I’m working on Newsy. https://www.newsy.co I have quite a few domain names that I have purchased over the years that I am not doing anything with at the moment. I wanted minimal amount of work to make a good use out of these domains. So I built Newsy. It turns your idle domain into a news aggregator. I’m nearly there. You can sign up and I’ll invite you to check it out!

I like this and all the best. I have access to close to 50 idle domains I will try see how I can put them to use. Is there a way to customize the news such that it is relevant to each domain?

Solving the world's trillion-dollar energy storage crisis. (multi-trillion, actually.) https://www.terramenthq.com/ About a year ago, I started spending more time researching about climate change. I learned how important energy storage will be to enable renewable energy to displace fossil fuels. The more I read, the more fascinated I became with the idea of building underground pumped hydro energy storage. I found a…

Kinda surprised to hear that date, as the UK has a pumped hydro plant[1] which started construction in 1974 and opened in 1984; Tom Scott has a YouTube video about it[2]. It's not all underground, but the machinery is built into a hill and it pumps from a reservoir at the bottom up to the top when electricity is cheap, and is used as a fast-startup generator when demand is higher. Is it really more feasible to build the upper reservoir underground, than on top of, somewhere? Surely "on top of" is higher, easier to get to, easier to flatten, and much cheaper?

Still thinking pretty loosely about the trust space, but a few conclusions on my end: LinkedIn is frustrating because people connect even though they don't know each other very well. I spend a lot of time meeting up with strangers (Craigslist, meetups, dating) and generally hoping that the world is good (though it pretty much always turns out to be). Phone number seems to be something that people only exchange when t…

Hmm, similar thoughts but less about trust and more about the psychology of personal networks. I'm interested in what value we place on connecting people in our network. Say you meet two persons in your travels that might benefit from being connected. What value do you place on making this connection? How does it make you feel? Does it have to have an obvious personal utility? These are the types of questions I would…

I’ve been prototyping in this space as well. Let’s all chat. Ping me at my hn username at @doerhub.com

I'm trying to bring light-fields to the masses, as the next level of VR immersive experiences. I'm building a cheap light-field video-camera and the software to process it automatically and reproduce the videos with a VR headset. BTW, not it's not just like a normal VR video because you have parallax.

This problem will only apply to very few people. But over the past 2.5 years I've been tracking everything and deriving insights on my activities. This produced some astounding results. e.g. Chewing gum makes me more comfortable in a conversation. Recently I've found a community of robot-like people on reddit who also do this. So I decided to build a platform. It's still in its early stages but feel free to check it…

I’ve been thinking about this as well and even got bodmark.com to push out a prototype. (body benchmark) Let’s chat and maybe even collaborate.

Seeing if mental health crises can be predicted by gathering passive data from your phone. ( Accel, gyro, GPS, music choices, keyboard entries, app usage, sleep, facial expressions etc)

i think we’re doing this already arent we? at least foe AdHD and depression. i think its a great use case but the privacy risks are massive.

Wait how are we doing this for ADHD?

How do you deal with occlusion? I had the impression that’s the main issue with VR video, unless your recording rig has a massive horizontal offset to capture the sides.

Characterizing the effect of near-surface humidity and wave action on Ka/Ku band satellite transmissions from a surfboard-sized autonomous swimming vessel. I have a little sensor platform, and customers that want it to do a whole lot more. Bandwidth can be hard to come by 6000 miles from the nearest human.

Semi random question.

Is this related to the refractivity of the near surface atmosphere above the waters surface affecting directionality and bandwidth?

We are working on how to match engineers with engineering teams based on the work environment and team values/culture. I've had too many friends and family members end up at companies that were not a match and watched the massive stress pile up. I want to help people find the right team/culture for them.

Sounds interesting, I always like to see good ideas in the hiring space.

How do you differ from something like https://www.keyvalues.com/

Interesting idea though I didn't see any examples of what that looks like on your website or links to live sites doing this.

Hard to think about it just in my mind with no visuals.
