Just posted the slides and audio recording from my session with @iamkale.millerti.me from #Identiverse 2026 which talked through some of the biggest misconceptions about #passkeys throughout 2025. blog.timcappalli.me/p/preso-idv26/

I'd probably cancel my Claude Pro if they remove Code from the $20 tier, I wasn't using it enough to run into limits and I can't see myself ever using it enough personally to upgrade to the Max 5x plan.

Simon Willison@simonwillison.net · 5mo ago

This is so confusing. Did Anthropic really just drop Claude Code from their $20/month plan? Why would they do that through a pricing page update without making a proper announcement? Plus, $20/month still gets you Cowork, which is really just Claude Code wearing a non-threatening hat!

Screenshot of the Claude pricing page - Claude Code is now listed for just Max 5x and Max 20x, but Claude Cowork is also listed for Pro

I had to make a "Politics" list and move some follows over to it because my Following timeline has not been good for my mental health. To the point my wife is concerned that I seem tired or depressed all the time...this also happened to me in 2017. Gotta dial it back like I had to back then too 🫠

Holy smokes, Affinity Photo, Designer, and Publisher are all now just a single app, and it's FREE? This is seriously great news, it might get me to switch back from Pixelmator Pro 🤔

Mike Hindle@mikehindle.uk · 11mo ago

Yessssssssssss! I had a sneaking feeling they may do this 🙌🏻 Affinity (now all three apps in one) is FREE 🤑 No restrictions, other than the AI tools (that nobody wants) only being available to Canva subscribers. www.affinity.studio #photography #art #design #illustration

The landing page for Affinity, showing it's now free of charge.

At Authenticate, @iamkale.millerti.me, @nishantkaushik.com, and I decided to mix up the usual "Passkeys 101" and cover common misconceptions about #passkeys. Topics around cloud sync, phishing resistance, workforce usage, and concerns about vendor lock in. blog.timcappalli.me/p/preso-auth...

The more I play with this, the more I love it. Even if I'm the only one using mlf.lol to generate #atproto lexicons, it has been worth it. It really hits the pleasure centers of my brain just right.

A screenshot of the mlf.lol playground, displaying an example of ATProto lexicon generation from a source MLF file. The MLF source uses inline types, def types, tokens, records, constraints, references, and references to a "standard library." Thematically, the source refers to posters on an old school forum.

RIFs can’t be done without agency leadership so this is RFK Jr extending his purge of CDC scientists to help Vought’s shutdown agenda. Genuine public health risks created by aggrieved men.

BREAKING: Friday night massacre underway at CDC. Doznes of "disease detectives," high-level scientists, entire Washington staff and editors of the MMWR (Morbidity and Mortality Weekly Report) have all been RIFed and received the following notice:

Cyberpsychosis is when too much cyber, but unlike the literalist “wow cool robot” depictions of cyborgs in media like the Cyberpunk™️ universe, what is really meant is being too enmeshed in networks of cybernetic feedback loops that cause a person to loose touch with the feedback of actual reality

Tony Stark@tonystark.bsky.social · 12mo ago

The fact that cyber/AI psychosis is becoming a regular talking point is the real turn towards the cyberpunk/Ex Supra timelines.
