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.

Show HN: A tool to help you remember shit you are interested in
I've been working on Recall for a while now, it had some initial traction in the beginning which has since died down now. I am facing the inevitable question of whether to continue with the project. I just put out a new release and it would be helpful to get advice from the community on what they think of the idea and my implementation.

Show HN: A Levels.fyi for Contracting/Freelancing
I've been working on this the last few days after seeing a post on reddit calling for this exact website to exist. I'm hoping the email-less/account-less and open data might be appealing.<p>I'd love any feedback you might have, and of course if you were to volunteer some data ;)<p>I'm aware it looks bad on mobile atm.
Show HN: Hyper minimalist habit tracker for Chrome
I'm an undergrad at cal who's trying to get better at React and building apps. I'd love any feedback on the general UI and user experience, new to coding products!<p>If you don't want to download it, but still want to give me feedback, app demo vid & pictures in official launch <a href="https://tinyurl.com/reactlaunch" rel="nofollow">https://tinyurl.com/reactlaunch</a><p>Please let me know your thoughts, critical or supportive! Looking to learn
Show HN: A small, weird and unpractical programming language
I've been spending some time coding fp. It is a programming language heavily inspired by the language John Backus described in his 1977 Turing Award lecture.
There's plenty of examples in the projects github repository for the interested!
Show HN: Explainpaper – Explain jargon in academic papers with GPT-3
heyo! Explainpaper lets you upload a research paper PDF. If you don't understand a formula or sentence, just highlight it and the tool explains it for you<p>I built this a few weeks ago to help me read a neuroscience paper, and it works pretty well! I didn't fine-tune GPT-3, but I do take a lot of context from the paper and feed that into the prompt (not the whole paper).<p>Ppl have uploaded AI, biology, economics, philosophy papers and even law documents. Works in Chinese, Japanese, Spanish, French and more as well!
