Fed into a clear Claude Code max effort session with : "Inspect waldo2.png, and give me the pixel location of a raccoon holding a ham radio.". It sliced the image into small sections and gave:

"Found the raccoon holding a ham radio in waldo2.png (3840×2160).

  - Raccoon center: roughly (460, 1680)                                                                                            
  - Ham radio (walkie-talkie) center: roughly (505, 1650) — antenna tip around (510, 1585)                                         
  - Bounding box (raccoon + radio): approx x: 370–540, y: 1550–1780                                                                
                                                                                                                                   
  It's in the lower-left area of the image, just right of the red-and-white striped souvenir umbrella, wearing a green vest. "

Which is correct!

Any reason BetaFlight doesn't appear to have even basic pre-shared key symmetric encryption? Some ciphers aren't that CPU intensive.

Do any of these attacks matter for single-tenant computers where all network packets are sent on a hardware timer (say, 10 kHz) independent of crypto computing? Doesn't that mitigate any side-channel timing attacks from the start?

Show HN: ChaCha20nosat, a symmetric cipher that resists being put into SAT form

makira — Mon, 25 Sep 2023 13:39:09 +0000

There has been a recent discussion about the monoculture in crypto, and how ChaCha20 is a fallback to AES256.

All current mainstream ciphers are relatively easy to transform into SAT form. This is a proposal for a fallback for that, using polymorphic constraints between the bits via sboxes that are part of the private key.

Suggested changes to avoid redoing XChaCha20: since the sboxes could be the entire private key, what was the key could be a 256 bits nonce, and what was the nonce could be the counter, and what was the counter could be a stream index: such a modification could be called yadacha20.

Small, self-contained super ugly, quickly written Rust code: this is an initial draft of a work in progress. The goal of this post is to get feedback as early as possible.

Thank you.

Thanks Ivan, makes sense. With the ongoing work of integrating Rust into Linux, I hope we'll see some of that sought-after stability in its tooling. I appreciate the insight - I also wish more code was written with long term in mind, and by long term, I mean decades, not years.

What's the status of Rust usage inside NASA? I am currently writing software that, hopefully, will be sent to the Moon one day, and I am considering options as to software technologies.

New comment by makira in "The Man Who Was Allergic to Radio Waves"

"A review published last year in the journal Bioelectromagnetics found no evidence that hypersensitive individuals had an improved ability to detect EMFs, and the study found evidence of the nocebo effect in those same people."

Every time I see someone claiming to have extremely clear symptoms of EMFs sensitivy, I wonder why they don't do a double-blind test to prove the whole world they can actually detect radio-waves. Should be a trivial test to perform properly, and would clearly help the case of hypersensitive people, so why hasn't it happened yet?
