You don't have to
"In the year 5555, your arms are hangin' limp at your sides, your legs got nothing to do, some machine doin' that for you." Zager and Evans sang these words in 1969.

Take better notes, by hand
Researching a topic is hard, because not only are you trying to puzzle together the causes and effects of a given problem or historical series of events, you're also looking out carefully for leads and new threads to pull. Falling down rabbit holes is common—and encouraged—but eventually you need to pull yourself back…

Here be monsters: What do you still need to know when agents do the work?
AI agents write code faster than anyone can read it. What engineers still need: fundamentals, breadth, and the willingness to dive in when it breaks.

If we do not stop to help each other, what do we become?
Yesterday, I received this email as a response to You Can't Vibe Code Love. It's such a remarkable and powerful statement that I asked permission to share it here, in its entirety, with personal information redacted: Hey Jeff, Hope you and your family are doing well. Just jogging

Pre-2022 Books
I noticed that I seem to, subconsciously, gravitate towards books published on or before 2022, and somewhat discount books published after, especially from authors I haven’t heard of.

I’m not a big owner of things, but the best laptop I’ve ever owned is a roughed-up 2015 Thinkpad X250.

There's no point at which turning your brain off will work
In early 2025, I started seeing people turn off their brain as they use LLMs 1 . They would have an LLM take an action (summarize text, write some code, etc.), and just assume that it worked 2 . This generally didn't work in early 2025 and the result was often quite silly.

Maybe comments should explain 'what' (2017)
People say “Comments should explain why, not what.” I feel like starting a flame war today so I’m going to argue that comments should explain ‘what’ too. Please don’t use this as justification to write bad code, okay? Okay. First of all, why shouldn’t comments explain ‘what’? If you need comments to explain what’s…

Alternate clock designs and time systems
A day has 24 hours in it. That's 1,440 minutes or 86,400 seconds. If you wonder why Americans don't understand the need for using the metric system then ask yourself why you use this inconsistent time measurement system.

Work with the garage door up (2024)
One of my favorite ways that creative people communicate is by “working with their garage door up,” to riff on a passage from Robin Sloan (below). This is the opposite of the Twitter account which mostly posts announcements of finished work: it’s Screenshot Saturday ; it’s giving a lecture about the problems you’re…
