That said, I do think the translation into a physical card game means that kids aren't getting the experimentation and near-instant feedback that they'd be getting if they were doing this digitally.
In order for a kid to "win," they either have to already know, or explicitly be told using words, what all of the commands do. Then they have to hear the parent analyze their solution, and tell them where they went wrong. Picture, however, a different game, played online: A kid has no idea what "sort" does, but when they link the "sort" command to a blob of text, all the lines are sorted in order. Now no one has told them what this command does, but they've discovered it. By playing the role of a scientist discovering these commands, they might actually gain an intuitive understanding of them.
I'm thinking of the board game "robot turtle," where kids needed to create a "program" of commands to move a turtle to a goal. When they did that, they had near-instantaneous feedback: the parent moved the turtle. If the kid mixed up their left with the robot's left, the failure was obvious. But if the game has been re-made so that there was no board, and the parent and kid just needed to talk about whether the turtle would actually end up seven paces forward and three paces to the left -- i.e. doing it all verbally -- it wouldn't have been nearly as powerful.
So I'm not raining on this, I can see this as very cool. But I am having a hard time imagining it's the best way to learn to pipe together commands.
This idea of experimenting and getting instant feedback is just survivorship bias for a certain type of person, not “the way we ought to teach Unix shell”
This view is corroborated by the research summarized and presented in the programmer’s brain by Felienne Hermans.
I think that is a developer's superpower. The poncy term for it is grit. I tell others that the secret to leaning computers is frustration and persistence.
> and then giving up.
Knowing when to stop or change direction is hard.
I've definitely wasted years of work failing to solve something that I eventually had to give up on (most memorably depending on nasty Microsoft products).
But I've also been paid very nicely because I've solved problems that others struggled with.
And I was paid for the failures too.
Maybe Linux commands is a little different but I kinda doubt it. Errors and feedback are the way to learn, as long as you can endure the pain of getting to the correct result.
> As that is not a surprise, since research keeps showing that direct instruction—explanation followed by a lot of focused practice—works well.
Note the "lot of focused practice".
To be honest, it is very strange how hard it is to teach programming concepts, for some reason almost all humans use computers but only 0.1% or so can program them.
I am not sure we have the 'best way' to teach anything computer related.
People develop world model for physics quite early, they know they can pull with a rope but cant push with a rope.
And they get intuition, things that are thrown up, go down, and they can transfer this intuition in the math, because math is real.
For some reason its hard to do that with code. People keep trying to push with a rope, even after studying for many years.
PS: I am trying to teach her neural networks now and am working on this RNN board game https://punkx.org/projekt0/book/part2/rnn.html to fight the "square" dragon. I want her to develop good world model for neural networks, so that she understands what chatgpt is. I just keep experimenting, sometimes things click, sometimes not.
This is nitpicking but I was curious: there are 4.4 million software developers in the US (https://www.griddynamics.com/blog/number-software-developers...). The population is 340 million, 0.1% would be 340,000. You’re off by over one order of magnitude.
Not saying this is the best way, but have you followed any of Bret Victor's work with dynamicland[1]?
one shot result:
you could do the same, or I could give you access to this one if you want.

It's a GUI for constructing and executing Unix pipelines and it shows the output of each step in the pipeline.
At least it was just $5 but I think it's 1000% more fun to actually use a unix terminal with some sort capture the flag kind of game.
I used to randomly set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon Shell to cmd.exe on my daughter's laptop so she can run programs from there, e.g. go the discord directory and start discord from there.
Then I made unix pipes just to help her with https://overthewire.org/wargames/bandit/ and so we can discuss how do you make "programs that do not know how they will be used", e.g. the programmer of "sort" does not know how it will be used, and you can create ridiculous pipe chains with the cards, just for fun.
Of course I made other random tasks, e.g. we take a random book and we start "catting" and "grepping" it
Most of the games i made on https://punkx.org are like that, i am just trying to teach her something and i need a bit of physical help to "get out of the computer"
The only real card game is http://punkx.org/punk0 which is like uno with state and I play it often with friends, and https://punkx.org/overflow/ which is super intense depending who you play with.
That said, I do love to have a bunch of these card sets in a box, out, up in the cabin, for those mountain-side retreats where really, there's nothing actually else to do while the winds howl outside, than to stoke the fire, turn up the lantern, and try to read the freickin' instructions on the very short-sightedly designed, imho, type-set of these card games ..

When little Johnny gives teacher his 2000 line essay consisting of 1998 empty lines flanked by My 2000 line essay and That's all Folks! teacher will give Johnny a 1 or an F (depending on locality, might even be E where silly rabbits banned 'F' scores). But teacher, I played this here game of cards where empty lines did count won't be accepted as valid reasoning.
Started using it last year and being able to type ‘ls | sort-by modified -r | take 5’ feels liberating.
I am thinking of doing a reprint, but tbh shipping is so expensive now, and I there is also USA's tariffs and etc.
