2. Show HN: Pretty-print your chess games using Prettier
URL: https://github.com/gmasclet/prettier-plugin-pgn
Author: gmasclet
Description: Hi,
As an enthusiast chess player, I like to manage my games and my opening repertoire as a set of PGN files stored in a Git repository (PGN is a text file format for recording chess games). So I wanted a way to pretty-print PGN files using a CLI and integrating in my editor.
Today, it looks like most people use GUI-based software. So I decided to create a Prettier plugin that formats PGN files. Prettier is a well-known pretty-printer in the Node.js ecosystem, used to ensure consistent source code formatting in software projects. One upside of implementing this PGN formatter as a Prettier plugin is that it benefits from its editor integration.
The plugin is currently near complete, even if the project is still at an early stage. It's usable, even if there might be some bugs.
Hope you find this useful. Comments and ideas are welcome. Have a nice weekend.

3. Show HN: I created a PoC for live descriptions of the surroundings for the blind
URL: https://github.com/o40/seesay
Author: o40
Description: The difference in cost between products that are developed as accessibility tools compared to consumer products is huge. One example is camera glasses where the accessibility product costs ~$3000 (Envision Glasses), and the consumer product costs ~$300 (Ray-Ban Meta).
In this case the Ray-Ban Meta is getting accessibility features. The functionality is promising according to reviews, but requires the user to say "Hey meta what am I looking at" every time a scene is to be described. The battery life seem underwhelming as well.
It would be nice to have an cheap and open source alternative to the currently available products, where the user gets fed information rather than continuously requesting it. This is where I got interested to see if I could create a solution using an ESP32 WiFi camera, and learn some arduino development in the process.
I managed to create a solution where the camera connects to the phone "personal hotspot", and publishes an image every 7 seconds to an online server, which then uses the gpt-4o-mini model to describe the image and update a web page, that is read back to the user using voice synthesis. The latency for this is less than 2 seconds, and is generally faster.
I am happy with the result and learnt a lot, but I think I will pause this project for now. At least until some shiny new tech emerges (cheaper open source camera glasses).

4. Show HN: An SSH based utility to transfer pipes across machines – beam
URL: https://github.com/ksdme/beam
Author: ksdme9
Description: Hey HN,
At work, I was annoyed about having to download logs by writing them out to files and transferring them over to my local over HTTP (admittedly, this is because of a rather novel architectural situation).
So, I built a tool in Go that lets you pipe contents into an SSH server for sending and reading them out on another connection. You can also use this tool to transfer files. Just cat the file on the sender end and redirect the output of the receiver end to a file.
Please note that the transfer rate is heavily dependent on your connection and proximity to the public ssh.beam.camp host. This is because there is no simple way to auto connect to the closest host using a regular SSH client.
Hope you find beam useful. Have a nice weekend.

5. Show HN: WikiTimeline – AI-powered tool to visualize and compare timelines
URL: https://wiki-timeline.com
Author: StevenLee2024
Description: I built WikiTimeline because of my fascination with history and the desire to easily visualize and compare the lives of historical figures. The tool converts any Wikipedia article into an interactive timeline.
For example, I created a timeline of America's Founding Fathers and discovered some interesting patterns I hadn't noticed before:
Benjamin Franklin was significantly older than the other Founding Fathers. He was already 70 when the Declaration of Independence was signed, while Alexander Hamilton was only 21!
John Adams and Thomas Jefferson both died on July 4, 1826 – exactly 50 years after signing the Declaration of Independence. What are the odds?
The entire project was built by AI, timelines are generated by openAI, code are written by Cursor/Claude, although myself an developer, I didn't write a single line of code, sometimes I literally just prompted "make it prettier", then magic happens, a modern like UI appears! I think I had this idea in the past, but without AI, I probably won't really implement it. Try it out: https://wiki-timeline.com You can compare any Wikipedia pages. Just search and select multiple articles to create comparative timelines. Would love to hear your feedback and interesting historical patterns you discover!

I think I'm not the only one who thinks like that and that is why I've published "Is Generated" it's a community based Chrome Extensions where users can report, vote and block the content they suspect is AI-generated.
Together, we can take back control and make the internet a better place for authentic creators!

15. Show HN: Lightweight Llama3 Inference Engine – CUDA C
URL: https://github.com/abhisheknair10/Llama3.cu
Author: abhisheknair10
Description: Hey, recently I took inspiration from llama.cpp, ollama, and many other similar tools that enable inference of LLMs locally, and I just finished building a Llama inference engine for the 8B model in CUDA C.
I recently wanted to explore my newly founded interest in CUDA programming and my passion for machine learning. This project only makes use of the native CUDA runtime api and cuda_fp16. The inference takes place in fp16, so it requires around 17-18GB of VRAM (~16GB for model params and some more for intermediary caches).
It doesn’t use cuBLAS or any similar libraries since I wanted to be exposed to the least amount of abstraction. Hence, it isn’t as optimized as a cuBLAS implementation or other inference engines like the ones that inspired the project.
## A brief overview of the implementation
I used CUDA C. It reads a .safetensor file of the model that you can pull from HuggingFace. The actual kernels are fairly straightforward for normalizations, skip connections, RoPE, and activation functions (SiLU).
For GEMM, I got as far as implementing tiled matrix multiplication with vectorized retrieval for each thread. The GEMM kernel is also written in such a way that the second matrix is not required to be pre-transposed while still achieving coalesced memory access to HBM.
Feel free to have a look at the project repo and try it out if you’re interested. If you like what you see, feel free to star the repo too!
I highly appreciate any feedback, good or constructive.

17. Show HN: ArXiv papers, explained like you're five
URL: https://elixiv.org/abs/1706.03762
Author: luisgnet
Description: Hey everyone,
A few weeks ago, I was struggling to make my way through a somewhat dry arXiv paper, and over the holiday break, decided to tackle a quick prototype / idea I had for a website where you:
1. Can open any arXiv document by modifying its arXiv URL (arxiv.org/... -> elixiv.org/...)
2. Can scroll through the document and click a sentence
3. See the sentence on the sidebar, explained like you're 5 (or 3, or 10, ... or 0)
4. Can mark a sentence as "understood" to keep going going through the document
I think I ended up with a prototype that's actually pretty fun to play with, leading to some useful summaries that make reading an arxiv paper feel much more casual. (Or alternatively, you can get some pretty funny summaries if you set the age to 0 or 10).
The demo doc (linked) is completely free to play with, no login / signup required. Any other arxiv doc currently requires signing in with google and you'll get 3 free docs per month.

19. Show HN: Kachika – "Learning Japanese Through Life"
URL: https://apps.apple.com/us/app/kachika-smart-japanese-camera/id6739525442
Author: xcc3641
Description: I'm both a Japanese learner and an indie developer. Throughout my journey of learning Japanese (currently living in Japan), I've deeply felt the challenge of memorizing words — learning them only to forget, wanting to speak but finding myself tongue-tied.
Why I Made This As someone who relies heavily on visual memory, I understand the power of turning abstract concepts into visual forms. You know that feeling when you're walking around and spot something interesting — maybe a beautiful seasonal poster, a curious shop name, or even just a package design that catches your eye? Those little moments of curiosity that make you think "I wish I could remember these words!"... That was exactly my experience
This experience inspired a simple yet powerful idea: "Learn Japanese through life, live with Japanese" — and that became the heart and soul of this app: Kachika (カチカ).
Turn Your Daily Discoveries into Learning Moments Kachika helps you learn Japanese naturally through your everyday life:
Capture What You See Just snap a photo of anything interesting in your daily life
Instant Learning Words are detected automatically with native pronunciation
Your Personal Collection Build vocabulary that matters to you, all stored privately on device
Fun fact about the name "Kachika" (カチカ):
カチッ (the sound of taking a photo)
勝ち (kachi - victory/success)
か (ka - that soft Japanese particle that makes everything sound nicer!)
I Need Your Help! I'm looking for fellow Japanese learners who want to make learning more natural and meaningful. What features would help you capture and remember your daily Japanese encounters?
I hope this app can help fellow learners who share the same struggles, making Japanese learning a natural part of our daily lives!
Would love to hear your thoughts and suggestions from:
People studying Japanese at any level
Visual learners who prefer real-world context
Anyone who wants to learn Japanese through their daily experiences
Let's make Japanese learning a natural part of our everyday adventures! ありがとうございます！

20. Show HN: Drop-In Out-of-Distribution Data Detector
URL: https://github.com/DebarghaG/forte
Author: barthelomew
Description: Out-of-Distribution (OOD) detection is possibly the most important problem for safe and deployable ML, because it provides the first line of defense by preventing silent failures in critical ML systems; bounds AI capabilities by recognition of model knowledge; allows for safe fallback and enables human oversight when needed.
Forte takes a novel approach to OOD detection with several key advantages. It utilizes self-supervised representations to capture semantic features while incorporating manifold estimation to account for local topology. Care has been taken to minimize deployment overhead; by eliminating additional model training requirements. Furthermore, it requires no class labels, no exposure to OOD data during training, and no restrictions to architecture of predictive or generative models. We have demonstrated strong domain generalization – having tested it on detecting synthetic data, MRI images etc.

25. Show HN: ExtensionLister – A Web App to Discover and Analyze Chrome Extensions
URL: https://extensionlister.com
Author: eddguzzo
Description: Hi HN,
I’m excited to share ExtensionLister, a simple web app I built to make discovering Chrome Web Store extensions faster and easier.
The Chrome Web Store has thousands of extensions, but finding the right one can be tedious, especially if you want to compare extensions based on their popularity, ratings, or features. ExtensionLister solves this by letting you:
• Filter extensions based on metrics like the number of users, downloads, average ratings, and more.
• Sort the results to find hidden gems or analyze low-rated but highly-used extensions.
• Explore data visually in a clean, sortable table interface.
How it works:
• No signup or barriers; just head to the site and start filtering/sorting extensions.
• The data is updated periodically and sourced directly from the Chrome Web Store.
Here’s the link: https://extensionlister.com
Thanks for checking it out!

Author: jasonthorsness
Description: While writing, I loathe leaving my editor to edit images in some GUI. It's worse during the revision process, when the same image might need to be adjusted over and over as the article changes. So, to support https://www.jasonthorsness.com a few years ago I wrote https://github.com/jasonthorsness/tractor-loader.
Tractor Loader enables inline image transformation in JSX and MDX. For example, here is a crop from my MDX blog source:
Now my workflow is to dump raw photos from my camera into an article's source folder, then crop and edit them inline while writing the article. I only rarely need to use a separate GUI image editor for advanced stuff. More examples are at https://tractor-loader.vercel.app/.
I've used this for years now -- is there anything else like this that is more standardized? Could this be useful for other sites? Any suggestions?

I'm an amateur radio operator (VE7AJK) and a web developer. I recently launched https://hamradioprices.com, a price tracker for amateur radio gear. Think of it as a DekuDeals (https://www.dekudeals.com/) but specifically for hams.
The website currently only tracks radios, but I plan to expand it to include other equipment like antennas, tuners, and accessories as time goes on. My goal is to help other hams find the best prices for their gear and make more informed buying decisions.
I’d open to constructive feedback, especially from other hams.
Thanks for taking the time to check it out.

URL: https://open.spotify.com/episode/2boPAtWPoMKfs8G6lWtht4
Author: davidkarolyi
Description: Over Christmas break, I started tinkering with an idea, a simple experiment to pass the time. What if I could build an AI podcaster that reads 100 of the best business books, extracts the most interesting ideas, and turns them into short, actionable episodes?
It sounded fun, so I gave it a shot.
What I didn’t expect was how much it would blow my mind. This AI didn’t just regurgitate information—it captured the essence of each book with a clarity and focus that felt almost... human. Somehow, it managed to distill complex ideas into their simplest, most powerful forms. The kind of takeaways that stick with you, long after you’ve heard them.
I sat there, listening to the AI narrate its findings, and I couldn’t help but feel amazed... This was more than I thought I’d create in a weekend project. It captured a kind of value that felt almost too good to keep to myself.
So here it is: my AI podcaster experiment in action. And this is just the beginning—new episodes will be released every single week, diving deeper into the best ideas in entrepreneurship.

43. Show HN: Today we made public the product we've been building for last 8 months
URL: https://lorna.ai
Author: fttrack
Description: Hi, my name is Horia and while I’m usually a lurker, that changes today as the hard part of building a product begins.
In short, Lorna AI records your meetings, generates transcripts in any language and creates very very good personalized notes + has an AI chat/AI search feature that you can use to ask questions and get answers based on meeting data.
Soon, we’ll make available the Intelligence Hub feature we’ve been working on, with which users can run complex research and simulation tasks. e.g. “what will happen if I increase the price by 20% for customer X” or “what are the objectives that you identified for me, let’s do some research for each of them”
So far, the product has been received very good by the early adopters and their feedback was very encouraging.
Would love to get your input, feedback, ideas, advices. If you have any questions, let me know.
Have a nice weekend!

47. Show HN: IoT_devices, a narrow-waist, minimal IoT driver plugin system
URL: https://github.com/EternityForest/iot_devices
Author: eternityforest
Description: This library gives you a simple abstraction layers for simple IoT devices, to make different devices behave more consistently.
Basically, a device type gives a host a JSON schema for config, and a set of data points the host can subscribe to or set.
Data points are numbers, strings, objects, and binary data, with no device-specific types, just metadata flags.
Devices can declare their own sub devices, but other than that, most cheap consumer gear can be represented with just those types, and most everything else is out of scope.
Still pre-1.0, not 100% finalized, but I have not seen any reason to make a breaking change since pretty early in the project history, except for removing a few experimental features that should never have been there in the first place.
I'd love to know what you guys think or if there's anything I should change before 1.0!
