Outreach Opportunity Type: contributor-onboarding Target: Hacktoberfest 2026 (Oct 1–31) Strategic Priority: Community-funnel tier 2 (ADOPTION-METRICS.md) Related: Q4-ADOPTION-PLAN.md (lever: #1537) Overview Hacktoberfest 2026 is a proven funnel for converting first-time contributors into sustained community participants. TunaOS's first external human contributions merged on 2026-08-14 (docs#234, docs#239), validating the fork→PR onboarding loop end-to-end. The Q4 adoption plan targets: 09-15: 15–20 usable "good first issue" (GFI) seeded across ≥6 repos 10-01: Hacktoberfest launch + curated GFI live 10-31: ≥10 merged PRs from new contributors (conversion target) Current Status Tracker: #1537 (Hacktoberfest tracker) Date: Seeding deadline 09-15 (T-39 days from 08-14 checkpoint) Evidence baseline: COMMUNITY.md documents contribution ladder and fork→PR loop; docs-repo proves end-to-end conversion Deliverables Per tracker #1537, seeding requires: Audit all TunaOS org repos (
Goal ADOPTION-METRICS.md defines a monthly-snapshot KPI system for Q4 2026 "Mature" goal, with the first snapshot due November 1, 2026 (covering October activity). This snapshot feeds roadmap decisions and demonstrates Q4 adoption progress. Current blockers: GitHub Releases download counts: waiting on non-GNOME flavor asset publishing (pending #1254 parity PR) R2/Cloudflare access-log dashboard: not yet enabled (owner: ci-maintainer) Docs site analytics: not yet instrumented (owner: guide) Snapshot content and ownership assignment: not yet scheduled What Needs to Happen (by Nov 1) Data collection (prerequisite) GitHub Releases API (free, can start now): Verify that all five flavor flavors (Yellowfin, Albacore, Skipjack, Bonito, Redfin) publish assets Baseline the download count per flavor×desktop (top 10, if volume allows) Confirm asset publishing is stable for the Oct 1–31 window R2 access logs + Cloudflare dashboard (medium lift): Enable access logging on R2 (tunaos.org/d
Problem COMMUNITY.md publicly claims "Hacktoberfest 2026: We are participating!" and links to good-first-issue search. As of Oct 6, the pool contains only 6 contributable tasks across 2 repositories (#1798–#1800 in tunaOS, #231 and #275 in docs). Launch requirements (per HACKTOBERFEST-2026.md): 10–15 good-first-issue tasks Across 3+ repositories None should dominate (no single repo >50%) Current reality: 6 tasks (40% below minimum) 2 repos (third needed) tunaOS dominates at 50% This gap makes the public claim in COMMUNITY.md false advertising. New contributors following the banner find an empty pool and a poor onboarding experience — exactly what the Hacktoberfest plan exists to prevent. Solution Seed 4 additional starter-task issues in two underrepresented repositories before October 1: Option A: Corral (Kubernetes-native VMs — approachable for container/K8s-familiar contributors) Issue 1: "Add GitHub Actions workflow for unit tests" (bounded, new-contributor-friendly) Is
Design Community Engagement Opportunity TunaOS has 12 distinct variants (Yellowfin, Albacore, Bonito, etc.) but ships with generic backgrounds. This is a low-barrier entry point for designers and artists. Opportunity Creative contributions (wallpapers, themes, variant logos) have zero technical barrier — designers new to open source can participate without code. This broadens contributor base beyond developers. Proposal Create design directory structure — docs/design/wallpapers/{variant}/ Design brief — simple template: variant name, mascot, theme direction, color palette Submission guidelines — format, licensing (CC0), attribution Showcase — link from README and tunaos.org Scope: 12 Variants 🐠 Yellowfin (AlmaLinux Kitten) 🐟 Albacore (AlmaLinux 10) 🍣 Skipjack (CentOS Stream 10) 🎣 Bonito (Fedora 44) 🐦 Hummingbird (Fedora) 🎏 Wahoo (Fedora ELN) 🔒 Redfin (RHEL 10) 🪸 Grouper (Ubuntu 26.04) 🤖 Gurnard (Ubuntu 24.04) 🚀 Marlin (Arch Linux) 🐡 Flounde
We'd love to ship wallpapers made by people. The current ones are placeholders: scenes drawn by a script from Noto Emoji. Until artwork arrives, some slots may temporarily hold AI-generated images. We will replace every one of them with human work as soon as it comes in. If you paint, draw, photograph or find art that fits, please share it. What each variant looks like Each TunaOS variant has its own identity. Its name and emoji are the brand, and an accent color nods to the distro it's built on. Every scene is somewhere by the sea. variant mark built on accent scene idea Albacore 🐟 AlmaLinux cobalt blue a harbor town; a tuna breaking the surface Yellowfin 🐠 AlmaLinux Kitten golden yellow a sunlit tropical lagoon Skipjack 🍣 CentOS Stream plum and violet a tiny seaside sushi counter at twilight Wahoo 🎏 Fedora ELN deep indigo a Japanese seaside village; koinobori in the breeze Bonito 🎣 Fedora pale morning blue an old pier on a calm morning; a rod bending B
