Show HN: Resumecreator.io – I built a simple resume builder Hi HN! I'm a developer who noticed that I haven't done much experimentation lately. I decided I wanted to change that this year. This month I built a simple resume builder with the main goal of practicing front-end development, and to scratch an itch I had when updating my resume. :) After it was functional enough, I casually shared with some friends to express my enjoyment of crafting something just for the sake of having some fun. To my surprise they ended up asking how they could send to others. So I went one step further, due to my pure excitement, and hosted it on Netlify to make publicly available. In case you're curious, I used the React component library Mantine[1] in this project. I loved it, so I definitely recommend to check it out for your next React project. Have thoughts to share? I would love to know! :) If you're postponing starting that project you have been thinking of, just do it. Right now.

Show HN: Bugfruit – a simple embedded key-value store Hey HN! I work on a database for my day-job and I realized I had never written one from scratch, so I wrote bugfruit! Once I was mostly satisfied with it, I looked up some benchmarks to compare my simple database to other brand name key-value stores. I was surprised to see that mine held up fairly well on the subset of benchmarks I replicated. So I used the Pavlo Database Naming System [0] to name it and open-sourced the code. I'd love to hear any feedback you might have on it! [0] https://ift.tt/SP39GCw... https://ift.tt/KWIMJbT May 30, 2022 at 04:14AM

Show HN: NetBird – A P2P Network with WebRTC, WireGuard, SSO, and Zero Trust Hey folks! We have just released NetBird. It is a big update so I decided to share it here and get your feedback :) NetBird creates an overlay peer-to-peer network connecting machines automatically regardless of their location (home, office, data center, container, cloud, or edge environments) unifying virtual private network management experience. It uses ICE protocol (WebRTC) to negotiate p2p connections and WireGuard (kernel module, when possible) to create a fast and encrypted tunnel between machines, falling back to relay (TURN) in case a p2p connection isn't possible. Pretty much just a client application installation is needed, the rest is done by the software! Sharing the project with you wasn't the only purpose of the post. I wanted to discuss the future and vision behind it. I'm pretty sure that in a few years, such seamless connectivity without the hassle of configuring firewalls, managi

Show HN: WebRTC Nuts and Bolts, A holistic way of understanding how WebRTC runs Hi HN! I’m so excited to show my first open-source project and first post here. I initially started this project to learn Go language, it is an experimental project. The main goal is to track the adventure of a WebRTC stream from start to finish, by debugging the project or tracking the output at console. By trying out this project, you will deep dive into the steps which are taken while starting up a WebRTC session, and more. It consists of a web UI (TypeScript) and a server back-end (Golang) projects. They can run on Docker containers, in development mode or production mode, you can find details in the README file. After some progress on the development, I decided to pivot my experimental work to a walkthrough document. Because although there are lots of resources that exist already on the Internet, they cover small chunks of WebRTC concepts or protocols atomically. And they use the standard way of induct

When the real world shut down, there was suddenly nothing to monitor on streets and in restaurants, so I set out to try and evolve our real time face recognition system into a video codec for high quality face-to-face online interactions, as I was not satisfied with the quality of Zoom and friends. I got it to work, and the first release for IOS was just approved on Apple's app store, link: https://ift.tt/jbEU0s5 The way it works is that you create a meeting URL, which you can share out-of-band, for instance via slack or text message.

Show HN: Muse 2.0 with local-first sync Hey HN, I want to share with you something I and my four colleagues have been working on for the last several years. It’s a whiteboarding and notes tool called Muse[1]. We just released a 2.0 version which includes local-first sync. A little backstory: I’m one of the authors of the 2019 essay Local-first software[2]. (Past HN discussions[3][4].) The thesis is to reclaim some of the ownership over our data that we’ve lost in the transition from filesystems to cloud/SaaS. So I’m excited to bring CRDT technology “out of the lab” and into a commercial product as a chance to prove the value of local-first in real-world usage. As a developer and computing enthusiast, I care about abstract ideas like data ownership. But for most users I think the benefits of local-first will surface in how it feels to use the software day-to-day. One example is ability to work offline or in unstable network conditions: any changes between devices will be automatically m

It currently supports Postgres, MySQL, and SQLite, as well as newer-generation databases like ClickHouse, PlanetScale, and Yugabyte (and more coming very soon!). Think of Arctype as “phpMyAdmin meets Postman”. Most of our team grew up learning how to program using the LAMP stack and we missed the experience of interacting with our databases using phpMyAdmin. We wanted to bring back the experience of a simple app that lets you explore and query your databases, but with an updated and modernized interface. At the same time, we were heavily inspired by the ease-of-use and collaboration features of Postman. We wanted to create a super useful, collaborative app like Postman t

Today Vantage is launching Autopilot: a managed service that identifies and applies savings to your AWS account by automating the buying and selling of reserved instances. This is saving early customers over 50% in some cases. Upon opting into Autopilot, if your on-demand EC2 costs increase, Vantage purchases 3 year, no-upfront reserved instances. In the event your compute spend decreases, Autopilot will list your reserved instances for sale in the AWS EC2 Reserved Instance marketplace on your behalf. Unlike other providers that charge you egregious fees (20% or more), Autopilot only charges you 5% of the savings found. These are your cost savings and I believe you should have as much of the benefit as possible. Some of our current customers include Barstool Sports, PlanetScale, Panther, and MIT.

I built an interactive demo for TypeIt’s website (https://ift.tt/WGdxwDo) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal knowledge of the algorithmic approaches to string diffing, and so things got frustrating real fast. But then I figured out a way to build it out using JavaScript symbols to link characters that helped ease the complexity a ton. It all resulted in “striff,” which comes in at just over 600 bytes gzipped, and that I’ve been using in production for a couple of months now. I

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.)

Show HN: A collaborative pixel drawing game for when you're bored (Attempt #2) Previous thread: https://ift.tt/OJmXEgt Hello again HN! It's been 3 months since I last submitted this project and the back-end server software melted down. I was really bummed that many people didn't get to play, so I've spent most of my spare time since that last post completely rewriting the back-end server software using small, carefully selected dependencies (C99, sqlite, mongoose.ws & cJSON) I've done some basic performance testing and I'm cautiously optimistic that it can now handle up to ~1000 concurrent users. If you have any ideas for improvements, do let me know! Bots are permitted, but try and do something creative instead of just filling the canvas with junk :^) You can view the source code for the new back-end here: https://ift.tt/LZIvSa4 You can also check out a recent time-lapse here: https://www.youtube.com/watch?v=FUmnUvTqn6M The time-lapse gets generated from th

Show HN: Character-Based Git Conflict Resolution Hello HN! I was always annoyed by conflicts that can be solved automatically, but still need human intervention. E.g. two people changing the same line, but at different, non-conflicting positions. So I searched for a character based patching library and found this nice article https://ift.tt/dULXRsn and its corresponding library https://ift.tt/sPGflei . Parsing git conflicts, applying patches and showing some useful diffs in the UI helps me to solve 80% of my conflicts automatically. I hope it can help you too. Happy Hacking! https://ift.tt/aQqYSiL May 13, 2022 at 11:31PM

Show HN: Watermelon – open-source VSC ext. to document code and view Git blame Hey there HN! We're a pair of devs looking to get feedback for our open-source project. We're remote engineers who have contracted for many clients overseas. There's a problem that all codebases share: Onboarding devs to a new codebase is hard no matter what. We're also open-source engineers and learned about the techniques used in OSS to tackle the problem. Please give us your feedback.

Scooter Sidewalk Riding Detection Technology Demonstration By Sarah Hellman The SFMTA held a public demonstration of e-scooter sidewalk riding detection technology on Thursday, May 12, 2022 involving the three permittees: Lime, Scoot, and Spin. The demonstrations were required as part of the SFMTA’s Powered Scooter Share Program, which ensures that shared scooter operations support the City’s recovery from the pandemic in a safe, sustainable, and equitable way. This includes keeping our sidewalks safe, particularly for our most vulnerable pedestrians and road users.   Scooter sidewalk riding is illegal pursuant to the California Vehicle Code Section §21235(g) and poses significant risk to pedestrian and scooter rider safety, particularly for older adults or persons with disabilities using the sidewalk. Sidewalk riding detection technology enables the device to detect sidewalk riding in real time. Once detected, the scooter automatically slows the rider to a safer speed. We believe

Show HN: Dockerfile Generator While it's not hard to write a Dockerfile, I think it's hard to write a good one. Every language has its own quirks, and every framework has a special way of building things. I was looking for a collection of well-written and well-maintained Dockerfiles, but I couldn't find one. Thus, I thought of creating one! I realized it's not enough to have a simple Dockerfile. Sometimes you need other files for your build: nginx.conf, php.ini, my.cnf, etc. I also realized that people have different preferences. In Node, some use NPM, some use YARN, some use PNPM. In PHP, some use Apache, some use FPM with Nginx. So I build a set of "builders", Dockerfile generators. You define a form using JSON Schema, and then define a function "generate" that returns an array of files. In the future, I can make a CLI tool that will generate prompts, similar to how the form is generated on the web. For now, I only implemented a builder for Next.js

Show HN: YouCode, a Search Engine for Coding Hi Hacker News, We're Bryan and Richard, cofounders of you.com. Together with our team of engineers, we are working on YouCode, a search engine for people who code. You can try it at code.you.com. The main idea is to make the search experience better and more efficient when coding. We’d love your feedback for a few use cases that we have in mind so far: * searching through StackOverflow for quick code snippets: reverting a git commit for example [1] * searching through GitHub Issues: when you’re getting an error message that looks unfamiliar [2, 3] * searching through the documentation for quick reference: PyTorch [4], HuggingFace [5], Docker, PyPi, AWS, MDN, and several others * searching for walkthroughs, tutorials, tips, and quick intros to a new subject: Medium [6], Tutorials Point, Geeks for Geeks, and others as well * searching for utilities: code completion (from a large language model that writes code) [7], JSON validator/formatt

Show HN: Catchy melodies made with a diffusion-based neural net assistant I've created a diffusion-based neural net generative assistant that makes creating new melodies much easier, even for non-musicians like me. These are meant to be just the catchy "hook" parts of songs, so more work is required to make them into full songs, but this is already handled well by existing products (e.g. there are plugins that can suggest a few possible chord progressions based on the melody and there is even good singing software that I used without any tweaks to make the “voice” playlist: Synthesizer V Studio). This side project turned out to be quite challenging because of how little data there is to train on - several orders of magnitude less than DALL-E or GPT-3 had available for its training, so it required a deep dive into research of new generalization and augmentation techniques and some feature engineering.
