I wonder if you could throw a small microcontroller at the bottom of a canal, powered by water passing through a fan, to hide it. And why you would want to do that.

Water quality monitoring. Communicate back to the surface with ultrasonic pulses.

And in case people think ultrasonic signaling isn’t a real thing, it very much is. In the oil and gas industry, it’s how measurements taken while drilling a hole are sent back to the surface through the drilling mud.

Website design comment: I love the orange/teal theme! Really drawn to the details such as illustrations carrying the orange/teal theme. Inspired me to re-color a project with this split complimentary color.

I personally hate the colors; I don't know if it was vibe coded, but it resembles the browns that GPT loves a lot.

I'm looking at it from a crappy screen, though.

Ok, I forgot about it, that was with dark mode enabled. Without it it's much better.

>In my essay a distribution of one I argued that bespoke software was the original, correct arrangement, that fifty years of productised general-purpose software were a compromise forced by the economics of scarce programmers, and that AI has ended the compromise.

I would also say that productised general-purpose software was an undue bonanza taking unfair advantage of copyright, which shouldn't have allowed so many restrictions on code which is necessary to make devices perform their intended tasks.

Fortunately AI has been able to get started accomplishing some of the much-needed workarounds to these annoying copyright issues, like few humans have been able to do.

Regardless of whether programmers are scarce or abundant.

On a tangent, it sounds like a famous canal, but I would figure there are a number of little-known waterways where there might be a high-performance 21st century PC resting underwater along with some poor soul's bitcoin wallet :(

Earlier quoted context omitted.

Downhole tools used in MWD/LWD do not use ultrasonic frequencies. Drilling is a very noisy environment. The first tool that I used employed a downhole pulser with a surface transducer and operated at about 0.5-1 Hz. That's not ultrasonic. It was a pretty low frequency signal. Data transmission rates limit the volume of information that can be transmitted from the downhole tool to the surface where they are decoded.

Your tool has to set up a pressure wave in the mud column that is detectable miles away from the tool while the well is being drilled.

This is a good recent paper authored by an experienced drilling engineer about MWD/LWD drilling history and pulser designs and data rates that can be expected.

I read about them in Byte Magazine - the names were memorable - Objek - Numerik and a third chip - there were no silicon afaik but jsut emulator circuit boards run by a Sun workstation.

Objekt, Numerik, Logik, Klock, according to Wikipedia [1]

canals have negligible water flow (except during disasters!) so I don't think that'd work very well. They also get dredged occasionally so there's a decent chance anything you leave down there won't last more than a couple of years

> They also get dredged occasionally

And it's fascinating to watch!

It’s crazy what a small group of smart people can achieve if they’re not captive to conventional wisdom.

They got crushed by the commodity curve and Moore’s Law. But still a great story - and thankfully written by a real person.

The author’s idea that the commodity curve is over and that hardware is now cheap enough to make special purpose hardware viable is intriguing. Standardization used to be important because you needed to convince scarce programmers to invest in the platform, but AI has ended the scarcity of programmers so dedicated purpose hardware is more viable than ever.

The "A Distribution of One" argument seems less convincing than the "The Computer at the Bottom of a Canal" one. I'm no expert, but if you've ever read some of the computing press from the time you'll know that custom software was still rather popular well into the '80s: and unfortunately custom software written for in-house use by a non-software company was the classic venue for all the Software Crisis war stories, which probably has a lot more to do with why it went out of fashion than progammer wages on their own. Whether the main problem was the difficulty of extracting requirements from users and management or the lack of sufficiently good software developers, maybe the arrival of LLM software cannons will be what it takes to fix it, but a hae ma doots.
