janpmz··on Show HN: Beautiful QR Codes
The diffusion codes all have a distinctive style where the qr code "melts" into the picture. I wanted to have more dedicated codes.
janpmz··on Show HN: Beautiful QR Codes
With simple prompting it works sometimes but less reliably. I implemented a healing and strengthening algorithm which can improve codes that don't scan quickly.
janpmz··on Show HN: Ilya's 30 papers, explained in audio
Thanks! Links are one cards and on the episode pages too.
janpmz··on 30papers.com – Ilya's 30 essential ML papers, in a beginner friendly format
Ok, thanks for the viewpoint, that makes sense. I use AI summaries every day and find it very valuable. But I also see the trend e.g. on Reddit, that people are very dismissive of ai content.
janpmz··on Local, CPU-Friendly, High-Quality TTS (Text-to-Speech) with Kokoro
Both Text-to-Speech and Speech-to-Text now have local models that are good enough to get the job done. Kokoro for TTS, Parakeet for STT and Fluid-1 for text formatting (I use it with FluidVoice). I hope this is a trend that continues for other applications.
janpmz··on Chat Control 1.0 and 2.0 Explained
Isn't the EU rather like a single point of failure?
janpmz··on All Cars Sold in the EU Now Require a Camera Aimed at Your Face
I wonder if they also have a seeker pointed at my face then, because I don't want that shining into my eyes.

Why do I get downvoted whenever I post something here? Do you think its too spammy? Because its AI? Do I have a downvote bot following me?

After seeing this for the first time, I've build PdfToMp3 to listen to these papers. It has now evolved into ListenDock. Fun fact: PdfToMp3 existed before NotebookLM and I already had "overviews", but I called them teacher explanations.

Here is an example of a "Teacher Explanation" of the paper "Quantifying the Rise and Fall of Complexity in Closed Systems: The Coffee Automaton"

janpmz··on Prefer duplication over the wrong abstraction (2016)
> If they diverge

This is the key, if they are very similar but used by different consumers the chance that they will diverge in the future is very high. And once they do they will break the abstraction.

janpmz··on I used sound waves to make espresso. It could cut coffee‑brewing energy use by ¾
Don't show this to the EU, or they will force us drink only ultrasound espresso from now on.
janpmz··on Ask HN: What are tools you have made for yourself since the advent of AI?
I've been building a PDF -> MP3 tool (web, iphone, android): https://listendock.com/

Then a little calorie-radar-alert app that motivates you to stay on diet before going into a shop: https://apps.apple.com/us/app/stay-lean-calorie-navigation/i...

And to test the hypothesis if the motivation actually works with "fast flashing images" I built this experiment: https://fitfatflix.fit/

When openClaw came out I build a game like map around it to orchestrate tasks: https://memefields.com/

And not published, I build a little recommender app of activities I can do only today or only this time of the year where I currently am, so I don't miss good things.

And some other stuff I'm working on right now :)

janpmz··on Show HN: NoSuggest – Watch YouTube without the recommendation algorithm
You know what would be cool, a "different suggest" that acts like different algorithm.
janpmz··on Show HN: Stay Lean – Calorie Navigation
I had fun making this :)
janpmz··on Tell HN: OpenAI silently removed Study Mode from ChatGPT
I was concerned about big players offering the same functionality when building listendock.com, but maybe there is a place for specialized apps like that.
janpmz··on Music for Programming

janpmz··on Show HN: ListenDock – turn blogs and PDFs into audio
Lately I've been trying to learn about topics more intentionally instead of following what the YouTube feed recommends, for example evolutionary algorithms. For that I built the topics feature in my app, so I get a number of papers and articles suggested and then over the next weeks I can listen to them.
janpmz··on Every layer of review makes you 10x slower
A lot of this goes away when the person who builds also decides what to build.
janpmz··on Show HN: Memefields – Project Map for Bots
Hey, this is my highly experimental project. I’m curious to see the first reactions.
janpmz··on Claude Sonnet 4.6
I got almost the same reply, including the "push it" nonsense:

> Walk! It would be a bit counterproductive to drive a dirty car 50 meters just to get it washed — and the walk will take you less than a minute. You can simply pull the car out and push or walk it over, or drive it the short distance once you're ready to wash it. Either way, no need to "drive" in any meaningful sense for just 50 meters.

janpmz··on Ask HN: What are you working on? (February 2026)
I just published the web app for https://listendock.com You can listen to your documents. I also have an iPhone app (that was first).

My most fun feature: when I connect the app to my car, I can use the skip buttons on my steering wheel to rewind or forward 10s in the playback.

janpmz··on Podcasting Could Use a Good Asteroid
I was also looking for IT-related podcasts and had the same impression. What seems to work is when people write interesting books and then go on shows to promote their books by talking about the content.
janpmz··on Podcasting Could Use a Good Asteroid
> You'll find thousands of shows with perfect audio quality and professional-grade cover art that contain absolutely zero intellectual nutritional value

This is why I switched to audio books. Many podcasts with real guests contained too much salad and not enough meat (e.g. a machine learning podcast but they talked about going to conferences).

Contrary to what many think, I believe AI generated content can increase the nutritional value. I've done experiments with turning technical PDFs into podcasts, e.g. summarizing machine learning papers (similar to NotebookLM).

janpmz··on Ask HN: What did you find out or explore today?
I had some eye strain and think it is because my eye muscles are overused. A doctor told me the muscles in the eye are flat, like tapes, and that I would not feel a muscle ache. I noticed the strain when I focus on different points quickly. I started to pay attention to how I move my eyes and realized I read a lot of text while scrolling, for example reading X posts on mobile while scanning the text at the same time.

Yesterday I was reminded of “Rapid Serial Visual Presentation” for speed reading, where the words are presented so you do not have to move your eyes. I am currently trying it out with a Chrome extension called SwiftRead. I set the text size so it fits into my fovea area. I used a fovea detector website I saw on HN a while ago: https://www.shadertoy.com/view/4dsXzM (make the pattern full screen, then you can see the size of your fovea).

I also learned that I can reduce some of the strain by moving my head more toward the things I am looking at on the screen.

janpmz··on Ask HN: What did you find out or explore today?
Opening the window works well for me.
janpmz··on The struggle of resizing windows on macOS Tahoe
And what to do about the slow mouse?
janpmz··on Contrails Map
Preserving the aesthetics of the sky is reason enough to stop artificial clouds. Why would we accept such a mess?
janpmz··on 10 Years of Let's Encrypt
What else is kept behind paperwork and fees that could be freed?
janpmz··on Has the cost of building software dropped 90%?
At the leafs of the branches I'm comfortable to just generate code (e.g. a popup dialog). But I want to have a good grasp of code that is central of the application.
janpmz··on Simulating a Planet on the GPU: Part 1 (2022)
I wish I had an intuitive understanding of how much I can do with a GPU. E.g. how many points can I move around? A simulation like this would be great for that.
