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).

Thank you, Kapil! I'm super happy to here that.
Nah, the gems in the latest Applied Go Weekly Newsletter issue aren't hidden; they're in plain sight.

A programming language's version number that corresponds to the last two digits of the year the version is released is like a blue moon, just rarer.

Full disclosure: My terminal is light at day and dark at night. You can definitely trust me after sunset.
Boris Cherny: I hope this was helpful! What are your tips for using Claude Code? What do you want to hear about next? Mike Khristo: dude i thought you could be trusted, but light mode in terminal? Boris Cherny: Engineers literally stop by my desk to make fun of me Mike Khristo: "thanks for changing the field of engineering, Boris Lightmode"
I knew you can't trust those AI bros!

So true, Go combines minimalism with great flexibility in an effortless way, which makes it quite unique among universal languages.
For convenient coding, you need an interpreted language.
For writing fast apps, you need a low-level system language.
Excuse me, that's complete rubbish.

The squares for Curium and Meitnerium from periodictable.com, featuring portraits of their respective namesakes, are presented above a caption "Only two women have chemical elements named after them. Both were born on November 7th." (I'm aware that there was some ambiguity surrounding Lise Meitner's birthday, but Ruth Lewin Sime's biography notes that Meitner celebrated the occasion on November 7.)
Happy birthday to the only two women with elements named after them on the periodic table: #MarieCurie & #LiseMeitner.
As I do every year, I will once again repeat my proposal that November 7 should be International #WomenInSTEM Day!

Yeah, it's a quite unusual use case for Go, but why not?
What if you could write shell scripts like a short story (and use Go code in that process)?

A plane's flight recorder is of little use for determining why the plane has been late. Go's flight recorder, on the other hand, is perfectly suited for that kind of investigation!

In times of AI doing the coding, however, it's equally important to develop skills like troubleshooting, critically reviewing, and architecting software.
(There is no shortcut; however. Without coding skills, reviewing and troubleshooting skills won't come.)
I've learned a lot of languages in my life and used quite a few. I finally settled with Go; it's the closest to "perfect" for me.
If you're starting out, learn new languages by all means! It's like you say: Every new language you learn is a new world view.
Well, on one hand, I'd choose Rust because I know Go already. On the other hand, Go is just right for me, so why should I bother learning another lang...
