On the contrary, I've sat on Ivy League tenure panels where humanities members intoned solemnly about H-indices, oblivious to the differences in value of the Lira and the Pound. I also consider much of baseball statistics to be junk sc

I just went to set up a hard limit on several accounts. There is email notification. The only actions stop individual services on individual Amazon server locations. There is no global "DROP DEAD" action freezing my account and my

I fell briefly in love with Hammerspoon, but stopped using it. My MacOS automation is now my QMK keyboard calling Alfred workflows; I use Yabai for window management. I admire Lua, but ran into some sharp edges learning to program in it. St

My father joined Kodak out of college, in 1951. A classmate who interviewed the same day ended up running the place. My father helped a senior programmer automate dozens of jobs, chemically testing their film processing plant. For this he w

I went down the QMK keyboard rabbit hole a few years ago. I ended up with four Leopold FC660C keyboards with topre switches and Hasu QMK controllers, and a closet full of unused mechanical keyboard alternatives I should sell. I never took t

My father's last intelligible words were "I want a pill." My mother understood this request, but we could not act on it. A year later he stopped swallowing. My mother polled the family, and the consensus was to try intravenou

That's his hope. He doesn't want to live as our father did.

After watching our father die from advanced dementia, my brother established instructions that no one is to feed him. If he can't bring a spoon to his mouth unassisted, he would like to stop eating. He works at a hospital, so I believe

Lean is getting the most math buzz of late. The HoTT people instead use Coq, which has to be adapted to their purpose. The differences could be its own thread. I love how you allow that dependent types are now "vanilla"; perhaps m

Proof assistants such as Lean are inching their way into the mainstream. Ideas from topos theory, higher category theory, and homotopy theory are all running together: https://homotopytypetheory.org/book/ I'd argu

"Undo" killed the typewriter, the rest is a bonus. Algorithmic support will kill journals. How do you rank these apps, if one wants some degree of algorithmic sophistication?

Thank you. I have a career of scanned math research notes, in felt-tip color on 32 lb laser printer paper. Teaching through the pandemic forced me on to an iPad Pro and Apple Pencil. I quickly tired of the primitive Notability interface, an

Actually, making my own notation is how I start puzzling out any problem. When one reformulates a problem, the appearance keeps changing but the problem is still there. It often takes multiple reformulations to "see" a problem, un

Before my first vaccine dose I asked a former student (who admitted Mt Sinai's first case, and watched countless patients die) about my vitamin D and Clemastine regimen. I didn't want to interfere with the vaccine. "No good d

I'm a math professor, and my students find it revelatory to understand math as I talk and draw. Math notation is not math, any more than music notation is music. Notably, the Beatles couldn't read sheet music, and it didn't h

I'm a mathematician, but I don't really understand Gödel's incompleteness. I've recently been reading everything I can about proof assistants such as Coq and Lean, and Homotopy Type Theory and such. My lay understanding

Yes! Parser combinators extended to typed trees, with an efficient syntax, would be a great basis for a programming language. Macros would be a primary application rather than strapped-on as they are now in every language. Another clue that
