Business4s H1 2026 recap is out. A lot of interesting stuff happened and even more interesting ideas are taking shape! medium.com/business4s-b...

June's reading batch is done — 8 books. The Wandering Inn keeps delivering with Couriers Outbound (4/4), Primal Hunter 14 (4/4) stays strong, and The Programmer's Brain (2/4) proved you can write a whole correct book that's almost completely useless. medium.com/vp-of-books/...

I just published Fintech Engineering Handbook distilled from 6 years of tears, sweat and swears. It’s a free ~25-page resource with various hints and patterns around handling money. Tell me what you think! w.pitula.me/fintech-engi...

Psst, there might be a free slot or two at the current round of mentorship program. Just saying. business4s.org/mentorship/

I wrote my longest article ever. I hope it was worth the effort. medium.com/@w.pitula/sc...

New batch of book reviews. One extraordinary one on critical thinking. medium.com/vp-of-books/...

I'm just gonna just leave it here. I somehow feel it will spread without much marketing. medium.com/@w.pitula/ra...

My current take on how close Claude is to my expected/desired code on different levels: Method bodies: 95% Methods split: 80% Class split: 65% Inter-service architecture: 50% Still a long way to go but I barely modify anything on expression/method level

A new lib from the Business4s ecosystem has just arrived! medium.com/p/84b24281669c

Not the most impressive but complete enough. I need a new thing to waste my time on. Is Dave The Diver good?

I start to think I need to step up my public-speaking game. Or write better abstracts 😅

In 20 minutes I will talk about Business4s at Func Prog Sweden online Meetup! www.youtube.com/live/rFa4Jhg...

I'm looking into Zulip and it seems much more serious and better suited for collaboration than Discord. Why isn't it more popular among OSS communities?

Published first batch of reviews from 2026. Mostly fiction, but good ones! medium.com/@w.pitula/ba...

New Claude usage Hit compiler bug > ask to minimize > ask to search GitHub for related issue. It found one and a workaround.

New day, new article. I've been going full-throttle on agentic software development for the last 2 months and summed up my thoughts. medium.com/@w.pitula/tw...

I’ve finally summed up my 2025 reading. Enjoy! medium.com/vp-of-books/...

Just got my ticket to @scalar-conf.com. Not speaking this time, but the lineup was too good to miss it.

Check out the new Forms4s library by @krever01.bsky.social. It ships with Tyrian 👾 support out of the box, but because it's composable, you aren't locked into a specific UI framework. medium.com/business4s-b...

The Sovereign Tech Fund Invests in Scala: 🔐 security audits 🔧 sbt 2.0 📚 core library maintenance 💪 and long-term resilience for critical digital infrastructure Check out the announcement: www.scala-lang.org/b... 🙏 Huge thanks to @sovereign.tech

New library in Business4s ecosystem! And my semi-rant on scala.js usability. medium.com/business4s-b...

Decisions4s just got support for persistence. I'm still not convinced its a good way to handle business logic, but many people asked if thats possible. Now it is. business4s.org/decisions4s/...

Wild observation: feedback is now more valuable for OSS projects than contributions. I can steer Claude at least just as effectively as avg contributor but I can get real world usage report out of it.

Not bad

Current status: optimized an operational job from 33 hours to 22 minutes :)

Check out what we’ve been up to over the past 6 months 🙂 medium.com/business4s-b...

I posted the last batch of my books reviews from 2025. Double sized (20 positions) because I was lazy. One great book about investment, and a lot of other good ones. medium.com/vp-of-books/...

Some notes from a recent Scala 3 migration I did.

New Workflows4s DevLog is out! youtu.be/xK1vmQhKrAM

Hey @kitlangton.bsky.social does neotype require runtime dependency? @baldram.github.io pointed me to it, and I see it doesn't allocate, but I'm curious if it requires any symbols at runtime at all. I'm asking because if not I could safely use it in my libs without binary compatibility issues.

I am excited, to say the least. medium.com/business4s-b...

🎉Workflows4s is finally out! A Scala library designed for simpler, type-safe, and lightweight workflows. medium.com/business4s-b...

The next episode of Workflows4s DevLog is out, enjoy! youtu.be/KRg42PJW1sA

Workflows4s in one picture

I finally posted what should have been posted two months ago. Anyway, I promise to get back on track with my reading. medium.com/vp-of-books/...

Look at me, I'm a YouTuber now. youtu.be/aDooTCNwU2g?...

A bit overdue but finally there. My feelings about Rust. medium.com/@w.pitula/ru...

🚀 Introducing Scala Highlights – a new quarterly newsletter! Read it now 👉 scala-lang.org/highlights/2...

What's the most creative solution you have implemented in your career (or recently)? (Shameless gathering of talk material)

Nothing to see here, definitely not a great opportunity for Scala devs. www.reddit.com/r/scala/comm...

📚 Just published my 2024 reading summary: 120 books, 1800 hours, and a lot of insights. You will find the top 18 books at the very top of the article. medium.com/vp-of-books/...

People really don't want to listen about documentation 😅🤷

📚 New Batch of Book Reviews! This month’s highlights include leadership insights, masculinity, network science, grimdark worlds, and more. medium.com/vp-of-books/... Non-Fiction: - The First 90 Days: 4/4 - Linked: 3+/4 - Billy No-Mates: 3+/4 - Everyone Communicates, Few Connect: 3/4

Playing with alternative rendering fro workflows4s. What's your preference?

I published the penultimate (I learned a new word!) batch of my book reviews for this year. A lot of excellent positions! medium.com/vp-of-books/...

One of the main design principles of workflows4s is a downward scalability - ability to trim setup complexity based on needs. Currently, it's getting a revamped approach to waking up workflows (e.g. "wait 3 days" or "interrupt if nothing happens for 24h"). It will ...

18 days into learning Rust. It's not a bad language, but I definitely don't want to solve problems requiring it.
