looking back at old 100k+ LOC projects that I wrote with my bare hands back in my prime

@yannschaub haha no, park is no drone zone even. so just helpful human coming to the rescue 🫰

POV: battery running low at coffee shop in the middle of a park in Beijing (15:21)

Problem: forgot charger 🥲

O'rly

[Joshua @JoshuaJansen]

We're in the market for a new transactional email provider. What's the goto these days?

Need multiple sending domains, great customer support (Europe timezones), good DX and of course excellent observability and deliverability.

Postmark still the one? Resend? (Message)bird? Cloudflare's newly launched workers?

NEW: OpenAI releases Privacy Filter, their first open model of 2026! 🤗 Apache-2.0!

It's a bidirectional token-classification adaptation of GPT-OSS, trained to mask personally identifiable information (PII) in text.

At only 1.5B params, it can even run locally in your browser!

[Mike Coutermarsh @mscccc]

Please everyone just use Ruby on Rails and stop arguing

[Joshua @JoshuaJansen]

Same! We've been running this for a week now with a Codex skill running as automation. Same for picking low hanging fruit from @AppSignal exceptions

[Mike Coutermarsh @mscccc]

We have these running daily on our Rails app. This morning it opened a PR to make a composite index more efficient while I was sleeping.

Go set this up at work, you'll be an app perf improving god.

[Joshua @JoshuaJansen]

@yannschaub hahah on brand though

[Nate Berkopec @nateberkopec]

Much, much better benchmark than vague claims I've seen about Ruby "being more token efficient". Neat!

[Nat Eliason @nateliason]

Nearly every ambitious person I know who has dived into AI is working harder than ever, and longer hours than ever.

Fascinating dynamic tbh.

I have NEVER worked this hard, nor had this much fun with work.

I think people are sleeping a bit on how much Ruby on Rails + Claude Code is a *crazy unlock* - I mean Rails was designed for people who love syntactic sugar, and LLMs are sugar fiends.

[Naval @naval]

The solution to anxiety is action.

"I also get some programmers are eager to tune it out. The hype drones on, the fantastical claims are still far off, and there's uncertainty where this leaves the profession. But that's not reason to miss out on this incredible moment in human history!" https://t.co/guMzuZqgMw

[Joshua @JoshuaJansen]

@yannschaub @antonosika so lovable

[Joshua @JoshuaJansen]

+ a dozen other sparks that didn't (fully) materialize.

It's been the most fun year creating since my early days of discovering web dev almost 2 decades ago.

Getting to relearn what it means to build software in this day and age is an incredibly profound opportunity. Isn't it that curiousity that got us into programming in the first place?

So here's to keep vibing and crafting in 2026! 🥂

[Joshua @JoshuaJansen]

Had a lot of fun vibing a little side-project over the holidays: a @Rails log scanner/parser → https://t.co/hJeTbttFjT

Now exploring baking in a little MCP server so agents can start pulling in relevant log context when building/debugging.

[Joshua @JoshuaJansen]

And my favourite: https://t.co/Bj8iiPQHbv → I completely started from scratch and rebuilt the Virtual Office I spent months working on back in 2020 (https://t.co/BPeDNsl9W5). The new version quickly became a daily hangout at @firmhouse, instantly bringing serendipidy and nostalgic vibes.

[Joshua @JoshuaJansen]

The past months, I've been working on quite an ambitious project: a new type of Virtual Office 🏢

There are great solutions out there today, but I think there is room for something that fits better in our remote-first world. Here's my take on what that would look like:
