What is Dithering?
Dithering is a method for trying to make an image look good while reducing the number of colors it uses, or as wikipedia puts it:
Dithering is used in computer graphics to create the illusion of "color depth" in images with a limited color palette - a technique also known as color quantization. In a dithered image, colors that are not available in the palette are approximated by a diffusion of colored pixels from within the available palette. The human eye perceives the diffusion as a mixture of the colors within it (see color vision). Dithered images, particularly those with relatively few colors, can often be distinguished by a characteristic graininess or speckled appearance.
For more information, see this list of dithering resources from around the web: explainers, algorithms, examples, etc.
About this site
Dither it! is built by Alex Harris.
It was inspired by a blog post from Low-tech Magazine about how to reduce the energy usage associated with running websites. One method discussed was to reduce full color images to dithered images with very few colors and subsequently smaller file sizes. Ensuing discussion clarified that there are other, more modern ways to compress images (try Squoosh) which achieve reduced file sizes while maintaining color. Nonetheless, dithering is a fun technique that looks cool and is interesting to learn about.
The Dither it! source code is freely available on the Dither it! Github page. Please feel free to contribute, share or pilfer.
Thanks to Leon Sorokin, for making RgbQuant.js and Don for making vue-color.

Technitium DNS Server is an open source authoritative as well as recursive DNS server that can be used for self hosting a DNS server for privacy & security. It works out-of-the-box with no or minimal configuration and provides a user friendly web console accessible using any modern web browser.
Nobody really bothers about domain name resolution since it works automatically behind the scenes and is complex to understand. Most computer software use the operating system's DNS resolver that usually query the configured ISP's DNS server using UDP protocol. This way works well for most people but, your ISP can see and control what website you can visit even when the website employ HTTPS security. Not only that, some ISPs can redirect, block or inject content into websites you visit even when you use a different DNS provider like Google DNS or Cloudflare DNS. Having Technitium DNS Server configured to use DNS-over-TLS, DNS-over-HTTPS, or DNS-over-QUIC encrypted DNS protocols with forwarders, these privacy & security issues can be mitigated very effectively.

PocketBase was created to assist building self-contained applications that can run on a single server without requiring to install anything in addition (see Presentator#183 ).
The basic idea is that the common functionality like crud, auth, files upload, auto TLS, etc. are handled out of the box, allowing you to focus on the UI and your actual app business requirements.Please note that PocketBase is neither a startup, nor a business. There is no paid team or company behind it. It is a personal open source project with intentially limited scope and developed entirely on volunteer basis. There are no promises for maintenance and support beyond what is already available (you can explore the Roadmap to get a general idea where the project is headed but there are no fixed ETAs).
