Show HN: AirQL: An Airtable API with OAuth2 access control and permissions https://ift.tt/b5A08Re

Show HN: AirQL: An Airtable API with OAuth2 access control and permissions Hey there! At our company, Bit Complete [1], we use Airtable a bunch for managing operations. We really like how easy it is to throw up a form to collect information, or to build automations for offline processing like aggregations. One challenge we kept running into was how to build more complicated interactive apps using the API, while maintaining fine-grained access control to Airtable data. Airtable ties identity to API access control via API keys, which makes it very hard to build apps with realistic access control needs. So we built AirQL! [2] It’s a utility layer between Airtable’s API and custom/internal web applications that supports Google authentication and flexible access control. We’ve found that it makes it practical to build simple, useful internal apps, that still benefit from everything else Airtable has to offer. If this sounds interesting, check out the docs [3], try out the product, and let u...

Show HN: Jsonnet Course Online https://ift.tt/0k5Uty4

Show HN: Jsonnet Course Online Hi HN! I'm usually a lurker here, but I wanted to share this: I'm an enthusiastic user of Jsonnet[1] to flexibly generate JSON and YAML files (eg for kubernetes configurations). I wanted to spread awareness of Jsonnet and made a course on Udemy. The first 1000 students enrolling within 5 days with this link get the course for free: https://ift.tt/mBPAlf0... I hope you enjoy the course (I'm interested in your feedback!) and if it makes you start using Jsonnet it will be mission accomplished :-) [1] https://jsonnet.org/ https://ift.tt/zKHkCRr September 30, 2022 at 12:49PM

Show HN: Red Goose – Convert your website to mobile app https://ift.tt/rYRah1t

Show HN: Red Goose – Convert your website to mobile app Hi HN! We're Sonica, Marvin, and Satie, and we are building Red Goose (https://goose.red). Red Goose is a web app to mobile app conversion engine that produces ready-to-publish apps for the app stores using GitHub repos. There was a discussion on HN a few weeks ago about how a developer shaved off almost half of their native app's code without losing functionality [1]. Our launch today is a direct outcome of that thread and, moreso, in the context of this comment [2] and this one [3]. Paraphrasing the context below: > "Fastmail is the only email/calendar app with a reasonable size (just 20MB)." Followed by: > "… EDIT: just realized the app is a web view. Sigh." As someone who has been into mobile app development since 2010, the comments above read like a punch to the gut. We grew up believing that the native experience was better than the web! It took a while to admit, but the web, it appears, has...

Show HN: Restapp.io – SQL Data Modeling Tool in No/Low Code https://ift.tt/2HGOhoz

Show HN: Restapp.io – SQL Data Modeling Tool in No/Low Code Hey all! We've been working on RestApp V1 and this is our first time posting it on HN. It's an No/Low Code data modeling tool that enables you to build & maintain data pipelines with a visual programming interface. We don't store your data but we compute them through Apache Spark for query speed & efficiency. Here's some features: `Connectors: Connect to any source and destinations (DB, DWH and SaaS Applications). We currently support MongoDB, Snowflake, BigQuery, MySQL, MSSQL, SFTP (JSON, txt, csv, excel files supported), Hubspot, Stripe, GDrive (JSON, txt, csv, excel files supported). `Pipeline: Visual Programming Interface where you drag-and-drop SQL, NoSQL & Python functions instead of writing them to create a query and debug it easily. `Automation: You can automate your data pipeline (Job) through a scheduler. `Domain: Think of it like a workspace in which you can share securely your connectors...

Show HN: KaithemAutomation, the home automation system for coders and artists https://ift.tt/RSuxi7s

Show HN: KaithemAutomation, the home automation system for coders and artists I've talked about this one on Reddit a bit, and I think it's finally about ready to talk about here. I started this project around 2013 for internal use, and GPL licensed it because I have no desire to own my own software business. Kaithem is, for the most part, somewhere between a SCADA and a Home Assistant clone, heavily focused on easy deployment with minimal tinkering. It allows for Python code based if-then events you edit via the web, along with web-editable HTML dashboards, but also includes loadable modules for more point-and-click style editing. One of these is Chandler, a scenes/cues manager that includes a simple visual scripting language inspired by ladder logic. It saves everything you create in Git-friendly plain text files, and is meant to integrate well with a linux system, with convenience features like using the user account username/password to log in. Device drivers created via an ...

Show HN: Ponzu – AI Generated Textures for 3D models https://ift.tt/D5pYwb7

Show HN: Ponzu – AI Generated Textures for 3D models Hey everyone! We just launched Ponzu, an AI-powered prototyping tool that generates tile-able textures for your 3d models. You can give it any prompt, choose an art style, and get an interactive playground to preview and export your generated textures. What you get with Ponzu: 1. AI-generated texture assets 2. Normal, AO, specular, and displacement maps for each texture 3. Adjustable 3D previews in the browser 4. Customizable styles and shareable links We're excited to use AI to supercharge artist and dev workflows, and we're looking forward to feedback on Ponzu! Ponzu is free to use, but we have limited capacity to run GPUs. As a heads up, there might be times when requests queue up and take a few seconds to process. We also launched today on product hunt: https://ift.tt/n93XZG8 https://www.ponzu.gg/ September 27, 2022 at 11:20PM

Show HN: Get conversational practice in over 20 languages by talking to an AI https://ift.tt/AO92kWc

Show HN: Get conversational practice in over 20 languages by talking to an AI Hi everyone, Let me introduce you to Quazel, where we want to enable people to talk their way to fluency. We have all tried various language learning apps and tools, however, one aspect of language learning current services are really bad at is conversational practice. You might get a chat-like interface, but in the end, the conversation partner will only respond with a predefined "if the users say X I say Y". With Quazel that's completely different. In completely dynamic and unscripted conversation you can talk about pretty much anything you want. For example, you can try ordering food at a restaurant and even hold a philosophical discussion with Socrates. Additionally, you can analyze the grammar of your responses or use hints to help you out when you get stuck. We want to change how languages are learned from a grammar-centric approach to a more natural, conversation-focused one. https://ift....

Show HN: Clammer – share and discuss article excerpts with friends https://ift.tt/YWHGCav

Show HN: Clammer – share and discuss article excerpts with friends Clammer is a social platform for sharing and discussing excerpts from online written content. It's like Twitter but every post and thread stems from the facts, quotes, and insights you collect online, all tied back to the source. In fact, you can have a whole conversation without ever writing a single word. I made this because I was tired of rehashing vague opinions, the real juicy conversations are in the details. Would love to know if this resonates with anyone; any and all feedback is hugely appreciated. Demo: https://www.youtube.com/watch?v=ZU-4uMcNiGk https://clammer.io September 26, 2022 at 05:35AM

Show HN: Outstatic an open source CMS for Next.js https://ift.tt/SdhclAM

Show HN: Outstatic an open source CMS for Next.js Hi, I've been working on a new project for a couple of months and I'm close to launching it. It is called Outstatic, I created a landing page for it. Sing up to the waitlist to be notified when it comes out. Features include: Open source Host for free Keep your data 5 minute setup (5 minutes to live!) The CMS was built with Next.js and uses Github and Vercel as its main hosting platforms. Full site with examples and documentation coming soon. Feedback on the idea and the current landing page is appreciated. Thank you! https://outstatic.com September 25, 2022 at 10:47PM

Show HN: I build a terminal-friendly static file server https://ift.tt/RSxkFV6

Show HN: I build a terminal-friendly static file server If you ask why there was .hg and .hgignore in a Git repository, it's because I completely forgot this project is my first ever project using Mercurial as SCM. As such, I foolishly `git init` the repository and have to update both .gitignore and .hgignore to finish the changes. You can also see the Mercurial version of this thing at here: https://ift.tt/Br4yKsp https://ift.tt/2GybZM3 September 24, 2022 at 02:45PM

Show HN: An AI image generator for blog posts https://ift.tt/izVOpmC

Show HN: An AI image generator for blog posts Hi there, I see many bloggers use stock images for their blog posts (as featured images or as in-post images). I thought of something and started trying to use AI to replace those images. I built a small tool for this so others can also test it out. It takes text content (ideally, the blog post intro in case of a featured image or the text content about whatever you want the image about) and gives you an image. It works for me but I am still testing this. How about you guys? https://ift.tt/5ewT047 September 23, 2022 at 04:21PM

Show HN: A Stable Diffusion desktop frontend with inpainting, img2img and more https://ift.tt/Jsxgh6D

Show HN: A Stable Diffusion desktop frontend with inpainting, img2img and more I was frustrated with laggy notebook stable diffusion demos. Plus they usually didn't have all the features I wanted (for example some of them only had inpainting and some only had img2img, so if I wanted both I had to repeatedly copy images between notebooks). So I made this desktop frontend which has much smoother performance than notebook alternatives and integrates image generation, inpainting and img2img into the same workflow. See a video demo here: https://ift.tt/41xgdOJ... Features include: * Can run locally or connect to a google colab server * Ability to erase * Ability to paint custom colors into the image. It is useful both for img2img (you can sketch a rough prototype and reimagine it into something nice) and inpainting (for example, you can paint a pixel red and it forces Stable Diffusion to put something red in there) * Infinite undo/redo * You can import your other images into a scratch p...

Show HN: An async traceroute(1) implementation in Rust https://ift.tt/QYcG9EM

Show HN: An async traceroute(1) implementation in Rust I wrote a minimal traceroute(1) clone that leans on asynchrony to reduce the time spent tracing a route. Underneath, it uses ICMP to do its job. The plan is to add support for UDP tracing and a path maximum transmission unit discovery mechanism. Comments and suggestions are welcome! https://ift.tt/98HunTS September 23, 2022 at 11:52AM

Show HN: Venice – open-source Plaid to Postgres in minutes without code https://ift.tt/GwYXgfk

Show HN: Venice – open-source Plaid to Postgres in minutes without code Hi HN! Tony & Ali here, we are super excited to introduce Venice - an open source financial data integrations platform. Our MVP is getting financial data from Plaid into your postgres database in under 5 mins. We met while building our own respective fintechs. We noticed how much developer time went into setting up and maintaining the infrastructure rather than actually building the fintech itself. In Tony’s last project Alka for instance, the engineering team spent 30%+ of time building and maintaining the data connectivity and pipeline rather than the core work of accounting. What we wish existed is a Segment / Airtable for fintech, letting you get financial data from wherever they are produced to anywhere they are useful. We think the most basic version is a Plaid to Postgres database connector with a self-service portal where your customers can add / remove / repair and manage their financial connections. T...

Show HN: Big Picture” project management for software developers https://ift.tt/UFtBMST

Show HN: Big Picture” project management for software developers We got tired of not being able to accurately answer "When will this be done?" and "Will anyone be required to work overtime on the current schedule?", or spending too much time in meetings and standups trying to answer those questions. Just opened up for beta. Would love some opinionated developers to guide future improvements (or feedback on the general idea). https://ift.tt/PxNX5yv September 22, 2022 at 10:04PM

Show HN: I Built 0xFast Stream – 100x Faster Ethereum Block Downloads https://ift.tt/x1nQ3jw

Show HN: I Built 0xFast Stream – 100x Faster Ethereum Block Downloads Getting web3 data out of Ethereum nodes or node services is excruciatingly slow (at least days if not weeks). I had wanted a way to just download the blocks quickly since I started exploring the web3 space. Took me a bunch of trial and errors to get to a way where I can parse all the blocks since genesis within 12 hours. But, instead of moving on to the next thing, I put this service together over the last few days, so everyone can benefit. https://ift.tt/P75Kplf September 22, 2022 at 08:39PM

Show HN: Copy link to highlight alternative for Chrome with multiple highlights https://ift.tt/25av3nx

Show HN: Copy link to highlight alternative for Chrome with multiple highlights Hi HN! I made a Chrome extension called Save Link to Highlight. It makes it easy for those who want to share multiple highlights on a page without any hassles. It uses the same built-in technology in Chrome as Copy link to highlight. So, the link you share will highlight text on the page once it's opened in most browsers without 3rd party tools. Ex. https://ift.tt/CNjHGv9 It's free! No account or signup needed. Some everyday use cases • Share an article with a friend that also has the parts you found most interesting highlighted. • A teacher can share key points they highlighted for students on a Wikipedia page. https://ift.tt/UWG8efy September 22, 2022 at 05:34PM

Show HN: Check if anyone else submitted a thing to HN and then submit it https://ift.tt/DVQxm1b

Show HN: Check if anyone else submitted a thing to HN and then submit it Hi HN! I made this for myself to submit stuff to HN without copy pasting. I also recently added a thing to check if anyone else already submitted the link to avoid posting duplicates. I find it pretty useful myself and I hope you do too! https://ift.tt/dpJsw68 September 22, 2022 at 03:18AM

Show HN: I put my résumé into a DOOM WAD https://ift.tt/me1CF8l

Show HN: I put my résumé into a DOOM WAD I was tired of of old and busted PDF résumé, so I thought why not try adding some of the information into a DOOM WAD instead. As a way of conveying information to an employer it's terrible, but if it takes longer than 30s to play, it might be looked at longer than the average résumé. https://ift.tt/fPvKFiw September 21, 2022 at 07:28PM

Show HN: The simplest drum pattern composing algorithm I could come up with https://ift.tt/v9XMLby

Show HN: The simplest drum pattern composing algorithm I could come up with Hi there, my name is Jay. Making music and writing software have probably been the two biggest pleasures of my life -only after my family. My team and I recently started a long journey of trying to completely change the way people create music, and as it usually happens with any long journey, it all starts with small steps. One of those small steps was to build https://drummy.io, or "Dummy Drums," a very simple yet useful drum machine that stores the entire drum pattern in the hashtag of the URL. There is no backend. Fully served by a CDN. If you wanna learn how to build your own drum machine in Javascript using the WebAudioAPI, here's an amazing read: "A tale of Two Clocks." (https://ift.tt/g5FrTJR). Also, check Howler.js (https://howlerjs.com/), a rock-solid library with a great community. Anyway, not long ago I noticed the dummy drums site hasn't been getting much traction, but I ...

Show HN: Hurl, test APIs with plain text and libcurl https://ift.tt/kCx1yT5

Show HN: Hurl, test APIs with plain text and libcurl Hi, We're happy to release a new version of Hurl [1]. Hurl is a command line tool powered by curl, that runs HTTP requests defined in a simple plain text format: # Get home: GET https://example.org HTTP/1.1 200 [Captures] csrf_token: xpath "string(//meta[@name='_csrf_token']/@content)" # Do login! POST https://ift.tt/vbfTasC X-CSRF-TOKEN: HTTP/1.1 302 Hurl can be used to get data like curl, or as an integration testing tool for JSON/XML HTTP apis / HTML content. Requests can be chained, and one can add asserts on response headers, cookies and body. For instance: GET https://ift.tt/yO7BLVH screencapability: low HTTP/1.1 200 [Asserts] jsonpath "$.validated" == true jsonpath "$.userInfo.lastName" == "Herbert" jsonpath "$.hasDevice" == false jsonpath "$.links" count == 12 jsonpath "$.order" matches /^order-\d{8}$/ You can see more samples in the documentati...

Show HN: Figr.app – a multi-user, notepad style calculator (desktop app) https://ift.tt/MXjY9Ru

Show HN: Figr.app – a multi-user, notepad style calculator (desktop app) Hi all, just posting an update to my previous Show HN, where I announced a side-project I worked on which was a (web version) of a multi-user, notepad style calculator: https://ift.tt/I53yuWO After a couple of user requests (and having a good think about it) I decided to migrate the web UI to create a Mac and Windows desktop app. After using it a little bit, I feel this is a much better experience than the webapp, and reduces a lot of the friction if I wanted to run a few small calculations. You can find the download links below: https://ift.tt/Fk7vDiU For context, Figr was a side project I worked on to get back into coding after being in management for the last few years. It's kind of a cross between popular notepad style calculators (like Soulver, Numi, etc), but also has multi-user editing (like Google Docs). I've got some example templates below which hopefully show what it can do, and hopefully is rel...

Show HN: Confabulists – “Substack for Fiction” https://ift.tt/oDgpver

Show HN: Confabulists – “Substack for Fiction” Hey HN, I am launching a newsletter tool for those who write fiction: https://ift.tt/IhW9k5G This is the page focusing on convincing writers to sign up. It is a two-sided marketplace (writers and readers), but since I am just starting, there are no published writers yet -- who write in English at least. So if you write fiction of any genre, professionally or not, I invite you to try it. Confabulists is the culmination of several personal experiences. First, I am trying to start a new career as a fiction writer. Which is hard. It is one type of content or art creation still heavily controlled by gatekeepers -- book editors. Amazon created a good option for self-publishing, but since it is not "media", it does not offer much opportunity for growing an audience. Or retain it, as there is no guarantee that a reader of one of your books will even know about the release of your latest one. In contrast, creative people that work with vi...

Show HN: iq – jq for images (using rust, LALRPOP) https://ift.tt/q7veQfL

Show HN: iq – jq for images (using rust, LALRPOP) I wanted to share an experimental side project I have been working on for some time. I constantly use commands like `jq` and `yq` for processing structured data in my day job and I was curious if a similar idea could be applied to images. Another goal of mine was to get some exposure to with rust. I discovered the LALRPOP parser generator which really helped moved the project along ( https://ift.tt/2xjyDqQ ) https://ift.tt/ueW7AOd September 18, 2022 at 10:58PM

Show HN: Krita Stable Diffusion Plugin https://ift.tt/BgUutbY

Show HN: Krita Stable Diffusion Plugin This is still a very new project under active development but I wanted to show it off in case anyone is interested in bookmarking it or contributing. Demo here: https://www.youtube.com/watch?v=maWR7dDf4SE Although it will be improving, the codebase has a few issues The Good - ability to multitask within krita while generating images - uses a queue so you can queue up multiple images without waiting for your other batches to come back - no need for a webserver (uses sockets to communicate) - clean code - active development (i want to use this tool myself) - uses stablediffusiond and stablediffusion as separate repos, these can be swapped out as desired with some hacking The Bad - currently relies on rabbitmq and doesn't provide another option - plugin only does txt2txt. img2img works but is disabled - must acquire the model manually The ugly - not all of the features work yet. in fact you can only generate an image. - installation is somewhat i...

Show HN: Course – Testing and Refactoring Legacy Code in Flutter Everyone wants to build cool new shiny features into the app. The truth is, we spend 70-80% of our time maintaining the existing code. It becomes harder when we don't have tests for existing code. In this course, we will learn, How to write tests for existing code in Flutter using different tools and refactoring techniques. At the end of the course, you will be proficient in writing tests for any piece of code and will be confident enough to ship things faster. https://ift.tt/hP3uK7X https://www.youtube.com/watch?v=XHrui_vF2hs&list=PLMURwRbZ0cVJVlMP_GLoNAheU_s7hK8WN September 17, 2022 at 05:06PM

Show HN: A Search Engine for the Tildeverse https://ift.tt/eg2BSDJ

Show HN: A Search Engine for the Tildeverse The tildeverse is the name for a loose community of public access unix systems inspired by Paul Ford's famous tilde.club essay. These little communities are built up around shared access to a single unix system, utilizing its native multi-user properties almost as a retro social network. Over time, the communities have grown and folks published handmade pages that have the vibe of the early WWW days. I built a search engine to let everyone find things on this quirky part of of the net. Enjoy! https://tilde.wtf September 16, 2022 at 06:38PM

Show HN: Aperture Open Source Flow Control and Reliability Platform https://ift.tt/t8eW0C2

Show HN: Aperture Open Source Flow Control and Reliability Platform Hello people of HN and fellow SREs! Over the past year, we have been building Aperture - an open-source flow control and reliability platform for cloud applications. Over the past few years, companies like LinkedIn[1], Google [2], Netflix [3], Stripe [4] have built cutting-edge flow control technologies to keep their applications reliable. Flow control is powerful because it enables graceful degradation- the ability to preserve key user experience pathways, even in the face of application failures. With Aperture project, we hope to democratize building reliable applications with effective flow control. Using Aperture’s powerful policy language, you can deploy flow control techniques such as weighted fair queuing for prioritized load-shedding and distributed rate-limiting for abuse prevention to your applications. Using modular components to build policies allows you to maintain optimal user experience during traffic sp...

Show HN: Cachegrand – a fast OSS Key-Value store built for modern hardware https://ift.tt/se8oNpR

Show HN: Cachegrand – a fast OSS Key-Value store built for modern hardware I am the author of the platform, happy to reply to any question you might have! It scales up really nicely thanks to a year of research and development of the hashtable implemented in cachegrand, on the hardware used for benchmarking, an AMD EPYC 7502P, it was able to reach up to 5mln GET QPS and 4.5mln SET QPS, with batching up to 60mln GET QPS and up to 26MLN SET QPS. cachegrand is fast, it's fully Open Source, it's under a BSD 3-clause license - it can be used easily as standalone platform or incorporated in other ones without any licensing issue - and we are working to expand the Redis functionalities supported and to impelement a tiered storage to cache more data than the available memory. Longer term our goal is to expand the support to different platforms (e.g. memcache, kafka, etc.), add support to webassembly to have user defined functions and server side events, and of course a network bypass (...

Show HN: Rentaflop – Render your Blender projects without sacrificing quality https://ift.tt/G6o75JU

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: StackAid – fund 100s of open source dependencies with one subscription https://ift.tt/ae7AQLC

Show HN: StackAid – fund 100s of open source dependencies with one subscription We strongly believe working on open source software should be a viable source of income for many more developers. Unfortunately, the following barriers limit the extent of open source funding: - Only a small fraction of open source projects are funded, and most money goes to a few notable projects. - Each project has to market is self to get significant funding. - Large corporate donations provide the bulk of the funding, making it unreliable and unattainable for many. - Finding and supporting each of your dependencies is a cumbersome task. Which ones, how much, and on which platforms? So we built StackAid, a service that automatically discovers and funds your direct and indirect (second order) open source dependencies with a monthly subscription. StackAid is early and has a unique allocation model, so we're working with supporters and open source projects to validate the experience further. We're m...

We are in alpha so constructive criticism and feedback are extra welcome! https://ift.tt/8eXtOps September 14, 2022 at 06:33PM

Show HN: ViruSaas – Virus Checks as a Service https://ift.tt/DUBpQLx

Show HN: ViruSaas – Virus Checks as a Service Hi all, here is a side project I've just launched which might come in handy for certain situations. It's a very simple and free "do one thing and do it well" online service with exactly one feature: you upload a file, and it tells you — based on a ClamAV check — if that file contains a virus or not. I'm not having any ambitious plans with this project, but thanks to very low operational costs, I thought I can as well put it out there and keep it alive — maybe it's even useful for some people every now and then (just today, one of my coworkers forwarded me a fishy-looking email with an attachment, and using virusaas.com turned out to be the least painful way to do this kind of one-off check for a virus). I've also released the source code of the web app under GPLv3 at https://ift.tt/NvfYXpG , although it's not as polished as it could be (no tests, for example — but see above, no ambitious plans). The main re...

Show HN: Mini Metroidvania in 13KB of JavaScript https://ift.tt/KAiPM1e

Show HN: Mini Metroidvania in 13KB of JavaScript As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://ift.tt/YRdkzwb NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller ( https://ift.tt/JPetAYD ) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural animation for all characters. - Replacing string enum with numeric enums for compression. - Built a small game engine for object lifecycle and rendering. - Single function to generate unique procedural songs for different regions. https://ift.tt/URwSzJf September 13, 2022 at 11:25PM

Let me know what your thoughts, if you find value in this service or if you have any feature requests. https://ipdetective.io September 13, 2022 at 12:57AM

Show HN: Quake VR – Quake (1996) as a first-class PCVR experience https://ift.tt/HtLf7l4

Show HN: Quake VR – Quake (1996) as a first-class PCVR experience Hello HN! I am proud to show you Quake VR, a "labor of love" one-man project that I started back in 2020 with the goal of turning Quake -- the timeless classic from 1996 -- into a first-class PCVR experience. --- > What do you mean by "first-class"? There are many mods out there that enable older games to be played in VR, however, not much thought is put into VR-unique mechanics or in making the experience feel seamless. While I do enjoy reliving nostalgic classics in VR (and thank the modders for their efforts), it does feel weird having to use a keyboard+mouse setup for a VR game, or -- even with motion controls -- not being able to physically interact with the game's world, or having a gun glued to one of my hands. With Quake VR, I tried my best to make the game feel like an experienced designed from the ground up for VR. A video is worth a thousand words: https://www.youtube.com/watch?v=MBo...

Show HN: We're building a search engine for GCP https://ift.tt/ISeKiV6

Show HN: We're building a search engine for GCP Hi HN, I previously wore SWE/SRE hats on GCP. Later, I was on the other side, managing thousands of machines. The friction points of onboarding and operating cloud systems are personal problems to me. I’ve found it hard to keep track of all the random cloud resources floating around, especially as my team’s assets proliferated. Occasionally, there is a resource affecting an outage but no one remembers where it is. I am constantly frustrated by existing tooling. APIs can work, after you’ve navigated the byzantine documentation, but I often find myself doing ad-hoc tasks which are best served by a UI. Unfortunately, the search bar in the GCP web console does not behave as you expect. For example, it only seems to search for prefixes, rather than substrings, on App Engine stuff. The GCP web console as a whole is boatloads of JavaScripts, 90+ navigation items on the left menu, and a constant stream of UX/UI controls. I'm fond of Hacke...

Show HN: Visualizing Startup Management with Timeline https://ift.tt/SFLUEPg

Show HN: Visualizing Startup Management with Timeline Hi everyone, We are building a web app for startup founders. Like Jira, Notion, or ClickUp, we support task management. However, we think time is more important than the tasks, because startups need to build product fast, and shift focus fast. Therefore, we built one universal timeline to help you easily manage tasks, clients, projects and deadlines, so you can directly compare the important dates from all your departments and find one which matter the most now. We also support task auto scheduling, so when you shift your team to a new direction, you just need to change the priority, and we help you reschedule all the tasks in you team. So you don't need to manually updating the start date or the end date fields in Jira, Notion, or ClickUp. You may have heard of Motion ( https://ift.tt/8Ri4YAb ), which also supports task auto scheduling. Unlike it, our app focuses on serving the startup teams and innovation teams. So we also hav...

Single universal binary, that can be natively executed on every hardware platform Mac OS X was made for (32/64 bit, PowerPC/x86/AppleSilicon). 2. Minimalistic gadget-style design. If launched as a tool, there is no menubar, no dock icon, no nothing, just the clock window. 3. Support for hidpi and dark mode for environments, that have them. 4. Window title bar for moving the window with a mouse, and a handle to resize it (latter for OS versions, that have it). 5. Can be easily ported to GNUStep and thus other OSes (sources under GPLv3). 6. Simple Makefile build system. https://ift.tt/kwe1Zlf September 7, 2022 at 10:25PM

Of all the available resources out there, I wanted to have a place where I could practice coding questions myself (and to mimic a coding interview setup) and solve the problems with a time based approach. After 2 months of questions curation, I've come up with the first set of questions that are being asked in Big product based companies that assess candidates on their React skills. Use Algochurn to speed up your interview preparation. Save and Bookmark questions, Mark question as completed and use a time bound approach to solve problems.

Show HN: I made Scrabble with modified rules https://ift.tt/b18NHms

Show HN: I made Scrabble with modified rules Crapple is my take on "improved" Scrabble rules... obviously that is subjective, I'm not even sure I agree with it. You and your opponent share a rack of letters, and vowels are only obtained by opting to deduct a configurable amount of points from your score to receive a random vowel tile. Additionally, there is an alternate board layout with some new tile multipliers. This is an old project but I never posted it, so I thought what the hey, I am curious to hear what your guys' thoughts are on these rules. It's an old dead project so you can't hurt my feelings. Thanks! You can play it now against the computer in your browser (no signup required, but an account lets you create and play games against other humans). The Android app is the better version only because the AI will run on a seperate thread (in the browser version you might see a hiccup while it runs), and because Unity WebGL doesn't export retina-sized...

Show HN: Alumina Programming Language https://ift.tt/Mi4QIfH

Show HN: Alumina Programming Language Alumina is a programming language I have been working on for a while. Alumina may be for you if you like the control that C gives you but miss goodies from higher level programming languages. It is mostly for fun and exercise in language design, I don't have any grand aspirations for it. It is however, by this time, a usable general-purpose language. Alumina borrows (zing) heavily from Rust, except for its raison d'être (memory safety). Syntax is a blatant rip-off of Rust, but so is the standard library scope and structure. Alumina bootstrap compiler currently compiles to ugly C, but a self-hosted compiler is early stages that will target LLVM as backend. If that sounds interesting, give it a try.

Show HN: I made an indie app store alternative with a twist The twist is that although it does (part of) the job of an app store, it's not (nor aims to be) an app store. It's a script you add to your existing web app that makes it "self-distributing". Check it out: https://progressier.com. Under the hood, it leverages the concept of "PWA", but it goes further: 1. It creates an installation page for your app that looks like an app store listing. Demo example: https://ift.tt/VN0nwY3 2. It handles every OS/browser combination to create an installation flow that works everywhere (e.g. on Safari/iOS, with in-app browsers, etc) 3. It lets you manage all the technical aspects of your PWA in a dashboard rather than in code (i.e. service worker, app manifest, caching strategies, icons, etc). You can even send push notifications and design app screenshots from Progressier. Caveats: - It only works for web apps - It's not free! - An app store is supposed to handle ...

Show HN: Pith language. JavaScript with a little bit of Python syntax https://ift.tt/gCF3U6u

Show HN: Pith language. JavaScript with a little bit of Python syntax I've been writing a lot of JavaScript and Python lately. I like Python's syntax, so I created a language called Pith that's JS with some Python-like syntax (but without trailing colons). It's not a full compiler. It really just does search-and-replace, but I find it fun and useful in spite of some sharp edges. I use it on my smartphone to write and run short programs. Here's an example using the HN API: max = 6 ids = await getApi('topstories') for id in ids.slice(0, max) getItem(id) async def getItem(id) const d = document.createElement('div') results.appendChild(d) d.style = 'padding-bottom: 1em;' i = await getApi('item/' + id) ? i.title, '|', i.score u = '//news.ycombinator.com/item?id=' d.innerHTML = i.title.link(u + id) async def getApi(path) u = '//hacker-news.firebaseio.com/v0/' return getJson(u + path + '.json') https://ift.tt/...
