I'm unreasonably fascinated by, delighted by, and excited about #compsci #education #cycling #cricket and the general human experience.

See https://mastodon.social/@shriramk/109302532598801863 for longer #intro.

Having agents make phone calls to (eg) restaurants a loss. It exposes a lack of an API. Restos will be overwhelmed and buy agents to handle the calls. Two giant software stacks will churn taking OOM more time and energy to imprecisely do what an API call could have nailed. ↵

@craigbro@infosec.exchange But restaurants already expose "APIs" in the form of reservation websites. And I LIKE being able to use my computer to make an unambiguous reservation, auto-added to calendar, any hour of day or night, sometimes in countries where I barely speak the language and a phone call would be very difficult. (Using AI to live-translate that call would be far worse in every way.) Did that 3 times this summer. An agent making one call isn't spam. *All* of us each using agents ~becomes a DDOS.

@pnutzh4x0r@social.ndlug.org FYI: "the author of that piece" is actually the Editor-in-Chief of CACM, our flagship publication, and a very distinguished researcher himself. I.e., absolutely not a nobody, and very much a "peak somebody". If a person with his background feels ACM is just a publishing house, not a society of professionals, that's really telling. @ACM@mastodon.acm.org

That ridiculous feeling when you put on a dumb Hindi comedy/action movie (Bank Chor, 2017) to chill, and half-way through are startled to find that one of your best friends from high school, Suresh Venkat, is in it. Totally destroyed my concentration, which fortunately it did not need.

@Nead@social.vivaldi.net @olynch@mathstodon.xyz Sorry, what's the theory here? They replied saying "no, I wrote it by hand, spending an hour on it" and had an LLM generate everything else (or perhaps even that)? What would be the point? (They did say they consider LLMs to be partners in their work — but explicitly not for the emails.)

One of the fun things about being yelled at and 'splained about GenAI coding by various people on here is that multiple people who live in Providence (one whom I didn't know earlier) reached out through DM and said, "hey, wanna talk about AI?", and I've had fun meeting each of them in person. Thanks, Mastodon!

I would really like passkey advocates to lay out in full how one helps elderly parents once they switch to passkeys. (Can be done; not trivial. This article rambles about YubiKeys—like typical customers need one—while entirely missing this disadvantage.)

One of my favorite uses of Claude is to show photos of things from airplanes and ask it to teach me more about geography/geology. Sometimes it needs help with geolocation; then it'll even go dredge up research articles about the area. Like the various "geology from planes" books.

Man, old universities are weird places. Went to attend a talk (featuring linguists and computer scientists debating language models) in a room I hadn't been in before, and it turns out they have a full-ass Flemish tapestry just hanging from the wall.

RE: https://discuss.systems/@keithpjolley/116488992855908604

It's not just "code", it's also algorithms, libraries, solvers, etc. I see this problem all the time with Claude Code, and indeed this was a central theme of our agentic coding class.

discuss.systems

keith (@keithpjolley@discuss.systems)

code reuse is what separates the seniors from the juniors. any chump can go out and create code completely unawares that others have already figured out how to deal with all the corner cases you have silently dismissed or not thought of yet. it takes a pro to say "fuck that, i don't want this software to be the monkey on my back for the next N years."

I've been waiting for articles that point out the existential threat that AI coding technologies pose to the Indian tech sector. Here's one. I fear that the social and cultural—and hence political—consequences in India could be even worse than in the US.

The restoration of the Ghent Altarpiece is *absolutely stunning*. There are lots of videos of the restoration work, so I wanted to see it afresh. The 30 min AR tour is actually not half bad either (& you can skip ~10min if you know all the history). Brilliantly exhibited too.

@jack @Alon In Balatonfüred, a town by lake Balaton, there's a lovely grove of trees, each planted by/in memory of the "Martians". Of course labeled by their Hungarian names ("WIGNER Jenő", etc.). I assume there are many more memorials to them now, but this one really stood out in my memory from back then.

But I am also redesigning my PL course for the fall and got a lot of useful feedback about my planned design. For any other kind of redesign of my course I would be able to get a useful online discussion (even if I disagreed with a lot of it!), but on this one [what is the impact of agentic coding]…not a chance!

@tealeg Haha, that's funny! In fact the Wikipedia label says "Paul Erdős at a student seminar in Budapest (fall 1992)", which was a year later. I can see why it would be the same background, and I think he tended to wear the same clothes. I do have well-focused photos of him, at least as good as the Wikipedia one, but with other people in the frame who would be hard to crop out…

I'm corresponding with a person where I'm certain the writing is AI; they say absolutely not, they spent an hour on it; but the rest of the reply has the same smell. They seem to really want me to respond, so I presume they're telling the truth. Have people ALREADY lost writing?

Something I love about film festivals is, whereas most commercial movies are made for audiences & fine-tuned by algos, here you still find self-indulgent flicks. Some are terrible, and some are just amazing. RIIFF is one of my favorite things about summer! https://film-festival.org/
