I write about the past, present, and future of technology across three sites. imapenguin.com explores retro computing and programming fundamentals, milkcrunch.com covers modern software development and engineering culture, and evadot.com examines commercial spaceflight and the new space movement.

- Afternoon walk is starting to feel like November.
- Well, it’s a good start. Just need to do that 29 more times. It’s not even 7am #NaNoWriMo
- Same Sierpiński's Carpet program but with PETSCII instead of graphics. This is a job for a PET! (2x speed) #commodore #PETober
- Sierpiński carpet on the Apple IIe took 3 1/2 hours. Here sped up A LOT. Machine language version is next and should be WAAY faster #appleii
- I’m doing #NaNoWriMo for sure, but looking for another thing in November to also dig deep on. I’m thinking about mashing these two concepts.

- Quick Tower of Hanoi with Sound on the Commodore 64 · imapenguin
- I LOVED @Ayliean's Tower of Hanoi video on @numberphile this week. I wanted to try it with some "soothing" sounds from the 80s with the SID from a Commodore 64 #commodore #c64 (sound on!)
- Warranties are for losers.
- I just picked up this 386 laptop from a guy up the road from me. New in the box. I literally cut the plastic from the factory on it
- TI-81 Screen pixel issue was a manageable repair. Took just a couple minutes. Reflowed the solder on all of the ribbon cables with the hot air station. She's all set for 30 more years of mathing.
- Well this is sad. My TI-81 has developed a column of dead pixels. I wonder if I can replace the LCD.
- Neither my son or the dog care that it’s way too cold to be in the river today.
- A little lunchtime fun: I have my Commodore PET Tic-Tac-Toe "AI" playing against itself with about a 95% tie rate. A couple more tweaks and I think I can get it to 100%. #PETober #commodore
- Started wearing a 30 pound weight vest on my daily lunchtime hike. Feels really good. Also I think this is the longest my hair has been since 1992.
- A week diving deeper with the PET day 1(take 2): I stand corrected, the COMMODORE PET is a graphics powerhouse. Better graphics than any other computer invented since 1977. #commodore #PETober
- Have had a great week with the Atari 800XL and then another with the VIC20. This week my choices are:
- You know the boat electrical repairs are getting serious when the bench power supply gets moved in.
- Wrapping up a week with the VIC: Unexpanded VIC with a keyboard version of Breakout. Getting a fair amount of help from machine language here, but it's a very playable (and simple to code/understand) version. LOVED this week with the VIC and appreciate it even more! #VICtober
- A week diving deeper with the VIC-20 day 6: Pretty much the best graphics of any computer ever made. #VICtober
