We are putting together an automated compliance solution for environmental sustainability. Think of us as Delve.co or Vanta for heavy industries. Currently working on a new landing page. The goal is to make it easy to stay compliant when regulations get updated and maintain a positive compliance posture down to the asset level.

We just did a Show HN last week [1], but we're building dédédé (https://dedede.de/en), a place to share the "good, bad, and why"s of urban spaces. Please check it out if you hadn't already!

I'm working on spat https://github.com/Florents-Tselai/spat a Postgres extension.

spat is a Redis-like in-memory data structure server embedded in Postgres. Data is stored in Postgres shared memory. The data model is key-value. Keys are strings, but values can be strings, lists, sets, or hashes.

It's still alpha, but it works.

I'm thinking of writing an app to manage ticketing and events in Europe. There's Eventbrite but it mostly for larger cities instead of mid-sized ones. I think there could be a niche for cheaper alternatives especially since student societies get charged like 2.50 euros on top of a 10 euro ticket.

Also, writing a Masters thesis on area-level and individual-level predictors of breast cancer... so a lot of applied ML.

I am trying out a few new passive greenhouse concepts as well as experimenting with materials. Similarly, crossing some different brassica for hybrids.

Email Sanitization Service based on Dangerzone.

1. User on allow list forwards suspicious email to service directly from their inbox. 2. The email is parsed, opened, and sanitized in a sandbox environment. Attachments are scanned into raw pixel data and then converted to PDF. 3. Reply email with sanitized content is sent back to original sender. 4. Server is rebuilt, forgetting all previous jobs to protect privacy.

I'm right now working on the Managed Postgres offering for our European Serverless cloud provider, https://molnett.com/. We're building it around Neon and are happy with it so far, but are stumbling upon unforeseen issues like query modes (Thank you Pgx for not being compatible by default with PGBouncer).

Hope to launch it soon!

I’ve been mostly been getting all my shit out of various clouds and trying to get more things offline where I can control the tenancy, risk and cost.

I'm building Matrixbird - an experimental email powered by matrix.
