Continuing my fun with the Enigma machine: I wrote two emulators for a Commodore 64, one in BASIC and the other in Assembly (Turbo Macro Pro, coded on a C64). The BASIC version does about 3 characters per second. The assembly version can encrypt/decrypt roughly 1500 characters per second.

BTW, the assembly version is 1219 Bytes to implement a working Enigma. RAM shortage, pfft.

TMP is the program I loaded the most on my C64. I feel at home with it. I use the REU version.

Struggling with the basic version. It loads, and after loading my C64 hangs without even running the program. No trailing characters in the bas file as far as I can tell. Really strange.

Tried on an original breadbin, a 64c and on my Ultimate. Really weird.

Progress! My wife recorded a demo of the current state of FranKIMstein. I now have the Commodore BASIC interpreter running on a 1541 disk drive and I can run BASIC programs, then save them and load them on a Commodore 64.

When I was a kid, I learned SO MANY math and computing concepts from Logo on the Commodore 64. Recursion was a big one. As a seasoned technologist, I'm still blown away by how much they packed into a single 170kb floppy to give a simple 8-bit computer so much power and flexibility. It's only now that I've started playing with the built-in assembly language interfaces in Logo. Something that was completely over my head as an 11 year old. Here's the kind of thing I did a lot of in the 80s (and even understood most of what I was doing).

If you owned a Commodore 64 in the 80s, you probably did this. You didn’t download apps. You typed every single line of BASIC from a manual and prayed it would RUN. Hours of typing. One typo. ?SYNTAX ERROR IN 240 Did you ever get it right on the first try? #c64 #commodore64

Elon Musk explains why Neuralink is so important in the age of AI: Human output bandwidth is roughly 100 bits per second Computers can communicate at around 1 TRILLION bits per second “Biological enhancement with Neuralink, this company I created with some other people. We want to try to solve the bandwidth constraint that humans have Because imagine, even in the most benign scenario where the AI is super friendly and wants to do everything it can, wants to make you happy, our rate of communication is too slow So peak human bandwidth is only about 100 bits per second, roughly. Our input bandwidth is much higher because of vision....a megabit per second or a few megabits per second from our eyes, which are effectively like cameras But our output bandwidth is really low Computers are communicating at a trillion bits per second Anything we can do to increase the communication speed of humans will improve, I think, the alignment of humans and machines Because otherwise, to an AI that is communicating at a terabit a second, talking to a human will be like talking to a tree”

5 facts you didn't know about Kung-Fu Master, the classic 1985 Commodore 64 game from Data East (Developed by Berkeley Softworks): 1) On level 1, you could hold down the Shift Key and G for a gun, as seen in the video. This only worked on level 1. 2) An add-on to the gun cheat: press Shift and G and stand still for 1 second to show "By Chris Hawley" and then reset to the start. 3) Chris Hawley never made another game. 4) The USA Floppy disk was a Flippy Disk. On one side was the Commodore 64 version and on the other (flip it over) had the Apple II version. 5) The game is loosely inspired by the Jackie Chan movie Wheels on Meals. Have you watched it, and do you see the similarity? Bonus fact: You may recognize the developer, Berkeley Softworks, from GEOS. This game and Karate Champ were the only two games they made before creating the very successful GEOS for the C64.

⚠️Re-creation I can finally generate characters in swimsuits. Wan has a standard version and a prime version. It feels like they’re copying Seedance VIP. The main difference seems to be the generation speed.

Still my favorite digital camera. Waiting for the 40 second for the floppy to stop spinning per image and about 8 pictures in high resolution makes one contemplate the subject. I shall post some images soon.

How about an encore for AaronSabato. He drills his second homer in as many at bats, this one the opposite way. It's his second two homer game in two weeks and ninth of his career. He is 3-4 with a double, two homers, three RBI, and two runs scored on the day

Shot on Vision Pro - Apple sent me the new Vision Pro with the M5, and the moment of opening the package will always feel surreal. The unboxing itself was extremely fun — though I did feel a bit guilty about my old Vision Pro. I made her watch the whole thing… so now you can too now. If you have a Vision Pro, you can watch the spatial version in the comments.

Unitree G1 ran about 13 km in two hours on a livestream - averaging around 1.8 meters/second - with two battery swaps along the way. At that pace, a half-marathon would take roughly 3 hours and 15 minutes.
