Introduction to Go 1.17 The latest Go release, version 1.17, arrives six months after Go 1.16. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language Go 1.17 includes three small enhancements to the l
Introduction to Go 1.20 The latest Go release, version 1.20, arrives six months after Go 1.19. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language Go 1.20 includes four changes to the language. Go

But after reading an introductory book and the language specification I felt like I really didn’t know enough about Go to use it for real world work. I felt I’d probably need to fall into many traps before

The impetus for this post was a question on the Gophers Slack a while back. A fellow developer wanted to know where to find more information on len. I want to know how the len func gets called. People chimed in quickly with a correct answer It doesn’t. Len is compiler magic, not an actual function call. … all the types len works on have the same header format, the compiler just treats the object l
CPU Cache-Friendly Data Structures in Go: 10x Speed with Same Algorithm
CPU Cache-Friendly Data Structures in Go: 10x Speed with Same Algorithm Learn how to optimize Go data structures for modern CPU architectures. We'll explore cache lines, false sharing, and data-oriented design to achieve significant performance improvements in real-world applications. Key Takeaways Cache misses can slow down your code by 60x compared to L1 cache hits False sharing occurs when mult
