More info on the Canadian trend of increasing heat pump installations. I may put together a short thread on our research, decision criteria, and what impacted our ultimate choice. Let me know if anyone would be interested in that information from a somewhat ignorant source :-)

Indoor thermal comfort management: A Bayesian machine-learning approach to data denoising and dynamics prediction of HVAC systems
The optimal management of a building's microclimate to satisfy the occupants' needs and objectives in terms of comfort, energy efficiency, and costs is particularly challenging. This complexity arises from the non-linear, time-dependent interactions among all the variables of the control problem and the changing internal and external constraints. Focusing on the accurate modeling of the indoor temperature, we propose a data-driven approach to address this challenge. We account for thermal inert…

SAKURAONE: Empowering Transparent and Open AI Platforms through Private-Sector HPC Investment in Japan
SAKURAONE is a managed high performance computing (HPC) cluster developed and operated by the SAKURA Internet Research Center. It reinforces the ``KOKARYOKU PHY'' configuration of bare-metal GPU servers and is designed as a cluster computing resource optimized for advanced workloads, including large language model (LLM) training. In the ISC 2025 edition of the TOP500 list, SAKURAONE was ranked \textbf{49th} in the world based on its High Performance Linpack (HPL) score, demonstrating its glob…

A Catalog of Forty-two Heartbeat Stars Discovered in TESS Data
Heartbeat stars (HBSs) are ideal laboratories for studying the formation and evolution of binary stars in eccentric orbits and their internal tidal interactions. We present 42 new HBSs discovered based on TESS photometric data. Their light curves are modeled by using a corrected version of Kumar et al.'s model or the PHOEBE binary model code. Tidally excited oscillations (TEOs) are detected in ten systems, with most pulsation phases can be explained by the dominant being $l=2$, $m=0$, or $\pm2$…

Finished "Far from the Tree" by Robin Benway last night. For me, it was a gripping and absolutely delightful read. I can recognize that I'm absolutely unequipped to judge whether it authentically reflects the experiences of many or few of the people whose situations are similar to the protagonists', but I find myself fervently hopeful for the former, even as I recognize such hopes in the part of people like me can be part of ultimately harmful publishing selection feedback loops. (If anyone reading this happens to have read the book and found it distasteful, I'd love to hear that.) Notwithstanding my probably overcautious uncertainty, I'll definitely be seeking out more books by Benway. At the very least, I really enjoyed her little joining and framing metaphors, and the pacing and plot construction were good, with lots of nicely interwoven implications arising through the buildup, and an ending that left me satisfied (albeit, I'm an inveterate optimist, YMMV).

WANDER: An Explainable Decision-Support Framework for HPC
High-performance computing (HPC) systems expose many interdependent configuration knobs that impact runtime, resource usage, power, and variability. Existing predictive tools model these outcomes, but do not support structured exploration, explanation, or guided reconfiguration. We present WANDER, a decision-support framework that synthesizes alternate configurations using counterfactual analysis aligned with user goals and constraints. We introduce a composite trade-off score that ranks sugges…

Performance Analysis of SAGIN from the Relay Perspective: A Spherical Stochastic Geometry Approach
In recent years, the satellite-aerial-ground integrated network (SAGIN) has become essential in meeting the increasing demands for global wireless communications. In SAGIN, high-altitude platforms (HAPs) can serve as communication hubs and act as relays to enhance communication performance. In this paper, we evaluate network performance and analyze the role of HAPs in SAGIN from the relay perspective. Based on this unique perspective, we introduce three metrics to evaluate the performance, name…

I think I'm done and will step off the soapbox now. I'll answer any other questions that pop up and maybe add to this thread any updates on the install (July 14th) or initial impressions on operating if I think it would be interesting to other HVAC nerds.
