lucisferre··on Claude is a Contrarian
I wonder if it is more of a fixation problem. In that by asking it not to do something you increase the likelihood of it doing that thing because the words for the thing are there.

Sort of like how sometimes drivers fixate on a thing they are trying not to hit and as a result run right into it.

lucisferre··on Claudette: Make Claude stop talking like a BuzzFeed article
Evidence or not, this is probably the most satisfying explanation I've heard for this behaviour.

My own suspicion is that LLMs are not becoming more general-purpose over time, as these companies had hoped, and ongoing development in that direction is stalling. They will likely need to move in the direction of more specialization and train LLMs for specific use-cases. However, this would also be admitting that they are not on a direct path to AGI.

lucisferre··on Rails Is Built for AI
AI needs typing? Why? That seems counterintuitive to me.

I agree on ORMs, but that would apply with or without AI for me personally. ORMs and ActiveRecord are an obvious and well documented anti-pattern at this point in time.

lucisferre··on Grok 4.6
I think it is fair to argue that prompts are not a safety layer at all and can't be relied upon for much.

"Make no mistakes"

lucisferre··on Is AI reasoning right for the wrong reasons?
I wonder if some of this explains why people have been finding with Opus 5 that running it with lower settings than "High" is producing better or at least just as good results.

> Not so fast. A 2025 paper(opens a new tab) from Northeastern University and the University of California, Berkeley on frontier open-source LRMs showed that between 30% and 60% of their “thinking steps” had “minimal causal impact” on the answers the models produced to benchmark math questions. Chop half of them out, and a model’s performance barely suffers. “We want to be careful when we review these chain-of-thought prompts because they may not be linked to the final output,” said Weiyan Shi(opens a new tab), one of the study’s authors

lucisferre··on Why I Stopped Arguing with People
This comment is so brutally ironic. Wow.

You are technically correct. The best kind of correct.

This is the critical problem with all of this.

Daylight savings time changes, can't be globally banned fast enough really.

Darling, we'll always have W_q, W_k, W_v, and W_o.
lucisferre··on Amazon Has Axed Its New Stargate Series
Given the IP situation, is shopping it around even on the table?
lucisferre··on LLMs are not the black box you were promised
They are mostly "faster" than the majority of humans. They are rarely better than experienced and talented humans at the majority of tasks they are able to do. They are better on both scales on a small thin slice of work tasks.
lucisferre··on Starship V3
I dunno I was listening to someone explain this on a podcast and to put up something on the scale of a typical land based data center would make it, by orders of magnitude, the largest spaced based object ever made and most of the size would be the radiators.
lucisferre··on Removing the modem and GPS from my 2024 RAV4 hybrid
I have the same car and want to do this, but not for the reasons the author noted but because the GPS unit in the car is broken when paired with Carplay and has the wrong compass heading causing navigation to be completely useless.

I have reported this to Toyota multiple times with videos detailing the problem and they have denied the problem and ultimately when faced with the evidence simply refused to fix it.

I've been a big fan of Toyota's Production System and their management culture, but this experience has really diminished the brand for me. I realize these problems exist with all cars today. The pattern seems to be to foist low-quality hardware and software on their customers and take no responsibility for the results. Software bugs aren't what they consider a "typical car problem" so they simply don't fix them.

lucisferre··on OpenAI puts Stargate UK on ice, blames energy costs and red tape
Man I thought this was about the new Stargate show which they are filming in the UK. I was trying to square why OpenAI would be in charge of that.
lucisferre··on Apple randomly closes bug reports unless you "verify" the bug remains unfixed
It's open source software. If you discover the bug, have written a failing test that demonstrates it, and a proposed solution to it, then maybe you can be annoyed when the authors close it as wontfix.

Otherwise OSS is pretty much as-is, where-is, with the exception of very widely used and corporately supported projects.

lucisferre··on Tiny electric motor can produce more than 1,000 horsepower
I would expect that lighter motor components would potentially allow weight reduction in load bearing components. Not an advantage for SUV-type cars, but for light and ultralight vehicles it could add up to more weight saving and longer ranges.
lucisferre··on The AI emperor has no clothes
Does NFT/blockchain actually have a cycle? I have not seen any real killer use cases.

AI may be overhyped but the actual use cases and potential ones seem very clear.

Fair comment.

lucisferre··on Does OLAP Need an ORM
I agree with this as well. I started my career at the height of ORMs. Most software developers were only learning the ORM APIs (which of course all differed significantly) and very few were learning SQL outside of the bare basics.

ORMs, like all abstractions, are a leaky abstraction. But I would argue because of the ubiquity and utility of SQL itself they are a very leaky one where eventually you are going to need to work around them.

After switching to just using SQL in all situations I found my life got a lot simpler. Performance also improved as most ORMs (Rails in particular) are not very well implemented from a performance standpoint, even for very simple use cases.

I can not recommend enough that people skip the ORM entirely.

lucisferre··on AI is different
Realistically most people became aware of the internet in the late 90s. Its impact was significantly realized not much more than a decade later.
lucisferre··on Fast
So not PowerBI then. Or really any BI tool.

My favourite example of not "fast" right now is any kind of Salesforce report. Not only are they slow but you can't make any changes to the criteria more often than once a minute. Massively changes your behaviour.

lucisferre··on GPT-5-reasoning alpha found in the wild
Seems a bit early to use that analogy though. Early iPhones upgrades generally had significant improvements in almost all specs.

lucisferre··on AGI is not multimodal
Much of the discussion of AI flirts with science fiction more than fact.

Let's start with the fact that AGI is not a well defined or agreed upon term of reference.

lucisferre··on Chomsky on what ChatGPT is good for (2023)
"The desert ants in my backyard have minuscule brains, but far exceed human navigational capacities, in principle, not just performance. There is no Great Chain of Being with humans at the top."

This quote brought to mind the very different technological development path of the spider species in Adrian Tchaikovsky's Children of Time. They used pheromones to 'program' a race of ants to do computation.

Wow, that's not confusing at all.
