Show HN: Auto-VPN – Deploy temporary WireGuard servers with automatic cleanup https://bit.ly/49HNjlZ

Show HN: Auto-VPN – Deploy temporary WireGuard servers with automatic cleanup Auto-VPN is a self-hosted tool that lets you deploy personal WireGuard VPN servers on-demand and automatically removes them when they're not in use. I built it to avoid paying for VPN subscriptions and to make temporary secure connections easier to manage. *Key features:* - One-click WireGuard server deployment on Vultr/Linode - Automatic server cleanup when inactive (configurable: 30min/1h/2h/4h or custom) - Simple web UI for server management - Downloads WireGuard configs directly The cleanup feature monitors WireGuard connections - if no peers are connected for your set period, the server is automatically destroyed to save costs. You can adjust this timeout in the UI. GitHub: https://bit.ly/3P1cAOC Looking forward to your feedback! https://bit.ly/3P1cAOC December 16, 2024 at 09:30PM

Show HN: Convert PDF invoices to e-invoice XML using AI in seconds https://bit.ly/3OZaNcE

Show HN: Convert PDF invoices to e-invoice XML using AI in seconds I got approached by the finance department of a large company. There is a new regulation in Europe that mandates a defined XML-format for e-invoices for some transactions and - I kid you not - their SAP implementation wasn't able to address this. They also said that all solutions on the market were either cumbersome (think: manually typing in all fields) or required deep system integration. I thought it cannot be that hard to use AI for this and built a little invoice converter that takes your PDF invoice in whatever form it is, and outputs exactly the XML structure that is required in the regulation. Given that AI is not perfect (but surprisingly close to it!), you can manually edit all fields. Target users are companies where their current solution does not yet support the standard and that do not want to change their existing invoicing flow (incl. foreign businesses). Trying it out is free. Given this is my first real B2B tool, would love some feedback! https://bit.ly/3OY0l5e December 16, 2024 at 10:52PM

Show HN: Socratify: Learn by Debating – critical thinking coach https://bit.ly/41Ftbij

Show HN: Socratify: Learn by Debating – critical thinking coach Socratify is an AI coach for early stage professionals to sharpen their critical thinking and verbal communication skills Ever since ChatGPT came out, I've been using it to debate and learn new ideas. Having a short insightful conversation where AI coaches you can be powerful but it's hard to get right with a general purpose chat LLM because they don't propose stories, lack context and don't track progression I'm building Socratify with the hypothesis that a product built around AI questioning humans and proposing interesting questions daily can be 100x more rewarding than book summaries and other passive content. Inspired by Charlie Munger's concept of a latticework of models that you apply to new situation. Socratify teaches you a concept (e.g., Disruption), discusses a situation where it's applicable, (e.g., Google vs. Perplexity) and gives you feedback as well as the strongest counterargument Checkout the first release at https://bit.ly/3OUoFVI Appreciate thoughts from the HN community and would love to learn what you would want from an AI coach that makes you better every day (Note you have to sign up to use but 5 stories are free) https://bit.ly/3OUoFVI December 16, 2024 at 03:55PM

Show HN: Aldren Quest – Browser RPG https://bit.ly/3ZVLpLm

Show HN: Aldren Quest – Browser RPG Hello everyone! I've finally finished my latest side project - a RPG game made in Blazor. It started as a small project to learn some Blazor (I'm .NET dev but kept mainly to backend and ASP.NET). I had such a good time coding it that at some point I decided to make a full featured game out of it. I might've have bitten off more that I could chew as RPGs have so many systems and elements but overall I think it worked out well, especially for a single person project. I want to hop on the next project soon so any comments/questions/tips than can make me better really appreciated! https://bit.ly/3ZUjr2l December 16, 2024 at 01:50PM

Show HN: Shop Clothes with Models That Match Your Body Shape https://bit.ly/3VEpaqC

Show HN: Shop Clothes with Models That Match Your Body Shape This is one of those fix a problem you can’t ignore projects. Like most online shoppers, I often found myself frustrated: clothes look great on models but disappoint when I try them on. It’s not the clothes, it’s the body shape mismatch. So, I spent the last few months building TheBodyMatch, a platform where clothes are showcased on models who share your body shape. You get a more relatable and confident shopping experience because seeing is believing, especially when the model reflects you. It’s still early days. Think of this as a beta where feedback is gold. I’d love for you to try it out here: https://bit.ly/4ivb4lj and share your thoughts. Is this the future of online fashion? I hope so. https://bit.ly/3ZTOOKr December 15, 2024 at 10:54AM

Show HN: Wool Ball – Decentralizing AI with Distributed Browsers https://bit.ly/4gude2w

Show HN: Wool Ball – Decentralizing AI with Distributed Browsers Hi HN, I recently launched Wool Ball ( https://bit.ly/4fmjrg2 ), a project designed to test the concept of paying people to enable their devices to process AI tasks through their browsers. The idea revolves around “browser as a service” or “browser as a server,” leveraging idle browser resources to create a decentralized, scalable, and cost-effective way to run AI workloads. We’re still in the early stages, and I’d love to hear your feedback on the concept and the product we’re building. Overview: https://bit.ly/4iDiQcI What do you think of this approach to decentralizing AI? December 14, 2024 at 12:08AM

Show HN: Performant intracontinental public transport routing in Rust https://bit.ly/3ZsTW6Y

Show HN: Performant intracontinental public transport routing in Rust I made a public transport route planning program that's capable of planning journeys across Europe or North America! There's only one other FOSS project I know of (MOTIS/Transitous) that can do transit routing at this scale, and in the testing I've performed mine is about 50x faster. I've spent a few weeks on this project now and it's getting to the point where I can show it off, but the API responses need a lot of work before they're usable for any downstream application. Example query (Berlin to Barcelona): https://bit.ly/3ZE0bom... There are some bugs still. Notably, it's not capable of planning the return trip for this route, nor the reverse of the trip from Seattle to NYC that I gave in the blog post. Blog post: https://bit.ly/3ZzZdtw... Repo: https://bit.ly/3ZCgBh3 Side-note but in the past some have criticized my writing style and it's been a bit hurtful at times but if you have constructive feedback on the blog post I'd appreciate it. I'm trying to get better at writing. :) https://bit.ly/3ZCgBh3 December 14, 2024 at 01:00AM

Show HN: I designed an espresso machine and coffee grinder from scratch https://bit.ly/3VDAROp

Show HN: I designed an espresso machine and coffee grinder from scratch It was a lot of work as a solo project but I hope you guys think it’s cool. When I say “we” in the website it’s only in the most royal sense possible. I also did all the photo/videography. I started out designing a single machine for personal use, but like many things it sort of spiraled out of control from there. I felt like espresso machines were getting very large, plasticky, and app-integrated without actually improving the underlying technologies that make them work. The noisy vibratory pumps in particular are from 1977 and haven’t really changed since then. So I wanted to focus on making the most advanced internals I could and leaving everything else as minimalist as possible. The pump is, as far as I know, completely unique in terms of power density and price. Without spending several thousand dollars, it was difficult to find a machine with a gear pump, and adjustable pressure was also similarly expensive but this machine has those things and costs a normal amount to buy. You can also turn the pressure way down and make filter coffee. I also saw so many people (including myself) using a scale while making espresso, and even putting a cup below the group head to catch drips, entirely negating the drip tray, so I basically designed for that! The profile of the machine is much lighter on the eyes and doesn’t loom in the corner like my old espresso machine did. And for the grinder, basically everything on the market uses conical and flat burrs that have descended from spice grinders, and the same couple of standard sizes. Sometimes larger companies design their own burrs, but only within those existing shapes. There is sort of a rush to put larger and larger burrs into coffee grinders, which makes sense, but with cylindrical burrs, you can increase the cutting surface way more relative to the size of the grinder. When grinders get too big, maintaining alignment becomes mechanically cumbersome, but the cylindrical burr can be very well supported from the inside, and there is the added benefit of hiding the entire motor within the burr itself. The resulting grounds are just outright better than all the other grinders I have used, but obviously this is a matter of taste and my own personal bias. The biggest downside for the grinder is that it doesn’t work with starbucks style oily roasts, because the coffee expands so much while traveling down through the burrs and can sometimes clog up the teeth. It doesn’t hurt the grinder but it does require cleaning (which is tool-free!). Another downside for both machines is the fact that they run on DC power so it’s best if you have a spot in your kitchen to tuck away the power brick. I also made a kit that makes the gear pump a drop-in upgrade for other espresso machines, to reduce noise and add adjustable pressure. https://bit.ly/4fm0z0K The roughest part of this process were the moments midway through development where they weren’t working at all. When the grinder is just jamming itself instantly or the fourth factory in a row tells you the part you’re making is impossible or the pump is alternating between spraying water out the side and into your face and not pumping at all. And the default thought is “Of course it’s not working, if this was going to work someone else would have already made it like this”. The route you’ve taken is fundamentally different enough that there are no existing solutions to draw on. You’re basically feeling around in the dark for months on end, burning money, and then one day, every little cumulative change suddenly adds up to a tasty espresso. And it’s not perfect yet, but you at least can see the road ahead. Anyways, this is way more than I expected to write, thank you for reading!
