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.

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).

one of my favorite recurring gags in the Simpsons is characters walking away and a sound effect immediately playing the second they're off screen

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

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.

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.

My microphone has been deliberately kept faulty again and again. I am trying to speak, but I cannot be heard properly...."

I just found out the latest version of #substancepainter has a brush strokes filter. Makes life very easy to get a painted look. I made a basic shader in Substance Painter (you can see it for a few seconds towards the end of the clip) and then modified the shader in COPs.

dbrand has sold out of both versions of its Companion Cube case for the Steam Machine. >The full Companion Cube version costs 129.95 dollars. It includes a special box that looks like a test chamber, a skin for the Steam Controller, and other extras. >The simpler Poverty Cube version costs 99.95 dollars and comes with basic cardboard packaging. Both versions sold out quickly on the dbrand website even though the Steam Machine itself is not shipping until summer 2026.

🚨 I believe I discovered something that can be added to the timeline and could potentially conflict with Frank Tureks’ statement of going on a walk with Charlie around 8pm MST on the 8th. On Sept 8th, 6:15pm - Roughly 9:10pm MST the Vikings v. Bears game airs. The following day, Sept 9th, Charlie appears on The Charlie Kirk show, and per his emotional rant on the Bears loss, it is clear that he was heavily invested in this game, specifically, the second half. Charlie stated that he was screaming at his TV and “woke up everyone.” I can only assume he is talking about his children here. Remember the game ended at roughly 9:10pm. The second half of that game would have indeed, eaten up the entire 8 o’clock hour. Per Frank Turek— This was a “long walk.” Do you believe Charlie could have fit in a “long walk” with Frank at around 8pm, all while watching the second half of the Bears game, which came to a close, again, at roughly 9:10pm?
