New best story on Hacker News: Show HN: OpenFreeMap – Open-Source Map Hosting

Show HN: OpenFreeMap – Open-Source Map Hosting 546 by hyperknot | 165 comments on Hacker News. Hi HN, After 9 years of running my own OpenStreetMap tile server infra for MapHub ( https://ift.tt/7EWrHbJ ), I've open-sourced it and launched OpenFreeMap. You can either self-host or use our public instance. Everything is open-source, including the full production setup — there’s no 'open-core' model here. Check out the repo ( https://ift.tt/tf7YIR6 ). The map data comes from OpenStreetMap. I also provide weekly full planet downloads both in Btrfs and MBTiles formats. I aim to cover the running costs of the public instance through donations. Looking forwards for your feedback.

New best story on Hacker News: Show HN: I Wrote a Book on Java

Show HN: I Wrote a Book on Java 526 by goostavos | 139 comments on Hacker News. https://ift.tt/o0cOxDX... This book is a distillation of everything I’ve learned about what effective development looks like in Java (so far!). It's about how to organize programs around data "as plain data" and the surprisingly benefits that emerge when we do. Programs that are built around the data they manage tend to be simpler, smaller, and significantly easier understand. Java has changed radically over the last several years. It has picked up all kinds of new language features which support data oriented programming (records, pattern matching, `with` expressions, sum and product types). However, this is not a book about tools. No amount of studying a screw-driver will teach you how to build a house. This book focuses on house building. We'll pick out a plot of land, lay a foundation, and build upon it house that can weather any storm. DoP is based around a very simple idea, and on

New best story on Hacker News: Show HN: iFixit created a new USB-C, repairable soldering system

Show HN: iFixit created a new USB-C, repairable soldering system 647 by kwiens | 315 comments on Hacker News. After years of making screwdrivers and teaching people to repair electronics, we just made our first electronic tool. It's been a journey for us to build while hewing to our repairable principles. We're really excited about it. It's a USB-C powered soldering iron and smart battery power hub. Super repairable, of course. Our goal is to make soldering so easy everyone can do it: https://ift.tt/oKhlEjC We didn’t want to make just another iron, so we spent years sweating the details and crafting something that met our exacting standards. This is a high-performance iron: it can output 100W of heat, gets to soldering temperature in under 5 seconds, and automatically cools off when you set it down. The accelerometer detects when you pick it up and heats it back up. Keeping the iron at a lower temperature while you’re not soldering shouold prolong the life of the tip. Wh

New best story on Hacker News: Ask HN: Why is Pave legal?

Ask HN: Why is Pave legal? 676 by nowyoudont | 267 comments on Hacker News. If you haven't heard of it, Pave is a YC-backed startup that helps startups with compensation. I can't actually access the system so I'm speaking from hearsay and what's information on public parts of their website. The way I understand it works is that you connect Pave to your HR and Payroll systems, they take the data about who you employ and how much you pay them, combine it with all their other companies, and give companies a collective breakdown of compensation ranges. My question is, isn't this specifically anti-competitive wage fixing? This seems exactly like RealPage but for employee compensation. As far as I know, colluding on wages like this is illegal. Is there something about the company that I'm missing?

New best story on Hacker News: Show HN: Infinity – Realistic AI characters that can speak

Show HN: Infinity – Realistic AI characters that can speak 468 by lcolucci | 292 comments on Hacker News. Hey HN, this is Lina, Andrew, and Sidney from Infinity AI ( https://infinity.ai/ ). We've trained our own foundation video model focused on people. As far as we know, this is the first time someone has trained a video diffusion transformer that’s driven by audio input. This is cool because it allows for expressive, realistic-looking characters that actually speak. Here’s a blog with a bunch of examples: https://ift.tt/sFcxQZI If you want to try it out, you can either (1) go to https://ift.tt/B7NMnys , or (2) post a comment in this thread describing a character and we’ll generate a video for you and reply with a link. For example: “Mona Lisa saying ‘what the heck are you smiling at?’”: https://bit.ly/3z8l1TM “A 3D pixar-style gnome with a pointy red hat reciting the Declaration of Independence”: https://bit.ly/3XzpTdS “Elon Musk singing Fly Me To The Moon by Sinatra”: https:/

New best story on Hacker News: Show HN: Wealthfolio: Private, open-source investment tracker

Show HN: Wealthfolio: Private, open-source investment tracker 551 by a-fadil | 175 comments on Hacker News. Thank you for your comments, just some context: - The app is a simple desktop application that works on macOS, Windows, and Ubuntu. - I developed this app for my own needs. Getting tired of SaaS app subscriptions and privacy concerns. - For now, the activities are logged manually or imported from a CSV file. No integration with Plaid or other platforms. - No monetization is planned for now (only a "buy me a coffee" if you use and appreciate the app).

New best story on Hacker News: Tell HN: Burnout is bad to your brain, take care

Tell HN: Burnout is bad to your brain, take care 519 by tuyguntn | 209 comments on Hacker News. I am depressed and burned out for quite some time already, unfortunately my brain still couldn't recover from it. If I summarize the impact of burnout to my brain: - Before: I could learn things pretty quickly, come up with solutions to the problems, even be able to see common patterns and see bigger underlying problems - After: can't learn, can't work, can't remember, can't see solutions for trivial problems (e.g. if your shirt is wet, you can change it, but I stare at it thinking when it is going to get dried up) Take care of your mental health
