Ory Hydra is a hardened, OpenID Certified OAuth 2.0 Server and OpenID Connect Provider optimized for low-latency, high throughput, and low resource consumption.

Go is a simple and fun language, but, like any other language, it has a few gotchas... Many of those gotchas are not entirely Go's fault. Some of these mistakes are natural traps if you are coming from another language. Others are due to faulty assumptions and missing details.

A lot of these gotchas may seem obvious if you took the time to learn the language reading the official spec, wiki, mailing list discussions, many great posts and presentations by Rob Pike, and the source code. Not everybody starts the same way though and that's OK. If you are new to Go the information here will save you hours debugging your code.

This provides the lru package which implements a fixed-size thread safe LRU cache. It is based on the cache in Groupcache.

Skeema is a tool for managing MySQL and MariaDB schema changes in a declarative fashion using pure SQL.

Work with Semantic Versions in Go

We're building Dolt, the world's first SQL database with Git-like version control. Dolt has a large test suite, partly in golang unit tests and partly in bats, a framework for writing tests that run in Bash and can easily test many interactions with standalone programs.

Testing some of Dolt's features, like standby replication, requires spawning and coordinating multiple processes. Bats and Bash wasn't the right tool for the job. Luckily, Go has great facilities for spawning and interacting with background processes. While running processes from Go is not as concise as running them from the shell, it has robust facilities for error handling and concurrency.

D2 is a modern diagram scripting language that turns text to diagrams.
