London.pm

London.pm is a technical user group focused on the Perl programming language, based in London, United Kingdom. It convenes practitioners, authors, and technologists around topics in software development, web applications, systems administration, and open source practices, attracting attendees from corporations, startups, and academic institutions. The group has served as a nexus connecting speakers, conference organizers, and community projects across Europe and North America.

History

London.pm traces its origins to the late 1990s when interest in Perl 5 and the maturation of CPAN coincided with developer meetups in London boroughs such as Camden, Islington, and Southwark. Early meetings featured speakers associated with projects like mod_perl, DBI, and Catalyst and drew contributors from companies including Yahoo!, IBM, Sony, and Sun Microsystems. The group intersected with events such as YAPC::Europe, PerlConf, and community initiatives tied to Open Source foundations like the Apache Software Foundation and the Free Software Foundation. Over successive years London.pm hosted contributors who later worked on platforms including GitHub, MetaCPAN, CPAN Testers, and services developed by Google, Facebook, and Twitter. The membership reflected personnel from institutions such as University College London, Imperial College London, King's College London, City, University of London, and cultural venues like The Barbican Centre and Royal Festival Hall where public tech events were sometimes staged.

Activities and Events

Regular activities include monthly talks, hackathons, and social meetups often scheduled in venues near London Bridge, Paddington, or Old Street. The group organized special sessions aligned with conferences including OSCON, FOSDEM, EuroPython, and JSConf crossover events to highlight interoperability between Perl 5 ecosystems and technologies from Node.js, Python 3, Ruby on Rails, and Django. Past event topics covered integrations with PostgreSQL, MySQL, SQLite, MongoDB, Redis, and cloud platforms like Amazon Web Services, Microsoft Azure, and Google Cloud Platform. Presentations examined tooling such as Git, Docker, Kubernetes, and CI systems like Travis CI and Jenkins. The group collaborated with meetup partners including London Ruby User Group, PyData London, DevOpsDays, Women Who Code, and Tech Meetup. Keynote speakers have included authors of influential works published by O'Reilly Media, editors from ACM, and contributors recognized by awards like the Turing Award and the British Computer Society fellowships.

Community and Membership

Membership spans professional developers, systems engineers, academics, and hobbyists from organizations including Barclays, HSBC, Goldman Sachs, BBC, The Guardian, Bloomberg, and TransferWise. The social fabric of the group linked to wider networks such as Perl Foundation, UKLinuxUsers, London Software Craftsmanship Community, and student societies at University of Westminster and Queen Mary University of London. Outreach activities have been coordinated with diversity-focused groups like Ada Initiative allies and chapters of Women in Tech and Black Girls Code-aligned meetups to broaden participation. Communication channels included mailing lists, IRC on networks like Freenode, and platforms hosted at MetaCPAN-adjacent sites and repositories on GitLab and GitHub.

Projects and Contributions

Members contributed to many open source projects on CPAN, modules for DBI and Mojolicious, and frameworks like Dancer and Catalyst. Collective efforts produced tools integrating HTML5, CSS3, JavaScript, and templating systems influenced by Template Toolkit. Contributions extended to interoperability with SOAP, REST, and protocols used by OAuth and OpenID Connect. The group supported test automation efforts with Test::More, Test::Harness, and CPAN Testers, and aided localization efforts connected to Unicode handling and IETF standards. Members authored technical papers presented at venues like EuroSys, ICSE, and SREcon and contributed modules adopted by projects under the Mozilla Foundation and Creative Commons.

Governance and Organization

London.pm operated as a volunteer-run association with roles including conveners, treasurers, and event organizers drawn from the membership and coordinated with sponsors from firms such as Canonical, Red Hat, Atlassian, and Elastic NV. Organization relied on community bylaws and practices similar to groups affiliated with the Perl Foundation and other language user groups such as Python Software Foundation-aligned meetups and Ruby Central. Financial and logistical support came from corporate sponsorship, ticketing platforms, and partnerships with coworking spaces like WeWork and venues managed by TechHub. Collaboration platforms and project management used tools by Atlassian (including Jira and Confluence), Trello, and version control services from GitLab and GitHub.
