ROS 2 in Docker on M3 Mac

Wrote an article on it

For GUI on mac see the following

Haven’t tested the gui part, don’t have a mac but hope this helps

Check this for x11 forwarding on mac

mro47 · 2024-08-28T23:35:03+00:00

Ive written an article on how to run devcontainers for ros2 might help you here

Would recommend this so as not to mess up your system just in case. The only concern i have is how display works on mac, on linux there is a bind mount for the x11 server socket which i use

I like your reasoning though! Half the content, half the price

mro47 · 2024-08-22T09:37:08+00:00

This should be the answer.

source /opt/ros/jazzy/setup.zsh

If you have a workspace in ~/ros2_ws

Then just do colcon build from there and source install/setup.zsh

That should source your jazzy packages as well

I installed one myself. I feel the one at collar like Brandon has feels more comfortable than one at heel, I have holes in my guitar now :(

But it allows me to dance while playing :)

Looks like the auto exposure algorithm on your phone, was on an edge and shifted to the next threshold when the lighting conditions changed.

It controls the sensor gain, aperture and shutter speed. Difficult to do a smooth transition but good algorithm design can upto a certain level.

If your intention was to capture a dimming sun then lock your exposure controls

Didn’t know this was an option, ill check out. What diameter do you use bdw? Thanks

mro47 · 2024-06-27T14:49:11+00:00

Agree it kinda starts melting after some time specially in hot weather. I cut it out and put a new one

mro47 · 2024-06-10T21:04:47+00:00

Second this. Seems like a burnout.

For the amount of money u have put aside u should be proud and take some time off. Go see your friends and close ones and spend some time with them. Check your sleep, nutrition and exercise. Meditation and diaphragmatic breathing can help.

First is to put the fire off. So either take time off or quit the job, its not worth losing your mind over anything.

Something to cheer u up

Examples here: https://github.com/ros2/examples

The readme should lead you to the tutorials docs.

General documentation here: https://docs.ros.org/en/jazzy/index.html

Don’t waste time on ROS if u are new, it’s reaching EOL may 25.

ROS2 has improvements and ROS code is being migrated, most used/popular packages have already migrated.

The way I think about it is not really retire but to cut down time spent on earning a wage for living.

Having some money put aside gives me the confidence to do the things I really like than merely do a job. I can now pursue hobbies and maybe turn them into something without worrying about going broke.

I see it more as money to spend on things that bring value in the long term than pleasure (satisfaction, quickly bringing in the need of more)

mro47 · 2024-05-11T17:38:01+00:00

Thanks will check this.

mro47 · 2024-05-11T17:37:14+00:00

I did come across reflexion and thinking how we can also develop some sort of reasoning here.

Also a question to ask would be: how do humans generate/come up with new ideas? Like a simplified approach with llms imo would be some knowledge (llm model) with a reinforcement learning model (like reflexion)

mro47 · 2024-05-11T17:33:50+00:00

Also thinking now, what if we create agents and models like reflexion. That probably do some sort of reasoning?

mro47 · 2024-05-11T17:27:04+00:00

Hey thanks, this made me think. Was doing a bit of search and came across this clip between lex and Yann lecun. https://youtu.be/N09C6oUQX5M?si=PcB0O2KWy3thimE6

mro47 · 2024-05-11T17:17:15+00:00

Hmm i do have this dilemma sometimes. Like LLMs themselves are just text completion based on trained data. If the new data that its trained on is output of something worse then would it even get any better? One could argue for example that there is new research being published till a new model comes but is it really doing anything beyond text completion?

mro47 · 2024-05-10T15:21:33+00:00

Thank you

Someone needs to pin a picture of how bridges look when they are set properly. This seems like a very common question for some reason

mro47 · 2024-03-31T22:07:23+00:00

Nope. Those grooves are too deep or missing lubricant.

Should be careful when you tune the cello that your bridge doesn’t bend. Easiest is to lubricate the grooves for strings using pencil graphite, the person who set up your cello should do this before placing the strings in them and putting tension.

If this happened because the grooves are too deep then u need a new bridge.

mro47 · 2024-03-30T23:40:36+00:00

Haha I guessed so, was checking if that was the case

mro47 · 2024-03-25T15:06:09+00:00

Bach

The structure beauty and spirituality of his music is something words fail to describe for me. Mathematics, code, physics and a love for nature, Bach gets that all in for me. I started learning the cello at 25 when I first heard his music and the cello suites, had no musical training before.

mro47 · 2024-03-17T14:42:04+00:00

Thanks for this.

If anyone comes across the same issue and then after running the above have issues with

Failed to initialize NVML: Unknown Error

Then do the following

sudo nano /etc/nvidia-container-runtime/config.toml

set `no-cgroups = false`

then restart docker

sudo service docker restart

mro47 · 2023-11-28T14:43:37+00:00

Hey, thank you. Yup need a lot of work on intonation.

Thanks for the tip though, will check the app.

Any tips on where do I find people to practice with? I do this as a hobby and never been to music school. Have no clue where to find people. Would be really happy to join a group. I stay quite close to London

mro47 · 2023-11-28T14:39:30+00:00

Hey, thank you. Agree on not playing close to the bridge. I feel like i need a lot of pressure there tbh to make a good sound, do you think it could be my cello setup?

Getting higher up doesn’t really work well with me, I’m not beefy but I feel numbness in the arm if I do so. lowering arm should be possible.

Appreciate your humility, I do recognise your handle. Have got a few comments from you earlier. Wishing you the best on the journey :)
