janpmz··on Study: MRI contrast agent causes harmful metal buildup in some patients
Sometimes I wonder if metals in the body can pick up cellphone signals.
janpmz··on Willow quantum chip demonstrates verifiable quantum advantage on hardware
The critics claim the noise collapses quantum states so quickly that it's not possible to make full use of the quantum effects. The burden of proof is on the chip makers. I think they have not convinced the critics yet.
janpmz··on Scripts I wrote that I use all the time
Last month I saw a tweet how to serve files using

python3 -m http.server 1337

Then I turned it into an alias, called it "serveit" and tweeted about it. And now I see it as a bash script, made a little bit more robust in case python is not installed :)

janpmz··on CDC File Transfer
Tailscale and python3 -m http.server 1337 and then navigating the browser to ip:1337 is a nice way to transfer files too (without chunking). I've made an alias for it alias serveit="python3 -m http.server 1337"
janpmz··on F-Droid and Google’s developer registration decree
After developing an app for Android and iOS, it has become clear how wonderful it is to just publish a website in the internet.

In this case, we are less likely to notice our own countries becoming authoritarian. Because we will compare it to a version that is exaggerated.

janpmz··on HN Slop: AI startup ideas generated from Hacker News
I've attempted this with pdftomp3.com where you can listen to PDFs. It has an "AI Explanation" mode where the content of the PDF gets explained. Its like a NotbookLM podcast, but I was earlier :)

Currently I'm working on an app for that, because thats where I listen to the MP3s anyways.

janpmz··on Transparent Electronics
I've heared the part of the processor where the actual processing happens is so thin (0.2-0.3mm) that you might be able to see through it.
janpmz··on Small language models are the future of agentic AI
One could start with a large model for exploration during development, and then distill it down to a small model that covers the variety of the task and fits on a USB drive. E.g. when I use a model for gardening purposes, I could prune knowledge about other topics.

5G signals can be used to track pedestrians on the street, not just ships in the port.

This article is almost unreadable for me. The ads change in size and make the text jump. I'm adding it to NotebookLM now.
janpmz··on Adipose tissue retains an epigenetic memory of obesity after weight loss
I'm not an expert on this topic, so take it with a grain of salt. The reason a low carb diet works for many people (not necessarily extreme keto) is that it reduces the volatility of blood sugar levels, and this results in fewer cravings and being less tired over the day. So taking in fewer calories becomes easier. And then I learned about gluconeogenesis. The body can create glucose on its own and perfectly regulates glucose levels in the brain, etc., once it switches to that mode.

In the end, these tips help to get into a different lifestyle and then reinforce the habits to stay there because it feels better.

janpmz··on Adipose tissue retains an epigenetic memory of obesity after weight loss
I don't understand why I get downvotes for that. Those are the things I did in the past two years to get to my dream weight and hold it without yoyo effect.
janpmz··on Adipose tissue retains an epigenetic memory of obesity after weight loss
For me weightloss worked over a long period of time with a couple of strategies.

1. One was not eating breakfast, this works well when I'm in the office. Then you have fasting built into your daily routine. This has many metabolic benefits.

2. Switching to a low carb diet (keto). I never thought I'd quit eating bread, but reducing carbonhydrates (esp. sugar) and eating more eggs & meat had the biggest effect on my weight. More so than doing sports. This is just a rough guideline, I don't follow this very strictly.

3. Sports + Fasting: Sometimes on the weekends I go on a hike or do some sports and only eat when I get home in the afternoon (e.g. steak). This forces my body to take the energy from the fat reserves.

janpmz··on Albert Einstein's theory of relativity in words of four letters or less (1999)
Ah, I just want to clarify that I'm very unhappy about the censoring of "dumb" and "hell".

I allow the text to get slightly optimized for audio experiences, e.g. page numbers or mathematical notation gets replaced. But I have think about that again.

I turned this into a little audio book: https://www.pdftomp3.com/shared/67fcc7f933aa6c3115b114da
janpmz··on 2025 AI Index Report
For almost everyone I think. Since the industrial revoultion we have availability of cheap electricity, cheap lighting, an abundance of food and clothing etc. How the wages developed is something I don't know.
janpmz··on 2025 AI Index Report
What I'm certain of is that the standard of living will increase. Because we can do more effective work in the same time. This means more output and things will become cheaper. What I'm not sure of, is where this effect will show in the stock market.
janpmz··on The case against conversational interfaces
Speaking and pronouncing words feels like more effort and requires more attention than typing on my keyboard or moving the mouse.
janpmz··on The Great Barefoot Running Hysteria of 2010
During hiking, I realized that I’m more likely to tip over in my hiking boots compared to my sneakers. The center of pressure is much higher in hiking shoes than in sneakers. And the shape of my sneakers is roughly like a triangle, with the larger side on the bottom. It's a different stroy when its muddy though...
janpmz··on Show HN: Listen to PDFs in Any Language
Recently I’ve learned that if you listen to audiobooks in your field of expertise every day on your commute, you might pick up a semster worth of education in a year.
janpmz··on The Lost Art of Research as Leisure
I would have published on arXiv, but to do that you need an endorsement from an established arXiv user in that specific category. And even then, you can only submit papers in that category. On Zenodo, I was able to publish quickly, and I like that I can see the number of views and downloads.
janpmz··on The Lost Art of Research as Leisure
I did some leisure research on how the Nazca Lines align with mountain shadows and made a publication. That was a nice weekend. https://zenodo.org/records/11422308
janpmz··on Deep Learning Is Not So Mysterious or Different
You can listen to an explanation of the paper here: https://www.pdftomp3.com/shared/67d8abf0ecf38326f8973e49

I created this tool last year to listen to a machine learning book, now I use it for ML papers. The explanations are still a bit repetitive, its not perfect yet.

janpmz··on Opposing arrows of time can theoretically emerge from certain quantum systems
How long will it take for people to realize, they are looking at a contradiction?

janpmz··on Willow, Our Quantum Chip
I've heared claims before that quantum computers are not real. But I didn't understand it. Can anybody explain the reasoning behind the criticism? Are they just simulated?
janpmz··on The Eukaryote, the First Cell to Get Organized
