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.

I've been wanting to do a serious project in Go. One thing holding me back has been a my working environment. As a huge PyCharm user, I was hoping the Go IDE plugin for IntelliJ IDEA would fit my needs. However, it never felt quite right. After a previous experiment a few years ago using Vim, I knew how powerful it could be if I put in the time to make it so. Luckily there are plugins for almost anything you need to do with Go or what you would expect form and IDE. While this is no where near comprehensive, it will get you writing code, building and testing with the power you would expect from Vim.
I'm assuming you're coming with a clean slate. For me this was OSX so I used MacVim. There is nothing in my config files that assumes this is the case.

$ openssl rsa -in server.orig.key -out server.key |
