I recently happened upon a very interesting implementation of popen() (different API, same idea) called popen-noshell using clone(2), and so I opened an issue requesting use of vfork(2) or posix_spawn() for portability. It turns out that on Linux there's an important advantage to using clone(2). I think I should capture the things I wrote there in a better place. A gist, a blog, whatever.

This is not a paper. I assume reader familiarity with fork() in particular and Unix in general, though, of course, I link to relevant wiki pages, so if the unfamiliar reader is willing to go down the rabbit hole, they should be able to come ou

github.com/twotwotwo/sorts is a Go package with parallel radix- and quicksorts. It can run up to 5x faster than stdlib sort on the right kind of large sort task, so it could be useful for analysis and indexing/database-y work in which you have to sort millions of items. (To be clear, I don't recommend most folks drop stdlib sort, which is great, and which sorts depends on.)

While the process of writing it's fresh on my mind, here are some technical details, some things that didn't make the cut, and some thoughts about the process:

Concretely, what this looks like inside:

• Both number and string versions are in-place MSD radix sorts that look at a byte at a time and, once the range being sorted gets down to 128 items, call (essentially) the stdlib's quicksort.

• The [parallelization code

"Vendoring" is a vile anti-pattern

What is "vendoring"?

From a comment on StackOverflow:

Vendoring is the moving of all 3rd party items such as plugins, gems and even rails into the /vendor directory. This is one method for ensuring that all files are deployed to the production server the same as the dev environment.

The activity described above, on its own, is fine. It merely describes the deployment location for various resources in an application.
