CheckMate: Evaluating Checkpointing Protocols for Streaming Dataflows
Stream processing in the last decade has seen broad adoption in both commercial and research settings. One key element for this success is the ability of modern stream processors to handle failures while ensuring exactly-once processing guarantees. At the moment of writing, virtually all stream processors that guarantee exactly-once processing implement a variant of Apache Flink's coordinated checkpoints - an extension of the original Chandy-Lamport checkpoints from 1985. However, the reasons b…

Hi friends! I was just out for a quick hike with my wife. Lovely sunny weather with just some snow at the top. It's weird because I feel so tired. That's also why I haven't been posting for a couple of days. But I'm sure things are going to be better soon!
Enjoy your Saturday!

This image captures a serene, wintry landscape, dominated by a freshly snow-covered path that invites the viewer into a tranquil outdoor scene. The path, edged by the soft, undisturbed snow, meanders gently through a sparse forest of trees, their branches heavy with snow, creating a picturesque winter tableau. The sky above is a vast expanse of subtle gradations, from the lightest of blues to the softest of whites, with clouds scattered across it, hinting at the quiet cold of a winter's day. Th…
This image captures a serene, picturesque scene of a grassy hill adorned with sporadic trees, unfolding against the majestic backdrop of a mountain range. The lush greenery of the hill contrasts beautifully with the deep blue sky overhead, suggesting a clear day without a cloud in sight. The mountains in the distance add a sense of grandeur and wilderness to the landscape, evoking a feeling of tranquil highland scenery. The composition suggests the image could be situated in a national park or …

Mechanical effects of carboxymethylcellulose binder in hard carbon electrodes
Electrodes in sodium-ion batteries endure mechanical stress during production and application, which can damage these fragile coatings, causing performance inefficiencies and early failure. Binder material provides elasticity in electrode composites to resist fracture, but evaluating the effectiveness of binder is complicated by substrate dependency of these films, while conventional cell tests are beset by multiple electrochemical variables. This work introduces a practical low-cost indentatio…
