Show HN: Cave Adventure 1976 PICO-8 port Made this during COVID. I was into PICO-8 at the time and saw someone ported DOOM to it. I'm more of a text adventure guy, so I decided to port ADVENT. Basically I wrote a FORTRAN-to-Lua transpiler. The hardest part was figuring out what version of FORTRAN the source code was written in, finding a manual, cramming it into the limited cartridge space, but most of all, wrapping my mind around the data file format. Always admired Will Crowther for making this. Very fun project. I recorded myself during the whole process but I never posted a video. Future work maybe. https://ift.tt/r3Dv4AU December 31, 2024 at 10:44PM

Show HN: Handwritten Christmas Card for Hacker News Hi HN, I’ve been working on a small project that transforms handwritten notes into animated, shareable cards. While the create functionality isn’t live yet, I wanted to share a sneak peek by creating a handwritten Christmas card specifically for the HN community. I started thinking about this after seeing too many AI-generated cards, cookie-cutter email templates, and overly polished designs that lack any personal touch.

The pitch line is: "Skybear.NET is a managed platform automating Synthetic HTTP API testing." At the moment, the main source file format supported for your API tests are Hurl.dev files [1]. Hurl is a CLI tool wrapping `curl` and it's really awesome. At least check that out :) I am not affiliated directly with the Hurl CLI tool, and the platform I am building provides full Hurl compatibility.

Show HN: Convert ePUB to Audio Files A way to generate .mp3 files from ePUB. I wanted to continue "reading" even after my eyes got tired or if I went away from the screen. For these cases, what I did was select a given text, and select "Speech". If you've used this before, you know it's fine for small sections, but not for big chunks of text. So, I challenged myself to create a project that would "text-to-speech" a given book. After some attempts, I came up with a good-enough initial version using Golang. It will parse an ePUB into sections and run MacOS's `say` command to generate audio files. For now it's quite basic, but worked fine for the few files I tested. https://ift.tt/ztZQu9n December 23, 2024 at 12:15AM

After 6 years of R&D, our small team is excited to share our project TideCloak - an IAM designed to help developers move fast without worrying about catastrophic breaches or overpowered admins with keys to the kingdom. Traditional IAMs rely on centralized authority - admins, root certificates, and decryption keys - which create glaring vulnerabilities in a breach. To address this, we’ve integrated Keycloak (Red Hat’s IAM) with a decentralized key architecture powered by our (academically validated) Ineffable Cryptography. Here’s the idea: keys are split across a decentralized network (our Cybersecurity Fabric) so no one ever holds the full key. Even in a breach or F$%k up, there’s no unchecked authority exposed. Right now, TideCloak uses the Cybersecurity Fabric as an IdP, meaning users authenticate without their credentials being stored or shared. Essentially, users bring their own authority - without...

I work as an Android developer at a large retailer, on the app that the in-store employees use to see their schedules, view product details, get support, etc. Part of our engineering on-call rotation involves helping these in-store employees with any app issues they may encounter. There are always a few times every rotation where I know solving someone's problem would be way easier if I could just see their screen as if I were in-store with them. However, many of these employees are non-technical and wouldn't want to go through the onboarding of TeamViewer or Zoom, are under time constraints in a busy store, or (understandably) just wouldn't know how to get set up.

These features are designed to make it easier for people to trust and use these servers in production environments.

Show HN: Autonomous AI agents that monitor the stock market for you We created autonomous AI Agents that monitor the stock market for you while you go about your day. How it works: Tell our AI Assistant what you want to monitor, and it creates a project for our team of autonomous AI Agents. You'll get notifications (email + app) when significant events matching your criteria are detected. For short-term projects, you'll be notified when your analysis is ready. Behind the scenes: When you give the AI Assistant a request to monitor an entity (like a stock or group of stocks), an AI Project Manager plans the project and breaks the project down into manageable tasks. These tasks run asynchronously - some recurring (hourly/daily/weekly/monthly/quarterly/yearly), others one-time. Example prompts you can try: Long-term monitoring: - "Monitor Apple stock and notify me of any important events and red flags" - "Monitor Apple, Google, Microsoft, and Meta stock. Notify me if...

Show HN: NCompass Technologies – yet another AI Inference API, but hear us out Hello HackerNews! I’m excited to share what we’ve been working on at nCompass Technologies: an AI inference platform that gives you a scalable and reliable API to access any open-source AI model — with no rate limits. We don't have rate limits as optimizations we made to our AI model serving software enable us to support a high number of concurrent requests without degrading quality of service for you as a user. If you’re thinking, well aren’t there a bunch of these already? So were we when we started nCompass. When using other APIs, we found that they weren’t reliable enough to be able to use open source models in production environments. To resolve this, we're building an AI inference engine that enable you, as an end user, to reliably use open source models in production. Underlying this API, we’re building optimizations at the hosting, scheduling and kernel levels with the single goal of minimizi...

Show HN: I made the slowest, most expensive GPT This is another one of my automate-my-life projects - I'm constantly asking the same question to different AIs since there's always the hope of getting a better answer somewhere else. Maybe ChatGPT's answer is too short, so I ask Perplexity. But I realize that's hallucinated, so I try Gemini. That answer sounds right, but I cross-reference with Claude just to make sure. This doesn't really apply to math/coding (where o1 or Gemini can probably one-shot an excellent response), but more to online search, where information is more fluid and there's no "right" search engine + text restructuring + model combination every time. Even o1 doesn't have online search, so it's obviously a hard problem to solve. An example is something like "best ski resorts in the US", which will get a different response from every GPT, but most of their rankings won't reflect actual skiers' consensus - say, ...

Show HN: TTS Accents – 1000 voice combinations Most TTS models today have a fixed set of voices that are tied to a fixed set of languages. We built a trained TTS model with the concept of accents like we have in real life. You can have a Chinese person speaking English or a German person speaking French. Hints of their accents from their original language can be heard when they speak another language. We took this idea and the understanding of how one-shot voice cloning works and trained a model on 100+ voices & languages, giving you 1000+ unique voice combinations. One interesting use case is customer support to have a voice sound similar to where the person is calling from, making them feel more at home! It's still pretty new, and there's more to come, but we do have users using it in production, open to any feedback and ideas :) Try it for free: https://ift.tt/rboDpnU https://ift.tt/rboDpnU December 12, 2024 at 11:28PM

Show HN: Ucacher, Caching via Syscall Instrumentation Hi! I would like to share something really cool we've just created at Earthly. It's a tool that makes caching and skipping in GitHub Actions smarter and easier. While we started it as a project to increase CI/CD speed for enterprise users, focusing on easy of adoption, soon we realized that enterprises don't care about CI/CD speed as much as we were expecting. So decided to integrate it natively with GitHub Actions cache API and share it with the community, so at least developers can benefit from it. Honestly, we're not sure how its future will unfold, it will likely evolve based on the feedback we receive. https://ift.tt/BnTgXcr December 12, 2024 at 08:04PM

Show HN: White Ninja – Conversational AI agent for prompt engineering I built a free tool that approaches prompt engineering differently. Instead of writing prompts manually, you interact with an AI agent that: 1. Understands your intent through conversation 2. Generates optimized prompts based on your requirements 3. Battle-tests prompts against common failure modes 4. Iteratively improves based on test results Technical details: - No registration required - Built-in testing framework - Handles context window management - Implements safety guardrails automatically The motivation came from observing that manual prompt writing is error-prone and time-consuming. The agent helps bridge the gap between intent and implementation.

Show HN: Pointer – The first AI agent for Google Docs that doesn't chat with you Hi HN, I'm Rade, the developer behind Pointer — the first AI agent for Google Docs. Have you ever tried copying text from ChatGPT into Google Docs and ended up with a formatting mess? I certainly have, and it was frustrating. The constant fixing of styles and formatting broke my workflow and wasted time. That's why I built Pointer. Instead of juggling between ChatGPT and Google Docs, you can now give instructions right within your document. Pointer acts on your requests by typing out changes in real-time and adds comments explaining the reasoning behind each suggestion. You can approve or reject these changes as you see fit. One of the technical challenges was creating a seamless experience that feels native to Google Docs. Under the hood, Pointer communicates with the OpenAI API to process your instructions and generate context-aware edits without disrupting your writing flow. By eliminating t...

We’re now exploring new features, including enhanced notifications, advanced configuration options, DNS monitoring, and status pages (which are almost ready to launch btw). There are no plans for synthetic monitoring, APM, log management, traces etc. It'll hopefully stay as small as possible. It's still the early days for Checkmate.

Show HN: Banan-OS, an Unix-like operating system written from scratch This is my operating system that I've been working for the past 2 years. All of the code is written exclusively by me except from ported software. banan-os has a monolithic kernel targeting x86 (i686) and x86_64 architectures. The project consists of bootloader, kernel and userspace libraries (libc, libGUI, libFont, ...). It also uses my custom C++ standard library partly based on stdc++. Currently I have basic TTY and GUI environment with some of the basic UNIX utilities like cp, ls and stat. I have basic support for USB (keyboard/mouse/storage), disks (NVMe, AHCI), custom networking stack with TCP and UDP support, and a UNIX-like filesystem with /dev /tmp /proc filesystems. The whole project is written in C++ except for my BIOS bootloader that is written in 16-bit real mode assembly. I have been testing the OS mainly on virtual machines but also frequently on real hardware. https://ift.tt/tBIsNkD December 6, 20...

I’ve tried every transcription and meeting tool out there, and none of them worked the way I needed. So, I built Amurex: - No clunky bots joining or announcing themselves. - Accurate, clean transcripts delivered right after the meeting. - Auto-generated follow-ups that I can edit and send in seconds. But most importantly, it is the only meeting copilot that does: - Real-time suggestions during meetings to help me stay focused (or at least less miserable). It’s also fully open source because I believe good tools shouldn’t be locked behind paywalls. If you’ve ever struggled to stay engaged in meetings or needed quick, reliable transcripts and follow-ups.

Runs on lots of things (including OpenWrt APs, Macs, Linux containers) * Typescript/React client, with protobuf based signalling, works with Chrome, Firefox and Safari * "Backhaul" means SFUs can act as clients to other SFUs, and then forward everything they receive * Reasonably stable, including as you start/stop/start/stop backhauls and participants come and go repeatedly This is very early days, but you can have four 720P participants on a D-Link AX3200 access point, and it will only use about 25% of the CPU.
