Currently also impacted by the Air Canada strike, as my Wednesday flight is likely not going to happen.
Booked a fully refundable train ticket on VIA for Thursday.
There were still a few tickets left for Wednesday and Thursday. Even when things are that bad, people don't switch to train. Quite surprising honestly, i thought i would sell out right away.

RadGame: An AI-Powered Platform for Radiology Education
We introduce RadGame, an AI-powered gamified platform for radiology education that targets two core skills: localizing findings and generating reports. Traditional radiology training is based on passive exposure to cases or active practice with real-time input from supervising radiologists, limiting opportunities for immediate and scalable feedback. RadGame addresses this gap by combining gamification with large-scale public datasets and automated, AI-driven feedback that provides clear, struct…

An ETH-Tight FPT Algorithm for Rejection-Proof Set Packing with Applications to Kidney Exchange
We study the parameterized complexity of a recently introduced multi-agent variant of the Kidney Exchange problem. Given a directed graph $G$ and integers $d$ and $k$, the standard problem asks whether $G$ contains a packing of vertex-disjoint cycles, each of length $\leq d$, covering at least $k$ vertices in total. In the multi-agent setting we consider, the vertex set is partitioned over several agents who reject a cycle packing as solution if it can be modified into an alternative packing th…

The Evolution of Logical Replication in PostgreSQL: A Firsthand Account
PostgreSQL has come a long way from its early days as a single-node database. If you’ve worked with PostgreSQL for a while, you’ll know its journey to robust logical replication was anything but straightforward, shaped by community efforts, creative workarounds, and an ever-evolving need for high availability and flexibility. Having been closely involved in projects like londiste, pglogical, multiple iterations of PGD (BDR) and the built-in logical replication in PostgreSQL itself, I’ve h…
