#352I'm growing the freshest lettuce, iron-rich kale, and a lot of other leafy greens! While in college (CS & Math), I got heavily interested in growing food in the most efficient and healthiest way possible. I was a dreamer when I started so I thought more of how to grow 'earthly' produce on Mars, but then I realized that my own planet Earth is so massively underserved. It's basically like this- I mastered growing leafy…

#354I'm helping to build a scalable system for delivering high value and life saving medical supplies to hard to reach places via autonomous aircraft. The system is currently operating in Rwanda and Ghana, and aggressively expanding over the next couple years. Specifically, I spend a lot of time thinking about and writing embedded software. The aircraft is fully autonomous and needs to be able to fly home safely even aft…

#355We're trying to improve the security of the Internet by replacing Certificate Authorities with a distributed root of trust. DNS is currently centralized and controlled by a few organizations at the top of the hierarchy (namely ICANN) and easily censored by governments. Trust in HTTPS is delegated by CAs, but security follows a one of many model, where only one CA out of thousands needs to be compromised in order for…
With CAs and domain registrars it's possible to verify your identity through other means if you just forgot your password to access their database directly.

#358Dental treatments, besides being very expensive, are often (up to 28%) unnecessary. This happens because no-one keeps dentists in check. I am trying to make dental treatment and diagnosis reviews easy, cheap, reliable and fast.
I’m actually a dental student myself, and it saddens me that a significant chunk of dentists take advantage of the of the self-policing inherent to the field. It generates generalized distrust and resentment among the rest of dentists, in addition to being simply unfair.
As far as I know, there are no diagnosis codes in dentistry, just treatment codes. If it were, I imagine it could be possible to prevent this problem by randomly and routinely validating patients charts.
On a side note, it is a budding dream of mine to build a start up related to dentistry, particularly in the realm of dental informatics, but not limited to it. I was wondering if you would be willing to chat with me about your experience sometime. It sounds fascinating.
Thanks again.

#359I'm building an AI agent to help develop foreign language skills through realtime (spoken) conversations. It's funny how we're all working from different definitions of the word "problem" - I'm certainly not changing the world with medical supplies for developing countries, renewable energy, payment systems and so on. But it's something I'm really passionate about, and I'd be over the moon if I came anywhere close to…
