Show HN: I made a tool to generate photomosaics with your pictures
18 by jakemanger | 4 comments on Hacker News.
Hi HN! I wanted to make some photomosaics for an anniversary gift, but I ended up building this tool and turning it into a free website that anyone can use. For those who don’t know, a photomosaic is an image made up of many smaller tile images, arranged in a way that forms a larger, recognisable picture. The best part? Everything runs directly in your browser. No files are uploaded, and there’s no sign-up required.

Show HN: Apple Health MCP Server
5 by _neil | 0 comments on Hacker News.
Hey HN, This is an MCP server to chat with Apple Health data. I built it because I'm working on (yet another) personal trainer tool that keeps track of my workout goals, etc. and does scheduling for me. Part of that is weekly check-ins. I thought pairing those check-ins with sensor data could be useful, so here we are. It seems there isn't a way to automate access to Apple Health data, so this relies on an iOS app that can quickly/easily export key data to CSV. So the process at the moment is to export the data every Sunday before doing a check-in. More steps than I'd like, but in practice isn't a big lift. Under the hood this is mostly a thin wrapper around duckdb. There's a video of it in action here: https://ift.tt/qD76TC1

Show HN: Header-only GIF decoder in pure C – no malloc, easy to use
20 by FerkiHN | 16 comments on Hacker News.
I built a lightweight GIF decoder in pure C, ideal for embedded or performance-critical environments. It’s header-only, zero dynamic memory allocations, and fully platform-independent. Supports both static and animated GIFs, with turbo and safe decoding modes. Works great on microcontrollers, IoT devices, and anything with a framebuffer. Would love feedback or ideas where this could be useful. Github: https://ift.tt/KkpMeDY...

New top story on Hacker News: Show HN: The Magic of Code – book about the wonders and weirdness of computation
Show HN: The Magic of Code – book about the wonders and weirdness of computation
8 by arbesman | 3 comments on Hacker News.
I recently published a book called “The Magic of Code” which is about the delights of the computational world, examining computing as a kind of “humanistic liberal art” that connects to so many topics, from art and biology to philosophy and language. The link I’ve shared is to a page on my book’s website where you can download a pdf of the introduction, to give HN readers a taste of what is inside. Right now there is so much worry and concern around technology that I feel like some people—though not the folks here—have forgotten how much fun that code and computation can also be. So I wanted to rekindle some of that sense of wonder. But, as I’ve written elsewhere, this is also the kind of book I wish I had when I was younger and getting interested in computers. I’ve always enjoyed the kinds of writing that talks about computing but in the context of so many other big ideas, especially ones I’ve explored at various points in my own life, from evolution to simulation. And that’s what I tried to do. But while “The Magic of Code” is certainly for a wide audience, and for people who are unfamiliar with programming and code, I’ve also (hopefully!) designed it to be of interest to those who are more expert in this realm, with lots of rabbit holes and strange ideas to pursue. And if there exists a genre of book to explain to outsiders why you love a topic, this is in that genre, for computing and code. I think the HN community will really enjoy it.

New top story on Hacker News: AGI Is Mathematically Impossible (3): Kolmogorov Complexity
AGI Is Mathematically Impossible (3): Kolmogorov Complexity
16 by ICBTheory | 5 comments on Hacker News.
Hi folks. This is the third part in an ongoing theory I’ve been developing over the last few years called the Infinite Choice Barrier (ICB). The core idea is simple: General intelligence—especially AGI—is structurally impossible under certain epistemic conditions. Not morally, not practically. Mathematically. The argument splits across three barriers: 1.Computability (Gödel, Turing, Rice): You can’t decide what your system can’t see. 2.Entropy (Shannon): Beyond a certain point, signal breaks down structurally. 3.Complexity (Kolmogorov, Chaitin): Most real-world problems are fundamentally incompressible. This paper focuses on (3): Kolmogorov Complexity. It argues that most of what humans care about is not just hard to model, but formally unmodellable—because the shortest description of a problem is the problem. In other words: you can’t generalize from what can’t be compressed. ⸻ Here’s the abstract: There is a common misconception that artificial general intelligence (AGI) will emerge through scale, memory, or recursive optimization. This paper argues the opposite: that as systems scale, they approach the structural limit of generalization itself. Using Kolmogorov complexity, we show that many real-world problems—particularly those involving social meaning, context divergence, and semantic volatility—are formally incompressible and thus unlearnable by any finite algorithm. This is not a performance issue. It’s a mathematical wall. And it doesn’t care how many tokens you’ve got The paper isn’t light, but it’s precise. If you’re into limits, structures, and why most intelligence happens outside of optimization, it might be worth your time. https://ift.tt/uASHYDq Happy to read your view.

Show HN: Typeform was too expensive so I built my own forms
13 by preetsuthar17 | 2 comments on Hacker News.
Hey HN, I'm a solopreneur and run a web design agency. I create open-source apps, but I also work as a freelancer and designer. I was accepting any new freelance project via forms on my agency website. I was using Typeform, but as time went by and more people submitted forms, it got more and more expensive. That time, I thought to use Google Form, but it was way too blocky and looked very unprofessional on my agency website. So I thought to build my own forms for my own usage, and it turns out it almost doubled form submissions and inquiry calls. I was happy, so I thought to build it for everyone and make it open-source. I added AI functionalities using Vercel AISDK. I can generate forms almost instantly using AI and also added analytics AI so that users can talk with their forms—more like talk with their analytics data. I hope this product will be as helpful to you as it was for me. Would love your feedback pls Preet

Show HN: Dev atrophy test – Can you still code without AI?
7 by mrborgen | 2 comments on Hacker News.
Hey HN, I'm Per from Scrimba (YC S20), the code-learning platform. There's been a lot of talk lately about whether AI tools are causing skill atrophy amongst developers. We get a front-row seat to this, and we see more and more students struggle with basic concepts, and building apps on their own. This is almost always a consequence of relying too much on ChatGPT and vibe coding tools. So we built a small side project: https://devatrophy.com It's a test of your core web dev knowledge — no handholding, no back rubs, no AI autocomplete. Just you, your brain, and 10 questions. There are three levels (Noobie, Le Chad, Hardcore), and the questions cover HTML, CSS, JavaScript, databases, and Node. You’ll get a score at the end, plus a downloadable certificate for bragging rights (or public shaming). Would love for you to try it and tell us what you think. And would be curious to hear if you're feeling any signs of "dev atrophy" yourself, or in your team? PS: Ironically we decided to produce it by vibe coding on V0. Oh the irony.

Show HN: Weather Watching
16 by walz | 1 comments on Hacker News.
I was walking around New York last month during some light rain and noticed about half the people had umbrellas open. When the rain picked up a few minutes later, that number jumped closer to 80%. It got me thinking it'd be cool to track this somehow, so I built a website! I am taking a sidewalk livestream, feeding it into a YOLO model for people tracking, then sending a frame of each detected person to Gemini 2.0 Flash, which returns structured JSON about each person's clothing and if they're holding an umbrella. I also had fun making the site look like a TV weather channel. I showed some friends this project and someone mentioned how the legendary Tasks xkcd comic ( https://xkcd.com/1425 ) is out of date now. If you want to check whether a photo has birds in it (or if someone is holding an umbrella), you can just ask an inexpensive vision model for JSON.

This is a personal project I've been working on for a long time now. I stumbled upon the color quantization problem while doing something related for work. I then found an interesting paper for which I could find no implementations online, and the thing went from "let's implement this paper" to getting pretty obsessed with the whole thing. It's at an early, eaaaarly stage. There's a lot of work to be done, and it's a memory hog, but generally speaking works quite well, and the output is for the most part very high quality, so I'm happy to share it as beta.

I work on R00M 101, a Reddit-based OSINT profiler. While building it, I realized most open-source intelligence (OSINT) tools are scattered across GitHub, outdated blog posts, or random Discords. So I put together a public-facing directory of 100+ OSINT tools used by analysts, journalists, and security folks, free, filterable, and categorized by risk, platform, and use case. The idea was to make something useful and no-friction. Built with static HTML + SQL backend + a lot of caffeine. Would love feedback on how to improve the UX or tool curation. If anyone wants to contribute tools or help moderate, that’s also welcome. Thanks!

Show HN: A free AI risk assessment tool for LLM applications
20 by percyding99 | 4 comments on Hacker News.
We’ve built an AI risk assessment tool designed specifically for GenAI/LLM applications. It's still early, but we’d love your feedback. Here’s what it does: 1. it performs comprehensive AI risk assessments by analyzing your codebase against different AI regulation/framework or even internal policies. It identifies potential issues and suggests fixes directly through one click PRs. 2. the first framework the platform supports is OWASP Top 10 for LLM Applications 2025, upcoming framework will be ISO 42001 as well as custom policy documents. 3. we're a small, early stage team, so the free tier offers 5 assessments per user. If you need more, just reach out, happy to help. 4. sign in via github is required. We request read access to scan code and write access to open PRs for fix suggestions. 5. we are looking for design partners to collaborate with us. If you are looking to build compliance-by-design AI products, we'd love to chat. product url: https://ift.tt/BoAd6YW we'd really appreciate feedback on: - what you like - what you don't like - what do you want to see for the next major feature - bugs - any other feedback feel free to comment here or reach out directly: email: percyding@gettavo.com, linkedin: https://ift.tt/6VuHM83

It identifies potential issues and suggests fixes directly through one click PRs. 2. the first framework the platform supports is OWASP Top 10 for LLM Applications 2025, upcoming framework will be ISO 42001 as well as custom policy documents. 3. we're a small, early stage team, so the free tier offers 5 assessments per user. If you need more, just reach out, happy to help. 4. sign in via github is required. We request read access to scan code and write access to open PRs for fix suggestions. 5. we are looking for design partners to collaborate with us. If you are looking to build compliance-by-design AI products, we'd love to chat. product url: https://ift.tt/BoAd6YW we'd really appreciate feedback on: - what you like - what you don't like - what do you want to see for the next major feature - bugs - any other feedback feel free to comment here or reach out directly: email: percyding@gettavo.com, linkedin: https://ift.tt/6VuHM83

New top story on Hacker News: Ask HN: What will tech employment look like in 10 years?
Ask HN: What will tech employment look like in 10 years?
16 by ipnon | 17 comments on Hacker News.
What jobs will become prevalent? Which will become scarce? I do not predict the elimination of the humble coder, but the covid hiring wave has come and gone, and Big Tech for the most part successfully minimized the workforces of those who were hired in the covid wave: frontend, backend and fullstack engineers. The patterns of code required for these positions have been successfully recognized by the LLMs I think, and for many cases a single staff engineer with experience and a trusty LLM is similarly productive as a team of 2-4 junior engineers led by a senior engineer was only a short 5 years ago. I do not expect much expansion in this "traditional" web development (these positions have really only existed in modern form for about 20 years, roughly when Rails was first released). Many such as Amjad Masad and Beff Jezos are of the opinion that for those who would have taken these positions before, the options are to either drill down the stack towards the bare metal, by reason of relative difficulty of embedded engineering, and that one struggles to imagine high-stakes software such as in a SpaceX rocket, Boeing airplane, or Anduril drone relying primarily on vibe-coded slop hastily LGTM'd into production. So the kind of software that requires large amounts of formal, simulated, or physical verification seems to still be necessary, but this is much more difficult to write than a webpage. Expansions in the labor market for those writing C, C++, Rust in the context of operating systems, embedded systems, microcontrollers, drivers, and so forth seems likely. The other option seems to be to leave the stack entirely, and leverage small teams to create niche and targeted applications for small segments of users. There has been some success in this area as well, but requires a much broader skillset than simply being an expert programmer and understanding some computer science. The options seem to be either to start reading Bjarne Stroustrup or Peter Thiel. But the skill ceiling for either path is fairly high, and for the short term I predict a sustained contraction in the software engineering labor market, while people adapt their educations and long-term career goals. Headcounts at FAANG I don't see recovering soon if ever. This has broader implications for a traditional startup route where one earned their stripes at FAANG before launching their own venture, but I digress ...

New top story on Hacker News: Show HN: AnuDB– Backed on RocksDB, 279x Faster Than SQLite in Parallel Workloads
Show HN: AnuDB– Backed on RocksDB, 279x Faster Than SQLite in Parallel Workloads
5 by hashmak_jsn | 0 comments on Hacker News.
We recently benchmarked AnuDB, a lightweight embedded database built on top of RocksDB, against SQLite on a Raspberry Pi. The performance difference, especially for parallel operations, was dramatic. GitHub Links: AnuDBBenchmark: https://ift.tt/sxS5Zvc AnuDB (Core): https://ift.tt/UkIPNnF Why Compare AnuDB and SQLite? SQLite is excellent for many embedded use cases — it’s simple, battle-tested, and extremely reliable. But it doesn't scale well when parallelism or concurrent writes are required. AnuDB, built over RocksDB, offers better concurrency out of the box. We wanted to measure the practical differences using real benchmarks on a Raspberry Pi. Benchmark Setup Platform: Raspberry Pi 2 (ARMv7) Benchmarked operations: Insert, Query, Update, Delete, Parallel AnuDB uses RocksDB and MsgPack serialization SQLite uses raw data, with WAL mode enabled for fairness Key Results Insert: AnuDB: 448 ops/sec SQLite: 838 ops/sec Query: AnuDB: 54 ops/sec SQLite: 30 ops/sec Update: AnuDB: 408 ops/sec SQLite: 600 ops/sec Delete: AnuDB: 555 ops/sec SQLite: 1942 ops/sec Parallel (10 threads): AnuDB: 412 ops/sec SQLite: 1.4 ops/sec (!) In the parallel case, AnuDB was over 279x faster than SQLite. Why the Huge Parallel Difference? SQLite, even with WAL mode, uses global database-level locks. It’s not designed for high-concurrency scenarios. RocksDB (used in AnuDB) supports: Fine-grained locking Concurrent readers/writers Better parallelism using LSM-tree architecture This explains why AnuDB significantly outperforms SQLite under threaded workloads. Try It Yourself Clone the repo: git clone https://ift.tt/sxS5Zvc cd AnuDBBenchmark ./build.sh /path/to/AnuDB /path/to/sqlite ./benchmark Results are saved to benchmark_results.csv. When to Use AnuDB Use AnuDB if: You need embedded storage with high concurrency You’re dealing with telemetry, sensor data, or parallel workloads You want something lightweight and faster than SQLite under load Stick with SQLite if: You need SQL compatibility You value mature ecosystem/tooling Feedback Welcome This is an early experiment. We’re actively developing AnuDB and would love feedback: Is our benchmark fair? Where could we optimize further? Would this be useful in your embedded project?

Show HN: ProcASM – A general purpose, visual programming lanugage
5 by Temdog007 | 1 comments on Hacker News.
I've been working as a software engineer since 2016. I've always had side projects that I would work on outside of my job. At first, it was just web games. But in 2021, I took an interest in programming languages and started making my own. When I got laid off from my job in late 2023 (budget cuts according to my employer), I decided to focus on becoming an independent developer and being able to monetize my own software. Since I was working on programming languages, my plan was to make a commercial grade programming language. Monetizing it would be difficult since there are so many free and open source programming languages out there. The only way I could think to stand out was to make something that hasn't been made before. General purpose programming languages DO exist; Visual programming languages DO exist. As far as I know, general purpose, visual programming languages DO NOT exist. So, that is what I decided to create. I wrote a blog on my website < https://temware.site/html/blogs/procasm_justification.html > talking about how ProcASM works and some justifications on why developers and companies would consider using it. There is documentation < https://procasm.temware.site/documentation.html > describing ProcASM's concepts in more detail. And, there is a manual < https://procasm.temware.site/manual.html > that describes how to use application itself. I have examples on the website < https://procasm.temware.site/procedure_view.html > showcasing how procedures are displayed in ProcASM. The images on that page are procedures, created in ProcASM, that were exported to SVG files from ProcASM. You can try out ProcASM for free in your browser here: < https://procasm.temware.site/demo.html > If you just want to see examples in ProcASM, use the links below to load projects in the demo. Sample Project: < https://procasm.temware.site/demo.html?sampleProject=https%3... > Execute the Procedures: *Fibonacci*, *Test: Fizz Buzz*, and *Guess Number* to get an idea on how ProcASM works. Network Project: < https://procasm.temware.site/demo.html?sampleProject=https%3... > This project contains examples of TCP clients and servers. If your using the browser version, you can load the project and view the procedures. However, you cannot execute any of the procedures in this project since they rely on native dynamic libraries which can't be executed in the browser. If you are using the desktop version, you can execute the procedures: Test TCP Client, Test TCP Server, and Test HTTP Server. This page < https://procasm.temware.site/getting_started.html?show=netwo... > can help you with compiling a dynamic library on you machine. Support Forum Project: < https://procasm.temware.site/demo.html?sampleProject=https%3... > To ensure that ProcASM was suitable for software development, I decided to create something non-trivial with it; the back-end for the support forum < https://forum-procasm.temware.site >. The project was transpiled to C code using ProcASM (available only for the desktop versions). Then, that C code was compiled on a FreeBSD machine to generate an executable. That executable is running on a FreeBSD server. The *Server* procedure is the *main* procedure for the application. The dynamic library is not available. So, you can only view the procedures in this project.

Show HN: CodeCafé – A real-time collaborative code editor in the browser
8 by mrktsm__ | 0 comments on Hacker News.
Hey guys! I’ve been working on a web app called CodeCafé—a collaborative, browser-based code editor inspired by VS Code and Replit, but with no downloads, no sign-up, and zero setup. You just open the link and start coding—together. The frontend is built with React and TypeScript, and the backend runs on Java with Spring Boot, which handles real-time editing via WebSockets. For syncing changes, I’m using Redis along with a custom Operational Transformation system (no third-party libraries!!!). The idea came after I found out a local summer school was teaching coding using Google Docs (yes, really). Google Docs is simple and free, but I wanted something that could actually be used for writing and running real code—without the need for any sign-ups or complex setups. That’s how CodeCafé came to life. Right now, the app doesn’t store files anywhere, and you can’t export your work. That’s one of the key features I’m working on currently. If you like what you see, feel free to star the repo to support the project!! Check it out and let me know what you think! GitHub: github.com/mrktsm/codecafe Web App: codecafe.app

New top story on Hacker News: Ask HN: Is there hope for Microsoft 365 support?
Ask HN: Is there hope for Microsoft 365 support?
18 by joaopbnogueira | 6 comments on Hacker News.
The company I work for (25friday.com) has been hit with what seems to be a keyword blacklist on Microsoft 365 email. In short, if we send out any email to clients using Microsoft 365 as their email provider containing the textual content "25friday.com" anywhere on the email subject, body or readable attachment (e.g. pdf) the emails fall on a "blackhole" and are neither bounced nor reaching the recipient (they are not in spam or quarantine either). As you might imagine this is a huge problem for us as email is our primary means of communication with our clients and we need to be careful to never include any mention of our domain in any email we send to them. For recipients using personal Outlook emails, the emails are received and sent to spam with a spam score of 9 (maximum score). We've reached Microsoft support and they seem as clueless as we are. They have no idea why this is happening and they are unable to provide any information or progress on the ongoing issue. This has been going on for about a month now. A few things we have tried: - We have checked our SPF, DKIM, and DMARC records and they are all set up correctly and passing. - We have checked our email sending reputation and it is good as far as we can tell. - We have tried sending emails from different email addresses and domains, but the issue persists. - We have setup our own Microsoft 365 account to be able to submit false-positive reports on the security portal, but the submissions disappear into the void and we never receive any feedback. - We have tried some deliverability testing tools and they all report that our emails are being blocked by Microsoft 365, but not by any other email providers. - We are not on any known/public blacklists Note that we are using Google Workspaces, but that does not seem to be the issue. The domain itself has been live since 2018 (since the company was founded) and we have never had any issues with email deliverability before. We don't send spam or unsolicited emails. The closest I could think of is a mailing list we have with about 300 subscribers containing mostly client emails but also some emails of people we invite to our events. We send out an approximately monthly newsletter to this list, but we have never had any complaints or issues with it before (we're using Pipedrive for that). Tangential but I believe that it might be related: if I set my website address as 25friday.com on my LinkedIn profile, the link gets overwritten to a LinkedIn error page. My guess is that since LinkedIn is owned by Microsoft, they are sharing the same blacklist. Any tips would be greatly appreciated. We're really affected by this and without any recourse to escalate this issue.
