And about Volume 5...

> Syntactic Algorithms, in preparation.

From Future Plans...

> And after Volumes 1--5 are done, God willing, I plan to publish Volume 6 (the theory of context-free languages) and Volume 7 (Compiler techniques), but only if the things I want to say about those topics are still relevant and still haven't been said. Volumes 1--5 represent the central core of computer programming for sequential machines; the subjects of Volumes 6 and 7 are important but more specialized.

New comment by jdnier in "The Ü Programming Language"

"Ü programming language" brings up the Github docs with Google, as does "U programming language", although this HN post comes up second.

On a Mac "Ü" is typed "option-u shift-u".

Some more resources from that post:

> See examples (https://github.com/Panzerschrek/U-00DC-Sprache/tree/master/s...) to get a general idea what Ü is and how it looks like and feels. Read the documentation (https://panzerschrek.github.io/U-00DC-Sprache-site/docs/en/c...) for more details. If you have some questions about the specific mechanism providing safety, read the corresponding chapter (https://panzerschrek.github.io/U-00DC-Sprache-site/docs/en/r...). If some topic isn't clear for you after reading the documentation, contact me and I can answer your questions.

There was a "Show HN: Ü Programming Language" from the author last October.

The parent reads more like "it works in practice but does it work in theory?" The innovations that have come out of the DuckDB team seem to always focus on "in practice" instead of focusing on how things are supposed to (or are expected to) be done.

Looking more carefully at the original image (http://www.thehistoryblog.com/wp-content/uploads/2026/04/Emp...) I can see the mapping of letterforms you made. Thanks for that!

Not understanding Greek, I ran that through Google Translate (Greek -> English) just to see what it might say.

> AND THIS … THE MAJOR … BUT THE BOTH … ARE MEANING … PEUSIS PAN GAR SEEMS.. OBVIOUS.. SPECTRA … OF SONGS SO … MAJOR … AND THEREFORE … NOT EVEN EARS .. NO LANGUAGE

What form of Greek would that be? (I don't know much more than "ancient Greek" vs "modern Greek".)

I didn't realize Claude was named after Claude Shannon!

I had not heard of Glyphs, the tool the author used. I used to use Fontographer long ago.

It's a great article!

DuckDb has a new "DuckLake" catalog format that would be another candidate to test. https://ducklake.select/
