Show HN: Have voice-only virtual coffees with fellow HN'ers https://bit.ly/3ZhAtVU

Show HN: Have voice-only virtual coffees with fellow HN'ers I'm running several voice-only virtual coffee events on the Discord server in the URL, only for today. The rules are pretty simple: 1. Wait for the "event" to start (see times at the end) 2. If there are no tables with 1 participant, join any one. 3. If there is a table with 1 participant, join that one. 4. When the event ends, all the voice channels are deleted and you have to wait till the next event starts. I initially wanted to build my own web app but then I realised it would be so much easier to just leverage Discord's infrastructure. I also built a bot in a couple hundred lines of Go code (love the language!) to bulk create/delete voice channels. I intentionally left it super basic to validate if there's a need. I personally would love to have virtual networking events, but then again I know I'm somewhat odd as I come from a sales background. If you're interested/want to take part in more of these events, check out my profile where I have some contact options. Anyway, here's the times (each lasts 1 hour): - 8 AM GMT / 1.30 PM IST / 12 AM PST - 11 AM GMT / 4.30 PM IST / 3 AM PST - 2 PM GMT / 7.30 PM IST / 6 AM PST - 5 PM GMT / 10.30 PM IST / 9 AM PST - 8 PM GMT / 1.30 AM IST / 12 PM PST - 11 PM GMT / 4.30 AM IST / 3 PM PST https://bit.ly/3IzPkFq January 8, 2023 at 07:59AM

Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ https://bit.ly/3Iqr6gG

Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ Hey HN: Kaveh here, the founder of https://bit.ly/2Z5ZKFQ 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 tens of millions of dollars in spend and have a lot of liquidity, so we take on very little risk. We make money off of a 20% Savings Fee. Happy to chat directly kaveh@usage.ai Have you experienced any issues with managing your company or organization's AWS expenses? We'd love to hear your feedback and ideas! January 7, 2023 at 04:45AM

Show HN: ACOS: Build and share competitive turn-based browser games https://bit.ly/3IwoVIr

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 events - Simple deployment and version management It's a ridiculous endeavor, but I'd like to invite the world to my playground and help me drive features and technology forward. I may allow AI bot battles in the future against any of the hosted games, but I will prioritize based on the will of the people.

Show HN: Track and share your technical interview prep progress https://bit.ly/3jRwBKZ

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: Point Cloud Utils – A Python library for 3D point clouds and meshes https://bit.ly/3iikztC

Show HN: Point Cloud Utils – A Python library for 3D point clouds and meshes This is a utility library I slowly built up during my PhD and has become my swiss army knife for processing 3D data. It's super easy to install (only depends on NumPy and SciPy). The goal of the library to have an extremely simple API for geometry processing which uses NumPy arrays as a core data structure (so it can be dropped into whatever numerical codebase you're working with). Most of the library is written in C++ using a custom binding framework ( https://bit.ly/3iikAha ) that I wrote which avoids copies when converting NumPy arrays to Eigen Matrix types. Happy to answer any questions you might have about it and I hope Point Cloud Utils is useful to you! https://bit.ly/3iikBBK January 5, 2023 at 05:02PM
