yes, even the increasing use of llvm as library, can't really be as nice as cl:compile

If you want some cool architectural changes I'd recommend reading <https://dl.acm.org/doi/10.1145/3297858.3304006>

hayley: nice paper. that makes me think that if someone just added a memory/object compiler to a lisp, we'd jump a 20% in speed

The architecture described in that paper would be implemented in hardware. Similarly though, in a general sense, CDR coding is a limited sort of compression, and Henry Baker said CDR coding should return due to memory bandwidth limits.

something that would analyze objects and their use, make them less filled with zero bits

For what it's worth I think Cliff Click did in-memory compression for tabular data, that could "decompress into registers". This compression would also reduce memory bandwidth substantially.

Nilby
yes, but with compiler knowledge, e.g. when it can be reasoned that some bits will never be used

Nilby
because i'm weird and like to scroll around memory, it's very obvious how much is wasted, with the exception of compressed media

hayley: macOS does in memory compression, before swapping out pages to disk, it swap them out to compressed memory.

Is there a lisp function to return the file name with out path and extension from a path or string?
17:20:34
pjb
dbotton: actually: (let ((path "~/.foo")) (or (pathname-name path) (concatenate (quote string) "." (pathname-type path))))

Can somebody remind me what the help channel is for common lisp. Lost all my settings. Sigh.
