Reading List
We keep saying that Rust is how we make software safer. In this blog, we'll tackle a real-world vulnerability, 'rewrite it in Rust', and show you the results of our empirical research, both as a high-level overview and a tech deep-dive.
This guide is designed for product and engineering teams exploring how to build their first agents, distilling insights from numerous customer deployments into practical and actionable best practices. It includes frameworks for identifying promising use cases, clear patterns for designing agent logic and orchestration, and best practices to ensure your agents run safely, predictably, and effectively.
Free-standing function call syntax considered kind of suboptimal.
PostgreSQL JSONB efficiently stores semi-structured data using a binary format for direct path access and indexing, enabling complex queries without rigid schemas. By supporting GIN/B-Tree indexes and JSON-specific operators, it balances relational integrity with document flexibility, ideal for varied data models while maintaining transactional reliability.
Lua's simplicity and tables enable rapid development for game logic, but its dynamic typing and lack of compilation can lead to runtime errors in large codebases. Despite challenges, Lua proved viable for a 60k-line game project, though static typing tools like TypeScript or Luau could enhance maintainability.
Claude Code is a command line tool for agentic coding. This post covers tips and tricks that have proven effective for using Claude Code across various codebases, languages, and environments.
A technical deep dive into how the ChaCha20 cipher is taking on AES as the gold standard for symmetric encryption, and a lesson about the power of simplicity in cryptographic design.
SQL stored procedure optimization at scale requires CI/CD performance testing and manual bottleneck analysis, consuming hundreds of annual developer hours. Agoda integrated GPT to automate reviews, reduce approval times, and enable self-service tuning, addressing delays and manual inefficiencies in their workflow.
The article provides an in-depth overview of the Digital Cinema Package (DCP) system, detailing how movies are securely distributed and encrypted for theatrical release. It explains the roles of various components like Key Delivery Messages (KDMs), encryption standards, and the logistics involved in ensuring that digital films are delivered and played securely in cinemas.
LinkedIn built a custom DNS Caching Layer (DCL) to replace NSCD, offering adaptive timeouts, exponential backoff, and real-time fault isolation for resilient DNS resolution at web scale. DCL reduces latency to sub-millisecond levels, provides fleet-wide visibility, and prevents outages through rigorous testing and dynamic configuration management.
We'll explore how we can leverage all cores on a machine with rustc using many crates to speed up compilation.
In the world of DevOps and Developer Experience (DevXP), speed and efficiency can make a big difference on an engineer’s day-to-day tasks. This post dives into how Slack’s DevXP team took some existing tools and used them to optimize an end-to-end (E2E) testing pipeline. This lowered build times and reduced redundant processes, saving both time and resources for engineers at Slack.
Watch, Listen
Join Brian Goetz (Java Language Architect) on a whirlwind tour of recent enhancements and future directions for the Java language with a special emphasis on Project Amber and Project Valhalla.
Learn about all the most important concepts and terms related to machine learning and AI.
The video explains the Model Context Protocol (MCP) as a JSON-RPC framework enabling AI models to interact with external services via structured tool-calling, similar to Language Server Protocol. It demonstrates building WebAssembly servlets and clients for cloud-native automation, focusing on modular AI-driven workflows in Kubernetes/DevOps environments.
