ROSCon 2025 in Singapore is a wrap, and I am super happy to not have to do any work for a few days because it was a lot of preparation.
I've written up a blog post with my experiences to share with all of you:

I have a hard time dealing with people who make you feel bad/stupid for not knowing something they do -- whether intentional or due to poor social skills.
As someone in tech, I should have already become desensitized to this, but I guess you can't just change how you feel.

Doing a whole bunch of OSS pushes pre-ROSCon. I'm psyched up for now, but definitely looking forward to the break after the conference.

Absolute dumpster fire of a day. I've tried to do too many things, none of them exciting, I didn't do a good job at any one of them, and I'm too tired to form a coherent sentence.
Sometimes you just need to take the L and try again another day.

I'm excited about this release because my feature (Viser visualizer) is included, plus there are a lot of fixes (especially to mimic joints) that came from issues I ran into myself. Open source is great.

Such a weird positive feedback loop of people needing to signal themselves as pro-general purpose humanoid hype as possible, so their peers perceive their work as still relevant.
Let's remember we're here to solve problems and/or uncover new understanding.

Does anyone know any experts in VR with an interest in immersive video streaming for teleop applications? If so, shoot me a note. Thanks!
