manukall··on Ask HN: What are you working on? (October 2025)
Working on Langoustine (https://www.langoustine.dev), a feedback loop layer for AI agents.

It’s designed to plug into frameworks like CrewAI, AutoGen, or LangChain and help agents learn from both successful and failed interactions - so instead of each execution being isolated, the system builds up knowledge about what actually works in specific scenarios and applies that as contextual guidance next time. The aim is to move beyond static prompts and manual tweaks by letting agents improve continuously from their own runs.

Currently also working on an MCP interface to it, so people can easily try it in e.g. Cursor.

manukall··on How Discord Scaled Elixir to 5M Concurrent Users
I've recently launched https://pryin.io, an application performance monitoring tool made for Elixir and Phoenix. It hooks into Phoenix and gives you insights into how long your request / channels take and what Ecto queries are run / how long those take. You can also manually augment pretty much anything else (background jobs, API calls, ...). Plus it keeps track of some important BEAM metrics like memory consumption.
manukall··on Show HN: ProjectTalk – Message boards for GitHub repositories
Any feedback is more than welcome.

I added the Github issue importer functionality in part because of some threads I saw here, e.g. https://news.ycombinator.com/item?id=8712035. Now maintainers only need to tag issues with the label "Moved to ProjectTalk" and we will automatically import them and post a comment with a link.

manukall··on Ask HN : What side project are you working on?
i just started http://www.projecttalk.io

it's messageboards for github projects.

mainly because a lot of projects use live chat (gitter, slack), which i think isn't always the best solution (time zones, discoverability of past discussions, ...).

manukall··on Making a Local Web Server Public with Localtunnel
There was a post about https://showoff.io/ here not long ago. Seems they are doing quite similar things, except showoff.io costs a little. I didn't really compare features, though.
manukall··on Ask HN: weird bug?
Not for me.
