Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ https://ift.tt/WEO7l2u

Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ Hey HN: Kaveh here, the founder of https://www.usage.ai/ We help companies drive down AWS EC2 spend by buying and selling 3-year no-upfront reserved instances. Why? Because there's almost no liquidity on the AWS EC2 RI Marketplace and it can take a while, if at all, to sell an RI if you need to stop using one. Previous to founding Usage, I worked at JPMorgan Chase as a summer analyst. Here's how it works: We are typically brought in by a DevOps manager to cut AWS EC2 costs. The app is entirely self-service and the savings are generated automatically, typically we do this live on a call. On average, we reduce AWS EC2 spend by 50% for 5 minutes of work. To reduce by 50%+, we've built a pool of reserved instances that's shared across our pool of customers. When a customer scales up their EC2s, Usage buys RIs. When a customer scales down their EC2s, Usage sells RIs. At this point, we've saved companies t

Show HN: ACOS: Build and share competitive turn-based browser games https://ift.tt/DnEiqV0

Show HN: ACOS: Build and share competitive turn-based browser games Hi everyone, This is a little tech demo I've been working on the past 2 years. It's been up for 1 year now, and has since had a few major updates. I have a soft spot for games with ranking systems, and I wanted an easy way for developers to create games with the competitive element abstracted away. The current games are built with ReactJS, so it's pretty easy to onboard if you are a web developer. All games developed for ACOS come with these features: - Real-time turn-based for browser - Simulator for game development - Client / Server architecture - Easy multiplayer with simple JSON game state update - Single player, Team-based, Battle Royale, and Free-for-all games supported - Matchmaking for Rank / Casual play - Room Scoreboard - Game Replays of every match - Error Logs - Global Rankings - Global Top Scores - GitHub Integration with acosgames organization - Discord Integration for matchmaking / game even

Show HN: List of Stripe Alternatives https://ift.tt/OQRjICE

Show HN: List of Stripe Alternatives Seems like every time there's a negative Stripe story on here, the inevitable question, "any alternatives?" gets asked. Hell, I was tempted to ask myself. Instead, I decided to search hn.algolia.com to see for myself what others have recommended in the past. Might as well share the list with y'all, make it meta. -- 2Checkout | https://ift.tt/FUvmRTP Adyen | https://www.adyen.com Amazon Pay | https://pay.amazon.com Authorize.net | https://ift.tt/lhfZBj5 Balance | https://ift.tt/cjYSh9v Braintree | https://ift.tt/1fQGcbk ChargeBee | https://ift.tt/e9ITCZb Chargify | https://ift.tt/Iikf8cP Checkout.com | https://ift.tt/Ydex1O6 DigitalRiver | https://ift.tt/rE5HaW3 Dwolla | https://www.dwolla.com FastSpring | https://fastspring.com GoCardless | https://gocardless.com MangoPay | https://ift.tt/Q6jLrtc Mollie | https://www.mollie.com Opayo (previously SagePay) | https://www.opayo.co.uk Paddle | https://www.paddle.com Payoneer | https://i

Show HN: I spent 2 years building Tablane as a 17-year-old https://ift.tt/TEicnMx

Show HN: I spent 2 years building Tablane as a 17-year-old Hi HN community, I'm Marcus, a 17-year-old Software Engineer from Germany. For the past two years I've been working on Tablane [0]( https://ift.tt/Xnupd7V ) a task/project management tool, with features like: - Collaborative Editing (google docs) - Optimistic updates with RTK Query - Realtime sync with Socket.io - An awesome design Let me know what you think! Ask me anything! How I got here: 2020: I was developing a TTT [1] (Trouble in Terrorist Town) plugin for my minecraft server, when I started to require a project management tool to keep track of the features I wanted to implement, originally I used a text file, but after some time I started using products like ClickUp and Monday. But not long after I hit several paywalls for features that I wanted to use (Custom Status, Limited Number of Boards, ...) Soon after Tablane (originally task-board) was born. I started building the website using plain HTML, then found out

Show HN: Track and share your technical interview prep progress https://ift.tt/UyPpGo3

Show HN: Track and share your technical interview prep progress A few friends and I just launched a web app to help people prepare for technical SWE/SDE internship interviews! We want to make it easier for people to prepare for interviews, especially for some of the largest tech companies. Core features include easy progress tracking, one-click link sharing, company-specific lists, and topic & difficulty-wise problem filtering. The problem list isn’t exhaustive and we are still looking for more open-source data to make our list more extensive. We want to hear about the bugs you find as this is the beta version. If you have any improvements to suggest, we are all ears! Our code is also completely open-source!

Show HN: Ello (YC W20) – AI-reading tutor for kids that works with real books https://ift.tt/MJgYu4a

Show HN: Ello (YC W20) – AI-reading tutor for kids that works with real books Hi HN, We’re Elizabeth, Catalin, and Tom - the founders of Ello ( https://ift.tt/vjozqVg ). Ello is an AI-powered app that mimics the one-on-one interaction of a reading tutor by listening to, encouraging, and coaching kids grade K-3 as they read out loud from a real book. We posted on HN back in 2020 when we launched Trustle, a company designed to pair families with dedicated experts in child development. We learned from that experience that parents don’t want a consultant, but they do want actual help with specific challenges—one of the biggest being reading. Prior to COVID, 65% of 4th graders in the U.S. were reading behind level. The most recent National Assessment of Educational Progress report revealed that reading levels have dropped even further, to the lowest level since 1992. These disheartening statistics reinforce something we learned during our time at Trustle—of all the pain points parents face

Show HN: An open source tool to generate Jet Engine compressors Hi everyone started this project a year ago to generate the CAD for a Jet Engine Axial Compressor. I am now open sourcing this tool that can take in a JSON file with specs and generate the CAD assembly. Still has a lot of work to improve designs but there isn't anything the Open Source community can't accomplish! https://ift.tt/ebAQVHS January 5, 2023 at 12:52AM

Show HN: Spall – WASM-based profiler for JavaScript and C in ~5k lines of Odin https://ift.tt/Qzdo36H

Show HN: Spall – WASM-based profiler for JavaScript and C in ~5k lines of Odin [I'm the author] Spall is a web-accessible profiler that I made to help my web-dev friends load gigabyte+ JSON traces without lunch-break-long load times. Recently, Spall got experimental support for auto-tracing with binary traces (along with an in-progress native-port, to give it more memory headroom), which was used to help track down and fix some hard-to-spot lock contention issues in the Odin-language compiler. I demoed it at the Handmade Seattle conference in October, https://ift.tt/ajU5GPy , with a head-to-head against Perfetto, another big web profiler. I'll be around to answer any questions. Thanks for looking at my project! If you like Spall, you can catch my other projects over at https://ift.tt/bkWZzmv . If you happen to be hiring I'd love to hear from you. Looking for something fun and new to do after a long sabbatical, working on cool open-source projects! https://ift.tt/HUcbult Jan

Show HN: Banger–A Firefox extension to extend DDG's bangs https://ift.tt/0mOMdcg

Show HN: Banger–A Firefox extension to extend DDG's bangs Hello HN! I made this Firefox extension to extend upon DuckDuckGo's idea of bangs (check https://ift.tt/ABs3xJp if you aren't familiar with them) and also allow the use of any search engine with them. I found DuckDuckGo's bangs fascinating, but was disappointed by how little search engines inherit that feature. And on top of it, DuckDuckGo has the "!" bang that jumps to the first search result but other search engines offering bangs like Brave Search, searx, You.com don't seem to have that. I also thought that the "!" bang could be extended with the ability to jump to the first search result of a specific site, so I added the "!!" bangs in my extension that allow you to do just that (e.g. typing "!!mdn flatMap" will bring up the MDN page for flatMap). I also added a bunch of extra features like the ability to add custom bangs, ability to search in a search engine with t

Show HN: Isitongamepass.gg https://ift.tt/MXjY9Pm

Show HN: Isitongamepass.gg Xbox Game Pass is pretty amazing. However, the official website to list games is horrible. It takes forever to load, it's hard to navigate, and weirdly difficult to just look up if a game you care about is available on Game Pass. Enter https://ift.tt/XVjUNmP - a super fast site where you can look up the current Game Pass roster. My goals going into it were speed and easily accessible information. Each card has a game title, a poster image, and the set of platforms it's available on. If you click on a card, it opens up a details view that has links to the store page for the game as well as a description and availability details. This is something I put together in my free time and is the first website I've built (although I'm a professional software engineer) so I have no doubt there are some bugs. If you run into something, please comment here or send me a DM. Same goes if you have ideas for improvements! A couple other random things: Why are

Show HN: Detecting collision between 500k circles below 5ms https://ift.tt/DSMLU59

Show HN: Detecting collision between 500k circles below 5ms Heya. I created a flexible collision engine for broad detection in C that's also pretty fast. Personally that's my best, so I wanted to show it here. Although... still not as fast as DragonEnergy's one that supposedly handled millions of agents bouncing off each other every frame on an old i3, haha. I hope I get better at this! He set the bar pretty high for me. I was considering including some small function that tries finding the nearest entity, although I think it might be better to simply use query for that matter. Perhaps in the future I will get a good idea of how to do that more efficiently. This is not a clickbait. Although generally you also call other functions in a tick, a collision check between 500,000 circles ("circles", not "squares", because distance is checked and forces are applied based on the angle between) is done below 5ms on not really that demanding hardware. I achieve lo
