Show HN: Goru, an experimental, Go-inspired concurrency library for Ruby https://ift.tt/r2jLgPS

Show HN: Goru, an experimental, Go-inspired concurrency library for Ruby Hey folks, wanted to show this off and get feedback. Still early/experimental but there are quite a few concepts I'm excited about here. This project came about while writing a program in Go and loving its approach to concurrency. Being a long-time Rubyist I immediately started to think about what similar concepts might look like in Ruby. I set out with two main design constraints: 1. Lightweight: I didn't want routines to be backed by fibers or threads. Having been involved some in the async project ( https://ift.tt/lVvM1N3 ), I had some experience using fibers for concurrency but was curious if they could be avoided. 2. Explicitness: Routine behavior must be written to describe exactly how it is to behave. I always felt like concurrent code was hard to fully understand because of the indirection involved. On the spectrum between tedium and magical I wanted to err more on the side of tedium with Goru. Goru routines are just blocks that are called once for every tick of the reactor. It is up to the developer to implement behavior in terms of a state machine, where on each tick the routine takes some action and then updates the state of the routine for the next tick. This fulfills both design constraints: 1. Because routines are just blocks, they weigh in at about ~345 bytes of memory overhead. 2. Routine behavior is explicit because it is written as a state machine inside the block. Couple more features worth noting: * Goru includes channels for buffered reading/writing (similar to channels in Go). * Goru ships with primitives for non-blocking IO to easily build things like http servers. Curious your thoughts! https://ift.tt/peUMHr2 April 3, 2023 at 07:17PM

Show HN: Shhhbb, an SSH BBS Hello all :) I made this BBS for fun and thought you all would enjoy it. It's not perfect, but it's been a fun exercise! see it: https://ift.tt/zy5w62N try it: ssh -p 2223 shhhbb.com host it: https://ift.tt/hjBrQxb why? Every year I challenge myself in some new way, this year it is to push one project per week. You might recognize my static site generator [0] or my releaser for go [1] from previous posts as one of these weekly projects. If you want to join me in doing this, it's been a blast and I highly recommend it! Maybe we can chat on the bbs about it :) [0] - bearclaw tiny static generator - https://ift.tt/iDdL1cF [1] - release.sh release builder for go - https://ift.tt/iDdL1cF need: I'd love a few co-conspirators, or even some new friends for the bbs software or the bbs itself. A lofty nice-to-have goal is meeting a few other similarly motivated people to conspire with on a weekly basis. If that's you, drop me a line! goals: I have about half of an admin interface endpoint pushed up, which I'd like to finish. I realized mid-commit that I'd lacked some other material in a previous commit, and in pushing it up, I ended up pushing half the admin feature. Stay tuned for that. I'd also like to implement a feature where I surrender the socket to a new process so I can upgrade the binary without dropping all of the connected users. I'm not sure on the feasibility of this, but all the words fit together, so it'll be tried. https://donuts-are-good.github.io/shhhbb/` April 2, 2023 at 10:10PM

Show HN: Integrating puzzle rush and spaced repetitions for chess training https://ift.tt/tPgXLsG

Show HN: Integrating puzzle rush and spaced repetitions for chess training Hi HN! I’m publicly releasing BraiMax Chess, a web app I built during the last three months; it’s based on a training technique which brought me from around 1700/1800 to 2000 rating (superblitz) on lichess. Here it is: https://ift.tt/oKT0ye6 Background story: during lockdown I decided to try and improve at chess, which I was playing online a lot. Bought a few books, tried all the websites and apps I found. This serious study helped a lot in understanding the game better, but didn’t improve my results as much as I hoped. It also was very hard work, and after a few months I stopped having the motivation to continue. Around that time I discovered Puzzle Rush on chess.com; that one was the most enjoyable chess-related thing I could do besides playing games, and it helped with tactics, but I soon plateaued - until I thought about combining that with spaced repetitions. I would manually review the puzzles I had failed, and add them to a rudimentary spaced repetitions system I had hacked together. It was a bit of work, but still enjoyable enough to stick to it; that’s when I started getting noticeably better and better, making fewer blunders, and climbing the rating. Late last year I decided to take some time off after leaving my last job; during the break I felt an itch and decided to create a website which would allow anybody to use the same technique I described above, but in a much easier/integrated way. After three months of full time work on it, it’s ready! Let me know what you think Dan https://ift.tt/YatgjO6 April 2, 2023 at 03:06PM

Show HN: Build your own no-code editor with Reka.js https://ift.tt/Ne2R7Sv

Show HN: Build your own no-code editor with Reka.js Much of the complexity surrounding building no-code editors come from architecting the state management system to power such editors: how can we allow end-users to create and edit entire UI components directly from the browser? Reka solves this by providing an AST-powered state system that enables end-users to create UI components that are nearly as complex as ones that developers could write in code; along with an interpreter to efficiently compute an output that could be rendered on the browser. Furthermore, Reka provides additional extensions, such as enabling real-time collaboration via CRDTs; or you could build a custom extension to support additional functionalities such as a commenting system. All that's left is for you to build your own UI abstractions on top of Reka — designing your editor UI/UX and providing easy-to-use buttons/controls for your end-users to mutate the underlying state in Reka.

Show HN: AI Shakespeare https://ift.tt/hEtVliJ

Show HN: AI Shakespeare These days thinking of ways to uniquely show off a text to speech model is tough, as there are a lot of them out there. We thought it would be fun for April 1 to show something a bit on the silly end of things -- we trained our TTS model on "Shakespearean" theatrical voices, and used GPT to generate short plays which are then "acted" out. This lets us show the versatility of our model, that we use in more "serious" settings for generating branded voices for particular languages or accents. It should be noted, the dataset is of our own curation; all voice actors were compensated with full knowledge of being used for TTS and were thrilled to be part of a creative project like this. We resample the speaker embedding space to find voices that are different from any one particular actor. https://ift.tt/CL9KGHx April 1, 2023 at 02:00PM

Show HN: Coursemate, connect with other self learners https://ift.tt/2VU6LDo

Show HN: Coursemate, connect with other self learners Hey Hacker News! My name is Collin, 18 years old and doing a gap year after finishing high school last year. This was my first real project after starting to learn web development around 5 months ago. I came up with this idea as it was a real pain for me to find other people from my country and especially my age, learning and taking online courses about the same stuff online. Lots of these online courses include their own discord communities and forums, but I still found it very hard to connect with other people in there. Thats why I built Coursemate. I would love to get your feedback on it! :) https://ift.tt/FedoA9J April 1, 2023 at 02:08PM

Show HN: Simply explain 20k concepts using GPT https://ift.tt/avzweuy

Show HN: Simply explain 20k concepts using GPT Hi HN! I made a tool that autogenerates simple, high-level explanations of concepts and organizes them in a somewhat university course-like structure so that it's easier to see how things are structured. Currently it has about 20,000 concepts on a range of topics but that's just what I generated so far, it should work with more obscure topics in the future. I love learning about random topics where I don't have a good background in like history or linguistics, but it's hard to figure out what topics there (you don't know what you don't know) are in certain fields and what they are even about, so this was a way to get the high level idea about random things that I wanted to know about. It also only uses the information in the GPT model at the moment, so obviously information can't be trusted completely and you should definitely double check any information you read here by Googling. I'm thinking of doing the Bing Chat approach for the next version and adding references, but don't have that yet Hopefully someone else finds this useful even if it's not perfect! https://ift.tt/ItKXifT April 1, 2023 at 03:54AM

Show HN: Cadseer. a parametric solid modeling CAD desktop application https://ift.tt/mFuzh0i

Show HN: Cadseer. a parametric solid modeling CAD desktop application Cadseer is in the same genre as: solidworks, inventor, freecad etc... Cadseer is alpha software, so lots of missing features, bugs, crashes, file incompatibilities etc... About me: I spent 15 years designing stamping dies on a high end cad system. During that time, I also developed and marketed extensions/plugins toward that cad system. Through that experience, I came disillusioned with 'vendor lock-in' and proprietary software in general. I basically retired, took the vow of poverty and moved all my computing to open source. I have since, and continue to, try and improve the open source cad environment. https://ift.tt/rUJVyEc April 1, 2023 at 12:05AM

Show HN: Multi-Display Screen Sharing with CoScreen by Datadog https://ift.tt/R79S8AO

Show HN: Multi-Display Screen Sharing with CoScreen by Datadog Good to be back on HN with all-new CoScreen, a little more than 3 years after it launched over here! With CoScreen 5.0, you can now share your windows from multiple displays at the same time, a long standing request by our most avid users and impossible in other apps. It also has a lightning-fast, Rust-based window compositing, scaling, and streaming engine now. CoScreen was always meant to be different so that you and your team can share your screens simultaneously and multi-directionally, and to be able to control what is being shared. We saw it as a natural extension and closely coupled with your OS — instant, fast, and seamless. A better way to pair program, debug tough incidents, or jam on great ideas by sharing multi-modal information like code, commands, graphs, or logs. All that made a lot of sense conceptually but to be frank, it was hard to get it right. Now a part of Datadog and with major parts of our app rewritten in Rust, we feel we’re closer than ever. Here’s what pair programmers liked about CoScreen, so we made it even better: - High definition code sharing: Windows are video-streamed in real-time at their native resolution whenever possible. You never have to search for your IDE anymore or be anxious to share the wrong window. - Multi-directional collaboration: You can share, while Alice shares, while Bob shares. Side-by-side, across multiple displays. With built-in crisp audio and video chat. - 60FPS+ super smooth mouse pointers. Type, click, and draw on any shared window as if it was your own. What some of you did NOT like, so we fixed it in CoScreen V5: - CPU utilization and latency have been reduced drastically as various parts of our desktop client are now implemented in Rust, building on crates such as cxx, rust-skia, iced, as well as Neon for our native remote control plugins. - No more accidental clicking into remote windows through the new remote window toggles. - You’re no longer bound by your displays, can share windows from multiple of them at the same time and even move them across displays while sharing without stopping. - You’ll also soon be able to join meetings from your browser from any platform. CoScreen runs on macOS (x64 and Apple Silicon), Windows, soon also on the web and is currently free. We’re planning to charge for larger teams and enterprise features in the future. Hopefully - finally - we’ll also have a Linux version one day. Tell us if you need it urgently and if you have any other requirements! https://ift.tt/BOv6pPr March 31, 2023 at 07:21PM
