Show HN: Cave Adventure 1976 PICO-8 port https://ift.tt/gHzaOdI

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/6Ac4vrY December 31, 2024 at 10:44PM

Show HN: A search engine that values depth over popularity Hey HN, I'm excited to introduce Graphthem, a search engine designed to explore the deeper layers of knowledge rather than just surface-level popularity. While many AI search engines simply summarize top N results, we've found this approach often misses the many good stuff that is buried deeper in the links and references. Graphthem takes a different approach. we don't just look at the first few pages we find. We also dig into what those pages link to, so you get the whole story. This allows us to deliver answers that capture not just what's immediately visible, but also the foundational ideas and deeper insights that inform those results. Here's a comparison between Perplexity and Graphthem: Query 1: "most watched youtube videos?" Perplexity: https://ift.tt/bS7vnlD... Graphthem: https://ift.tt/n9YM3OZ... - Query 2: "what is pagerank?"

Show HN: We build drones that pick items in e-commerce fulfillment centers At Hummingbird Systems, we have developed a unique drone based approach to robotic warehouse unit order picking, especially well suited to direct-to-consumer e-commerce fulfillment. So why use drones? … Fundamentally lower cost. Hummingbird's drone platform is inherently less expensive than ground robots with pick arms or large gantry style AS/RS systems. The drones allow us to directly position the manipulator on task without all the weight and expense of multi-axis backlash free geared motor assemblies. Furthermore unlocking the often unused vertical real-estate in e-comm warehouses, the ability to leverage existing bins and racking, and a unique overhead tether power system that eliminates the need for batteries or recharging all contribute to the best ROI of any robotic picking solution on the market.

Show HN: Skybear.net – A managed platform automating Synthetic HTTP API testing https://ift.tt/57doHPB

Show HN: Skybear.net – A managed platform automating Synthetic HTTP API testing Hey folks, I am finally posting a Show HN post for a project I have been working on for several months now, and it's in a state where I already get a lot of value myself, so I am happy to share broadly. 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. I have been using Hurl for a few years now [2], and use it for my API testing, for orchestrating a bunch of HTTP APIs, and in general whenever I need to do anything with HTTP requests, I reach for Hurl. You can try without signup the basic execution feature with the free Open Editor [3], but for full functionality (retaining responses and cron triggers) you need a signed in account, even free. The Skybear.NET platform: 1. Has Hurl Compatibility, so take your local scripts and run them on the cloud as well. No changes needed. 2. Provides managed infrastructure for authoring, storing, and most importantly executing your Hurl scripts, that automatically scales to handle as many script runs as you need. 3. Generates detailed reports from your tests execution, automatically persisting requests and response bodies for introspection in the future, and with automatic insights coming up soon. 4. Supports multiple ways of triggering execution of your scripts, including periodic executions, and on-demand HTTP triggers enabling integration with your CICD pipelines. Most importantly, it eliminates excessive per-request/per-step/per-check charges, leading to substantial cost-savings for complex multi-step API tests covering complete user-journeys. I consider a "script project run" to be the main unit in my pricing, which includes execution of all the source files of the script project, which can be tens or hundreds of requests. I am starting to document some of the architecture of the platform as well [4], but in a nutshell, all your data is encrypted inside the application before stored on AWS (S3, DynamoDB, also encrypting at rest) [5], the control plane runs on Hetzner and AWS EC2, and the execution servers running your scripts run on Fly and soon on AWS EC2 (for some plans). Future plans depend a lot on feedback from users. I already have a long list of things I personally want to have, but as more users start using I would like to see user needs influencing the roadmap more. Some upcoming features: 1. Insights and metric graphs for historical tracking of your tests (per project, per file, per request URL). 2. Automatic generation of tests based on OpenAPI schemas, HAR files, etc. 3. Export API of all the data and reports for your own consumption. 4. OTEL traces generated per script run, exportable and sent to APM products. Thank you, and I hope you find it interesting too!

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/cxK52N4 December 23, 2024 at 12:15AM

Show HN: Get e-signatures & pay per signed doc Woke up today with a 100-degree fever & found out Google is now our competitor. Last week, we started building signwith.co/ - a simple, pay-per-use e-signature tool for people who are struggling with complex e-sign tools. The plan was to build quietly, run a private beta, get 50 users in 15 days, and then do a launch. Easy peasy. But since Google dropped into the e-signature space - we needed to talk. So after 30 minutes of existential dread, a lot of “what are we even doing?” thoughts, and one strong dose of paracetamol we said, screw it. - let’s change gears. So now we're opening our beta, and here's the deal: • All the people who join will get free credits worth 10 signed docs • 12 months credit validity • No complexity • No hidden cost • No subscription commitment You can join the beta here - http://signwith.co That said, we see Google's entry in the signature space as validation. This event expanded the market with such massive awareness. Let me be clear: We’re not trying to be DocuSign, Google, or any other enterprise beast. We’re indie makers and building for: • The freelancers • The consultants • The indie and small business owners • and anyone who just needs a contract signed—fast, simple, no headaches. Here’s how SignWith works: • Upload your doc • Drop signature spots • Send it out and track • Pay per signed document That’s it. No subscriptions. No feature bloat. No crazy hidden charges and no complex pricing tiers. If you've read it so far, would love to see you on the other side. And hey, if you’ve got any feedback, suggestions, or just want to tell us what you need, reply here or drop me a DM. We’re all ears! Cheers! https://signwith.co/ December 20, 2024 at 06:33PM

Show HN: Rivet Actors – Durable Objects build with Rust, FoundationDB, Isolates https://ift.tt/epS89MP

Show HN: Rivet Actors – Durable Objects build with Rust, FoundationDB, Isolates Hello! We posted a Show HN for Rivet last year for our container orchestration project ( https://ift.tt/FyijHYO ). In that time, a lot has changed that I think HN will find interesting. Rivet is open-source actor infrastructure similar to Cloudflare's Durable Objects. Rivet itself already serves millions of MAU in production using our current container runtime – primarily for multiplayer games – and Rivet Actors are a new extension to support actor-like workloads. Rivet Actor's core primitives are RPC, state, and events. Actors are powered by Rust, V8 isolates (supports Deno), and FoundationDB. An architecture diagram is available here for [1]. If you're not familiar with FoundationDB, you're overdue to watch Dave Rosenthal's talk [3]. (I firmly believe it's by far the best permissively licensed database; if only it had a well maintained SQL layer.) Here's where Rivet's architecture gets fun – we don't rely on a traditional orchestrator like Kubernetes or Nomad for our runtime. Instead, our orchestrator is powered by an in-house actor-like workflow engine – similar to how FoundationDB is powered by their own actor library (Flow [4]) internally. It lets us reliably & efficiently build complex logic – like our orchestrator – that would normally be incredibly difficult to build correctly. For example, here's the logic that powers Rivet Actors themselves with complex mechanisms like retry upgrades, retry backoffs, and draining [2]. One of the reasons we built Rivet Actors is because we tried to replace most of our Redis-based realtime infrastructure with Durable Objects. The architecture allowed us to build realtime features much faster & efficiently, but the platform & APIs were needlessly rigid and difficult to use. Our goal is to build an actor-like platform that includes the bells and whistles required for developers to benefit from the actor model without the learning curve of tools like Erlang/OTP, Akka, or Orleans. Rivet Actors provides a few key benefits in flexibility over Durable Objects: - Open-source (Apache 2.0) – built to be self-hosted and deployed on-prem - Provides observability out of the box, no Logpush required - Rivet Actors support the Deno runtime, so NPM & JSR just works - @rivet-gg/actor [5] framework provides RPC, state, and events out of the box for faster bootstrapping; you can modify and deploy it yourself - Supports both V8 isolates & Docker-compatible containers so you can run any software you'd like, like Godot/Unity servers or video transcoding - Also supports TCP & UDP (we run games!) - Provides vanilla HTTP API for easy use with existing apps - Full control over regions There's plenty more that I don't have space to talk about.

Show HN: openai-realtime-embedded-SDK Build AI assistants on microcontrollers Hi HN! This is an SDK for ESP32s (microcontrollers) that runs against OpenAI's new WebRTC service [0] My hope is that people can easily add AI to lots of 'real' devices. Wearable devices, speakers around the house, toys etc... You don't have to write any code, just buy a device and set some env variables. If you have any feedback/questions I would love to hear! I hope this kicks off a generation of new interesting devices. If you aren't familiar with WebRTC it can do some magical things. Check out WebRTC for the Curious[1] and would love to talk about all the cool things that does also.

Show HN: Spotify and Apple Health Data as Art https://ift.tt/AceJXMU

Show HN: Spotify and Apple Health Data as Art For the longest time, I've been interested in the idea that the personal data we have logged across platforms can "paint" a pretty clear picture of who we are. And, as individuals, this will reveal fun and maybe sharable stories about us. So I made this app, Day by Data, to connect with and visualize your personal data like step count, music listening habits, and more into tiny visualizations and data art right on your iPhone. The launch version has a few year-in-steps breakdowns and a few Spotify data-visualizations. Over time, the goal is to make more data sources available to connect and empower users to learn from their personal data stored across these platforms. Think data about the food we eat, places we travel, or shows we watch. Data accessibility and cleanliness is the hardest part, but I'm always open to different sources and visualization types. Let me know what you think and if there are certain data sets you'd like to see visualized! https://ift.tt/w0ytxc7 December 21, 2024 at 12:12AM

Show HN: Solution to RSI and poor Mac dictation, accurately transcribes "memcpy" https://ift.tt/GOiuVpY

Show HN: Solution to RSI and poor Mac dictation, accurately transcribes "memcpy" About a year ago, my RSI had gotten to the point where I needed to take days off. I went down the rabbit hole of trackball mice, split keyboards, and dictation. Talon voice coding seemed like the dream solution I was looking for, but I just couldn’t get it right (here’s a link to the video I was inspired by: https://www.youtube.com/watch?v=0ZZb12Qp6-0 )). Around the same time, I increasingly adapted to new ways of life- tabbing, code suggests, completions, chat-based coding (I know, I know), and brainstorming with tools like Copilot, Codeium, Claude, and then Cursor. Mac's built-in dictation was my first attempt at a solution. It handled basic emails/messages fine but completely fell apart with technical terms. I couldn’t build a workflow around it. “malloc,” "memcpy," “Axum,” “Tauri”… these always had to be edited, and my wrists would still protest. I had been playing around with Whisper ever since it first came out (my work with MEL spectrograms and ECGs led me deep into OpenAI's Whisper). Once the whisper.cpp project got metal support, it worked beautifully on Apple Silicon Macs. What I ended up building - Local dictation tool - Works system-wide on Mac (any text input) - Custom dictionaries for technical terms/jargon - No cloud dependencies, no tracking, no signup, no subscriptions (one-time purchase) Technical details - Running Whisper Large Turbo locally (or quantized Whisper small/medium) - Sits in the background, requests accessibility permissions, and can paste text anywhere - Voice activity detection is experimental; haven't nailed the parameters yet. This will help with long recordings/live transcriptions - Sandboxed app, available through the Mac App Store My usage stats (just personal benchmarks) - Transcribed around 30k words over 2 weeks - Averaging 150 WPM vs my usual 55-60 WPM (significantly lower when I need to think—it’s not like one of those typing tests) - I’ve spoken for about 4 hours to it. So roughly 6-8 hours saved - Some occasional mistakes; there's a find and replace tool. I add random non-dictionary words for large prompts https://ift.tt/uZ25NLc https://ift.tt/uZ25NLc December 19, 2024 at 07:09PM

Show HN: TideCloak – Decentralized IAM for Security and User Sovereignty https://ift.tt/HM8tzxN

Show HN: TideCloak – Decentralized IAM for Security and User Sovereignty Hey HN! 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 needing to trust anyone else to keep it safe. Coming soon: - Identity Governance Administration to prevent super admin abuse. - User-sovereign digital assets, where assets are secured with unique decentralized keys to protect against mass breaches. We’ve just launched a free developer sandbox, and we’d love your feedback: https://ift.tt/bt20JDs It’s still early stages, and your input will help us improve. Thanks for taking a look - ask us anything! https://ift.tt/bt20JDs December 19, 2024 at 05:17PM

Show HN: Stringify.org – encode any text as a JavaScript string Do you ever want to embed a super long string in JavaScript, and find yourself escaping quotes or interpolations by hand? I find this comes up a lot, particularly when you're doing code generation stuff, because you need to have examples of code for the LLM, and that code often has strings embedded inside it. For example, take a look at the code properties in this JSON array[1]. Introducing stringify.org, the world's only correct-by-definition JavaScript string encoder website. It uses JSON.stringify, which is the only guaranteed method to output a string that is also valid JavaScript. It's in the spec.

Show HN: Repocheck – a CLI tool to get an overview of your local Git repos I built a CLI tool that lists out all the local git repos within a directory in an easy to read table format including relevant information such as last modified date and the status of branches in the repo, along with whether it is synced with remote or not. It also includes a bunch of flags to get exactly what you want in the format you want. I got this idea as I was trying organize the large amount of local git repos I had. I also found it particularly useful when traveling since I use a different device. In these cases, it is really helpful to know which local git repos I forgot to push commits or have fallen behind the remote version. Hope you find it really useful, let me know if you like it and also if you have any feedback for it! https://ift.tt/3gWHtxG December 17, 2024 at 10:31PM

Show HN: NCompass Technologies – yet another AI Inference API, but hear us out https://ift.tt/YmL6VrW

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 minimizing the number of GPUs required to maximize the number of concurrent requests you can serve, without degrading quality of service. We’re still building a lot of our optimizations, but we’ve released what we have so far via our API. Compared to vLLM, we currently keep time-to-first-token (TTFT) 2-4x lower than vLLM at the equivalent concurrent request rate. You can check out a demo of our API here: https://ift.tt/QlakEBX As a result of the optimizations we’ve rolled out so far, we’re releasing a few unique features on our API: 1. Rate-Limits: we don’t have any Most other API’s out there have strict rate limits and can be rather unreliable. We don’t want API’s for open source models to remain as a solution for prototypes only. We want people to use these APIs like they do OpenAI’s or Anthropic’s and actually make production grade products on top of open source models. 2. Underserved models: we have them There are a ton of models out there, but not all of them are readily available for people to use if they don’t have access to GPUs. We envision our API becoming a system where anyone can launch any custom model of their choice with minimal cold starts and run the model as a simple API call. Our cold starts for any 8B or 70B model are only 40s and we’ll keep improving this. Towards this goal, we already have models like `ai4bharat/hercule-hi` hosted on our API to support non-english language use cases and models like `Qwen/QwQ-32B-Preview` to support reasoning based use cases. You can find the other models that we host here: https://ift.tt/6aVbDhn. We’d love for you to try out our API by following the steps here: https://ift.tt/DcMIvKR . We provide $100 of free credit on sign up to run models, and like we said, go crazy with your requests, we’d love to see if you can break our system :) We’re still actively building out features and optimizations and your input can help shape the future of nCompass. If you have thoughts on our platform or want us to host a specific model, let us know at hello@ncompass.tech. Happy Hacking! https://ift.tt/ghtymbH December 16, 2024 at 07:07PM

Show HN: I made the slowest, most expensive GPT https://ift.tt/GSv19us

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, on Reddit https://ift.tt/j5lWiKX... - because there's so many opinions floating around, a one-shot RAG search + LLM isn't going to have enough context to find how everyone thinks. And obviously, offline GPTs like o1 and Sonnet/Haiku aren't going to have the latest updates if a resort closes for example. So I’ve spent the last few months experimenting with a new project that's basically the most expensive GPT I’ll ever run. It runs search queries through ChatGPT, Claude, Grok, Perplexity, Gemini, etc., then aggregates the responses. For added financial tragedy, in-between it also uses multiple embedding models and performs iterative RAG searches through different search engines. This all functions as sort of like one giant AI brain. So I pay for every search, then every embedding, then every intermediary LLM input/output, then the final LLM input/output. On average it costs about 10 to 30 cents per search. It's also extremely slow. https://ithy.com I know that sounds absurdly overkill, but that’s kind of the point. The goal is to get the most accurate and comprehensive answer possible, because it's been vetted by a bunch of different AIs, each sourcing from different buckets of websites. Context limits today are just large enough that this type of search and cross-model iteration is possible, where we can determine the "overlap" between a diverse set of text to determine some sort of consensus. The idea is to get online answers that aren't attainable from any single AI. If you end up trying this out, I'd recommend comparing Ithy's output against the other GPTs to see the difference. It's going to cost me a fortune to run this project (I'll probably keep it online for a month or two), but I see it as an exploration of what’s possible with today’s model APIs, rather than something that’s immediately practical. Think of it as an online o1 (without the $200/month price tag, though I'm offering a $29/month Pro plan to help subsidize). If nothing else, it’s a fun (and pricey) thought experiment. https://ithy.com December 13, 2024 at 10:05PM

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!

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 the need to copy-paste and fix formatting issues, Pointer aims to make writing and editing more efficient and enjoyable. It's like having an intern who understands exactly what you need and implements it directly in your document. I'd love for you to try it out and let me know if it improves your workflow. You can find Pointer on the Chrome Web Store. Looking forward to your feedback and any questions you might have! https://ift.tt/2r3dWAk December 10, 2024 at 12:12AM

Show HN: OpenInt (YC W23) Open-Source iPaaS to Ship Product Integrations Quickly https://ift.tt/UWTawcN

Show HN: OpenInt (YC W23) Open-Source iPaaS to Ship Product Integrations Quickly Hi HN, we’re the team behind OpenInt ( https://openint.dev ). We started building a unified API for crypto payments at Map3 (YC W23), but scaling dozens of custom integrations for each customer was painful and repetitive. We learned how valuable it would be to have a platform that lets any team quickly stand up private and fully controlled integrations without reinventing the wheel each time. OpenInt is an open-source integration platform as a service (iPaaS) that helps you ship product integrations in hours, not weeks. We just participated Mega Launch Week (Dec 2–6 https://ift.tt/ABrsdxE ) and introduced ( https://ift.tt/gSje1bn ): - Dec 2: OpenInt – Open-source iPaaS platform. - Dec 3: @OpenInt/Connect – Fully featured integrations page for your app. - Dec 4: OpenInt Sync – Automated data syncs straight into your database. - Dec 5: OpenSDKs – Typesafe SDKs with an auth proxy for any API. - Dec 6: Orchestrate & Our Partner Program – Unified aggregator orchestration plus our partner ecosystem (initial ones are also other OSS YC companies). We think the above makes OpenInt the LAST integration you’ll ever need. If there’s any connector missing, tell us about it, and either we or one of our partners will write it for you in 72h for $1000. We went through Y Combinator W23 and are now fully committed to building an open ecosystem. The stack is mostly TypeScript on Cloudflare Workers with Postgres for storage—designed to be easy to run and scale on your own infra. Long term, we want to see open-source AI agents assist developers in auto-generating and maintaining integrations and SDKs, collaborating directly within the repo. Here’s[1] a 1-minute demo video to show how fast you can launch an integration. Check out the integrations list, star our GitHub repos (OpenInt[2] | OpenSDKs[3]), or hop into our Slack community (signup via https://openint.dev ) to say hi. [1]: https://www.youtube.com/watch?v=FpG7otZZhRw [2]: https://ift.tt/eLT2WNP [3]: https://ift.tt/lNRDV2h We're not quite ready for a full Launch HN yet (hence the Show!), but we’d love your feedback—tell us what’s missing, where we can improve, or what you’d like to build with OpenInt! https://ift.tt/eLT2WNP December 6, 2024 at 11:00PM

Show HN: Checkmate, a server and infrastructure monitoring application https://ift.tt/UNjLai1

Show HN: Checkmate, a server and infrastructure monitoring application We just released Checkmate 2.0 (formerly BlueWave Uptime). Originally designed as a simple uptime manager, Checkmate has evolved into an infrastructure monitoring tool. With the addition of our lightweight Go-based server agent (Capture) it's possible to monitor key metrics like CPU, RAM, and disk usage across remote servers. 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. The project gained some traction with 31 contributors and this version itself had 13 contributors. - Server: https://ift.tt/d0e6ric - Agent: https://ift.tt/njIlf8z - Demo: https://ift.tt/NZvxMos (The username is uptimedemo@demo.com and the password is Demouser1! ) https://ift.tt/d0e6ric December 6, 2024 at 04:08AM

Show HN: Fifty – A game where you match numbers until you clear the board https://ift.tt/HULYxPW

Show HN: Fifty – A game where you match numbers until you clear the board Hey everyone, I'm Fabio, a very long time lurker here. Today I want to celebrate and share with you, again, a game that I conceived more than 8 years ago. I shared it last week with all its history (if you're curious) [1], but it just stayed in the "shownew" and never reached the main "show" page, hopefully this time it'll do better (:crossed_fingers:)! What changed since last week? Today I've also published the mobile apps for both iOS and Android (last week it was just web), which are also my first mobile apps ever. So I believe it's still a worthwhile post and something to show :) I'd love to know what you think about it. I'll try to answer to everyone during the day.

Show HN: Banan-OS, an Unix-like operating system written from scratch https://ift.tt/GKXQ1R7

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/oszTLCf December 6, 2024 at 01:54AM

Show HN: Guard – LLM agent that scans your AWS account for misconfigs I wanted to do a complete audit of my AWS account but was dissatisfied with the existing tools. Many of them are clunky to use, and their verbose scan outputs are difficult to understand.

We use AI to analyze the filings the second they are released. Free accounts to look at real filings (automatically updated) are available to any who sign up. If you have any questions feel free to ask. https://docdelta.ca December 4, 2024 at 02:25AM

Show HN: Video Conferencing on the CPU of a WiFi Router/AP with meshing https://ift.tt/MgtosWz

Show HN: Video Conferencing on the CPU of a WiFi Router/AP with meshing I'm releasing an early version of a minimal WebRTC SFU video relay server, with the major differentiators being it can easily run on OpenWrt and it has the ability to trunk all tracks to the cloud, and vice versa: Code: https://ift.tt/tRkG5vd Demo: https://ift.tt/TLX8kUZ * Golang with Pion. 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. I should test with more! If you try it let me know how it goes. https://ift.tt/tRkG5vd December 3, 2024 at 10:49PM

Show HN: Glyph3D – A 3D text visualizer for macOS and iOS / iPadOS https://ift.tt/Jjuw8Pv

Show HN: Glyph3D – A 3D text visualizer for macOS and iOS / iPadOS Hello internet folks! I'm happy to share the first TestFlight release of Glyph3D, a 3D text visualizer for macOS and iOS. It's free, supports pretty much any utf8 data, and is a pretty interesting way to navigate your repositories or data directories without the limitations of standard text windows! Download and bookmark for macOS and iOS: https://ift.tt/mz20O1v - You should be able to download public repos from GitHub and render them. - Play with opening and closing windows. I've disabled many of the in-flight features to keep user confusion down, and will be creating additional documentation about those features as they are implemented. - Editing works but there's nowhere to put the data for now ;) The user can pull from the app's caches if they want for now, but there's no actual repo support - by design. Bringing in the git SDK, or accessing the CLI, is a bit more work and danger than I want to include in the app right now. Any feedback is welcome, and if you'd like to support me or the project in any way, please reach out to me, and I'll be looking forward to that conversation. https://ift.tt/ukOfa7L December 2, 2024 at 04:52AM
