Now, if you have been following the development of EndBASIC, this is not surprising. The defining characteristic of the EndBASIC console is that it’s hybrid as the video shows. What’s newsworthy, however, is that the EndBASIC console can now run directly on a framebuffer exposed by the kernel. No X11 nor Wayland in the picture (pun intended).
But how? The answer lies in NetBSD’s flexible wscons framework, and this article dives into what it takes to render graphics on a standard Unix system. I’ve found this exercise exciting because, in the old days, graphics were trivial (mode 13h, anyone?) and, for many years now, computers use framebuffer-backed textual consoles. The kernel is obviously rendering “graphics” by drawing individual letters; so why can’t you, a user of the system, do so too?

This opens up a lot of interesting use cases and fun hacks for developers to implement in their CLI applications. All the code in the article is – as usual – way over my head, but will be trivial for quite a few of you.
The mentioned EndBASIC project, created by the author, Julio Merino, is fascinating too:
EndBASIC is an interpreter for a BASIC-like language and is inspired by Amstrad’s Locomotive BASIC 1.1 and Microsoft’s QuickBASIC 4.5. Like the former, EndBASIC intends to provide an interactive environment that seamlessly merges coding with immediate visual feedback. Like the latter, EndBASIC offers higher-level programming constructs and strong typing.
EndBASIC’s primary goal is to offer a simplified and restricted DOS-like environment to learn the foundations of programming and computing, and focuses on features that quickly reward the learner. These include a built-in text editor, commands to manipulate the screen, commands to interact with shared files, and even commands to interact with the hardware of a Raspberry Pi.

Being able to run this on a machine without having to load either X or Wayland is a huge boon, and makes it accessible fast on quite a lot of hardware on which a full X or Wayland setup would be cumbersome or slow.
