“Explaining the Internals of Async-Task from the Ground Up,” n.d. https://notgull.net/async-task-explained-part1/

Great article on how "async-task" works in Rust.
I’m not an expert on Rust, but I guess I don’t have to be. The explanation made by the author is actually applicable to many languages which also offer "async" data processing.

“How to Fertilize Houseplants,” n.d. https://gardenerspath.com/plants/houseplants/fertilize-houseplants/

My fiancé started to grow some #plants and we both started to research what are the best ways to keep our plants healthy. #gardening
In this post, I’ll make a note for myself on what to do and what not to do while fertilizing plants.
Plants can synthesize sugars, fats, and proteins but can’t make mineral nutrients. Primarily Nitrogen (N), phosphorus (P) and potassium (K).
Store bought #fertilizers have labels like 10-10-10, which means N-P-K. #npk
Nitrogen is essential for biosynthesis of proteins and is a central component of chlorophyll. Add more of it, and you will achieve rapid growth and foliage development.
Phosphorus is needed for photosynthesis and energy transfer. Use for root development and flower, fruit and seed formation.
Potassium required for regulation of response to light.
Ok, this sounds as if bullshit, but the article does not provide sources for it. Probably it’s much more complex, just as B12 in humans.

“Https://Jamesgurney.substack.com/p/How-to-Draw-a-Gorilla-Portrait,” n.d. https://jamesgurney.substack.com/p/how-to-draw-a-gorilla-portrait

Have you ever tried to draw a living specie? I tried cats and when they don’t move it’s actually simple. When it comes to gorillas, it’s apparently more tricky!
You need to behave and give some impression of what you are going to do. Interesting blog post and great gorilla portrait!

“Afternoon Project: JPEG DCT Text Lossifizer,” n.d. https://lcamtuf.substack.com/p/afternoon-project-jpeg-dct-text-lossifizer

Someone used Discrete Cosine Transform to apply compression on text.
What is fascinating about it is that compressed text sometimes is not readable by humans at all, and LLM can pretty well parse it to original text!
Anyway, I found this person’s blog and started to read ever blog post he/she/they made.

“Radios, How Do They Work?,” n.d. https://lcamtuf.substack.com/p/radios-how-do-they-work

Elementary blog post which introduces core concepts of radio antennas and modulation.
I never heard about this comparison of capacitor and antenna. Also, the way author describes it seems like a breeze.

“Linux Crisis Tools,” n.d. https://www.brendangregg.com/blog/2024-03-24/linux-crisis-tools.html

List of unix tools that you can use during server issues. #server #linux #issues #perf
