Show HN: Git-Add–Interactive with Enhancements
I created a replacement for the perl git-add--interactive that adds a few enhancements:<p>- S to automatically split all hunks<p>- G to set a global filter on hunks to show<p>- A to automatically accept all hunks (after auto-splitting and global filter are applied)
Show HN: Donut Browser, a Browser Orchestrator
Hi HN,<p>I'm excited to share my open source project, a browser orchestrator. It's purpose is to make it easy to manage many browser profiles on one system. Currently it only works on MacOS, but since I've built it using Tauri (which is a Rust backend and TypeScript frontend), I expect to add Linux and Windows support in the future.<p>I've built it primarily for myself as I use a lot of browsers and having an easy way to manage all of my profiles would make (have made, actually) my dock less cluttered haha. Also, part of why I built it is because as someone who doesn't really care about anti-detect features (which I might support in the future), I don't understand how they cost so much for a very limited number of profiles in pretty much all anti-detect browsers. I feel like a lot of people feel the same and will cover their use cases with my free tool.<p>If you try it, please share your feedback! I haven't seen any open source projects like this and want to learn more about how people might use it.
Show HN: W++ – A Python-style scripting language for .NET with NuGet support
Hey HN<p>I’ve been building *W++*, a scripting language that looks like Python but runs on the .NET runtime. It started as a fun side project, but it evolved into something surprisingly powerful — and potentially useful:<p>Key Features:<p>- Python-style syntax with semicolon-based simplicity<p>- Compiles to .NET IL with experimental JIT support<p>- Can run interpreted or compiled<p>- Built-in CLI for managing projects, running, and building<p>- Supports importing NuGet packages and converts them to .ingot modules automatically
- MIT licensed and fully open-source<p>You can even do things like:<p><pre><code> wpp
import Newtonsoft.Json
let person = new JObject()
person["name"] = "Alice"
print person["name"];
Use Cases:</code></pre>
Game scripting (Unity, OpenTK support in progress)<p>Education (gentle intro to .NET without C# syntax)<p>Blazor scripting<p>Embeddable scripting engine for .NET apps<p>GitHub:
<a href="https://github.com/sinisterMage/WPlusPlus">https://github.com/sinisterMage/WPlusPlus</a><p>I’d love feedback, ideas, and thoughts.
Thanks for reading — and if you’ve ever said “I wish Python ran on .NET,” this might be for you.

Show HN: AI Peer Reviewer – Multiagent system for scientific manuscript analysis
After waiting 8 months for a journal response or two months for co-author feedback that consisted of "looks good" and a single comma change, we built an AI-powered peer review system that helps researchers improve their manuscripts rapidly before submission.<p>The system uses multiple specialized agents to analyze different aspects of scientific papers, from methodology to writing quality.<p>Key features: 24 specialized agents analyzing sections, scientific rigor, and writing quality // Detailed feedback with actionable recommendations. // PDF report generation. // Support for custom review criteria and target journals.<p>Two ways to use it:<p>1. Cloud version (free during testing):
<a href="https://www.rigorous.company" rel="nofollow">https://www.rigorous.company</a>
- Upload your manuscript
- Get a comprehensive PDF report within 1–2 working days
- No setup required<p>2. Self-hosted version (GitHub):
<a href="https://github.com/robertjakob/rigorous">https://github.com/robertjakob/rigorous</a>
- Use your own OpenAI API keys
- Full control over the review process
- Customize agents and criteria
- MIT licensed<p>The system is particularly useful for researchers preparing manuscripts before submission to co-authors or target journals.<p>Would love to get feedback from the HN community, especially from PhDs and researchers across all academic fields. The project is open source and we welcome contributions!<p>GitHub: <a href="https://github.com/robertjakob/rigorous">https://github.com/robertjakob/rigorous</a>

Web dev is still fun if you want it to be
I wrote a silly toy website and went out of my way to enjoy it, rather than endure it.<p>I wrote up my thoughts. Maybe they'll resonate with you. Maybe they'll infuriate you. As long as they make you feel something more than a cosmic shrug I'll be pleased.
Show HN: I made a Zero-config tool to visualize your code
I built Staying – a tool that instantly turns your code into interactive animations with no setup required. Just write or paste your code and hit "Visualize". No installs, no accounts, no configuration.
*Supports*: Python, JavaScript & experimental C++
Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent
I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero!<p>In case you don't know what an FPGA is, this phrase summarizes it perfectly:
"FPGAs work like this. You don't tell them what to do, you tell them what to BE."
You don't program them, but you rewrite the circuits they contain!<p>So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs.<p>This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple weeks of work. (Thanks for the pcb reviews on r/PrintedCircuitBoard )<p>(All the sources on github under an open source license :D)<p>PS.

Show HN: Every problem and solution in Beyond Cracking the Coding Interview
Hey HN, I'm Aline, founder of interviewing.io and one of the authors of Beyond Cracking the Coding Interview (the official sequel to CTCI).<p>We just compiled every problem (and solution) in the book and made them available for free. There are ~230 problems in total. Some of them are classics like n-queens, but almost all are new and not found in the original CTCI.<p>You can read through the problems and solutions, or you work them with our AI Interviewer, which is also free. I'd recommend doing AI Interviewer before you read the solutions, but you can do it in whichever order you like. (When you first get into AI Interviewer, you can configure which topics you want problems on, and at what difficulty level, and you can add topics and change difficulty levels as you go.)<p>Here's the link: <a href="https://start.interviewing.io/beyond-ctci/all-problems/technical-topics" rel="nofollow">https://start.interviewing.io/beyond-ctci/all-problems/techn...</a> (You'll have to create an account if you don't already have one, but there's nothing else you need to do to access all the things.)
