+    title: "Empowering WebAssembly with Thin Kernel Interfaces"
+    tldr: "A new OS interface design exposes thin, capability-based kernel primitives directly to WebAssembly modules, eliminating the POSIX translation layer."
+    why_notable: "WebAssembly is increasingly used beyond the browser as a portable, sandboxed compute substrate; this work shows that rethinking the system interface from scratch yields significantly lower overhead and better safety properties than layering Wasm on top of POSIX."
+

+    title: "Revealing the Unstable Foundations of eBPF-Based Kernel Extensions"
+    tldr: "A systematic study exposes how eBPF programs silently break across kernel versions due to undocumented and unstable kernel data structure dependencies."
+    why_notable: "From the Arpaci-Dusseau group, this paper delivers surprising and practically consequential findings: a large fraction of real-world eBPF programs are fragile across kernel versions, undermining the widely held assumption that eBPF is a safe and stable extension mechanism."

+    title: "Pegasus: Transparent and Unified Kernel-Bypass Networking for Fast Local and Remote Communication"
+    tldr: "Pegasus provides a single kernel-bypass networking stack that transparently accelerates both intra-host (IPC) and inter-host communication without application changes."
+    why_notable: "Unifying local and remote fast paths is a long-standing challenge; Pegasus demonstrates that the same RDMA-style techniques can be applied to loopback traffic, yielding substantial latency reductions for microservice workloads with no API changes."

+    title: "Daredevil: Rescue Your Flash Storage from Inflexible Kernel Storage Stack"
+    tldr: "Daredevil bypasses the rigid Linux block layer to allow flash storage devices to express fine-grained I/O semantics directly to applications."
+    why_notable: "The Linux storage stack was designed for spinning disks and consistently imposes unnecessary overhead on modern NVMe SSDs; Daredevil demonstrates that rethinking the kernel/device interface boundary unlocks significant throughput and latency gains that the existing stack structurally prevents."
+
+  - dblp_key: "conf/eurosys/AllisonG0HKN025"
+    title: "Towards Efficient Flash Caches with Emerging NVMe Flexible Data Placement SSDs"
+    tldr: "This paper shows how NVMe Flexible Data Placement (FDP) SSDs can be exploited by flash cache software to dramatically reduce write amplification and improve device lifetime."
+    why_notable: "FDP is a newly standardized NVMe feature; this is one of the first systems papers to demonstrate end-to-end integration with a production-grade flash caching stack, revealing concrete performance and endurance benefits that motivate wider adoption."
+
+  - dblp_key: "conf/eurosys/QiZHH0H025"
+    title: "Chrono: Meticulous Hotness Measurement and Flexible Page Migration for Memory Tiering"
+    tldr: "Chrono introduces fine-grained, low-overhead hotness tracking and a flexible page migration policy that adapts to workload dynamics for tiered memory systems."
+    why_notable: "As CXL-based memory tiering becomes a reality in data centers, accurate hotness estimation is critical; Chrono's approach substantially outperforms existing kernel mechanisms and sets a new baseline for OS-level tiered memory management."
+
+  - dblp_key: "conf/eurosys/YoonOMK25"
+    title: "Adios to Busy-Waiting for Microsecond-scale Memory Disaggregation"
+    tldr: "This work eliminates CPU-wasting busy-waiting in disaggregated memory systems by designing interrupt-driven mechanisms that still meet microsecond latency targets."
+    why_notable: "Busy-waiting is the conventional wisdom for achieving low latency in disaggregated memory, yet it burns entire CPU cores; this paper challenges that assumption and shows interrupt-based designs can match latency while freeing substantial compute, which matters greatly at scale."
+
+  - dblp_key: "conf/eurosys/GentleK25"
+    title: "Collaborative Text Editing with Eg-walker: Better, Faster, Smaller"
+    tldr: "Eg-walker is a new CRDT algorithm for collaborative text editing that is simultaneously faster, more memory-efficient, and produces smaller operation logs than prior state-of-the-art CRDTs."
+    why_notable: "Collaborative editing CRDTs have been considered a mature area, making it surprising that Eg-walker achieves order-of-magnitude improvements across all key metrics; the result, from Martin Kleppmann, will likely become the new reference design for replicated text data structures."
+
+  - dblp_key: "conf/eurosys/LyuXN0ZB25"
+    title: "Ladon: High-Performance Multi-BFT Consensus via Dynamic Global Ordering"
+    tldr: "Ladon achieves high throughput in Byzantine fault-tolerant consensus by running multiple BFT instances in parallel and dynamically merging their outputs into a consistent global order."
+    why_notable: "Byzantine consensus is notoriously throughput-limited; Ladon's multi-instance approach with a novel global ordering layer demonstrates near-linear throughput scaling with the number of consensus instances, a significant advance for permissioned blockchain and critical-infrastructure scenarios."
+
+  - dblp_key: "conf/eurosys/ShengZYWZZPL025"
+    title: "HybridFlow: A Flexible and Efficient RLHF Framework"
+    tldr: "HybridFlow introduces a hybrid dataflow model for RLHF training that co-schedules the actor, critic, and reward models to maximize GPU utilization across heterogeneous cluster configurations."
+    why_notable: "RLHF has become central to LLM alignment yet existing frameworks map poorly to its multi-model, tightly coupled training loop; HybridFlow's design substantially improves end-to-end training throughput and provides a principled abstraction for future alignment training research."
+
+  - dblp_key: "conf/eurosys/YaoLLRCZD0J25"
+    title: "CacheBlend: Fast Large Language Model Serving for RAG with Cached Knowledge Fusion"
+    tldr: "CacheBlend reuses KV caches from multiple pre-computed document chunks and fuses them selectively at inference time, avoiding the quadratic cost of full re-encoding for retrieval-augmented generation."
+    why_notable: "RAG is a dominant LLM deployment pattern, but cache reuse across dynamically assembled contexts is unsolved; CacheBlend's selective fusion strategy delivers large time-to-first-token reductions with negligible quality degradation, directly improving the economics of production LLM serving."
+
+  - dblp_key: "conf/eurosys/YouCZLCDWWHL25"
+    title: "AlloyStack: A Library Operating System for Serverless Workflow Applications"
+    tldr: "AlloyStack is a library OS tailored for serverless workflows that collapses function boundaries within a workflow into a single address space to eliminate inter-function communication overhead."
+    why_notable: "Serverless workflows suffer from high invocation and communication latency because each function is an isolated container; AlloyStack's library OS approach is a principled architectural answer that shows substantial end-to-end latency and cost improvements for real workflow benchmarks."
+
+  - dblp_key: "conf/eurosys/MukherjeeHBMMGA25"
+    title: "CRAVE: Analyzing Cross-Resource Interaction to Improve Energy Efficiency in Systems-on-Chip"
+    tldr: "CRAVE models the cross-resource interference between CPU, GPU, and memory subsystems on SoCs to guide software-level energy optimization decisions."
+    why_notable: "Energy efficiency is increasingly a first-class constraint in both mobile and data center SoCs, yet interactions between on-chip resources are poorly understood at the software level; CRAVE's analysis framework reveals counter-intuitive interference patterns and enables measurable energy savings without hardware changes."
