When I first got it I thought that I’d be doing well to get 4 years out of it. Well 4 years later and the SD card capacity to price ratio had improved enough that I could start using my FLAC files directly rather than the having to convert them to MP3. Or at least I could if my MP3 Player supported FLAC files, which of course it didn’t. https://www.heckrothindustries.co.uk/projects/listgroupby/ Mon, 22 Feb 2021 00:00:00 +0000 https://www.heckrothindustries.co.uk/projects/listgroupby/ List::GroupBy is a Perl module that takes a list of hash references and groups them by one or more of their keys. https://www.heckrothindustries.co.uk/ramblings/advent-of-code-2020-day-1/ Fri, 04 Dec 2020 00:00:00 +0000 https://www.heckrothindustries.co.uk/ramblings/advent-of-code-2020-day-1/ So, it’s that time of year again when I spend a bit of time tackling some of the Advent Of Code challenges. As a bit of an exercise I’ve decided to write down an explanation of how I tackled Day 1. Part 1 Each Day’s challenge consists of two parts and the simplified explanation for the first part for Day 1’s challenge is: Given a list of numbers find two that numbers that add up to 2020. https://www.heckrothindustries.co.uk/projects/keywordtailrecurse/ Fri, 07 Feb 2020 00:00:00 +0000 https://www.heckrothindustries.co.uk/projects/keywordtailrecurse/ Keyword::TailRecurse is as a Perl module that enables true tail recursion that doesn’t increase the stack. https://www.heckrothindustries.co.uk/projects/mojoliciouspluginservertype/ Fri, 17 Jan 2020 00:00:00 +0000 https://www.heckrothindustries.co.uk/projects/mojoliciouspluginservertype/ Mojolicious::Plugin::ServerType is a simple Mojolicious plugin that provides a helper that identifies the type server the Mojolicious app is running under (e.g. Mojo::Server::Prefork). https://www.heckrothindustries.co.uk/ramblings/dbd-mock/ Wed, 09 Oct 2019 00:00:00 +0000 https://www.heckrothindustries.co.uk/ramblings/dbd-mock/ A few months ago I started using the DBD::Mock Perl module as part of some unit tests for a project I was working on. It was pretty simple to pick up and use, but I found that there was a feature missing that would make it easier for me to use. As it’s open source I was able to dig into the module’s code and figure out how to add the new functionality. https://www.heckrothindustries.co.uk/projects/dbdmock/ Tue, 17 Sep 2019 00:00:00 +0000 https://www.heckrothindustries.co.uk/projects/dbdmock/ I currently maintain the DBD::Mock Perl module. Note: that the majority of this module was developed by others, who put a lot of work into making a great module that’s easy enough for me to maintain. https://www.heckrothindustries.co.uk/projects/partialapplication/ Tue, 17 Sep 2019 00:00:00 +0000 https://www.heckrothindustries.co.uk/projects/partialapplication/ PartialAppliation is a small Perl module that handles partially applying parameters to functions.
