I wonder if there is a way to fund and scale a service that uses a browser addon and separate database for reviews. People already use Honey for discounts, Keepa for historic pricing, and fakespot fo…

Tax money. You get what you pay for.

That's the one! From the conclusions: "A (positive) net health benefit emerges only in dangerous bicycling environments under optimistic assumptions as to the efficacy of helmets and a mino…

I once read a convincing argument that, in some cases, American's resistance to helmets caused helmet laws to have a net negative effect on health. The author claimed that the laws caused enough…

Interesting. The NYT says: "Each kit, which tests a single swab sample, is expected to cost about $30 or less, said Bella Zabinofsky, a spokeswoman for the company." So it sounds like a one…

The test is made by Ellume. Here is their press release about the approval: https://www.ellumehealth.com/2020/12/15/fda-authorizes-ellum... Here is the product page: …

Makes me think of Oklo: https://en.wikipedia.org/wiki/Natural_nuclear_fission_reacto... …

"Corrosion is a natural process that converts a refined metal into a more chemically stable form". Oxidation is the most well known form of corrosion, but there are many other corrosive reac…

For many of the same reasons that Spacex is using it for their starship. It's cheap and readily available, relatively easy to work with, and very well studied. There also really are not that ma…

There are a few reasons, but the biggest one is that ceramics and composites also react with the molten salts. One study from 2015 (1) showed that even testing the corrosion resistance of metals was …

To the best of my understanding, one of the main reason that MSRs have not gone to market is that the salts are so corrosive that containment over the long term is not currently possible. Note the qu…

I often find myself in the same situation. A few years ago I started just putting in "whywouldisignupidontevenknowwhatimlookingat@notcomingback.com" or somesuch tailored comment. My hope i…

Having worked at a startup who's product was built around unity, that 2nd 80% is a killer.

The problem is, OP already did this. So did I. How much in-fighting is there at google that they couldn't just port over the data? Right now I'm pissed that Google tv doesn't have a w…

I still cannot get over the fact that Chappelle workshopped some bits on his most recent SNL opening monologue.

Makes me think of this West Wing opener: https://youtu.be/fAgZVVn_rYg?t=195

I still think that Elon's dream goal is to put a boring machine into a rocket and build subsurface habitations connected by hyperloops on mars.

The latest NPR Indicator podcast did a good job covering this: https://www.npr.org/transcripts/934251081 …

Google 'subsidizes' some of their services by leveraging them to gain valuable information. Google voice was used to train their voice analysis algorithms. Recaptcha has been used to trans…

My first though when I read about this was that it would be a mess for first responders. Fire depts across the country have had to retrain on how to handle electrical car fires. How are they suppose…

Google Keep fans are already freaking out: https://i.redd.it/fyildc8gfov51.jpg

I'm talking about excavators, not fork lifts. Earth movers. There are many jobsites where the only people on the ground are spotters. My friend was a spotter when he was runover by an excavato…

A friend of mine is permanently disabled because of poor communication between excavator spotters. Had the ground not been soft that day he wouldn't have survived being run over. I definitely w…

I would love to see some mock-ups of orbital patterns for a moon based starlink-like network. How does the relative lack of an atmosphere affect things? How large of a constellation do you need when…

Somehow my FIL has managed to setup his phone to not only always share his location with me, but to also alert me anytime he starts a google maps navigation. I get both a gmaps alert and an email eac…

Big fan of the channel. I was looking at buying a high speed camera for work and emailed Lauri for advice. He had reciently put up a video comparing the budget friendly Kronos camera to the much mor…

I've been obsessed with technology that skirts religious laws for a while now. Whole house pneumatic systems to run $800 dollar non-electric blenders. Elevators that spend the sabbath atomicall…
