Programming Languages, as I learned them (pt1)

I wrote this around 6 months ago, and somehow never published it BASIC (1980-83: CP/M MBASIC, Commodore, BASICA, QuickBasic, VB6; a little bit of AppleSoft and TRS-80) Somewhere around the holidays in 1980 or perhaps early 1981, I had my first encounter with a computer thanks to one of my parents’ friends noticing I was… Continue reading Programming Languages, as I learned them (pt1)

Fun with Gentoo

Nightly auto-upgrades are great, except when they aren’t. In this case, going from app-misc/screen-4.0.3-r7 to app-misc/screen-4.2.1-r2 changed the default SCREENDIR from /run/screen to /tmp/screen. Normally wouldn’t care, but I had running screen sessions and couldn’t get in; oops! Only realized about the SCREENDIR variable after I’d already downgraded back to 4.0.3-r7.

What I was doing at age 18

I recently realized that a very important aspect of what I have done for the past year in my day job is echoing how I got started in my career. That is, I spent a bunch of time last year and this year justifying a large technical project — in writing for a less-technical audience… Continue reading What I was doing at age 18

Parts from my old (failed) attempt to build a small computer

Finally inventoried the parts after years in storage. Lot of chips, though nothing that rare or interesting. Somewhere I have the schematics I designed. Will scan them when I find them. I doubt it really would have worked, and I never got an EPROM programmer working. Very tempted to try to figure out how to… Continue reading Parts from my old (failed) attempt to build a small computer

A quick bit of FFMPEG magic to improve VHS rips

fmpeg -i Old_VHS_copy.avi -threads 0 -aspect 4:3 -vf “pp=ac/lb/ha/va/dr/al,frei0r=brightness:0.625,frei0r=contrast0r:1.05,frei0r=saturat0r:0.10,hqdn3d=4:4:7,scale=480:-1,unsharp” -codec:a libfaac -b:a 64k -codec:v libx264 -profile:v high444 -preset:v placebo Much_Better.mkv Found the frei0r contrast/brightness/saturation controls MUCH better than the MP2 ones. Amount of de-noise (before downsize) and sharpening (after) is to taste, obviously, as is the amount of brightness/contrast improvement. This source was AWFUL!

Commodore Nostalgia

via Slashdot, Programming Books, part 3: Programming the Commodore 64 Prologue about the book itself is worth reading, but the following really resonated for me: Now I know that there is already plenty of old-fart nostalgia on this blog — a lot of people have interpreted Whatever happened to programming? as a yearning for the… Continue reading Commodore Nostalgia

Server upgrade

I doubt many folks are still reading it, as I know my handful of old friends who read regularly are all on Facebook now and seeing my updates there. Nevertheless, my file/web server has been down for a week or two and is only back up. It’s pretty much been totally replaced, hardware-wise. Specs (aka… Continue reading Server upgrade

Someone with a web server and a sense of humor…

Ebuyer.com runs on a Commodore 64 Online retailing can be a rough sport. The competition is rabid, customer loyalty is fickle, and IT expenses can go through the roof. That’s why The Register can appreciate an e-tailer with a unique business model. A hawk-eyed El Reg reader points out that UK online retailer Ebuyer.com appears… Continue reading Someone with a web server and a sense of humor…
