Show HN: Go, JSON, Streaming and Generics I needed an easy way of handling large JSON blobs (200MB+) which I found is easy, but very verbose, using encoding/json. Dealing with deeply nested structs was a real pain so I wrote myself a wrapper around it - https://ift.tt/8nrLND2 - thanks to generics it can be very thin. https://ift.tt/8nrLND2 August 30, 2022 at 11:36PM
Show HN: I used DallE to create default avatars on my Creator community website I'm an indie dev and I built a community for creators to get together and collaborate with each other. Mostly for amateur creators, but some famous ones use it as well. It has about 700k users so far. There are about 100k of those users who don't bother to upload an avatar, so they've had a boring default avatar for nearly 7 years. Today, I used my credits on DallE to do make them a bit more fun. Since the creators self-identify, I was able to create specific kinds of avatars for them. For example, if a creator is a writer, my DallE prompt would be: "an oil painting portrait of a serious-looking owl, standing in front of a typewriter" Voice Actor: "oil painting portrait of a robot who is made out of a microphone, wearing a hat and headphones" Comic Illustrator. This one was a little more tough, so I chose 'tablet' as my key object: "Oil painting portrait of a brooding chameleon, wearing headphones and a hoodie, standing in front of tablet" Producer: "Oil painting portrait of a happy hedgehog with headphones on, wearing sunglasses, standing in front of a megaphone" All four images on this thread: https://twitter.com/_buf/status/1564327370219261954 Overall, I generated over 200+ new avatars. What a fantastic bit of tech! August 30, 2022 at 12:32AM
Show HN: SaaS for analyzing Bitcoin price movements Hello everyone! Our software offers a SaaS for analyzing Bitcoin price movements. We built an MVP model which recognizes levels in which BTC is at the top or bottom of the cycle. It is primarily intended for investors who are not financially sophisticated as a possible help to protect their investment. A short story about the creation of the product: A few of us, friends and ourselves, have always been maddened by the regular loss of the largest part of unrealized profit during bear markets which tend to be very hard on retail investors.On the other hand, a lot of friends blindly invested into bitcoin at ridiculous price levels based on hypes, bad instagram and YouTube influencers and mouth of word. We think that a large part of BTC and crypto investors live in a similar situation. With this goal, we teamed up with experts in the field of data science and finance, and created an algorithm that gives the BTC price score based on crucial market parameters. This score shows excellent results in real time and on backtesting. Our ultimate goal is to create a platform with various features, which will help retail investors to better navigate through the market, and to protect them from large losses. Therefore, we assumed that our USP has its audience among people who invest in BTC, and who had similar experiences in the bear market as we did. With the help of a landing page and paid Ads we want to test if a product market fit is possible with such a service. Unfortunately this turned out harder than we though. The problem lies in the fact the most popular social networks, among them Twitter as well, have problems with crypto advertisements. Although by definition we do not provide any financial product or services, not even financial advice, it may be that our service is interpreted that way and that we belong to a group where the space for marketing on social platforms is limited, rightly or wrongly. And we don’t know if we can change or adjust it at all, which drastically slows down our strategy of defining the product market fit. With that, we ask for feedback or advises to the following questions: -What do you think of our product? And do you think it is an idea that could be useful for BTC investors? If you don’t think so, how would you change/improve the product? -Is our product, like it is now, considered as financial advice? And is there anyway we can differentiate this kind of product from such a label? -How would you implement the product market fit strategy of our product in the fastest and most favorable way, if you could not publish advertisements on social networks? We are very grateful for any constructive advice or idea! You can find out more on our landing page (link above). Thank you!

Show HN: Hangman meets Wordle webapp in Angular Hey HN, I am a novice web developer, and I built a new webapp game in Angular that combines the game play of Hangman and Wordle. I chose this project because I wanted to learn Angular, while also developing something useful. I have some prior backend experience. And, I was pleasantly surprised with how much you can achieve in the pure JS/Typescript these days. For my app, the backend only sends the daily puzzle data in JSON, while the entire game logic and interactions are completely implemented in the frontend. I wrote around 4000 lines of the frontend code for this project. For me, the best part was RxJS integration in Angular. It also had a fair amount of learning curve. However, once you have learned the basics, it saves a lot of redundant boilerplate code and makes the code more readable and clean. You can play the game for free and there is no sign-up required: https://10letters.app The game does not save any user data at the server. All data is saved in the local storage. So, you can play the game again in the incognito mode, or after clearing your browser cache. If you have any questions or feedback, please feel free to add them in the comments. Thanks! https://10letters.app August 28, 2022 at 01:07AM
Show HN: Make Any CLI into a GUI in Acme Hey HN. I've become enamored with the Acme editor. It's fascinating because it turns the Vim paradigm on its head: instead of maximizing your use of the keyboard, maximize your use of the mouse. I think this helps optimize for information management, as opposed to text manipulation. I realized a lot of the CLIs I use have the same structure, and with a small program I could convert them into GUIs inside Acme and make them much easier to use. Let me know what you think. https://ift.tt/Pz7c2L3 August 28, 2022 at 12:45AM
Show HN: Browse HN Together in Three.js Hey HN, We’re Philip, Amby, and Declan, and we made “multiplayer virtual computers” that you can embed anywhere, including 3D spaces. We decided to build this because we noticed that embedding third-party apps and websites can be a nightmare due to incompatible platforms, security issues, and poor UX. Adding multiplayer functionality to these embeds makes this problem exponentially more difficult. On the backend, we’re spinning up a VM and running a resource-optimized fork of Chromium which we then stream to participants via WebRTC. Since we’re hosting the servers running the applications, multiple users can connect and control the virtual computer seamlessly, and their client just needs to handle a video stream. If you want to add multiplayer virtual computers to your own app, you can sign up on https://ift.tt/C7OKm8r , grab a free API key, and throw the provided embed URL in an iframe in your app. You can also play around more with the Three.js demo in our interactive sandbox: https://ift.tt/MbnyTkA If you have any questions or feedback, feel free to comment or shoot me an email at declan@hyperbeam.com.

Show HN: New UI for Ec2instances.info Hey HN, 10 years after the project began we have updated the UI for the cloud server comparison site known as EC2Instances.info. This refresh brings a sticky filter bar so you can scroll and see what filters are applied, a more compact navbar, and improved UX for comparing instances. I've also fixed numerous long standing UI bugs including: comparisons now load correctly on RDS and ElastiCache, sort by max ENI works, sort by RDS instance storage works, and all dropdowns have consistent behavior. For maintainers and contributors, all the frontend libraries are upgraded to their latest versions, https://ift.tt/U9qMZkI . Going forward, we are aware that the homepage size is quite large and have plans to address this. We have tried to be good stewards of this project and evolve it carefully.

Show HN: Brew.fm – Let bots discover new music on Spotify for you Use Spotify? This tool will automate your music discovery for you. Join here (100% perpetually free with no strings attached): https://brew.fm Some time ago, I built and showed HN[1] brew.fm, a tool helping artists remix each other’s work. It had been quiet, and I remembered how fun it was to work with the Spotify API, so I repurposed the tool to solve one of my own problems: missing out on new music of my favorite artists. I shared it on Reddit yesterday[2], and this seems to hit a spot for more people: so far 833 people connected their Spotify account. How it works: The tool simply shows your top 50 artists on Spotify over short, medium and long term, and checks those artists for new music. If you select a playlist, every artist involved in the tracks will be checked for new music, after which new releases are shown sorted by most recent release date. Here’s a video of me demoing the tool: https://youtu.be/Nh2Ognb4PgU . Enjoy! Very open to feedback.

Show HN: Pi-hole deployed at the edge on Fly.io and accessed via TailScale Hi, I just saw this tweet[^1] by @QuinnyPig that mentions accessing your Pi-hole while traveling thanks to TailScale and wondered how to deploy Pi-hole at the edge, instead of a home lab, for improved latency. My simple solution involves running it on Fly.io to make it easy to relocate anywhere, and embedding tailscale into the same firecracker VM (né docker container) to keep the infra dead simple and cheap. Naively deploying a publicly accessible DNS resolver is not ideal[^2] so the main constraint was to secure the VM by 1) keeping all public ports closed and 2) having Pi-hole listen only on the private network interface created by TailScale. It's all very straightforward but it's noticeably improved my bandwidth usage and page loading times across my laptop and mobile phone, so I figured I'd share. Suggestions for improvement are also welcome! [^1]: https://twitter.com/QuinnyPig/status/1558521941538983936 [^2]: https://ift.tt/Fj4H3kK... https://ift.tt/ERNu6j9 August 18, 2022 at 11:03PM
Show HN: We built an AirTag-like network for sensors that talk to your servers Hi, we’re Simon, Don and Dan, and we’re developing infrastructure for enabling Bluetooth devices that can communicate with your web backend (we’re calling it Blecon). Think your own AirTags network, but for sensors talking to your servers. We’ve got most of the underlying tech for the network infrastructure in place, and now have samples of a first manufacturer device that supports Blecon - a small rechargeable accelerometer tag. Not much live yet, but we put a summary of this first device and how it works in the link (plus you’ll find some early developer docs for the network infrastructure itself). TL;DR the tag logs timestamped motion and orientation events, and then sends the data using Blecon when phones come nearby. The data arrives at your specified network endpoint as JSON HTTP POSTs, so it is nice and flexible for integrating into any web infrastructure or framework you might be using. The customer use case for this device is actually monitoring when and how long equipment is being used, but motion and orientation can be used to infer a lot of things. Interested in what ideas you have for services you could build with just this first accelerometer sensor?! We’re still developing the network product, but interested in feedback, ideas, questions and use-cases. And if you are really interested we do have samples of this sensor so feel free to reach out if you have a service you’d like to try building with it! https://ift.tt/O3RvVCb August 18, 2022 at 11:29PM

Show HN: Learn words in a foreign language by typing I’m Brazilian and I made this tool for my brother to learn English. He’s also trying to learn the keyboard layout at the same time. So far he seems to be liking it and getting better. I manually built and open-sourced the dictionary on github, so anyone can contribute and add more languages. I’m doing that manually because I want to do that in the most easy and didactic way possible, with a very accurate translation and most used words. Ideally, in the next version, it will be using some sort of API or automated tool. I’m not sure how to make the dictionary work effectively because each description needs a very close translation (ideally as exact as possible). We’re not able to just copy words and descriptions because they won’t necessarily line up with the other language translations. We’re currently manually translating to be accurate, though ideally we can figure out a good way to scale this, if anyone has suggestions please let me know! https://ift.tt/1AslLvF August 16, 2022 at 11:16PM

Show HN: OxideDB – Teach PostgreSQL Database How to Speak MongoDB Wire Protocol Hey everyone! I have created a product that relies on MongoDB for a document store but doesn't really need any of the distributed features to really justify having a hosted MongoDB or DocumentDB instance. Now that we're trying to turn this into a product, we're seeing that some companies have a little bit of resistance around managing yet another database. Most of our clients already have and manage PostgreSQL in one form or another. I knew that PostgreSQL already offered first class JSON support, but I didn't want to rewrite the application data layer from scratch if I could avoid it. That's when I started researching if there was a "proxy" that would translate the MongoDB protocol - that I was completely ignorant about - into PostgreSQL. To my surprise there was nothing ready for production use but I found MangoDB that later on became FerretDB. I delved into the code and was in love with the idea. The team around is really nice, but I found that they had greater ambitions - they basically wanted to offer multiple backends, namely Tigris, on top of PostgreSQL. On the other hand, I have been waiting to find an excuse to delve deeply into the rust ecosystem but never really found something I was passionate about until I had the idea of challenging myself to see if I could learn about the protocol that MongoDB uses by relying on their public documentation and the hints I found on FerretDB. Fast forward 3 weeks and I have something I am almost comfortable on sharing yet super excited to get feedback on. It's in very early stages, and it's work from someone that is not yet super comfortable with the stack. Please don't be too harsh and keep in mind this is the beginning of a journey for me that I embarked out of pure joy on getting a tiny bit better on rust and making things click internally. Thank you for your time and if you would like to help me on this project please be more than welcome to reach out, either here, via email or directly on the GitHub repo. (heavy breathing before clicking submit :-) ) PS: I forgot to mention, but another thing I added to my toolbelt while developing this was about creating parsers. In order to transform MongoDB JSON to SQL queries, I ported an existing library from the MongoDB team from PEG.js to pest.rs! https://ift.tt/R74Uq9I August 15, 2022 at 10:43PM
Show HN: Anysphere, home for important, long-form conversations Hi everyone! I’m Arvid, cofounder of Anysphere ( https://anysphere.co ). With my two friends Sualeh and Shengtong I have been spending the last few months building a dedicated home for important, long-form conversations. We’re super excited to let the HN community test it out! We think that no existing platform for point–to-point communication prioritizes the conversations that you actually care about and that really matter. Instant messaging is filled with careless texts and stickers, email is filled with receipts and spammers, and physical mail, while better in those respects, is slow and cumbersome. None of the existing platforms are private enough. Anysphere attempts to fix this. It is private, secure, desktop-first and only allows people you added to contact you. Our whitepaper ( https://ift.tt/6v9KubI ) describes our privacy and security model in detail — in short, we protect all of your data and metadata against everyone (even our own server). Our client is fully open source: https://ift.tt/5HgsBhD . We deployed a small server to open up testing to everyone in the HN community. Instructions are here: https://ift.tt/v6qSQXM... .

Show HN: Bog Gobbler Word Game Two years ago my pandemic project was an online multi-player variant of Scrabble named Crossword Island Hopper where you capture territory by placing words on a board. It proved to be wildly unpopular. More recently I have been working on Bog Gobbler, which is a variant of Boggle where you capture territory by finding words in the grid. The territory-capture element is much more relevant in the multi-player game, but also affects the mechanics of solo games. This one is a little more popular and there is a daily solo challenge where everyone plays the same grid, with a global and personal leaderboard. You can go directly to the daily challenge at: https://ift.tt/t6FQYo8 If you know how to play Boggle the one thing you need to be aware of is that after the first word you find, all subsequent words must include at least one letter that you already "own". https://ift.tt/C6RDivX August 13, 2022 at 10:41PM
Show HN: Wordle but for Tweets Hey HN I built this simple app that grabs four popular tweets from the last 24 hours and removes a word from each, so that the missing words spell out a phrase. It's the player's job to guess the missing words. A key motive for building this was that, to be honest, I was finding much of the news and social media dialogue quite depressing. I thought that if a wholesome or inspirational phrase can be built out of these (often tiresome) tweets, then there would be something nice about that. The stack included GCloud scheduler (for daily Tweet scraping and automatic puzzle generation), Supabase (which, by the way, is fantastic) and Next / Vercel. https://www.birdle.art/ August 12, 2022 at 02:04AM
Show HN: Releese – Music business management software After working in the music industry myself as an artist (Midsplit) and as a label manager / employee (ChillYourMind, Strange Fruits) I noticed that the music industry has very antiquated tools that are often expensive and rarely updated. I had the idea to build a platform that could streamline the entire releasing process of music, we nailed it down to metadata management, royalty splits, landing pages generation, distribution to major stores and royalty collection (publishing + neighboring) rights. After building this with a small team for 18 months, we finally managed to create our vision with a surprisingly functional product. Our cloud infrastructure is based on Google Cloud and our app is 98% Typescript (Thank you Github) I would love to know how someone in or outside the music industry feels about the platform.

Show HN: Apprise v1.0.0 – A lightweight all-in-one notification solution I introduced Hacker News to Apprise back when it was just an experiment (and supported just 30 or so notification services at the time). Now supporting more then 85+ services and with a ton of built in features, I officially created it's first stable v1.0.0 release marking a major milestone for the project. Apprise doesn't compete with other notification services out there; instead it just acts as a proxy (or master switchboard) to support handling messages to them. It's a means of decoupling notification support from the systems that want to provide them. The idea is to adopt Apprise into your environment, and then you no longer have to worry about adding/removing support for new services as the come along and deprecating the ones that go away. The way it works is that every service out there maps to a `schema://credentials/?optional_configuration`. You just need to define the schemas you use, and then you can already use Apprise. Check out the list of the services available today here: https://ift.tt/QGFk1L3 Apprise is 100% open source (MIT Licensed). It has an acompanied API I built for those who want to centralize their configuration (found here: https://ift.tt/Wr7oUnS ). Some reasons you may also all find it useful: - It works perfectly with legacy servers (supporting even Python 2.7). So this fits system admins using older systems such as CentOS 6+ - It has a complete API that developers, devops, and administrators alike can leverage allowing them to control the notifications in their environments. - It supports configuration files allowing you to securely hide your credentials and map them to simple tags like `family`, `devops`, `marketing`, etc. There is no limit to the number of tag assignments. It supports a simple TEXT (https://ift.tt/D7qrx1n) based configuration, as well as a more advanced and configurable YAML (https://ift.tt/JQqs1g0) based one. - It sends all notifications asynchronously optimizing setups where there are many end-points to deliver to. - It supports inputs are of MARKDOWN, HTML, and TEXT and can easily convert between these depending on the endpoint. For example: HTML provided input would be converted to TEXT before passing it along as a text message. However the same HTML content provided would not be converted if the endpoint accepted it as such (such as Telegram, or Email). - It supports breaking large messages into smaller ones to fit the upstream service. Hence a text message (160 characters) or a Tweet (280 characters) would be constructed for you if the notification you sent was larger. - It supports file attachments too. So feel free to pass along an image, PDF, etc if the destination supports it. - It can easily allow you to write your own custom notifications and/or simply leverage Apprise as routing service to perform admin tasks for you. See here for more details: https://ift.tt/jI4cUlM - It has 100% code based test coverage. :) I hope to continue to add more services (and break 100+ supported services someday). I also hope some of you find it useful for your own project solution! https://ift.tt/pCa3eo4 August 7, 2022 at 10:21PM
Show HN: I made a cross-platform command-line music player called maestro It is built to work on Windows, Mac, and Linux, and was tested thoroughly on my Mac and lightly on my friend's Windows. Unfortunately, no one I know uses Linux. It works with WAV, MP3, FLAC, and Ogg Vorbis files. https://ift.tt/iz1jegP August 7, 2022 at 05:54AM
Show HN: A Gauss-Seidel solver visualization in a single HTML file Recently I was reading about fluid simulation and stumbled upon the Gauss Seidel method. I got interested in how it works and made a program that visualizes the method in action. I had the idea of making an interactive book-like thing for a while, so took this as a chance to do just that. Note that touch input doesn't work and the layout is targeted towards bigger screens, so it doesn't function properly on mobile. It was fun to make and I wanted to share it. Maybe someone will find it useful. Corrections and feedback are welcome. Technical Stuff - A single 1.7MB HTML file with embedded JavaScript and WebAssembly. You can save this single file and double click it to run. - A math typesetter from scratch in C that compiles/renders the equations in real-time (uses KaTex fonts and STB true type to rasterize the fonts). - Platform code is done using Sokol (tested on windows and web). - The UI is done using Dear ImGui (Most of the code is done in C++ to use ImGui without a wrapper except for the equations compiler). https://ift.tt/CcsSXgE August 7, 2022 at 01:51AM
Show HN: A link/news aggregator I am working on Hello HN, I'm building omegapedia.com, a link/news aggregator that combines features of multiple other sites. I started building this site because I often found some features lacking in other websites. As example: You can format you text to be italic, red, blue or to be a spoiler. Comments are not threaded and don't include any voting feature. Omegapedia uses upvotes and downvotes for posts but shows them as separate numbers. I styled the page in darkmode but added an optional lightmode as well. I added "Trust-Points" and a leaderboard to show the 5 users with the most points. Other noteworthy features are: -Comment replies. -Flairs. -Adding a bio to your profile. -Mention users in comments. -Ability to add a email address to your account. -Forgot-my-password function. -Link posts. There is no need to add a email andress to your account and you will never be forced to. The site works on pc and mobile. The site is very lightweight because there are no CSS or JavaScript libaries that will have to be downloaded first. There are multiple ways to sort the posts and a way to show the recent comments so you can join a current discussion anytime. There is no register barrier and you will be automatically logged in a muted guest account. I am very interested in feedback and if you have any questions or comments please let me know, thank you! ======== Join me on omegapedia! https://ift.tt/FZcmAV5 https://ift.tt/ixzgcrF August 5, 2022 at 10:25PM
Show HN: I created a browser automation tool I created this tool a few months ago to automate some of my tasks. I use it to collect prices and files and to get notified when something changes on certain websites. The task runner uses Playwright. I'm not sure if it can be useful to anybody else besides me :) Any feedback is welcome. https://ift.tt/HI5cLJx August 5, 2022 at 11:28AM
Show HN: Penumbra, a perceptually optimized color palette based on natural light For this palette, I used recent advances in color science, which made perceptual design more accessible, to choose a set of colors (mainly for syntax highlighting) that have uniform luminance for less visually uneven, fluidly readable code, but at the same time maximally distinguishable hue and chroma. The background colors are based on natural (sun-)light and shade for a more pleasing look than equally neutral greys. For much more detailed info, including the construction, check out the repository. There’s also already a (bare-bones) VSCode extension, linked in the repository, but it could admittedly use more informed distribution of colors over tokens, language specific highlighting and perhaps more opinionated use in UI elements. https://ift.tt/ghVoCe6 August 5, 2022 at 02:53AM
Show HN: Butt Mover - A butt triggered productivity and health improvement game Productivity timers needed to be triggered manually before each task, Making it a chore by itself, Often leading to us not using them after a while and They don't take health into consideration. Health timers are intrusive, Even then they are not always accurate and They don't take productivity into consideration. Butt Mover addresses those problems by using a butt trigger for automatically starting the productivity timer when we sit on the chair before our workstation and a break timer which reminds us to take a walk automatically when we get up. Butt Mover also incentivizes its usage through a Game. When the health(tasks/breaks) reaches zero its game over. I've been iterating different forms of Butt Mover over past two years and released the web application earlier this year(After feedback from several HN users). Today I'm making the core application open-source as I've committed myself to make the Health & Education applications I build open-source. I hope you'd use Butt Mover for yourself and build Butt Trigger for others to improve productivity and health. Feedback and contributions to improve the project is appreciated. https://ift.tt/pugkDzr August 5, 2022 at 12:25AM

Show HN: MutableAI (YC W22) – Copilot Alternative for VS Code Hi HN, We’re MutableAI (YC W22) ( https://mutable.ai ). Our mission is to reduce the time and cost to create high quality code using AI. We have worked at the full gamut of companies ranging from startups to big tech and have gotten the sense that many of the rote aspects of software development could be made easier, freeing up precious mental energy. Devs love Copilot, but autocomplete is just one of many ways that AI should make programming easier. We’re taking a more comprehensive approach to developer tooling that bundles Copilot-like autocomplete with documentation, custom AI instruction, and some early refactoring capabilities (Python only) in one extension. We currently support Javascript/Typescript, Python, Go, and Rust, with more coming soon. Overview (w/ bg music) [3]. In addition to autocomplete, which can be triggered either automatically or manually, we can add documentation to all your methods in a Rust file, or you can ask the AI to insert missing imports in a Python file. In some cases we can get really sophisticated and ask it to program a game from scratch or update your REST interface to accommodate a new data payload. We use a combination of AI (e.g. OpenAI codex) and AST transformation / metaprogramming techniques on the backend. We are also working on providing other backend solutions for varying needs, including on-prem deployments. We soft launched our product with a small cohort of users and want to welcome more of you to our pilot beta. We hope you enjoy the product and look forward to learning from you. We are currently in an extended free trial phase for early adopters and plan to keep a free tier for solo devs and open source contributors. We also offer a generous discount to startups. For enterprise please reach out to info@mutable.ai We want to thank our very earliest users and invite the HN community to try the product installing it via the VS Code marketplace [1] and email us directly with feedback or feature suggestions (support@mutable.ai).

Show HN: PiBox: a tiny personal server for self-hosting Heya HN! We've built a Raspberry PI CM4 based SSD NAS for home hosting. We built it as a part of KubeSail.com - which is a platform aimed at making self-hosting easy and at making the technical bits (tunneling, backups, updates, etc) as easy as possible. You may have seen plans for this about 9 months ago on HN, but we're finally in full production! I'll be booking tickets to fly out and help assemble the 2nd batch in a few days - we're effectively a two person computer company, which is a lot of fun and a crazy amount of work. Our mission is to make home-hosting a website, an app, or just personal photos a reasonable alternative to SaaS products. https://pibox.io/order August 2, 2022 at 04:34AM
Show HN: Personal productivity workspace for busy people We're building an app that helps people manage their schedule, tasks and notes all in one place. The goal is to create a workspace, where people can manage their various priorities, both personal and professional, see a single schedule combined of all their calendars and manage their days without switching between multiple apps. At the moment we've implemented Google calendar synchronisation, basic tasks and notes. Also Emery has some things we really wanted to see in other apps – private notes for meetings, categories that can be used to group tasks/notes/meetings together, weekly productivity reports. Happy to hear any feedback and answer any questions! https://emery.to/ August 2, 2022 at 03:12AM
Show HN: ProxSNI, a transparent HTTPS tunnel for self-hosters I'm self-hosting my stuff, and pay dearly for a fixed IP from my ISP. Either you do that, or you rent a VPS and set up a somewhat complicated scheme to forward traffic to your home, or maybe you feel like giving Cloudflare access to all your files on the way to you [1]. Maybe that's too much, and you change again to a VPS setup. Well I felt like an option was missing: An SNI-sniffing reverse proxy. That's exactly what ProxSNI [2] is. Using the open-source (!) client, all HTTP and HTTPS traffic is forwarded to you, without breaking any encryption (since SNI was never encrypted in the first place). That means your traffic is always yours, and ProxSNI just forwards it to you. You are in charge of getting a domain and setting up your server at home, we just send you your traffic. Where other mail men in this area will open your letter to make sure nothing bad is inside, we simply read the address on the envelope and deliver it, and put some pride in letting you decide what's best for you. I hope you'll try our service free of charge for the duration of this beta-launch. [1] https://ift.tt/vRh30rt [2] https://proxsni.com https://proxsni.com/?hn August 1, 2022 at 09:09PM
Show HN: Rentaflop – Render your Blender projects without sacrificing quality Hi HN, My name is David Sokol, and I'm the founder of rentaflop (https://rentaflop.com). We're a crowdsourced render farm aimed at making Blender rendering fast and affordable. If you've used Blender, then I'm sure you've experienced the pain of waiting around for your animations to render. You've probably even had to sacrifice the quality of your work to reduce your render times. I've been there too. If you're like me, then you're also disappointed with the alternative solutions: spending thousands of dollars on graphics cards or using prohibitively expensive cloud render farms to get fast render times. Our solution to this dilemma is to leverage low opportunity cost hardware from around the world to allow Blender artists to render their projects quickly, affordably, and without compromising on quality. Since most graphics card owners aren't utilizing their hardware to do valuable work 24/7, we provide them with a way to make money without lifting a finger, while lowering the cost curve for 3D rendering. We're currently doing a private beta. If you'd like to get early access, check out our site (https://rentaflop.com) and join the waitlist. If you're a graphics card owner who wants to help Blender artists while earning money, reach out to support@rentaflop.com and we'll help you get set up. Please leave a comment below, we'd love to hear your thoughts :) August 1, 2022 at 04:29AM
Show HN: Ordinary Puzzles, a free puzzle game inspired by Picross and Sudoku Hello hello HN! I wanted to share with you Ordinary Puzzles, a little puzzle game I designed and developed in my free time, inspired by Picross and Sudoku. I already posted it here ages ago, but I wanted to share it again now that I updated it to also be playable online as a Progressive Web App. Ordinary Puzzles is open source, is built with React Native, and it’s available on the mobile app stores, on the web (as a PWA), and as an Electron app. Hope you give it a try! (Please don’t skip the short tutorial :P) https://ift.tt/dNzyXMH P.S.: The puzzles come from https://ift.tt/pWqgL0b (the author is credited and has been contacted before using them). https://ift.tt/xO79KDp July 31, 2022 at 11:01PM
Show HN: I've been making JavaScript sandbox alone for 6 years Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work. https://playcode.io/ July 31, 2022 at 09:57AM
