Show HN: Our space game has a built-in RISC-V emulator that runs Linux We're a tiny indie studio, all with a background in the demoscene and for about 3 years now we're developing a space planet terraforming game called SEEDS - Echoes Beneath the Sands. Our protagonist Naxiah is stranded on a small, desolated planet. You're working for an intergalactic distributor of seeds and terraforming equipment, to kickstart new planets in far away galaxies. You must deliver seeds and utilities to an unchartered region, but on your way, you crash on a small planet. Luckily, you have some equipment with you in the ship, so you're able to spawn a base and survive. But for how long? And is the planet really deserted..? :) Well, of course not, there are aliens and other space creatures. And of course, there's ROBO RB-23, which accompanies your adventure. The game is written in Object Pascal and uses our own game engine PasVulkan, our own physics engine, as well as our own RISC-V 64-bit emulator PasRISCV. We love to build stuff, a lot of these things are FOSS. The emulator is quite complete (even with RVV, but that's way too slow emulated to be useful) and runs a stock kernel (6.18.3 as of today). We're using Alpine Linux for our base distribution. All our in-game programs to interact with the planet are native RISC-V Linux programs. We also have our own (free and open source) scripting language POCA (class and prototyped based, JS/Lua inspired, which makes it quite easy for us to script things like HUD, animal behaviour, our story flow graph, etc. We have most of the wiring ready for players to be able to program and reshape and populate the whole planet in automation, although it's not our primary concept for the game (building stuff by hand, making the planet beautiful is also fun). As it's a normal Linux system, you'll be able to use Ruby, Python, or even Rust, C, C++, and Go to change and automate your world. We're also thinking of making a bunch of small games which you can play inside the game, in the base on a computer, on an arcade machine, or in the spaceship. And of course, it also runs DOOM. We already prototyped a small 2D space shooter and a small arcade game, both playable within the game. We also feature a table with hologram games to be played, e.g. chess and a certain block game. We also plan to make this hologram game engine available from the computer, which means, you'll even be able to program own hologram style games. We generally want to make the in-game computer more hackable in future, so that people can create and share their own little games. Currently, it's only a sandbox game (with beginnings of automation), to build stuff with our pre-made items. You can also assemble these to other, ready-made and shareable bigger items. This is the foundation for us to further develop survival and complete our story mode. Our game is still under active development, and we finally got our Steam page ready. We have tons of other things planned, but right now, it's more about polishing and quality for the Early Access. You can watch some videos and screenshots on our website. And we'd love to read your thoughts about his. It has been quite a ride, so far.. https://againstallodds.games/ October 2, 2026 at 04:10PM

Show HN: We built a real-time desktop companion for patient's telehealth visits https://ift.tt/2uPEGIW

Show HN: We built a real-time desktop companion for patient's telehealth visits Hey HN, Some friends and I built an app called Sidekick that joins your telehealth visits in real-time. It explains medical terms and suggests useful questions, including ones you may not have thought to ask. After the visit, it provides a summary including next steps, so you can focus on the conversation instead of taking notes. The idea of Sidekick came from our team's experiences with healthcare. Our founder, Rahul, had stage three cancer at 17. His mom had to manage everything around his care: taking notes through treatment, figuring out what questions to ask, etc. A decade later and he’s now in remission, but still sees a lot of specialists and deals with the same challenges. Another teammate became a caregiver after his dad had a severe stroke. He found himself taking notes, looking up medical terms, and trying to keep track of what was said during every doctor visit. Others have dealt with situations like this when navigating pancreatitis and other serious health issues. These experiences got us interested in how we might be able to reduce the burden on the patient or caregiver. A lot of products focus on simply recording or summarizing the visit. That's useful and a step in the right direction, but we kept coming back to the fact that a lot of the challenge originates while the conversation is still happening. If you can catch something in the moment, you can address it with your clinician immediately and potentially lead to better outcomes. If you realize you missed something after the visit, then you have to try to get another appointment (and in SF I often can't get another doctor visit till 2 months later). So we built Sidekick, to help patients and caregivers during a visit in real-time to translate medical jargon and suggest useful questions, ideally without becoming a distraction. If you want to try it, you can download it on our website. Sidekick is desktop-only for now, but we’re working on a mobile app for in-person visits. We would be especially interested to hear feedback on the live part of the experience. What are your thoughts on the balance between live help vs after-visit? Would something pre-visit be more helpful? https://openhand.health October 1, 2026 at 07:57PM

Show HN: Breadcrumb, record everything on your mac + context manager for AI https://ift.tt/iKRM4WP

Show HN: Breadcrumb, record everything on your mac + context manager for AI Hi HN, I'm Justin. Breadcrumb records everything you do on your Mac (screen + meetings + AI transcripts + what you and your AI decided) and turns it into memory your AI can search. It's local and encrypted. You can also teach it rules by talking to it and it makes sure the right rules turn up in the right context. Works with Claude Code / Codex / Cursor / opencode. All of this is exposed to your AI as 30+ MCP tools (here's the definitions): https://innerloop.works/breadcrumb/mcp I started it in June because I wanted to understand what was going on with my AI dev work. Then it just kept growing as I jammed on it 10 hours a day for 3 months. I started by recording every screen so I could jump back to a moment and see what I'd been doing with the AI. Then I added MCP so the AI could search it. Then time tracking. Then meetings with transcripts and timestamped screenshots. After that I started feeding the data back in. At first it was just a few relevant memories in the prompt. Then I started adding rules and rules modules. Then I started recording the AI transcripts and all the other stuff the AI did (subagents, tools etc). I wanted a complete record so I could go back and see what the AI did and why. I found the more data the AI had the more useful it became. One example. I got off a zoom call with the team at the day job and said: "Review the meeting I just had, find all the bugs we discussed, and create JIRA tickets with screenshots." It read the transcript. Found every bug we mentioned, pulled the screens from the screen timeline, spun up my local server, diagnosed each bug, reviewed the code, created 14 tickets in JIRA with diagnosis and likely fixes, attached 12 screenshots as evidence, and created a nice Slack message to send to my colleagues. I never built a workflow for any of that. Claude had the meeting record, Breadcrumb tools, and rules I'd accumulated. It basically chained the steps together itself. My favorite thing about the system is observability of my own work as an AI developer. I can trace a bug all the way back to the first thing I said (or the first thing the AI did) that caused it. Then I can add a rule so it doesn't happen again. Anyway, my working system is simply Claude Desktop + Breadcrumb + Markdown. I find I don't need anything else. It's local software for one person. Local models for transcription and diarization. Data encrypted with SQLCipher and a passphrase. You can exclude any apps, websites, words and phrases. Breadcrumb itself only makes one network call which is a daily update check. (but of course your AI will use it and that is local or cloud depending on what you use). It runs cool about 12% of one core on average (M series mac has 8+). You can set it to just save OCR text or to save screenshots. If just OCR it's about 12mb day (a lot of telemetry, indexing etc). If you record screenshots on meetings it's about 120mb/hour (1 every 2 secs). It can also record screenshots of everything that's heavy at about 160mb/day. It does local classification/naming with ollama with Gemma 3 4B (2.5 GB). It's 100% free. There's no account you can just download and start using it. I'll monetize it via E2EE cloud sync and team sync. It's open beta. Just one developer working on it. Requires 16GB+ M Series Mac.

Show HN: CLI and TUI control for dps150 power supply https://ift.tt/yfPUZT2

Show HN: CLI and TUI control for dps150 power supply Hey HN, Powercycling and basic power supply measurments are essential part for embedded devices development debug. But there are no interface for pwoer control for coding agents. So I created that python package which interacts with portable Fnirsi DPS-150, can toggle output, set voltage and current limits. Unexpected outcome is that it is MUCH MORE convenient to manage it in terminal and tmux than clicking on the box itself. TUI dashboard with charts, numbers and hotkeys is included. https://ift.tt/YCnGSIH October 1, 2026 at 02:01AM
