Extremely high concurrency at sub-second response times.
Here is our write up on the Ducklake blog: https://ducklake.select/2026/07/29/bringing-ducklake-to-data...

Thanks for the shoutout.
For context, we previously built custom catalogs optimized for specific use cases. But they were hard to maintain, especially as requirements changed, and Apache Iceberg was too heavy for our specific low-latency work.
Since Ducklake is only a spec, we implemented datafusion-ducklake, and it performs as well as any custom or specialized catalog we built. We use Postgres as the catalog store, and it does not get much simpler than that: a transactional database for transactional data.
Plus, it gives us a clear spec for implementing complex parts like time travel, snapshots, etc.
It's been a godsend.
We welcome and encourage contributors!

Plastics are petrochemicals, meaning they’re made by combining fossil fuels (usually fracked gas) with chemicals. Petrochemical plants are among the most polluting industries in terms of harmful air and water pollution, and greenhouse gases. In the US, most petrochemical plants are clustered in a low-income, largely Black area of Louisiana known as “Cancer Alley.” So from fracking, to chemical production, to petrochemical manufacturing, people and the environment are harmed—that’s not even counting the end of the plastics lifecycle, like ocean pollution and incineration.
The concern:

There are lots of issues with bitcoin, but the inherent value one is the least interesting.
Clearly, some people think there is value. That's it.

While mostly true, let’s put this into perspective: A GS-15 in a metro area like New York, DC, and San Francisco, with experience, can get over $170. Throw in performance bonus and matching contributions, and total compensation is $180k+. That does not compare with the high end of the private sector, but that’s reasonable for a lot of people, even at tech companies.
You can estimate here: https://www.federalpay.org/gs/calculator
Also, the sense of duty and serving the public is real. And this is not expressed in a tongue and cheek way... it’s an earnest desire to do meaningful work.
Many people who join USDS, 18F, and PIF from the tech industry are there because they genuinely want to do good work.

If you interested in seeing how the 3x3 initiative* has come along, here are the benchmarks so far: https://github.com/mame/optcarrot#readme
Personally, I am very excited for this release.

I recently started using Sinatra for side projects and it’s an absolute pleasure. It’s simple and reliable. I think it should get a lot more recognition.
