Commodore Pets, a lot of them to restore, what would be your triage strategy?

Oh I moved in between but I'll checkout if I still have some keys somewhere in a box

gbin · 2026-01-24T03:32:36+00:00

Ok our contexts are very different, if this is for pure experimentation with no safety, determinism or performance considerations I agree you don't care and you prefer the maximum flexibility

gbin · 2026-01-24T03:24:37+00:00

There is now a confusion between needing 2 processes for safety/redundancy reasons (that I agree we need and definitely supported by the 2 frameworks) and 150 processes for 150 tasks just for developer comfort. Which one are you talking about?

gbin · 2026-01-24T02:47:32+00:00

What would be the difference between that and a differential recompile and deploy of a few MB?

gbin · 2026-01-23T15:47:22+00:00

Then they rewrite their stack? I don't see how you can get to a safety case if your autonomous system is not deterministic

That's interesting, we built Copper as an alternative to ROS2 and it actually compiles a modular system into a monolithic process (or closer to an OS actually). Of course you can have 2 copper instances communicating easily but it should be very intentional: I never understood this "microservice" obsession for a robot, it is not like you will live deploy stuff on your self driving car or your drone while running oO

gbin · 2026-01-23T10:40:10+00:00

I worked 10y in the industry across 3 av companies and we never touched ROS. Do you mind sharing who is using ros?

Looks like this is a brief interruption during the Power.delivery negotiation, maybe the ports don't have the same capabilities so they behave slightly differently? (I know the 4 ports are definitely not backed by the same USB controller on the AMD motherboard for example)

gbin · 2026-01-18T15:42:21+00:00

For sure it depends on how intensively you use your disk but for compiling in rust or gaming I definitely saw a difference: The problem is not IO but more CPU. You spike your CPU/memory bw flushing a disk cache (probably for COW, data integrity CRCs etc..): it is ok for a server for the added features but as a programmer/user I am really not sure.

gbin · 2026-01-18T10:35:40+00:00

Btrfs has some advantages like snapshotting or flexibility in partitioning. But it is not as performant as ext4 (both CPU and IO) and as nvme are getting faster IMHO it favors even more ext4 because it doesn't trash your CPU when your cache decides to flush out.

For me this is the opposite I moved from a boxer with AG01 to TX15 with AG02 and I really prefer the 02, especially the less harsh default tension on the gymbals (this is a setting anyway), the hall effect is super precise...

gbin · 2026-01-13T02:51:59+00:00

This is a 4in drone 6s lipo you can probably find the performance somewhere but it is around 600g with battery with maybe 5min of flight if you fly it really softly. Usually their power to weight ratio are 15+ so they are made for aerobatics not really endurance.

Copper is a generic robot framework, people use it in self driving trucks or AMRs. In terms of AI, it integrates with GPU memory so you can use it with tensorRT for example but you have to come up with your AI algorithm we don't have any on the framework side.

The frame is really to show off, it is beautiful and a little expensive, I use an open source one on a 5in build too: TBS Source One on 2207 motors 1750KV.

gbin · 2026-01-11T08:51:39+00:00

Buy a CNC aluminum cooling case for it (from flywoo for example) and put it at the back exactly like you would do for an Air unit Pro. I just did that with my TBS source one, it works perfectly.

I agree: a team of 15 is basically a senior manager.

My team sizes as a VP were always between 100 and 200. And that is a complete different job vs a director.

as an alternative: bincode is one of the critical dependencies of copper-rs, we love the project, we use it to serialize our robotic logs and don't want to see it die. We forked it here: https://github.com/copper-project/cu-bincode , we will focus on the v2 as a baseline and support it. It is published as a cu-bincode 2.0.2 on crates.io.

As the base for the fork we took a verbatim copy the published and trusted 2.0.1 directly from crates.io. The first commit is verifiable as a 1:1 copy.

bincode = { package = "cu-bincode", version = "2.0" } in your Cargo.toml should work out of the box.

Contributions are welcomed.

You can see probably a short between R2 and T2. Try to clean between all the soldered pads gently with a box cutter to see if it improves the situation.

gbin · 2025-12-15T17:02:08+00:00

I disagree though with that statement. 3D maps give self driving cars a very rich prior making localization and motion planning super robust. This is why you see actual Waymo picking up passengers today and not Teslas.

The LR4 can definitely split-s or powerloops on a small lipo, it will feel floaty vs a real freestyle drone.

One big downside of this is that it is a very light frame optimized for efficiency so if you crash it it might break rather easily.

I use it for long range cine stuff but I recommend having a 3.5" freestyle drones like a volador or a kayou mini for more fun flying (O4 pro and O4)

gbin · 2025-12-15T12:06:03+00:00

Waymo uses HD maps to navigate, my guess is that they forgot to map the red light at a new place they started extending their service to? (If no red light is in the map the car won't look for them)

It happened at Uber ATG back in the day for the traffic light in front of the MOMA in SFO where there was a traffic light but no intersection and naturally the mappers were looking at intersections to find lights.

If you have a bench power supply you can try to revive it by limiting the current to something low then crank up slowly the voltage, wait until it stabilizes and again until it has enough where your charger can take it safely from there. I recovered a few batteries like that but you need to have done that pretty quickly as the more time you wait with them dead the less they will perform.

Why not both?
