What can a neuron compute?
Real biological neurons are complex, but how capable are they?
Using a new method, we found that a single cortical neuron can classify cats vs dogs, recognize spoken words, and solve 10-bit parity, all tasks thought to require entire networks. (1/15)
I spent 48 hours with the Kimi K3 modeling code.
It took:
- 650 mg of caffeine (mandatory)
- 40 cans of LaCroix (optional... world record (?))
- 8 papers
- 6 months off my lifespan
Finally grokked the entire lineage of Kimi K3 and how we got here... every single step, since 2019 GPT-2
CLAUDE HAS A SERIOUS PRIVACY PROBLEM RIGHT NOW, A HUGE NUMBER OF SHARED CONVERSATIONS ARE PUBLICLY INDEXED ON GOOGLE FOR ANYONE TO FIND
when you use claude's share feature it makes a public link. it turns out those links got indexed by search engines, so "share with anyone who has the link" actually became "anyone can find this by searching"
and people are pulling up genuinely alarming stuff:
> api keys, credentials and crypto wallets
> personal resumes with real names, addresses and phone numbers
> a lawyer working through a potential ethics violation
> an engineers internal company project details
> what appear to be peoples social security numbers
> and a crazy number of deeply personal chats people never imagined another human would read
anthropic never added a noindex tag to those shared pages, so search engines were free to crawl and list them
one line of code would have prevented the whole thing
this already happened to chatgpt about a year ago, same exact issue, but openai patched it fast
if you have EVER hit share on a claude chat, assume it could be public
go to settings > privacy > your data > shared chats > manage
delete anything you dont want the whole internet to see, especially anything personal or financial
