haffi112··on Why are large language models so terrible at video games?
They are also pretty bad at navigating mazes (which can be somewhat similar in spirit to text adventures where you need to navigate through text): https://arxiv.org/abs/2507.20395
haffi112··on Habitual coffee intake shapes the microbiome, modifies physiology and cognition
I stopped drinking coffee for four or five years. I drank a lot before. You do realise that it has a strong psychoactive effect, at least it did for me.

I still don't drink coffee, but I started experimenting with paraxanthine and I absolutely love it (paraxanthine is the primary metabolite of caffeine and is also a stimulant). I feel like it gives me most of the benefit of caffeine with very few downsides (no jitters, no crash, exits your system faster).

haffi112··on Semantic ablation: Why AI writing is generic and boring
Oh the irony, I also felt that way when I started reading it. It borders on being hypocrisy given the topic of the article.
haffi112··on Skills Officially Comes to Codex
What are your favourite skills?

You can find a demo here: https://huggingface.co/spaces/facebook/omniasr-transcription...
haffi112··on Artificial Writing and Automated Detection [pdf]
Even if it was close to being near perfect, that is still not enough due to the negative impact of false positive detections on students.
haffi112··on Artificial Writing and Automated Detection [pdf]
That's where the humanizers come in. These are solutions that take LLM generated text and make it sound human written to avoid detection.

The principle of training them is quite simple. Take an LLM and reward it for revising text so that it doesn't get detected. Reinforcement learning takes care of the rest for you.

haffi112··on Vibe coding has turned senior devs into 'AI babysitters'
Why do the news need to make everything sound sensational. Let's move on.
haffi112··on Cognitive load is what matters
The section on nested ifs reminded be of being a Nevernester: https://www.youtube.com/watch?v=CFRhGnuXG-4 (it's a short [~8 min], fun watch)
haffi112··on GPT-5
It makes it look like the presentation is rushed or made last minute. Really bad to see this as the first plot in the whole presentation. Also, I would have loved to see comparisons with Opus 4.1.

Edit: Opus 4.1 scores 74.5% (https://www.anthropic.com/news/claude-opus-4-1). This makes it sound like Anthropic released the upgrade to still be the leader on this important benchmark.

haffi112··on Springer Nature book on machine learning is full of made-up citations
You would think that Springer did the due diligence here, but what is the value of a brand such as Springer if they let these AI slops through their cracks?

This is an opportunity for brands to sell verifiability, i.e., that the content they are selling has been properly vetted, which was obviously not the case here.

haffi112··on Energy drinks linked to rise in colorectal and blood cancer
Taurine deficiency has been claimed to be a driver of aging [1]. The claim from the news article about it possibly being related to cancer seems like it needs a much stronger justification.

haffi112··on A Research Preview of Codex
(watching live) I'm wondering how it performs on the METR benchmark (https://metr.org/blog/2025-03-19-measuring-ai-ability-to-com...).
haffi112··on Ask HN: Is Cursor deleting working code for you too or is it just me?
It has happened to me on very large files and when you've had a long composer session. I usually check every file that is being modified for large removals because of this. It's a bit annoying, but something I can tolerate.
haffi112··on Higher potassium intake at dinner linked to fewer sleep disturbances – study
The original website is a news report of an article. The one he posted is from a peer-reviewed journal which has a much higher standard of reporting. The information there is reported by scientists with expertise in the field. You cannot expect the same level of rigour from journalists that try to sensationalise findings to get more clicks.
haffi112··on Cognitive load is what matters
This post reminded me of Nevernesting: https://www.youtube.com/watch?v=CFRhGnuXG-4
haffi112··on Ask HN: What are you working on? (October 2024)
Looking forward to see that project on air quality.
haffi112··on X becoming a 'ghost town' of bots as AI-generated spam content floods internet
For what I follow, it looks genuine.

However, for many viral posts, many of the responses have nothing to do with the original post. It looks like bots/users that are riding off of the success of the viral post in an attempt to get more views/likes/followers. It's a sad behaviour that lessens the experience of the platform.

haffi112··on Wasabi linked to "substantial" boost in memory, Japanese study finds
It has been grown in Iceland: https://www.nordicwasabi.com/
haffi112··on Collection of "Today I Learned" notes
If you're using a Mac, I really recommend alt-tab https://alt-tab-macos.netlify.app/.

I love cmd+tab on a mac to switch between applications, but I was missing a feature to switch between windows of the same application. Alt+tab solves that in the same manner Windows does.

haffi112··on Finland's ChatGPT equivalent begins to think in Estonian as well
Thanks, that's great to know. Do you know how they would compare if you performed training instead of inference?
haffi112··on Finland's ChatGPT equivalent begins to think in Estonian as well
Isn't that going to be a problem with no NVIDIA GPUs?
haffi112··on IKEA bomb shelter furnishings catalog by Midjourney
Looks like mode collapse in Midjourney. It is less capable of dealing with instructions now likely to increase the chance of generating aesthetically pleasing output.
haffi112··on OpenAI expects GPT-5 to achieve AGI
You may have an opinion, but can you justify why you don't believe chatGPT will achieve AGI?

Existing scaling laws show that perplexity (i.e., ability to predict next tokens in text) can be lowered by increasing model size and adding more data.

Why would a model that is better than us at predicting what words would occur next in arbitrary text not be an AGI?

haffi112··on Moore's Law for Everything (2021)
Governments that implement these type of policies might see a rapid rise in their GPD. If it works out, I assume others would follow.

But what country would be the first one to take the leap?

haffi112··on Algorithms to Live By – The Computer Science of Human Decisions
I also recommend other books by Brian Christan, especially the Alignment Problem.
haffi112··on Tell HN: If you have trouble focusing on projects/meetings, see a psychatrist
What made you decide to get tested for it?
haffi112··on Tell HN: If you have trouble focusing on projects/meetings, see a psychatrist
Some people don't experience anxiety from caffeine whereas others do.

This effect has been linked to polymorphisms on the A2a receptor gene (https://pubmed.ncbi.nlm.nih.gov/12825092/).

haffi112··on Ask HN: Do you regret being a generalist?
Being a generalist is a lower risk strategy than being a specialist from a portfolio management perspective, i.e. investing how you spend your time.

If you specialize in something and it stops being relevant you might have little marketable skills to contribute. This would be like putting all the eggs in the same basket.

If you are a generalist you are protected from such a scenario since you put the eggs in several baskets.

But as a generalist you might be missing specialist opportunities so, of course, it's a bit of a tradeoff.

In this sense, it can be rational to be a generalist. However, every person's experience is unique so it's hard to say that one thing is better than the other without further context.

haffi112··on Ask HN: What's your favorite board game?
I have played really many boardgames but I think Isle of Skye is the game that is probably the one I would choose as my favorite one. It has a relatively simple auctioning mechanic and the point system makes it different every time.
