nixpulvis··on Pi 1.0
Doesn't pi just have 4 tools?

- read - write - edit - bash

nixpulvis··on Pi 1.0
I found this: https://arena.ai/blog/coding-agents-harness-tax

Seems to support my skepticism.

nixpulvis··on Pi 1.0
What is the harness doing that's not the model.

I've been assuming a harness is basically a set of tools and a TUI for passing text to the model and the model coming back with tool calls and user responses.

Are the tools really that complex and different between harnesses?

nixpulvis··on Pi 1.0
A coworker was trying to tell me that models perform better in their own agent harnesses. I use both `pi` and `omp` and I'm somewhat skeptical. I understand that the tool calls might be slightly different. But really how much impact on the model itself does the harness have?
nixpulvis··on Git 3.0's upcoming SHA-256 default will be a costly mistake
I'm going to completely ignore the first part of this post because I'm not interested in arguing about how severe the issues with SHA-1 are. I think it's accepted that there are flaws.

So given that, I'm more interested in the arguments for why migrating to SHA-256 is problematic.

The biggest issue I see, after skimming over it, is the submodule breakage for new projects trying to link to old projects. This seems solvable frankly, but is the only serious issue I see. Everything else will be worked out as software is updated IMO.

nixpulvis··on XCancel service is suspended until further notice
I think LLMs providers pretty directly compete with content they scrape like Wikipedia and SO...
nixpulvis··on Stabilizing Rust's Never Type
A reference to a value isn't the same as the value itself. I'm confused the point you're making here.

You could keep using the old compiler, no?
nixpulvis··on Claude is only available to people over 18 years
I firmly believe that tech companies being responsible for parenting our children is a deeply misguided response to a failing society and overworked parenting generations.

I benefitted greatly from early access to computers and the full scale of their capabilities. It was a constant issue in my family limiting screen time, and who knows what the exact rules should be for everyone. For me it was a dynamic ruleset I was actively involved in the development of.

I could make compelling arguments to my Mom, that will not be the case with Meta, or Apple, or Anthropic.

Accepting "OS level" age validation is surrendering to a system meant to protect the industry, not our kids future. And while there are serious conversations we should be having about how to control technology use, it should be about parental controls and sane defaults, not age validations and legally restricted access by providers.

I hate how even the most progressive-minded people on most fronts are falling into this trap because big tech has failed them and they are angry at it all.

nixpulvis··on Debian votes to allow "responsible use of generative AI"
Yea, that's sorta my point. We're not, or at least I'm not to the point I have a local model as good as Opus yet though.
nixpulvis··on Debian votes to allow "responsible use of generative AI"
It's not even that I'm slower at manual coding anymore, though I very well could be, it's that my expectation of my own progress has shifted. I'll be frustrated to only get a fraction of what I could have done.
nixpulvis··on Debian votes to allow "responsible use of generative AI"
Big difference though, once you know how to read and write, nobody can take that away from you.
nixpulvis··on Debian votes to allow "responsible use of generative AI"
The issue with AI is not its obvious value, it's our dependence on it. I worry what will happen to me when I am cut off for some reason.

Local models are going to be really important and hopefully computing costs don't make it too prohibitive.

nixpulvis··on We found a division by zero bug in FFmpeg with a vibecoded fuzzer
I can't speak to the quality of the fuzzer since I haven't used it or looked at it thoroughly, but it does seem to cover a lot of ground on features and interesting concepts. I'll definitely be reading more into what you have here.
nixpulvis··on Pass the Passkey: A Novel Attack Surface in Passwordless Authentication
I'm not against physical keys at all. I have one on my keychain. I'm against making things hard to maintain ourselves. Being dependent on Apple and Google to agree before we can own our own keys is what bothers me.
nixpulvis··on Pass the Passkey: A Novel Attack Surface in Passwordless Authentication
Why is a password manager a "service" it should really just be a program and as many encrypted backups as you want. Maybe you pay for them to host those backups, but that's a choice you should be able to make.
nixpulvis··on Pass the Passkey: A Novel Attack Surface in Passwordless Authentication
How is this easier than just using a password manager? Why not standardize the password input mechanism so they reliably update, etc.

I feel like all of the security of passkeys could have been build in a compatible way with new standards and enhancements to existing password interactions.

nixpulvis··on Pass the Passkey: A Novel Attack Surface in Passwordless Authentication
Bug tech isn't a single entity. But I strongly believe a different group would have finished this obvious gap by now.
nixpulvis··on Pass the Passkey: A Novel Attack Surface in Passwordless Authentication
It's ao comically bad it proves the while thing is a joke unless you're trusting Apple or Google to sync and back them up for you. One cynical angle at why the backup is being slow-rolled is because the major players have an incentive to not do it. They want you dependent on them and locked into their ecosystem.

It's completely insane to treat a credential to an account as something that cannot be backed up. It implies there's another form of recovery, which likely means that key is only as secure as the other recovery options. And when it comes all the way back to the master key to your manager itself the loop falls somewhat apart.

It's a hard problem, but passkeys aren't ready for me yet.

nixpulvis··on Pass the Passkey: A Novel Attack Surface in Passwordless Authentication
It's not functionally equivalent, but it is a workaround, but requires doing it on every site (if they allow it) and it cannot be freely moved and re-backed up offline from the site.

The actual reason is people have many devices. I assume this is at least somewhat common, but I still avoid passkeys so IDK.

You're designing a system where we should just be able to backup our own keys if we want to.

nixpulvis··on Pass the Passkey: A Novel Attack Surface in Passwordless Authentication
Have we standardized a way to backup and export passkeys yet? Do websites commonly allow multiple passkeys to be registered?
nixpulvis··on Git rebase -i is not that scary
I feel like if you're scared of rebasing, you don't actually understand git.

Not using big_space :(
nixpulvis··on Interview with Mitchell Hashimoto about Ghostty and Zig
It doesn't and I never said anything about preferences directly. There are however culture wars, and they cause problems throughout the industry and discipline.
nixpulvis··on Interview with Mitchell Hashimoto about Ghostty and Zig
Culture wars are sadly one of the biggest inhibitors of progress throughout all of technology.
nixpulvis··on Every new car sold in the European Union must include a driver monitoring camera
If they make cars irritating enough, people might give up the joy of driving and pivot to more economical transit modes. I have mixed feelings about this, and I doubt the car companies are thoughtfully doing this, but I do wonder sometimes.
nixpulvis··on Free the Icons
I was originally excited by the flat design revolution because it appealed to my affinity with uniformity and consistency. But I believe now that I was ignorant and lazy. Bad design still exists within flat style rules, and it has an even worse and cheap feel to it. Meanwhile we've lost whole dimensions of expression.
nixpulvis··on Companies rein in AI usage as costs strain budgets
If a thinking machine can find new mathematical proofs we haven't thought of yet, it might also find new medicines and other things that really do make it worth finding a way to live with. If I can ask the thinking machine to find bugs in my code and it does, that seems nice to have.

The analysis that I want is on a studied cost/value basis somehow. I'd start by trying to force tech companies to sell products at cost sooner, so it's not driving markets before it can truly be absorbed. I'd also ask for energy/resource consumers to be forced to buy climate credits which are used to help offset the impacts and fund research and development for sustainable technology.

nixpulvis··on Companies rein in AI usage as costs strain budgets
Google was never immune to spitting out junk BTW.

Like I said, if you can't see the value in AI, I'd hedge a bet you haven't tried. Even a brief conversation with google's can help identify a gap in your understanding of many topics.

How we balance the positives with the negatives is the hard part I want to hear thoughtful and studied opinions on.

nixpulvis··on Companies rein in AI usage as costs strain budgets
I think it's worth understanding the technology so we can have informed strategies for how to best regulate it.

We don't solve the climate crisis by abandoning all the technological progress which has put such a strain on our ecosystem, we solve it by rethinking how we use this technology, and finding new technologies and policies to better meet our needs.
