Show HN: My iOS app to practice sight reading (10 years in the App Store)
Hello HN, this has been my personal project for quite some time now. It has been a slowly evolving project over the years and its core function is for users to expose themselves to progressively more difficult lessons of music notes.<p>NOTE: It is free and there are no ads. There is an in app purchase but most of the app doesn't require it.

Show HN: LinkedIn sucks, so I built a better one
LinkedIn feels more like Facebook every day — noisy feeds, fake engagement, and everyone shouting into the void.<p>Thats why I used to built a personal microsite on Squarespace and uploaded a video resume to YouTube to stand out - it helped me land interviews and get into Big Tech.<p>But I always wondered: why isn’t there a platform designed to help you stand out like that?<p>So I built OpenSpot: a public, curated platform where you can showcase who you are — with video, audio, and proof of your work. No endless feeds. No humblebrags. Just real people open to new opportunities.<p>We’ve already onboarded a few companies, so recruiters can reach out to you directly. But you can also connect with other standout folks and supercharge your network.<p>Just upload your resume and we´ll automatically generate your profile in under 1 minute.<p>It’s early, but feels like something people actually need.
Would love your thoughts.

Show HN: I built website for sharing Drum Patterns
Originally started as a project to restore patterns from now defunct website 808.pixll.de just for myself, but eventually i decided to share it with others. I've seen this website mentioned a couple of times on HN:)<p>Currently it only supports Roland TR-808, but there will be more.

Show HN: Hyperbrowser MCP Server – Connect AI agents to the web through browsers
Hi HN! Excited to share our MCP Server at Hyperbrowser - something we’ve been working on for a few days. We think it’s a pretty neat way to connect LLMs and IDEs like Cursor / Windsurf to the internet.<p>Our MCP server exposes seven tools for data collection and browsing:<p>1. `scrape_webpage` - Extract formatted (markdown, screenshot etc) content from any webpage<p>2. `crawl_webpages` - Navigate through multiple linked pages and extract LLM-friendly formatted content<p>3. `extract_structured_data` - Convert messy HTML into structured JSON<p>4. `search_with_bing` - Query the web and get results with Bing search<p>5. `browser_use_agent` - Fast, lightweight browser automation with the Browser Use agent<p>6. `openai_computer_use_agent` - General-purpose automation using OpenAI’s CUA model<p>7. `claude_computer_use_agent` - Complex browser tasks using Claude computer use<p>You can connect the server to Cursor, Windsurf, Claude desktop, and any other MCP clients with this command `npx -y hyperbrowser-mcp` and a Hyperbrowser API key. We're running this on our cloud browser infrastructure that we've been developing for the past few months – it handles captchas, proxies, and stealth browsing automatically.<p>Some fun things you can do with it: (1) deep research with claude desktop, (2) summarizing the latest HN posts, (3) creating full applications from short gists in Cursor, (3) automating code review in cursor, (4) generating llms.txt for any website with windsurf, (5) ordering sushi from windsurf (admittedly, this is just for fun - probably not actually going to do this myself).<p>We're building this server in the open and would love feedback from anyone building agents or working with web automation. If you find bugs or have feature requests, please let us know! One big issue with MCPs in general is that the installation UX sucks and auth credentials have to be hardcoded. We don’t have a solution to this right now but Anthropic seems to be working on something here so excited for that to come out. Love to hear any other complaints / thoughts you have about the server itself, Hyperbrowser, or the installation experience.<p>You can check us out at <a href="https://hyperbrowser.ai">https://hyperbrowser.ai</a> or check out the source code at <a href="https://github.com/hyperbrowserai/mcp" rel="nofollow">https://github.com/hyperbrowserai/mcp</a>

Show HN: My Attempt to Organize the World of AI Dev Tools
I've been exploring the (not so=) amazing potential of AI in coding and have compiled a list of tools. From AI-powered IDEs to code generators, this resource is my contribution to the community.<p>I'm still on the fence about including txt2sql projects, as their functionality seems too basic to me.<p>And I'm personally maintaining this, so your feedback is wellcome.
Show HN: Torch Lens Maker – Differentiable Geometric Optics in PyTorch
Hello HN! For the past 6 months I've been working on an open source python library that implements differentiable geometric optics in PyTorch. It's very experimental still, but eventually the goal is to use it to design optical systems with a state of the art optimization framework and a beautiful code based API. Think OpenSCAD, but for optical systems.<p>Not only is PyTorch's autograd an amazing general purpose optimizer, but torch.nn (the neural network building blocks) can be used pretty much out of the box to model an optical system. This is because there is a strong analogy to be made between layers of a neural network, and optical elements in a so-called sequential optical system. So the magic is that we can stack lenses as if we were stacking Conv2D and ReLu layers and everything works out. Instead of Conv2D you have ray-surface collision detection, instead of ReLu you have the law of refraction. Designing lenses is surprisingly like training a neural network.<p>Check out the docs for examples of using the API. My favorite one is the rainbow :) <a href="https://victorpoughon.github.io/torchlensmaker/examples/rainbow" rel="nofollow">https://victorpoughon.github.io/torchlensmaker/examples/rain...</a><p>You should be able to `pip install torchlensmaker` to try it out, but I just set it up so let me know if there's any trouble.<p>I was part of the Winter 1'24 batch at the Recurse Center (<a href="https://www.recurse.com/" rel="nofollow">https://www.recurse.com/</a>) working on this project pretty much full time. I'm happy to talk about that experience too!
