Aspect at BazelCon

Everything from the booth in one place: product briefs, white papers, and the talks. Take what’s useful; the rest will still be here when you get home.

Our talks

Where to find us on the programme

Seven conference sessions and three Training Day workshops across all three days, plus two community events around the show.

Wednesday 14 October

14:00
Greg Magolan · Room 5-8

Build and test telemetry as a reusable component, instead of bespoke glue in every repo.

16:20
Greg Magolan · Room 5-8

Agents generate code faster than teams can build, test and review it. The bottleneck of the AI era is proving code correct without unbounded compute.

17:00
Matt Cramer · Room 5-8

Selective delivery: deploy only what actually changed, derived from the dependency graph rather than from a branch diff.

Thursday 15 October

10:00
Borja Lorente · Room 5-8

Replacing sandbox file staging with a content-addressed filesystem on macOS, so sandboxed actions stop paying the copy and symlink tax.

16:20
Jason Bedard · Room 5-8

The Incremental Build Protocol tells a dev server which files changed, not merely that a build happened.

16:30
Cesar Abel · Room 5-8

The 2.x rearchitecture: a native launcher, and genuinely hermetic Python.

16:40
Jason Bedard · Room 5-8

Write BUILD generators as Starlark plugins instead of Go extensions compiled into a gazelle binary.

Friday 16 October

Bazel HackathonCommunity event
09:00–13:00 · Datadog Netherlands, Herengracht 601

The morning after the conference: bring a laptop and a real problem to hack on with the community — no slides, no pitches. Hosted with Datadog. Capacity is limited to 35, so register early, with your full name.

Times are CEST (UTC+2) and, like room assignments, may change. The official BazelCon schedule is the source of truth. Training Day sessions need pre-registration.
