COSCon 2025: the Linyaps invitation and the deepin community booth

Original publication: 2025-12-05. English edition and practical reading notes: Linglong editorial, 18 October 2026. Chinese original.

The Linyaps invitation was published on 5 December 2025 for COSCon on 6–7 December 2025 at the Park Plaza Beijing Science Park hotel in Haidian, Beijing. This event has ended; the invitation and map are historical records.

The invitation’s theme

The article traced COSCon to an initiative by KAIYUANSHE in 2015, with the name adopted in 2016. For its tenth-year milestone, the 2025 theme was “Open Source, Open Intelligence”, focusing on AI and open-source collaboration. It described a main forum and 24 concurrent activities or thematic forums.

Linyaps was to appear with deepin in the open-source bazaar. The invitation described community check-in activities, open-source quizzes and opportunities to receive community merchandise. Its registration invitation and QR material belonged to that event, not an offer of current tickets or gifts.

A companion copy adds the venue context

The deepin invitation for the same event preserves a venue map and a forum program. The map’s exhibitor list identifies deepin at number 19. The program is dated 6 December and lists the UOS AI talk from 16:00 to 16:20. These are announced coordinates and times, not proof of attendance or a current visit plan.

Prepare one useful booth question

Use a project booth to resolve a concrete uncertainty. For a packaging project, bring the application ID, target distribution and the first failing step. Ask which maintained example or issue tracker matches that case, and record the answer’s date.
