Hi! Long time no see. Hope you are doing well.

I'm Anton. I work on open source and write interactive technical books.

You're receiving this email because you subscribed to my updates at antonz.org/subscribe. If you'd like to unsubscribe, use the link at the bottom of this email.

Since the last issue, I've published four more chapters of my interactive Go Concurrency book:

• Data races
• Race conditions
• Semaphores
• Signaling

Two more chapters to go :)

I've also made an interactive tour for the upcoming Go 1.25 release, plus a separate guide that compares json/v1 and json/v2.

Speaking of new releases, I've published an ultra-lightweight test assertions package called Be. I don't think you need testify/assert to write concise and expressive tests.

Finally, my Redka project — Redis re-implemented with SQL — now supports PostgreSQL. Not as fast as the SQLite-backed version, but still handles 11K+ operations/sec.

That's all for now! See you in a while.

Anton
