Show HN: I made a gamified card collector to celebrate personal achievement(App) https://bit.ly/42OVqKg

Show HN: I made a gamified card collector to celebrate personal achievement(App) Hi HN, Last month me and my friend tried Geocaching, an outdoor activity for your to find treasure boxes. Even though we didn't find the treasure, we both think this is worth celebrating. As a game designer and card game lover, I hoped it would be so cool if I can have achievements recorded as cards, and review them as my collections. So I made an App called Achiva, and now it's available on App Store. There are achievements like: - Sleep for 12 hours - Geocaching (of course) - Build Lego but also serious achievements like: - Becoming a parent - Buying a car - First Job I hope you will like it!

Show HN: OSle – A 510 bytes OS in x86 assembly https://bit.ly/4lY6X2O

Show HN: OSle – A 510 bytes OS in x86 assembly (sorry about double posting, I forgot to put Show HN in front in the original https://bit.ly/4cYasSJ thread) Hey all, As a follow up to my relatively successful series in x86 Assembly of last year[1], I started making an OS that fits in a boot sector. I am purposefully not doing chain loading or multi-stage to see how much I can squeeze out of 510bytes. It comes with a file system, a shell, and a simple process management. Enough to write non-trivial guest applications, like a text editor and even some games. It's a lot of fun! It comes with an SDK and you can play around with it in the browser to see what it looks like. The aim is, as always, to make Assembly less scary and this time around also OS development.

Show HN: CapOS – A responsibility-gated OS stack with signed process execution https://bit.ly/44k5q0B

Show HN: CapOS – A responsibility-gated OS stack with signed process execution We’ve built a functional prototype for an operating system layer that rejects the classic trust model. Every process, network access, and system action is explicitly scope-bound to a signed capability token (CapToken) – backed by a cryptographic wallet and domain-specific responsibility structure. Key Components: CapToken authentication for all system actions CapAuditDaemon (feedback, incidents, signed system state) Feedback replaces control – the system acts on effect, not permission CapNFTs as soulbound responsibility certificates VPN routing via chain-verified nodes (CapVPNRegistry.sol) Whitebook & mathematical formalization published on Zenodo No ACLs, no root, no anonymous processes. Only signed, trackable responsibility. Period. GitHub: https://bit.ly/4lWu0er Docs/Whitebook: https://bit.ly/42YGJoj Feedback kills control. Power demands responsibility. https://bit.ly/42YGEkv May 2, 2025 at 02:53AM

Show HN: Learn You Galois Fields for Great Good https://bit.ly/4k06ECT

Show HN: Learn You Galois Fields for Great Good Hi All, I've been writing a series on Galois Fields / Finite Fields from a computer programmer's perspective. It's essentially the guide that I wanted when I first learned the subject. I imagine it as a guide that could gently onboard anyone that is interested in the subject. I don't assume too much mathematical background beyond high-school level algebra. However, in some applications (for example: Reed-Solomon), familiarity with Linear Algebra is required. All code is written in a Literate Programming style. Code is written as reference implementations and I try hard to make implementations understandable. Currently I've completed the following sections: 01: Group Theory 02: Field Theory 03: Implementing GF(p) 04: Polynomial Arithmetic 05: Polynomial Fields GF(p^k) 06: Implementing GF(p^k) 07: Implementing Binary Fields GF(2^k) 08: Cyclic Redundancy Check (CRC) 09: Linear Algebra over Fields Future sections are planned: Reed-Solomon Erasure Coding AES (Rijndael) Encryption Rabin Fingerprinting Extended Euclidean Algorithm Log and Invlog Tables Elliptic Curves Bit-matrix Representations of GF(2^k) Cauchy Reed-Solomon XOR Codes Fast Multiplication with FFTs Vectorization Implementation Techniques I hope this series is helpful to people out there. Happy to answer any questions and would love to incorporate feedback. https://bit.ly/4jCkk76 May 1, 2025 at 10:49PM

Show HN: Wrap Notes – One big text file with multiple projections Hi HN, I'm working on a notes app and am keen to gauge interest. The core idea is being able to re-arrange the note hierarchy: Date -> Topic -> Note for timeline view Topic -> Date -> Note for topic view I believe these two projections add significant value to a solid markdown note app foundation, without unnecessary bloat or distraction. Thanks! https://bit.ly/4iWecFX April 29, 2025 at 08:16AM

Show HN: Discorss – RSS Feeds for Discord https://bit.ly/42whw5A

Show HN: Discorss – RSS Feeds for Discord I made my own Discord bot for managing RSS feeds, called Discorss. Discorss is open source, has AI summarization, automatic paywall skips, and can be entirely managed with slash commands. Best of all – self hosting is very cheap and trivial with Railway, so you can add your own customizations to how the RSS bot works. I've been using a personal Discord server as my RSS hub – it's convenient and I can setup different channels for different newsfeeds (i.e. an HN channel for the frontpage). I was using https://bit.ly/4dcq9Gh – but it's barely had any changes, and needing to manage the external UI has been annoying.

Show HN: I Built ATS Master – A Tool to Help Job Seekers Optimize Their Resumes Hi HN! I'm a solo developer, and over the past few months, I've been building a tool called ATS Master to help job seekers improve their resumes and land more interviews. During my own job search, I struggled with: Tailoring resumes manually to each job description Low ATS (Applicant Tracking System) scores leading to automatic rejections Not knowing how well my resume actually matched the roles I was applying for So, I built ATS Master, which: Reads the job description Analyzes your resume content Suggests optimizations to improve ATS compatibility Estimates your ATS score Helps you optimize your LinkedIn profile Lets you download a polished PDF resume I'm launching it publicly now and would love to hear your honest feedback — good, bad, or brutal.

Show HN: The #1 Reason Your Product Fails – Ignoring User Feedback https://bit.ly/4jtgCwH

Show HN: The #1 Reason Your Product Fails – Ignoring User Feedback I’ve spent months researching why solo-built products stall—and time and again it comes down to one culprit: poor feedback collection. Without an easy way to capture, organize, and act on what your users are saying, insights slip through the cracks and your roadmap veers off course. That’s why I built Feedaura, a lightweight widget you drop into your site to: Automatically gather feedback right where users are engaging (no more chasing down emails or scattered notes) Analyze every comment with AI, categorizing sentiment, feature requests, and bug reports on the fly Display it all in a simple dashboard, so you can filter, search, and prioritize in seconds Keep your team in sync, with real-time updates as new feedback rolls in Feedaura makes it effortless for solo developers and indie makers to stay laser-focused on what users really want—so your next release hits the mark.

Show HN: ImgDetect – AI Image Detector to Identify Fake and AI-Generated Images https://bit.ly/3ErAOjr

Show HN: ImgDetect – AI Image Detector to Identify Fake and AI-Generated Images Hi HN community, I recently built an app called *ImgDetect*, an AI-powered tool that detects AI-generated, manipulated, or fake images. How it works: - Upload an image (or paste a link). - ImgDetect analyzes the image using multiple AI models. - It provides a probability score and highlights possible manipulations. Why I built it: With the rise of AI-generated content, it's becoming harder to distinguish real from fake. I wanted to create a lightweight, privacy-focused tool that anyone can use without technical knowledge. Link: - App Store / Download: https://apple.co/44cRd5M... Features: - Fast AI detection - Privacy-focused: No image data is stored - Available on mobile and web I'd love to hear your feedback and suggestions! If you find any bugs or have ideas for improvement, please feel free to share. Thanks a lot for checking it out! https://apple.co/42KeRUz April 27, 2025 at 06:31AM
