Show HN: Open-source tool to deploy infrastructure in any cloud https://ift.tt/6Cal8nX

Show HN: Open-source tool to deploy infrastructure in any cloud We have been working on multy.dev, an open-source cloud agnostic API that makes it easy to deploy the same infrastructure to any cloud provider using native managed services. The motivation was the realisation that, even when using Terraform, migrating infrastructure code requires an end-to-end re-write. Even though most core resources are the same in any major cloud, developers need to learn a new provider to deploy the same infrastructure when moving providers. We are still in early days of development and currently support the core services from AWS and Azure: - Networking (virtual_network, subnet, route_table, security_group, network_interface, public_ip) - Compute (virtual_machine, managed kubernetes) - Database (managed MySQL databases) - Vault (managed secrets) - Storage (managed storage) - Abstraction of cloud differences (Azure VM public vs AWS EC2 private by default) - Deployment through Terraform We’re looking for feedback from other developers about our approach. Let us know your thoughts! GitHub: https://ift.tt/xIdgWSj https://multy.dev May 16, 2022 at 11:05PM

Show HN: KittenDNS – easy to setup, rule engine, LetsEncrypt compatible https://ift.tt/JEbrc0i

Show HN: KittenDNS – easy to setup, rule engine, LetsEncrypt compatible My goal was to create a DNS server as simple as the LDAP server I've been contributing to (glauth) and here it is: https://ift.tt/i6S4IHQ A few things to know about it: - It is easy to configure using a Toml file - I am using it to bail my coredns/etcd instances when under attack - (yes, it also works as a service location server) - It comes with a simple, plain English, rule engine that doesn't do much at this point - It can be used with LetsEncrypt. I use it to retrieve certificates for my home servers. - RFC: all the nice ones :) Anyway, feedback is welcome. May 16, 2022 at 03:04AM

Show HN: Babeloop, a new music sight-reading webapp https://ift.tt/DGSYZ9E

Show HN: Babeloop, a new music sight-reading webapp Backstory: I have a kid learning to play the clarinet in a music conservatory, which involves compulsory sight reading classes. Teaching for sight reading is done on books. The idea for this app is to port the method online, so that it's easier to practice and follow one's progress. It should also be more fun, and, for those so inclined, competitive. The learning method is based on landmarks: for each clef one first learns the position of 2-3 landmarks, and then each note is in relation to a landmark. So for example, if you know where the middle G is on the treble clef, then you can learn fast that 2 positions up (next line) is B, and two positions down is E. (Anecdotally, in an earlier iteration of the app, landmark notes were displayed using specific colors; but users learned colors instead of the note position on the staff, and when they moved to a level without colors (or an actual score) they were completely lost.) The app doesn't try to teach keyboard playing, or fingering for any other instrument for that matter. It only helps associate the position of a note on the staff with a name, in a given clef. It doesn't deal with octaves: a C3 is a C4 is a C; or accidentals: a sharp G is a flat G is a G. It also doesn't wait for user input, as other apps do. Music doesn't work that way; but more importantly, the point is to learn to recognize intervals instantly, not count them. No account is necessary to use the app, only to participate in the leaderboard, and save one's score in case of device reset (or to use more than one device). When an account is created, the data is stored on the server in SQLite; I'm curious to see how far it can go. (Without an account, no data leaves the device.) It's still a little rough around the edges but should work ok in reasonably recent browsers. On the client side, it uses VexFlow to display notes, staff and clefs, but animations are done using CSS transitions (not JS), to be mobile friendly. Tone.js helps provide a more accurate timing than a simple setInterval. Icons are coded in SVG by hand; for simple shapes, this is surprisingly fun and straightforward to do. https://ift.tt/jXSIi5Q May 15, 2022 at 10:25PM
