A teammate of mine recently expressed a desire for a shortcut for something we type often. I started looking into our shortcut options and came to a common determination: We can do this, but the number of 2 key shortcuts available to us is finite, so we better use them wisely.

Recently, I was working with a client that asked about using Percona Xtrabackup to take a snapshot of a particular MySQL schema and then reload it with a different schema name on the same server. It caught me off guard because I’d never really thought about it

One nice feature of nose is the multiprocess plugin. It allows you to run your tests suites concurrently rather than sequentially, spread across a number of worker processes. Running tests in parallel like this can potentially give you a large speedup in your test run times.

Since I was stuck in a hotel for a day, I thought I’d poke around devtools and see if I can try applying some anti-jank techniques. As usual, I bumped in to some problems, so I felt they were post worthy (if only for my memory).

Relational databases are still an important application component even in today’s modern application architectures. Amazon launched their RDS service which basically allows anyone to spin up a MySQL, Oracle, or MS-SQL instance whenever the urge strikes.

The other day I had the opportunity to speak with a good friend of mine who also happens to be a DBA at a global Financial Services company.

It’s not an exciting or glamorous subject but it’s an absolutely critical concept for properly managing your applications and infrastructure. CMDB, CMS, SIS, EIEIO (joking) or anything else you want to call it these days is a concept that has been poorly implemented from the very beginning.

Require.js also provides an optimizer script which compiles and compresses these modules into one (or a few) files for efficient delivery to the end-user. Sadly, when running the optimizer as part of a Maven build this process can take several minutes to complete. In this article I’ll explain how to speed things up a bit.

DevOps is scary stuff for us pure Ops folks that thought they left coding behind a long, long time ago. So here’s my plan: I’m going to do a bunch of research, play with relevant tools (what fun is IT without tools?), and document everything I discover here in a series of blog posts.

I thought it would be fun to compare Ruby with a few other languages by looking at how different open source developers implemented the same method or function in each language. How do the languages differ? Do they make you equally happy?
