For a NOAI.md, how about something like this?

Build times in a Rust project can be long. Sometimes even several minutes.
In my experience build times in an Android project average about a day.

Have you made something recently? Maybe a FOSS project you started or contributed to? Or some knitting?
I'd love to hear about it.
Go on, cheer me up.

I just wrote up some docs on how to hide images in public rooms on Matrix in several clients.
https://matrix.org/docs/chat_basics/public-rooms/#hiding-images-by-default
If anyone was able to add info for more clients that would be awesome. Here's my change for reference: https://github.com/matrix-org/matrix.org/pull/2971

Have you seen my video series "Writing a programming language"? I write the smallest, simplest possible language I can think of, and walk you through it.

Did I mention that Exclude Insecure Devices is coming?

Important message from my talk!
Exclude Insecure Devices is coming!
After April 2026 (or maybe even sooner), if your Matrix device is unverified, you will not be able to talk to someone who is using Element!
Or any other client complying with MSC4153

My talks at #MatrixConf2025 are tomorrow 14:00 CET and 16:00 CET. I am talking about our progress on "Invisible Crypto" and agreeing a shared terminology to talk about Matrix encryption. Watch live at https://conference.matrix.org/watch/ . Recordings will be available later too.

it looks to me like a bug in the spec change that introduced OIDC for authentication: as part of that change, there should have been a deprecation of this endpoint, because it doesn't make sense in this context.
I'm not saying that matrix.org should be the de facto standard, I'm saying that (I think) there is a bug in the real standard, which has become visible when matrix.org implemented it.

Maybe a bug logged against the spec is the right way to track this? https://github.com/matrix-org/matrix-spec/issues

at first glance it looks like deprecating that endpoint was missed in the spec proposals for OIDC login.

I tried to understand what you're saying but I can't figure it out without more context.
Is there a bug logged against Synapse?

Submitted two(!) proposals for talks at the Matrix Conference[1]. If any are accepted I guess we'll find out whether I really am ready for the pre-talk stress (from which I have been taking a break for a year or so).

Poorly-copied answers ripped off from stackoverflow and wrapped in a patronising tone are putting stackoverflow out of business.
https://devclass.com/2025/05/13/stack-overflow-seeks-rebrand-as-traffic-continues-to-plummet-which-is-bad-news-for-developers/
meaning there will be no more information to rip off.

Musings on the order of messages in Matrix
https://artificialworlds.net/blog/2024/12/04/message-order-in-matrix/
It's surprisingly hard to say which message came first!

If you want to learn how #matrix works, I really recommend https://uhoreg.gitlab.io/matrix-tutorial/index.html by @npub1e6k…9kpc

Really sorry to be missing the Matrix Conference, but at least able to watch on the live stream!

I have been shepherding a Matrix Spec Change that tries to choose easy-to-understand wording to explain Cryptographic concepts to non-technical users.
I think the first draft is ready! Comments and suggestions welcome.
