To conclude the series on using #NDB interpreted code (IC) programs with #RonDB I decided not to write more blog posts but rather two formal research papers, which I presented at The 19th European #Lisp Symposium (#ELS'26), Krakow, 11-12 May 2026. #Dydra

This is the third article in a series on using #NDB interpreted code (IC) programs with @RonDB_ai and discusses an example of a very short but still very useful interpreted code program. It describes the actually essential implementation for Dydra.

This is the second article in a series on using #NDB interpreted code (IC) programs with #RonDB and it just tries to work out how accurate the #MySQL documentation still is for its fork RonDB. A question that I had for a long time.

This is the first article in a series on using #NDB interpreted code (IC) programs with #RonDB. And how the compiler I wrote for it made the task much simpler. Allowing not only to compile to NDB interpreted code but also to a #Lisp backend for debugging.

What if your #database could remember everything—every edit, every state, every version—across time, while scaling effortlessly beyond the limits of a single machine?

After more than a year of work, we just released a much enhanced version of our #CommonLisp bindings to the C #NDB API of #RonDB.
So, welcome cl-ndbapi for RonDB 24.10!

We are currently working on a series of articles, how we use it to scale #Dydra.

Did you know that our #JavaScript web client library can act as a #replication node of the #Dydra graph store?
This means, all changes are automatically pushed to your web client applications (background change notification). See dydra.github.io/replication.…

We are working on ways to distribute not just data storage, but also query processing. A new capability of #Dydra and #RonDB allows us to push the test to the data instead of having to pull all data to the test, greatly reducing the data that has to move.

Got my amateur radio certificate class A yesterday!
A day later the "admission to participation in the amateur radio service" already arrived. The people @BNetzA are really quick (and very friendly on top of that)!

What all to learn on @vseloved's page at vseloved.github.io/! I didn't know that Grammarly is written in #CommonLisp. There is an article on that at grammarly.com/blog/engineeri… #Lisp
(Also, I didn't know @Grammarly was founded in the #Ukraine: grammarly.com/blog/support-f…)

Just ordered a physical softcover copy of phoe's The Common Lisp Condition System. For some reason, there is a 72% discount on it at Springer's web shop:
"Current total: 9,99 € Includes VAT/Sales Tax"

Oh, and also Vsevolod Domkin's Programming Algorithms in Lisp. Same price, which in this case equals a 67% discount: "Current total: 9,99 € Includes VAT/Sales Tax".
