Mood Lighting
The lighting in my bedroom uses Philips Hue bulbs — specifically, the coloured ones. Last night, I decided it would be nice to set the three lights in my bedroom to cycle slowly through a set of warm colours using…

Finding Squares in Matrices
I don’t usually take part in the Perl Weekly Challenge but one of this week’s challenges caught my eye. I thought it could be a fun thing to attempt and decided to use Zydeco to help solve it. The problem…
Applying Operators to Coderefs

There is a line between them, even if it’s interrupted by a circle. And what about these two circles? Are they connected? Again, there’s a diagonal line […]
