At the tram stop just now, right next to some of the best bicycle infrastructure you'll ever see, an American tourist came to me to ask me if the Dutch government was doing anything about "this terrible bicycle problem" we have in the Netherlands. 🙃

He was really concerned to see so many bicycles everywhere. To his American brain, bicyclists were a terrible thing. He said he almost got hit by a bicyclist multiple times today. (Presumably by walking in the middle of the bicycle road. I don't know how else you manage to do that.) 🙃

Exactly one year ago I stepped down from my main responsibilities in the Rust project, because of burnout. Today, a year later, I employ about a dozen full-time Rust maintainers through Hexcat+RustNL. I'm not doing much technical work anymore, but this people stuff is also pretty fun and motivating.

About to get started on a very fun weekend project. :D

So, how is the Men in Rust meetup going? #oxidize

We lowered the ticket prices for RustWeek! Individual tickets are now 199 instead of 249 euro. ✨ Additionally, we added a checkbox for an extra 100 euro discount, bringing the ticket price to just 99 euros for those who can't afford the full price. 💛

We did raise the price of the employer-paid tickets, but also added an option there for a significant discount for those who need it. 💛

RustNL's Rust Maintainer Team has grown and now consists of 14 people, including three interns! ✨️ rustnl.org/maintainers/ Together, these people are either the author or a reviewer of more than 30% of all pull requests on the rust-lang/rust repository:

Of course, maintenance involves many more things than producing and reviewing pull requests. These statistics don't capture many important types of contributions such as mentoring, discussions, meetings, and so on. But they are interesting numbers nonetheless.

I was asked recently about the cost of running a #rustlang conference and why the ticket prices are what they are. We figured we can just publicly share the numbers for RustWeek, in the name of #transparency. :) 1/9

Setting the ticket prices is very tricky, because you have to set them a year in advance, before any sponsors sign up. We only find out after the event if we ran at a loss or profit. This year, we made a very small profit, which we'll spend on our Rust Maintainers Team: rustnl.org/maintainers/ 8/9

Those are roughly 250 corporate tickets (~410 euro after tax), 300 individual tickets (~190 euro after tax), and 100 student tickets (~30 euro after tax). Accounting for the various discounts (early bird, discount codes, etc.) and overhead, this leaves us with roughly 140k. 6/9

This adds up to roughly € 280k for just the two conference days. (The total for all of RustWeek is ~€ 400k.) The money we get from sponsors covers roughly half of the costs. The other half has to be covered by tickets. 4/9

RustWeek has many subevents (conference, hackathon, unconference, workshops, Rust All Hands, etc.), but I've tried to extract just the two day conference part of RustWeek 2026: 2/9

Now I can finally commit Rust code crimes legally. 😌

More serously, this machine is magic. It somehow cuts wood without charring the edges?
