I've come dangerously close to starting a shadowy organization at my university for the sole purpose of maintaining and operating a couple DIY book scanners.

SuperHot VR is pretty close to a killer app for me. Cool mechanics like that scaled up could definitely keep me interested - I burned hours and hours on my roommate's PSVR last Summer exclusively playing SuperHot

By my reading, the center core was using three engine burns for more efficient boost-back and re-entry burns. The side cores and typical F9 boosters (afaik) always use single engines for those and occasionally three-engine burns at landing,

Why is the story about investing in 2009-2011 in this post? Unless they invested right in 2011, and your benchmark for "impatience" is investing in late 2007, their accidental market timing probably lost them money. Plopping every

I think you're closer to our root issues than most of the comments, but there are still links further down the causal chain from here. College admission is hyper-important and hyper-competitive today because life is hyper-competitive

The roughly equally bad take on that sequence is that after confirming you're neither balding nor impotent, it assumed there was someone in your life to purchase Victoria's Secret for .

OK right, you can't restrict ownership. Would it be legal to simply grant extra rights to owners who adhere to the LTSE's rules? Ie, one share carries 1 'point' of voting power, unless the owner is an individual or an en

Nowhere near a lawyer here, but: Would it be possible to contractually obligate any entities holding these stocks to also adopt tenured shareholder voting power? Doing so would certainly improve the loophole situation, though I suspect it d

The quoted top speed for micrometeorites has to be wrong. Perhaps missing a 0? 45 mph is silly low, there's no way Martian atmospheric drag could slow them that much, let alone the case of the moon.

The time stamp is handled on receipt of the hash by third parties in my mind, not by the originating device. Ideally the position component of the data would also be verified by 3rd parties, eg cell towers receiving the data add their own s

This reminds me of a crypto application I've been waiting for someone to build / explain why it would suck: Secure enclave based verifiable recording devices. So, a camera that uploads a signed hash of every image it takes using m

A couple points: First off, in the 'backup' argument Mars isn't meant as a bomb shelter for the human species. It's a shelter for human civilization, which is a higher level and much more fragile thing. Think about the l

Fair criticisms, but I maintain we're going to end up tracking our food eventually. It's just going to get cheaper, and there are real upsides IMO. Wrote this because I got in a similar conversation on twitter: https://

The trouble is, I've always thought Juicero was a bank shot for digitized food in general. If that's the case, they needed to be serving consumers not businesses. The concept of food that's uniquely tagged and tracked from or

Thanks for the catch, I wrote that comment a little too flippantly and left out important factors, the motors/regen alone certainly don't get you there. Adding in the reduced drag of levitation vs soft tires combined with central

The energy required only grows quadratically if you stay on one technology. Simultaneously switching from internal combustion to linear electric motors with efficient regen. braking and bumping the speed up 10x turns out to be a wash.

This is too out there to predict with any hope of accuracy, but I suspect/hope planets will have a sort of anti-MAD, mutual perfect defensibility. Orbit is a very offense-biased environment. It's much easier to hit a ship / m

I think your first argument about sustainability has a key issue: An enormous proportion of Earth's current issues are historic in origin. The population explosion is a result of rapid development in SE Asia and Africa - developed soci

We can't meaningfully speculate about what such a war would look like, technology will advance too much before then. I don't think it would be nuclear though. Nuclear bombs are delicate devices, the only reason they work on Earth

The lack of a magnetosphere is less of an issue than popular science claims it is. The current atmosphere weighs about 25 terratonnes[1] and MAVEN estimated solar wind is removing 100 grams/sec[2]. That's an annual loss rate of 0.

One thing I've always been curious about with ultra-resolution stuff like this: Is there a substantive difference between editing in 8K and in say 720p? Ie, could I edit my whole movie in downsized resolution, save all the transformati

Beef and pork are significantly worse than seafood in terms of environmental impact. There's nothing to celebrate in the sources of American protein. If America was as hungry for seafood as East Asia, fisheries would have depleted enou
