FIT files record the activities of people using devices such as sports watches and bike head units. Platforms such as Strava and Zwift understand this now quasi-standard format. So does Perl! Here I discuss how to parse FIT files and calculate some basic statistics from the extracted data. Gotta love that data I love data. Geographical data, time series data, simulation data, whatever. Whenever I get my hands on a new dataset, I like to have a look at it and visualise it. This way I can get a...| Articles on Perl.com - programming news, code and culture

In the previous post, we created a network close enough to reality so that finding routes between stations was possible and sufficiently interesting. In this final post in the series, we’re going to see how to handle indirect connections between stations. Alternative connections Not all stations in the Hannover tram network are directly connected. A good example is the line Linie 10, which starts at the bus station next to the main train station and has the station name Hauptbahnhof/ZOB.1 A...| Articles on Perl.com - programming news, code and culture
SlapbirdAPM is a free-software observability platform tailor made for Perl web-applications. [ It is also a Perl web-application :^) ] It has first class support for Plack, Mojo, Dancer2, and CGI. Slapbird provides developers with comprehensive observability tools to monitor and optimize their applications’ performance. In this article I will explain how to setup a Plack application with Slapbird.

The Perl Toolchain Summit 2025 From May 1–4, 2025, the invite-only Perl Toolchain Summit (PTS) brought together in Leipzig, Germany, 33 of the ecosystem’s most active maintainers — and welcomed 6 first-timers — for four days of uninterrupted deep-dive collaboration in pair-programming sessions, consensus discussions, and critical infrastructure work. Attendees tackled security tooling and infrastructure, modernization and redesign proposals, several CI and test harness improvements, P...| Articles on Perl.com - programming news, code and culture
The previous post focused on adding more lines to the network and adding colour to those lines. This time, we’ll add another line, but now the map will better match reality. This will allow us to start finding routes between stations on the network. Building complexity It’s time to get a bit trickier. In the real tram network in Hannover, the main hub is actually the station Kröpcke and not Hauptbahnhof as we’ve been using so far. Therefore, if we want to add further lines, we’ll hav...| Articles on Perl.com - programming news, code and culture

The first post in this series introduced us to Map::Tube. There, we built the fundamental structure of the Map::Tube::Hannover module and created the basic map file for the Hannover tram network. This time, we’ll look at a map file’s structure and extend the network. At the end, we’ll visualise a graph of the railway network we’ve created so far. Structural understanding Now that we’ve created a basic map, our goal is to understand the structure of Map::Tube maps a bit more. This wa...| Articles on Perl.com - programming news, code and culture
