Show HN: Blacklight – secret scanner for code, databases, drives, and slack https://ift.tt/uVbjzCQ

Show HN: Blacklight – secret scanner for code, databases, drives, and slack We often ran pattern matching searches for secrets and keys across codebases, databases etc. Therefore, we thought about converting that workflow into a tool that we could just easily generate a SARIF report and share with our customers. Blacklight is a powerful secret, key, and sensitive data scanning tool that helps you detect and prevent sensitive information leaks in your codebase, databases, cloud storage, and communication platforms. The idea is that one can add their custom rules around their governance and compliance requirements. The platform comes with 114 matching criteria, but this can be extended easily. https://ift.tt/MwEkdSv May 18, 2025 at 12:10AM

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless https://ift.tt/5YLNSlR

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless Hey everyone! Over the past two years I threw myself back into full-time engineering with a simple goal: write code that gives back to the community. After a lot of late-night FOMO (“AI will do it all for us, right?”) and some painful production incidents, I finally turned my weekend project into an open-source library. [ What is Solidis ? ] - Super-light (< 30 KB) RESP2/RESP3 client with zero runtime deps and first-class ESM/CJS support. - Fully tree-shakable – import only the commands you need. - Written with SOLID principles & full TypeScript typings for every command. - Designed for cold-start sensitive serverless platforms (small bundle + tiny memory footprint). [ Why I built it ] 1. node-redis & ioredis pain - ESM is still an after-thought. - Hidden deadlocks on RST, vague error surfaces. - Everything gets bundled, even commands you’ll never call. 2. I refuse to add a dependency I don’t fully understand – I literally read candidates 10× before `npm i`. 3. Serverless bills love to remind me that every KB and millisecond matters. [ Key features ] - Protocols: RESP2 and RESP3 (auto-negotiation) - Bundle size: `<30 KB` (core) / `<105 KB` (full) - Dependencies: 0 - Extensibility: Drop-in command plugins, custom transactions - Reliability: Auto-reconnect, per-command timeouts, type-checked replies [ Roadmap / Help wanted ] - Benchmarks against `node-redis` & `ioredis` (PRs welcome!) - More first-class Valkey love - Fuzz-testing the parser - Docs site – the README came first; I’d love help polishing full docs This might be my last big OSS push for a while, so stars, issues, and PRs mean the world . If Solidis saves you some cold-start time or just scratches a TypeScript itch, let me know! Repo: https://github.com/vcms-io/solidis License: MIT Thanks for reading, and happy hacking!

Show HN: KVSplit – Run 2-3× longer contexts on Apple Silicon https://ift.tt/PB0N7IV

Show HN: KVSplit – Run 2-3× longer contexts on Apple Silicon I discovered that in LLM inference, keys and values in the KV cache have very different quantization sensitivities. Keys need higher precision than values to maintain quality. I patched llama.cpp to enable different bit-widths for keys vs. values on Apple Silicon. The results are surprising: - K8V4 (8-bit keys, 4-bit values): 59% memory reduction with only 0.86% perplexity loss - K4V8 (4-bit keys, 8-bit values): 59% memory reduction but 6.06% perplexity loss - The configurations use the same number of bits, but K8V4 is 7× better for quality This means you can run LLMs with 2-3× longer context on the same Mac. Memory usage scales with sequence length, so savings compound as context grows. Implementation was straightforward: 1. Added --kvq-key and --kvq-val flags to llama.cpp 2. Applied existing quantization logic separately to K and V tensors 3. Validated with perplexity metrics across context lengths 4. Used Metal for acceleration (with -mlong-calls flag to avoid vectorization issues) Benchmarked on an M4 MacBook Pro running TinyLlama with 8K context windows. Compatible with Metal/MPS and optimized for Apple Silicon. GitHub: https://ift.tt/mxNnqv6 https://ift.tt/mxNnqv6 May 17, 2025 at 01:34AM

Show HN: Easel – Code multiplayer games like singleplayer https://ift.tt/LsRBc6N

Show HN: Easel – Code multiplayer games like singleplayer For the past 3 years, I've been creating a new 2D game programming language where the multiplayer is completely automatic. The idea is that someone who doesn't even know what a "remote procedure call" is can make a multiplayer game by just setting `maxHumanPlayers=5` and it "just works". The trick is the whole game simulation, including all the concurrent threads, can be executed deterministically and snapshotted for rollback netcode. Normally when coding multiplayer you have to worry about following "the rules of multiplayer" like avoiding non-determinism, or not modifying entities your client has no authority over, but all that is just way too hard for someone who just wants to get straight into making games. So my idea was that if we put multiplayer into the fabric of the programming language, below all of your code, we can make the entire language multiplayer-safe. In Easel the entire world is hermetically sealed - there is nothing you can do to break multiplayer, which means it suits someone who just wants to make games and not learn all about networking. I've had people make multiplayer games on their first day of coding with Easel because you basically cannot go wrong. There were so many other interesting things that went into this project. It's written in Rust and compiled to WebAssembly because I think that the zero-download nature of the web is a better way of getting many people together into multiplayer games. The networking is done by relaying peer-to-peer connections through Cloudflare Calls, which means Cloudflare collates the messages and reduces the bandwidth requirements for the clients so games can have more players. I also took inspiration from my experience React when creating this language, here's how you would make a ship change color from green to red as it loses health: `with Health { ImageSprite(@ship.svg, color=(Health / MaxHealth).BlendHue(#ff6600, #66ff00)) }` There is a lot of hidden magic that makes the code snippet above work - it creates a async coroutine that loops each time Health sends a signal, and the ImageSprite has an implicit ID assigned by the compiler so it knows which one to update each time around the loop. All of this lets you work at a higher level of abstraction and, in my opinion, make code that is easier to understand. Speaking of async coroutines, my belief is that they don't get used enough in other game engines because their lifetimes are not tied to anything - you have this danger where they can outlive their entities and crash your game. In Easel each async task lives and dies with its entity, which is why we call them behaviors. Clear lifetime semantics makes it safe to use async tasks everywhere in Easel, which is why Easel games often consist of thousands of concurrently-executing behaviors. In my opinion, this untangles your code and makes it easier to understand. That's just the beginning, there is even more to talk about, it has been a long journey these past 3 years, but I will stop there for now! I hope that, even for those people who don't care about the multiplayer capabilities of Easel, they just find it an interesting proposal of how a next-generation game programming language could work. The Editor runs in your web browser and is free to play around with, so I would love to see more people try out making some games!

Show HN: AsianMOM – WebGPU Vision-LLM app that roasts you like ur mom in-browser Randomly got inspired yesterday seeing SmolVLM working on WebGPU and had the silly idea for this project. it's not perfect and super limited because of the current limitations of WebML (and admittedly, because I suck at prompting, but that's why it's Open Source haha) but it is 1.5B WORTH OF AI (SmolVLM 500M and LLama 3.2 1B) working RIGHT IN YOUR BROWSER with you not having to install anything! In fact, the whole thing is actually just an index.html that you can install and even use directly! It might be a little bit slow on first try (takes about 3 mins) when it installs models, but it caches it so it's way faster the second time (also, it's available offline after it's cached haha) Works on any modern web browser It may be a funny little project, but it's genuinely taught me so much about WebML and Vision models, and the technologies we're getting with WebML will 100% democratize AI access and make it way simpler and easier to be used everywhere :p GH Repo in case you're interested: https://ift.tt/EtCJRj7 https://ift.tt/dJMCkVe May 16, 2025 at 12:50AM

Show HN: Family Folder – Help your family remember everything, organise anything https://ift.tt/Zx9MyL8

Show HN: Family Folder – Help your family remember everything, organise anything Hi Show HN, I’m both nervous and excited to share what I’ve been working on in the early mornings and late evenings over the past few months: Family Folder – a tool to help you and your loved ones stay connected, simplify planning, and never miss a moment. This is mostly a solo project—though I’ve leaned on ChatGPT and Upwork when I hit the limits of my technical skills. I love learning, and this has been a crash course in programming, DevOps, design, UX, and everything in between. The idea came directly from my own experience: trying to keep on top of family life, from newborns to supporting my mum’s memory, birthdays, childcare logistics, and where the insurance documents are stored. Existing tools felt too generic, too corporate, or too messy. I wanted something built for families. Stack: • Ruby on Rails 7 (via Jumpstart Pro) • PostgreSQL • Hosted on Heroku (EU region) • S3 (EU) for file uploads • (Coming soon: iOS app & AI assistant) Family Folder is private by design—you only see what you’re invited to. It’s meant to be simple enough for parents or siblings to actually use, but structured enough to avoid chaos. If this sounds useful—or if you’ve ever tried to manage a family using group chats or shared docs—I’d love your feedback. What would make something like this truly work for your family? Thanks for taking a look! – Tony https://ift.tt/5kLzE7x https://ift.tt/5kLzE7x May 15, 2025 at 12:27AM

It is a tool for working with Git repositories, more specifically, extracting and calculating current/upcoming semantic versions for your repo's tags. It is heavily inspired by the output from "git describe --tags". Why use anything else then? The output is not fully SemVer compliant and therefore I was modifying it in all my projects separately, which I wanted to avoid. Single binary, single predictable output. It does not currently have pre-built binaries, so you have to install it via cargo, but it's in the roadmap! https://ift.tt/2SjaEce May 14, 2025 at 08:40PM

Show HN: Open-source AI code review agent that's aware of your entire codebase https://ift.tt/n8mwx4E

Show HN: Open-source AI code review agent that's aware of your entire codebase Hey HN! I'm one of the cofounders of Sourcebot, an open source alternative to Sourcegraph. Sourcebot lets you index thousands of repos across multiple platforms (GitHub, GitLab, Bitbucket), and gives you a powerful interface to search across them. You can learn more in our original HN launch post: https://ift.tt/wuvRk9j We just added an AI code review agent that reviews your PRs and automatically detects issues that a human reviewer may have missed. We've been using an AI code review agent for a few weeks now, and it regularly catches issues that we would've merged to prod. The review agent automatically fetches relevant context from code you've indexed in Sourcebot to provide accurate reviews. We’ve found that fetching this context is critical for the LLM to provide meaningful suggestions. Would love any feedback if y'all get the chance to try it out! We're planning on expanding the context fetching capabilities to support: - Fetching definitions from function calls in a code snippet - Fetching all usages of a function across all your repos to ensure proper usage patterns - Any other code context fetching y'all think would be useful!

Show HN: Miralis – a RISC-V virtual firmware monitor https://ift.tt/LJFCwoI

Show HN: Miralis – a RISC-V virtual firmware monitor Miralis is a RISC-V firmware that virtualizes RISC-V firmware. In other words, it runs firmware in user-space (M-mode software in U-mode). The fact that this is even possible is interesting: indeed, not all ISAs are virtualizable, and the same applies for their firmware mode. It all boils down to the virtualization requirements [1], which is a great read if you haven't come across it yet. Arm's EL3 cannot be virtualized, for instance, because some instructions, such as `cpsid`, are sensitive but do not trap (`cpsid` is a nop in user-space). If you have a VisionFive 2 or a HiFive Premier P550, you can try it out, the instructions are in the documentation [2, 3]. Of course, it runs on QEMU too. As Miralis is a research project, we have also been using it as a vehicle to explore other research ideas, such as automated verification of hypervisors [4]. For instance, we verified instruction emulation by comparing Miralis' implementation with the reference RISC-V executable specification [5], which we translated to Rust. It has been fun working on Miralis, I hope you'll find it interesting too! [1]: https://ift.tt/A2CUN1H [2]: https://ift.tt/gJKr5R3... [3]: https://ift.tt/TfoysHa... [4]: https://ift.tt/9TsDcS8...

Show HN: Limits.fyi – See what you are getting out of all your AI subscriptions https://ift.tt/SiQEaWm

Show HN: Limits.fyi – See what you are getting out of all your AI subscriptions Hey HN, I've personally been having a hard time keeping track of all the changes to AI subscriptions these days. Sama is always tweeting about ChatGPT usage limits being improved as they add more GPUs, nobody knows how many Claude messages you get in a day, and Windsurf just recently updated their pricing plan. It's becoming increasingly difficult to get a clear and transparent view of what you're actually getting with each subscription. This becomes especially frustrating when you run into those annoying “no more remaining message” popups right in the middle of a coding session. I've also noticed many developers suffer from what I've started calling "query anxiety”, this is when a person is always worried about hitting their usage limits, so they just end up not using these models when they actually need them. That's why I created limits.fyi which lets you view and compare usage limits for all the popular AI subscriptions in one place. You can: - See exactly what usage limits come with each plan - Filter by specific models to find which subscriptions give you access - Compare prices to find the best value for your needs - Discover new services you might not have known about I try and keep the data up-to-date, and welcome user submissions. If you notice changes or have new information, you are encouraged to contribute using the submission feature at the bottom of the page. Check it out here: https://www.limits.fyi/ I'd love to hear your thoughts and suggestions on how to make this more useful. https://www.limits.fyi/ May 9, 2025 at 12:08AM

Show HN: Cloi – free local debugging agent in your terminal https://ift.tt/sVI3aq9

Show HN: Cloi – free local debugging agent in your terminal Hey everyone! For the past two weeks my friend and I have been heads-down building Cloi, a fully local debugging agent that runs right in your terminal. You probably know the drill—every AI coding tool asks for API keys, subscriptions, and uploads your entire codebase to the cloud. Cloi does none of that: it runs entirely on your machine, with no cloud, no API keys, no subscriptions, and zero data leaving your system. What Cloi does: - Contextual error capture: Grabs your stack trace, local files, and environment to understand the issue. - Local LLM inference: Spins up Ollama on your box and generates targeted fixes—no external servers. - Safe patch application: Presents you with diffs and only applies changes when you explicitly approve. - Model‐agnostic: Ships with Phi-4 out of the box (surprisingly capable for its size!), but you can swap in any Ollama model you’ve installed. Why we built it: - Maintain full control over your code and data—ideal for security-sensitive projects - Avoid recurring subscription fees and cloud vendor lock-in - Keep your development flow entirely offline when you need it Highlights: We hit 202 stars in just 5 days, which tells us we're not the only ones who wanted this! Cloi is plug-and-play (just install and run), and we designed it to be completely unopinionated, meaning you can you whatever Ollama model you want. Get it now: npm install -g @cloi-ai/cloi If you find Cloi useful, we’d really appreciate a star on GitHub.

Show HN: Kevin-32B – how to do multi-turn RL on writing CUDA kernels Hey – we just published a blog post about Kevin-32B = K(ernel D)evin. It's to our knowledge the first open-source model that's RL-trained on CUDA kernels. Our goal was to demonstrate multi-turn RL using GRPO. We used 180 Python->CUDA conversion tasks from the KernelBench dataset. The results were surprisingly strong! We were able to outperform top reasoning model like o3 & o4-mini. We're sharing our training setup and learnings in the blogpost. Also the model is on HuggingFace: https://ift.tt/0yh2O8l https://ift.tt/CD7O8up May 7, 2025 at 01:18AM

Show HN: X402 – an open standard for internet native payments https://ift.tt/WPYswBU

Show HN: X402 – an open standard for internet native payments Hi HN – excited to announce x402, initially developed by Coinbase (YC 12) x402 lets any HTTP API charge per request without issuing API keys or storing credit cards. Buyers (humans or AI agents) keep funds in their own wallet and dynamically discover compatible endpoints, call them as usual, and automatically pay a microtransaction in USDC or other tokens to settle. 90 second demo: https://www.youtube.com/watch?v=PV-L2AfLhJg Problem: Every time we want to use a new API we have to: find the service online create a developer account, copy a secret key into env vars, pre-fund or hand over a credit card This flow blocks agents even more. They can’t solve CAPTCHAs or enter credit cards. It also hurts sellers: fraud, chargebacks, onboarding friction, and marketing to humans are huge pain points. Why buyers care Zero setup – Hit a new endpoint immediately. Runtime discovery – Because every x402 service exists in a common registry, an agent can search, compare, and invoke in one loop. Self-assembling agents become practical. Easily create proxy servers – Want an endpoint that isn’t supported? You can use our proxy server template to spin up an x402-compatible instance yourself using traditional API keys, and monetize it for others wanting access. Why sellers care Reach incremental demand – Long-tail bots, side projects, one-off scripts, all of which too small for an account/signup flow, can now pay you. Micropayments without fraud – All payments settle onchain, nothing for stolen credit cards or chargebacks to reverse. Embedded distribution – instead of marketing to humans, create a compelling service meeting demand for agents and watch the requests roll in. How we got here Last year we launched AgentKit (wallets for AI agents). Tens of thousands of agents now hold onchain balances, but they can’t pay for most web services. We revived the long-unused HTTP 402 (“Payment Required”) status code and wrote a spec to make it real. Marc Andresseen calls the lack of native value transfer “the original sin of the internet,” and we see x402 as the absolution of this sin. How it works: x402 specifies a standard response body to accompany a 402 status code. This response body contains machine understandable instructions for how to pay. Payments are signature based an included as an `X-PAYMENT` header in a subsequent request to the same API endpoint. The accepting server can verify and settle payment themselves, or delegate the onchain settlement to what we call a facilitator. This means you don't have to touch crypto as a developer, you can just integrate a middleware and start receiving stablecoin payments in as little as 1 line of code. Because x402 natively traverses your existing client / server requests, it can be implemented in any language, and doesn't require webhooks, or any other complex integration. Its literally this simple: `paymentMiddleware("0xYourAddress", {"/your-endpoint": "$0.01"})` Ask HN API providers – does the one-line integration fit your stack? What’s missing? Agent / infra builders – if a service isn’t available is the proxy server template sufficient? File issues, PRs welcome Everyone – poke holes in the trust and fee model; we’d love to iterate with your feedback Curious to learn more?

Show HN: Feedsmith — Fast parser & generator for RSS, Atom, OPML feed namespaces https://ift.tt/MSugYps

Show HN: Feedsmith — Fast parser & generator for RSS, Atom, OPML feed namespaces Hi HN! While working on a project that involves frequently parsing a lot of feeds, I needed a fast JavaScript-based parser to extract specific fields from feed namespaces. Existing Node packages were either too slow or merged all feed formats, losing namespace information. So I decided to write it myself and created this NPM package with a simple API. Feedsmith supports all feed formats and many popular namespaces, including: Podcast, Media, iTunes, Dublin Core, and more. It can also parse and generate OPML files. I am currently adding support for more namespaces and feed generation for RSS, Atom and RDF. The library grew into something bigger than I initially anticipated, so I also started creating a dedicated documentation website to describe all the features. https://ift.tt/VhH3pCK May 6, 2025 at 11:33PM

Show HN: Tired of bloated time trackers? Here's a dead-simple, free one I built https://ift.tt/b2mziKP

Show HN: Tired of bloated time trackers? Here's a dead-simple, free one I built Hey HN! I made TimeAnt because my dad needed a simple way to track his time at work and he didn’t like the other apps out there because they were too complicated or had way too many features. So, I built an app that just does the basics: track work hours, meetings, breaks, lunch and optionally lets you add notes - and that's it. It’s totally free, works both online and offline, and doesn’t require an account (but you can create one if you want). The goal was to keep it super simple and let you focus on tracking time without all the fluff. It also gave me a chance to learn Swift and build my first native iOS app! I’d love to hear what you think! Best, Viktor https://ift.tt/zGTAf9r May 6, 2025 at 01:21AM

Show HN: I built a mini macOS app to reveal my yearly subscription spending https://ift.tt/cM9kYmQ

Show HN: I built a mini macOS app to reveal my yearly subscription spending I built a macOS app to track my subscriptions after realizing I was spending over $XXXX annually on services I barely used. I wanted a simple, privacy-focused tool to help me stay on top of recurring charges without relying on third-party integrations or sharing financial data. Key Features: – Visual Calendar: See all upcoming charges in a monthly view. – Custom Notifications: Set reminders for upcoming payments. – Highlights: Flag subscriptions as annual, trial, or one-time. – Statistics: View projected yearly spending, average monthly costs, and peak spending months. – Custom Categories: Organize subscriptions with user-defined categories. – Multi-Currency Support: Convert prices on the fly to your preferred currency. – Status Management: Mark subscriptions as active or canceled, with accurate updates in your stats. – Quick Addition: Start typing a service name, and the app auto-suggests logos, categories, and colors. – Import and export data The app is free to use with some limitations. I’m currently working on additional features and would appreciate any feedback or suggestions from the community. https://ift.tt/fynLk7H May 5, 2025 at 11:31PM

Show HN: I made a knife steel comparison tool https://ift.tt/NBgl0Hc

Show HN: I made a knife steel comparison tool Hi HN, I’ve been collecting pocket‑knives for years, but every time someone asked “Is 20CV better than S45VN for corrosion?” I ended up hunting through scattered steel charts and forum posts. Last month I finally built a single‑page Knife Steel Explorer to scratch that itch. What it is – A no‑login web app where you can filter 49 steels by corrosion resistance, toughness, edge retention, and ease of sharpening, then compare the ones you select in radar, bar, or scatter plots. Why it’s different – Side‑by‑side data comes from peer‑reviewed metallurgy papers and CATRA tests and consensus as discussed from enthusiast websites, normalized to a 0‑10 scale so you can weigh trade‑offs visually instead of parsing spreadsheets. How it’s built – React + TypeScript + D3 for the charts, all static files on Vercel with a simple express / Typscript backend, so it should survive an HN hug‑of‑death. Try it – https://ift.tt/gH9SUt0 (loads instantly, no signup, no tracking). I’d love feedback on: Is the 0‑10 scale intuitive or would you prefer raw units (HRC, g/mm, etc.) in the main view? What extra filters or metadata (price, country of origin, typical hardness range) would help your own knife buying or designing? Any UI rough edges that stop you from exploring quickly? Thanks for taking a look—happy to answer anything about the data set or implementation! https://ift.tt/gH9SUt0 May 4, 2025 at 10:13PM

Show HN: Open-lmake, a scalable, reliable build system with auto dep-tracking https://ift.tt/ul7TiA3

Show HN: Open-lmake, a scalable, reliable build system with auto dep-tracking Hello Hacker News, I often hear people saying "all build-systems suck", an opinion I have been sharing for years, and this is the motivation for this project. I finally got the opportunity to make it open-source, and here it is. In a few words, it is like make, except it can be comfortably used even in big projects using HPC (with millions of jobs, thousands of them running in parallel). The major differences are that: - dependencies are automatically tracked (no need to call gcc -M and the like, no need to be tailored to any specific tool, it just works) by spying disk activity - it is reliable : any modification is tracked, whether it is in sources, included files, rule recipe, ... - it implements early cut-off, i.e. it tracks checksums, not dates - it is fully traceable (you can navigate in the dependency DAG, get explanations for decisions, etc.) And it is very light weight. Configuration (Makefile) is written in Python and rules are regexpr based (a generalization of make's pattern rules). And many more features to make it usable even in awkward cases as is common when using, e.g., EDA tools. Give it a try and enjoy :-) https://ift.tt/jh4lJ7S May 3, 2025 at 09:41PM

Show HN: I built a synthesizer based on 3D physics and launched the product https://ift.tt/9BAjRr7

Show HN: I built a synthesizer based on 3D physics and launched the product I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with (awesome) contractors brought in for some of the stuff that I'm bad at, like the 3D models and making instrument presets/videos. The official launch announcement video is here: https://www.youtube.com/watch?v=NYX_eeNVIEU But if you REALLY want to see what it can do, check out what Mick Cormick did with in on the first day: https://ift.tt/RVyvBXG I've kept a fairly detailed developer log about my progress on the project since October 2023, which might be of interest to the hardcore technical folks here: https://ift.tt/KgCZkEw I also gave a talk at Audio Developer Conference 2023 (ADC23) that goes deep into a couple of the problems I solved for Anukari: https://www.youtube.com/watch?v=lb8b1SYy73Q https://anukari.com May 2, 2025 at 11:42PM

Show HN: Lichen – Manage and create code licenses on the CLI and with TOML https://ift.tt/d3faXl5

Show HN: Lichen – Manage and create code licenses on the CLI and with TOML Hey! I'm Miles, I built this tool to be a fast and reliable solution for generating licenses on the CLI. Licensing has always been a point of stress for me, with how much is at stake. If I copy one from the wrong website, the version I download is the wrong one, or any number of mishaps, my whole code is at risk. We see this fiasco play out all the time. We shake our saddened heads and go on. No longer! Lichen is designed to generate licenses sensibly with three words on the CLI. `lic gen MIT`. Or in a `.lichen.toml` in your project root. Add authors/maintainers with --authors, date it with --date, license specific parts with exclude patterns and double licenses. Project big or small, it's got everything (I think). (Tell me what it's missing please). It uses SPDX licenses for correctness. Written in Rust, you'll know you're safe, and if you want to be extra cautious, feel free to create license headers on all your files (Fast too! Can do this for the entire cargo project in 22s uncached). I'm happy to answer any questions/concerns/whatever about my tool, it's my biggest project to date (And therefore my most bug-ridden...) https://ift.tt/pQH1CvP May 1, 2025 at 10:25PM

Show HN: Robot Unlock – an open-ended programming game/zachlike https://ift.tt/bXCm0AO

Show HN: Robot Unlock – an open-ended programming game/zachlike Hello, In 2010 I made an open-ended programming game based on Befunge and Brainf*k. I was young and didn't know what I was doing - coding it in AutoIT of all things and using borderless windows for sprites. Nevertheless, it was a full game and some people actually played it, sharing solutions with each other. I took it as a sign that the game had some potential - I appreciated this very much at the time. It was zachlike at its core, except that it came out earlier than SpaceChem and the term hadn't been coined yet. Years passed, I worked in the game industry, had some fun, learned a few things and eventually burned out. Meanwhile, Zachtronics kept making games and managed to define a genre, proving that there indeed was a market for such games. I'm very happy about that. Now I want to have a shot at going indie and almost 15 years later I'm launching the sequel to my 2010 game. One of my playtesters has been at it for 26 hours so I know it can be a real nerd sniper. It's a game for the type of person who loves quirky languages and optimizing their programs under extreme constraints. I have been hanging out on HN for a long time and thought some in this community might like the game. I want to keep doing this and I will as long as I can afford it. Looking forward to your questions and feedback. https://ift.tt/5OS74Wc https://ift.tt/ZE1XiLu May 1, 2025 at 09:08PM
