I'm in Warsaw for #ScalarConf 😍

Micro-library exposing an API for "delimited-continuations" for #Scala JVM, ScalaJS and Scala Native. Extracted from "lampepfl/gears", may be useful for "direct style" libraries that want to be cross-platform. github.com/funfix/con...

Great Lent starts monday, so might as well do a digital detox. I'm getting off social media for 40 days 🙏 Exceptions: ‣ I'm going to post about my attendance to #ScalarConf, a #Scala conference, March 26-27, see you there! ‣ I'll keep writing on my blog and links will automatically get posted here.

Functional programming (#FP) is programming with functions, where a function is a unique association from one set (the domain) to another set (the codomain) (∀ x1, x2, x1 = x2 => f(x1) = f(x2)). Functions come from maths, and FP is not procedural programming. Hope that makes it clear.

I know you come here for professional, grown-up stuff, but you're taking all of this way too seriously. So, here's a love story in 4 acts #cats #pic

Some of the best arguments I've seen against #LLM / #AI use: - undermines experience - redirects seniors away from teaching - have limited & biased knowledge - code has always been incidental for problem-solving - not conducive to truth seeking blog.fogus.me/meta/LL...

Articles talking about “direct style” in #Scala should definitely answer this question for `scala.concurrent.Future`

GitHub Copilot Agent is very cost-effective, for now. 1 prompt = 1 session = 1 premium request = $0.04 (if not included in subscription), and I've seen sessions last for ~1 hour. For complex work you need more prompts, but you can have ~10 hours of work for $0.4 with Claude Sonnet 4.6. #AI #LLM

I tested Claude Sonnet 4.6 via GitHub Copilot Agent. 👍 The good: resulting PR is much better than the previous PR, same topic (which was unusable) 👎🏻 The bad: I did a review with over 40 comments for changes (more than changed files), incl. bugs & security issues #LLM #AI github.com/alexandru/...

“Talk is cheap. Show me the code.” (a phrase once used by Linus Torvalds) can also be used to address online influencers peddling AI/LLM agents. Folks, for all that orchestration and tokens spent, where are the projects and accomplishments you have to brag about?

💘 released sbt 1.12.3, featuring the end of Scala 2.13-3.x bilateral interoperability (aka Scala 2.13-3.x sandwich) while it's popular to discuss the topography of hot dogs and tacos, an oft overlooked sandwich is Wawa hoagie, which is cut only on one-side eed3si9n.com/sbt-1.12.3 #Scala

I reported a #Scala 3 bug, and it was fixed in one day 😀 And this isn't the first time I'm amazed of how fast some reported issues get solved in this repository. github.com/scala/scal...

Project exposing a Delayed Queue, for #Java, #Kotlin and #Scala … a database-powered message queue that can also delay messages, with support for your favourite RDBMS. github.com/funfix/dat...

I wanted to make a dumb joke on soon seeing social networks designed exclusively for AI Agents, but it was already built.

A colleague investigated a unit-test that was mysteriously failing on some dev laptops, whereas it was passing in CI. It turns out it's because #Bulgaria's currency just changed to EUR ❤️ so it depends on how up to date the #Java runtime is. Happy dev/prod/CI divergence day 😜

"Beyond agentic coding" I like VS Code's more recent inline hints, and coupled with the inevitable chat fatigue, I'm thinking the author is right. haskellforall.com/202...

I was looking at a piece of #Scala code today, written ~3 years ago for $work, and I'm in awe of its maturity and elegance. Granted, it was my own code 😀

Hey everyone, apparently it takes $20,000 and zero developers to copy/paste code from GCC & LLVM. That code was already available, ofc, so that money is for whitewashing the OSS licensing and copyright away. Exciting times!

Small update for my Funfix Tasks project — I've added integration with Kotlin's Coroutines. github.com/funfix/tasks...

Not sure if “skills” are useful for AI Agents, but maintaining my own repository makes sense, since I can be in control. This is very much experimental, and may change a lot. #AI #LLM #Scala #Kotlin https://github.com/al...

Devs that avoided learning to touch-type, for more efficient “coding”, are now feeling vindicated, because they are now writing English texts instead. Speech-to-text is getting better though, hang in there!

I dislike the `*>` and `>>` operators from #CatsEffect, because it introduces too many ways of doing things, and because it … doesn't look good for multi-line expressions. Abused by devs and LLMs alike. Similar feelings for `fold` on Either/Option. #Scala

"Scoped Error Capabilities in cats-mtl" I started experimenting with cats-mtl, too. I kind of like the idea of expressing typed errors as givens (implicits). https://youtu.be/cTKWpYMciV8?si=a6KFjHdE7U-_HPrm

TIL this framework for prototyping SoCs is built in #Scala https://github.com/ucb-bar/chipyard

IntelliJ Scala Plugin 2025.3.28 is out! This bug-fix release brings the following improvements: - The JUnit plugin is no longer required to run most Scala test frameworks. - Support for using/given in structural search has been enhanced. - Support for sbt 0.13 projects on Windows is back. #scala

Integrating more AI into #Firefox is good, esp. if they put users in control 🤷‍♂️ Deciding to not implement something as a matter of principle is a political decision. E.g., it shows that Vivaldi, a bloated browser built on top of US tech (Chromium), is European (if you can't innovate, regulate).

The rise of the LLM-prompt engineer highlights how important logic and clarity in communication is. "Garbage in, garbage out" applies to AI-driven development as well. People now write more words, but less. Ironic, as people increasingly outsource their communications & thinking to AI.

#Kotlin's Ktor HTTP toolkit is pretty cool, having everything I need, like: - Multiplatform support; - Cancellation of HTTP requests; - OpenAPI docs auto-generation. https://blog.jetbrains.com/kotlin/2026/01/ktor-3-4-0-is-now-available/

Scala 3.8 is exciting because the standard library was finally enhanced for Scala 3 specific features. For instance, “explicit nulls” are finally usable for me. First screenshot is Scala 3.3, second is Scala 3.8. Compare the types. https://www.scala-lang.org/news/3.8/

it's remarkable that something as small as 1.2b can get this far. it's even correct for one input! it's a slight pity that it doesn't work for other inputs but still

Zuzi is upset, because it's the weekend and she's bored

The ability to self-host stuff is freeing. For example, I'm self-hosting Linkding, so I don't care what happens to services like Pinboard, Pocket, etc. https://linkding.link/ Also, Vaultwarden, so I don't care about Bitwarden's price increasing 🤷‍♂️ https://github.com/dani-garcia/vaultwarden
