Are you talking about Go, the language this is written in? Go's concurrency features are formally specified, are not ad-hoc (they are a major feature of the language, and the product of multiple language design iterations) and are cert

Apparently a prototype was written in Java. Borg was written in c++. AFAIK Kubernetes was always a Go project, but maybe I'm wrong. Why do you think Go was chosen? Your comment about my experience with Java was needlessly provocative s

Kubernetes is a complex project with a large codebase. Writing it in bash would be a nightmare to maintain. Go makes sense as an implementation language for a system like this for many reasons: - it doesn't require a VM (goodbye Java)

Yes it's supposed to start with another member bringing it up in private, then maybe reaching out with several members, then bringing it before the elders, etc. Missing church every Sunday would be particularly visible, especially in a

Yes this is true. And it's a good thing to remember to ask about when applying for jobs (and seems like an entirely reasonable thing to want to know before you sign up) It was helpful when I had a more structured on-call rotation and o

Many churches practice church discipline, for example with the PCA: http://www.pcahistory.org/pca/3-443.html It mostly applies to leadership, but also members. Possible "censures" include: - Admonition (ie ca

Being a backend engineer with occasional on-call responsibilities, this is an unfortunate reality I've had to deal with. My religious tradition (reformed evangelical christian) takes the sabbath pretty seriously, as stated in the Westm

Seems like the best way to tell is to not actually look at the face so much as the details around it. There are often obvious glitches in the background.

Go is not fully preemptive, but in practice it usually is (it preempts at function calls): https://github.com/golang/go/issues/10958 .

This algorithm is great. I was working on a new metric alert evaluation system and built an expression parser for things like: system.disk.free{*} / 1024 by {host} The naive approach to parsing will result in the wrong order o

A few reasons: 1. At least for me, I didn't know the game going in so I wasn't prepared for it. A lot of folks I interview don't either (though its becoming less common... almost everyone is somewhat prepared for it now), and

Not really a networking issue. Channels are (relatively) inefficient for small payloads. With a decent payload size they're almost never the bottleneck in a real-world program. You really have to benchmark it. It sounds like in this ca

That's what, 8GB of ram? A lot for a laptop... but not too much for a server.

In Go you can write unsafe code in libraries. You can even write raw assembly if you want. We had an encoding library written in a very c-ish style for maximum performance, and sure enough, it had an off-by-one error on the last byte that c

The whimsical nature of interfaces is definitely different coming from other languages. An `io.Flusher` might be nice, but it's not really necessary. You can just write: type Interface interface { io.Writer Flush(

This is how the cluster-autoscaler works in kubernetes. It sets the desired capacity based on the number of pods needing to be scheduled. Coupled with a horizontal pod autoscaler (which sets the replica count based on a metric) you get the

If human beings have a libertarian sort of free-will (the ability to do otherwise), then their actions can't be caused by God. So if we imagine a free-will choice, say whether or not to mow the lawn today, it's possible for me to

Do most non-theists believe in a meta-ethical realism? The incompatibility of properties is precisely the issue Plantinga takes up. He offers a defense based on free-will. That there are possible worlds in which free people choose only to d
