Oh wow TIL ESP32 can run TensorFlowLite. Person detection in 54ms! https://github.com/espressif/esp-tflite-micro?tab=readme-ov-...


From their homepage it seems they do screensharing + AI summary of meeting.




Reminds me of the Youtube Guy who homebrewed a gene-therapy to treat his Lactose Intolerance, successfully

https://www.youtube.com/watch?v=aoczYXJeMY4


"successfully"

God only knows if he's introduced a carcinogenic gene mutation, or if the effects will last. This is the exact thing proper studies examine.


If he prefers to live his best years lactose tolerant and die earlier but having lived the way he wanted as opposed to living a mediocre lactose intolerant life for longer, then it could still be a success


Effects wore off after 18 months I think. He explains in the video why it was expected.

He took the pills 6 years ago still not killed by cancer. And of course this is n=1. The first thing he says after taking the pills is "Lets hope this does not kill me" :D


Thanks for sharing your product journey. Making hardware products is very interesting, when a single guy does it.

Would you mind sharing some of your prototype to production journey?

- How did you find companies that make the parts (pcb, enclosure)?

- How do you assemble all the parts (do you do that yourself or did you find a company to do that for you)?


> - How did you find companies that make the parts (pcb, enclosure)?

For the PCB, it came down to who could meet the specs that I needed for the board. I recall the three important specs being BGA pad spacing, wire thickness, and wire spacing. The ICE40 was the aggressing chip IIRC. I ended up using nextpcb.com.

For the enclosure, I think I just Googled some and had 3 different manufacturers make the same enclosure, and chose the best one to mass produce. I ended up using mfgproto.com.

> - How do you assemble all the parts (do you do that yourself or did you find a company to do that for you)?

For the PCB, I had NextPCB do PCBA, except for the BGAs (which I soldered myself, 500 of them!) and motion sensors, because I didn't trust mailing my high-value stock to China during Chipageddon. That was likely a mistake -- in the future I would have them assemble everything, because their process isn't designed for how I wanted to do things, and soldering that many BGAs sucked.

For the final assembly I did everything by hand (insert PCB into the enclosure, screw in PCB screws, connect battery, add battery shims [to prevent rattling], add RTV gasket to the backplate, screw in backplate screws, add lens adhesive, focus lens while streaming images). It's a ton of manual labor!


Feels like science papers need a comment section. Replace peer-review with public-review. A way for authors to interact with the larger (science) community.

https://www.papertalk.xyz/ was on HN Frontpage but seems to not have gained any traction (yet).

Maybe arxiv should consider implementing it or integrating with some 3rd party?


I strongly agree!

alphaXiv (https://alphaxiv.org/) is a discussion layer on top of arXiv, and it's starting to gain a lot of traction.

You can replace the arXiv URL with "alphaXiv" to get to the discussion: https://arxiv.org/abs/2404.16710https://alphaxiv.org/abs/2404.16710

Disclaimer: I'm currently helping out with alphaXiv -- it's a fun project out of Stanford


Openreview is nice. I guess it could integrate with arxiv to allow preprints but someone needs to pay for moderation if we are to keep a high standard of comments.


That’s a great idea. In a way, HN is that for many papers in topics that the HN community resonates with

Are there other communities that also post scientific papers and comment publicly? Even if the community isn’t exclusively about science?


One of the sites has a fantastic landing page: https://needle.tools/ (you scroll through 3D scenes)


the marketing is indeed super slick, in terms of added value for the framework, as needle is built on top of threejs, I'm not sure I'll bite


I only skimmed the landing page but it seems like it helps more with the while pipeline (asset creation, packing and optimising) rather than just the end rendered.


I admit it's really cool, but it's not a good fit for a landing page IMO. Would be great if it was behind a "demo" button or something.

Though maybe I'm not the target audience.


And I hope we will have good AIs running on our own hardware. I obviously want to use AI to create lots of porn for me. And that is really no one else s business.

Speaking of - I already heard of a project that is fine-tuning StableDiffusion to produce porn.


How do they have sooo many employees. They are running a few websites and a bunch of apps. I can understand how they would need a hundred people for that. They have a massive userbase. So I can understand how they would need a thousand people just to deal with tech at scale and support.

But how do you manage to have so many people that you can fire 10k ?! If I googled well, they appear to have 72k employees. Where did you find the management that thought having 72k employees is reasonable to operate a bunch of websites and apps ?!


So they are using sound waves to form very exact force-fields in 3D. But when you throw matter in there, would that not interact and reflect all the waves in unpredictable ways, destroying the very exact force-field pattern they are trying to achieve?
