Show HN: MSDL – A minimal description language and editor for system diagrams https://bit.ly/3HBcigW

Show HN: MSDL – A minimal description language and editor for system diagrams When I dug into systems theory, the thing I found missing early on was a good editor for diagrams while exploring or explaining systems. So I used Graphviz, and found myself typing boilerplate and constructions that I found cumbersome. The editor I envisioned would be close to natural language, with a minimal syntax and a clear, but flexible semantics. So I started building a DSL and an editor for myself, but soon found there was a lot to learn, and a lot of pitfalls to avoid. It grew, and I had to revisit my goals with this project. That was the moment I thought: let me give back to the community. I created a spec for the language I had in mind, Minimal Systemigram Description Language. And a browser based and wails based desktop editor. And a Github page. If you want to jump there right away: https://bit.ly/4e3wYKx... . There is extensive help in the editors. To check it and learn, I recreated diagrams from introductory books I read. This in turn made me update the spec and the editor again. Today I released it on Github in version 0.1.0 for you to assess. It has a Github pages version of the editor for immediate trial, the spec, the desktop editors and the library, all open source. Builds are there for Ubuntu, Mac and Windows, the latter via Github Runners, and I tested all of them on the systems I have (one of each :D). I am far from a good programmer, but I put a lot of love into it. I hope it shows in the details. If you are a systems practicioner, learner, teacher, or just interested, it might be something for you. Let me know what you think, good or bad. Happy to answer questions. https://bit.ly/3SVjoiC June 15, 2025 at 04:44PM

Show HN: Zeekstd – Rust Implementation of the ZSTD Seekable Format https://bit.ly/4l5M8RH

Show HN: Zeekstd – Rust Implementation of the ZSTD Seekable Format Hello, I would like to share a Rust implementation of the Zstandard seekable format I've been working on. Regular zstd compressed files consist of a single frame, meaning you have to start decompression at the beginning. The seekable format splits compressed data into a series of independent frames, each compressed individually, so that decompression of a section in the middle of an archive only requires zstd to decompress at most a frame's worth of extra data, instead of the entire archive. I started working with the seekable format because I wanted to resume downloads of big zstd compressed files that are decompressed and written to disk on the fly. At first I created and used bindings to the C functions that are available upstream[1], however, I stumbled over the first segfault rather quickly (it's now fixed) and found out that the functions only allow basic things. After looking closer at the upstream implementation, I noticed that is uses functions of the core API that are now deprecated and it doesn't allow access to low-level (de)compression contexts. To me it looks like a PoC/demo implementation that isn't maintained the same way as the zstd core API, probably that's also the reason it's in the contrib directory. My use-case seemed to require a complete rewrite of the seekable format, so I decided to implement it from scratch in Rust using bindings to the advanced zstd compression API, available from zstd 1.4.0. The result is a single dependency library crate[2], and a CLI crate[3] for the seekable format that feels similar to the regular zstd tool. Any feedback is highly appreciated!

Show HN: Personalized Wealth Management – Institutional Meets Consumer https://bit.ly/4kL0Uh4

Show HN: Personalized Wealth Management – Institutional Meets Consumer Problem: If you have less than $100k to invest, you get a robo-advisor that asks you 5 questions and dumps you into one of three cookie-cutter portfolios. If you have more than $100k, you get a human advisor who charges 1-1.5% annually to... basically do the same thing with a smile and calming voice attached. Meanwhile, institutional investors get custom strategies built around specific durations, target dates, tax situations and actual investment goals. Not because the math is harder—but because the economics only work at scale. Here's the thing: Both traditional advisors and robo-advisors maximize profit by minimizing choice and directing capital into the bias strategies that generate them additional margins. Both just tweak a risk slider and call it "personalization." But institutional-grade portfolio construction doesn't have to be exclusive to the wealthy. The road was paved by platforms like Plaid, brining API connectivity—platforms and asset aggregation into the mainstream. Modern AI completes the picture by making true personalization economically viable via "micro-advise". No asset transfers, no new custodians, just sophisticated strategies based on your financial goals executed where you already invest coupled with personalized financial planning & budgeting. Technical Solution: We've built our MVP wealth management platform that creates truly personalized portfolios by combining institutional capital market expectations stemming 30+ global asset classes. All available through low-fee publicly available ETFs. Our approach: - SEC licensed & compliant Registered Investment Advisor - Generates unlimited unique portfolio combinations optimized for risk, return & goal specifics. - Personalizes to individual goals, not generic risk buckets. - Learns and improves from every user interaction - Provides institutional-grade sophistication without human bottlenecks - Removes manager bias for in-house strategies - Uses a "glidepath" approach similar to the US retirement target-date structure to maximize achievement certainty of important life goals (down-payment, retirement, etc) - Seeks to bring elements of habit forming platforms (like Duolingo) into retail wealth. Business Model Innovation: -Non-custodial + AI architecture enables subscription pricing ($10/month) instead of AUM fees. Users keep control of assets while getting personalized institutional strategies. Research Validation: - Glidepath strategies delivered higher values in 76% of scenarios (T. Rowe Price) - Global diversification outperformed domestic-only in 96% of 3-year periods (Hübner) - Chance of success metrics for significant life goals like retirement & major milestones are measurably improved via behavioral advantages & sequence risk protection (T. Rowe Price). Early Results: -Alpha users report 90%+ cost reduction vs. traditional platforms with superior personalization. Institutional style portfolios achieving goal-specific optimization that would cost minimum 10x elsewhere. -Base model portfolios have outperformed comparable portfolios from existing market incumbent robo-platforms on both an absolute & risk adjusted basis in H1 2025. What's Different: This isn't another robo-advisor using basic mean reversion. It's personalization that helps you understands and discover your specific goals and adapts continuously. Think "personal wealth manager in your pocket" rather than "generic portfolio assignment." All that, in a consumer product platform designed to empower retail investors and keep them engaged. Next Steps: Currently in invite-only alpha at https://bit.ly/448dlMT. We focused early on the portfolio construction & delivery process and are now building out the consumer-facing aspects of the web application. Looking for feedback from the HN community on our approaches to financial personalization. https://bit.ly/4nhUuI2 June 15, 2025 at 11:58PM

Show HN: Gem and I built an open-source app to learn Japanese https://bit.ly/3HHsRrq

Show HN: Gem and I built an open-source app to learn Japanese I've been fascinated by the Japanese language and culture for a while now, and I wanted to create a simple, no-fuss way for beginners to get started. So, I built *[Nihongo]( https://bit.ly/3FYL2bB )*, a free and open-source web app designed to help you learn the fundamentals of Japanese in about a month. The name of the app, Nihongo (日本語), is the Japanese word for the "Japanese language." You can check it out here: *[ https://bit.ly/3FYL2bB ]( https://bit.ly/3FYL2bB )* And for those who like to tinker, the code is available on GitHub: *[ https://bit.ly/4dYuKfg ]( https://bit.ly/4dYuKfg )* The "learn in 30 days" idea isn't about achieving fluency in a month, which we all know is impossible. Instead, the goal is to provide a structured and manageable learning path that covers the essential building blocks of the language in a short period. I wanted to create something that feels less intimidating than many comprehensive (and often expensive) resources out there. *What the app covers:* The app is structured into a series of lessons that you can follow at your own pace. It starts with the absolute basics and gradually introduces more complex concepts: * *The Japanese Writing Systems:* Detailed lessons on Hiragana and Katakana, the two phonetic scripts that are the foundation of written Japanese. * *Essential Grammar:* I've focused on the core grammatical structures you need to start forming your own sentences. * *Core Vocabulary:* You'll learn a curated list of high-frequency words that are immediately useful in everyday conversation. * *Practical Phrases:* The app includes common greetings and phrases that you can start using right away. *Why I built this:* I started building this project while testing the latest Gemini 2.5 models on Google AI Studio, and with the Code assistant and Cloud Run I was able to get it to production in less than 3 hours. This as a personal project to solidify my own understanding of Japanese and to build something useful for others who are just starting their learning journey. I'm a big believer in the power of open-source and wanted to create a resource that is accessible to everyone. This is very much a passion project, and I'm still actively working on it. I'd love to get your feedback, suggestions, and of course, any contributions on GitHub are more than welcome. Let me know what you think! I'm here to answer any questions you might have. https://bit.ly/3FYL2bB June 14, 2025 at 12:04AM

Show HN: I built a cleaner YouTube – no ads, sponsors, or doomscrolling Hi HN! I built SkipCut it’s like an ad-free, distraction-free YouTube with useful extras: background play, SponsorBlock, dark mode, playlist support, local history, download/share buttons… and it works on any device. No install. No login. Here’s the best part: It works just by replacing "youtube" with "skipcut" in the video link. You skip all the boring stuff — ads, sponsors, intros, silence, filler and just watch what matters. Why it’s different: No comments. No suggested videos. No clickbait. I made this for my kid, I create a playlist and just send a SkipCut link like: https://bit.ly/45mc7jm It plays only those videos and stops the doomscrolling. Just replace youtube with skipcut in the URL of any video Example: https://bit.ly/4jPXs3k No signup required Would love your feedback, ideas, and bug reports!

Show HN: Claude Slash Command Suite inspired by Anthropics best practices guide https://bit.ly/4kPV3qA

Show HN: Claude Slash Command Suite inspired by Anthropics best practices guide I built a collection of professional slash commands for Anthropic's Claude Code that provide structured workflows for common software development tasks. These commands are directly inspired by and adapted from Anthropic's own claude-code-best-practices (https://bit.ly/3HFnglo) documentation, translating their recommendations into executable workflows. The suite includes commands for: • Comprehensive code reviews with security and performance analysis • End-to-end feature development with planning, implementation, and testing • Architectural analysis and design pattern assessment • Security audits and vulnerability scanning • GitHub issue resolution with root cause analysis • Performance optimization and build improvements Each command follows a systematic approach based on Anthropic's best practices, breaking complex tasks into manageable steps. Instead of ad-hoc AI interactions, you get consistent, thorough workflows that adapt to any codebase. The commands work through Claude Code's slash command system - just type `/project:code-review` or `/project:create-feature user-authentication` and Claude follows the predefined workflow. Installation is straightforward with an interactive script that can install project-specific or globally. The commands are fully customizable markdown files, so you can adapt them to your team's specific requirements. I hope others find it useful! https://bit.ly/4n0gmqY June 13, 2025 at 03:05AM

Show HN: AuraCoder – Gen AI Learning Platform https://bit.ly/4jKNeBa

Show HN: AuraCoder – Gen AI Learning Platform Hey HN, I've been pouring my time into this side project and I think I finally got an MVP up! I'm really excited about it. I'm really passionate about combining LLMs and learning. It seems like one of the best firsts for the tech. And so I built a site where all the content is generated. As I've been building, I'm always torn between building something more general purpose where you can learn anything vs building something targeted where the generation can be more tailored. Currently, its the latter so the site is focused on data structures and algorithms. That's something I've ground out recently so just familiar with what good content might look like and it was helpful in getting the prompt engineering to generate decent content. The site can generate both Lessons and Challenges. And they are a bit tailored to you. You can set settings about what kind of preferences you have. Tone of voice, depth, even an open text that gets feed into the prompt. I tried "Include a cat joke in every lesson" and I thought that was pretty entertaining It also takes into account your current skill level on different concepts. But I also think I need to lean in more on the customization. That seems to be the biggest way AI generated content can differentiate. I think its been hard to generate content that's really as good as human expert generated stuff, but it can be tailored to the user. So really interested in ideas in that vein. And in general, any advice is greatly welcomed. Also of course willing to AMA. Happy to answer any questions about the tech stack, the apps architecture, etc Sorry the site requires sign-up. I've thought about allowing anonymous users, but haven't implemented that yet. However, the site is free, and I'm not even doing any kind of email verification. So I won't judge you if you go with "some-fake-email@example.com" Hope your day is going well and all the best! https://bit.ly/44detzV June 12, 2025 at 03:01AM

Show HN: The Roman Industrial Revolution that could have been This is a proof-of-concept comic book that asks: What if knowledge from 2025 reached Rome and kicked off an industrial revolution? The story follows two voices: - Ulysses, a present-day archaeologist who finds a glowing slate in the dig site. - Marcus, an educated household slave in 79 AD who replies on that slate. Why I’m posting: I’d love narrative feedback. – Does the story make sense? – Are Ulysses and Marcus believable? – Which directions would you explore next (politics, tech, moral fallout)? What’s live today - First issue, 25 rough pages. - No paywall; just a PDF. Next steps Regular releases toward a 8 or 10 issues collection. I’ll revise based on your critiques and wild speculations. Grateful for any thoughts on pacing, historical plausibility, or character depth. Thanks for reading! https://bit.ly/4kMWvdt June 12, 2025 at 12:51AM

Show HN: Open-source Go Challenges – Interactive practice for interviews https://bit.ly/4l2j6T7

Show HN: Open-source Go Challenges – Interactive practice for interviews Hey HN, For a while, I've been looking for a comprehensive, free, and interactive platform to practice Go, especially specific concepts like concurrency, interfaces, and goroutines, with immediate feedback. Since I couldn't find exactly what I needed, I decided to build one myself: an open-source GitHub repo with 30 Go challenges. The goal is to provide a structured way to learn Go by doing. Each challenge comes with learning materials and automated tests. Users can run their code directly in a web interface, get instant test results, and even track performance. There's also a leaderboard for some friendly competition. I've tried to make it easy to jump in without much setup. You can simply fork the repo, solve challenges, and even get your solutions auto-judged via GitHub Actions if you push them. It's still evolving, and I'd love to get feedback from the HN community. What challenges would you like to see added? Any thoughts on the testing or documentation? Thanks for checking it out!
