I really, really wish that CAN had caught on more for sensor networks in the hobbyist community.
It's so much nicer than I2C in so many regards: much longer range, masterless (any node can talk directly to any other node), packet prioritization built-in, deliberately designed to be more or less impossible to wedge, possible to do IC-to-IC on a board without transceivers by using a shared open-drain bus (like I2C, but with only one wire!)... and plenty more.
Really the only downside to CAN is that the spec requires timing that's tight enough that everything has to have a crystal on board. Ah, to have an alternate reality where CAN's timing requirements were relaxed enough for that not to be a requirement and it had caught on as the IC-to-IC interconnect standard instead of I2C...
LIN bus isn't masterless though, if I recall correctly.
That's the nice thing about CAN: every node is equal, and every node can send a message whenever it wants. As far as I know, LIN doesn't do that: you have one node on a given LIN network that initiates all communication, much like I2C, and the most other nodes can do is reply.
It's fine for what it is, of course, it's just missing some things that I think make CAN really neat.
> HuggingFace got hacked by an AI. What stuck out to me was the guardrail asymmetry. The attacker had no constraints, but HF's response ran afoul of the abuse guardrails, forcing them into an unplanned switch to local models.
This, to me, is the more interesting bit of the article.
I don't really know what a good solution looks like, but yeah, that's annoying.
I just had this happen today. It was indeed a segfault.
From what I could tell it looked like it was in JS code that had been JIT compiled. I haven't attempted to troubleshoot further beyond setting all my future Claude Code instances to pipe their stderr to disk so that I don't lose the stack trace next time.
I did talk to a corn/soybean farmer on this recently and they weren’t nearly as concerned as I would have thought. They said they pay JD to maintain their equipment anyway. The equipment is apparently so expensive and sophisticated that people are wrenching on it much themselves (similar to the trend in road vehicles).
I just realized that Netflix’s Reed Hastings is the same Reed
Hastings that wrote Purify - the excellent memory leak tool that was a pretty big deal back in the 90’s.
They didn't say that HN is turning into Reddit, they said that the conversation quality has gone to shit.
I don't agree with that statement universally, but I have to say I do when it comes to this article. I came here hoping for substantive discussion from those who'd had a chance to try it out; instead what I got was a seemingly endless stream of venting. There's a place for venting - and plenty to vent about with the state of AI nowadays - but to borrow from the HN guidelines you linked, it does very little to gratify my personal intellectual curiosity.
When they release new versions of Sonnet, no-one expects them to be better than Opus.
