FOSDEM 2025

@diffrentcolours Ahoy! I agree that monitoring without a plan to make any changes isn't that helpful.

However, I think having some data makes it easier to propose changes in future. Some other folks and I made a submission a run a devroom to ourselves for 2025, and we were looking into the options for setting up HEPA filters in case we were accepted.

This is likely gonna be a multi-year project - I'm going in with my eyes open 😅

Oh neat! If you follow - we now have 7 devrooms interested in doing indoor CO2 monitor thing! WOOT!

Here's the pad we're using to coordinate. If you are organising a devroom, or planning go to one at fosdem and would like to see some info about indoor CO2 (i.e. a rough proxy for air quality used for public health), then you can add yourself to the list below:

I posted about air quality / indoor CO2 in rooms yesterday in , and this project here appears to set up a fairly accurate in-room CO2 sensor (a SCD4x one) with a tiny ESP32 minicomputer.

The box can join wifi, and then expose the live CO2 values for scraping via Prometheus/Grafana, a well known monitoring/observability stack.

It even includes a 3D model for 3D printing the box, and sample code and links to buy the kit, for 30-40 EUR total.

Not bad!

I'm going to in Feb. If you know if any of the teams who organise devrooms or similar spaces would be open to having CO2 sensors running in the rooms, and making the values visible to participants, I'd love to know.

It feels like an affordable project to do, and quite scalable too.

Actually… I'm doing a talk in the dev room anyway. I'm happy to start with bringing a sensor of my own if there's nothing better available.

Anyone else up for it?

@floppy I don't think so, but if you know of low flying nerds going to , I think the concept of hackertrains works for geeks going from the UK to da Brux as well.

Also, TIL I learned that there is s to FOSDEM started by a bunch of ppl in Slovenia!

Here's the forum post explaining it.

Also they've sorted out a 10% discount on the European Sleeper to get to Brussels. I *just* came back from Brussels to Berlin on the ES, and I'll almost definitely take it there now.

@alexglow do you remember the ? It's becoming a thing!

Aw yiss! Got my proposal accepted:

“""
How do we work out the environmental savings from accessibility?

In this talk, we'll take a look how we can quantify the environmental savings from supporting a wider range of devices with the digital services we design and operate.
“””

I guess I better write it now 😅.

If you'd be curious about this and you have qns you'd like me to cover in the talk leave a comment.

(I can't promise to answer it before )
