What’s so great about functional programming anyway?
To hear some people talk about functional programming, you’d think they’d joined some kind of cult. They prattle on about how it’s changed the way they think about code.

Is Perl 6 Being Renamed?
By now, many of you have seen the Perl 6 Github issue "Perl" in the name "Perl 6" is confusing and irritating . The issue suggested renaming Perl 6. While some may think that the name of the issue is trolling, or offensive, the actual issue was created by Elizabeth (Liz) Mattijsen, one of the core Perl 6 developers, a…

Unreal Rust
A few months ago I asked myself "What if I could write a game in Rust, but use Unreal as a renderer?". After a bit of thinking I came to the conclusion that exposing the Unreal renderer to Rust via C ffi was way more work than I was willing to do.

Perl's decline was cultural
There's been a flurry of discussion on Hacker News and other tech forums about what killed Perl. I wrote a lot of Perl in the mid 90s and subsequently worked on some of the most trafficked sites on the web in mod_perl in the early 2000s, so I have some thoughts. My take: it was mostly baked into the culture. Perl grew…
