And about Volume 5...

Syntactic Algorithms, in preparation.

9. Lexical scanning (includes also string search and data compression)

10. Parsing techniques

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.

"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.

That "Another angle" truly is spectacular.

Just fyi, the author is https://en.wikipedia.org/wiki/Glyph_Lefkowitz, creator of Twisted.

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".)

Finally, a bracket I can enjoy (that doesn't involve basketball).

I think Claude Shannon’s spirit is probably proud to know that his name is now being associated with such advances. Hats off to Claude!

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/

Yesterday there was a somewhat similar DuckDB post, "Frozen DuckLakes for Multi-User, Serverless Data Access". https://news.ycombinator.com/item?id=45702831

Looking up the etymology of "sargeable", I found this StackOverflow answer: https://dba.stackexchange.com/a/217983

And Google explains "The term 'sargable' is a portmanteau of "Search ARGument ABLE," formed by combining the words from a SQL database context."

If you want to do this rigorously, I suggest you read Robert D. Cameron's excellent paper "REX: XML Shallow Parsing with Regular Expressions" (1998).

https://www2.cs.sfu.ca/~cameron/REX.html

That must be for "Dissolution and crystallization of cobalt, copper and sodium chlorides". It's quite something to watch!

should buy the books

Yes I totally will, err..., oh my, ebook for $91.99, paperback for $127.99. What's going on with these prices? These aren't college textbooks. I'm glad to hear about the 3rd edition but the cost gives me pause.

The paper they've submitted goes into a lot more detail. https://royalsocietypublishing.org/doi/10.1098/rspa.2025.029...

And it has a Python wrapper, https://github.com/argolab/dyna3/tree/master/dyna_python_mod....

Wait, so this object is going to pass quite close to Jupiter, Mars, and Venus? And the Juno probe, which was planned to be decommissioned soon anyway, could potentially be maneuvered to follow and get close to the object? Kind of uncanny and kind of a science fiction plot, but fun to think about.

Hi, just wondering what you're thinking about how your tool might be abused.

An overview of other studies investigating cysteine and glycine sources and effects (from 2023; video or transcript):

https://nutritionfacts.org/hnta-video/how-to-get-less-cystei...

LLMs trained on LLM generated material trained on ... until just gray goo is left.

So I wonder how much of Claude's perceived personality is due to the system prompt versus the underlying LLM and training. Could you layer a "Claude mode"—like a vim/emacs mode—on ChatGPT or some other LLM by using a similar prompt?

Make sure the check out the LLM chat log he shared for the current article! The tone is cynical HN commenter indeed.

Alright! We managed to plot two sine waves in the most convoluted method ever!

Those sine waves start to resemble a multi-voice music score. You might get some interesting pitch variability depending on other processes that are running.

The author is Co-founder of Databricks, creator of K Prize, so an early adopter.

Interesting article relating Adam Unikowsky asking for Claude to decide a Supreme Court case: https://blog.plover.com/tech/gpt/presidential-emoji.html

"Claude is fully capable of acting as a Supreme Court Justice right now."
