I’ve spent so much time, had so many headaches, and encountered so much complexity from what, in my estimation, boils down to this: trying to get something to work on multiple computers. It might be time to just go back to having one computer — a personal laptop — do everything. No more commit, push, and let the cloud build and deploy. No more making it possible to do a task on my phone and tablet too. No more striving to make it possible to do anything from anywhere. Instead, I should accept the constraint of doing specific kinds of tasks when I’m at my laptop. No laptop? Don’t do it. Save it for later. Is it really that important? I think I’d save myself a lot of time and headache with that constraint. No more continuous over-investment of my time in making it possible to do some particular task across multiple computers. It’s a subtle, but fundamental, shift in thinking about my approach to computing tasks. Today, my default posture is to defer control of tasks to cloud computing platforms. Let them do the work, and I can access and monitor that work from any device. Like, for example, publishing a version of my website: git commit, push, and let the cloud build and deploy it. But beware, there be possible dragons! The build fails. It’s not clear why, but it “works on my machine”. Something is different between my computer and the computer in the cloud. Now I’m troubleshooting an issue unrelated to my website itself. I’m troubleshooting an issue with the build and deployment of my website across multiple computers. It’s easy to say: build works on my machine, deploy it! It’s deceivingly time-consuming to take that one more step and say: let another computer build it and deploy it. So rather than taking the default posture of “cloud-first”, i.e. push to the cloud and let it handle everything, I’d rather take a “local-first” approach where I choose one primary device to do tasks on, and ensure I can do them from there. Everything else beyond that, i.e. getting it to work on multiple computers, is a “progressive enhancement” in my workflow. I can invest the time, if I want to, but I don’t have to. This stands in contrast to where I am today which is if a build fails in the cloud, I have to invest the time because that’s how I’ve setup my workflow. I can only deploy via the cloud. So I have to figure out how to get the cloud’s computer to build my site, even when my laptop is doing it just fine. It’s hard to make things work identically across multiple computers. I get it, that’s a program not software. And that’s the work. But sometimes a program is just fine. Wisdom is knowing the difference. Email · Mastodon · Bluesky

Have you thought about doing the opposite of whatever you're doing or considering? It's a really helpful way to test your assumptions and your values. What does the opposite look like, how would it work? It's so easy to get stuck in a groove of what works, what you believe to be right. But helpful assumptions have a half-life, just like facts. And it's ever so easy to miss the shift when circumstances change, if you're not regularly stress-testing your core beliefs. That doesn't mean you're just a flag in the wind, blowing whichever way. But it does mean having enough intellectual humility and creative flexibility to consider that what you believe to be true about your business, about your team, about your technology might not be so. We did this a while back with full-time managers. We'd been working for nearly two decades without any, but exactly because it'd been so long, we were drawn to try the opposite, just to see what we might have missed. So we did. Hired a few full-time managers to help us test that assumption for a few years. In the end, we decided that our managers-of-one culture worked better, but it wasn't a given at the outset. To try the opposite, you really have to believe that you might have been wrong. Because you're wrong about something. I guarantee it. We all are.

For many years now, I’ve been using an old YubiKey along with the free tier of Duo Security to add a second factor to my SSH logins. This is klunky, and has a number of drawbacks (dependency on a cloud service and Internet among them). I decided it was time to upgrade, so I recently … Continue reading How to Use SSH with FIDO2/U2F Security Keys →

RST defaults to high This is an addendum to the article about Espressif’s automatic reset. In that article, we observed the effect of the RST pin on the ESP32-S2-Saola-1RI board: I skipped over this topic quickly, so I am now taking the time to explain how the RST pin manages to have a defined behavior … Continue reading The ESP32-S2 reset pin → The post The ESP32-S2 reset pin appeared first on Quentin Santos.

We build a minimal X86 assembly program, run it… and hit a crash. But that crash is exactly what makes this program worth writing.
