Show HN: Fern, a language for defining REST APIs that compiles into OpenAPI https://ift.tt/cfxi2zg

Show HN: Fern, a language for defining REST APIs that compiles into OpenAPI Hi HN, this is Danny, Deep, and Zach. We built Fern after our previous ed tech startup failed. We were frustrated with how much time we spent writing “API code” instead of working on the actual product. We tried to use OpenAPI but we were underwhelmed - the generated code wasn’t idiomatic and it still required manual work (custom templates, scripts, manually publishing SDKs to registries). The Fern compiler takes your API as input and invokes generators that output things like: SDKs, server code, a Postman collection, and an OpenAPI spec. Some technical highlights about the compiler + generators: - The compiler (available as a CLI) handles syntactic + semantic validation. It also includes a linter that encodes best practices. If your API Definition compiles, you can have high confidence that the SDKs will generate correctly. - After all the parsing and validation, the compiler outputs an intermediate representation that gets handed off to the generators. This prevents each generator from re-implementing the same parsing and validation logic. - Each generator is implemented in the language it is targeting - e.g. the Python generators are written in Python, the TypeScript generators are written in TS. It makes the SDKs more idiomatic because every programming language generally has the best tooling/libraries for generating code in itself. We also think it’ll make community involvement + contribution easier. - The generators can output the code to disk, but also push the code to a Github repo and publish the SDK directly to registries (e.g. npm, Maven). We are looking for devs to use Fern for API development. If you have any feedback about the process, compiler, or the generated code, we’d love to hear it.

Show HN: Val Town – A Cloud Scripting Site https://ift.tt/CwXvGt0

Show HN: Val Town – A Cloud Scripting Site Hey HN! We're so excited to show you Val Town ( https://val.town )! A "val" is a JavaScript/TypeScript function or value that runs on our servers. We aim to get you from idea to running code in seconds: type code, run it, get its API endpoint, schedule it - all from the browser, in a couple keystrokes. We're a startup of 4 people, mostly in NYC. We've been working on this for 6 months and are eager for feedback from the HN community. Why do we need yet another online coding IDE? While researching devtools[1], I found myself wanting something halfway between Replit and Zapier: a tool that makes hosting, deploying, scheduling, and authenticating easy, but is first-and-foremost a programming tool. We added `console.email` to the runtime to make it incredibly easy to email yourself. We don't have npm imports yet, but we do have a low-friction system that treats every user as a namespace, so you can refer to `@me.foo + 1` or `@yourFriend.bar()` right in your code. There are a lot of thorny implications this newfangled import scheme creates, but also many joyous and carefree coding experiences! One of my favorite features is that we store every evaluation, up and down the callstack, including inputs, outputs, logs, etc, which has been an amazing aid to debugging. So far, Val Town is mostly used for what we're calling "programmatic notifications": query a data source for new items on an interval and email them to yourself. Get notified when users you "follow" post on Hacker News: https://ift.tt/p3Qtu75 Get notified when to close your window during fire season in SF: https://ift.tt/t7G46QN Get notified when there are new citations on a paper: https://ift.tt/W6vQRfc Subscribe to RSS feeds: https://ift.tt/ZBghrn9 A good place to get started would be forking one of those vals and modifying it to suit your needs. Some folks are using the tool in other ways, such as in webhook contexts, and we encourage those uses as well. We'd LOVE to pair-program with anyone looking to try out the tool and give feedback.

Show HN: We’re building a gaming console for the browser https://ift.tt/BNR30ix

Show HN: We’re building a gaming console for the browser hey all, We’re excited to share bash.gg - a way to play all games on your browser. Our mission is to enable you to play games, from any device, with your friends. We're planning on using a combination of WebGL (soon WebGPU) & pixel streaming to run any game. Our product is going viral within a few school districts, here’s what we’ve built. The Problem: Poor Experiences: Mobile gaming is limited by hardware. Most mobile games are spammy & focused on optimizing value extraction. Existing web games are junk. Expensive: For good games, you need a console or PC, costing $600 - $3k. Not Scalable: Consoles are sold at a loss & desktop computers are too expensive. Necessary hardware is increasing in size and cost. On the other hand, games continue to get more computationally expensive. bash.gg: Great Experiences: We’re bringing the best games from PC and console to your browser so you can play from any device instantly. Affordable: You don’t need expensive hardware, just a stable internet connection. Scalable: As games demand more resources, they’re run in the cloud. The games that don’t need all that power can run in a browser. TLDR: Consoles make it difficult to play with all of your friends. If your friend has Xbox, and you have Playstation - you might not be able to play together. Having games on the browser lets anyone play, by just clicking a link. Not only that, but you can chat and play, all in one place. In progress features: pixel streaming (quic + webcodecs), community features, live audio/text chat (should release within in 2 weeks) Excited to hear what you all think! https://bash.gg January 11, 2023 at 11:25PM

Show HN: Syncthing-map – a utility to map syncthing devices and folders https://ift.tt/d29K53i

Show HN: Syncthing-map – a utility to map syncthing devices and folders If you use the excellent Syncthing[1], you may quickly be lost in the various shares between devices. I was. This was the trigger to write a small application that creates a map of your devices, their folders, and how each is shared. It is directly based on the configuration file of each device. The stable version[2] generates a HTML file you can render in a browser to show the map (based on mermaid.js[3]). I just released an experimental feature[4] that starts a web server which will dynamically create the map based on configurations shared by the devices. Binaries are available as well[5]. I would be glad to hear any comments or advice (I am an amateur developper). Thanks! [1] https://syncthing.net/ [2] https://ift.tt/4mnIDsH [3] https://ift.tt/pBePqiY [4] https://ift.tt/w9xnSfR...

Show HN: Ecode – A minimalist and fast open-source code editor https://ift.tt/XbTC8oY

Show HN: Ecode – A minimalist and fast open-source code editor Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them). The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but it's a work in progress, and many features are still pending. Some minor hints on how to use it: Folders are used as project (and .gitignore is used to ignore files) The wheel icon on the top-right has all the options you need (Ctrl/Cmd + M to show). Some keybidings to navigate any project (navigation is keyboard driven): Ctrl/Cmd + K = Locate Files Ctrl/Cmd + Shift + F = Global Search Ctrl/Cmd + Number (Go to tab #) https://ift.tt/tugNRXS January 10, 2023 at 10:51AM

Show HN: PipeScore – FOSS Bagpipe Notation Software https://ift.tt/7mwBSNt

Show HN: PipeScore – FOSS Bagpipe Notation Software I've been working on some version of this since May 2019. It is a web app that allows writing out music for the Highland bagpipe. While it uses the same notation as normal music, bagpipe music tends to have a greater focus on gracenotes (embellishments). Most music software does not deal with this very well (e.g. MuseScore just displays a list of every single possible embellishment, of which there are hundreds [1]). PipeScore instead takes advantage of the fact that the form of many embellishments is dependent on the notes adjacent to it, allowing it to reduce the number of options down to just 13.

Show HN: FixScript, an embedded/standalone language with custom syntax additions Hello, I want to introduce you to a programming language that I've been working on for a few years and is ready to be shared with a broader community. Feel free to ask any question about it, it's hard to describe what it is all about in a single blog post. For examples of a more complex code I recommend looking into to the "src" directory in the SDK. And here are some documentation links: https://ift.tt/lnx6toi https://ift.tt/g5VsLMk https://ift.tt/iEe3jo0 January 10, 2023 at 01:26AM

Show HN: Tortoise TTS as an at-cost open-source pay-per-second API https://ift.tt/u61WX70

Show HN: Tortoise TTS as an at-cost open-source pay-per-second API Tortoise TTS is the best TTS available today. We built an open-source, at cost, pay per second API for it. The quality of intonation it generates is unparalleled, and we hope our at-cost API will make it easier for people to build on top! This allows folks to run via a single API call - it costs $0.03/query. The WAV file is downloadable, we apply no restrictions. We're open-sourcing all our work — we made Tortoise run 30% faster, and have more improvements coming. If you're keen to contribute we can help with ideas, pointers, compute and data; just DM us. Our fork with the improvements can be found at https://ift.tt/m95yDe2 . The deployment code can be found at https://ift.tt/eJ6oBQ0 . There are already great alternatives for using : i) @mdnest_r's awesome Huggingface Spaces, ii) original Google Colab, iii) host it yourself. Our work should accelerate those who need an API, don't want to spend time/$ hosting and need a scalable infra backing them. We're especially excited about combining text-to-speech with content generated from LLMs, and about how it fits into video creation tools. Tortoise in its current form is also inaccessible to non-technical users, which is why we are also providing a simple UI on top (also "at-cost"): https://tts.themetavoice.xyz To use, generate an API key on https://tts.themetavoice.xyz and call via POST request. Or use the web UI. Or run your own deployment. https://twitter.com/vatsal_aggarwal/status/1612536547248836608 January 10, 2023 at 01:35AM
