When type systems bring type checkers to their limit, naming things is still an art, and tests don't target business logic, then it's time for another Applied Go Weekly Newsletter. newsletter.appliedgo.net/archive/2026... #golang

Go 1.26 is out, and what I like most (so far) is the brand new `go fix` command. Forget all you know about the old `go fix` (if you even have been aware of its existence). newsletter.appliedgo.net/archive/2026... #golang

Browsers allow any tab to use the session context of other tabs. Servers have to take measures to protect against the resulting cross-site request forgery (with the help of browsers, to be fair). Go 1.25 makes CSRF protection considerably easier. appliedgo.net/spotlight/cs... #golang

Take notes, but not too many. (Go 1.25 gets a flight recorder.) appliedgo.net/spotlight/go... #golang

WaitGroups in Go will become more convenient and beginner-friendly in Go 1.25, thanks to a small but very effective addition: A Go() method. No more Add()s. No more Done()s. Just one Go() and one Wait(). Nice! appliedgo.net/spotlight/go... #golang

How to leave no traces might be a topic for a spy movie, but software should rather be concerned about how to leave traces—specifically, how to leave the right amount of traces at the right point in time. Like a flight recorder. The latest Applied Go Weekly Newsletter is here!

A surefire way to get into trouble: Attempt to use more resources than you actually have. (Luckily, Go 1.25 becomes much smarter about artificial limits imposed by container runtimes.) The latest Applied Go Weekly Newsletter is here! newsletter.appliedgo.net/archive/2025... #golang
