It was often brought up in conversations with universities and their libraries - having them made things more convenient. The books were selling for a year or so without ISBNs, no problems either way!

Things like this are why I purchased some ISBNs and self-publish/distribute.

The books (e.g.:Data Analysis with Rust Notebooks[1] and Practical Evolutionary Algorithms[2]) are doing well, and whilst I'm likely "leaving money on the table", I'm happy with how it's going.

Similar for the PlotAPI docs [1] which are all Jupyter notebooks!

Pen plotters are great fun. I set mine up a while ago - a slightly cheaper setup than most https://shahinrostami.com/articles/my-pen-plotter-setup/

I run a plotting/visualization library.

Instead of a time-limited trial, we have just one of the plot types (Sankey) freely available indefinitely (https://plotapi.com/page/sankey/).

We tried a time-limited trial, and we just ended up with people re-registering new accounts every 2 weeks.

Yes! I need to test it on some devices first, then re-register as a play store dev.

My daughter wanted an app like this that would help her with sheet music, so that was enough motivation!

I was tinkering with Unity at the time, so I thought I’d use it to make future releases on other platforms a little easier.

I’ve tested it on a few iPhones, iPads, and a MacBook Air (running the iPad app). It’s worked nicely on those. I don’t recommend using the AirPod microphone as I noticed some poor recognition on the lower notes!

Nice analysis and visualisation! I used a Pareto approach for my exercise and a project I’m working on - https://limitgym.com

I used to write long and technical blog posts. I think it's unlikely someone will go out there way to give you negative feedback, i.e. not constructive.

My motivation came from my younger days where everyone (including myself) had their own little corner of the Internet, made with things like AngelFire and GeoCities. I missed that.

Nowadays, I prefer to make short posts, e.g. [1, 2, 3]. Of course, before I started, I had to write my own static-site generator... It's been years since I've ran my Patreon and I don't post on YouTube like I used to, so there's little to no engagement - which is OK with me.

It doesn't work for me on Safari, macOS, M1: "Error: WebGPU not supported".

WebGL pixels works in the same browser, e.g.: https://plotapi.com/docs/visualizations/terminus/#default-vi...

Official Rust book is great.

If you want to give Rust a go through Jupyter Notebooks, check out https://datacrayon.com/data-analysis-with-rust-notebooks/set...

> Could you elaborate on why you switched away from it?

I started using KaTeX sometime after 2015 because it promised to be fast (the fastest! [1]). I had to change the representation of a bunch of expressions because KaTeX didn't support some environments, whilst MathJax did. It was a trade-off I was willing to accept at the time.

Many years later, I started writing a personal static-site generator. I wanted comparatively lightweight pages, so rendering server-side was an option. I re-evaluated MathJax vs KaTeX again and this time I leaned towards MathJax, as speed was no longer an issue for me. It looks like KaTeX has broader support now [2].

I was using KaTeX for a while on DataCrayon (e.g. https://datacrayon.com/practical-evolutionary-algorithms/pop...), but recently switched to server-side rendering with MathJax.

I'm happy with the way it looks. I'd used KaTeX over MathJax previously because I found it rendered pages faster.

Nice project! I was gifted a pen plotter [1] a while ago and have enjoyed it so far. I would love to build one that supports larger pieces.

I made a VESA mount for my iPad [1]. It wasn't exactly brain surgery [2], but I thought it was cool!

> The major change is building the Jupyter Notebook 7 interface with JupyterLab components so that the two applications share a common codebase and extension system.

This is interesting! Looking forward to testing the purple theme I use [1]. I wonder if extension developers will need to maintain three sets of instructions now? JupyterLab, Jupyter Notebook >= 7, and Jupyter Notebook < 7

I used to write about evolutionary computation, data science, and other tech bits. I'm on my sabbatical right now and mostly writing pieces with no real common theme. I recently wrote my own static site generator - that held me up a little!

I’ve just relaunched https://shahinrostami.com after spending a little too long writing the static site generator that now generates it. That, and https://datacrayon.com, have been the catalyst for several opportunities that have come my way.
