Show HN: Klipit.in – Online clipboard, quickly share data across devices Hello, wanted to share about my new project called Klipit. How do you quickly share data between devices? Here's what most people do – - Send it to someone on WhatsApp or other messaging service. - Email it to themselves. - Use a note taking application like Google Keep, Apple Notes or OneNote (my preferred way until now). All of these require you to already have those services logged into on both the devices. Logging into any service on a new device these days is a tedious process involving 2-factor authentication. What if there was a quick way to share data between devices? One that did not require any logins or installing any apps? Starting with this thought, I built Klipit.in. An online clipboard to share data quickly between devices. You get an instant online clipboard with a unique link. No need to create any account. You can paste any data to this clipboard and simply open the link on another device. Nothing to install, no logins required. Quick and easy. There is also a QR code which you can scan to open the clipboard in browser. Some features that I may add depending on how it takes off - - Password protection - Real time refresh - Sharing files - Klipit account with multiple clipboards - Custom clipboard URL Play with it and let me know what you think. https://ift.tt/JYnGL9i October 25, 2022 at 06:23PM

Show HN: Podcastsaver.com – a search engine testbench dressed as a podcast site Hey HN, I submitted PodcastSaver (https://ift.tt/veTi8IG) before but the reason it's interesting now is that I've started converting it into a live search engine test-bench. I've discussed it a bit here[0], and this idea has been kicking around in my head for a while so I got a chance to do some related writing about it with Supabase[1]. The basic idea is to use a modest piece of the podcast index[2] as a place to test out different new age search engines against each other. So far there are two engines running: - Postgres FTS + pg_trgm (tuned -- indices are there, I did some EXPLAINing earlier today to tighten things up, but still all built-in tech) - Meilisearch (untuned -- just stand it up, give it resources and put in documents) To that effect, I've added a "nerds" page you should peruse: https://ift.tt/l0GUyE9 On that page you can: - choose your search engine - choose whether to force disable the cache (obviously... you'd want that, for the results to mean anything, but for regular people surfing the cache is on!) As far as actually getting the podcast search really good, there is a ton of curation left to do so it's a subpar consumer product still, but it's interesting from at least this angle! Going to add more search engines later but who knows when (this project was supposed to be short!). I can't add every engine on the huge list of new-age search engines[3], but I can say that I will get to highlighting all of them in Awesome F/OSS[4]... Eventually.

Show HN: Contact Form Delivery Most sites I work on have at least one contact form and I got tired of building out the logic to send them and handle the spam into every project. I built and launched Sendfly for myself 5 years ago and it's been a rock solid service that I've relied on ever since. Recently I've done a full re-write, simplifying the product and making it super affordable. I wanted to share it here in case it comes in handy for someone else. There are lots of competitors out there but I found them too expensive for my needs. For $15/year you get unlimited forms and 5,000 form submissions every year. Hoping that fits the bill for developers like me! https://sendfly.io October 23, 2022 at 01:16AM
Show HN: C Injection Compiler – Program your text files in C It's very early in development but it has just reached a working state so I'm actually using it now to generate content for my website.

Show HN: SoundSeeker – Organize Your Musical Ideas Hi HN, I've been programming for about three years, and this is my first full-stack web app. It's a tool for organizing musical ideas. Building and deploying it has been a great learning experience, and in that spirit I'd be grateful any thoughts or suggestions if you care to take a look. Thank you! source: https://bit.ly/3giqrBU Why: Composing music is different for everyone, yet some practices are employed by many musicians. One such practice is to record a musical idea on a phone, capturing the idea at its freshest, and for many, clearest. This often leads to a lengthy catalogue of chronologically organized recordings that can be difficult to parse when sitting down to flesh out a piece of music – what matters most is the content of the idea, more so than when it was conceived. The purpose of SoundSeeker is to allow you to organize musical ideas based on their content instead of when they came to be, and to serve as an educational personal project in my growth as a software engineer. What: A graph-based organizational tool for scratch audio recordings Planned features: in-app audio recording, in-app editing, custom labeling outside of the main tiered organizational system. https://ift.tt/k7FhmJH October 20, 2022 at 05:45AM

Show HN: HacKit, a macOS app for reading Hacker News stories and polls I wrote a macOS app for reading Hacker News stories and polls and recently released version 3.0 with new features. It is written in Swift and uses AppKit framework. It is a Mac-first app which is built for the macOS design language. It looks and feels and works like a proper macOS app made with love and care. It is not a port of an iOS nor an iPadOS app nor anything else. I am quite proud of it and I hope you can appreciate it too. So, I recently updated it to version 3.0 with new features such as tracking stories by marking it as (un)read, (un)favourite and (un)hidden. There is also folder management to organise stories and smart folders that track stories by certain attributes. It also supports the Touch Bar with customisations. I would love it, if you could try it out and let me know what you think of it! I welcome feedback and please do let me know if there are any bugs or crashes. I did all the testing myself to the best of my ability. Oh and about the in-app purchases, it is just the tip jar and it is completely optional. The app and all its features are absolutely free to use. If you like HacKit, please kindly leave feedback on the App Store. It really helps, no really! Have a good week! https://ift.tt/DjPxKrA October 19, 2022 at 03:55AM
Show HN: Linen – open-source Slack for communities Hi HN, My name is Kam. I'm the founder of Linen.dev. Linen communities is a Slack/Discord alternative that is Google-searchable and customer-support friendly. Today we are open-sourcing Linen and launching Linen communities. You can now create a community on Linen.dev without syncing it from Slack and Discord! I initially launched Linen as a tool to sync Slack and Discord conversations to a search engine-friendly website. As I talked to more community managers, I quickly realized that Slack and Discord communities don't scale well and that there needs to be a better tool, especially for open-source knowledge-based communities. Traditionally these communities have lived on forums that solved many of these problems. However, from talking to communities, I found most of them preferred chat because it feels more friendly and modern. We want to bring back a bunch of the advantages of forums while maintaining the look and feel of a chat-based community. Slack and Discord are closed apps that are not indexable by the internet, so a lot of content gets lost. Traditional chat apps are not search engine friendly because most search engines have difficulty crawling JS-heavy sites. We built Linen to be search engine friendly, and our communities have over 30,000 pages/threads indexed by google. Our communities that have synced their Slack and Discord conversations under their domain have additional 40,000 pages indexed. We accomplish this by conditionally server rendering pages based on whether or not the browser client is a crawler bot. This way, we can bring dynamic features and a real-time feel to Linen and support search engines. Most communities become a support channel, and managing this many conversations is not what these tools are designed for. I've seen community admins hack together their own syncs and internal devices to work to stay on top of the conversations. This is why we created a feed view, a single view for all the threads in all the channels you care about. We added an open and closed state to every thread so you can track them similarly to GitHub issues or a ticketing system. This way, you and your team won't miss messages and let them drop. We also allow you to filter conversations you are @mentioned as a way of assigning tickets. I think this is a good starting point, but there is a lot more we can improve on. How chat is designed today is inherently interrupt-driven and disrupts your team's flow state. Most of the time, when I am @mentioning a team member, I actually don't need them to respond immediately. But I do want to make sure that they do eventually see it. This is why we want to redesign how the notification system works. We are repurposing @mentions to show up in your feed and your conversation sections and adding a !mention. A @mention will appear in your feed but doesn't send any push notifications, whereas a !mention will send a notification for when things need a real-time synchronous conversation. This lets you separate casual conversations from urgent conversations. When everything is urgent, nothing is. (credit: Incredibles) This, along with the feed, you can get a very forum-like experience to browse the conversations. Linen is free with unlimited history for public communities under https://ift.tt/pJbRFV7 domain. We monetize by offering a paid version based on communities that want to host Linen under their subdomain and get the SEO benefits without managing their own self-hosted instance. We are a small team of 3, and this is the first iteration, so we apologize for any missing features or bugs. There are many things we want to improve in terms of UX. In the near term, we want to improve search and add more deep integrations, DMs, and private channels. We would appreciate any feedback, and if you are curious about what the experience looks like, you can join us here at Linen.dev/s/linen https://ift.tt/jvoAbXe October 18, 2022 at 08:42PM
Show HN: Xzgrep is twice as fast with dash versus bash In the CentOS world, a shell script written by "Charles Levert" has been extended as the compressed grep for (gzip/bzip2/xz) as /bin/(zgrep/bzgrep/xzgrep); variants of this script are bundled in their respective packages. The dash shell, available in EPEL for CentOS, appears to specifically speed up xzgrep considerably when altered from #!/bin/sh to #!/bin/dash. In my testing on a 32-bit platform under xargs, a search of 14k files of 20M total size runs in half the time. Do others see this performance increase? Is this another tangible benefit for Debian/Ubuntu moving the system shell from bash to their Almquist shell derivative? October 17, 2022 at 11:42PM
Show HN: Play against well-known chess players' openings Hi, this is my first HN submission so please forgive the rough edges. For this project gathered chess positions from some well-known chess players with a lot of games. (Usually ~25k games and 1M+ positions. The most for any player was GM Aman Hambleton with 1.8M positions indexed.) With each board position I create a probability distribution of moves the player has made from that position. Then, I simply draw from that distribution (with sampling temperature) to choose a move. As long as there's at least one game with a given position, you can keep playing. You'll see that it's pretty easy to get "out of book", where you've reached a novel position. It is possible to indirectly model a player's behavior throughout the game, so we can guess what moves a player might make in that position. But that's a bit more than a weekend project and a bit more involved than a lookup table. https://ift.tt/G7KAnZ6 October 17, 2022 at 08:47AM
Show HN: ESInfer – Make JavaScript Type-Safe Hello, folks. I'm Jiang, the author of ESInfer. I love writing Javascript because it has a prosperous ecosystem and is quick to get my hands dirty. However, sometimes it's painful when the flow is not fast to follow due to the lack of a type system. To solve this, I wrote ESInfer, a statical inference tool, to automatically type check and generate type annotations for Javascript. It works with pure Javascript without any add-ons to the language or user-space code and supports highly dynamic features, such as the modification of prototypes. It is still in the very early stage, which offers almost all ES5 features and a select set of ES6 features like array/object destructing. I'm working hard to bring all ES6+ features into it incrementally. If you heavily use javascript/typescript and do NOT want to write the type annotation sh*ts anymore, give it a try :) https://esinfer.com/ October 15, 2022 at 05:33PM

Show HN: Simplepdf.eu – a browser-based PDF annotator / editor Hi HN! I've been working on SimplePDF to solve a problem I encounter weekly: filling out non-editable PDFs [1] --- # About SimplePDF - The documents you load, edit, fill never see the light of my server, everything is processed locally – no remote uploading anything. This includes the PDF generation. - There are no analytics / third party tracking your every move (I do collect usage data, but it's fully anonymous and processed and stored on my server): therefore no annoying cookie banner. You can read more on the Privacy Policy [2] - If someone before you has filled the same document, upon opening it you'll see fields already set, ready to be filled-in, think crowd-sourced fields positioning – saving you time and effort. --- # How does the crowd-sourced positioning of fields work? When a document is loaded in your browser, a fingerprint of the document binary is made, and sent to the server. The document table consists of: document_id, fingerprint and created_at. As soon as you start editing a document, a template is created, containing metadata about the fields (x, y, width, height, type of field, background color...) that is then tied to this document you created. Once you save, this template gets sent to the server. The template table consists of: template_id, document_id, fields (the metadata) as well as created_by_customer_id if you're a customer. As a result, someone else on the other side of the world opening the same document will see the fields you positioned already there – you just saved them the 5min it took you to position them. --- # What's the tech stack of SimplePDF? - NextJS on the frontend - Koa with GraphQL on the backend - Postgres (Managed Database on Digital Ocean) - A 10€ droplet on Digital Ocean --- If you have any questions, comments or feedback (good or bad), I'm all ears! --- [1] The assignments my estonian teacher gives me are usually scanned documents that do not have any editable fields in them.

Show HN: Reflame – Deploy your React web apps in milliseconds Hi HN! I've been working on Reflame since I quit my job at Brex last year, excited to finally open it up for everybody to try out! Here's a demo: https://www.youtube.com/watch?v=xZ4KyfGbUFA Reflame deploys client-rendered React web apps instantly, to previews and to production. In concrete wall-clock terms, deploys generally take: - ~50-500ms from our VSCode extension - ~500-3000ms from our GitHub app (Jump to this comment ( https://ift.tt/alL0dfw ) for what makes Reflame so fast) The Reflame GitHub App automatically deploys default branches to production, and other branches to previews. If you've used Netlify/Vercel's GitHub apps, you should feel right at home. The difference is it’s multiple orders of magnitudes faster. Fast enough that you'll probably never see an in-progress deploy on GitHub ever again , only ready-to-go preview/production links. No more having to babysit builds or having to context switch to and from other tasks before being able to see our changes deployed in previews or production. Previewing, sharing, and even shipping, can now become part of the so-called inner loop, giving us the superpower to stay in flow state for much longer. The Reflame VSCode extension is yet another order of magnitude faster than even the GitHub App. It was designed to offer an experience that can rival local development workflows in both speed and ergonomics, while addressing many of local dev's limitations around collaboration and production-parity. Every time we make a change (e.g. by saving a file), the extension will deploy that change (in ~50-500ms) to a "Live Preview", and will immediately update the app in our browsers to reflect that change. Live Previews can operate in one of two modes: - Development mode delivers updates through React Fast Refresh, offering the familiar state-preserving instant feedback loop we know and love from local development workflows. - Production mode delivers updates by triggering a full browser reload on every change, and in exchange for this extra bit of friction, we get to develop against a byte-identical version of the fully optimized production deployment that customers will see once we ship, with a tighter feedback loop than was ever possible before. Live Previews deliver updates over the internet, meaning we can effortlessly test out our changes on multiple devices simultaneously, and show our changes to anyone in the world, just by sharing a Live Preview link, all while having our updates reflected automatically across all connected devices in real-time (with live reload or React Fast Refresh over the internet ). Being able to ship quickly is valuable on its own, but Reflame's true north star has always been to enable customers to ship quickly with confidence . One way Reflame helps customers ship with more confidence today is by making previews with full production-parity available at every step of the development process. Previews in Reflame are accessible at the exact same URL customers will use to access the production deployment, instead of at a different subdomain for each preview (i.e. every preview is accessed through https://reflame.app instead of at https://ift.tt/TwuFJsX ). Behind the scenes, this is implemented using session cookies that our CDN will check to determine which version of the app to serve. This is only the tip of the iceberg. We have some really exciting prototypes around testing and typechecking that we've been exploring that could allow us to ship with even more confidence without ever slowing us down . If any of this sounds interesting for the apps you're building or planning to build (taking into account this comment ( https://ift.tt/Wfsad4M ) below describing what Reflame is not well suited for), please sign up and give it a try! I can't wait to see what you’ll build with it! :) https://ift.tt/EYOPTR8 October 8, 2022 at 10:40PM
Show HN: GreenSwapp – API to track CO2 of food products at scale Hi guys! We’re Ajay & Jainit, and we’re super excited to launch GreenSwapp to the HN community! GreenSwapp is an API that tracks product and recipe-wise carbon footprints at scale, for food products. Tracking carbon footprints of individual food products is hard because you’d have to trace it all the way back to the farm and account for all the energy inputs till the point of sale. Each such analysis takes about 6 months to do, and in many cases, it is hard to even map this journey. For food products that typically have multiple ingredients (i.e. they are recipes), you have to do this for each ingredient. Supermarkets have about 30k unique products per store. If you do the math, you’ll see that this quickly becomes impossible to do manually, in a reasonable amount of time. After my Masters’ in Sustainability & Engineering, I (Ajay) worked as a climate & impact consultant for more than a decade. I first discovered this problem 5 years ago (as I ran my own sustainability consultancy), when I saw some of my large food brand & retail clients struggling to identify their highest impact products & suppliers. More recently, we found that food platforms (such as Uber Eats & Yelp) want to track the climate impact of their recipes and restaurants too. We do the hard work of estimating carbon emissions using a combination of product meta-data / supply chain attributes (such as origin location, farming type, packaging type etc.) and aggregated product carbon footprints from peer-reviewed journals. Our core dataset is a comprehensive list of food types found in supermarkets. We use an ML model (semantic search using sentence transformers) to match queried product names to our standard list of product types and retrieve their median supply chain carbon footprints. This enables us to track impact at scale (thousands of products in minutes), making it easy and cheap for you to track product-level emissions. This would allow you to easily a) report emissions, b) identify high impact products, brands, and suppliers in your inventory, and c) communicate impact with consumers. What if my product is more sustainable? We identify every supply chain attribute that might reduce a product’s impact (such as organic farming, better packaging material, locally grown) and apply a correction factor (also obtained from peer-reviewed life cycle analyses papers). You can read more on our algorithm here - https://ift.tt/DGQrR9P You can try our API for free on any milk product (e.g. - Oatly oat drink barista edition) or any type of pizza (e.g. - Pepperoni pizza). Here are the API docs - https://ift.tt/UKofIuW . You can get your trial API key here - https://ift.tt/DGQrR9P . Our full API works with any food product you can find in the supermarket and any recipe. We charge a data license fee of $0.99 per product per year for supermarket products and $0.99 per ingredient per recipe per year for dishes. Here is a cost estimator tool - greenswapp.com/pricing. If you want to look up more than 100 products and 10 recipes, you also pay an annual platform fee (still figuring out the right price point). We’d love to get your feedback on our API. We are also trying to identify the biggest use case for this product. So please let us know what you’re using it for by commenting on this post - is it to use in a new app you’re building, get your company to use it at their cafeteria, reduce your company’s emissions, offset it, etc.? Any other ideas on how we can make this better would be wonderful too. Thanks a ton! https://ift.tt/UKofIuW October 5, 2022 at 10:00PM
Show HN: Speed of all of your processes across entire stack in one dashboard I built Checkpoints App out of my experience of not being able to quickly and easily measure the speed of processes across my tech stack in my startup. All startups optimize for speed in all of their operations: deploying code, responding to API requests, loading the UI, and in background processes such as sending emails to users or processing data in an ETL pipeline. But the tools available to measure the performance of all these operations are separate and time-costly to integrate, in the first place. Checkpoints App allows you to measure the speed of processes across your entire stack with minimal overhead and collects that data into a single dashboard. Integrating it into your tech stack is as easy as dropping a `print()` statement in your code, while you're writing it. It comes with client-side Python, JS and Bash scripts. You drop checkpoint statements anywhere in the code, defining a process name and checkpoint name, for example: `./checkpoints.sh process1 checkpoint1` where process1 is your process name and checkpoint1 is your checkpoint name. Once you've dropped checkpoints in your code. It will automatically create the process pipelines in your dashboard along with the speed metrics i.e, how long does it take, on average, to go from checkpoint1 to checkpoint2 . Then you can start optimizing for speed. Another major problem I saw was that most lightweight tools out there let you measure performance in a single part of your stack, for example, you need to use Lighthouse in the front-end UI and CloudWatch for your backend API endpoints. With Checkpoints App, however, you can create tailored processes across your tech stack. For example, you can add the first checkpoint in your backend and the second checkpoint in your front end.

Show HN: Music video using AI (Stable Diffusion) and a text editor – You can too I went nuts on Sunday after stumbling on this animator script for the automatic branch: https://ift.tt/zTQv4ER And then it's a ton of keyframing. I also found that the timings all have to be earlier than the timestamp you want to account for how long it takes to denoise to your new scene - so like .4 gives smoother but longer, .7 is snappy. To get stuff to keep showing up and stay dynamic you can zoom out continuously, it needs a UI, badly. If you're on windows you'll need ffmpeg too.

Show HN: placesloth.com – generate placeholder images of sloths Hey all, Last week I had to make a couple of test pages and turned to one of my favorite sites to fill it with some imagery: https://placebear.com/ There's a pretty large amount of sites like this, but none seemed to be serving the superior animal: sloths. So I hacked this together quickly over the weekend. It's definitely ugly code and an ugly approach, nothing prevents this from going OOM, it'll probably fall over under a bit of load (or when the single spot instance running it gets replaced), but it was fun to build and fills my needs. Hope this inspires you to expand the placeholder generator landscape, or at least include some sloths on your test pages :) https://placesloth.com/ October 3, 2022 at 01:55AM
Show HN: An ultra-light-weight tool to quickly test your ping Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH. It feels like there should be an easier way test my ping than puling up a terminal or a complex web app - especially when I'm on my phone or any other device that doesn't have a terminal. I figured I should be the change I wish to see in the world and created this super light ping test. I also created a latency monitoring solution ( https://ift.tt/M1lTR6F ), feel free to clone and try it out! I know there are a lot more mature monitoring solutions out there, but I never did figure out how to set them up. This one is super simple: clone it to some device that's always on, compile it, set up some systemd stuff, and it's ready to rock on port 8180! https://ift.tt/QrOoCxB October 2, 2022 at 02:01AM
Show HN: Sksql 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. https://ift.tt/U6KtvNJ October 1, 2022 at 09:24PM

Show HN: Another Darn To-Do List App Hi guys, This is my first time building something from scratch so go easy on me. I've always used to-do lists to keep me productive and stave off anxiety (not sure why they work so well for me but they do). I get kinda annoyed at the to-do list apps on the app stores because they move tasks to the bottom of the list when you tick them off. Some people may like that, but it annoys the shit out of me, because I like to feel a sense of progression as I go down through the list over the course of the day. So this was borne out of my frustration really. I also made it browser-based so it's easy to access the same list on all devices without installing apps on all of them. It's free to use. It's just something I made for myself and if others find it useful then that's great. I'd appreciate any feedback (there's a button to give feedback when logged in).

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/MS9teW8 September 18, 2022 at 12:05AM
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/L57I9v1 Docs: https://ift.tt/zugXm19 Announcement: https://ift.tt/wYWPoKj...

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 (combining XDP and a lockless FreeBSD tcp/ip stack) and a storage bypass.

Show HN: Stripe-quality API client libraries with a single button click TL;DR- Libninja will generate world-class client libraries for you, without you needing to fiddle with openapi-generator, maintain build pipelines, and so forth. If you just want Rust, reach out, and I'll create your client library at no cost, because I want to help Rust's ecosystem grow. -- Hi HN, I got into Rust in a big way about 9 months ago. While the language is quickly maturing, one large gap in the ecosystem is immature or non-existent client libraries for common API services like Plaid, Stripe, Twilio, Github, Slack, and so on. The existing openapi-generator templates create Rust libraries that don't even compile out of the box, so I started down the rabbit hole of creating a Rust-based toolchain to generate Rust client libraries based on an OpenAPI spec. Rust is an incredible language to build codegen tools in, because of algebraic data types, Rust macro system, and Rust's incredibly powerful libraries for AST transformation (quote, syn, and more - almost solely due to dtolnay - thank you!) Before long, I realized it's a common painpoint for API companies to maintain build pipelines, tweak openapi-generator templates, and so forth, to get client library generation working. I added support for more languages, and soon after, Libninja was born. If you're an API company, Libninja will generate world-class client libraries for you. Client libraries: - help your users integrate faster (meaning you get revenue faster) - reduce the number of bug reports and support requests (because there's no ambiguity about using your API) - Give your users a phenomenal developer experience (editor autocomplete, API documentation in docstrings, and more) PS- If you just want a Rust client, reach out, and I'll create your client library at no cost, because I want to help Rust's ecosystem grow. https://ift.tt/nEqxgrf September 12, 2022 at 11:15PM

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/XIO5UVt September 9, 2022 at 10:27PM

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/vhQXWcJ ) --- 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/hXZU87z... ). 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/jD7ManI https://crapple.mobi/ September 4, 2022 at 01:45AM

Show HN: Restfox – A web based HTTP client inspired by Insomnia and Postman Hey HN, I built this because I wanted a portable version of Insomnia I could access anywhere I am, without installing anything. The application is a PWA, so it will not load resources again after the first load, unless there's an update. It uses IndexedDB and loads quite fast even with a lot of nested requests and folders. Import from Postman and Insomnia is available making it easy to import your pre-existing request collections. Only limitation is that it only supports CORS enabled endpoints for now. I plan to add cors proxy support later on. There is of course the electron build ( https://ift.tt/ZDq9axM ), which can be used to bypass cors but that kinda defeats the portability of the app but it is an option.

Show HN: Reach 100 – a (unsolvable?) puzzle game I recently remembered a game we used to play with pen and paper some 20 years ago, where you need to fill a 10x10 grid writing numbers in the grid up to 100 following 2 simple rules. After showing it to my kids I thought it would be nice to adapt it digitally so that they could play it more often (not needing to draw the grid etc.) and so that other people could play it as well. What I'm really interested in with this submission (beyond general feedback) is wether anybody knows the origin of the game and if it's solvable. Because that's the catch, my highest score of all time is 97 and it doesn't seem to be possible to go higher. I have the feeling this game is an adaptation of a more general problem and probably has its origin in some lecture. So, once again, if you know where it comes from I'd be really grateful. Alternatively I would love to know if there is a possibility to prove if it's solvable or not. (It's made for mobile but it works on desktop as well with keyboard shortcuts around the S key in a QWERTY layout) https://reach-100.com August 31, 2022 at 10:42PM
