Going Rogue

For many years I’ve enjoyed listening to programming podcasts - it’s the perfect way to make a commute a bit more fun and educational.¹ RubyRogues was always one of my favourite Ruby shows and I find it very amusing that recently I ended up being their guest. I certainly didn’t see this coming! Seems that a lot has changed since the days I followed it actively, but it was still fun to make an appearance there.

If you’d like to listen to our conversation about RuboCop, Emacs and the future of Ruby be sure to check out this episode.

Until next time!

If I Could Turn Back (Git) Time

If only there was an easy way to find the first commit in a Git repository… A bit of Googling unveils some pretty hard to remember incantations like:

$ git rev-list --max-parents=0 HEAD
91938b105b3e4ed86ba96602785123ffb1c0d1eb

That returns the SHA-1 hash of the first commit in the repo and you can use git show to actually see the commit details like this:

$ git show 91938b105b3e4ed86ba96602785123ffb1c0d1eb

Or you can simply combine the commands:

$ git show `git rev-list --max-parents=0 HEAD`

This gets the job done, but it’s kind of ugly and in practice you need to map it to some Git alias or a shell alias to be able to use it effectively. Here’s the shell alias approach:

alias git-first="git show `git rev-list --max-parents=0 HEAD`"

At this point it’s time for the twist it our story. Turns out there’s a much simpler way to get to the beginning of your history:

$ git log --reverse

Simple and sweet!

Migrating from Octopress to Jekyll

After dreading the migration of this site from Octopress 2 to Jekyll for years, I finally found the will to do it today. The process was actually very straight-forward and took me just a couple of hours (most of which I spent trying to find new a theme for the site and tweaking it afterwards).

Back in Black

After 3 years of “waiting” for Octopress 3¹, I’ve decided I waited long enough. Today I (spontaneously) migrated my blog to a vanilla Jekyll setup and I tweaked a bit its appearance. I’m reasonably pleased with the result and I finally don’t have any excuses not to write.²

I realized recently that it has been over 10 years since my first blog post.³ I’ve started my humble writing “career” with Wordpress, then switched to Octopress, and now here we are. One thing never really changed, though - the quality of my writing. It was always abysmally bad, as were many of the topics I wrote on. It’s really fun to look back on all of this - I was reading some of my old articles, in the process of migrating the blog to Jekyll, and I couldn’t believe some of the things I wrote. I hope this means I’m getting wiser with age…

In the mean time I’ve started another blog, called Meta Redux. I plan to do most of my (serious) writing there, but I might write an occasional short article or two here as well. My rough idea is to use Meta Redux as a platform for my more creative writing, and to use (think) for random stuff, small tips, etc.

Anyways, lately I’ve had this burning desire to share so many thoughts and that really got me excited about writing. Let’s see if I’ll do better this time around, or I’ll simply fail one more time…

CIDER 0.9

CIDER 0.9 is finally out and it’s our best release yet (believe it or not)! It took a lot more time than I originally anticipated, but at least we managed to ship in time for EuroClojure!

There are a ton of important changes and new features in 0.9 and now I’ll go quickly through some of them.
