Go Weekly

More Powerful Go Execution Traces — Over the last two releases, the Go team has worked to fix and enhance execution tracing, resulting in a 10x drop in overhead and much more scalable traces. These enhancements have spawned two experimental features: the ability to constantly trace execution (i.e. so-called ‘flight recording’) and a trace reader API.

Measuring a System’s Performance with Go — You can run up a benchmark in any programming language, but Go offers some features to make it relatively easy to measure CPU and memory performance, memory usage, and even dig into some of Go’s optimizations. Lots of examples here.

The One Billion Row Challenge (Again!) – From 95s to 1.96s — Gunnar Morling’s One Billion Row Challenge to read and aggregate stats from a one billion line file has caught on! We’ve linked to Shraddha Agrawal and Ben Hoyt’s solutions before, but here’s a very in-depth look at going even further with lots of neat lower level details.

QUICK BITS:

Debugging a Go Bug with Non-Blocking Reads — A case where things acted differently on different operating systems, which led to a quick patch in Go. But, if you can’t wait, there’s a simple workaround.

For Loops and More in Gofor loops may seem like a beginners' topic, but there’s a lot to understanding their full use. How do you handle multiple loop variables? When should you use label breaks? How do range loop semantics affect updating loop structs? Miki shows off some examples.

🛠 Code & Tools

Valgo 0.3: An Expressive Validator Library — Type-safe and extensible validator library built upon generics. “Valgo differs from other validation libraries in that the rules are written in functions and not in struct tags. This allows greater flexibility and freedom when it comes to where and how data is validated.”

Cohesive Stack

Hugot: Hugging Face Transformer Pipelines in Go — A project with a goal of making it easy to run Hugging Face transformer pipelines from Go, without needing to call out to Python or external APIs (note it’s not pure Go – it leans on ONNX Runtime). It supports only ONNX models and a few pipelines so far.

Knights Analytics

Failsafe: Fault Tolerance and Resilience Patterns — A library for building fault-tolerant apps where you can wrap code in resilience policies such as Retry, CircuitBreaker, RateLimiter, Timeout, and Fallback. We linked to this months ago, but as of v0.6, it now can integrate with HTTP clients.

Jonathan Halterman

Hookdeck: The Amazon EventBridge Alternative — Receive, transform, filter, route, and send messages across your EDA with an event gateway for engineering teams.

Konf 1.0: A Flexible Configuration Loader — If you don’t want to be tightly coupled to any one source of configuration settings for your app, Konf might be for you – it’ll work with local sources like files and environment variables, but also with things like S3, AWS AppConfig, and GCP Secret Manager.

Kuisong Tong

Codoworks Go Boilerplate: Prod-Ready RESTful API Boilerplate — An opinionated boilerplate app based around Echo to get CRUD APIs up and running quickly.

Codoworks
