i started building an alt firmware for the monome teletype (and grid) using claude code. it’s a sequencer based on markov chains

We are integrating with this. It’s very convenient (just send a header back)

Google Chrome is rolling out device-bound session credentials to all users. Session cookies get cryptographically tied to your device, so stolen cookies can't be replayed from a different machine. Attackers who exfiltrate your cookie database get nothing usable.

I wish @SlackHQ can ship this feature to move a channel message into a thread, then I'll delete "thread-please" emoji from our workspace

@rbbydotdev @matteocollina @nodejs @bunjavascript napi-rs is pretty much that, no?

Cool Runnings was good, finally watched it

I’m not watching Mortal Kombat II until screening in airplanes

[mark @andrus]

I wish this flight I’m about to get on had Mortal Kombat II

[mark @andrus]

Would I watch Mortal Kombat II on a flight? 100% yes above all else

@javierbyte They are also really into layered drinks, like drinks where there is a layer of foam or “cheese” on top (sometimes salty) that you drink through

Shanghai has all the experimental coffee flavors

[mark @andrus]

@javierbyte I had a plum americano, strawberry americano, this latte that looked like a fried egg — besides just flavors, the number of cafes is just incredibly dense

If you insist on fully visualizing every piece of math you learn, eventually visualization becomes the ceiling instead of the ladder.

@owickstrom Refresh rate is good? What monitor is this?

At this point, this is just irresponsible.

Yes, coding agents are leading to an increase of software production, but we are not seeing a similar push or increase in software quality.

If Anthropic focuses on safety and it believes software engineering is going away, then it needs to be doing much more to improve how we design, build, test, and maintain software (aka software engineering). Increasing the production of unreliable, poorly designed, and unverified software directly undermines safety.

Claude Code is claimed to be "fully written by AI". In the last two months, it took three separate postmortem-worthy failures and user complaints to surface what their own testing missed. Yesterday users were being over billed by hundreds of dollars. Software engineering isn't ready to go away and there is not enough progress to argue that case.

I am certain Anthropic would argue that AI progress in other domains is strongly dependent on having proper safeguards in place. I can't wrap my head around the cognitive dissonance when it comes to software.

PS: Mythos (may) improve software security, but that is only a subset of safety.

@roomcguire his head looks like it’s going to pop off

still playing RE9 but it’s sort of giving MGS4 vibes. there are some good mechanics and moments in RE9, but RE7 and RE8 felt fresh in comparison

ime there's always been a gap between industry code and the "beautiful" code you learn or write for a personal project… that gap is growing
