When we take things out of service, I should write up how they worked
I've come to think that might be a mistake, since there have been more than a one or two times when we've wanted to look back to see how we did something in the past. Now, I think that when we take some significant system out of service, we should strongly consider doing an an 'end of service how it worked' writeup. We should do this right after the system goes out of service, while we still vividly remember all of the details of how it worked, but at the same time it's not going to change (because it's out of service, which is the drawback of writing 'how it works' documentation while something is in service (ask me how I know)).

Don't lose your unreasonable sense of urgency
So don't give up. Every company needs to have someone asking why we can't launch next Monday instead of next month. Willing to accept and underwrite the risks needed to make it happen. And with a stomach for occasionally being wrong, eating the loss, but keep playing.

Domain Sins of My Youth
The point is, many of my side projects could’ve been a subdomain of my personal domain, e.g. instead of:
sideprojet.com
I could’ve done:
sideproject.jim-nielsen.com
Sure, it’s not as cool as the top-level domain, but it’s way cheaper over time.
This is a lesson I wish I knew 15 years ago.

[Repeat] FPS and resolutions we’re used to
Fast-forward to 2023, and I love 60 FPS (or 59.94, or whatever it is). You get so much more information and clarity, especially from streamers who are typing on a console or playing a game. It makes intuitive sense in that context, given we’re used to 60+ FPS on our monitors. But I’ll even watch live action at that framerate and appreciate the extra level of detail.

Shodan's API For The (Recon) Win!
Ever been on a call with a client, and had that "I need a full set of nmap results for that host in 5 seconds" moment? Like when you're trying to scope out the size of a project (maybe a pentest project) and if you *just* had the list of open ports you'd have an answer other than "I'll call you back", because nmap will take 10 minutes?
Well Shodan has you covered, but even that takes a login. Shodan has you even better covered with their API! First, get your API key, you'll find it in your account page.
