Show HN: Wrote a tiny WebAssembly (wat2wasm) compiler in Go
As a personal project I wrote a really tiny Wat 2 Wasm compiler in Go. Mainly for demonstrative and educational purposes. It was tough: I didn't know anything about WebAssembly internals and I'm a newbie with Go... so I tried to document it as much as I could for anyone that would like to approach the quest in the future!<p>It misses a lot of features (that will be gradually implemented).<p>Any feedback is welcomed!!<p>Demo: <a href="https://luna-demo.vercel.app" rel="nofollow">https://luna-demo.vercel.app</a>
Show HN: I made a volumetric audio visualizer
I'm developing Hyperstep[0], a spatial language for music production. I find using existing DAWs frustrating because they don't allow me to navigate and operate intuitively on the latent spaces behind my musical ideas. This is why I've decided to build my own set of "seeing tools".(Bret Victor)[1]. I'm also convinced that by framing music as processes and interactions in the 3D world, spatialization and mixing should become fairly pain-free.<p>I'm still early in development and I would love to build this into an actual product that can be integrated into existing DAWs or even turn it into a musical framework itself for AR and VR experiences.<p>If you're interested in working on it or if you simply want to know more, feel free to contact me.<p>[0] <a href="https://github.com/a-sumo/hyperstep" rel="nofollow">https://github.com/a-sumo/hyperstep</a>.<p>[1] <a href="https://www.youtube.com/watch?v=klTjiXjqHrQ" rel="nofollow">https://www.youtube.com/watch?v=klTjiXjqHrQ</a>

Show HN: Tier.run – Terraform for Stripe
Hi HN, we are Jevon, Blake and Isaac, we've been working on Tier for a little while ( <a href="http://github.com/tierrun/tier" rel="nofollow">http://github.com/tierrun/tier</a> )<p>Tier is "Terraform for Stripe" but it goes further and gives you feature flag style access checks, and allows you to count/report usage which can be used for metered billing.<p>When we started Tier, we knew that there was something interesting in the SaaS pricing and packaging space. Adjusting price is the single most effective lever a business can use to achieve product/market fit, and there's a strong correlation price nimbleness and market success.<p>In spite of overwhelming evidence of this, most startups pick the price for their product once and then never change it, opting instead to invest in less effective levers like CAC, sales efficiency, "virality", churn, etc. Why?<p>It's just too hard. Any change you make to the pricing model means refactoring not just the entire product, but sometimes the entire <i>company</i>. The path of least resistance leads to a place where there's no single source of truth, and changes anywhere require changes everywhere.After over 50 or so customer conversations and user research chats, this represents our third or fourth implementation (depending on how you count them), and our conception of how best to solve it has been refined and adjusted along the way.<p>The concept of "PriceOps" came out of those conversations, looking at where mature companies end up after several expensive rounds of iterating on how they implement their prices for flexibility and order. <a href="https://priceops.org" rel="nofollow">https://priceops.org</a><p>What we're releasing now is an open source tool you can use to set up your Stripe system that keeps everything organized around a single source of truth. With this, changes to your pricing model don't require changes to your application code or business processes.<p>As a bonus, I think it's actually easier to integrate with than integrating with Stripe the "normal" way. Use the identifiers for your customers and features that you already have. Define plans and subscribe customers to them. No ever-growing pile of object ids to manage.<p>If you are just starting to think about adding pricing to your product, or if you've built something custom but would like something less maintenance intensive, then please give Tier a try and we'd love your feedback.

Show HN: Minimax – A Compressed-First, Microcoded RISC-V CPU
RISC-V's compressed instruction (RVC) extension is intended as an add-on to the regular, 32-bit instruction set, not a replacement or competitor. Its designers intended RVC instructions to be expanded into regular 32-bit RV32I equivalents via a pre-decoder.<p>What happens if we explicitly architect a RISC-V CPU to execute RVC instructions, and "mop up" any RV32I instructions that aren't convenient via a microcode layer? What architectural optimizations are unlocked as a result?<p>"Minimax" is an experimental RISC-V implementation intended to establish if an RVC-optimized CPU is, in practice, any simpler than an ordinary RV32I core with pre-decoder. While it passes a modest test suite, you should not use it without caution. (There are a large number of excellent, open source, "little" RISC-V implementations you should probably use reach for first.)

Show HN: HiSHtory: Your shell history in context, synced, and queryable
hiSHtory is a better shell history. It stores your shell history in context (what directory you ran the command it, whether it succeeded or failed, how long it took, etc). This is all stored locally and end-to-end encrypted for syncing to to all your other computers. All of this is easily queryable via Control-R and via the hishtory CLI. This means from your laptop, you can easily find that complex bash pipeline you wrote on your server, and see the context in which you ran it.

Show HN: I made an offline-ready hiking trail companion app
Hi HN! This is a trail companion web app (think AllTrails) I hacked together in a couple weeks time. I was inspired to create this project while training for an extended backpacking trip. My motivation was to create a UI tailored exactly to my liking, and to be able to track my progress along the trail without draining my battery. I also wanted to experiment with PWA technologies.<p>I successfully used it on my five day adventure along the Knobstone Trail in southern Indiana, and even though it's web-based it hardly consumed any battery life on my old first-gen Pixel XL.<p>It's set up currently to support a single trail, where the trail and trail markers are deployed with the rest of the app. So it's single-use in that way. For future trips, I can simply swap out the GPX files and deploy.<p>I am releasing it with an open source license in case anyone wants to use it as a boilerplate to create their own.
