If you leave it turned on. TFA says this user had turned it off.

All major Common Lisps support tail call optimization with proper declarations, with the exception of ABCL because it runs on the JVM.

And those declarations are all identical or almost identical, so it's easy to write an implementation-specific macro to guarantee TCO if you need to do so.

Some algorithms are easiest to express and read with looping constructs. For those algorithms, use looping constructs. Other algorithms are easiest to express and read with recursion. For those, use recursion. You shouldn't be afraid of recursion just because ANSI doesn't say TCO is guaranteed. You should be afraid of it if your code needs to run on ABCL, but otherwise, recur on.

I have some Trinitite. It's easy to obtain. You can buy it in rock shops, especially in the Southwest. Back in the day, when they opened the Trinity site to the public a couple of days a year, there was no prohibition on collecting Trinitite. That's why rock shops have it.

They still open the site to the public one or two days a year but they won't let you collect Trinitite any more. You can walk on it but don't try to put it in your pocket or a person with a gun will pull you aside for a chat.

There's not much public access to the sites in Nevada; at least until the DOE resumes their bus tours and they're even more hard over about not letting you pick up anything.

Git is extremely predictable, but only after you thoroughly understand it. Until then, it seems to surprise you often and every time it happens you think you've lost data. Many times I've had collaborators who said "git ate my files" and I can usually get their files back in a few minutes. This makes them hate git because they cannot use it without having me on call, and they cannot be bothered to learn git thoroughly themselves because it's too damn hard.

The scientific consensus today is that the evidence supports the idea that not all the dinosaurs died out when the Chicxulub comet struck 66 million years ago. The ones that could fly or quickly learn how to fly survived and even thrived, and their grandkids are in your back yard right now.

When the show came out I thought it must have been created by one of my classmates because the title is so arcane. Turns out it wasn't but the show definitely captures the vibe of computing in Austin and Dallas in the 80s.

Everybody knows calculators and spreadsheets are adjuncts to skill. Too many people believe AI is the skill itself, and that learning the skill is unnecessary.

People out of work don't either.

Even people with jobs don't go to FB or Instagram hoping to read AI-generated slop.

Meta is about to find out all the above the hard way.

I've done many USA cross-country trips in a Tesla. Chargers are a non-issue if you stick to interstate highways. I often don't, which means I have to do some advance planning. I find that fun. Others might not.

But if I were in the market for an EV today I wouldn't buy a Tesla. It's a great car but until the Musk family is no longer part of the company I won't buy another one or recommend them to others.

They can't brick cars with bad antennas. They have to allow for cars that drive into tunnels or that are used in areas with no cell service.

They could choose to throw up increasingly annoying messages if the car hasn't phoned home for some time. Tesla does this if you haven't updated your software in a while but the screens are pretty easy to close and ignore.

Assuming you really need a sinewave at the output at all. DC output UPSes are the most efficient way to go if you can bypass the switched-mode power supply at the input of your equipment. Which most equipment has these days unless AC motors are involved.

The Luddites were all for saving labor, but not if enshittified products and slavery to unreliable machines were the price.

Sounds pretty familiar to me.
