Folks, this WordPress blog will soon disappear. I’ve wanted to get rid of WordPress for a while and half-wrote some blog software back in Spring 2011. Some coworkers had a similar plight so we all agreed to finish our blog engines in a one week sprint. I’m done and will likely switch over in the coming days. My livejournal, for those of you still ( Read more... )

A random walk through 30 years of history…

1960s: Lisp, Simula, Algol, our hallowed forefathers

1971: Unix released in Assembly, the advent of time

1972: Unix ported to C or, the advent of Portable/Commodity OSes

1973: ML interpreter in lisp appears, the advent of Typed FP?

1974: Deutsche+Greenblatt, the advent of LispM Dreams, fast implementations

Going into this project, I knew almost nothing about emulation. I still know very little. But I was tired of seeing emulators written in C and Java for performance or portability that wound up looking like a big switch statement sooner or later. My 6502 emulator is ANSL CL and should run anywhere that sbcl, clisp, ccl, or any other fine Common Lisp ( Read more... )

Lately, I’ve been working on an emulator for the MOS 6502 processor in Common Lisp that I’ve been boring enough to name cl-6502. The emulator is basically finished as is the disassembler. There are also pretty solid docs. An assembler should be added soon and hopefully a helper utility or two and unit tests. But why do this? Well, for a couple of ( Read more... )

Strange Loop has posted their schedule for 2012 and my company has been kind enough to send me. Without further ado, here’s my current thought on which talks I’ll attend. I just can’t wait for September.

My posts on this blog have leaned away from technical content for the last year, tending towards the introspective and music or poetry. I’m hoping to start shifting back in the other direction for a little bit and plan to write about my latest personal hacking project soon. In the interim, here are 10 favorite albums to write code to off the top of ( Read more... )

It’s been 3 years since Dad died, 2 years since I’ve been single. It’s hard to believe, really. And wouldn’t you know, I had a dream about Dad for the first time in a while. He had cancer but was still alive. We’d all moved back to Cross Creek where I’d spent the first decade of my life or so. I had my job at CMG, I think, and I was talking to Dad ( Read more... )

I’ve been working on some of the depression issues mentioned a few posts back, making progress. Been making a concerted effort to have fun. Lots of weekend trips to Athens, socializing, concerts, that sort of thing.  Starting to create things again too! I’ve made a mixtape for the first time….like a proper mixtape. Did it in Audacity. Didn’t try to ( Read more... )

I need another dose of Milosz. Perhaps you do too. Here we go…

Guardian Angel

In my dreams my guardian angel takes the form of a woman,

Not always the same one. He knows that I, a fleshly creature,

Need a lover’s touch. We don’t make love,

But there is a closeness between us, and understanding.

I never believed in the presence of angels, but my ( Read more... )

Disclaimer: This is going to be a much more personal entry than normal. Just to get down some recent thoughts and revelations that I’ve had. I’ve read people talking about blogs as subject-focused, about building them almost like products. But this thing is a record, a mosaic, and a journal. So here we go.

On and off depression is the one thing I ( Read more... )
