Show HN: Wavvy – web-based audio editor (Audacity port)
I originally developed a WASM port of wxWidgets for <a href="https://dj.app/" rel="nofollow">https://dj.app/</a>. When it came time to open source wxWidgets-wasm, I decided to port another complex app as a test case, and Audacity seemed like the obvious choice. In the process, I also needed to write a new host API for PortAudio for playback and recording in the browser.<p><a href="https://github.com/ahilss/wxWidgets-wasm" rel="nofollow">https://github.com/ahilss/wxWidgets-wasm</a><p><a href="https://github.com/ahilss/portaudio-wasm" rel="nofollow">https://github.com/ahilss/portaudio-wasm</a><p><a href="https://github.com/ahilss/wavvy" rel="nofollow">https://github.com/ahilss/wavvy</a>
Show HN: I'm building an open-source Amazon
A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc.<p>The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly.<p>This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing marketplace.<p>In 2019, I started building the first piece, Openship, an order management system that lets you source orders and fulfill them from anywhere. Now that that’s in stable release, next up is Openfront (an e-commerce platform for storefronts) and Opensupport (ticketing software for customer support). Together, they provide the staples for any modern business: sales, fulfillment, support.<p>Let me know what you guys think of the idea and if you see any potential pitfalls.

Show HN: AutoHotkey for Linux
Hello HN,<p>this is the first functional reimplementation of AutoHotkey [1] for Unix-like systems, as far as I am aware. Half the commands are still missing, but everything important is done, as I have worked a lot on it over the past two months. Converting scripts into stand alone binaries is also supported. Hope this will find some adoption eventually. :-) - This implementation focuses on v1.0-like classic syntax from 2004 (!). This is a significant <i>subset</i> of the popular current v1.1 syntax from Windows (AHK_L). The reason this does not (yet?) target the full Windows spec is how complex it is. Notably, there's also another ongoing project which targets v2 called KeySharp [2].<p>If you are not aware of what AHK is, it is an easy but capable scripting language for automation and Hotkeys, and all sorts of visual things like GUIs.<p>If you want to learn more, there plenty of info on the repo, the docs html, and there's an active AHK Discord too, and I am personally also checking the forums and HN of course.<p>[1] <a href="https://www.autohotkey.com/" rel="nofollow">https://www.autohotkey.com/</a>

Show HN: I built a tool to help you read Hacker News on Kindle
Hi HN, I'm Daniel Nguyen. In June, I quit my job to start indie hacking full-time.<p>The idea of KTool first came to my mind when I was reading "Ask HN: I'm a software engineer going blind, how should I prepare?"[0]<p>I've been wearing glasses since I was 5. My right eye is basically blind. Doctors said there is no chance to cure it.<p>I was genuinely scared. Like holy shit, if my left eye stops working, my life is done. Since then I've been very conscious about time spent on computer screens.<p>That's when I started using Kindle-related products: to offload as many reading materials as possible to the Kindle. I was a happy customer of Push to Kindle. Great product!<p>Then I ran into multiple limitations which led me to build KTool: a tool to send anything online to Kindle. Blog posts, Twitter threads, Hacker News discussions, RSS, newsletters... you name it.<p>But I'm not here to pitch my vision for KTool.<p>I built a specific tool to help you send HN discussions to your Kindle. And in the spirit of Show HN, it doesn't require an account. If you don't own a Kindle, there is the option to download the EPUB.<p>Let me know what you think. Any feedback will be much appreciated.<p>If you're a Kindle owner and you read a lot of online content, give KTool a try.<p>[0]: <a href="https://news.ycombinator.com/item?id=22918980" rel="nofollow">https://news.ycombinator.com/item?id=22918980</a>

Show HN: Devbox – Easy, predictable shells and containers
Devbox is a command-line tool that lets you easily create isolated shells and containers. You start by defining the list of packages required by your development environment, and devbox uses that definition to create an isolated environment just for your application.<p>In practice, Devbox works similar to a package manager like yarn – except the packages it manages are at the operating-system level (the sort of thing you would normally install with brew or apt-get).<p>See it in action: <a href="https://youtu.be/WMBaXQZmDoA" rel="nofollow">https://youtu.be/WMBaXQZmDoA</a>

Show HN: Browse HN Together in Three.js
Hey HN,<p>We’re Philip, Amby, and Declan, and we made “multiplayer virtual computers” that you can embed anywhere, including 3D spaces. We decided to build this because we noticed that embedding third-party apps and websites can be a nightmare due to incompatible platforms, security issues, and poor UX. Adding multiplayer functionality to these embeds makes this problem exponentially more difficult.<p>On the backend, we’re spinning up a VM and running a resource-optimized fork of Chromium which we then stream to participants via WebRTC. Since we’re hosting the servers running the applications, multiple users can connect and control the virtual computer seamlessly, and their client just needs to handle a video stream.<p>If you want to add multiplayer virtual computers to your own app, you can sign up on <a href="https://hyperbeam.com/?ch=hn&cm=hn1" rel="nofollow">https://hyperbeam.com/?ch=hn&cm=hn1</a>, grab a free API key, and throw the provided embed URL in an iframe in your app.<p>You can also play around more with the Three.js demo in our interactive sandbox: <a href="https://app.sideguide.dev/hyperbeam/threejs/" rel="nofollow">https://app.sideguide.dev/hyperbeam/threejs/</a><p>If you have any questions or feedback, feel free to comment or shoot me an email at declan@hyperbeam.com.<p>Thanks!<p>Docs: <a href="https://docs.hyperbeam.com" rel="nofollow">https://docs.hyperbeam.com</a>
