Yeah, we should probably not do this in LEO, where orbits decay and half of the potential acceleration vectors lead back down to Earth. Fortunately, it takes a lot of energy and precision to de-orbit anything heavy that is in geosynchronous orbit or beyond.

If the fissile material could be acquired by asteroid mining, then it would never need to pass through the Earth's atmosphere. I know that still sounds way out there, but I think that uranium or thorium would actually be a great material for kicking off asteroid mining. A small amount will pay off in a big way, it is a very dangerous thing for humans to mine on Earth, and, like the parent mentioned, we really don't want to fly it around where it can fall on us.


In a small toroidally shaped universe, your radio is also your memory. All emissions eventually return to their origin, but you can reorder memory transmissions by moving while the data is in flight.


Wow, just thinking about C++ while slacking, was enough to inspire a solution to a race condition in my Clojurescript project.

Earlier, I made some notes and walked away from the problem, because it was getting frustrating. Then, while I was checking this out, I started thinking "Imagine how complex this would have been if I had done it in C++" Then the immediately following thought was "Well, in C++, I would instead build it like so, because it needs to be thread safe." Problem solved, obvious-in-hindsight solution.

Even though my problem wasn't caused by a low level threading mistake, thinking about the problem in the context of a more primitive tool helped me to better understand how my own tools are working.


The missing back story to Apollo 18!


I thought that it was going to log transactions to a blockchain, as a sabotage-resistant backup strategy.


Yeah, but a good weld is stronger than the metal around it. Win!


Docker. I need/want 64gb in my next laptop, so that I can run deployment simulations.


I figured there was a use case for it. The price for a laptop goes up exponentially when one of its resources reaches an upper limit. But keep in mind that for that price you could build three desktops with the same RAM and run CI/CD on a redundant distributed cluster (which become necessary for long running simulations, unless you want to keep your laptop at the office all weekend). It's also a more realistic simulation due to system resource and interconnect bottlenecks.


DNA is already digital.


Dude. That redirects to a picture of a scrotum in a cup, if you arrive with an HN referer header. I'm guessing you got pranked, lol.


No, I forgot JWZ did that. Sigh.


They could do it in ASCII, on IRC.
