I'm writing an article that deals in part with the career of MIT civil engineering prof John B. "Bud" Wilbur, class of '26. Did you or any of your mentors/elders know him? Please get in touch!

I don't know why component manufacturers even bother publishing catalogs on their websites because they almost never have the parts in inventory.

"Oh, our hydraulic actuator meets all of the requirements of your project? You can have it in 15 months."

I feel like I could design my own and spin up a manufacturing line for it in less time.

bmaxv,
@bmaxv@noc.social avatar

@chrishuck sure.

My point was that it's another case, not of "providing service for money" but "providing service for money at a quality so low and pricepoint that is just barely cheaper than what it costs you to do it yourself".

Its a question of what you expect from other businesses.

And that line seems to be "barely functional".

How they operate a business that way, idk, but it seems to work.

chrishuck,
@chrishuck@fosstodon.org avatar

@bmaxv My biggest gripe with modern business is nobody having anything in inventory. It’s all “Just in time” delivery. They all think every company is a John Deere or CAT that buys things by the thousands and plans a year’s worth of production. I’d wager more customers have the one-off demand. If a supplier tells me they don’t have what I need in stock, I generally move on right away.

🌞 400,000 ‘solar balconies’ boost German home energy harvesting capacity

"The solar balcony generates only a tenth of the power output of a rooftop solution, but it is portable if the homeowner wishes to relocate.

👉 Unlike a rooftop system that requires professionals for installation, a balcony solar system consists of panels and a mounting structure, and the assembly can be completed by anyone using the instructions provided."

🤯 World’s largest 3D printer can build a small house in 80 hours

"A single-story bungalow could take a few months to build, but this printer can complete the project in less than four days.

"The university, with a longstanding relationship with the US government, wanted to demonstrate that a 3D printer could print a home with a lower carbon footprint – as the construction industry produces about 37% of greenhouse gas emissions"

"In the mid-1960s, Robert Kahn began thinking about how computers with different operating systems could talk to each other across a network.

It is for this work on packet communication technologies—as part of the project that became the ARPANET and in the foundations of the Internet—that Kahn is being awarded the 2024 IEEE Medal of Honor."

bluegreenandfree,

About a third of the way into the brilliant HOW INFRASTRUCTURE WORKS by @debcha and I appreciate the wonder at energy storage, a subject in which I've been lucky to make a career.

Also very much appreciate her eloquent debunking of the desirability of off grid living. At first the independence sounds like freedom, but in reality it's just doing more work by yourself. (And only so long as your tech functions!) True freedom is what we build together.

@bluegreenandfree Thank you! [And re: energy storage: I feel like I have a lot of conversations that are eg ‘but lithium!’ and I keep saying, “we need to store energy, and there an infinite number of ways to do that — electricity in batteries is just one possibility” Especially when we are talking longer-term energy storage.]

Re: ChatGPT/CoPilot coding:

Boilerplate code is not a thing. Most "boilerplate" code is already covered in a library or package, and it should be used there. Otherwise, there are situational edge cases to be covered.

And unit test code is not boilerplate either. The point of unit tests aren't just to verify, but to explain problems when a failure happens. Unit tests without this are test theater.

AI coding without severe coaxing cannot do this.

@nf3xn@mastodon.social avatar

@madopal We have recently discovered that AI is great at generating trivial unit tests that pass because they don't test anything. But you do get lots of tests, so that's nice.

Alert: long post ✏️

Transmission lines get hotter as the amount of power they are transmitting increases.

Currently, the operator doesn't have real-time information about line temperatures. So, they estimate a safe value, and transmit power based off on that value. ⚠️


However, these magic ball sensors help improve transmission, by reporting exact line temperatures. 🟩

Knowing the precise temperature, the grid operator knows how close the line is to maxing out on its capacity. 🔶


These “magic ball” sensors — which cost about $30,000 each — may sound expensive, but they have already helped to increase the amount of power that could be delivered on a line by up to 42.8%, in one case!! 📈📈📈
