Author: i19

Description: Hi HN, I am i19

I subscribe to many rss feeds, reading them is quite time-consuming, and some of which are not in my mother tongue, which makes reading them even more challenging. I need a way to quickly understand them without reading through every word.

I found a lot TLDR extensions is not working anymore, so i build my own TLDR, nothing fancy but it allows me to grasp the main points in my own language. It support English/Chineses/Japanese/Korean for now. Hope it can help other peoples who is in my situation too

3. Show HN: Compose2nix – NixOS and Docker Compose made easy

URL: https://github.com/aksiksi/compose2nix

Author: Cyph0n

Description: Hi!

compose2nix is a CLI tool that automatically converts your Docker Compose project into a NixOS configuration[1].

* Why does this even exist?

Well, NixOS is a Linux distro that is configured using Nix (the language). However, Compose adds a configuration layer on top that is opaque to Nix, which means you lose out on some of the “magic” of NixOS. compose2nix solves this by “lifting” Compose functionality into native Nix/NixOS constructs, which results in a more native integration with NixOS.

In addition, this tool unlocks two primary use-cases:

1. You can run existing non-trivial applications - e.g., Immich - without worrying if they’re natively packaged for NixOS.

2. You can bring your existing Compose stack over to NixOS and run it as-is without having to rewrite it in Nix. The auto-generated config can either act as a starting point, or you can keep your Compose file as the source of truth and re-generate it as you go.

* How does it work?

compose2nix maps Compose constructs into systemd services that run native Docker/Podman commands. Under the hood, the tool utilizes the same Compose library[2] used by the Docker CLI, so you also get Compose syntax checking “for free”. In a way, it’s a thin re-implementation of the Docker Compose CLI. One thing to point out is that compose2nix aims to natively support both Podman and Docker as container runtimes.

The README has a bit more detail. There’s also a (somewhat rambly) video that explains what the project is about and includes a short demo of the tool: https://www.youtube.com/watch?v=hCAFyzJ81Pg

Oh, and please feel free to shoot me any questions or feedback (good or bad)!

Author: gurgeous

Description: I find smoke detectors pretty interesting, especially after debugging many false alarms in the middle of the night. There isn’t much detail out there due to the ongoing enshittification of the internet. Maybe this will help? Feedback pls!

Surprising quantity of tech used, definitely overkill. Vite/Vue/Tailwind/Daisyui hosted on Vercel behind Cloudflare. We used Markdown-it for the content with simple custom stuff to mixin Vue components. On the data side, some Amazon crawling along with a lot of grunt work and proofreading. Httpdisk for crawl caching. Rembg for image background removal. Oh, and we also use Asdf+Just+Direnv on the dev side. Really love Just and use it heavily all the time now.

A bit of interesting math for the CSS animation at the top. I learned you could combine two translateX() animations inside a single transform, which is key for that thing.

13. Show HN: The Playground App – mobile app specific for finding playgrounds

URL: #

Author: andsmi2

Description: Excited to see this release come out for http://www.bearswithapps.com — here are some highlights:

. My wife took over my small ‘indie dev’ app business as a non-tech CEO a few years ago as I needed to commit more time to “day-job’ efforts, this is her first major release using some great friends from Jaipur as the primary developer resource.

. I’ve done GIS/map development for over 10 years, including on the iPad and iPhone as well as web, this combines a lot of that experience to help get her dev team working and moving through what seems to be an ‘easy’ thing but has little nuances

. We are using (and attributing) Open Street Map data, which is an interesting challenge, specifically loading ‘on demand’ for the user to our own database and then ‘tweaking’ for better appearance

. There were a few other similar apps out and at least one came out while we were in development, but I think we have some good features coming and this also allowed her to build a ‘platform’ for map apps she can reuse for other similar apps (other categories, verticals, etc.)

. Why not just use google maps? Because google maps isn’t great at finding specific types of things. Apple just “sherlocked” AllTrails because their maps weren’t great at finding trails. This runs the risk of being put into a larger map platform eventually — but there are lots of ‘little things’ that need some specific mapping (playgrounds is just the start) that the big platforms don’t need to focus on. Yes you can find playgrounds in google maps but it isn’t conducive to exploring them — and with future features like sort by ‘accessible swings’, etc. it could be even harder for a generic wide brush kind of app to compete with

. Android version? Working on it, it’s react native so it is in process and should be soon

. Revenue? we are trying for ads, but think there is room for ‘one big sponser’ that could fund the app and have it’s name plastered all over it…

. bugs? At some point you have to pull the trigger and release… the team can handle rapid releases so we will fix things as fast as we get them there, but there wasn’t a reason to sit on the app any longer

Wow…that’s my brain dump for right now, please ask questions I’d love to answer.

15. Show HN: FFmpeg-over-IP – Connect to remote FFmpeg servers

URL: https://github.com/steelbrain/ffmpeg-over-ip

Author: steelbrain

Description: Dear HN,

I’m excited to show case a personal project. It has helped me quite a bit with my home lab, I hope it can help you with yours too! ffmpeg-over-ip has two components, a server and a client. You can run the server in an environment with access to a GPU and a locally installed version of ffmpeg, the client only needs network access to the server and no GPU or ffmpeg locally.

Both and client and the server need a shared filesystem for this to work (so the server can write output to it, and client can read from it). In my usecase, smb works well if your (GPU) server is a windows machine, nfs works really well for linux setups.

This utility can be useful in a number of scenarios:

- You find passing through a (v)GPU to your virtual machines complicated

- You want to use the same GPU for ffmpeg in multiple virtual machines

- Your server has a weak GPU so you want to use the GPU from your gaming machine

- Your GPU drivers in one OS are not as good as another (AMD RX6400 never worked for me in linux, but did so in windows)

I’ve posted some instructions in the Github package README, please let me know if they are unclear in any way and I’ll try to help!

Description: Hey HN!

I’ve been in the affiliate marketing space for quite some time, and one major pain point I’ve always faced is the inefficiency of managing affiliate links from multiple networks. You end up switching tabs endlessly, using different tools, and the process is cumbersome, often leading to lost commissions and wasted time.

So I built AffEasy: a tool that consolidates affiliate link management across all major networks into a single dashboard.

23. Show HN: Build a Kafka broker from scratch, in any language

URL: #

Author: ryangg

Description: Hey everyone, Ryan here from CodeCrafters (https://codecrafters.io).

I’m excited to share our latest challenge: Build your own Kafka.

In this challenge, you’ll create a Kafka broker that can read Kafka log files and respond to requests using the Kafka wire protocol. We’ve broken the project down into 18 bite-sized stages, starting with simpler tasks like implementing the Kafka protocol and progressively getting more complex. You can check out the stage breakdown here: https://app.codecrafters.io/courses/kafka/overview.

Like our other challenges, we’ll continue adding extensions to this one to cover more Kafka features like transactions, replication, and more.

One of the toughest parts of building this challenge was reverse-engineering the Kafka protocol—it’s notoriously under-documented, which our early testers also pointed out.

To make it easier to study Kafka’s message formats, we built binspec.org, an interactive tool that lets you explore protocol formats byte by byte. Think of it like Wireshark’s analyzer, but designed for understanding protocols in detail. It visually breaks down message structures, showing each byte in context with helpful annotations. For instance, when examining a Kafka request, binspec highlights different fields—like message size or request headers—and explains their role in the protocol. Here’s an example visualizer for a Kafka request: https://binspec.org/kafka-api-versions-request-v4

While working through this challenge, you’ll get a deep understanding of how Kafka works under the hood, but you’ll also build mastery in your language of choice. We currently support five languages—including Rust, Python, and Go—and like with our other challenges, we’ll expand this based on demand.

We’re keeping this challenge free in beta for a few weeks to gather feedback, so feel free to dive in and let us know what you think. You can start building here: https://app.codecrafters.io/courses/kafka/overview. Grateful for all feedback!

24. Show HN: Chess Puzzle Bot – Puzzles vs. Stockfish

URL: https://www.chesspuzzlebot.com/

Author: 1bit_e

Description: I made a website where you can play chess puzzles against Stockfish!

When playing puzzles, neither Lichess nor Chess.com will accept a wrong move, which in my opinion spoils the resolution of the puzzle since only correct moves allow you to keep playing.

So, I had the idea for a website where you can play chess puzzles, but if you make the wrong move, the puzzle turns into a game against Stockfish. This opens the door to either find alternative solutions or fail miserably (at some point you realize you are not following the puzzle any more). I think its a more engaging way to play puzzles!

This is my first website, don’t expect every div to be correctly centered. The mobile version may not be as polished but is still playable.

26. Show HN: PII Detective, Leveraging LLMs for Cost-Effective PII Detection

URL: https://github.com/kpolley/PIIDetective

Author: kpolls

Description: PII Detective is a web application designed to identify, classify, and protect Personally Identifiable Information (PII) in data platforms such as BigQuery and Snowflake. It leverages LLMs to identify PII column names, and with human-in-the-loop validation, uses Dynamic Data Masking Policies to easily enforce Access Control Limits (ACLs) while minimizing user friction.

For comparison, GCP has a “Sensitive Data Protection” service which promises similar functionality, but it can become extremely costly since it runs hundreds of regex queries on the entire contents of the table. For comparison, PII Detective only uses table metadata such as table and columns names, so you can detect PII in thousands of tables for less than $5 of OpenAI credits!

More info and a demo in the github link. Cheers!

28. Show HN: One – A new React framework unifying web, native and local-first

URL: https://onestack.dev

Author: nwienert

Description: Hey HN, I’m Nate, the creator of Tamagui.

One is a React framework that does two things differently in hopes of simplifying how we build websites and apps:

1. It unifies React Native and React web with typed file system routing by making Vite able to serve RN. This lets you share (or diverge) your code in a simpler way for cross-platform apps.

2. We’ve partnered with Zero (https://zerosync.dev) to make local-first work well. We’ve been building a solution in One that makes Zero supporting server rendering, without waterfalls, and with seamless server/client handoff.

---

Honestly - I’m a bit hesitant to post One here.

HN has really soured on frontend/frameworks. And I get it. We’ve collectively complicated the hell out of things.

That’s why I decided to build One. I loved Rails, it made me as a young developer able to finally realize way more ambitious projects than I’d ever done before. I also liked the promise (not implementation) of Meteor - it felt like the clear future, I guess just a bit too early (and a bit too scope-creeped).

I worked at Uniswap and built Tamagui and so spent a lot of time building cross-platform apps that share code. Uniswap is built on Tamagui and I think proves you can make really high quality UX while sharing a lot of code - but it’s insanely hard and requires a huge team. My goal with One is to make what is now possible but hard dramatically easier.

And I think the path to there goes through local-first, because it makes building super responsive apps much, much simpler, and Zero is the first library to actually pull it off in a way that doesn’t bloat your bundle or have very limiting constraints.

I happened to live down the street from Aaron, one of the founders of Zero, in our tiny town in Hawaii. We talked a lot about Zero over the last couple years, and I found it really admirable how he consistently chose the “harder but better” path in building it. It really shaped into something incredible, and that convinced me to actually launch One, which at the time was more of an experiment.

I can see a lot of potential criticism - do we need yet another framework, this is too shiny and vaporware-y, this is just more complexity and abstraction, etc. Happy to respond to those comments if they come.

I’m just building out something that I’ve been wanting for a long time. Opinionated enough to let me move fast like Rails, but leaning on the great work of team Zero so that we don’t end up with the scope creep of Meteor. And honestly, it’s just really fun to hack on.

URL: https://github.com/ravachol/kew

Author: ravachol

Description: Hi HN,

I created kew, a music player for the Linux terminal.

This started when I asked myself: what if I could just type something like “play nirvana” in the terminal and have the rest taken care of automatically? That got the ball rolling and I kept adding stuff: covers in ascii and then as sixel images, a playlist view, a visualizer, a library view and finally search.

While kew can be used as a commandline tool, it has evolved into a TUI app.

Here are some example commands:

kew nirvana # Plays all of your Nirvana songs, shuffled

kew nevermind # Plays the “Nevermind” album in order

kew spirit # Plays “Smells Like Teen Spirit”

kew all # Plays all your music, shuffled

kew albums # Plays one album after the other in random order

It works best when your music library is organized like this: Artist/Album(s)/Track(s)

kew is written in C and licensed under GPLv2.

URL: #

Author: earcar

Description: I’ve just released MQTT Alive Daemon v0.2.0, a lightweight go daemon for integrating computer status and custom commands with Home Assistant via MQTT. I built this because I wanted to know when my computers were on and I was at my desk, and existing solutions weren’t responsive enough or were too resource-intensive.

Key features:

* Reports when the PC is on

* Reports the result of any custom command

* Seamless integration with Home Assistant

* Support for launchd and systemd (new in v0.2.0)

In my setup, it’s helped me save energy by automatically managing 3 speakers, a mixer, a monitor, lights, and various USB music peripherals when I’m actually at my desk using them.

I’m interested in hearing thoughts from the HN community. How could this be expanded or improved? What other use cases do you see for this kind of lightweight integration between computers and home automation?

43. Show HN: I made a free iOS Lorcana cards price scanner

URL: https://apps.apple.com/us/app/tcg-card-price-scanner/id6720749819

Author: Nyoxide

Description: Hey everyone,

I’m excited to share a new app I’ve been working on for the Lorcana TCG community! It is designed to help you get real-time market prices and detailed info about your Lorcana cards quickly and easily.

Here’s how it works:

Scan your card: Just point your phone’s camera at the card and in 1-3 seconds, the app will pull up details like the card’s market prices, name, set, edition, and rarity. • Track prices: Instantly see the card’s estimated value so you can make informed decisions about buying, selling, or trading. • Browse card sets: The app lets you explore all the available cards. • Track scan history: Keep a history of all the cards you’ve scanned.

The app is 100% free, with no paywalls or ads. It’s just a simple tool designed to help Lorcana players and collectors keep track of their cards and prices easily.

I’d love your feedback and suggestions!

Thanks.

45. Show HN: apw – A CLI for Apple Passwords

URL: https://github.com/bendews/apw

Author: bendews

Description: Hey HN,

I built apw as a simple CLI tool to manage Apple passwords, aiming to move away from third-party solutions. I have been hesitant to release it since Apple’s major updates to password management this year left me unsure if it would still be relevant or functional.

However, after using it consistently on macOS 15, I can confidently say it still works great! While Apple’s Passwords.app has made significant strides, I find apw much more convenient for integrating with other tools like Raycast.

Would love your feedback!

URL: https://www.tryeloquent.com/

Author: simssousa15

Description: Hey everyone,

Long story short, I was writing my master’s thesis and felt like none of the writing assistants did what I wanted, so I decided to create my own. The goal for it was to be a simple easy-to-use tool that uses LLMs to assist you in your reading and writing work.

Would love to get your feedback on it.

Cheers

50. Show HN: HackYourNews.com v2

URL: #

Author: ukuina

Description: One year after I published https://HackYourNews.com, I’ve rewritten it to be fully client-side and added support for a few more news sources via RSS feeds.

Though HackYourNews.com v1 had a great response on HN [1] and consistently had ~2k weekly unique visitors, I couldn’t figure out how to sustain the site, and I didn’t want to gate access to it.

There were also many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper auto-detected dark mode, mobile device support, and bulleted summaries.

This rewrite is the result.

The browser reads the contents of destination pages via a CORS proxy [2], distills the raw HTML down to page content, and uses the excellent Puter [3] to call gpt-4o-mini for chunked summarization and title dehyping.

Overall, the rewrite is slower because the summarization is on-demand, but the value I get from the summaries has not reduced, so I think it’s a win. Given the latency reductions in the last year for frontier models, this approach should scale nicely.

The source is unminified and easy to read. Hope you find it useful!
