Notational Velocity [0] seems to be something very similar, if not the exact same, except it's a macOS app and not a web app. [0] http://notational.net
thanks! Longtime user of nvAlt and I never noticed that.

That's hard for humans too. I think we need to give up on the idea that fully autonomous driving will be perfect.
I'm obviously talking about matching human performance and this is the hard problem

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5552051/ > We have previously shown that 207-nm ultraviolet (UV) light has similar antimicrobial properties as typical germicidal UV light (254 nm), but without inducing mammalian skin damage. The biophysical rationale is based on the limited penetration distance of 207-nm light in biological samples (e.g. stratum corneum) compared with that of 254-nm light. Here we extend…
So if I'm reading correctly, the 207-nm ultraviolet light simply doesn't make it past the outer (dead) layer of skin.

I use it every day. With wifi-direct there is zero lag. I work with 3 1440x900 virtual screens. It’s more than enough for coding and the convenience of multiple screens for free offsets the low resolution.
Did you try increasing internal texture resolution? It makes text crispier. The framerate will drop, but it's tolerable for this use case. I find it very useful. There are various resolutions supported, this is the highest where increase in quality should be most noticeable: $ adb shell setprop debug.oculus.textureWidth 2048 && adb shell setprop debug.oculus.textureHeight 2048 You have to start application after this…
Rust lang - Memory safety through zero cost abstraction as a way to eliminate a large class of errors in systems languages is interesting. Especially if it allows more people to write systems programs. WASM - Mostly as a compile target for Rust, but I think this changes the way software might be deployed. No longer as a website, but as a binary distributed across CDNs. ZK-SNARKS - Zero knowledge proofs are still nasc…
> RoamResearch - The technology for this has been around for a while, but it got put together in a interesting way. Just checked out the website, how is it any different from Dynalist or Workflowy?
Workflowy is strictly an outliner. It's like Gopher--hierarchical, unlike the Web, which is a graph.
Feature-wise, Roam is more like a graph. You can really easily link to other concepts, and rename pages (and everything renames). It also has a page generated daily, for things you want to write down.
Feeling wise, you get to write things and collect them and organize them later. I think it's more condusive to how people think and research. You might have a piece of data, but you're not sure where to put it yet. Most other note taking systems forces you to categorize first.
Optical Coherence Tomography (OCT) occupies a intermediate position in accuracy / skin depth for soft tissue between ultrasound and MRI Optically pumped magnetometers (OPM) approaches SQUID level accuracy without need for supercooled device, can be worn or used as a contact sensor like ultrasound.

I speak up against cryptocurrency because it's a cancer. It's a hype adding to climate change without any real world use case whatsoever.
Most new cryptocurrencies are moving away from PoW because a.) it's a massive waste of electricity and b.) it's not actually secure anyway, because we've seen a consolidation of mining power with major ASIC customers who have cheap power costs (notably in China). Ethereum's moving to it in 2020 or 2021, and EOS, Stellar, Tezos, Cardano, etc. are already PoS or derivatives.
Self-driving cars. Now that the hype is over and the fake-it-til-you-make-it crowd has tanked, there's progress. Slowly, the LIDARs get cheaper, the radars get more resolution, and the software improves. UE5's rendering approach. They finally figured out how to use the GPU to do level of detail. Games can now climb out of the Uncanny Valley. The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU,…

Slowly, the LIDARs get cheaper, the radars get more resolution, and the software improves. Still don't see fully (fully automated) self driving cars happening any time soon: 1) Heavy steel boxes running at high speed in built up areas will be the very last thing that we trust to robots. There are so many…

You could be right. My alternative possible timeline interpretation is that two forces collide and make self-driving inevitable. The first force is the insurance industry. It's really hard to argue that humans are more fallible than even today's self-driving setups, and at some point the underwriters will take note and start premium-blasting human drivers into the history books. The second force is the power of numbe…
This reminds me that Tesla itself is starting to offer insurance, and it can do so at a much lower rate. I assume this is because: 1) Teslas crash much less often, mostly due to autopilot. 2) Tesla can harvest an incredible amount of data from one of their cars and so they can calculate risk better
Does Tesla see when you speed and increase your premiums?
