Go's Major Versioning 'Sucks' (From a Fanboy) — Go’s versioning policy beyond v1 is taking a bit of flak from some quarters of the community. To be fair, it’s a hard problem, and how we got here is understandable, and Lane concludes that “Go still has the best toolchain and ecosystem.”

Do Go Modules Have a 'v2+ Problem'? — There’s a naming requirement that modules of version 2 or greater must end in the major version number, e.g. /v2. According to the author, this is causing problems and isn’t well-known (though the official Go blog did cover it here), so we’re doing our bit to help shine a spotlight on it 😁

The Official Go Modules Documentation — I’ve seen some suggestions on social media that people aren’t aware of this official documentation page on Go’s GitHub wiki that covers modules in full. If modules cause you any confusion, this is the place to, well, ‘go’.

How I Packaged a Go Program for Windows and Linux — Sure, cross-compilation is great, but actually packaging for multiple platforms is a different beast. Here’s how one developer tamed that beast.

Optimizing a Code Intelligence Indexer — Sourcegraph allows developers to navigate and search code bases. Indexing those code bases, especially when they are large, is an expensive operation. Here’s how they massively reduced the performance cost for Go repositories.

An Introduction to the Go Client for Elasticsearch — If you’ve got a large amount of data you want to run full text search over, Elasticsearch has probably turned up on your radar. The official Go client now includes features such as retrying requests and discovering cluster nodes and this post digs into how it works.
