File System I/O benchmarks of major Sandbox vendors
Honker
Durable queues, streams, pub/sub, and time-trigger scheduling on SQLite. One file, zero servers.
Cross-Harness Agentic Memory
Supermemory built a ~99% benchmark ensemble to prove the benchmarks are gameable.Letta scored 74% on LoCoMo with just a filesystem. No vector DB, no graph.

turbopuffer: fast search on object storage
Inaugural blog post about the development of turbopuffer, a search engine that uses object storage and SSD caching for cost-effective, low latency search. This post describes into the motivation behind its creation, its unique architecture, and how it significantly reduces costs for large-scale vector searches. Discover how turbopuffer is transforming search infrastructure for companies like Cursor and Suno, offering a scalable and reliable solution.
Compiling Models to Megakernels
Fine-grained synchronization, deep pipelines, and zero kernel launch overheads, automatically.
anthropic-experimental/sandbox-runtime
A lightweight sandboxing tool for enforcing filesystem and network restrictions on arbitrary processes at the OS level, without requiring a container.
DuckLake Architecture Deep Dive
DuckLake is a next generation data lakehouse and open table format. It is significantly simpler and faster than Apache Iceberg or Delta Lake because it uses a SQL database for storing the catalog and metadata. This post covers an architecture deep dive with a detailed Q&A section. DuckLake consists of 3 components: storage, catalog, and compute. Each can be scaled independently, hosted locally with ease, and deployed to the cloud for production. MotherDuck offers managed DuckLake lakehouses for additional simplicity and performance.
LiveStore: SQLite-based data layer for local-first apps
Introducing: LiveStore - the client-centric, local-first data layer for high performance applications.
JuiceFS - Open Source Distributed POSIX File System for Cloud
JuiceFS is a cloud-based high-performance distributed file system, based on object storage and database to achieve data and metadata separation architecture, easily carrying tens of billions of file storage, to meet the random read performance requirements of big data, AI, autonomous driving, gene sequencing and other massive data.
