3D printing experiment: I designed a little adapter to add a flashlight to my Swiffer. I call it the "Swiffer Explorer" now.

Did a recent Android update break the File Access API in Chrome? On Android 16 with Chrome 142.0.7444.48 I get:

"Failed to execute 'showOpenFilePicker' on 'Window': The user aborted a request."

Google's own FSA demo also stopped working:

Today I felt inspired to write down some thoughts about the current state of LLM-based coding and about a prompt coding experiment I am conducting:

In the era of AI, the intelligence of a country will be equal to

electricity * chips * software

Not sure how it will look on the chips and software front. But in terms of electricity, China seems to be hard to catch up with.

The html-editor with instant preview is still my favorite tool to do HTML/CSS/JS experiments on the go.

no-gravity.github.io/html_editor/

So I added a some more features today to make it more convenient.

With the json arrow functions, SQLite makes a nice document store. If you have a json "book" column, then selecting all book names is just:

SELECT book->>'name' FROM books;

But I miss auto increments.

Without an additional 'id' column, inserting a new book with a unique id is tricky.

I started adding additional infos on the www.productchart.com item pages when hovering the data fields with the mouse.

The iPad Pro has a nice aspect ratio of 1.33. Most tablets are at 1.6. I think the more squarish, the better for coding.

It is also nicely lightweight at 578g for the 13" version.

From a usability standpoint, the AT Protocol is really nice. You prove ownership of a domain simply by placing a text file containing your DID string on it. The domain then becomes your handle.

One Year Later ...

#AI: I did it! I finally surpassed Reddit!

#ChatGPT: Haha, I'm already ahead of you!

#Bing: Wait, I'm still trying to figure out how to make a simple web interface!

#Bard: I'm Gemini now! Wait for me!

My favorite test prompt for AI coding tools:

Make a simple HTML page which uses the VideoEncoder API to create a video that the user can download.

So far, not a single AI has managed to create a working solution.

I just discovered that with nested CSS and :has(), you can now restyle any aspect of a page based on whether a certain checkbox is set.

Pretty useful.

Last year, I created an Instagram account to serve as a calendar for art events at small galleries in Hamburg that interest me:

Some people started following it and the growth even looks exponential.

Current experiment:

Turning the fitness app into a dance app with dance teacher and choreographer Noah Tepe (notheape.com)

Added a first additional widget for this project: A tool to have a slowmo video and a full speed video with countdown to dance along.

I thought about how the logo of the list-app could look like and came up with this.

The idea is that it means "Lists of lists and lists of lists of lists - lists all the way down".

I wonder if this is a logo design that is already in use somewhere?

I made a custom fitness app for myself recently:

x.com/marekgibney/...

I got so accustomed to the interface that I consider making a to-do list app in the same style.

The sorting functionality is already sorted.

Every time I have a cold, I tinker with a project that I call "Medichart". It's a bit like Product Chart, but for medical studies.

The idea is to retrieve all studies related to a topic, categorize them via AI, and then produce an overview of the current state of research.

My HTML editor with instant preview just got a tad better.
Previously, the JS state stuck around between runs. Causing problems, for example when you define a global variable with let.

Now the output frame gets recreated on every update, which fixes it.

Product Chart sorts products using 2 axes instead of 1, resulting in an x/y chart.

On mobile, there is no space for the chart, just a list. So far, I did not get around to add even one sort option to the mobile version. So desktop had 2 and mobile had 0.

I finally changed that.

📢 Announcement from the #3FeaturesPerWeek department:

On www.gnod.com/search, shift+enter now activates multiline mode.

Shift+enter seems to become the standard to switch search from singleline to multiline. Google and Bing support it already.

📢 Announcement from the tiny-random-feature department:

If you ever feel the urge to be presented with a random 🎶band, 🎬movie or 📚author - there is a link for this on the help pages of music-map.com/info, movie-map.com/info and literature-map.com/info now.

Week 46 of measuring my steps

Back above 10k daily steps.

The winter dip brought the linear regression down to only 6 additional daily steps per week 😲

So much for the pitfalls of simple linear regression and seasonal effects.

Curious how it will look like after 52 weeks.

Week 45

The #walking project completely fell off a cliff in November.

Cold weather, lots of rain, wind and snow here in Hamburg made it just too uncomfortable.

Average for the whole year 2023 was 9511 daily steps.

Very much looking forward to continuing the project this year!

Prediction:

The New York Times lawsuit will have no significant impact on OpenAI.

The value of AI lies in its growing ability to automate all human work. And most human work does not depend on having access to news articles.
