https://dmarcdefender.io. DMARC service focused on api/integrations. Currently thinking about (1) writing an ml classifier to classify sources, and (2) using rag to automatically generate spf/dkim fix advice for different sources.

Two free dmarc tools: * dmarc domain scanner https://dmarcdefender.io/tools/domain-check * dmarc xml analyzer: https://dmarcdefender.io/tools/xml-analyzer

https://battlecode.org/ is in January, I look forward to it every year.

This is awesome! I can't believe I've not heard of it before. Thanks for sharing!

I do security Capture The Flag (CTF) writeups on YouTube. It's been fun, I've learned a lot, just published my 100th video.

Not sure if this is interesting to the HN crowd, but some challenge writeups from a recent security Capture the Flag competition.

Going back to school for Physics (age 30). It'd be cool to understand why the universe exists before I die.

> It'd be cool to understand why the universe exists before I die.

I'm affraid physicsts aren't interested in this question (as it can't be answered by science).

Might be able to get enough understanding as to "what we have" (if not "why we have it") to be content for a human lifetime, though.

Ah thanks for the heads up. We'll wrap it in a html picture block. (Google's https://web.dev/measure/ recommends webp, but I should have done more research)

> Interesting article. How much requests can you support for 20/month before losing money with this stack?

Ha, I haven't profiled it yet. I'm not too sure. But, I think a decent amount. If a slack team with 10000+ physicists signs up, I may need to talk to them offline.

I do plan on doing some stress testing in the future for fun, I'll try to remember to reply here.

> partner frontend

Yep, to repeat what steve_adams_86 said, she did the frontend completely. Usually I'm forced to do the frontend, it was very nice having someone else just do the whole thing without me.

Teams with this number of physicists exists only in CERN which uses self-hosted mattermost. Don't worry from that for now.

Thanks for the insight!
