An Emacs buffer working on some Emacs Lisp code.
Time to implement https://github.com/davep/blogmore.el/issues/17 I guess. Then I can have ALL THE BLOGS!

Unexpected numerological finding. I'm allocating memory for objects in sizes that are powers of two, in order to be able to manage separate freelists for each size to make GC easier. My hashtables have a header overhead of 4 words. My namespaces need a write access control list and a mutex in […]

OK, folks, I've written yet another incomprehensible essay on the intricacies of implementing a software environment for the hardware of the deep future.
Read this only if you're incurably geeky, and, ideally, interested in #Lisp.

Modern Medley Interlisp can read and write files where 16 bit character codes are represented as UTF-8 byte sequences or UTF-16 byte-pairs, and convert from and to Unicode codes to equivalent internal Medley codes. For details see:

#Lisp people, do you have a preference for the name 'hashtable' or 'hashmap'? In #Java, there's an actual semantic difference, since Java HashTable is not thread safe while Java HashMap is.
I am building things which are thread safe. My inclination is to call them 'hashtables', but is this now […]

[Implementing infinity in Lisp arithmetic]
David fucking Hilbert wrote 'after infinity, counting continues naturally, infinity plus one, infinity plus two, and so on' (I'm quoting from memory, so could be slightly wrong).
I consider this anathema. I'm proposing that any computation which adds […]

@atgreen.bsky.social is using AI to great effect for the Common Lisp community.

Some folks don't like it, but having a lot of useful libraries for an older language with a small community is a net positive IMHO.

In the late 1970s Interlisp was ported to DEC VAX computers under Berkeley Unix. These papers reported on the project and its challenges.

The Xerox D-machines (Dorado, Dandelion, Deabreak, and a couple of others whose names I forget) used processors which weren't strictly Lisp-specific silicon, but they did run #Lisp specific microcode, which is interesting in itself.

In researching that essay I've reminded myself of two very old papers on building #Lisp specific processors.
There's one on the Symbolics Ivory processor here -- this was a real commercial product, not just a research experiment:

I've written another essay about my mad #PostScarcitySoftware #Lisp system.
"We don't need to know, or have known, these people to build on their work. We don't have to, and cannot in detail, fully understand their work. There is simply too much of it, its complexity would overwhelm us.

For the first time in *years* I've just sat in a coffee shop and hacked on some Lisp. https://github.com/davep/blogmore.el/pull/1/changes
T'was fun. Also realised my Elisp is a wee bit rusty.
