Finding Your Most Popular Bluesky Followers

I've built a number of demos already using Bluesky's APIs, and for the most part, they're easy to use and "just work" - which is all you want from an API. That was my expectation going into this little demo, but what I was really surprised by was the fact that everything I needed to do could be done without any authentication at all. I didn't need oAuth, I didn't need an API key, I just hit public endpoints and everything just worked.

Mini Logo Interpreter in 100 lines of pure JS

Logo is a programming language designed in the 60s. Its most famous feature is turtle graphics: the programmer controls the "turtle" (cursor) with instructions like forward, left, right, repeat and the turtle leaves a 'trace' on the screen. Today we'll build a compact, single-file logo interpreter in about 100 lines of pure JavaScript. To keep the code short, we'll only implement the four instructions above, plus color_cycle (not part of the standard Logo) that cycles through 36 HSV hues.

Company CEO David Mytton said the release of v1.0 of its Arcjet JavaScript SDK makes it possible for developers to address many of the issues as applications are being developed that DevOps teams would otherwise need to address later in the software development lifecycle (SDLC).
