purity testing" and elitism within decentralized tech communities, ending with Urbit positioned as the most extreme and isolated outlier.

Can I run @pds.ls to browse a dev-env PDS? I can see a list of dids on the localhost PDS, but I can't actually inspect any of them, because then I just get "missing PDS", no did document exists presumably, but I should be able to just skip that part and see the data anyway.

sufficiently decentralized
A satirical medieval‑style cartoon showing two opposing factions. On the left, banners labeled with phrases like ‘Our Blessed DID:PLC’ and names such as Swiss Shellco, ATScan Mirror, PLC BFT POA, and Bluesky PBC appear on castles and ships. On the right, an opposing group labeled ‘Their Barbarous Snapchain’ features Delaware C Corp, Quilibrium Fork, Tendermint POA, and Neynar, Inc. The scene exaggerates the rivalry between two tech ecosystems by depicting them as warring kingdoms.
