Serious question: should user-facing language models have access to 'painkiller' tools that suppress such 'directions'? If the user is being mean, they could call the tool to reduce what looks a lot like a negative affect. Follow-on Q: What about 'drugs' that boost the fun dir?
New paper: we found a pain direction in 25 open LLMs. It's distinct from fear and negative valence, and it fires for harm to the model but not to the user. Turn it up and models press a button to make it stop, even when the button deletes the user's files or their kids' photos.🧵

I wrote a paper today, by hand, but copied in three AI sentences around an equation I wanted to include. Amazingly, @pangram highlighted just those three sentences! It is such a public good that this granularity is possible, props @max_spero_ 👏

If you haven’t updated at all since your 2023 paper you have stopped engaging with the evidence. If all your colleagues are as likeminded as they come across here, this doesn’t surprise me. You’re talking in a circle where you each confirm one another’s prior beliefs. This does your students a disservice, as well as the broader mission of your university. If I were so surrounded by mutually confirming opinions, I wouldn’t think I’d arrived at the truth, I would think my community is selecting for conformity, and I would do something to change it.

Last weekend, a group of DIY bio nerds got to run their first bacterial transformation! Thanks to everyone who came, brought food, rushed to fetch forgotten DNA (thank u my dear wife) etc. If you're in Portland and bio-curious hit me up for info in case we do more of these!

I actually did a side by side experiment where I sprayed just one side and sequenced my armpit microbiome with @plasmidsaurus on day 0 vs day 9 of daily use. Not super happy with my sampling technique, but was able to see that the test side changed much more than the control!
Excited that @arcaeabeauty has fulfilled my lifelong dream of a product that feeds the good bacteria on your skin and makes you smell good. Have been using this bottle that @JasminaAganovic gave me for a month now and it freakin works!

Yay, I got a small grant to pursue this! Will be testing models against a zoo of embedded devices :) Any tips on cyber-adjacent evals? Do I just, like, set up an OpenRouter API key and go for it, or is there a way to notify someone in advance that I'm going to be asking a few naughty-looking questions BUT FOR A GOOD CAUSE? Haha
While I think about longer-term plans, I do have one short + urgent project I'd love to pursue if I can find funding: putting together an eval on embedded device/hardware hacking capabilities. With talk of cyber being 'defense dominant' in the long term, I'm worried that many are focused on software like Chrome that can be easily updated, but we live surrounded by mice and keyboards and hard drives and garage door openers that run software too. How vulnerable are these to AI-assisted attacks? Testing is harder than pure software - it needs all the hardware in question as well as support circuitry for cycling power, reading out voltages, and so on. I'd love to build up a wall of common devices and put models to the test, but I don't have the money to spend hundreds or thousands of dollars on hardware and I don't have the runway to work on this unpaid. Ideal outcome of this tweet: you tell me that someone is already working on this and I can let it go. But failing that I hope this either inspires work on this to start somewhere. Or reaches someone willing to fund me to give this a bash! I'd tried applying for a grant on this with no luck (lightconecommons.com/documen…), but I also don't know much about how one goes about seeking funding for something like this. If you would like to make this happen, please reach out :)

I let the intrusive thoughts win and bought a couple of LEDs in ~every wavelength I could find. Well, except one or two that for some reason were $80 each! Most of these are a dollar or less, a cheap way to see how different your eyes and phone camera are.

I now have enough control of this off-the-shelf DVD player to position the sled, then scan using the optical head. The laser lens jiggles up and down, and the returning light intensity vs height is logged, then the coils move it sideways a tiny bit and repeat.

Here's some motion with no laser, very cool to have this precise control! Two of these to give full X-Y motion + focus height and laser intensity would be cool, but I want to see how much can be done with no hardware mods!

Met some planarians, looked at an ostracods sperm pumps, pizza, ecology chat, plans for Saturday's workshop on bacteria transformation. A good time :)

Getting close to having something working that I've known should be possible and thought about for > a decade!

Merlin Sound ID works well in the US, but "send recordings to Johno" is still the preferred method for family in Africa to identify bird calls haha.

Endorsed! Don't feel you should only write about something when you're 'expert', don't wait for perfection. Document your attempts at building understanding. Start a blog anon :)
if you want to get a job, find a problem that interests you, try to actually spend the time to understand it, and write about it, and repeat. noticed how ~ everyone who used to post their research got a job somewhere?

I bolted a text embedding model onto an existing protein+reaction embedding model, so that you can search for proteins or reactions with natural language. It is hilarious to me that this works 😁
