Here's my FOSDEM 2026 talk about phantom binary dependencies 👻 — software packages we depend on without realising it, which leads to security and sustainability issues.

Here's my FOSDEM 2026 talk about phantom binary dependencies 👻 — software packages we depend on without realising it, which leads to security and sustainability issues.
*Great* example.
Hey, other companies 👋
@voidzero.dev is giving a good example here. If you need help defining your company's open-source funding strategy, my DMs are open. We need every company to step up its funding game. Let's take care of our maintainers, or the whole ecosystem will collapse.

I wanna say this out loud. A few months ago, I told Evan that @voidzero.dev should stop sponsoring me. I burned out, and I couldn't help Vite as before. But they decided to continue supporting me while I was down. And by doing so, they helped me get back on my feet sooner. Thank y'all ❤️
Just doubled @voidzero.dev 's sponsorship to @patak.dev to $2k/mo. Excited to have you back, and proud to be supporting your work of improving the JS ecosystem.
We have a unique opportunity with npmx. We're building something very special together. I want to give myself the chance to focus on helping steward the project. I'm going to be working as an independent open source developer this year. Support my work and help me focus on npmx long-term 🙏

You can also give back and help sustain the projects you use by creating thoughtful issues (read antfu.me/posts/why-reproductions-are-required by @antfu.me), and helping where you can.
Before talking with your employer, get a good pitch in order. @opensourcepledge.com is a great way to approach it.

Do you like a free tool? Send money.
Do you use a tool at work? Convince your employer to sponsor it. Stop marketing OSS as free stuff to your employer, and treat it as a cost for the company.
You only endanger the OSS project, if you don't give something in return.

It's heartbreaking to see widely-used frameworks like Tailwind become even less financially sustainable due to LLMs.
I appreciated Tailwind's creator sharing his feelings of failure and frustration in an emotionally vulnerable way, and I made a short video to explain how I see the problem.
