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...

Show HN: Chunk – Code sandbox for back-end devs Chunk co-founder here. We spent the last 2 weeks building this to scratch our own itch: As developers, we often have problems that could be solved just by running a few lines of code. Sometimes, running this code on your local machine is fine. But other time, the code need to run automatically reacting to external events or to run continuously, which means, it needs to run on a server somewhere. So now, you have to find a cloud provider, to package or build the code and finally to deploy it. All of that for what could be literally be 4 lines of code. We couldn’t find an easier way to do this, so we built it. Chunk is an all in one web editor (think of the codesandbox experience) that allows you to write, deploy and run a piece of code in the cloud from a variety of triggers: HTTP, WebHook, manual or scheduled (cron). No setup, no build, no deploy. Chunk makes you go from idea to code running in the cloud in seconds. Let me know what you g...

Show HN: TensorDock Core GPU Cloud – GPU servers from $0.29/hr Hello HN! I’m Jonathan from TensorDock. After 7 months in beta, we’re finally launching Core Cloud, our platform to deploy GPU virtual machines in as little as 45 seconds! https://ift.tt/EelWLCI Why? Training machine learning workloads at large clouds can be extremely expensive. This left us wondering, “how did cloud ever become more expensive than on-prem?” I’ve seen too many ML startups buy their own hardware. Cheaper dedicated servers with NVIDIA GPUs are not too hard to find, but they lack the functionality and scalability of the big clouds. We thought to ourselves, what if we built a platform that combines the functionality of the large clouds but made it priced somewhere between a dedicated server and the large clouds? That’s exactly what we’ve done. Built to make engineers more productive. We have 3 machine learning images so you can start training ML models in 2 minutes, not 2 hours. We provide a REST API, so you ca...

Show HN: Looria – A product (re)search engine About 1.5 years ago, I introduced my review aggregator BuyForLife on Hacker News, where it became the #8 most upvoted Show HN project of all time[1]. The idea of helping people to make better purchasing decisions continued to chase me over the last year. Here are some stats that illustrate how important online reviews are: • 90% check online reviews as part of their online buying journey • 43% visit 5-10 websites to research a product • 75% spend more than a day doing research before buying a product The top frustrations with the current process are: • Google full of SEO spam and Ads • Fake reviews • Fragmented trusted sources • Inconsistent information across sources Thanks to the recent advances in NLP (transformers, GPT-3, etc.) it became possible to solve these problems at scale, so I decided to team up with my co-founders Johnny and Tavis to build https://Looria.com . We aggregate and summarize the most trusted product reviews on the w...

Show HN: TypeScript query builder with full type inference Hey HN! Colin here - a TypeScripter, open sourcer, and engineer at EdgeDB. As the creator of Zod and tRPC, I'm interested in designing tools/APIs that use type inference and generics to make life easier for devs. This query builder represents another step in that direction. We set out to build an EdgeQL query builder that can express queries of arbitrary complexity (EdgeQL has feature parity with SQL, roughly) and infer the static type of the query result. We introspect the database and generate a schema-aware client that represent any query, including ones that use built-in functions, operators, string/array/tuple indexing, aggregations, conditionals, type casting, subqueries, computed properties, etc—things most ORMs can’t represent. This post mostly discusses the API design, which I think will be interesting regardless of familiarity with EdgeQL. I’d love to see some of these ideas bleed into future generations of TypeSc...

Show HN: PickCode – An educational coding environment for students after Scratch PickCode is designed for use on desktop and tablet, and supports creating chatbots, visual designs, and 2D games. There is plenty of functionality missing - you can't add media to games for instance, but the current version shows off the foundation of what I'm aiming at. I taught myself to code using MIT's App Inventor, so I have an enormous respect for block based languages like App Inventor, Scratch, Snap!, MakeCode, etc. PickCode is my attempt at adding options for students who want to learn more about programming without making the jump to text, or as an alternative to block coding for beginners coming to programming at an older age. The visual language is meant to lower the barrier to entry to coding but the far more important aspect for me is giving students the ability to make things they're proud of as quickly as possible.

Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So I did just that =). I find hexagonal pipes a bit more difficult than the square variant because there's a larger variety of possible tile shapes. For an extra challenge I implemented wrap mode where the board can connect to itself (right to left and top to bottom), so there are no convenient outer walls to start from. The site is...

Show HN: Zazow – Generative Art Toy (fractals, spirograph, satori, etc.) Im finally ready to share a fun side project that I've been working on. For 20 years, Ive been fascinated with Mandelbrot fractals. Back in the day, I made a MacOS9 app that rendered them, and I missed it. So, I decided to bring it up to the modern age and build a website to explore this and other similar fractals. In the process, I discovered some other types of generative art that looked fun, so I made those too. One is a spirograph, another is similar to an old AfterDark screensaver called Satori (anyone remember that?). Others draw paint splatters and random squiggly lines. The user is given a bunch of interactive settings to control how the artwork is generated. Im hoping to continue adding different styles of generative art to the website over time. Its a fun, relaxing project to work on and I hope other people enjoy using it to create pleasing images. https://www.zazow.com July 22, 2022 at 10:44PM

But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to write all the firmware from scratch and even designed my first PCB, resulting in a finished (though not very polished) handheld CHIP-8 console. For those curious, the GitHub repo also has links to my dev blog about the project as well as a build guide. Thanks for looking! https://ift.tt/sSJAcBN July 20, 2022 at 03:12A...

Our ETL pipeline is already hundreds of thousands of lines of complex code in Perl and shell scripts. Adding another layer of Python on top of this might make it difficult to maintain.

Show HN: Ex Platform for SWEs Hey guys, just sharing this project that I've been working on. Let me know what you think. This idea came primarily from my own experience in the software industry. After a while, I was feeling discouraged by my job, mostly because I felt expendable (like a code monkey), burned out, and had unchallenging work. It felt like the employers I was working for didn’t have an idea of what was going on or how their employees were feeling. They would talk a lot about the technical challenges, but never did we talk about any mental/emotional challenges. So I started thinking about what could be done to mitigate this problem and came up with this solution. An employee experience platform that tracks multiple psychological dimensions (specifically customized to track problems that can be faced in a software engineering environment) and gives the managers some insights into their teams/employees. I'm still currently working on the MVP but would love to hear wha...

Show HN: Hacker News Mods - A collection of tools/mods for HN Hey HN! I built Hacker News Mods as a place to collect any tools or sites related to HN. We just started building one mod/tool for HN per week, and I thought it’d be a good idea to showcase all of the tools we’ve created, as well as tools that others have created as well. The site is pretty scrappy, so any feedback is appreciated! Also, please submit any projects that we don’t already have listed! Thanks, Jarren https://ift.tt/CdZrS8u July 16, 2022 at 02:09AM

Show HN: Eesel – Federated search without API integrations Hey there! Amogh here from eesel ( https://eesel.app ). eesel filters your browser history to show the docs you need for work, right in your new tab. You can see recent docs, filter by app or search by title or content. We're trying to solve a pretty universal problem. Everyone's work is spread across apps - there's a project brief in Google Docs, issues in Jira, a mockup in Figma, PRs in GitHub - and with this kind of sprawl, it can be a game of trial and error to find the links we need to do our job. Trying keywords in the address bar only works if we remember the title and it's specific enough, search in apps can be slow and noisy, company "knowledge hubs" in Confluence or Google Drive are usually not up to date, and we ultimately just ping each other on Slack to find things. I was struggling with this acutely as a PM at Intercom, and it felt ridiculous that I could search the web faster than my com...

Show HN: Mapedia.org – A Crowdsourced Learning Map Hi HN! We're happy to announce the launch of Mapedia.org, an open source crowdsourced learning map! Mapedia is a new kind of learning platform at the crossroad between Wikipedia, Google Maps and Khan Academy: a learning map built collaboratively to support online learners to learn any topic seamlessly. We built an interactive learning map of topics to be able to visualize the different fields of knowledge, what concepts are included in them and how they relate to each other. This allows for curiosity based exploration, identifying knowledge gaps (unknown unknowns) and figuring out what to learn next (and in which order). For each topic you can then find community and expert curated resources, learning advices and smart recommendations in order to learn as efficiently as possible. We want people to spend time learning rather than figuring out how to learn, and in particular to empower self-directed learners. The idea came out of the...

Show HN: Tweedle – A Wordle game for profiles and tweets on Twitter Hey everyone! I wanted to share a game that myself and a couple other colleagues hacked up called Tweedle. We wanted to try something different in the genre of wordle clones, so we decided to build a game that algorithmically generates daily wordle puzzles for any person/profile on Twitter. The idea is that you can play someone’s tweets, guessing a word inside the tweet using wordle style gameplay. If you have an active Twitter profile, the game will generate a puzzle for your profile; this enables anyone on Twitter to have their own wordle game! Here is a game for a popular hacker news bot on twitter: https://ift.tt/bC3Qr2h If you have a twitter profile, you can play your own game by navigating to https://ift.tt/wJvCUXs The game runs on a pretty standard AWS stack. The backend is designed to dynamically generate puzzles for any new profile. It uses an idempotent heuristic that both selects the daily tweet and daily wo...

Show HN: Payload, X-Platform Desktop App for LAN File Transfers [Tauri/Rust, Go] Hi HN. I built Payload to make file transfers easy for less-technical users who need large/fast transfers, so I have focused on auto-discovery, drag-and-drop, visually distinct device icons. It's using Tauri (an "Electron alternative" built on Rust) which keeps my binaries small and bundles to .msi, .dmg, .deb and .appimage. No CLI, iOS or Android support (yet). The network stack is a separate binary written in Go. It uses mDNS for local network discovery and TLS over TCP or Quic, with a public Ed25519 keypair for each device. The protocol is ad-hoc and symmetrical control stream using JSON and binary data streams. Planning to open source these parts eventually.. Transfers should saturate the local network link. It reaches ~116 MB/s wired at my home, but if you have a >1000 Mbit link, I'd be curious to see how much speed you can squeeze out. See also: https://ift.tt/QjpswZn https://ift...

Show HN: Old News – News that gets better the *less* you read it I’ve always wanted a news app designed for people who don’t stay up-to-date daily. That pays attention to when I check-in and what stories I’m aware of and adapts to me. You see, I’m not a good “follower” of the news, and I “catch-up” fairly infrequently. When I do, I want to see the most important things I’ve missed in the meantime, not today’s top stories. I’d like to emerge from my metaphorical cave after a week, a month, or longer, and quickly see what I missed. That’s Old News. I built it for myself, but if you’re like me (statistically, you probably aren’t!) you may like it too. It is quite simple. Swipe to see recommended Hacker News stories and the app keeps track of what you’ve seen. When you come back you’ll see the top stories you haven’t seen yet, with a slow exponential decay of the score over time (a big story from yesterday is still more interesting than one from last month). In the future, I’d love to expl...

Show HN: Image Compression and Resizing Tool When I'm working on my niche sites, I often have the problem that I need to resize my images and compress them so I get the best performance. For my use-case I needed 2 different tools + renaming them manually to get the image I want to upload onto my niche site. I'm a programmer and hate tedious and repeating work, so I decided to make a tool for my workflow: https://www.canvar.io Right now the functionality is very basic: You can upload an image, select an output format, resize and rename it. When you click on "Compress & Download", the image gets compressed and - surprise - downloaded to your computer. Now I would love your feedback on the tool. What can I make better? What did I do good, what sucks? July 13, 2022 at 12:26PM

Show HN: Kreya, a Postman Alternative Hi HN! For over a year we've been working on Kreya. At first, it only supported gRPC, because the alternative tools (eg. BloomRPC) were very limited in their functionality. Since then, we have added many features, trying hard to keep the UI clean while still supporting advanced use cases. Yesterday, we released Kreya v1.8, which added support for REST! In our opinion, Kreya is a good alternative to the existing tools out there. Sure, it may not support all the features that Postman has. But we think that Kreya has some innovative approaches (eg. authentication or API importers) that users may find interesting. https://kreya.app/ July 12, 2022 at 12:35PM

Show HN: Lldap, a Simplified LDAP Server Hi everyone! For the past year I've been working on a simple LDAP server for user management, targeted at self-hosted servers. The idea is that OpenLDAP is a pain to install, configure and manage, and on top of that you need a frontend if you want a web UI. LDAP instead provides a minimalistic LDAP server that supports the subset of LDAP needed for user management and authentication, with almost no configuration required, and a nice UI/API in front of it. We just released version 0.4 (and 0.3 actually) and it should now be stable enough to use it yourself! We've had some people using it for tests as well. https://ift.tt/Afhea6O July 11, 2022 at 02:59PM
