I am continuing as a consultant with Meta on VR matters, devoting about 20% of my time there.
This is explicitly a focusing effort for me. I could write a $20M check myself, but knowing that other people's money is on the line engenders a greater sense of discipline and determination. I had talked about that as a possibility for a while, and I am glad Nat pushed me on it.
@tom_forsyth You can get false reflections, but those would scan as “walls” to an echo locator, not a mirroring of the environment in front of them.
For animals that use sound to build a world model, there is no such thing as a mirror, but there are probably lots of “audible illusions”. Bats may be too simple to appreciate it, but I bet dolphins have cultural lore around it.
!!!! Ok I recorded a (new!) 2h25m lecture on "The spelled-out intro to neural networks and backpropagation: building micrograd" youtube.com/watch?v=VMj-3S… .
This is the culmination of about 8 years of obsessing about the best way to explain neural nets and backprop.
@bhsharp @antovsky Imgui definitely has the programmer/Linux GUI feel to it, but I don’t see why the model couldn’t be applied to a pretty, modern looking GUI.
something more pleasant, like a loud woodwind instrument? I suspect the best answer is to change the question, and engineer better automated rakes and brooms instead of blowing things around.
I loathe leaf blowers, so I often wonder what the acoustic design limits for a high speed air moving device are. How quiet could it be if the air source was impractically far away, and the business end was just a carefully engineered duct? Could the tone be changed into \
My DGX Station had a pump failure, so I had to use the BMC to gather some data. It is a little creepy talking to a server that is apparently powered off.
@KelseyTuoc I love reading lists. Give me a reading list!
I was amused to see, strapped to a giant power line tower, a box of industrial equipment with… a solar panel on it. It probably makes perfect sense; panels are cheap and universal, but it makes me wonder if there is a way to inductively pull modest power from 345KVac lines.
It isn’t trivial to modify the history of a wiki, but it is easy compared to a blockchain. Arguments for the robustness of a blockchain look good with lots of examples of sketchy changes to conventional historic ledges. I’m wondering specifically about Wikipedia.
In @balajis thenetworkstate.com there is a line about “history as written to the ledger vs history written by the victors”, that made me curious: Wikipedia edit wars are a thing, but the edit history assuages me. Are there cases where histories have been wiped by victors?
The mammalian cortex is more or less a two dimensional structure, but the urge to treat an artificial network as a wrapping toroid is very strong. It may not have any serious advantages, but it feels nice to not have boundary conditions.
I had suggested to Lex that he edit it down to a more manageable size, but we didn’t even cover half the things we wanted to talk about. It might make sense to factor me into independent gaming/rockets/VR/AI phases, but everything winds up overlapping. twitter.com/lexfridman/sta…
@00Core00 I’m not very sensitive to water taste; It taste fine to me. It has multiple stages of activated charcoal filters, reverse osmosis filter, and a mineralization stage for taste. It is basically a food-safe dehumidifier plus a water purifier plus a hot/cold water fountain.
@sysrst Three+ gallons a day in my 45% humidity house. It is kind of noisy.
@PhoenixLumen There are multiple accessories that put batteries in the back. Doing it for the base would increase the price a bit.
I got an atmospheric water generator — I can’t really justify it, but it is neat to be able to channel my inner Tatooine moisture farmer and pull drinking water out of the air.
You can see the colorizing effect of the birefringent stressed plastic on the lid of a Pringle’s can when illuminated by an LCD monitor’s polarized light, but not in normal lighting.
@marjanovicsteva Apple removed all 32 bit apps several years ago, so all of my iOS apps are gone now.
grew out of one of the tiny little teams attending Space Access, @SpaceX is still very much the stuff of dreams, and Heinlein is smiling.
a $100M+ effort, and @elonmusk was the only one that could pull that together at the time. It maybe could have happened earlier if Andy Beal had stuck with Beal Aerospace, but there weren’t any other good prospects. While it would have been poetic if space industrialization \
“Keep learning at a small scale” was not a good plan for anyone. A few years of team building with a suborbital vehicle was probably a good idea, but it should have been “orbit or bust” soon after. I could imagine doing that for $20M with a lot of luck, but it is really \
a profit on suborbital flights; the flight rate and risk profile won’t close for them. A small, scrappy company that accepted a catastrophic liability and image risk probably could have run profitably, but not companies that represent billionaires. \
Many companies were aiming at the suborbital space tourism market. It is interesting to see Blue Origin and Virgin Galactic both spend more money to build that than SpaceX and now others took to make their first expendable orbital vehicle. BO and VG are never going to turn \
