Open Source Contributions

Submitted the validated reliable-network-read browser example upstream so applications can distinguish a network response from locally cached GUN state.

• Reused and validated the existing fork work instead of creating a duplicate implementation.
• Submitted upstream as GUN pull request #1433 on September 18, 2026.
• The example was accepted upstream.

Documented a recovery gotcha found on enclosed LicheePi 4A boards: RESET and BOOT are separate keys, and some enclosures expose RESET while covering BOOT.

• Explains that RESET alone does not enter USB burning mode.
• Notes that the enclosure may need to be partially opened or removed to reach BOOT.
• Submitted as a focused documentation fix after reproducing the recovery workflow on physical hardware.

Added an opt-in skipParse path to SEA.decrypt so JSON-looking plaintext can be recovered exactly as encrypted without changing the default parsing behavior.

• Updated the canonical SEA bundle, extracted decrypt module, and TypeScript declarations.
• Added regression coverage; the upstream SEA test suite passes.

Added the Swarms AI startup program to the open startup-credits catalog, including its published Launch Tier benefit and eligibility requirements.

• Documents the $2,500 Launch Tier credit available for 12 months.
• Validated with the project's catalog verifier and git diff --check.
• Submitted with DCO sign-off.

Documented the upstream PowerVR BXM-4-64 graphics path for the LicheePi 4A, including the exact firmware and Linux/Mesa driver references needed to distinguish the mainline stack from older system-image graphics paths.

• Links directly to upstream Linux firmware and Linux/Mesa PowerVR documentation.
• Documents the Vulkan → Zink → OpenGL/WebGL browser path and practical vulkaninfo, glxinfo, and eglinfo acceleration checks.
• Validated with git diff --check and submitted with DCO sign-off.
• Accepted and merged into Sipeed’s official documentation on September 20, 2026.

Corrected the machine-readable ISA definitions so ld and sd are defined by I on RV64 and by Zilsd on RV32.

• Updated both doubleword load and store definitions.
• Passed Unified Database schema validation across the architecture files.
• Merged into the official RISC-V Unified Database on August 20, 2026.

I extended GUN's basic browser streaming example so peers could share microphone audio alongside video, making the example a more complete demonstration of real-time media over GUN.

• Added audio capture and playback to examples/basic/stream.html.
• Contributed 53 lines to the official example.
• Merged into the official GUN repository on July 25, 2025.

I turned an intermittent synchronization problem from real-world use into a repeatable PANIC regression test. The test creates a relay, writes a dynamic index from one browser, starts a second browser later, and verifies that the initial .map().on() subscription receives every indexed record without a reload.

• Added a 177-line automated browser test and configurable load controls.
• Documented the load-sensitive results across the repository build and published release.
• Merged into the official GUN repository on August 1, 2026.

Submitted regression tests and a compatibility fix for Python capture headers when build-time and test-time micro versions differ, addressing Debian bug #1146575. Thomas's PR #1048 was closed without merging on October 16, 2026, in favor of maintainer-authored PR #1055. The maintainer fix was reviewed and merged on October 27, 2026 (merge commit 3561af3d5bab87b1e5dcf47b2f9135745a41bd15). Thomas's submitted PR was not merged; this is an upstream resolution, not a Thomas-authored accepted patch.

Turned the Digital Organism from a personal-memory architecture into a running, user-owned experiment loop that can compare retrieval strategies, learn from explicit feedback, and remain independent of any one model provider.

• Runs three retrieval strategies against the same evidence and measures them with mean reciprocal rank and hit@1 before any strategy can be promoted.
• Captures safe finalized work on DigitalOcean and replicates the append-only Organism history to OVH about every five minutes, while excluding raw model output and synthetic health probes.
• Adds owner-signed “This was right” feedback bound to the exact query and memory ID; recall signatures cannot be replayed as approvals, and forgotten memories cannot be approved.
• Deployed the private Organism and signed feedback path through gated GitHub Actions with production verification.

Created a dedicated workbench for reasoning about tinygrad's associative-scan bounty without contributing AI-authored tinygrad code. The page tracks acceptance criteria, correctness cases, benchmark goals, implementation notes, and a definition-of-done checklist for a personally authored patch.

• Respects tinygrad's explicit no-AI contribution rule.
• Tracks edge cases including odd lengths, reverse scans, multiple axes, and non-commutative operations.
• Includes a browser-local notes and checklist workflow for human implementation.

Shared offline reproductions of two machine-control reliability problems: a fragmented ok acknowledgement can be discarded after a complete informational line, causing a false timeout, and startup status/configuration polling can wait indefinitely if the controller stops responding.

• Posted findings on upstream stepper PR #55 on October 24, 2026.
• Suggested preserving incomplete CRLF frame suffixes, bounded startup polling deadlines, and fake-serial regression coverage.
• Expanded the existing upstream review on October 25; ten local synthetic checks pass.
• On October 28, executed the pinned upstream GrblStage._send_msg offline with stubbed imports and fake serial: the unfragmented ACK passed, while a fragmented ACK reproduced the timeout in the actual driver. Audited Hetzner test result. On October 28, an in-memory one-line suffix-preserving parser candidate passed five deterministic fake-serial cases against the pinned actual driver; two fragmented cases still time out on the unchanged upstream code. Audited candidate test. No physical controller or stage movement was tested.
• This is a published upstream review with a tested offline candidate, not an accepted or merged patch or hardware-tested fix.

Reviewed the LicheePi 4A graphics enablement patch and reproduced a session-environment problem in Bash and Dash. Flagged hard-coded WAYLAND_DISPLAY and XDG_RUNTIME_DIR values, plus an unsupported MESA_VK_DEVICE_SELECT device-name selector.

• Submitted findings to upstream PR #707 on October 9, 2026.
• The maintainer confirmed the values were leftover testing settings and removed them in commit 80ae29b, confirming the updated configuration still works on hardware.
• This was an accepted code review, not a Thomas-authored or merged pull request.

I joined Debian's public RISC-V discussion around installing mainline Debian on the StarFive VisionFive 2, comparing the effort with my Sipeed LicheePi 4A and sharing Debian's board-installation resources.

From May through August 2024, I participated in Libre-SOC's development list while getting its HDL workflow running, discussing supported Debian environments, and exploring how an open business could help sustain open hardware development.
