Who cares about Emacs?

GNU Emacs isn't the oldest interactive text editor for Unix—it's predated (at least) by the Vi editor—nor is it the only Emacs in existence. However, it's surely the most popular Emacs and one of the best editors available on POSIX. Or it was until fresh new editors, like Atom, VSCode, and Brackets, came to the fresh new open source landscape of today. There are so many options for robust text editors now, many of which have iterated upon Emacs' ideas and traditions, that you may well wonder whether GNU Emacs is still relevant. Read more

3-D Printing and Open Hardware: MakerBot, AAScan and RISC-V

  • MakerBot Targets Schools With Rebranded Printers

    MakerBot was poised to be one of the greatest success stories of the open source hardware movement. Founded on the shared knowledge of the RepRap community, they created the first practical desktop 3D printer aimed at consumers over a decade ago. But today, after being bought out by Stratasys and abandoning their open source roots, the company is all but completely absent in the market they helped to create. Cheaper and better printers, some of which built on that same RepRap lineage, have completely taken over in the consumer space; forcing MakerBot to refocus their efforts on professional and educational customers.
