I don't mean to speak for bcantrill, but yes, this is exactly how we (at Joyent) build programs. We wrote in detail about why we do it this way: https://www.joyent.com/developers/node/design/errors It&#

Part of the scientific method is that you generate hypotheses based on the data you have, not that you generate random hypotheses. It's a directed way of thinking. > The real hypothesis is that a small, localized portion of the cod

Sorry for the self-reply, but to clarify: the _implementation_ is Node.js. Users can run their actual workloads using any program they want.

I disagree that the JVM is the only platform on which you could (or would) build such a system. I know because we built a similar system at Joyent called Manta, which provides a distributed, Unix-based, map-reduce environment. It's b

That's interesting. We do something pretty similar in the Manatee component that I mentioned elsewhere in this thread, except that the designated synchronous standby can takeover if the primary goes away. But it can only do so when a

Thanks for writing this up! At Joyent, we built a similar system for automated postgresql failover called Manatee. I'm sure today we would have used a Raft-based system, but that was not available when we did this work, so we used Zoo

With postgresql synchronous replication, in order to lose writes that have been acknowledged to the postgresql client, you'd have to lose filesystem data on both the primary and the synchronous standby. (I believe the way postgresql u

When a client tries to send packets too big for the network (as when the client is configured with jumbo frames but the network isn't), this can be really painful to debug. The worst is that many things will work because small packets

There are some useful ideas here, and public shaming per se probably isn't the answer. But publicly talking about bad code, and the properties of code that makes it bad, is an important way to socialize what makes good code, plus the

It absolutely is, and has been for a long time. I find it very hard to keep track of the various standards, but things got a lot simpler with v3 of the Single Unix Specification, which is the same as POSIX 2001[0]. The problem is that SUS

Yes, that's definitely the direction that we're headed. Manta allows users to spin up large numbers of transient containers around their data (i.e., without moving data around) in order to do map-reduce operations, and without hav

It can, though it's not likely. The kernel only uses free ports even in the ephemeral range, so if an application binds to something in the ephemeral range first, then the kernel just won't pick it for new connections. You'

The ephemeral port range is per host because TCP connections are identified by the four-tuple: local IP, local port, remote IP, remote port. You can have active connections from localhost:12345 to both some_server:80 and some_other_server:

That's right. There's already so much that engineers have to keep in mind when programming. The less new stuff (particularly arbitrary stuff) people have to keep in mind when building software, IME, the more likely the software
