That's exactly the type of project I'd like to be working on -- embedded programming that literally saves lives. Thank you for sharing. Your path to where you are now is crazy...sounds like you've had an exciting career!

I didn't know I wanted this until now, and now I really want it. I often open a ton of related applications, and then avoid restarting my computer because it's incovenient to reopen everything. I'm on Linux, so I won't

This is anecdotal, but I remember reading an article about a dentist who was convicted of doing expensive and completely unnecessary surgeries on many of his patients, to the tune of hundreds of thousands of dollars per patient in some ca

As some of the other responses mention, this is an insanely complex problem...as evidenced by the large number of businesses in this space. In your eyes, what are the best flight search engines at the moment? Aside from https://w

Do you have a website? Public policy is an area that seems almost ridiculously unoptimized, so I'm really interested in any organizations that are trying to fix that. This is the first time I've heard of doing research with the ex

That explanation was surprisingly accessible, thank you! It also blew my mind. I'd never thought of the building blocks of the universe as forming a hierarchy before, although in retrospect, it feels obvious. Were you being literal whe

Fascinating. I'm going to have to do some reading about this -- it's a whole world I didn't know existed. Thanks for explaining.

That's a really worthwhile problem to be working on. Kudos to you. I'd be gutted if something like that happened in my area, although I'm lucky enough to live in an area that's mostly trees.

Agreed, the differences between municipalities makes this really hard to scale. If data providers like the ones you mention don't exist, the two ideas that immediately come to mind are a) becoming that data provider (obviously), or b)

I won't pretend to fully understand this, although I do understand the basic theory of higher-order hyperoperators. I'm curious, though -- where/what are the applications for this?

I've actually been thinking about the issue of energy storage a lot recently -- I've read a ton about how lithium-ion battery production is exploding (usually not literally), but it seems unreasonable to store enormous amounts of

That sounds awesome! Are these things you're doing for work, or on your own (or both)? I'm not much of a gamer, and I don't know what the market looks like for Nintendo systems...what are the applications for custom ROMs on D

Thank you for working to fix a problem that would materially improve people's lives. I have a lot of respect for that. Finding a way to have both a technological and social impact in a single project is one of my longterm goals. Homele

That sounds really cool -- I'd be interested to hear more about some of the hurdles you've encountered integrating modern web tech and old enterprise software. Any particularly notable challenges you'd be willing to share?

Kudos to you -- that's a problem I'm definitely not prepared to work on yet!

This is mildly off-topic, but how does one end up working on problems that are complex enough for things like this to even be an issue? It sounds incredibly interesting to me, but most of the software I've worked on has been at least s

I do this all the time! I definitely haven't had a 100% reply rate, but I often finish with something like "I know you're really busy -- no need to respond" when emailing someone I don't know. Maybe I should stop do

This doesn't answer your question about money, but with (mostly) human drivers on the road there isn't much incentive to keep the lines visible, because humans are excellent at inferring where the lines should be, even if they&#x2

Ok, awesome! I'm pretty much an exclusively Linux guy, so that's the path I'm planning on going down -- my email's in my profile. I'd love to discuss further!

While I agree with you that it's virtually impossible for humans to use up the uranium in sea water at our current energy consumption rate, I think it's worth thinking about that if we had "unlimited" energy, we might us

This looks amazing, thank you! A few posts up, melvinroest suggested starting a study group for the (Windows-based) course in the original post -- would anyone be interested in doing the same for this Linux-based course?

Until recently, I agreed with you, but I just read a book called Quiet (by Susan Cain) [1] about introversion, and in the book they give evidence that shows that many of corporate history's most successful leaders were introverts. I hi

While my knowledge of IPFS is pretty basic, this strikes me as a great use case for it. IPFS ( https://ipfs.io ) is a P2P internet protocol that's made to enable a decentralized internet...I believe its goal is to supplant (o
