Each entry can be checked at the linked page or in its commit and revision history. How to read it: the date is the date of the linked contribution, an e-mail, a post, a commit or a register entry, not the day it was added here. Profiles carry the day the account was created or, where the network does not show it, the start of the position they list. The sections follow the stages of his work, from the company registered in 2026 back to the first IPCop add-ons in 2003. Links to his own profiles and to the company hub carry `rel="me"`; every other link points to a page on another host.

## 2012–2017 · Dresden: C3D2, StuRa HTW, Plominski IT Consulting

Before Stockheim, Daniel Plominski’s traces lead to Dresden: the Chaos Computer Club Dresden (C3D2), where he committed the hackerspace’s RADIUS and network configuration; the student council of HTW Dresden, which credits him with its server setup; his firm Plominski IT Consulting with its blog blog.plitc.eu, 172 posts in the Internet Archive; and his FreeBSD and container tooling on GitHub.

Profiles in this section are dated by the day the account was created; SoundCloud, which shows none, by its only activity; the C3D2 and StuRa entries by the edit, the commit or the meeting. His mails to the OpenBSD and FreeBSD lists on Sun Fire hardware and IPsec sit here by date. Blog posts are dated by their publication date; pages that survive only in the Internet Archive link the capture, and the posts that other sites cited sit next to those citations.
