[Other] Show HN: Ambient light sensor control of keyboard and screen brightness in Linux I have always wanted cool features in Linux because I use it day to day as my OS. I have always wanted to implement this feature and do it properly: one that automatically adjusts keyboard and LCD backlights using data from the Ambient Light Sensor.<p>I enjoy low-level programming a lot. I delved into writing this program in C. It came out well and worked seamlessly on my device. Currently, it only works for keyboard lights. I designed it in a way that the support for LCD will come in seamlessly in the future.<p>But, in the real world, people have different kinds of devices. And I made sure to follow the iio implementation on the kernel through sysfs. I would like feedback. :)

[Other] Lower transaction fees with Arbitrum-powered payments What We Do: We're building a payment gateway that bridges the gap between Web2 and Web3, powered by Arbitrum blockchain technology. The Problem We Solve: Traditional payment processors charge 2-3%+ per transaction. For small businesses operating on tight margins, these fees add up quickly. By utilizing blockchain technology, we're cutting these costs dramatically without requiring businesses or customers to understand crypto.

[Code Quality] Show HN: Duper – The Format That's Super An MIT-licensed human-friendly extension of JSON with quality-of-life improvements (comments, trailing commas, unquoted keys), extra types (tuples, bytes, raw strings), and semantic identifiers (think type annotations).<p>Built in Rust, with bindings for Python and WebAssembly, as well as syntax highlighting in VSCode. I made it for those like me who hand-edit JSONs and want a breath of fresh air.<p>It&#x27;s at a good enough point that I felt like sharing it, but there&#x27;s still plenty I wanna work on! Namely, I want to add (real) Node support, make a proper LSP with auto-formatting, and get it out there before I start thinking about stabilization.

[Testing] Show HN: KeyLeak Detector – Scan websites for exposed API keys and secrets I built this after seeing multiple teams accidentally ship API keys in their frontend code.<p>The problem: Modern web development moves fast. You&#x27;re vibe-coding, shipping features, and suddenly your AWS keys are sitting in a &lt;script&gt; tag visible to anyone who opens DevTools. I&#x27;ve personally witnessed this happen to at least 3-4 production apps in the past year alone.<p>KeyLeak Detector runs through your site (headless browser + network interception) and checks for 50+ types of leaked secrets: AWS&#x2F;Google keys, Stripe tokens, database connection strings, LLM API keys (OpenAI, Claude, etc.), JWT tokens, and more.<p>It&#x27;s not perfect, there are false positives but it&#x27;s caught real issues in my own projects. Think of it as a quick sanity check before you ship.<p>Use case: Run it on staging before deploying, or audit your existing sites. Takes ~30 seconds per page.<p>MIT licensed, for authorized testing only.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;Amal-David&#x2F;keyleak-detector" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Amal-David&#x2F;keyleak-detector</a>

[Other] Show HN: Micro-RLE ≤264-byte compression for UART/MCU logs, zero RAM growth I needed to stuff twice the telemetry through the same 115 kbaud line on a Cortex-M0+ that only had 8 kB flash left.<p>Micro-RLE is the smallest drop-in I could come up with: 264 B of Thumb code, 36 B of state, no malloc, worst-case 14 cycles&#x2F;byte and still lossless for every 8-bit pattern.<p>On the usual sensor streams (ADC, IMU, GPS) it’s 33-70 % smaller than raw output and boots in &lt; 600 µs, so you can fire-and-forget from main() before the PLL even locks.<p>Repo is a single .c file and a 3-function API—replace the weak emit() hook with your UART &#x2F; DMA &#x2F; ring-buffer and you’re done.<p>Size proof: arm-none-eabi-size micro_rle.o text data bss 264 0 36<p>MIT licensed, link in the repo. Happy to hear where else this fits!
