Little Moments

Little Moments is an open-source web app I’m working on to replace the current family photo sharing app (TinyBeans) I used (which I strongly dislike).

• Worked on moving toward s3 support in small steps
• Improved the design doc
  • I realized I made Milestone 1 too big, so I broke it into smaller pieces
  • I added an explanation that the milestones are in order of ROI
  • I also left the CDN out of the original design
• Reorganized the tinybeans package and file I/O logic to a new importers/ subtree
• Renamed fileBaseURL to baseURL

go-app-starter

• Backported a bunch of improvements from Little Moments back into my Go app template
  • Add ETag caching and Cache-Control headers for static assets
  • Enforce external test packages in all Go test files
  • Fix check-frontend to pre-fetch npm deps with buildNpmPackage
  • Ignore Go build artifacts and pasted screenshots
  • Log full server URL with hostname on startup
  • Make e2e-tests derivation deterministic
  • Simplify test_sqlite by removing unused NewWithTime and init logic
  • Update AGENTS.md with comprehensive project guidelines
  • Use semantic HTML main element in base layout

Grosiree

Grosiree is a shared grocery list web app I’m making with my wife to show her how vibecoding works.

• Fixed a bug related to grocery item names with spaces

PicoShare

PicoShare is a minimalist web-based file sharing tool I’m working on. I’m often frustrated that I can’t just send someone a link directly to a file because every file-sharing service tries to re-encode images/video or wrap their own viewer around other files, so I’m making a simple self-hostable tool that lets you upload files and share them with other people.

• Reviewed a third-party contribution to add PS_SHARED_SECRET_FILE support
• Switched to Go 1.18+ VCS stamping instead of ldflags for build info
  • And cleaned up unused PS_VERSION that should have been part of the switch
• Continued working on the switch from mattn/sqlite to ncruces/sqlite

Vulnerability research

• Submitted two bug bounty reports to cryptocurrency projects
  • One was triaged but they said it will be several weeks before they have enough bandwidth to fully validate it
  • The other I just submitted this afternoon, so I haven’t heard back yet

Misc

• Submitted a PR to add an RSS feed to a new blog I like
• Did my taxes
