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.

RSS- Working on an old boat today. Just pulled these off of the deep cycle battery. Both red. One was on the positive and one was on the negative. They run under the floor… and the wire chasing begins because the colors sure aren’t right and they aren’t labeled.
- This is week’s books to devour. Really looking forward to these.
- A week diving deeper - PET: Cramming code into single lines isn't just for Perl programmers. Here are two one-line subroutines to convert hex to decimal and back. Hint: you have to use the shortened keywords to get them to fit in 80 columns #PETober #commodore
- A week diving deeper with the PET: Since I have a fair amount of Commodore experience, seemed prudent to think about and work on text screen program UI concepts. A loan calculator is even a useful one to have on disk in 2021. #PETober #commodore
- A week of diving a little deeper into my Atari 800XL · imapenguin
- Some thoughts on my week of "diving deeper" with the Atari 800XL.
- New to me 1962 Olympia SM7. It’s in amazing shape. #lessfeaturesplease
- My week with the Atari 800XL is over. I’m writing up my thoughts and some things I learned. In the meantime, this one is next. #octaci #PETober
- Was just thinking “it’s 3pm and I’ve been super productive today, I wonder why…”. Oh right, that’s why.
- Diving into Atari 8 Bit: Horizontal movement is pretty straightforward. Vertical is a little more tricky. Using an ML program and calling it via USR() makes it MUCH faster. Still having fun(ish). #octari
- Two weeks with a Coco 2 in September · imapenguin
- Two of my favorite distraction free productivity tools
- This chip is still on my desk. Even though I’m one of the people who has the thermal printer it goes in. The mystery was cooler than the reality. #commodore
- Diving into Atari 8 Bit: XIO is completely new to me. Combined with joystick inputs to draw a "road". Pretty fun. #octari
- Diving into Atari 8 Bit: More graphics learning and using TRAP which is very nice. Pretty impressed at how well graphics work even in BASIC. #octari
- Diving into Atari 8 Bit: I'm actually off today, but always 5 minutes to learn something. Quick color and plotting. Atari BASIC makes this stuff really easy. #octari
- Diving into Atari 8 Bit: Getting a handle on CTIA chip capabilities. Shading is a pretty cool feature #octari
- Diving into Atari 8 Bit: Reading joysticks is really easy, and Atari BASIC is good enough to make joystick movements smooth in BASIC. Neato #octari
- A little lunchtime fun: revisiting this old maze listing to see if we can get it to be just a little more random. Atari BASIC sure is slow #octari
- The 3.10a Firmware update for the Ultimate II+ seems to have resolved my long time C128 disk access errors on this particular machine. Neato. #commodore
