The Small Internet

The Website Obesity Crisis
Recommended read if you don't know about the extent to which the web is unjustifiedly bloated, and how it's affecting you and others.

Project Gemini FAQ
If you liked the last read, take a look at Project Gemini: Geminispace is another Internet of sorts, very early at the moment (2021), with less than 2000 capsules (how websites are called in Geminispace). Gemini is a protocol that doesn't support Javascript or CSS: this is with anticapitalist and accessibility (visual and technological) objectives in mind.

The beautiful client I use to browse Geminispace (see above). For Linux, Windows and MacOS.

Solar-powered website about low-tech solutions to many aspects of life. The sections about setting up a solar-based server are of particular interest.
Read with caution: They have expressed anti-vaccine and anti-medication ideas in the name of low tech, in an article I read.

Search engine for curated websites. It returns less results than most other search engines, but they are of higher quality. "In the early days of the web, pages were made primarily by hobbyists, academics, and computer savvy people about subjects they were personally interested in. Later on, the web became saturated with commercial pages that overcrowded everything else. [...] Google isn't great at finding them, its focus is on finding answers to technical questions, and it works well; but finding things you didn't know you wanted to know, which was the real joy of web surfing, no longer happens".

Bear and Mataroa Both are very good minimalist blogging platforms. Very fast, without any trackers or ads. I specially like Mataroa.

Online, free replica of Photoshop from the horrible company Adobe.

A color palette generator.

Color blender
To blend and pick colors in Hex or RGB format, with up to 10 midpoints.

Dither Me This and Dither it!
To dither images (it makes them weigh less). Dither Me This has some functions that Dither it! lacks, but the latter has a useful palette import/export feature.

Contrast finder
Finds correct color contrasts for web accessibility.

The best free collaborative drawing program that I know of. With functions similar to GIMP, Photoshop or Krita, but it allows multiple users to remotely work in the same canvas. Great for a digital drawing party.


Online, tiny but great game engine for those that want to create little stories and worlds but do not have experience with more complex game engines. It's what I used to create some of my games.

Disposable temporary e-mail adress generator: to avoid spam when forced to provide an e-mail adress to download something, for example.

Math and programming

If you're an artist looking to get into programming, I recommend starting here. "Processing is a flexible software sketchbook and a language for learning how to code within the context of the visual arts. Since 2001, Processing has promoted software literacy within the visual arts and visual literacy within technology".

W3Schools One of the best places to learn html for free, among other things.

Algorithmic Botany
The website of the University of Calgary's Biological Modeling and Visualization research group, containing software and publications about the modeling, simulation and visualization of plants through code and math.
I especially recommend their free book The Algorithmic Beauty of Plants, about L-Systems, fractals and plants.

Learn X in Y minutes
Very quick tours on many different programming and markup languages, with links for further reading. Good for deciding what to learn next.

"[Beautiful, interactive site] to play and listen to how [40] different musical scales sound. [...] They have roots from cultures all around the world and some have been in existence for over 50,000 years. The pitch constellation circle will tell you where the tones are situated within an octave and I've included the frequencies for each scale [as well as some information about them]".

Collection of prerendered FFVII backgrounds
Prerendered backgrounds are mostly used in old games due to their limitations. They're static images placed beneath the characters, instead of real-time renders of scenery poligons. They don't permit camera movement but are faster to make, allowing for detailed scenes.
