I'm launching neoserver, an open-source geospatial server written in Go: OGC API Features & Tiles, WMS 1.3, WFS 2.0, WCS and WMTS from one binary, managed via a REST API and a built-in admin console. A lightweight, API-first alternative to GeoServer. github.com/tobilg/neose...

If you avoid weekends or start early it should mostly be fine… Another thing is the height, I live barely above sea level, and the first 2-3 days may be tough. The passes are all at 2000-2450m. I can see this e.g. in my resting heart rate that’s 10-20 beats higher than usual during sleep.

I used my roadbike this time… Riding on these streets is generally safe I‘d say if you‘re used to public streets. Descending at top speeds north of 60km/h can be tough especially if you’re riding the first time on these roads. I use a Garmin Varia 515 radar that warns you about approaching cars.

Tobias Müller @tobilg.com · 07/09/2026
I can share the routes when I‘m back home, on mobile it’s a bit difficult, the Garmin app sucks… I choose routes where I can shorten them with trains if necessary, that give me some peace of mind. I used the RhB from Tirano -> Pontresina on the way back yesterday. 1600m elevation were enough

I benchmarked the new Polyglot v0.6.0 Python package against a set of other SQL parsers for Python, and it seems to hold up pretty well... It might even be the fastest SQL parser in Python land
