Welcome to the 82nd edition

Another week, another newsletter! I hope that you all had a great one 🤩

I’m rarely behind schedule for the newsletter, but this edition was an exception. My right eye decided to stop functioning normally yesterday, so I decided to rest. Earthly bodies are so annoying sometimes. It’s only when we suffer that we realize the luck we have when everything is alright.

Luckily, I managed to watch the first episode of The Rings of Power the day before. Phew!! I don’t even want to know what the critics say about it. I don’t care. I’m a huge fan of Tolkien’s work, so I was delighted to discover a new TV show about it 🎉

I’ve resumed learning and thus started expanding my knowledge base this month. And it feels great to be learning! ❤️

Alright, let’s goooo! 🚀

The Lab 🧪

This week I’ve resumed working for my clients and also resumed work on the Obsidian Starter Kit. I’ve released new versions with tons of new features, new guides, and more will soon follow. During the last 30 days, I’ve sold 36 copies (~$700). So far, I’ve sold > 200 copies (209 at the time of writing), which is a lot more than I hoped when I started this project.

In August I’ve made ~$35 from EthicalAds, mainly thanks to the article that went on the front page of Hacker News.

As planned, I’ve also started testing and tweaking my recording “studio” for the YouTube channel. I’m really delighted with how it looks with my camera and with the Philips Hue lights I bought last month. To go a bit further, I’ve ordered a light and a softbox. This should help better light my face :p

I’m really not used to be on camera, so I’m really struggling, but learning something new is really FUN. Speaking of which, I still have everything to learn about video editing. I could take a shortcut and find someone to help me out, but at least for the first few videos, I want to give it a try on my own.

I still haven’t received all the parts for the new computer, so I can’t show much yet, even if I couldn’t wait to assemble what I already could (case fans, PSU, etc) ;-)

Next week I’ll publish a first YouTube video (an overview of the Obsidian Starter Kit) and will keep working on the Obsidian Starter Kit. I intend to record videos for it and add those as an optional buy for people who want to take the fast lane.

Book of the week

Feynman’s Lost Lecture: The Motion of Planets Around the

This breathtaking lecture―”The Motion of the Planets Around the Sun”―uses nothing more advanced than high-school geometry to explain why the planets orbit the sun elliptically rather than in perfect circles and conclusively demonstrates the astonishing fact that has mystified and intrigued thinkers since Newton: Nature obeys mathematics. David and Judith Goodstein give us a beautifully written short memoir of life with Feynman, provide meticulous commentary on the lecture itself, and relate the exciting story of their effort to chase down one of Feynman’s most original and scintillating lectures.

Stable Diffusion is an open-source alternative to DALL-E. It runs on computers with beefy GPUs (8–12+GB RAM), and also on Apple M1 laptops with some tweaks.

The results are amazing, and the “dataset” required for the engine to generate pretty much anything is so tiny (smaller than a DVD!).

I’m going to give it a try as soon as my new computer is up and running 🎉
