Most systems I know which require this just do at-least once on the sending side and dedupe on the receiving side. If you build this into your framework, to applications you have exactly-once barring unbounded partitions and the like.

Not sure why this is being downvoted, it's actually a good question. If all of your VM's are idle, you would want your host CPU to idle as well, although my guess is this doesn't happen in things like Xen, VMWare, etc.

Wish I had more upvotes for this. It's surprising how intolerant people become once their opinion becomes the socially acceptable one.

Just wanted to say thank you for hlld/bloomd! At my old company we were looking into uses for them just because the idea and footprint was so cool. We had a couple ideas for hlld and the overhead was so small that we could basically add it to our servers for free.

> We figured pretty much everybody knows JavaScript

Even with the implied "everybody" being "everybody that would be interested in joining our site", this is a poor assumption. Not everyone is a ninja-rockstar web developer. In fact, some of the best content on HN comes from people who most likely don't know JS. I get the idea for the site, but the description seems very naive.

(FWIW, I do know JS)

Waaaay too close to the Poe's Law line, I can't tell if this guy thinks this is for real or if he knows it's ridiculous and is just trying to cash in on demand.

What would be really cool is if this list of genres was open-sourced somewhere. I can see Netflix not wanting that, but it would really save time for however many hackers read this article and decide they want the same data.

They're trying to italicize the word via markdown (which accepts either _ or * ), but HN only supports * . So _really_ should be really

10.0.0.1 or 0x0a000001?

4.2.2.1 or 0x04020201?

Mostly readability and speed of typing, I would think.

A general thanks to aphyr for exploring all of these kinds of issues in distributed datastores at a level where someone without a lot of database knowledge can understand and reason through. If anyone hasn't read his Jepsen series and is interested in these kinds of things, it is well worth a read.

Of course, I wouldn't read it if you store very important data in any of the datastores he talks about, you might be scared to learn how your system actually operates =).

P.S. - The Spanner link is broken, you have some invisible character being added to the end, gets encoded to %E2%80%8E

I think so, following the opt-out link led me to sign up for a G+ account (I'm in the same boat where I have a Google account but no G+).
