fxwin··on The Little Book of Reinforcement Learning
definitely the latter, it is even referenced in the foreword:

> Its goal is not to be exhaustive, but rather minimalist and easy to read. For this reason, it follows the format of The Little Book of Deep Learning [Fleuret 2023]. Its tone, however, is closer to that of a blog post, as the book is built around a single narrative thread. Its structure broadly follows that of Sutton and Barto’s Reinforcement Learning: An Introduction [Sutton et al. 2018], which remains the canonical reference on the subject.

fxwin··on German AI consortium releases Soofi S, an open 30B model that tops benchmarks
looks like they have since fixed the dataset, hope they release an updated report (either without the leaked evals or a new checkpoint/weights)

I think the real challenge is to figure out wtf you're actually supposed to do from all this flowery over the top claudespeak
fxwin··on Proof of care in the age of AI
> The reality is people don't always care if a human poured their heart and soul into something.

That's fine, but I don't think the author would suggest writing e.g. library documentation by hand. It's clearly advice for the creator side of the problem of low signal-to-noise ratio in the digital space and how to stand out/signal, rather than a general rule

fxwin··on Proof of care in the age of AI
That was a fun read! I caught myself almost skimming the first part until i got to the mirrored paragraph, and slowed down significantly after that to read more deliberately.

I'm not sure how much actual advice one can take from this essay though beyond "use personal commitment (e.g. time or presence) to signal importance/care" and "go offline" (aka touch grass)

fxwin··on Migrating a production AI agent to GPT-5.6: 2.2x faster, 27% cheaper
>For four months, no frontier model beat Claude Opus in our production evals

What do you think that is referring to?

fxwin··on How to build a circular LCD clock
> The Pi 3B+ seems just enough to render some simple animations.

> I think a Pi 4 might be a good sweet spot between processing power and price,

I know this isn't exactly a serious product and more of a gadget/gimmick but man we are off by a factor of like 3-4 here :D

fxwin··on Migrating a production AI agent to GPT-5.6: 2.2x faster, 27% cheaper
I would expect they have production based datasets they evaluate new models against.
fxwin··on Show HN: Mindwalk – Replay coding-agent sessions on a 3D map of your codebase
Tried exploring a small project i built with CC, but i don't see anything in the tree/terrain view (The edits/reads/writes do show up in the timeline). The project itself doesn't exist on my drive anymore, is that a requirement?
fxwin··on A global workspace in language models
fwiw o1, o3 and 4.1 also give the correct answer (without web search)
fxwin··on A global workspace in language models
I'm not sure which chatbots you used, but OpenAI's o3, o1 and 4.1 get it right first try (used in the Playground without web search or any other tools).
fxwin··on What Emily Bender meant by "stochastic parrots"
Sure, but that's the nature of language (which is also why i put "understand" in quotation marks. I usually follow it up with "whatever that means" lol) . I think in this case, it carries with it implicit properties (abstract semantic representation) that i think models possess, which a decoder doesn't.
fxwin··on What Emily Bender meant by "stochastic parrots"
I think "(intelligent) language understander" is an apt term. It contains within it the fact that these models are mainly trained on text, and "understand" it beyond a simple token-by-token level (i.e. their latent space maps to more and more complex concepts).

It also separates them from "world understanders" since any understanding they might have about the world comes from text (or images if we include multimodal models). They do not gather experience, memories or other "qualia" that many people (me included) would probably include in a definition of human experience/intelligence.

(fwiw i think artificial intelligence is a good, broad term, but it is both too broad to describe the current sota, and too loaded nowadays to be using in nuanced discussions)

fxwin··on The gauge broke: devs felt 20% faster with AI, measured 19% slower
Have they retracted it? My understanding was simply that they released results with more recent data, not that this study itself was flawed (and their website doesn't mention a retraction either)
fxwin··on Tidal AI Policy
And i would consider this as an agent doing things under human instruction
fxwin··on Tidal AI Policy
I'm not sure which part of my comment comes across as fence sitting to you, but to clarify:

- I think there are good and useful ways to use AI in art creation

- I also think that AI (especially end to end creation of full songs) is a massive problem for both content moderation and business model aspects of this type of platform

- I don't think a blanket ban on AI in <Field X> is a good idea (even a bad idea in almost all cases)

You can disagree with these three points and that's fine, but it's not fence sitting when someones position isnt 100% one way or the other

fxwin··on Tidal AI Policy
I work with coding agents every day, I don't think they have ever started working on a project without me telling them to
fxwin··on Tidal AI Policy
> Laws and rules exist to serve humans, not machines.

Machines don't go out on their own to create and upload music, they do so under human instruction, so their output should be policed the same way we police other machine generated output directed by humans.

fxwin··on Tidal AI Policy
The issue i have with it will depend heavily on implementation, i can see cases where songs that i would consider "produced and written" by people don't qualify for royalties under Tidal's guidelines. (I intentionally left out the "performed" part, since digital music production is way past the point where this was an easy and/or meaningful distinction)
fxwin··on Tidal AI Policy
> Tidal will accept AI-generated music.

> Tidal will hold AI-generated music to a higher standard of content integrity. We will not tolerate AI-generated music that exploits an individual’s or group’s music, name or likeness, deceives listeners, or diminishes the quality of our service.

I think this is a very reasonable approach, and probably also the best way to treat AI-powered copyright infringement as a whole. Just like we don't penalize artists for consuming content unless they produce actually infringing content, we should set the same focus for AI systems.

> Starting today, AI-generated music will not be monetizable. We are only in the beginning of the era of AI-generated music.

Don't really agree that this follows from the stated principle here ("... ensuring royalties go to original works produced, written and performed by people"), but will definitely help with spam etc.

fxwin··on Model Training as Code
fwiw aleph alpha have been around since 2019
fxwin··on Steam Machine launches today
> Those are specs that belong on a laptop or a lowend console offering like the Series S.

Unfortunately, valve (and we consumers) have to recalibrate our understanding of which prices qualify as "insulting".

fxwin··on Hetzner Price Adjustment
Me, a german, looking at my CAX11: this doesn't seem too bad

fxwin··on How Terry Tao became an evangelist for AI in math
I think it helps his credibility that he has been working with and speaking positively about AI assisted mathematics (especially for formalizing proofs) for over a year now . I'm sure he isn't unbiased, but as far as spokespeople in the AI space are concerned I'd count him among the less biased ones.
fxwin··on Apache Burr: Build reliable AI agents and applications
The advantage of frameworks isn't that they make it easier to write the actual agent, it's tooling + observability + ... Even Langchain, for all the (deserved) criticism it gets made this very clear very early: It might be easy/easier to write your own chatbot from the ground up, but what happens if you have to add observability/tracing? Being able to just add one environment variable and instantly have a UI where i can nicely go through all of my traces with basically 0 additional effort is something a hand rolled solution just can't really compete with
fxwin··on Ask HN: Is the web for machines (/llm.txt) the one we wished we had as humans?
here: https://llmstxt.org/ and obviously it doesn't automatically produce markdown, it's something the website needs to provide (e.g. https://pydantic.dev/llms.txt)
fxwin··on A Post-Quantum Future for Let's Encrypt
Well similar to how turing machines are a sufficient theoretical model to make all kinds of arguments about runtime complexity of classical computers without relying on their actual physical implementation, we have theoretical models for the way we are approaching quantum computation that do the same thing (Namely the quantum circuit model)
fxwin··on Webcam head tracking, webcam to control in‑game FOV
Hmm, from the title i expected a tool to calibrate FOV angle to monitor size/distance
fxwin··on Taking a walk may lead to more creativity than sitting, study finds (2014)
In german, there is an idiomatic way of saying "I don't understand" (especially after attempting to do so multiple times) that literally translates to "Standing on the hose/tube", which is extra fitting here considering that, in both cases, a fix consists of getting up and walking away ;)
fxwin··on Energy return in running shoes explained (2025)
Of course it is beneficial in the long run, but beginners are still prone to overtraining and getting injured when they go from sitting a desk for 14 hours a day to running 3 times a week
