Good point. This is for data that's not in use.

Here's a quick one if your filesystem supports hard links: #!/bin/ksh typeset -A hashes find . -type f -exec shasum -a 512 {} \; | while read hash filename; do if [[ -z ${hashes[$hash]} ]]

This is mean to be a simple and straightforward implementation of the RSA encryption algorithm in Common Lisp. Review would be greatly appreciated. This code does not solve the key exchange problem or do any transport.

How appropriate the day after finding the Task Manger in Chrome for the first time yesterday. Finally got my fan to turn off on my laptop.

No, the ability for the machine to not crash or need to be rebooted for long periods of time. Linux has gone completely downhill in this respect for the past few years. Switching to Solaris on my main Unix workstation has been a breath of

One of the only reasons I had "The C Programming Language" on my desk when I was a C coder. The only thing I could never remember...

Thank you for sharing your work. I could see some good use out of it.

It's not pretty, but it has a consistency to it that includes a lot of compact information in a digestable manner. It takes no longer to decode what the instructions say, but it saves a lot of time parsing, for the human reader of the

Good point. Haven't seen that example before.

If anybody is interested in some 'current' open source MS-DOS software, I put up my old undergraduate thesis sources from 1997 recently: https://github.com/burtonsamograd/xp32 Te repo has a full DJGPP

car and cdr may not be the best names, but they allowed for composition, like: (caar x) == (car (car x)) (cddar x) == (cdr (cdr (car (x))) Something which you can't do with first and rest. This has (AFAIK) always been one

Unlike NULL (a void* of value 0), nil is an interesting construct in that it's a special cons cell, an element of two pointers, where each cell points to itself. Or that's one way to think of it.

To run: Open raytracer.el M-x eval-buffer M-: (ray-test 256) Output will be in a buffer as well as 'image.pbm'.

I get the ACSII part, but what would be the purpose/intent of the 'lazy DAG transformation on eval'?

I've also written a GPU tracer using the same style of calculation, and it just blows anything done on the CPU out of the water. It gets about 10fps with 100 spheres on a mid range Mac Pro.

It's built to test the JIT but shouldn't depend on it. To run: Open raytracer.el M-x eval-buffer M-: (ray-test 256) Output will be in a buffer as well as in 'image.pbm'

Thank you. I tried to stay as much with the 'grammar' of C but with the syntax of s-expressions. Whatever came out most naturally as a C programmer was what I used in the S-Expr language.

cmacro is it's own language that doesn't have the power of Common Lisp. Same with magma; to each their own, but I prefer the capabilities of CL over a homegrown macro language.

In the end, that's where it's true power would come from where you use the capabilities of the much higher level language to compile ideas to the lower level language. ALso, this allows for far greater compile time data generation
