I miss those days from early to mid 2000s when compute was still somewhat of a scarce commodity and developers had to understand and learn the whole stack incl. the hardware side to squeeze the most out of it. #ai #enshittification

My grandma's ISP provides her router with #IPv6 by default. Every device in her wireless network has a unique routable address. She doesn't even know or care about what IPv6 is. Let that sink in.

Ok, this #Go function signature is making my eyes bleed! Is this even considered idiomatic?

argghhh! Working with struct tags in #Go can be such a pain sometimes 😫 specially when frameworks decide to use their own custom tags for validation. VSCode does not autocomplete those damn struct tags! If someone has better ideas I am all ears.

Been writing #Go for a year now, I always questioned the validity of generics and wondered why they were so controversial. I have finally stumbled upon my first use case where using generics actually makes sense to maintain compile time type safety while reducing boilerplate. It finally clicked!

I have never been a professional C/C++ programmer by trade and maybe that's why I don't understand this but after doing some beginner level exercises with #rust I don't get all the fuss around how borrower/checker rules make it complicated. Sure, it feels lot more verbose. Even more than #go

Critical thinking, curiosity and the drive to go deeper into the stack to learn something in & out appears to be diminishing as engineers become more dependent on AI generated content. People who were once "engineers" are now becoming "operators"

I've been learning some concurrency in #Go using goroutines so I wrote a really dumb program that launches a workerpool to clone all publicly available repositories of an organization from Github. The obvious natural step next is to feed those repos to a secret scanning tool such as #gitleaks 😂

Most engineers who level up and eventually become executives usually drift away from their engineering grassroots as they become less hands on and focus more on business. But then there are people like Mitchell Hashimoto who still enjoy getting into the weeds and for that he has my respect 🫡

How am I supposed to know which packages (like bufio etc.) contain implementations of an interface (like io.Reader, io.Writer) in #Go? I love the simplicity and beauty of the language but navigating the official docs has been a nightmare.

I'm a tad disappointed with how O'reilly's book "Learning Go 2nd ed." explains the type system in #Golang. They couldn't have explained it in a more convoluted way. But maybe that's just my opinion.

At a first glance using `any` aka. an empty interface{} in #golang seems quite powerful cuz it provides flexibility (just like Python) but since Go is a strongly typed language, trying to to work around it is considered unidiomatic.
