True, good point!

I think you misread my comment; I said its unlikely to have a consistent system that can service reads but not writes during some manner of disruption.

Yep, the Yammer article is just opinion. It may or may not match your experiences/beliefs :) Check the Spanner paper for slightly more data (but its still pretty informal) from Google. They don't talk about other systems, but they

Yes; in vanilla Paxos you need a majority of nodes to be up/reachable to service either a read or a write. There isn't really a distinction between read/write in terms of availability (for better or worse.) I think its pret

by jacobparker 9y ago
What they're trying to explain is that so-called AP systems do not have 100% availability either. The CAP theorem applies to very specific scenarios that are not necessarily common - it is a much more narrow theorem then "CP vs AP

Wow, I don't remember that part at all (I was really young when I used it.) Thanks.

Was it because of musl libc? These images use glibc.

They mention that in the video. It's an easy way currently to get built packages. Bazel has plans on their roadmap ( https://www.bazel.build/roadmap.html ) to open-source rules for common packages ("Repository of BU

The images still have some "weird" stuff in them like man pages because they use deb packages from debian for common packages. That's not core to the idea, though (and note that apt is not included inside the container.)

An alternative way to create small container images is to not base them off a distro at all: https://news.ycombinator.com/item?id=15415992

Reinventing escaping over and over again (which bash scripts in particular seem to encourage) is a suckers game. It's difficult to get right and if you're constantly redoing it you're eventually going to make a mistake. I&#x

That's sorta the point... the init isn't the branch condition. It gives terser syntax to a common patter where you want to scope something into the body of an if statement. { std::unique_ptr<T> x = foo(); if(x-&g

This appears to be a new edition/refactoring/redesign of the previous version of Software Foundations. I haven't had much time to look through it but it looks like there is new material (volume 3?) (EDIT: found a hosted copy

CA is a not really a valid/possible thing in the context of CAP. The original phrasing of the theorem was poor and the "choose 2" myth persists. You can choose to (or accidentally) give up C or A but you don't get to cho

This isn't quite right. Even with SR and the speed of light its possible to build consistent systems and achieve consensus. Not-eventually-consistent doesn't mean instantaneous. The SoL just sets a lower bound on the speed of cons

I did, but I didn't mean it in a negative way! The Racket one is definitely more towards the "practical" side than the C++ one (C++ is more constrained when it comes to how it can embed DSLs) but for me it falls into a simila

Depending on your database (I'm assuming some manner of SQL) you could create a view that is denormalized and supports SELECT/INSERT/UPDATE/DELETE for human query UX.
