Transition between pre-recorded lunch talks (applause / stream filler)
Day 1 · Oct 13 Day 1 digest · More from this day
A 26-second applause and stream-filler window between two pre-recorded extra lunch talks — Branislav Brzak’s GPU side-channel talk ending and the Railway “SaaS layer” talk beginning — inside the agenda’s 12:15pm-2:05pm Networking Break.
- This window (video 04:15:05-04:15:31, wall 1:02:57-1:03:23 PM) contains no talk of its own. It is livestream filler between two pre-recorded lunch talks.
- The first line, “Thank you all for watching.” at [04:15:05 | 1:02:57 PM], is the closing sign-off of the previous talk — Branislav Brzak’s GPU side-channel research talk (segment 025), which ends at exactly this boundary.
- About 25 seconds of applause and stream changeover followed. No speech from inside the window was transcribed.
- The second line, “People have been saying that SaaS is dead for a while now.” at [04:15:31 | 1:03:22 PM], is the opening line of the next pre-recorded talk (segment 027, the Railway engineer’s “become your company’s SaaS layer” talk, which starts at video 04:15:30).
- Both neighboring talks run during the agenda’s “Networking Break” (12:15pm-2:05pm), so no agenda item covers this segment. It exists only as livestream filler.
Key lessons
Section titled “Key lessons”- A filler cut between pre-recorded talks can hold almost nothing. This 26-second window carries two boundary lines and about 25 seconds of applause and stream changeover. Keep such windows as their own records instead of merging them into either talk.
- Boundary lines serve two records. Segment 025 ends at t 15305 and segment 027 starts at t 15330, so both lines sit on shared cut points. The first closes Branislav Brzak’s talk and the second opens the Railway engineer’s talk; this record keeps them only for context.
- Attribution for a filler window must come from position, not from speech inside it. The manifest lists no speakers for this segment. The closing line is credited to Branislav Brzak only because it lands at the end of his GPU side-channel talk (segment 025), and the opening line to the unnamed Railway engineer of segment 027, whose name the manifest records as not heard.
- Stream filler can be invisible to the agenda. The whole window falls inside the agenda’s Networking Break (12:15pm-2:05pm), so no schedule item covers it. Treat the livestream, not the agenda, as the source of truth for these segments.

Session narrative
Section titled “Session narrative”This segment is applause and stream changeover, not a talk. Branislav Brzak’s pre-recorded lunch talk on GPU side channels (segment 025) ended at video 04:15:05 with the line “Thank you all for watching.” The stream then carried applause and reset while the next pre-recorded lunch talk cued up. Nothing further was transcribed for about 25 seconds.
The next talk began at video 04:15:30. Its opening line, “People have been saying that SaaS is dead for a while now.”, was captured at [04:15:31 | 1:03:22 PM], one second inside this window’s end. That line also appears at the head of segment 027’s transcript, which continues into the Railway engineer’s argument about internal tooling and agents.
Two boundary notes from verification. First, both transcribed lines sit on shared boundaries with neighboring segments (025 ends at t 15305, 027 starts at t 15330), so each line appears in two transcripts. Second, the manifest carries no notes and no speakers for this entry; the attributions above come from context alone, since no speaker is introduced within the window itself.
Speaker details
Section titled “Speaker details”No speakers are credited for this segment in the session manifest.
Branislav Brzak - AI Security Researcher, Stealthium (contextual attribution only). The boundary line “Thank you all for watching.” at [04:15:05 | 1:02:57 PM] belongs to him by context: it closes his lunch talk on GPU side channels in segment 025. His research shows a GPU co-tenant can fingerprint a victim LLM’s architecture and depth with about 97% accuracy and its decode speed with about 99.3% accuracy from timing alone, within a MIG-partitioned H100 and across an NVSwitch/NVLink fabric.

Mahmoud Abdelwahab (identified in the official talk library, not in this transition segment). The boundary line “People have been saying that SaaS is dead for a while now.” at [04:15:31 | 1:03:22 PM] opens this speaker’s lunch talk on becoming your company’s SaaS layer (segment 027), recorded from Edinburgh. The original manifest recorded the name as “not heard”. The official reading edition supplies the speaker attribution.
