Show HN: My programming language, building in public for 1 year https://ift.tt/GXc1N0H

Show HN: My programming language, building in public for 1 year My weekly(ish) video logs tracking my progress of building a completely sound statically typed language and structural editor. The motivation is to make lots of invalid programs unrepresentable. https://ift.tt/0qCaKZA January 1, 2023 at 05:42AM

Show HN: I made a simple, open source, chromatic tuner mobile app https://ift.tt/mNir9tG

Show HN: I made a simple, open source, chromatic tuner mobile app I'm a musician by night, software developer by day, and one of the minor frustrations I've always had was trying to find a simple tuner app for my phone. Looking at both the iOS and Android app stores, you'll find a lot of the top tuner apps are rather bloated with ads or subscription callouts. I thought I'd create a dead-simple minimalistic mobile chromatic tuner the way I would like it - open the app and tune my guitar. My work is in web with NodeJS and React, so I chose React Native since it was the easiest to understand coming from React. Flutter was also an option since the company I work for has a team working in that, but I thought it would be a bit too much effort to learn Dart. I learned a bit more about React rendering with this project as well. The main issue I had was trying to have a React state variable be constantly updated with any frequencies detected from the mic input, but that ended up

Show HN: I built a possible alternative to social media RSS https://ift.tt/hGzEDr3

Show HN: I built a possible alternative to social media RSS Hi there, I built a chrome extension to grab new posts from social media. Instagram, twitter, Pinterest, etc don't really allow for RSS so I worked on this alternative to get new posts. Hope this might be useful for some of you. https://ift.tt/FuaAHvX December 30, 2022 at 11:15PM

Show HN: Distilhn.com – Front-Page Articles Summarized with Machine Learning Hey HN, I've built a little website to show news articles with a summary so that I don't have to RTFA if I just want a rough sense of what it covers :) I also share the summaries in an RSS feed for those who'd prefer to use their own reader. Let me know what you think! https://ift.tt/rXx9FvU December 30, 2022 at 06:58PM

Show HN: Simple weather for your zip code https://ift.tt/snCLf2J

Show HN: Simple weather for your zip code Weather applications are bloated. This is the simplest implementation I could make using data from the weather.gov API. This simple weather application will retrieve the current 7-day weather for any of more than 33,000 US zip codes. To customize weather for your zip code, change the URL. The current URL is set to the zip code 90210. If you want both news and weather, that is available here: https://ift.tt/ut3QDmo https://ift.tt/9c2vdpA December 30, 2022 at 10:06AM

Show HN: Zcached, in-memory key-value cache wire-compatible with memcached https://ift.tt/UBEksjn

Show HN: Zcached, in-memory key-value cache wire-compatible with memcached zcached is an in-memory key-value cache exposing a memcached ASCII protocol-compatible interface, built on pluggable cache engines like Ristretto and freecache [0]. It's not performance-competitive with memcached, especially at higher thread counts. That said, it achieves about 1.1M ops/s, but at significantly higher P99 and P999 latency (as measured by memtier). See [1] and [2] for benchmark results from my 7950x-based workstation. Disclaimer: This is a hobby project created for fun while hacking over the holidays. zcached is not a commercial product and never will be. Don't use it in production; consider this a technology demo more than anything. I don't expect the source code to build outside of my environment, but for those interested in playing with it, binary artifacts are available at [3]. Try `zcached --address tcp:localhost:11211`.

Show HN: Merry Sky, Dark Sky replacement and merry-timeline open source lib https://ift.tt/5ACelhb

Show HN: Merry Sky, Dark Sky replacement and merry-timeline open source lib Hello HN, This is a website I worked on during the holidays to fill the void of the upcoming dark sky shutdown. For me, the precipitation timeline was a view I was heavily relying on for everyday activities and planning. I had not found any replacement from the various weather apps. When I found pirateweather.net as a backend API, it gave me the motivation to put the pieces together and get back the experience I enjoyed. I then added more functionalities that I think was missing from the website such as a weekly chart view. I've been using the website reliably over christmas holidays. Hope you enjoy it too! Also I open sourced the visual component for drawing the precipitation timeline and you can use it for drawing weather information or any other hourly activities really https://ift.tt/vfpP6ow Interested in your feedback! https://ift.tt/Ej2b7yl December 28, 2022 at 05:14AM

Show HN: Eleven – open-source alternative to Codespaces https://ift.tt/x3dmcB4

Show HN: Eleven – open-source alternative to Codespaces Hey HN, Eleven is the second project that I've built to learn Go. It lets you create a code sandbox in your cloud provider account easily. What's a "code sandbox"? Just a VM, running in your cloud provider account, with some runtimes pre-installed, your repositories cloned, a way to connect to it with your preferred editor (or via SSH) and a way to serve your apps easily via HTTP (with automatic HTTPS). You could use it to deploy your app, as a remote development environment or even to test some code. It's up to you. For example, to deploy a Node.JS app: $ eleven aws init hello-world --runtimes node@18.7.0 --repositories eleven-sh/hello-world > Success! The sandbox "hello-world" was initialized. $ ssh eleven/hello-world forever node index.js > Forever: command started. Run "forever stop" in current path to stop. $ eleven aws serve hello-world 8000 --as hello.eleven.sh > Success! T

Show HN: Secure end-to-end client sessions and API calls using crypto key pairs Hello. I made this project as an experiment in using key cryptography for user identity in a client <-> server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-) https://ift.tt/EiSmafo December 26, 2022 at 04:07AM
