Impacts
PCC · PERL COMMUNITY · SCIENCE PERL
Useful work. Shared knowledge. Lasting impact.
Conferences connect the people creating, studying, maintaining, and teaching Perl 5. Here is a documented snapshot of that work through Summer 2026, checked on October 31, 2026.
*57 scheduled PCC technical talks and eight delivered Las Vegas 2024 Science Perl presentations. Program counts are not claims that every scheduled slot was delivered or recorded.
Four conferences, plus the founding Science Perl track
| Program | Technical slots |
|---|---|
| Winter 2024 PCC | 10 |
| Summer 2025 PCC | 10 |
| Winter 2025 PCC | 15 |
| Summer 2026 PCC | 22 |
| Las Vegas 2024 Science Perl track | 8 |
PCC counts include lightning talks and technical keynotes. They exclude openings, closings, interludes, reports, panels, memorials, addresses, receptions, and entertainment. The Las Vegas track is counted separately from the four PCC conferences.
Recordings that keep the work accessible
The three inventoried PCC playlists contain 41 recordings totaling 21 hours, 27 minutes, and 31 seconds. This includes reports and opening/closing segments; it is recording time, not a technical-talk-hours total. It includes recordings supplied in an unlisted collection, so it is not a count of publicly released videos.
Six additional Las Vegas Science Perl recordings are linked in our archive; their running time is not included above. The curated Past Talks page currently features 27 recordings. Playlist catalogues and the curated selection measure different things.
People contributing research and practical experience
At least 31 named people appear across the published technical programs, the Science Perl track/SPJ author list, and the documented externship presentation. A person appearing at several events is counted once. Unnamed panelists, co-presenters, volunteers, reviewers, and collaborators are not added to the total.

Projects and tools shared with the community
The schedules identify at least 22 project/tool groupings featured in presentations. These are tools discussed by speakers, not a claim that PCC created, owns, or funds them. Closely related names are grouped to avoid inflating the count.

How to read these numbers
This is a documented minimum, not a complete census of everyone’s contribution. The sources are the four linked conference schedules, the three PCC recording collections, the Science Perl Journal, and its published Science Perl track list. Talk counts, recording counts, hours, people, papers, and projects have separate definitions; they should not be added together into one total.
