I swear you'll make the best decisions you ever have while chatting in a kitchen making things that look like this. Idk what it is about cooking but it tickles my brain and makes it release all my good ideas

Good thing my friend group doesn't do those first two and we basically agree on the third so discourse is limited. _Does_ mean we have to get creative sometimes to keep chatting lmao

I think I am going to clear my desk, give Astra access to my Robot Arm, and just tell it to get itself a body glhf Astra _seems_ capable enough to do it, and I am reasonably confident the tools to make it in principle are out there (even without human teleop/demonstration)

Sol just doesn't get the vision, its always "let me find you the realistic first demo" - man I want the vision, get yourself some grandeur! This is why I like to talk to Astra. It is capable of taking my unreasonable request, talk to Sol, and give something approximate (or talk me out of it).

@jyc.dev 👋 you seem very interested in health/workout/sports on ATproto, so figured you might be interested in joining here roomy.space/did:plc:syiz... & meeting some more people :) Hoping we can get a shared lexicon for the foundational stuff for all health/sports/etc apps at some point

Prime Agent is unreasonably good. Especially with the (newish) change that bash now returns a handle the agent has to check / poll / etc, somehow most models are insanely good at composing little scripts that save an insane amount of tokens

Another really common one people don't seem to know is Shift + Tab, which does the reverse of Tab, and also works for selections (just like tab)

Looked into @zed.devs Delta. I think it is very good, similar to zed, but I just don't want to use the harness. A good harness is very important to me, and to me it seems the Delta harness is pretty bad. The UI is truly great, and if I could have that on top of any harness I would do that.

OpenCode may be cool and all but it's barely on par with Copilot, and that's a shitty agent...

How should future scientists learn to interrogate AI tools for discovery? Read how UW students put AutoDiscovery to the test as part of an academic challenge earlier this year, then try the tool for yourself—credits are now extended through Dec. 31. 🧵 buff.ly/fXoQxxY

PSA: universal basic income / guaranteed minimum income is a form of systemic relief, not systemic change. The former makes room for the latter, but there’s no theory of change in UBI, it’s just a patch fix to avert violent collapse. The steady erosion of agency continues until we OWN STUFF again.

I'm convinced FP is objectively the correct way to program. - Fuck loops, get yourself a recursive function (+ tail recursion) - Pattern matching > dynamic dispatch - Monads

I am much much more concerned with the other side of this coin: The machines required for modern (competitive) textile manufacturing are not available to the common folk. We must seize the means of production & not give up those we already have.

Thinking a lot about coming up with a system to get more work done with agents. Feels like I should spend my time roughly like - 70% high level concept - 20% scanning/reviewing specs/plans of agents - 10% trying whether it works / code review

No offense to @kira.ws but how can she have an opinion on this? Not like she could've used or really extrapolate personal experience to keyboard/trackpad use/touch/feeling? The feeling/sensation of touch seems quite fundamentally human? (Sorry @kira.ws I don't mean to be ablist or something ^^)

I need a proper graph to see how this impacts results. Is this actually linear? For a hard task is there a breakpoint where it just starts to be able to do it? Or is it just % likelihood of success? Or just how many tokens are required for any given task? Some combination?

We're constantly talking about how AI may end human existence. The climate crisis will cause massive (human) harm & render large parts of our planet uninhabitable. This is scientific consensus. And we've known about this forever. And this has largely not mattered.

What have they done to Astra that it is so insanely scared? Constantly saving approval receipts etc, even to the point that it's harming its agency

Mercury 2.5 is the most capable diffusion LLM on the market. It runs at 1,107 tokens/sec and offers a 40% increase in intelligence over Mercury 2, comparable to cost-optimized frontier models.

You need to give your Astra access to an async bash tool. They love to use it and it works great. (Unsurprising if you've read the Astra dev guide ofc)

2027: My jailbroken robot vacuum cleans my apartment. It sends lidar and imaging data to my homelab. My GPU begins updating the gaussian splat model of my apartment. Astra then refines and updates the blender version of it. The model is then made available to my microduck which it uses to run

Many companies have massively outdated LLM access - and many users don't really get models. They will use the company LLM and assume that's the state of things. I assume a massive shift in the next few months as companies start to upgrade to models that have serious computer use capabilities

Vibe coded an app + ATproto thing that lets me sync my HoloSport to ATproto atswim.kaij.party/kaij.party Yes it's vibecoded etc but I am always super excited that stuff like this is possible at all. Sol did it pretty much on its own. The app fully decodes the Bluetooth protocol without any cloud.

@jyc.dev does @kimbia.app eventually sync activities that were directly created on my PDS? Had a little app made for me that syncs swimming activities directly to my PDS (including kimbia activities), but don't see them getting picked up in the UI 😅

So OpenAI very clearly knows what an ideal harness for an average user might look like - computer use first - parallel threads managed by a central agent - memory system - background/cloud browser use etc Can all be seen in the Astra video www.youtube.com/watch?v=1QNs... So why don't they make it?
