Working off from LDA project on RadiusNetworks/lda#7

What I expect:

• The go get command sets gonum version in go.mod to gonum revision
• Running the tests succeed

What I observe:

• The @revision of go get is ignored
• The latest version is fetched setting the revision to the last commit on master
• go test fails

Summary

The following instructions will install Vim with the Ruby interpreter and Command-T. I keep my vim settings under revision control, thus I have chosen to use Git's submodules and Pathogen to manage Command-T. Depending on your preferences, you may want to setup Command-T differently. I recommend reading through the Command-T Readme

Install dependencies (what my system required), hg, and rake

sudo apt-get install ruby ruby-dev libncurses5-dev mercurial clone build-essential rake

I chose to compile vim with my system Ruby, 1.8.7. It is important that you use the same version to compile both Vim and Command-T. If your using RVM and you want to do the same, before proceeding you will want to:

rvm use system

Freezer cgroup FTW

In a terminal start a server.

$ python -m SimpleHTTPServer 8000

In another terminal set up the cgroups freezer.

Currently, there is an explosion of tools that aim to manage secrets for automated, cloud native infrastructure management. Daniel Somerfield did some work classifying the various approaches, but (as far as I know) no one has made a recent effort to summarize the various tools.

This is an attempt to give a quick overview of what can be found out there. The list is alphabetical. There will be tools that are missing, and some of the facts might be wrong--I welcome your corrections. For the purpose, I can be reached via @maxvt on Twitter, or just leave me a comment here.

There is a companion feature matrix of various tools. Comments are welcome in the same manner.
