SevenDB is a reactive database extending DiceDB with deterministic subscriptions, bucket-based sharding, and compute scalability. It uses the RESP protocol for Redis compatibility while adding first-class subscription operations and features like durable outbox delivery and emission reconnection for reliable, scalable reactive applications.
This article explains how to efficiently multiply matrices when their parameters are distributed across multiple accelerators like TPUs and GPUs. It introduces a notation system using device meshes and sharding assignments to describe how tensor dimensions are partitioned across physical hardware, enabling scalable training of large language models.
VoltDB is a commercial in-memory DBMS offering ACID-compliant NewSQL functionality optimized for OLTP queries with distributed architecture via sharding and replication. Originated from the H-Store research project at Brown University and MIT, it launched as a Boston spinoff in 2009 and now exists in both commercial and open-source versions, though the original source code is no longer publicly available.
DeFi discussions on X highlight developments in decentralized finance infrastructure and token performance. Starknet's Garden bridge enables BTC bridging and asset swaps, Pi Network hints at upcoming DeFi improvements, and UNI token surges 205% while analysts discuss scaling solutions like NEAR Protocol's privacy and sharding capabilities.
A developer critiques an analyst's explanation of a MultiversX smart contract exploit, arguing the root cause was a missing state revert after error checking—a common bug pattern—not a flaw in the chain's sharding design. The critic calls for a retraction and demands the team provide a full post-mortem on the breach.
