Well, today I finally did it. Just to test the cloud machinery I'm (ab)using here, I'm writing this post as a new commit on GitHub in a browser. When I get done and commit this, Travis CI will fire up, install my node-based blog code and build all the content. Assuming that goes well, my code on Travis will then publish any changes in the content to Amazon S3. And, voila, I will have blogged via the magic of cheap cloud infrastructure. Up until now, I've been doing this all from my laptop: Write a post in Vim, commit to git, build & deploy from my local machine. I'd push to GitHub to work in the open and have a handy backup. But from here on, the push to GitHub will actually make the magic happen! If you're curious about the plumbing, [the changes in my recent commits][recent-commits] can tell the exact story. But, what I did in a nutshell is this: * [Switched to using environment vars to configure AWS credentials for S3 publishing][env-config]. * Used [`travis secure`][travis-secure] to supply credentials in encrypted environment vars. * Started [maintaining a copy of file hashes on the site][hash-stash] so that [gulp-awspublish][] will only publish changes. * Composed a [.travis.yml][travis-yml] to build & deploy everything. And, if you're reading this post, then that means everything worked when I hit the "Commit new file" button! (And, if you're reading *this* sentence, then I was able to update this post, too!)
