Hot take — this software pattern is bad and stupid: ./models/ ./views/ ./controllers/ The reason is that code is best designed and organised based on encapsulation, i.e., components with well-designed APIs getting composed into bigger components. And MVC leads to the antithesis of that.

“New Year, Old Me” alexn.org/blog/2026/01...

my hot take is that I don't think it's this website specifically that's toxic. the Circumstances are toxic and nobody really knows what to do about it so they come online and scream. and if I may offer an alternative: actually going outside and screaming feels better.

My December Adventure detoured into an implementation of IndieAuth. I need an authenticated section to process the pending Webmentions before they're made visible to the public. Instead of maintaining my own credentials, I wanted to stay in the IndieWeb spirit and authenticate against my own […]

Yesterday @bootsmcgoot.bsky.social and I saw some techbro giving “30 pieces of advice for people under 30” over on Twitter and it was all grind culture bullshit. As adults of 38 and 43 respectively, we compiled 30 pieces of advice that people under 30 won’t have heard before:

Yearning for instant gratification is the root of all evil, in software development, and in life.

Software devs should have a culture of aggressive upgrades of dependencies. Better to take the pain in small doses, it highlights problems faster (problematic deps to be dropped), it keeps the InfoSec department happy, and it's fighting decay.

OH: Internet outages are getting more common (AWS, Cloudflare) and at the same time, LLM-use is now highly encouraged by corporations. Coincidence?

Microservices became popular due to prevalence of dynamic languages and unhealthy engineering practices, because in such conditions, monoliths collapse under their own complexity.

For me, the biggest #Scala 3 improvement by far is the ability to just put functions in a file without wrapping them in an `object` AMA

I'll be at #ScalarConf 2026 (March 26-27) in Warsaw, with a talk titled: “Type Classes (in Scala 3)” #Scala #Scala3

My son, today, used ChatGPT to translate a Romanian text in English. It did a better job than Google Translate. 2 days ago he asked for a solution to an algebra problem. ChatGPT gave him something complicated, that he could then simplify and apply elsewhere. Cults exist, but Neo-Luddism is one too.

LinkedIn this past week: “This Cloudflare outage has created some of the dumbest takes I've ever seen 😭” … Then proceeds to add to the pile of extremely dumb takes.

Software engineers, especially before saying extremely dumb shit online, should be required to read books like “The Design of Everyday Things” to understand that bad UX is a choice. By making mistakes easy, those mistakes will be made, even by knowledgeable people: en.wikipedia.org/wiki/The_Des...

Clippy can prevent the use of specific methods when they're added to a project's clippy.toml configuration file: disallowed-methods = [ "std::result::Result::unwrap" ]

On people triggered by programming language critiques: People are too easily triggered IMO, but also, I want to turn the Internet back into a giant flame war between geeks comparing Programming Languages and Operating Systems, because that's way better than whatever the hell this is.

“Like comparing apples and oranges” I never liked the phrase, because they are both fruits, with calories, fructose, vitamins, I like them both, and I often have to pick between them for what to eat, depending on my mood alone. You can make both apple juice and orange juice, etc. 1/2

You know that Result::unwrap() from #Rust that just crashed Cloudflare? It wouldn't have happened on the JVM / #Java because its exceptions typically get caught. Just saying 🤷‍♂️

“Programming Languages in the Age of AI Agents” In the age of “AI” Agents generating the code, is your programming language choice still relevant? Or will we just converge on using the top 5 languages, as that’s what the “AI” trained on? #AI #FP #Opinion #Programming alexn.org/blog/2025/11...

In #Java try-catch-finally can ignore returns, mask exceptions, and breaks the interruption protocol. alexn.org/blog/2025/11...

Programming languages influence chosen solutions. To see, for example, how #Scala influences API design, look no further than the Decline library for CLI parsing. github.com/bkirwi/decline

“On Scala, Functional Programming and Type-Classes” (2012) I wrote this article 13 years ago. I'm so glad I wrote it, it's basically a time capsule containing everything I saw in #Scala that made me stick with it. alexn.org/blog/2012/11...

“Scala vs F#” 🔥🔥🔥 Which language leans more towards functional programming? In this binary choice, people have perceived F# to be that language, due to its ML roots, but I have a different perspective… #FP #Scala #FSharp #JVM #dotNET alexn.org/blog/2025/11...
