Anthropic's AI microscopy research unveils how language models like Claude think, including planning ahead in poetry and using shared concepts across languages. It also identifies reasoning failures and multi-step processes, enhancing transparency and reliability in AI systems.
MCP enables vastly more resilient system integrations by acting as a differential between APIs, absorbing changes and inconsistencies that would typically break traditional integrations. With "the prompt is the program," we can build more adaptable, intention-based integrations that focus on what needs to be done rather than how it's technically implemented.
The article introduces PostgreSQL as a powerful database management system capable of handling concurrent users while maintaining data consistency through trade-offs. It demonstrates these concepts by building a basic booking platform using Ruby and SQL to explore transaction interweaving and potential anomalies.
A pragmatic guide for Software Engineering leaders.
Searching through error data efficiently is critical for developers using monitoring tools. At Rollbar, we recently completed a significant overhaul of our Item Search backend. The previous system faced performance limitations and constraints on search capabilities. This post details the technical challenges, the architectural changes we implemented, and the resulting performance gains.
In this post we will explore the potential of WebRTC for remote control and how to achieve sub-100 millisecond latency.
Scott Mitelli humorously discusses the realities of on-call responsibilities for engineers, highlighting the lack of industry standards and the varying degrees of pain involved, from simple fixes to unresolvable outages. He uses the fictional character Alex to illustrate the often-unrealistic expectations placed on on-call engineers.
This article explores the 30-year evolution of PostgreSQL's buffer manager locking design, from a simple monolithic lock to finer-grained controls and atomic operations, enhancing concurrency and performance. It highlights the key changes introduced in versions 6.5 to 9.6, emphasizing iterative optimization and the importance of choosing appropriate algorithms for concurrency.
