“Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage to move in the opposite direction.” ― E.F. Schumacher newsletter.appliedgo.net/archive/2025... #golang

Algorithms are precise, LLMs are wobbly, flaky, hallucinating machines. Would you want to have your code call an LLM and process its replies? Sure you would. newsletter.appliedgo.net/archive/2025... #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

Infiltrating a web site through cross-site request forgery (CSRF) becomes harder with Go 1.25. Wait, what? No, protecting a web site against CSRF becomes easier with Go 1.25! newsletter.appliedgo.net/archive/2025... #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

Applied Go June Spotlight catchup rally, part 2: Own Your Errors! In which I praise Go's unique, weird, verbose, and wonderful error handling that won't go anywhere. (Originally shared in the Applied Go Weekly Newsletter 2025-06-08) #golang

I'm catching up with publishing Spotlights! The ones from June are still missing on appliedgo•net. (If you have subscribed to my newsletter, you've already seen them.) Starting with the Spotlight from June 1st: Should you use atomic methods over atomic functions? appliedgo.net/spotlight/at... #go

How can a formula calculate an image of itself? Even weirder, how can this formula calculate an image of everything (as long as the image is a 106x75 b/w bitmap image)? Find out how this formula works and test it out in Go: appliedgo.net/spotlight/tu... #golang

Found this in my parent's attic: An electronic pocket game from 1982! IIRC, I received it as a bonus for subscribing to a magazine. The manual claims the game runs for three months on two LR44 (LR1154) button cells if played for 60 minutes every day. You bet I ordered a pack of cells in an instant!

Few aspects about Go have been as intensely discussed as error handling. Yet, bazillions of proposals for a better error handling syntax have led us nowhere. Consequently, the Go team has decided to pull the plug on error handling discussions and proposals. #golang go.dev/blog/error-s...

sync/atomic has package-level functions, yet every function's documentation recommends using the atomic types' methods instead. Why? The latest Applied Go Weekly Newsletter is here! newsletter.appliedgo.net/archive/2025... #golang

TIL: There are entire books about memory management in C++. Meanwhile, the power of garbage collectors is still under-appreciated. If you want to get shit done fast, use a language with automatic memory management. Micro-managing memory allocation and deallocation is for extreme use cases only.

Final destination: Go? For me, so far: yes. (Another Applied Go spotlight)

I can't stand these AI posts on LinkedIn anymore... About every day, some AI enthusiast predicts that all software engineers will go extinct, and some AI denier ridicules AI as a silly toy for imbeciles. C'mon folks, can't anybody boldly a MIDDLE GROUND? Oh wait, @thorstenball.com did...
