Transition/applause between lunch talks
Day 1 · Oct 13 Day 1 digest · More from this day
A 21-second applause and changeover window on the livestream between two extra lunch talks — Kim Maida’s Keycard talk ending and Branislav Brzak’s GPU side-channel talk beginning — inside the agenda’s 12:15-2:05pm networking break.
- Kim Maida closed her lunch talk “Your Agent Is a Lethal Trifecta” (Keycard) with a thank-you and self-introduction at [04:01:15 | 12:49:06 PM], seconds before this window opens at 04:01:24.
- For about 21 seconds (04:01:24-04:01:45) the stream carried applause and stage changeover. No speech from inside the window was transcribed.
- The single transcribed line, “Hello everyone.” at [04:01:45 | 12:49:36 PM], is the opening of the next lunch talk (Branislav Brzak on GPU side channels). It sits on the shared boundary and also appears at the head of segment 025’s transcript.
- The extra lunch talks run during the agenda’s “Networking Break” (12:15pm-2:05pm), so no agenda item covers this transition. It exists only as livestream filler between recorded talks.
Key lessons
Section titled “Key lessons”- No lessons apply to this segment. It is a 21-second applause and stream changeover with no talk content of its own. The substantive lessons for the talks it sits between live in session 023 (Kim Maida, Keycard) and session 025 (Branislav Brzak, GPU side channels).

Session narrative
Section titled “Session narrative”This segment is applause and stream changeover, not a talk. Kim Maida finished her Keycard lunch talk at [04:01:15 | 12:49:06 PM] with “I’m the founding GTM engineer and head of DevRel at Keycard, and I really appreciate your time today, so thank you very much.” The room then applauded while the stream reset for the next pre-recorded lunch talk. Nothing further was transcribed until the next speaker began.
Two boundary notes from verification. First, the window (t 14484-14505) overlaps its neighbors by about a second: segment 025 starts at t 14504 (video 04:01:44), so the “Hello everyone.” line at 04:01:45 lands in both transcripts. Second, the manifest carries no notes for this entry; the attribution of that line to Brzak comes from context alone, since segment 025 continues from it into “This talk is about the danger of your LLMs information leak in through shared GPU hardware.”
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 “Hello everyone.” at [04:01:45 | 12:49:36 PM] belongs to him by context: it opens 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.
