Long career as a dilettante at Bell Labs Research and Google, mostly building weird stuff no one uses, but occasionally getting it right, such as with UTF-8 and Go.

In 1922 Alfred Stieglitz made a series of photographs of cloudy skies, calling them Equivalents because they matched an emotion or mood he was feeling.

This is my Equivalent for today.

The comments are excellent and measured.
The comment thread here is the embodiment of :lolsob:

There is legitimate promise to LLM-assisted coding, but there are also legitimate risks. Like this. And no one here is malicious!
One of the many joys of using AI for programming is the creation of huge PRs on complex topics that the authors barely understand, but still suggest "because they work". Here's a great example from #OCaml github.com/ocaml/ocaml/...

Kudos to OCaml's maintainers for handling this so gracefully.

As I have said to students nowadays, the most important thing one learns in school is how to learn, and using LLMs completely defeats that objective. The process matters.

You don't use a fork lift the gym. The immediate result—weights up in the air—is not always the key reason to do something.
It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.

Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.
Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

In August I delivered my traditional Go Cryptography State of the Union talk at @gophercon.com in New York.

It goes into everything at the intersection of Go and cryptography from the last year. (Also, bragging t-shirts!)

Last week we visited the Pooseum in Richmond, Tasmania, where I was lucky to have a rumor I had heard confirmed. The abundance of flies in rural Australia is a result of the local dung beetles not liking livestock poo. But you can order the right dung beetles en masse from CSIRO to help.

Proud of myself. Found a typo in my 4th edition of Allen's Astrophysical Quantities. It lists "Standard acceleration of gravity (exact)" in units of m s⁻¹.

I lead a rich life.

It's hard to believe this is real, but I think it is.
And most depressingly: Tyler does not say "What the fuck are you even talking about Sam, and why are you in this job?"
I laughed at loud. These people are so pathetic; our enemies are numbskulls. They will kill us all and still not know hs physics.

COWEN: The stupidest question possible: Why don’t we just make more GPUs?

ALTMAN: Because we need to make more electrons.

Beware. Got pulled aside at the airport because my empty #fountainpen triggered security. It looked exactly like a fountain pen on the x-ray but they were terrified by its threat and needed to see it and disassemble it to be sure it was OK. Security incident barely averted. Sheesh

What is happening at Goddard is absolutely devastating. We are losing history. We are losing an incredible amount of human talent, skill, and knowledge. Rebuilding it will be impossible same for same. Industry can not absorb the people or the equipment. This is undoing space science in the US.
Goddard spacecraft engineer: "I think it just kind of speaks to the atmosphere of the agency and the nation, where people are like, 'Well, laws don't matter for the people at the top anymore.'"
NASA is sinking its flagship science center during the government shutdown — and may be breaking the law in the process, critics say
"There is just a general acknowledgement that a lot of what is happening is illegal…"
