"The need to be understood, to create things of value, to meet the inner lives of others, to refine one's emotions: these are everyday concerns. And they are played out - met or left unmet - as we go through our days trying to address our more obvious needs." John Armstrong

My wish for 2026 is that we move beyond pelicans and vibes-based oneshot web apps for model evaluations. Let them spend 2 hours implementing a detailed spec on a real-world project instead. In my testing, gpt-5.2-xhigh >> opus-4.5 >= gemini-3-pro-preview.

I talk to a lot of people who just use the "For you" timeline on X, and get baited into a permanent state of simmering rage by what they see there. The amount of time you should be spending on "For you" is ZERO - interact with X through curated lists and "Following" only.

A rather pretty form of military parade.
Don’t show Chinese drone shows to anyone from the Tri-State area, they may have an aneurysm.

Turns out WhatsApp does NOT have end-to-end encrypted backup enabled by default. Your backups are stored cleartext on cloud, which means the E2EE in chats are essentially a joke, if you backup. That's FB just being an ass and sneaky IMO.

Interesting talk worth watching about DAST at scale. MS basically went full circle between old solutions like parsing code to modifying built env to generate OpenAPI specs to feed DAST tools, to use AI to consume code & produce that. None works as expected at scale. What works?--
Take a rare look inside how Microsoft is working to use automated reverse engineering techniques to secure its own web services! youtube.com/watch?v=kfuOzDwv… #BlueHat

I’ve 40 times less followers on @bluesky but I don’t give a f*ck 🤷‍♂️ Why? - the moderation team is efficient - 3rd-party clients are welcome - there’s no ads - the mood is much better Unless you really want to show your support for Elon, give it a try!

Alright, time to give a try it. I'm also there, bsky.app/profile/rationalpsy…
Psst, if you don’t know, infosec people are finally switching to Bluesky. Matt Burgess put together a “starter pack” for infosec people (or just look at who I follow). I hope people start sharing their ideas and resources there bsky.app/profile/mattburgess…
