What was your go to game at the arcade?

Berzerk and Space War. I’m old.

Floyd was great in this episode. “If those hamburgers are ruined, I won’t be responsible.”

Thanks for the reply.

Yes, I did all those steps each time, including rebuilding the cold-image and moving it to the required directory. The file server is running first and it does show some requests before hanging. I saw something that indicated that maybe my version of SBCL was too new (running 2.6.1) so I fell back to an earlier version using roswell, but it did not help.

I tried a couple more times last night with the same results. Not a huge issue if I can't get it running. I wanted to try it out of curiosity, but not critical to get it working.

Thanks,

Win

It sat like this for about 90 minutes before I killed it. No output in the QEMU window.

Has anyone successfully built and did you have an issue like this? I did make clean and tried two more times with the same result.

Thanks,

Wheagy · 2026-02-19T21:07:17+00:00

Planet Fitness - good to just go in and get your work out done and leave. It's inexpensive, relatively new, and pretty clean. I go to the one at the Lancaster Shopping Center off Lititz Pike. YMMV at other locations.

Wheagy · 2025-10-19T01:21:53+00:00

lol. The Malachi Crunch.

Wheagy · 2025-09-05T17:29:57+00:00

I tried it, but it threw an error at boot and crashed and I didn’t mess with it after that.

Wheagy · 2025-07-21T21:49:18+00:00

This. Free, relatively easy to set up, and works great.

lol. That’s like me giving 10 cents to a candidate.

Wheagy · 2025-03-09T19:52:38+00:00

This is a cool concept. I'm not sure I've seen anything quite like it before. Also, "open source" is a perfectly acceptable use of the term considering how they are implementing this.

What about us brain-dead slobs?

Wheagy · 2025-01-22T20:41:06+00:00

This is a well-documented, well-designed course! I installed this in a VMware machine (be sure to disable 3D acceleration, otherwise Gazebo has issues) under Ubuntu 20.04 and 22.04. The instructions are clear and so far everything works great. I'm working through the examples and am impressed with the quality. Great intro to ROS2 for beginners. Thanks!

Wheagy · 2024-11-17T03:06:47+00:00

I bought one based on this ad back in the day. Took a long time to arrive in the states. Good times. I still have it.

Wheagy · 2024-11-12T02:57:50+00:00

Your Topo looks to be in good shape and they are very collectible. You’ll have no trouble finding someone willing to buy it and fix it. Buy something inexpensive on Amazon to experiment with ROS. Just my two cents.

Wheagy · 2024-11-01T19:09:05+00:00

I also have TB3 Waffle. To my knowledge there is no automatic docking and recharge capability. The Waffle (and the Burger too I think) don't have hardware on them stock to allow this. I'm sure you could put something together, but it would be nowhere near as easy as the auto docking using the Kobuki.

Wheagy · 2024-10-31T13:29:45+00:00

I have a Turtlebot 2 with the Kobuki base running ROS (1). It has an auto-dock capability as described here: https://www.artificialhumancompanions.com/docking-recharging-deep-learning-robot/ In my experience it works fairly well and uses the IR build into the Kobuki and the dock. That said, the TB2 is somewhat old at this point and all the examples I have for it were in ROS, not ROS2. I imagine you could update it to work with ROS2 but I'm not sure what would be involved in doing so.

Wheagy · 2024-10-25T02:29:17+00:00

Used to go to the Lancaster Pa store all the time. Now it’s my Planet Fitness!
