  • I just tried “Language Drops” and it was… interesting. It didn’t place me at the right level, so I got a very beginner lesson when I’m closer to intermediate (but definitely not fluent). I’m not sure I liked matching the pictures- the picture for “thank you” could mean different things depending on how you interpret the person’s face and body language- and then I hit the end of the free content for the day. It didn’t get to different tenses or even whole sentences- just basic vocabulary and no verbs. Maybe it ramps up quickly?


  • I hate space yielded to cars that would be better used some other way.

    All those cars parked on the side of the road? Could be a bike lane. Could be outdoor seating for the restaurant. Could be benches. Fuck those cars.

    Big ass parking lot? Could be something green. Could be another building. Fuck those cars.

    i don’t think we should promote private car ownership. If someone needs point to point transit occasionally, we can solve that some other way. I know people that have a car because they go on trips a couple times a year. Wasteful.

    If people want a car of their own, they should pay all the externalized costs.









  • Oh yeah. Cars are bad on like every metric.

    Socially they isolate people. You don’t interact with anyone when you’re driving except to get angry. The micro interactions you have on the train matter. Seeing people that aren’t just like you, also annoyed that the train is delayed, or just having a nice time with their kids, matters. More than makes up for when other people are annoying.

    Economically they hurt. It’s much harder to just pop into an interesting looking shop when you’re cruising along at 40mph. All the space dedicated to parking could be used for other stuff- housing, commerce, communal space, whatever.

    They make spaces less safe. Other than the direct impact (no pun intended) of people getting hit by cars, or crashing into stuff, a space that has steady foot traffic is generally safer. If everyone was in their car instead, you’d probably be alone on foot with no one to help if something happened.

    They’re bad for the environment. Air pollution, micro plastics, whatever.

    Drunk driving is way more dangerous than drunk “riding the train”.

    The more non-car options are built out, the better it will be for people who need to drive for whatever reason.

    Cars culture is trash and if we ever escape from it, it’s going to take years.






  • This reminds me of the new vector for malware that targets “vibe coders”. LLMs tend to hallucinate libraries that don’t exist. Like, it’ll tell you to add, install, and use jjj_image_proc or whatever. The vibe coder will then get an error like “that library doesn’t exist” and "can’t call jjj_image_proc.process()`.

    But you, a malicious user, could go and create a library named jjj_image_proc and give it a function named process. Vibe coders will then pull down and run your arbitrary code, and that’s kind of game over for them.

    You’d just need to find some commonly hallucinated library names



  • Many people have found that using LLMs for coding is a net negative. You end up with sloppy, vulnerable, code that you don’t understand. I’m not sure if there have been any rigorous studies about it yet, but it seems very plausible. LLMs are prone to hallucinating, so you’re going to get it telling you to import libraries that don’t exist, or use parts of the standard library that don’t exist.

    It also opens up a whole new security threat vector of squatting. If LLMs routinely try to install a library from pypi that doesn’t exist, you can create that library and have it do whatever you want. Vibe coders will then run it, and that’s game over for them.

    So yeah, you could “rigorously check” it but a. all of us are lazy and aren’t going to do that routinely (like, have you used snapshot tests?), b. it’s going to anchor you around whatever it produced, making it harder to think about other approaches, and c. it’s often slower overall than just doing a good job from the start.

    I imagine there are similar problems with analyzing large amounts of text. It doesn’t really understand anything. To verify it’s correct, you would have to read the whole thing yourself anyway.

    There are probably specialized use cases that are good- I’m told AI is useful for like protein folding and cancer detection- but that still has experts (I hope) looking at the results.

    To your point, I think people are trying to use these LLMs for things with definite answers, too. Like if I go to google and type in “largest state in the US” it uses AI. This is not a good use case.
