The problem was a strange monorepo setup where multiple packages came from the same GitHub repo. Then I tried to switch one of them to my fork. The error message did not help me understand this reality at all; I only figured it out the very

All this time after writing this article, I’m now realizing a better way to sum up the issue: It’s like when you ask “can I go to the bathroom” and the teacher says “I dunno, CAN you?”

I’m not sure other languages can do “quasiquoting” very easily. Like, JS has template strings, but that’s not “quasiquoting” because the string content is unstructured. Lisp, though, can do this quite easily because it can still parse the u

We can use whatever software we want as long as we use the specified hardware (the NI roboRIO), FIRST's latest firmware, and comply with the match system and safety systems that enable and disable the bot at different times. Many teams

In practice we actually do; I had to simplify for the article. We have a few utilities like a `runUntilDone` that make simple sequences easier to write. Example: https://github.com/frc-2175/2023RobotCode/blob/

Especially when people try to impose Enterprise Quality Java on the students, and your project gets bloated with interfaces and dependency injection and config files…all for a single platform with fixed hardware :( When we were still using

autonomousPeriodic is a tick function; we need to keep ticking. If we spent more than our allotted 20ms in a single autonomousPeriodic then the robot framework’s safety systems kick in and disable all the motors.

The only officially supported languages for the competition are C++, Java, and LabVIEW. When those are your educational options...you stick with Java. (We've now switched to Lua, integrated with the official C++, but it's a lot mo

For discussion to happen, someone needs to create and maintain the space for discussion. Nobody wants to visit a forum that’s full of unrelated garbage, and nobody wants to talk in forums they don’t like to visit. The curation is what makes

This was one of my favorite talks from Handmade Seattle last year. It’s so refreshing to see someone look critically at a software market and study why things succeed, instead of complaining about luck or an overcrowded market.

Tunneling can easily happen in any physics setup if things are moving fast enough - and with giant pizza peel hands, the rotation alone was causing things to move too quickly. And in general I don't think it makes sense to use a physic

I loved seeing this talk in person and really enjoyed reading through it again now. I’m kind of fascinated by the longevity of software for simple systems - games like Another World or Monkey Island or even DOOM are well-loved decades later

“We don’t need to make knowledge individually accessible and maintainable”, followed _immediately_ by “humans are actually really good at preserving knowledge”. Who do you think does the preservation? How do you think preservation works?

I want to revisit my LISP interpreter someday because I have a few ideas about how to implement it more simply. The weird thing, which I only realized after the fact, is that it's less like "building a LISP" and more like &qu

It would be great if they could at least bring the runtime to PC so that people could distribute their games more widely - although at that point you might as well have the whole editor too.

I think the Dreams logic system is good at orchestrating high-level behavior, and not actually great at building complex logic. Dreams works not because you can visualize your timers and variables and toggles, but because the underlying gam

I actually did get sound panels for my room, but I apparently need more, because they did a pretty disappointing job. I also need a mic arm that doesn't spontaneously collapse when I move it closer to my face. (Don't buy Blue Yeti

I would love to see someone with electronics experience use Dreams for a while. My total electronics experience is Snap Circuits and Ben Eater videos, so I can't make as rich a connection to electronics as you might hope from an articl

I love the POV style, especially paired with the lack of cuts. Gives me a better sense of everything he's doing in the kitchen - when else would you see how he keeps his fridge or spice cabinet organized?

SO has been wildly successful, the site is consistently fast and reliable, and it doesn't seem like their decisions have significantly held them back during development. None of this sounds "poor-quality" to me.
