[Other] Show HN: AGL a toy language that compiles to Go I spent the past 2 weeks making this toy programming language.<p>I basically forked the Go scanner&#x2F;parser, and changed the syntax to have functions return a single value. This enable proper Result&#x2F;Option type to be used as well as propagating errors with an operator.<p>I also wanted to have short &quot;type inferred&quot; anonymous functions to be able to use functions like Map&#x2F;Reduce&#x2F;Filter, without having to use 100 characters to specify the types.

Show HN: Oasis – An open-source, 3D-printed smart terrarium See the website for a demo video: <a href="https:&#x2F;&#x2F;oasis-terrarium.com" rel="nofollow">https:&#x2F;&#x2F;oasis-terrarium.com</a><p>This project is an enclosure for growing plants. Features include:<p><pre><code> - high-power LED lighting - a built-in water tank and mister - fans for airflow - temperature and humidity sensing - wi-fi connectivity and a web-based interface for control and monitoring (see https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;usage_guide&#x2F;#web-interface) </code></pre> The entire project is open-source:<p><pre><code> - electronics: designed in KiCad - 3D models: designed in CadQuery - software: written in Rust </code></pre> I initially started this project during COVID and built a working prototype using a Raspberry Pi and off-the-shelf parts. The first prototype worked, but was pretty rough. Several months ago, I picked up the project again and began a complete re-design. After two rounds of circuit board design and countless iterations of the 3D-printed parts, I&#x27;m finally happy with the results. Along the way I learned a lot about electronics design and fabrication, 3D modeling, and Rust.<p>Happy to answer any questions - thanks for checking it out!<p>Here are some direct links to parts of the project you may find interesting:<p><pre><code> - demo video: https:&#x2F;&#x2F;oasis-terrarium.com - detailed build guide with pictures: https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;build_guide&#x2F; - interactive 3D model: https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;3dmodel&#x2F; - detailed info on electronics design: https:&#x2F;&#x2F;oasis-terrarium.com&#x2F;docs&#x2F;electronics&#x2F; - 3D-printable models: https:&#x2F;&#x2F;www.printables.com&#x2F;model&#x2F;1315117-oasis-smart-terrarium</code></pre>
