Last Friday was my last (fulltime) day @ Lattice. I'm now moving on to my next adventure! If you're interested, feel free to read my post about why here: But according to Twitter's TOS I now need to do a thread of 6.5 years of learnings. So here we go! 🧵

Well, this sucks. Unfortunately my current startup VStream is shutting down at the end of the month. But don't worry about me. I've already had multiple people approach me about starting new companies. I'll be fine. Just wish I could have done better for my community

Here's one of my rare public hot takes: Github copilot are making developers worse overall. It seems that every young developer is now using it and I get the feeling it allowing them to write code that gets the job done without them understanding _why_ it works.

Bun (written by the amazing @jarredsumner ) has been a game changer for us at @LatticeHQ . Feels like magic just how fast it is. Before Bun we were struggling with our front-end DX under the sheer weight of the amount code we've written. Now it feels like a greenfield app again!

@jaltma IMHO, they will go down. Next year, startups will raise even more money (it's easy right now) and then just pay more cash instead. It seems that employees in general no longer believe in equity leading to payouts and would rather just a high salary.

We at @LatticeHQ switched to 100% pnpm earlier this year for our JS monorepo. Huge savings and we were able to put in amazing tooling that would be impossible with only npm/yarn

I’m hopeful that @npmjs will get its act together quickly, but in the meantime, @pnpmjs is the (monorepo) package manager I now recommend to all @turborepo customers. - faster installs - yarn-like resolutions - expressive filtering - workspace-specific/sparse installs

If you are a mid to senior engineer and you are not inspired or excited about the work you are doing, there may have never been time / demand than what we’re seeing now. Start interviewing. You’ll no doubt find something that but only pays better, but also makes you happier.
