is that so? I have no idea what the % is. Maybe it's very small.

ideally the economy is nice and efficient and is optimized so that everybody can afford to live a decent life while having plenty of money to spare, which they can spend however they want, and which they will in practice spend on lots of ar

Strongly agree.

Better it be a deep dive into developer sanity, a more important but comparatively under-valued metric.

100% agree that this is ideal, the way Github does it is completely godawful and it's a tragedy that so many people have it normalized for them. We did this with Phabricator, although it was a somewhat-manual process, helped along by h

Wow you're right, that was satisfying.

I agree that it _should_ imply expertise, but it doesn't in practice. It bugs me because start using it as a status thing: "how to think like a senior developer", "listen to me because I'm a senior deveveloper"

props for the effort on the footnotes

by ajkjk 2y ago
I've never understood this use of the phrase 'senior developer' like it's evidence of being masterful at coding. In my experience half the juniors and half the seniors were good and the other half were bad. Tenure gets y

I think the basic mechanism is: You have an identity that says you're good at something, responsible, motivated, etc. that identity is the one that talks in meetings, promises to do stuff, signs up for things, etc. This is the part tha

I consider myself an expert in linear algebra and I still find Cayley-Hamilton perplexing. Like it's clearly true but the proofs are unsatisfying It feels like there is an algebraic system that would make it obvious but hasn't be

agree but I am still trying to grok the divine truth as to why exactly that is. What's up with the sandwich products? Why do they work? I guess it is like a change-of-basis for a matrix (PAP^{-1)) but I still don't quite see why,

Ya, as I write in my article, I'm very on board with the "change the curriculum to make more sense" project. I just want to be talking about how to do it in a critical way, rather than just going with the GA way, which requir

by ajkjk 2y ago
So, I've amended the article some since posting it because the main objection I got from a few GA enthusiasts was this idea of the GP as being used to compose operators. Which I had barely noticed the importance of because it's so

Well by "taught in linear algebra" I mean "taught to undergraduates in their first or second year". It is totally bizarre that people learn about determinants, matrix minors, curl, magnetic fields, angular momentum, etc.

by ajkjk 2y ago
Oh yes, strongly agree. They should be taught in linear algebra really.

Those concepts are from exterior algebra which GA is built on. You do not need GA (the geometric product, etc) for them.
801.
by ajkjk 2y ago
I am not sure I understand the plane-based GA model, but I imagine it's that in exterior algebra there is another product that's totally dual to the wedge product (people call it the "antiwedge product" or "regressi
802.
by ajkjk 2y ago
Well the real issue is that the GA proponents do this weird bait-and-switch where they talk about caring a lot about being intuitive and simple, and then they do a bunch of nonsense with the geometric product that makes no sense. It's

by ajkjk 2y ago
yeah, oops, that was supposed to be tongue-in-cheek. No, I'm just a guy who likes math, and I try to write things that make seem correct. I just don't want anyone, like, citing me on something... like, check the work yourself if y

Jesus christ do you think that I'm so small-minded that I'm saying the UI is bad because I biased by knowing the accident happened already? and that I didn't realize I was doing it? No I thought it was shit instantly because

I feel like it's only possible to get excited about software anymore if it's open source and not in the control of some vendor. Not because I care a lot about the ideology of free software, it's just because the way corporati

Yes they are idiots. Well more likely they were cogs in a dysfunctional bureaucracy that is not allowed to do good work because it doesn't allow common sense to drive decision making. So the 'idiot' here is an organization, m

One thing that bums me out about this is the idea that figuring this kind of thing out is what "designers" do. As if there is some special skillset and art to design that a special group of people, designers, do, which we should t

I wonder if it's more about having room for emergency vehicles or for people to pull over if there's an accident without totally stopping traffic.

by ajkjk 2y ago
My reply was not that I did not want to think about it! I thought that the article was bad at thinking about it. I like philosophy, but there's still such a thing as bad philosophy and this is, imo, it.

by ajkjk 2y ago
No, I just thought the article was intellectually lazy and picking on strawmen.
