The question is not about how many people use Gmail - and that still doesn’t take into account corporate users. It’s about how many people use the web interface as opposed to using a mobile app.

Yes. And we're both clear that there wasn't always a mobile app version of Gmail, right?

To say that Gmail had much to do with Google’s growth considering that there was only a relatively small Window that email was the most popular form of personal (not corporate communication and spam) and that was over ten years ago before mobile started taking over doesn’t really have any basis in today’s reality.

IIRC Cloudflare Workers run at each Cloudflare PoP, which have higher geographical density than AWS regions, so latency experienced by end-users may be lower.

AWS has the same thing with Lambda@Edge

According to this[0] blog post Lambda@Edge has significantly longer latency (due in part to a smaller number of locations). Cloudflare also uses V8 isolates instead of whole VMs, so much lower overhead. Disadvantage is that you can only run JavaScript and WASM.

> Far UVC lights (200 to ~222nm) OK, these are not safe wavelengths, and whatever you're reading is not right. This is absolutely ionizing radiation. The rate of formation of thymine dimers in this regime is similar to that around 260 nm. That is, it causes DNA damage.

So if I'm reading correctly, the 207-nm ultraviolet light simply doesn't make it past the outer (dead) layer of skin.

The dat website is at dat://aaca379867bff648f454337f36a65c8239f2437538f2a4e0b4b5eb389ea0caff You can visit with the beaker browser, or share it through dat so it won't ever go down. You can also visit it at http://www.nanosavseq.com/ (DNS is not up yet, http://167.172.195.83/book/index.html is direct) It's embarrassingly barren right now, mainly since I've encountered some big problems with getting my DNA quantifier…

The book / documentation is very clean and presented in a fantastic way. May I ask what engine you are using for presenting this book?

mdbook! By the folks making the Rust docs. I love their formatting.

Would you like to work together on this? This is very interesting stuff.

Would love to. Feel free to email me at koeng101gmail.

Genuinely curious, what’s wrong with the lightning network?

Correct, but I’d still like to see their data as to what the impact is to eye tissue.

Mouse-level accuracy requires a well-calibrated setup and the correct size monitor and sitting posture. If you want to do something like a Square POS checkout and need to distinguish a random visitor looking at 4 buttons, it would be pretty forgiving.

Thank you, so not yet an option for me; I doubt my posture and sitting position is regular enough that calibration would work for me. Might, at some point, be a welcome addition to a touch pad though. If you touch the pad and your pointer is far away to where you're looking, jump to the area and do the fine tuning with the fingers.

I already do that without the need of a touch pad, just use your numpad keys as a mouse if you're on windows look into mouse.ahk. Tobii will snap mouse to where you're looking at and senses mouse is moving. Works great when you want to stay on home row, selecting text with it though, not as good.

I think 3d printing still had enormous potential. They are printing jet engine parts with it these days.

when can I print a hamburger? that’s when I’ll know we have made it to the future!

I think something like this is already in the works. But I think the food replicators from Star Trek Next Generation would be better is we had the tech.

> Everyone with a high-mid-range PC already has more horsepower than a PS5 and it’s not doing anything particularly innovative or groundbreaking. The fact that it can stream 5.5gb/s from disk to RAM says otherwise. Commodity hardware, even high end m.2 drives can’t match that. * it’s my understanding that it directly shares RAM between the CPU and the GPU which means way less latency and more throughput.

There are high end drives on the PC market what can match and surpass that, but they are like $2000+ :) Linus talked about that topic last week: https://youtu.be/8f8Vhoh9Y3Q?t=1607

Watching some of that, and doing a bunch odd reading on the PS5, it seems that “some drives” can kind of get close, but the fact that the PS5 physically has custom, dedicated hardware that can directly move data from the SSD straight into shared CPU-GPU memory with minimal input/work from the CPU, and that’s a fundamental architectural advantage PC’s don’t have (yet).

I would sure like to see some architectural upgrades like this in PC/server world though: I’d love an ML workstation where my CPU-GPU ram is shared and I can stream datasets directly into RAM at frankly outrageous speeds. That would make so many things so much easier.
