There is a neat solve for the thermal problem that York Space systems has been advocating (based on Russian tech)… put everything in an enclosure.

Short version: make a giant pressure vessel and keep things at 1 atm. Circulate air like you would do on earth. Yes, there is still plenty of excess heat you need to radiate, but dramatically simplifies things.

This seems to be a way to identify and create a 'periodic table' of different machine learning approaches... importantly identifying 'gaps' between approaches which may yield new ways of doing various learning techniques.

Honestly, and I feel like a promoter… but get either a hackpack from Mark Rober or as otherwise mentioned, mindstorms from LEGO.

As someone in the industry (I literally can call myself a Robot Master having a Masters Degree in Robotics), these simple “kid kits” are phenomenal. When you first start out, the hardest part is knowing the hardware is actually going to do what you tell it to do. Simplifying the mechanical engineering/electrical engineering so you can immediately create real world actions makes a huge difference in giving you motivation to keep going.
Once you have the basics in place and you understand mechanisms, sensors, and some algorithms, you can move on to other parts of robotics.
However, keep in mind robotics is really about system thinking… you have to understand trades between sensing, thinking, and acting. But most importantly you have to remember you are dealing with the real world… you can’t as easily write a unit test and know that a particular actuator will behave exactly the same way every time.

They don’t… just do whichever one you are most interested in doing. Each box more or less stands alone (at least that is what I am observing from my kids assembly of them)

My kids have loved watching Mark Robers videos, have the subscriptions (one of both the backpack and crunchpack), and we uploaded our video for SatGus.
If you have young kids (6-15) these are perfect educational tools. Highly recommend. Only downside is some of them are a bit “mischievous”. For example a “Bobbie trap” that launches balls at whomever tripped the wire. Good times…

This has been a pain point for us and our development process… not all versions of Nvidia drivers are the same… even released ones. You have to find a “good” version and keep to it, and then selectively upgrade… at least this has been the case the last 5 years, folks shout out if they have had different experiences.
Side note: our main use case is using cuda for image processing.

Just to plug a friend… Velo.ai does similar things… but has other stuff going on: https://www.velo.ai/
Interesting to see how these two would compare, but my first (light) glance points to velo.ai being further along…

It seems to me that if SLS goes… so does Gateway. That said, one thing to note: There are not that many stable lunar orbits. Unlike the earth, the moon is very lumpy. It is the reason why most lunar orbiters end up doing a planned crash as their end of (relatively) short life. From that standpoint, orbits that are a bit further out are much more appealing to have relatively low delta v requirements.
All that said, once Starship is regularly in use for lunar delivery… I suspect we will have a fundamental new paradigm for space.

Reading this, this line deeply resonated:
“People that out of necessity grow a thick skin with not fitting in and being OK standing out.”
I think this is a pre req to trying to do what a founder is working to do: Change fundamental belief states of the vast majority of people. It is extremely uncomfortable to stake out a position no one else believes in… yet. It requires courage (and thick skin) to get people through the disbelief curve.

They insist likely due to the “Kleenex” effect. Couldn’t find a good reference, but once an item becomes generic, it can loose copyright.
