#adaptability

I think this is the most important soft skill at the moment. If you do not have it, the #ai era must be super overwhelming for you.

The Bear in GitHub Copilot: Agents vs Prompts vs Skills vs Instructions A The Bear-style analogy for Copilot agents vs instructions vs prompt files vs skills, plus practical API documentation maintenance examples.

AI was easy when it was just about prompts. Now, in agent tools like GitHub Copilot or Claude Code there are multiple solutions, like instructions, skills, agents, prompt files (commands).

I wrote all I know in one article based on one of my favourite TV series.

what is your YAML chunking strategy?

just don't chunk it, dehydrate to JSON and chunk JSON

later rehydrate to YAML when agents asks for data

#chunking #rag

AI and security, hard to find a match ๐Ÿ˜

Slack has entire "join" flow broken with dummy invite link. While open collective is a really small team and it's like fiance app where community money are, so you need security that works and is easy to maintain

you have an idea already? ๐Ÿคฃ

10.01.2026 06:44 ๐Ÿ‘ 0 ๐Ÿ” 0 ๐Ÿ’ฌ 0 ๐Ÿ“Œ 0

but for small team this gives a lot of additional workflows to implement, password reset with email flows, 2fa and stuff. So for small team - that's just too much

Drama-Driven Funding

We have a new funding model for #opensource

Python F raised lots of money thanks to public drama about rejecting funds from US government. Tailwind is getting lots of donations now thanks to huge drama about AI killing FOSS.

This is where we are with open source funding.

it's pretty nifty, especially for your use case where you want to show high-level arch and then allow use to deep dive into specific section

isn't it about being efficient and delegating any security issues creator does not want to be responsibe for?

Single creators like easy flows. I'm working on something and I plan to allow login only through code in email or sms, that's it

Who's going to FOSDEM in January?

There is no API devroom or any API stand. I was thinking, maybe some co-located meetup? unconference style - but not necessarily. There are many other events already there: opensourceweek.eu

Or too late?
