Falling in love with flight in the 1960s, I grew up surrounded by British culture, including an obsession with the Second World War’s aircraft and their exploits.

I now have deeply mixed feelings about “warbirds” as a hobby, but I can’t deny that when I spotted the Horten IX / Ho 229 jet-powered flying wing for MSFS Flight Simulator, I felt a massive pang of nostalgia for my more innocent boyhood when such things were wondrous inventions.

@raganwald I live in Tucson where there's a pretty big air force base. I have precisely the same mixed feelings when I catch the weirder aircraft out in flight training, like the V-22 Ospreys. "Ohh those are so cool" followed by "Uh, this is all so not cool"

whenever i see posts about the past like “we didn’t know then that we were living in a golden age” (e.g. about the 95-00s-era web) i wonder what now is the golden age of, from the perspective of our nostalgic future selves

scheidegger,

@chrisamaphone Anything that makes our future self become nostalgic for the present will be necessarily bleak, so I apologize for the extra-bleak answer. I think food is a good bet. Food has gotten so much better in the last ~30-40 years in large part because of global logistic networks that might not hold up well if climate+peace continues to go in the direction we're heading.

I don’t know what triggered this, but for the last few days I’ve been inundated with recruiter cold calls and cold texts. Every single one has been generic, no sign they know my name, or experience, or are calling about a specific job.

I’m perversely tempted to answer just to discover if it’s a garden-variety recruiter, or a scam like pretending they’re a temp agency and asking me to sign up with my banking details so they can “expedite my pay.”

Embattled Harvard honesty professor accused of plagiarism

Academic chapter and two books authored by Francesca Gino appear to copy from sources including student theses, blogs, and news reports

(Note: she's a Harvard Business School prof. So nothing to see here, just MBA prof providing a role model for her students when they graduate.)

@cstross I don’t know how much you’re following her saga, but it is so, so much worse than just that.

Harvard did an internal investigation and, um, she sued the people who pointed out that a lot of the data in her honesty papers looks fabricated. I couldn’t make this up if I tried

TIL that in IEEE FP, -0.0 + +0.0 = +0.0

https://alive2.llvm.org/ce/z/jPi8ZV

scheidegger,
@scheidegger@mastodon.social avatar

Honestly, for the typical FP bullshit, this is better than I expected:

>>> (-0.0) + (+0.0)
0.0
>>> (0.0) + (-0.0)
0.0
>>> (-0.0) + (-0.0)
-0.0

Looks like they went for "preserve commutativity" instead of "preserve existence of identity"

Is the unchecked spread of AI the internet's equivalent of Kessler syndrome?

scheidegger,
@scheidegger@mastodon.social avatar

@gvwilson

have you read this? https://arxiv.org/pdf/2305.17493.pdf

The dynamics are not the same and not quite as bad; kessler is exponential on number of satellites, and model collapse is "just superlinear" (looks like n log n from my not-very-close-reading).

Still, yes - we actually understand what's going to happen and it's Going To Suck.

There's a pattern that academics engage on all the time which absolutely enrages me.

It involves setting up an asymmetric game, where

person 1 mass-emails persons 2..N who have either of two moves, A or B.

Move A takes some effort ("fill in this survey", or "tell us about your project so we can feature it in our own work")
Move B takes none: "fuck off my TODO list, tyvm".

The problem here is what happens when you analyze this game. (1/n)

scheidegger,
@scheidegger@mastodon.social avatar

Move B makes player n look slightly worse than all the other players (your work doesn't get mentioned on someone else's website), so player n feels bad and does A.

Move A benefits person 1 greatly - the project will be successful!

But successful on whose backs? The answer, of course, is on the backs of all the Move A players.

But move A players didn't choose to engage in this; they just got a item in their TODO list put in by someone else.

This is weaponized feel-bads + community engagement

now that most of the major conferences i submit to have anywhere on earth (AoE) deadlines i think somebody needs to mention that these are "courtesy" deadlines, to give you a few hours of grace so you're not having to wake/stay up at odd hours to turn something in just because you're in an inconvenient time zone. you can work until 6 AM your time or whatever, but you shouldn't have to, and you will regret doing so. maybe not this deadline, but some deadline, and soon.

I did that thing where I tried to write a blog post and ended up writing a extension. As one does.

And then I wrote a blog post about the extension instead of the blog post about the other thing. Oh and I also didn't finish the draft blog post I've been sitting on for 5 months, either.

But hey, here's a neat Quarto shortcode for adding a date anywhere in your blog or document or whatnot!

Writing schemas to check the validity of the schemas that we use to validate our YAML is the most computer scientist I've felt in a while.

It works, too - the validation schema validation truly helps me not make errors when writing validation schemas

scheidegger,
@scheidegger@mastodon.social avatar

We also use it to derive TypeScript typings from our validation schemas, which is a very simple thing to do, but really nice.

https://github.com/quarto-dev/quarto-cli/blob/feature/emit-json-schema/src/resources/types/schema-types.ts

And so we can also have typescript types for our schemas, so our typescript code for schema validation can be well-typed as well https://github.com/quarto-dev/quarto-cli/blob/feature/emit-json-schema/src/resources/types/schema-schema-types.ts

Fun typo in this quote from a Hollywood Reporter story about Netflix's 3 Body Problem: “Liu Cixin’s created this inedible trilogy and the books just get better for me." Completely changes the metaphor, and meaning. https://www.hollywoodreporter.com/tv/tv-features/3-body-problem-season-2-netflix-1235857474/
