Quote of the Week
“The best performance improvement is the transition from the nonworking state to the working state.” — John Ousterhout
Reading List
The article explains that LLM applications should be designed to operate with only the minimum permissions needed, following the principle of least privilege, to reduce risks associated with their unpredictability and lack of judgment. It presents a model where the permissions for any LLM action are defined by the overlap between the user’s permissions, the LLM’s permissions, and the specific task’s requirements, ensuring LLMs cannot access data or perform actions beyond what is authorized.
Use OPA to enforce Kubernetes policies with precision and keep your clusters secure, consistent, and under control.
Patreon’s frontend team overhauled its internationalization system by replacing legacy tools, migrating 10,000+ code call sites, switching vendors, and cutting build times and bundle sizes dramatically. Guided by four untranslatable words, the project emphasized thoughtful architecture, linguistic nuance, and Kaizen-style incremental execution to deliver a scalable, inclusive localization framework.
Jane Street engineers discovered a rare, intermittent NFS Kerberos authentication bug—dubbed a “Higgs-bugson”—that caused file-copy failures (-EACCES) due to mismatched sequence numbers when retransmitted requests were processed. Using eBPF tracing, custom FUSE test setups, and a Wireshark plugin, they tracked it down, reproduced it via delayed packets, and submitted an upstream Linux patch to properly cache and verify sequence numbers as per RFC2203.
How targeted improvements helped us speed up bulk data loads and complex schemas.
Reflections on what I’ve learned about information retrieval in the last two years working at Weaviate.
How to run large meetings.
The article argues that standalone tools should be shipped as static binaries using compiled languages like Rust or Go, rather than as scripts in interpreted languages, to avoid dependency bloat, simplify installation, and enhance reliability and security. Compiled static binaries require no toolchain on the user's machine, reduce disk usage, and are less prone to breakage or vulnerabilities caused by dependency changes or removals.
Watch, Listen
This talk outlines key engineering patterns for building robust, production-grade AI agents. It emphasizes that most successful agents are primarily software systems with carefully integrated LLM steps rather than fully autonomous entities. It presents twelve practical factors, such as owning your prompts, managing context windows, and unifying execution and business state, that help developers create more reliable, scalable, and maintainable LLM-powered applications.
Shopify's Head of Engineering, Farhan Thawar, shares how the company is using internal LLMs, unlimited AI tokens, and custom tooling to figure out how to use AI tools more efficiently - faster.
The video discusses the persistent $500 billion challenge of data integration in large organizations and introduces TaxiQL, a semantic query language designed to let users access data across disparate systems without worrying about field names, APIs, or storage formats. Marty Pitt explains how TaxiQL uses semantic types to decouple data producers from consumers, aiming to automate and simplify the complex, costly process of stitching together custom and legacy systems.
