If you wanted to identify the components of a liquid, could you heat it and analyze the steam?

No. No, it isn't. Lynx is a browser I use in the terminal. This is something else.

I think people who are serious about it run QNX or VxWorks. Most robotics projects aren't serious and run Ubuntu unfortunately.

Can confirm. $DAYJOB makes robots subject to hard worst-case latency constraints. The product runs on QNX.

> They claim to know a lot but then none of them build proper Cf Lumen or F.Lux style tooling (i.e. super easy default instead of requiring tons of setup) for turning ALL blue light off (red shifting) IN THE DEFAULT OS as the primary way to use your device at night.

Probably not what you are aiming for but for Linux this is a somewhat solved problems. The default DM, Gnome, has built-in color shift with a time schedule AFAIK. For Wayland and xorg there are also numerous other solutions that do a display-level redshift, I can recommend wl-sunset for Wayland.

Can confirm https://github.com/jonls/redshift works great; been using it for years.

Those of you who use ROS in production, do y'all use ROS 1 or 2? Do you maintain your own fork? I'm curious how people do this, with the upcoming Noetic deprecation.

You treat it like the metaphorical toxic waste it is: avoid it at all costs. You don't need ROS to get a dependency manager, a build system, a middleware, and/or a process manager.

for a teenager, I definitely wouldn't recommend Ros, unless they're already very deep into Linux, c++, build systems, etc - I'm sure there are kids out there that can handle it, but I'd say most would find Ros endlessly frustrating. I think it makes grown men cry.

robot wise, I'd recommend something they can program with a raspberry pi and python, if they have some light background in programming. I had a quick look on Amazon and I have no affiliations with these, but maybe look for something like this: https://www.amazon.co.uk/FREENOVE-Raspberry-Tracking-Avoidan...

note this one doesn't have either a raspberry pi nor any batteries. you might find a better one.

Can confirm. I am a grown man and my professional work with ROS has made me cry.

Last time I used ROS, it forced you to use its build system. Catkin or something? It was a layer on top of Cmake.
rubicks · a year ago
My colleagues and I used to joke that any build system issue you encounter will be addressed in next year's build system.

* https://docs.ros.org/en/jazzy/Tutorials/Beginner-Client-Libr...

It doesn't feel like a joke anymore.

I tried to use ROS2 twice in my professional career. Both times ended up with massively bloated build pipeline code, significantly longer build times, and massively bloated Docker images.

Don't use ROS2. The benefits just aren't worth it. It's great for school but it's terrible for production.

I have worked in two failed and failing startups that invested heavily in ROS. I could fill several volumes with "ROS Gotchas". Everything in the ROS stack is either a useless curio or an on-fire clown car.

Using ROS is a great way to turn your project and business into a cautionary tale.
