  • Weekly sonic bytes of Go

    Shay and Jonathan are a lot of fun to listen to. I often leave the podcast running in the background while I’m out running errands.

    The format is easy to digest, and I love how careful the hosts and guests are about not drifting into long tangents or straying from the main topics. I also don’t always have time to dig through the hottest Go issues on GitHub, so I use the podcast as a way to catch up.

    Another highlight is how often it features recent blog posts from the Go community, many of whi... more

Talking Points

Recent interactions between the hosts and their guests.

Canada trip, 1.27rc1, `` vs “, and Go in the Gaming industry with Francis J. Nickels III
Q: What are some challenges around running large-scale online games, and how does Riot address them with Go and related tech?
Key challenges include ensuring high reliability, low latency, regionalization of services, DDoS protection, anti-cheat, and rapid release cadences; Riot uses Go for backend services, automation, and tooling to manage these requirements, while adopting a 'games as a service' model with frequent updates.
Canada trip, 1.27rc1, `` vs “, and Go in the Gaming industry with Francis J. Nickels III
Q: How do you use Go at Riot, and what parts of the stack are you applying it to?
Go is used primarily on the backend and for infrastructure tooling, including Kubernetes-based services, ingress traffic handling, and internal tooling to automate processes and improve reliability.
OpenAPI 3.1.0 support in kin-openapi, and a CRITical look at agentic coding
Q: Why did you choose Go over Elixir for Crit MD's hosted service?
The choice is driven by the lean binary size, standard library coverage, and strong tooling that suits a lightweight, secure hosting model, though Elixir shines in real-time and security concerns for shared plan reviews.

Q: What are your impressions of working with Go for this project?
Tomasz explains that Go's rich standard library and tooling support enable a lean, single-binary design for Crit, while highlighting Go's ecosystem and concurrency primitives as strengths, balanced with trade-offs against Elixir for hosting and real-time features.
Builds, Validation, Web3, CORS, Typescript-- wait this is a Go show?! with Paweł Zaremba
Q: What was the motivation behind proposing a separate build version flag for Go, and how does it compare to the existing build VCS flag?
The guest explains that a separate build version flag could allow a separate versioning convention from the repository, but there is skepticism about adding more flags and increasing complexity. The discussion notes that existing mechanisms already support embedding version information, so the new flag might only be useful in specific workflows.
