Tech challenges, ready to pick up.

Solved looks like

A desktop YouTube user can post a GIF comment with the extension and it stays up after reloading the page.

Solved looks like

A GTFS timetable feed for at least three provincial routes, including Fogo Island and Bell Island, built from the PDFs, that passes the MobilityData GTFS validator with no errors and loads in a trip planner. A short note lists anything the PDFs leave unclear.

Solved looks like

An sci() function in CO2.js that takes operational emissions, embodied emissions and a functional unit and returns a score, with unit tests based on the SCI specification and a documented page-visit example.

Solved looks like

A JupyterLab plugin with a public announce() function and settings to turn announcements off and set a delay, old messages cleared automatically, and at least one real feature using it. Tested with NVDA and VoiceOver.

Solved looks like

Every configured swipe action is offered as a TalkBack action on each message in the list users actually get, confirmed on a real device by a TalkBack user.

Solved looks like

A firmware option that puts the GPS into low-power mode after a set time with no motion and wakes it on movement. On a bench test with an accelerometer-equipped node, current draw measured with a USB power meter drops while still and position updates resume within a minute of moving.

Solved looks like

A command-line tool that lists every skill installed across agents on a machine, flags duplicates and broken file references, checks each SKILL.md against the spec, and runs each skill's example prompts as a smoke test. Demonstrated on a folder of 20 community skills.

Solved looks like

A design note and prototype for an opt-in size limit that removes least-recently-used entries after an install, without breaking other uv processes running at the same time. Tested by filling a cache past the limit and checking it ends under the limit while recent packages still install offline.

Solved looks like

A Matrix receiver in Alertmanager configured with homeserver address, room id and an access token read from a file, posting firing and resolved alerts with the standard templates, with an integration test against a local Matrix server in Docker.

Solved looks like

A firmware setting for up to three privacy zones (centre and radius). Inside a zone, the position sent is rounded to the zone's precision; outside, the normal setting applies. Checked on a bench node with simulated GPS that the exact home position is never transmitted.

Solved looks like

A Yarn plugin or patch that, at install time, fails with a clear message when a package that had provenance in earlier versions resolves to a version without it. Tested against a local test registry with a downgrade case and a never-had-provenance case.

Solved looks like

A small web service and form: given a Transitous trip id, it works out which feed the trip came from, returns the right contact (or says none is known) and a prefilled report. Tested on 20 trips from different feeds.

Solved looks like

A test that reproduces the bug on current main, and a fix so a DAG-level failure callback fires exactly once when a run fails, including on timeout, checked with LocalExecutor and KubernetesExecutor.

Solved looks like

A free web tool where someone pastes a draft and gets back every case and statute citation in it, each marked as found on CanLII (with a link), not found, or found with a different name or year. Tested on 20 real Canadian decisions with planted fake citations, it catches every planted fake and wrongly flags fewer than 1 in 10 real citations.
