If you want multi-datacenter consistency, then the best of transaction protocols will still measure latency in terms of the speed of light multiplied by the distance between datacenters.

Maybe you are good at paperwork, but it’s worth remembering that even Google sometimes biffs a domain name renewal. Why put artificial hurdles in front of people who need help?

Even if going gonzo with carbon emissions was fine for the planet, a carbon tax plus basic income would be better than the status quo, for a multitude of reasons.

Makes me feel pretty lucky that I spend an hour a day rain or shine taking the kids to school on my cargo ebike. We all get outside time and I think there are fewer fits from the when riding in the bike’s front box. I have a dual-battery Pa

So maybe the poor and middle class would be better off and the rich would foot the bill?

Slightly OT but I’ve been trying to google this for a while and there are people reading this who will know where I can look: If a government (pretend US if it helps) stopped collecting taxes, and instead funded the budget by printing money

I wonder what the minimum viable terrarium is? The idea that we could keep something sterile will seem barbaric to our descendants.

Not using Facebook isn't a meaningful way to opt-out. The better analogy is not soft drinks, but asbestos or CFCs. All that private information amassed, just waiting to fall into the wrong hands.

It seems like with recent meta-material advances, you could create an object that was a hidden bug, without any hidden parts. Like if you tuned one of those metal concentric ring windchimes just right, it could modulate a radio signal based

One example of #4 that is making headway in production systems is the Calvin protocol (a RAFT based write-ahead-log with lock-free deterministic transaction application). It's implemented by my employer FaunaDB. You can learn more here

Cologne and Copenhagen both have very strong cultures of abiding by traffic signals, even for pedestrians. One time in Cologne I started to feel awkward that we are all waiting, and suddenly a sports car zoomed out of a tunnel and through a

So you can use magnetic field information about a star to learn more about the planets (tidal forces) orbiting it?

One way modern distributed databases handle this is by assuming they can't trust the disks. When you are writing to multiple datacenters it makes recovery from disk errors just another kind of chaos resilience. The Calvin protocol take

Agree. Any activity that is so hostile to other people should be monitored aggressively, and privileges revoked for the slightest reason. By the same token, you should need to file an individual route permit anytime you want to exceed 20 mp

My hack is just fall asleep when putting the kids to sleep and wake up whenever I feel like. If I've been pushing hard, sometimes I'll take all 10 hours, other nights I'm up at 4am ready to work.

Sure. But the point of (early) NoSQL was IO optimization, not logical consistency.
