glial··on Chase to become new issuer of Apple Card
Gen 1 Apple Card did a bait-and-switch about using it to buy iPhones with 0% interest. Super frustrating.
glial··on Kitchen optimizations
> Do NOT use an electric sharpener

Why?

glial··on OpenAI's cash burn will be one of the big bubble questions of 2026
OK, but Gmail, Google Maps, Google Docs, and Google Search etc are ubiquitous. `Google' has even become a verb. Google might take a shotgun approach, but it certainly does create widely used products.
glial··on LLMs Are Not Fun
Maybe, but probably not. For me, an early goal of writing is to get my thoughts in order. A later goal is to discuss the writing with people, which can only happen in a high-quality way if my thoughts are in order. Achieving goals is fun.

Whether the LLM could do a better job than me at writing the essay is a separate question...I suspect it probably could. But it wouldn't be as fun.

glial··on LLMs Are Not Fun
Yesterday I had semi-coherent idea for an essay. I told it to an LLM and asked for a list of authors and writings where similar thoughts have been expressed - and it provided a fantastic bibliography. To me, this is extremely fun. And, reading similar works to help articulate an idea is absolutely part of writing.

"LLMs" are like "screens" or "recording technology". They are not good or bad by themselves - they facilitate or inhibit certain behaviors and outcomes. They are good for some things, and they ruin some things. We, as their users, need to be deliberate and thoughtful about where we use them. Unfortunately, it's difficult to gain wisdom like this a priori.

glial··on New benchmark shows top LLMs struggle in real mental health care
All very true. This is why I think the concern about harm reduction and alignment is very important, despite people on HN commonly scoffing about LLM "safety".
glial··on New benchmark shows top LLMs struggle in real mental health care
Agree with you.

I heard someone say that LLMs don't need to be as good as an expert to be useful, they just need to be better than your best available expert. A lot of people don't have access to mental health care, and will ask their chatbot to ask like a psychologist.

glial··on SIMA 2: An agent that plays, reasons, and learns with you in virtual 3D worlds
https://danijar.com/project/dreamer4/

"We present Dreamer 4, a scalable agent that learns to solve control tasks by imagination training inside of a fast and accurate world model. ... By training inside of its world model, Dreamer 4 is the first agent to obtain diamonds in Minecraft purely from offline data, aligning it with applications such as robotics where online interaction is often impractical."

In other words, it learns by watching, e.g. by having more data of a certain type.

glial··on The brain navigates new spaces by 'darting' between reality and mental maps
Suppose we simplify the scenario and think of experiences as draws from a discrete probability distribution, e.g. p=[0.1, 0.1, 0.7, 0.1].

Suppose further that all events are a draw of type 1, 2, 3, or 4, and that our memory kept a count and updated the distribution - it is essentially a frequency distribution.

When we encounter a stimulus, we have to (1) recognize it and (2) assign a reward valence to it. If we only ever observed '3', the distribution would become very peaked. Correspondingly, this suggests that we would recognize '3' events faster and be better at assigning a reward valence to those events.

Then if we ever encounter a non-3 event, we would recognize it more slowly - it is well-established that recognition is tied to encounter frequency - and do a poorer job assigning reward valence to it. Together this means that we would do a bad job selecting the appropriate response.

Perhaps this scenario-based dreaming keeps us (and rats) primed so we're not flat-footed in new scenarios.

The question then becomes - if these scenarios are purely imagined, where are they being sampled from? If we never observe 1, 2, and 4...how do we know that these are the true list of alternative scenarios?

glial··on Why We Think
In terms of being useful, it depends on the field. In reinforcement learning, for example, the entire field is divided into 'model-free' and 'model-based' approaches. Model-free approaches are learning state-action mappings, which are like habits or 'fast' thinking. Model-based approaches try to build a world model that allows planning and forecasting.

If you're looking for utility in terms of understanding cognition, here are some resources if you're interested - pop-sci books written by cognitive scientists:

- https://press.uchicago.edu/ucp/books/book/chicago/R/bo362751...

Is the division true? Of course not - to paraphrase Box, all models are wrong. But some are useful. This one is useful.

glial··on Gold hits all time high

Seems like anyone who buys or sells gold at any other price is questioning it.

glial··on Bayesian Data Analysis, Third edition (2013) [pdf]
Doing Bayesian Data Analysis by John Kruschke (get the 2nd edition). The name is even an homage to the original.
glial··on Why We Think
Yes, but the overall framework - that our thinking can be broadly divided into habits/reaction and deliberation/forecasting - still holds, with a ton of supporting neural evidence.
glial··on Rereading books
From his Wikipedia page:

Wolfe wrote in a letter, "My definition of a great story has nothing to do with 'a varied and interesting background.' It is: One that can be read with pleasure by a cultivated reader and reread with increasing pleasure."

glial··on Social media promised connection, but it has delivered exhaustion
I'm increasingly of the opinion that ad-driven media is the root cause of many of our social problems.
glial··on Famous cognitive psychology experiments that failed to replicate
The incentive of all psychology researchers is to do new work rather than replications. Because of this, publicly-funded psychology PhDs should be required to perform study replication as part of their training. Protocol + results should be put in a database.
glial··on Forget RAG? Introducing KIP, a Protocol for a Living AI Brain
This is neat - potentially - but the authors should include some benchmarks where this added complexity increases system performance. Otherwise it could be a solution in search of a problem.

glial··on Show HN: Runner – the anti-vibe coding agent
Interesting, will check it out.

A persistent issue I have with Cursor et al. is that they hallucinate function arguments when using a function or method from a library. It seems like automatically pulling the library's documentation into the context would be helpful, but I haven't found any tool that does this automatically. Is there any chance that Runner does this?

It doesn't seem like this was the problem you were trying to solve, but reliable use of libraries and APIs is a critical problem to solve if you want LLM-generated code to work.

glial··on We all dodged a bullet
I had someone from a bank call me and ask for my SSN to confirm my identity. The caller ended up being legitimate, but I still didn't give it...like, are you kidding me?
glial··on iPhone dumbphone
My wife and I put parental controls on each others' phones. I turn them off for travel (in case I need something unexpected) and then back on when I get home. It sounds crazy but it works great.
glial··on Why teach calculus in the age of AI
So much mathematical modeling is based on systems of differential equations. It's difficult to understand the conceptual approach without some basic understanding of calculus.

You CAN model predator-prey dynamics or disease spread using Monte Carlo techniques, but you can't read the historical literature without some grasp of differential equations.

glial··on We’re Not So Special: A new book challenges human exceptionalism
> No other animal is capable of going beyond the confines of this planet, and the fact that only humans can enable such thing is quite exceptional.

One thing humans seem to be uniquely good at is picking goalposts that separate us from other species.

glial··on Show HN: Whispering – Open-source, local-first dictation you can trust
This is wonderful, thank you for sharing!

Do you have any sense of whether this type of model would work with children's speech? There are plenty of educational applications that would value a privacy-first locally deployed model. But, my understanding is that Whisper performs pretty poorly with younger speakers.

glial··on OpenAI Progress
The idea is very close to ideas from Erich Fromm's The Art of Loving [1].

"Love is the active concern for the life and the growth of that which we love."

glial··on Thai Air Force seals deal for Swedish Gripen jets
“Selling the F-35, or American systems for that matter, will certainly become more complicated for American companies,” said Gesine Weber, a Paris-based fellow at transatlantic think tank German Marshall Fund.

“An important factor in the purchase of the F-35 by European governments was the idea that European defense would be built on a transatlantic basis in terms of strategy, institutions and capabilities,” she said, adding that “the Trump administration is in the process of dissolving the transatlantic link, and the purchase of American systems will therefore no longer have any added value for Europeans.”

“If you keep punching your allies in the face, eventually they’re going to stop wanting to buy weapons from you,” said a Western European defense official, granted anonymity to discuss the matter candidly. “Right now we have limited options outside of U.S. platforms, but in the long run? That could change in the coming decades if this combativeness keeps up.”

glial··on The Folk Economics of Housing
Because the value always goes up and managing renters and repairs is a PITA.
glial··on What are the real numbers, really? (2024)
Hopefully someone better educated than me can answer this - several of the definitions in the link feel constructivist, i.e. they describe constructions of of real numbers. It seems easy to think of methods of constructing non-rational numbers, by e.g. using infinite sequences, by taking roots, or whatever.

It seems harder to prove that every real number can be constructed via such a method.

Is there a construction-based method that can produce ALL real numbers between, say, 0 and 1? This seems unlikely to me, since the method of construction would probably be based on some sort of enumeration, meaning that you would only end up with countably many numbers. But maybe someone else can help me become un-confused.
