@Austen Notifications I’d pay for: “There’s a handwash only ceramic thing in here so I stopped” “Don’t put that in. These are clean.” “Cool if I run for +10min? A few of these still need work” “TV show is on a really quiet scene and felt like I was being loud so I paused for a sec”
@Austen Home appliances have been stalled in product innovation plateau for decades. Attempts to claw out of it are looking more desperate than interesting.
@MartySmithESPN @Lane_Kiffin This is will be a historic interview for sports journalism. That’s the look of a guy overtaken with fear of the true consequences of what he just did.
@SmithMitchP @MartySmithESPN @PeteThamel @Lane_Kiffin And kinda threw his family under the bus. If it’s not about the money, was the “family decision” because they hate Oxford?
@Austen Cult following budding behind this thing called StackOverflow
@CtrlAltIdeate @Austen You just need to market it as 2 brands solving different problems - vibe code security audit or claude adoption enforcer - depending on where the org is in their AI ops commitment journey.
Less bullish on AGI timelines today after asking 3 frontier reasoning models to convert an .svg to lottie.

@kurtfunai their discord has a ton of really cool applications of it
@ppearlesscentt It was beautiful but nothing compared to Carrie Coon’s monologue in the finale of @TheLeftoversHBO . That one will tear apart your soul.
Check out what we've been working on: hackerone.com/product/code
PullRequest is now @Hacker0x01 Code 🎉 We started @pullrequestcom in 2017 to fight the compounding impact of bad code with AI + human expertise. Today that cost is ~$2.4T led by cybercrime losses, software supply chain problems & tech debt. Very excited for our next chapter.
Watching MCP gain momentum reminds me of early API adoption—huge potential but massive risk if you’re not careful. @Hacker0x01 bug bounty programs and AI red teaming aren’t nice-to-haves anymore. They bring in external perspectives, which is what you need when your system opens to the external world.
Proving ROI for "shift left" security is based on a doomed premise: cost savings by avoiding unexpected losses. Business value is return on mitigation + cost efficiencies of fixing it pre-prod. And do it right. Understand developers and how they work. hackerone.com/blog/cost-savi…
@CruciformLig @melissa I read it as the motive, willingness as the combined question and answer
