Show HN: AirQL: An Airtable API with OAuth2 access control and permissions https://ift.tt/X9aAcbJ

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 us know what you think! We’re looking for feedback and to learn if this would be useful to others. If you have questions or suggestions, please get in touch at airql-support@bitcomplete.io.

Show HN: Red Goose – Convert your website to mobile app https://ift.tt/Lp9RXgW

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 genuinely caught on. It has matured to a point where the four pillars of web development—HTML, CSS, JavaScript, and WebAssembly—are likely enough for universal distribution. We already host compute-heavy environments for graphic designers [4], video editors [5], and rich document editing [6] on the web. And there is still more capability [7] in the works, if you will. So the question we asked ourselves was: Could the modern web become the "native stack" of mobile app development? With Red Goose, we want developers to be able to do just that. Create web applications that double up as mobile apps for the app stores. But this isn't always easy. Historically, native mobile apps have differed from (outdone?) the mobile web in three broad ways: An app-specific design language, Smooth and fancy screen transitions and, Solving compute-heavy processes that scaled to millions of users. However, at the same time, building and maintaining native mobile apps is super expensive, and it requires hiring separate teams of experienced developers whose sole job is to focus on mobile APIs. Even with the newest alternatives like React Native, Flutter, Cordova, Xamarin, Ionic, or any other similar framework, there is a quantum increase in the amount of boilerplate code. Over time, as many of us have experienced in the industry, the web and native teams grow distant, leading to a less than optimum situation and bloat. Red Goose puts the webview back in the ring. This step alone removes all the duplicated code from the equation. Red Goose then offers an alternate strategy [8], using the webview as the main leverage over your web app. And solve for native experience in the following three ways: First—Intrinsic Design: we have built a new css framework called Toucaan [9] to tackle the gaps between mobile app design and mobile web. It allows the development of "app-like" interfaces using new css standards and the intrinsic qualities of the medium. Second—Screen Transitions and Animations: Not all apps need this, but smooth transitions and performant animations are already possible with the new web APIs. With a strongly cached webpage using a service worker (PWA) and a better understanding of initial containing blocks (ICBs) pertaining to your front end, one can easily take steps to take the experience to the next level. Third—Webassembly: The best thing about webassembly is that the wasm functions return immediately and synchronously. So one can easily offload compute-heavy transactions to a locally installed wasm utility and benefit from performance gains instantly on both web and mobile apps. It appears that many apps wouldn't need to sprinkle webassembly into the mix to reach the level of performance expected of mobile apps, and just caching with a service worker and an app-like layout would do the trick. Red Goose itself uses vanilla javascript and an experimental version of Toucaan for its frontend. Its backend is made with Node.js, Express, and MongoDB and is hosted on AWS within Docker. Our web-to-mobile app conversion pipeline uses NodeGit for app delivery, and the freshly minted mobile apps are written in Swift or Kotlin and shared directly over GitHub. We believe that the opportunity to reduce app development and distribution cost using the newfangled powers of the web is massive—we've already helped a few teams to cut back on their expenses by as much as 80%. At the same time, we're still early and would love to hear what you think about what we're building with Red Goose. We look forward to your comments and experiences, especially if you have been on this path before on your own. Thanks!

Show HN: Restapp.io – SQL Data Modeling Tool in No/Low Code https://ift.tt/jzXa5S2

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 and pipelines to specific users (colleagues, partners, clients...) We've designed this because as a data team member, we were writing a lot of long SQL queries with bad performances and we were getting headaches by debugging them. Now you can build, monitor and debug any kind of data pipelines with just Drag-and-drop built-in SQL functions to save you tremendous amount of time & effort. We're working on this continuously so we're keen to hear any feedback. Feature requests and critique are more than welcome. Try it out for free (30min of computing time offered each month): https://ift.tt/Bw1gfuq The Getting Started docs are here for anyone who wants to check this out: https://ift.tt/h6Brxlu and https://ift.tt/TY58E9n... https://ift.tt/Bw1gfuq September 28, 2022 at 12:14AM

Show HN: I wrote a database engine in TypeScript https://ift.tt/jfC5PIH

Show HN: I wrote a database engine in TypeScript Hi! I wanted to understand more about databases' internals so I wrote one from scratch. It has a T-SQL inspired syntax with support for functions and procedures. It can be used stand-alone as a SQL engine or with a server allowing for persistence and replication to other connected clients. Performance are nothing near sqlite of course but that's beside the point. It’s a small database engine that can run in a web app as a way to store session data, do small calculations on a web worker, store the document/data the user is editing or facilitate “multiplayer” feature by broadcasting the queries the web app is running. The server runs in a container for that specific document and shutdowns automatically after a set amount of minutes of inactivity. Why did I spend time on this? I am self taught and have been a software developer for about 20 years; moved to the UK for about 10 years, now in Spain and I'm still looking for the place I want to call home. My lack of diploma has never been an issue in Europe but if I want to discover other horizons, having one makes things easier. There's a process in France call "Validation des acquis" (Validation of knowledge) which allows anybody at whatever level to present to a panel of professionals and academics a request to validate one experience and deliver a diploma. That diploma is completely equivalent to a diploma delivered from a university. The experience must validate all of the targeted diploma curriculum so I thought digging into databases will help with that... Any questions, hate mail can be directed at alex at ixai.net. I'm also looking for a remote position as a Senior software developer https://ift.tt/GolFXLV September 28, 2022 at 06:53AM

Show HN: Media Hoarder – media front end for data hoarders and movie lovers Here's a video showcasing Media Hoarder's features: https://www.youtube.com/watch?v=TGkU9e1l8HU As we're on hackernews I wouldn't go much into the features of Media Hoarder with this post (see the video above for that). I'd rather like to comment on the DX. I'm a long-time lurker here on HN and in 2019 I felt the urge to develop my own take on a media center application. Media Hoarder was already usable after a few days of development and after one year it had 90% of the features I wished for myself but was not exactly ready for a release to the public. So, for this project the last 10% took another two years :) During the development I read a lot about the "ship fast" mindset which I obviously did not adopt. I could never live with a publicly released version that does not completely show what I had in mind with the app. And yeah, currently my focus is not to get external feedback as fast as possible but to create and release a product as v1.0.0 that I envisioned and use myself. The tech-stack is: - Electron - Vue.js with Vuetify - SQLite this way the app runs on Win/Linux/Mac and can be entirely developed with web technologies - which to me is a great plus regarding development speed. Mind you, Media Hoarder is developed during the free-time of a father of two young kids :D Anyways, I'm really glad it's out there. Personally, I use it every day and I hope, some of you may find it useful or would like to contribute. Please feel free to discuss features, development and sideproject-y things, I'm really curious :) Media Hoarder Website: https://ift.tt/5emRBkY Blog post "Why Media Hoarder?": https://ift.tt/Fg9CcTx GitHub project: https://ift.tt/w4i7n86 cheers -- MK2k https://ift.tt/5emRBkY September 23, 2022 at 04:20AM

Show HN: The simplest drum pattern composing algorithm I could come up with https://ift.tt/W2EJsSY

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/zdung0m). 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 think I figured out why. Most of the new users are getting frustrated because it is very easy to get stuck trying to come up with a fresh drum pattern, and so https://twitter.com/DrummyBot was born! A function written in less than an hour that comes up with pretty decent rhythms. While not in any specific style, and no ability to choose settings or tune it, it may still be a great kickstarter for that new beat you just can't seem to find. It is like the opposite of a fancy AI that seems to be so hot these days. If you think DrummyBot can help you get inspired, just follow it on Twitter. The bot publishes a new pattern every hour, and even tries to give it a name using PHP's Faker library. You can also simply go to https://drummy.io and use the magic wand button to get a fresh pattern with each click! The function is totally randomized, you will never get the same pattern twice, and customizing literally requires just a few seconds. I hope you like it, and of course, all feedback is gladly welcome! September 21, 2022 at 02:33AM

Show HN: Search for the Best of Anything https://ift.tt/rj7hbJP

Show HN: VoiceLine – Work with STT voice messages in your Chrome Browser Hey all, I’m super happy to share the official launch of the VoiceLine Chrome Extension that my colleagues and I have been building over the last year. It allows you to record, share, and play voice notes within any browser-based application. We’re using an STT model to transcribe your notes into what we call a VoiceLine, a hybrid audio-text snippet, to address the problems of conventional voice messaging. Our vision is to introduce a new category of professional voice communication by building our service as a layer, not yet another instant messenger like Slack or MS teams. It works within any tool like Jira, GitHub, G Suite, Notion, … you name it. Would love to get some feedback and support, we’re also on producthunt today: https://ift.tt/Lk2xvUI https://ift.tt/NC5RjIZ September 20, 2022 at 04:00AM

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

Show HN: Confabulists – “Substack for Fiction” Hey HN, I am launching a newsletter tool for those who write fiction: https://ift.tt/Vx1D5c8 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 visual arts have TikTok, Instagram, YouTube, Vimeo, Twitch. Audio creators have the video platforms as well, but also Spotify, Deezer, Bandcamp. And finally, creators of the written word benefited from the resurgence of newsletters. Substack took it to a new level, attracting great thinkers and journalists with a good model for these professionals to earn their money a bit more directly. I am a big fan of Substack. I created my newsletter there early on and tried three times to get a job there as a software developer (always politely rejected because they don't hire globally remote). But, despite a few recent efforts, I don't think Substack is a good place for fiction writers. The main thing is that writing fiction takes time. It's hard to post new fiction weekly. And fiction is about past, completed works. Something that the current media landscape, newsletter tools included, strongly incentive against. You should always be creating new content. A new subscriber only gets your future work. Past texts are for those with a neck for digital archeology. That's why I created Confabulists. The main difference in the tool is that new readers, when they subscribe to an author, choose a book and start getting that book in installments from the first chapter. Completed books matter. "Old" fiction attracts new readers. Another experience that led me to Confabulists was a free site that I built and launched in a Show HN [0] a couple of years ago: https://ift.tt/zvBgICo It was built for reading of public-domain classics in installments delivered by email. Just like Confabulists is for new authors. It got some traction here on HN and proved to me that people really engage in reading fiction in their email inboxes. At this peak, right after the Show HN, it had 800 active subscribers receiving installments from a book. Today, after two years, with zero marketing effort (I never even posted again on social media or anywhere), there are almost 200 active subscribers. No available book lasts that long in weekly installments, so these are either people who subscribed to a new book or new subscribers that found Serial Literature through word of mouth. For a zero-marketing effort, I consider this good retention and evidence that reading fiction through email has its audience. I am solo on this. From idea to coding, to copy and design -- this last one with AI help with the illustrations. As a Brazilian and wanting to publish my work on it, I created it initially in Portuguese [1]. It was great for the beta reading of my first novel. And useful to find and fix some bugs and iterate the product until I had a solid solution. I think it is good enough to try to reach more people with its version in English. I hope some fiction writers on HN find it useful too. Thanks!

Show HN: WalletWatch – a social network for Ethereum wallets https://ift.tt/2OfylEP

Show HN: WalletWatch – a social network for Ethereum wallets Hey HN, I’m Kamil and one of the two people working on WalletWatch. We recently graduated college and have been getting more into crypto / web3 over the past year. A few of our friends had been getting into crypto more recently, but we noticed that it was hard to actually see what they were doing or natively engage with the transactions they were committing. Products like blockchain.com and etherscan.com were too technical, and products like Context or Zerion lacked key features that make modern products social, such as descriptions, likes, and comments. We built WalletWatch as an easier, more social, and more fun way to see and engage with your friends’ Ethereum activity. We don’t ask for your email or password, and instead authenticate by asking users to sign a transaction with their Ethereum wallet; we ask for usernames to give a more familiar and user-friendly experience for people that haven’t purchased ENS or other crypto domain names. At the moment, we’re storing user data in Firebase instead of on-chain because the current decentralized channels are too expensive or slow. We consider WalletWatch as pre-alpha. The website only renders in a mobile viewport and isn’t totally visually or computationally optimized, because we wanted to see if people liked this thing enough for us to spend more time making it polished. We’d love any feedback you all have! https://ift.tt/dYfw5PG September 17, 2022 at 08:35AM

Show HN: Off-site, encrypted backups for $1/TB/month at 99.999999999% durability Hi, most people (hopefully) have local backups. However, when that backup fails, it is good to have a backup stored somewhere off-site. In the old days you would ship physical drives/tapes, which is cumbersome, costly, and slow. With fast upload speeds, it is now possible to upload your data to the cloud. I have found S3 Glacier Deep Archive to be a great solution for this: - It is very cheap ($1/TB/month for US region) - Very reliable (99.999999999% data durability, data spread over 3 Availability Zones) However, usability out of the box is not that great, I'm not aware of any automated backup solution for Deep Archive. This free project provides that. Currently, ZFS is required, but that might change. Please try it out and provide feedback! https://ift.tt/4nw6z7H September 15, 2022 at 11:33PM

Show HN: Aperture Open Source Flow Control and Reliability Platform https://ift.tt/8QjvPJ3

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 spikes, prevents cloud resource wastage by regulating abusive users, and ensures that new feature rollouts don’t result in accidental downtime. We are excited to release Aperture as an open source project under the AGPL v3 license and invite SREs, DevOps, enthusiasts to give the project a try. We would love to hear your feedback on Aperture and how we can improve! Github: https://ift.tt/m0rUAgG Docs: https://ift.tt/O8SfTxr Announcement: https://ift.tt/i2QzgjC...

Show HN: Rentaflop – Render your Blender projects without sacrificing quality https://ift.tt/69p3um4

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 public beta. If you'd like to try us, check out our site (https://rentaflop.com) and render your Blender project quickly and affordably! 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. We posted about our private beta on HN a few weeks ago. If you'd like, you can check out the discussion here (https://ift.tt/23K4mhN). Please leave a comment below, we'd love to hear your thoughts :) September 14, 2022 at 05:34AM

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 matching subscriptions up to $100/month during the beta. https://www.stackaid.us September 14, 2022 at 04:35AM

Show HN: ViruSaas – Virus Checks as a Service https://ift.tt/0aVbwT6

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/yDcgWqP , although it's not as polished as it could be (no tests, for example — but see above, no ambitious plans). The main reason to do the project was to follow through with my own tutorial at https://ift.tt/3ZxbuYP... , which worked out quite nicely. https://ift.tt/RtmE8Vp September 14, 2022 at 01:19AM

Show HN: Quake VR – Quake (1996) as a first-class PCVR experience https://ift.tt/F8JRqdB

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=MBoI16z8Nxg --- As you can see from the video above, Quake VR provides a plethora of VR-specific features, including: - Virtual in-game hands with finger tracking - Dual-wield weapons or hold a weapon with two hands - Physical melee combat, including throwing weapons and headbutts - Weapon models with ironsights - Collisions between the player's hands and the environment - Holster system with virtual torso For a complete list of features, check out the README: https://ift.tt/Bgl2i7b I love VR-unique interactions, and I try to find opportunities to add more. As an example, I recently added "flick reloading" to the SSG -- see it in action here: https://www.youtube.com/watch?v=uV8gbDvNYAM . Here is an older trailer showcasing features like dual-wielding, holsters, and the grappling hook: https://www.youtube.com/watch?v=c_ctxSqs6gA --- Quake VR is written in modern C++ and it's completely free and open-source : https://ift.tt/uynk9GR . If you have any question about the game or any implementation detail, feel free to ask here on or the official Discord server ( https://ift.tt/e8DNKOa ). --- If you have a PCVR headset, I sincerely hope you will check out the game and let me know what you think! The game is available on a "pay what you wish" model here: https://quakepcvr.com/ - Make sure you closely follow the installation guide ( https://ift.tt/8sCr1hL )! Cheers, Vittorio --- FAQ: > Is this project related to the Quake ports available for the Meta Quest? * No, this project is separate from those. It uses a different engine and it was developed by me, Vittorio Romeo, with some very appreciated contributions by community members (https://ift.tt/AkgbmfH). > Why is Quake VR not available on Steam? * I've tried really, *really* hard to release it on Steam as a free community mod. However, that requires permission from the owners of the Quake IP. I have spent countless hours trying to communicate with id Software, Bethesda, Microsoft, never receiving *any* sort of response. I've even tried directly contacting employees, who kindly forwarded my request to the legal team, to no avail: zero answers whatsoever. I have not given up -- if you know someone that can help, please let me know! > Is Quake VR compatible with existing Quake mods or existing Quake servers? * No, Quake VR uses a custom protocol and engine in order to deliver first-class VR features. It is possible to adapt mods to work with Quake VR -- I have done that for the official expansions and some popular mods. > How can I support the Quake VR project? * Quake VR is FOSS, however I am more than happy to accept donations for my efforts. PayPal (https://ift.tt/bREwU9p) works best for me, alternatively consider purchasing "Open Hexagon" (https://ift.tt/RVUq04d), my first commercial game on Steam. https://ift.tt/xfQv5JS September 10, 2022 at 06:27PM

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

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 HackerNews and Craigslists, because ultimately, we just need to list/search and maybe submit a webform. This year I convinced my friend to quit their coding gig on Wall Street to help me make the cloud accessible. We’ve started with a small tool to this end: a search engine for the cloud. What we have demo-able for you today is the GCP component of it. Our tech: - Go with conservative sprinkles of VanillaJS. It allowed us to focus on the domain rather than the language. - SSR. Right now the pages are under the magical 14kb, but we’re eyeing the - HTMX (rendering fragments of HTML strings from the server) pattern - We’ll dabble with Elixir, Rust, and Zig in other parts of the system - GCP (We think GCP runs great once you get set. The problem is getting to that point, which is what we want to help others do). We also have some stuff on AWS. - Plaintext. Our “agile process” was a TODO.org file, and Git. It’ll be super fun to do a timelapse of it. https://ift.tt/eojEgzb September 9, 2022 at 06:57AM

Investors earn the booking income & property appreciation from being an owner, without all of the work typically involved. Airbnb’s can be a killer business. They have helped vacation rental owners generate over $150 Billion in rental income from serving a billion guest arrivals, but less than 0.5% of these guests have been able to participate in the owner side of the Airbnb economy. Arrived is the first company with SEC Qualified offerings to buy shares in individual properties like this.

Show HN: VoxelChain – An Experimental Voxel Engine VoxelChain is an experimental tool to create voxel worlds in the browser. The lighting is fully ray traced in real-time and there is powerful cellular-automata based programming system, which allows to create complex digital circuits and model the behaviour of voxels (behaviour such as falling sand or water). Technology wise, I'm using WebGL2 for the rendering and the simulation is coded in C89 and gets compiled to WebAssembly (with multi-threading) using Clang. The simulation is basically a custom cellular automaton and is fully parallelized. Once WebGPU is released, I'm planning to run the simulation on the GPU, instead of the CPU, which will give a massive speed up. I've been working on this project full-time for over a year now, and finally came to the point of realising a public version of it to play with. There is already some really cool stuff that the community has built, and it's super fun to see how everything evolves!

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

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 graphics (ie graphics may look less than sharp on your mobile device). (Note: I linked the landing page instead of the direct link to play in case you are on mobile and want to avoid a largish download. Direct link to play in the browser is here: https://ift.tt/qgmHdZ7 ) --- Some more details for anyone still reading... It's your basic LAMP stack on AWS, with Laravel for the web framework and Unity (2017) for the client. The dictionary is stored as a DAWG. When you play a word, instead of giving you the dictionary definition, I wanted to do something different like provide a paragraph from a book that the word was used in. You can click the book icon to get some of those, I was scraping books in the public domain but gave up after a while when I was getting diminishing returns for words I lacked paragraphs for (if you try it you will likely see a lot of Moby Dick paragraphs as I never randomized it either). The AI was based on the scrabble AI algorithm (I think it was this, but can't remember now, https://ift.tt/cZD3qLF... ). Since Crapple has modified rules, due the possibility of "buying" vowels on your turn, there is set of _potential_ playable words. The Crapple AI ranks each word based on the cost of the vowels needed with their probability of obtaining the needed vowels. The AI is not very intelligent, the difference between the 3 provided computer opponents is just the average word score they will play. If I had worked on this any longer I could have extended this to let them take into account what words/scores they may be setting you up for with their play, and other ideas. Each player's avatar is consistent, but uniquely generated for them. I didn't want to have every using the same boring default avatar, but didn't want the hassles of letting people upload their own, so I went with a version of this idea: https://ift.tt/BO2Xy9t https://crapple.mobi/ September 3, 2022 at 10:15AM

Show HN: Alumina Programming Language https://ift.tt/cqEx2gh

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. I appreciate any feedback! Standard library documentation: https://ift.tt/Y2JWkAE Online compiler playground: https://ift.tt/MJ6Z8xi https://ift.tt/OTmiAkd September 3, 2022 at 05:32AM

Show HN: I'm building an open-source Amazon https://ift.tt/VsI2CBE

Show HN: I'm building an open-source Amazon A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing marketplace. In 2019, I started building the first piece, Openship, an order management system that lets you source orders and fulfill them from anywhere. Now that that’s in stable release, next up is Openfront (an e-commerce platform for storefronts) and Opensupport (ticketing software for customer support). Together, they provide the staples for any modern business: sales, fulfillment, support. Let me know what you guys think of the idea and if you see any potential pitfalls. https://openship.org/ September 2, 2022 at 03:19AM

Show HN: Pith language. JavaScript with a little bit of Python syntax https://ift.tt/TRCf8i0

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/nqkLP2d September 1, 2022 at 08:47AM

Show HN: Open-source infra for building embedded data pipelines https://ift.tt/C1lw7s0

Show HN: Open-source infra for building embedded data pipelines Hey HN! We are building *open source infrastructure for deploying customer-facing data pipelines.* Here’s our repo https://ift.tt/CIGe2L0 and website https://pipebird.com/ . Pipebird is designed to enable companies that generate important data to offer secure data pushes to their customers’ warehouses, directly from their products. Our team was previously building in fintech, where we heard from many of our peers that their customers wanted data pushed directly to their warehouses. Customers wanted to bring data into their source of truth without having to maintain custom built pipelines or introduce security risks by contracting a third-party ETL/ELT provider. After seeing Stripe https://ift.tt/R82czo5 and customer.io https://ift.tt/mVkbsRj recently invest in building out their own native data sharing products, we realized that many SaaS companies could better support their customers and even generate additional revenue by offering native data pipelines. Our goal with Pipebird is to make creating a reliable data pipeline as simple as pressing a button from a vendor's dashboard. With the current iteration of the product, data can be selected from a number of sources (ex: Postgres, MySQL, CockroachDB, etc.), customers can configure pipelines and optionally apply transformations (like type casting), and data can be periodically synced directly to customers’ warehouses (ex: Snowflake). We’re actively adding sources/destinations and would appreciate any feature requests. Here's a 2 min demo of the product https://ift.tt/60h3LGu Pipebird is open source (MIT license) so that any developer can use it. Our aim is to not charge individual developers - we make money selling paid plans that include features like multiple projects, user permissions, additional security features, managed infra, support, etc. Give us a whirl: https://ift.tt/CIGe2L0 . We’d love your feedback and will be here to answer any questions! https://ift.tt/CIGe2L0 September 1, 2022 at 06:57AM
