Stumbled across notes from my first @RenderATL (always keep your notes!). From @kishau : "Don't create glass ceilings for yourself by being an ineffective communicator and not being a good storyteller... If you make a technology choice, be able to talk through the alternatives

"None of our top 50 endpoints by throughput can have more than 5% of responses be >500ms" This is a good perf goal. It scopes to the most important parts of the app, is set based on expectations of human users (users can feel >500ms resp), and it's usually quite achievable.

I just released Zeitwerk 2.7. Now, you can define namespaces with manual constant assignments too (think, Namespace = https://t.co/aDrB9gjFO4). To the best of my knowledge, this completes the most important goal of the gem: to fully match Ruby. 🎉 Let me elaborate a bit on why

We're hiring engineer #4 at @scholarlysoft on-site in Seattle. If that's you, let's chat! DMs are open. https://t.co/KtI3dcVwOH

Very exited and proud to be sponsoring #railsconf this year. I’ll be at the open source hackday working on singed, a performance debugging tool! https://t.co/n5V8zMwDqM

I have a long list of ideas I want to work on but not enough time. I do have some money though. Is it time for Speedshop's first employee? If you are: 1. A good writer 2. A solid Rubyist that can build a product from start to finish ... maybe it's you?

We’re at #RailsConf2023!

Our system tests were slow and we couldn't figure out why... turned out it was a 1-line fix! I've written this post for @GustoHQ's engineering blog:

I'm out here saving humanity, and you're are all "scott." smh

Gusto's @techpickles has shipped Singed, a swiss-army-knife tool for getting flamegraphs anywhere in a Ruby application: https://t.co/3MnmmwqDPB It slices, it dices, it profiles: * Blocks * Tests * Requests * Controllers * Command line ... all using Speedscope! It's great.

9% faster response times observed too 👍

Took us, 3 engineers, about 2.5 months to upgrade from Ruby 2.7 to Ruby 3.1

Don't wonder why "some rando in Nebraska" holds up half the internet and then shame them when they don't put out a bugfix fast enough for your liking. We can't narrow the pool of OSS contributors to only people who can put up with this bullshit.

If you work in a company with many 100s or 1000s of employees, the best networking strategy actually lies in plain sight within your company. Here’s how it works:

When I was in my 20s, I wished I only worked for equity (because I was lucky enough to afford it). This industry taught me that everything you "own" as an employee relies on what your managers think, and it can be lost in a single reorg. And it happens again and again.

I realized this morning why the whole "Elon arguing with Twitter devs and firing them" brouhaha of the last few days has hit me on a physical level. It's because, as a senior IC dev, one of the most important aspects of my job is preventing crap like this. (Long 🧵incoming...)

My top two are Gentoo Linux and Rails

👀 I'm looking to hire mid-senior engineers to come join me at a stealth startup tackling SaaS pricing insights! We're a WOC-founded and led company out of NYC and remote-first. RTs welcomed!

Is it me, or is there no actual way to book a Genius Bar appointment online anymore? Every time I’ve tried, I end up in a knowledge-base / online support loop

I'm looking to plan my workshop schedule for the first half of 2023. If your company would be interested in bringing me in for a Rails performance workshop, in person or remote, let's do it! I've got hundreds of happy former students and would love to add some more.
