Show HN: Blot – code, art, robots and open source education 8 by apexedison | 3 comments on Hacker News. For the last few years, I've been working at a non-profit called Hack Club developing tools to support self-motivated teens to learn about technology and build community with other like-minded peers while doing so. This has resulted in the development of a model called "you ship, we ship." We build open source creative coding environments, and when teenagers share the projects they make with these tools, we send them materials to dive deeper into the subject and related technologies. Our approach is predicated on the constructionist idea that people learn best by building things they care about and sharing them with others. The vision we have is to create a public collection of creative learning tools that offer people projects they can do right away and communities of practice to engage with.

Show HN: I made a programmable computer from NAND gates 31 by ArchAndStarch | 3 comments on Hacker News. I am proud to present my solo hobby project NAND. This year-long undertaking follows the completed Nand to Tetris course, but ported to the web with its own runtime, user interface, and IDE. Using the "Load example program" selector, you can try out some programs I wrote on NAND's emulated hardware such as 2048, a genetic algorithm, and a manual stack overflow to corrupt the screen. Check out NAND at https://nand.arhan.sh Additionally, I've authored an extensive writeup about the project. Read about it on the GitHub repository's readme.
