QCon London 2026: Use<’lifetimes> For<’what>
At QCon London, TrueLayer engineer Ethan Brierley reframed Rust lifetimes using the Polonius borrow checker's mental model: lifetimes as sets of loans rather than regions of code. He built from borrow checker basics through variance and subtyping to higher-ranked lifetimes with serde, showing how the loans perspective makes previously confusing lifetime errors intuitive.

How Datadog Cut the Size of Its Agent Go Binaries by 77%
After the Datadog Agent grew from 428 MiB to 1.22 GiB over a period of 5 years, Datadog engineers set out to reduce its binary size. They discovered that most Go binary bloat comes from hidden dependencies, disabled linker optimizations, and subtle behaviors in the Go compiler and linker.

Sixteen Claude Agents Built a C Compiler without Human Intervention... Almost
In an effort to probe the limits of autonomous software development Anthropic used sixteen Claude Opus 4.6 AI agents to build a Rust-based C compiler from scratch. Working in parallel on a shared repository, the agents coordinated their changes and ultimately produced a compiler capable of building the Linux 6.9 kernel across x86, ARM, and RISC-V, as well as many other open-source projects.

How Meta Ported Million Lines of Android Code from Java to Kotlin
In order to maximize the benefits brought by Kotlin in terms of productivity and safety, Meta engineers have been hard at work to translate their 10 million line Android codebase from Java into Kotlin. One year into this process, they have ported approximately half of their codebase and developed a specific tool, Kotlinator, to automate the process as much as possible.

How to Use Programming Rules and Guidelines
According to Arne Mertz, using programming rules and guidelines helps developers work together, as they result in more consistent and better code. However, using them the wrong way can have the opposite result - code that is cumbersome to read or solves problems in suboptimal or even wrong ways.

Compiler Explorer Provides Insights into Low-Level Android App Optimization
Android engineers at Google added support for the Java and Kotlin programming languages to Compiler Explorer, an open source tool aimed at exploring how compilers work by compiling code in real-time. Using Compiler Explorer, Android engineers can optimize the performance of their apps by observing how the compiler works under the hood instead of using a set of pre-defined best practices.

MLGO Framework Brings Machine Learning in Compiler Optimizations
Google’s new Machine Learning Guided Optimization (MLGO) is an industrial-grade general framework for integrating machine-learning (ML) techniques systematically in a compiler and in particular in LLVM. Compiling faster and smaller code can significantly reduce the operational cost of large data-center applications.

Streamlining the Handoff between Designers and Developers - Travis Arnold at React Finland 2021
Travis Arnold recently presented how JSX and compiler technologies can be used conjointly to make the handoff between designers and developers more efficient. While the ideas presented are not yet implemented in any publicly available tool or library, the ideas of Arnold, who describes himself as a designer/developer, may serve to illustrate possible avenues for improved collaboration.
