One cool thing about designing your vibe coding workflow for verifiability and testability is that you can switch out models and only impact performance, including switching to local models

Would the rust build scripts with some conditionals give you the experience you want? You still cargo build

go.sum Is Not a Lockfile In Go, go.mod acts as both manifest and lockfile. There is never a reason to look at go.sum.

PSA: go.sum is not a lockfile.

You never need to look at go.sum.

go.mod has everything you need.

Of course itโ€™s not perfect since we can still (I guess) verify the code ourselves

One fun simile of AI producing a lot of math/code and produced proofs of correctness using formal verification is that itโ€™s like weโ€™re moving to an NP feeling era where the statements are math/code and witnesses are these proofs

Thoughts on what tools and protocols we have at our disposal for expressive end to end verifiability using trusted execution environments and/or cryptography

How well it would work to paint PLA with acrylic with only sanding and without priming? Or otherwise do you know an in-office friendly and convenient priming method?

@grjte.sh in-depth post shows how it can be used in practice, what are the limitations and else the community should think about!

@grjte.shโ€™s exploration into using Wi-Fi aware for local-first chat on bitchat

Wi-Fi aware has large range, simpler authentication and is becoming cross-platform supported

@grjte.sh integrated it as an alternative to Bluetooth

๐Ÿงต Could Bitchat have 5x the range and 100x the throughput for the same power expenditure? I explored how Wi-Fi Aware could improve the reliability and throughput of Bitchat and mobile ad-hoc networks in the absence of internet connectivity. #bitchat

The Community Manager Pattern - Nick's Blog This post looks more closely at Brittany Ellich's work on representing groups in ATProtocol. It builds on earlier conversations and explores how these ideas might work in practice.

@brittanyellich.com and I have been talking about community modeling on ATProtocol lately and I wrote a follow-up piece to her recent post "Representing groups in ATProto".

Generative coding is an accelerant to get evaluations and proofs right, the industry canโ€™t avoid it anymore

Prediction: AI will make formal verification go mainstream โ€” Martin Kleppmannโ€™s blog

New blog post! โœจ I argue that AI will make formal verification go mainstream. martin.kleppmann.com/2025/12/08/a...

Three reasons for this:

1. LLMs are getting increasingly good at writing proofs using proof assistants. This will make formal verification vastly cheaper than it's been to date.
