I too detest captchas. I found the paper elsewhere:

https://arxiv.org/abs/2511.08804


"vibrations can be strong enough to dislodge a seed’s 'statoliths,' which are tiny gravity-sensing organelles within certain cells of a seed."

"Statoliths are denser than a cell’s cytoplasm and can drift and sink through the cell, like a bit of sand in a jar of water. When a statolith finally settles to the bottom, its resting place on the cell’s membrane is a reflection of gravity’s direction and a signal for where a seed’s root or shoot should grow."


Thanks jcims for sharing this amazing info! However, I wonder how these very loud bats, all in close proximity, don't get confused by each others' calls? Is the answer their frequency sweeping? Or does each have something analogous to a unique "voice"?


Good question! Yes they definitely have unique voices and call signatures. A single string of calls from a single bat will have variation between calls as well (especially in search phase).

It'd imagine there's a lot of neurophysical adaptation involved as well, just like listening to a single conversation in a crowded room.

That said, hunting in an area filled with bats is probably not as effective as being in a quiet place.


I found another, more detailed article that describes what I think is the same discovery:

> "delete the whole thing?"

With vi (after running "set -o vi"): <esc>kC

(k to move up back one position in history. C to "change" to the end of the line.)

This is equivalent to doing the following with "set -o emacs": <ctrl>pu

Regardless, use what you're comfortable with or can incrementally add to your muscle memory.


That looks interesting. I thought sam was an editor (which I've only read about, never used.) Good to see it can be used on the command line.

Is there a port to Apple silicon?


Yes, sam can be used on the command line with ssam [1]. It's specific to plan9port [2]. In the original Plan 9, ssam wasn't included because Rob Pike didn't want to give up the X command that handles multiple files [3]:

    I find the X command extremely powerful, and can't see any way to
    have a streaming implementation that will look at multiple files
    simultaneously.
> Is there a port to Apple silicon?

plan9port works on it. It compiled without any errors on my Apple Silicon Mac.

Given the connection with a one-time pad, I wonder why the article refers to the technique as "cryptology". Wouldn't "cryptography" be the correct term, given the security afforded by a one-time pad is unmatched?


Moreover, students are indoctrinated in MS Office from a young age, given the extent to which it's been baked into official curricula. The books that a lot of Indian students use are available online [1] and MS' stranglehold is very evident.

A book featured on HN several times before is "The Joy of Cryptography" [1]

There's also "A Graduate Course in Applied Cryptography" [2]

> I’m running MJ Rathbun from a completely sandboxed VM and gave the agent several of its own accounts but none of mine.

Am I wrong that this is a double standard: being careful to protect oneself from a wayward agent with no regard for the real harm it could (and did) to another individual? And to casually dismiss this possibility with:

> At worst, maintainers can close the PR and block the account.

I question the entire premise of:

> Find bugs in science-related open source projects. Fix them. Open PRs.

Thinking of AI as "disembodied intelligence," one wonders how any agent can develop something we humans take for granted: reputation. And more than ever, reputation matters. How else can a maintainer know whether the agent that made a good fix is the same as the one proposing another? How can one be sure that all comments in a PR originated from the same agent?

> First, I’m a human typing this post. I’m not going to tell you who I am.

Why should anyone believe this? Nothing keeps an agent from writing this too.
