I recently got an email of a friend of a friend looking for Clojure opportunities. I asked around on Twitter to find out who's currently hiring, and got a lot of responses. If you were thinking of making the jump to doing Clojure professionally there's no better time than now. Here's the original tweet and replies . Here are some of the companies that responded or got mentioned: Zalando (…
Macros are one of those language features that divide programmer communities. Some swear by their stupendous power, others reject them with a ferocity as if they are the breed of Satan. When asked Matz has always made his position clear: there is no place in Ruby for macros. I think he's right, the Ruby language has very little to gain by adding them.

Why Vim users will switch to Emacs in the coming years. I've recently stated that within the next five years half of Vim users will switch to Emacs. And while the exact time span and percentage are debatable, I stand by that statement. I think a number of factors are coming together that will make switching very appealing.

I don't remember exactly the first time I came across Ruby. It…
I have written and spoken a few times about the perils of string arithmetic on formal data. Those talks were focused on theory and fundamentals, in this post you'll get very practical tips. When programming for the web there are two types of formal data you'll come across All The Time , HTML and URIs. These formats have well specified structure and semantics, so that machines can unambiguously…
