Ah, @oetenergy.bsky.social is on here after all!

A new dashboard from Open Energy Transition, tracking the development and community activity of more than 200 different open source energy modeling projects. #EnergySky

We're building PUDL usage metrics dashboards with @marimo.io and have been wondering how to differentiate @duckdb.org queries coming from our WASM-based web-app:

data.catalyst.coop

and folks using DuckDB directly.

Not exactly shocking, but definitely bad. Hopefully the hourly CEMS data keeps flowing.

The energy transition continues w/o the US. Insights from a new database (not yet public) tracking more than $200B of Chinese foreign direct investment in low-carbon energy manufacturing. #EnergySky

We're also going to be able to pass through the XBRL-derived metadata and display it alongside the FERC databases, so hopefully it'll be easier to interpret what the heck is going on in the raw FERC data, not all of which is pulled into PUDL.

We're still in the process of integrating the FERC XBRL + DBF derived databases and will mirror the old Datasette URL structure so that the database & table-level landing pages work again.

Hey #EnergySky we've retired our @datasette.io deployment (which was falling over with the volume of data we publish) and are re-using the domain for our new @duckdb.org + #Parquet + #WASM based data preview interface. Check it out and let us know if anything is broken:

Like, has Meta spent more money on migrating from Python 2 to 3, or on supporting core Python development over the years?

The 🐍 Python Documentary is a lot of fun* It's interesting to see how these sociotechnical systems evolve. And the weird hobbyist vs. megacorp dynamic.

*except for the part where it takes 26 years for the first woman become a core contributor. 👋 @mariatta.ca

We'll let you know when the fix has been applied to the other tables!

The bulk data is also available via Google Cloud Storage as Apache Parquet files. The bucket contains about 20 GB of data total:

Thanks to @seerai.bsky.social for capturing a snapshot of many of the DHS HIFLD geospatial datasets before the system was decommissioned last week. You can browse it through their web interface here:
