Lisp is dead ? No, just lispers.
Came across this quote from the "Naggum-mine": Many Lisp programmers demand that sockets and multiprocessing should be standardized before they want to use it, which penalizes creativity li…

Rutils ?
I was excited to try this out when I came across it ... but it looks like (today!) the github repo is not in a compilable state, at least on Allegro CL. CL-USER(44): (ql:quickload 'rutils) To loa…
BotWorld -> BotVerse
I came across this paper (actually a literate haskell document, pretty cool!) from MIRI. (What's MIRI ? I suppose someone finally convinced the "Singularity Institute" they had a terribl…
Defstruct and Defclass as macros
The SBCL version (macroexpand-1 '(defstruct spoint (x y))) (PROGN (SB-KERNEL:WITH-SINGLE-PACKAGE-LOCKED-ERROR (:SYMBOL 'SPOINT "defining ~…
Fixing a SLIME/Swank version problem
Installing a bunch of packages willy-nilly resulted in this configuration problem for me: starting slime resulted in this frustrating error message: Versions differ (2014...) slime vs (2009...) swank…
Capitalizing words; the flexible format directive
From an exercise in the second chapter of PAIP. This takes a list of words and prints them in a list, with the first one capitalized. (defun print-words (wordlist) (format t "~&~@(~A~) &…

I created a million instances of each (the structure spoint, and the class point), with randomized members, and the former took about 50 milliseconds, while the latter took about 100 milliseconds. Wit…
So much for the AllegroCL trial
I suppose it's worth learning anyway, it seems to give a very precise control over compilation, has a bunch of libraries and is very well documented. Also, an email to [email protected], which tur…
AllegroGraph: Getting Started
I'm following along with Mark Watson's excellent book on using AllegroGraph, but the automated install mentioned at the beginning didn't work for me. While I figure this out, the followin…

… the programming environment model in Unix is an imitation of the Lisp machine, and the way it is implemented is through processes and inter-process communication instead of function calls. Function…
Lisp Books
This is something I've always pieced together bit-by-bit, and I'm sure a lot of other people have done the same by combining occasional blog posts, reviews on Amazon, perhaps a few mailing lis…

Arguments over syntax aside, there is something to be said for recognizing that a loop that steps only one variable is pretty useless, in any programming language. It is almost always the case that o…
