The podcast reviews recent advancements in the C programming language, particularly focusing on the C23 standard, which marks the first major update to the language since C11. Key features introduced in C23 include the ability to declare variables within control structures, enhanced Unicode support, and improvements to the standard library such as checked integer arithmetic and bit manipulation utilities. The discussion also addresses technical aspects of the standard, such as pointer provenance, the challenges of standardizing new data types like wide integers, and the progress of compiler support for these new features.
In addition to the C23 updates, the podcast explores broader topics related to C, including security considerations and the role of compiler optimizations in identifying issues like aliasing and overflow. It also speculates on the future of the language, mentioning the proposed C2Y standard and ongoing discussions about potential additions such as lambdas and contracts, which are still under consideration by the C standards committee.
13 May 2026 SE Radio 720: Martin Dilger on Understanding Eventsourcing
Recommended: Useful Architectural Pattern.
Event sourcing is a system design approach that records changes as sequential events to ensure historical traceability, uses event modeling for aligning systems with human workflows, contrasts with CRUD architectures, and emphasizes slice-based design, event streams, and practical applications like legacy modernization and workflow simplification.
6 May 2026 Birol Yildiz on Building an Agentic AI SRE
AI agents in SRE leverage autonomous decision-making, agentic search, and lightweight architectures to replace static runbooks, balancing autonomy with reliability challenges, context management, and human oversight in dynamic environments.
29 Apr 2026 Will Sentance on JS Modernization
JavaScript's evolution from a 1995 scripting language to a performance-optimized modern tool balances innovation with backward compatibility through TC39's incremental updates, browser advancements, community-driven libraries, key features like async/await and symbols, engine optimizations, and a design philosophy prioritizing flexibility and user-driven standardization for large-scale frameworks.
23 Apr 2026 Eric Tschetter on Decoupling Observability
Recommended: Telemetry is important, avoiding vendor lockin is even more important.
Observability in microservices emphasizes decoupled architectures over traditional frameworks to address vendor lock-in, data interoperability, and scalability challenges, while balancing unstructured telemetry management, query language standardization, and cross-team collaboration.
