Show HN: I made an automated day-by-day itinerary organizer for my trip to Spain https://ift.tt/fxIwktl

Show HN: I made an automated day-by-day itinerary organizer for my trip to Spain For my solo food pilgrimage to the Basque Country, I pre-arranged flights in/out of Bilbao, Guggenheim Museum tickets, Michelin Guide restaurant reservations, bus tickets to San Sebastian and Saint-Jean-de-Luz, walking food tours and hotel reservations in each city, and a long list of pintxo spots to hit with notes on each one's food specialty. Most of this was poorly organized (manually) in my phone's Notes app, with references to specific emails for more information. I arrived on the first day in Bilbao, and the hotel didn't have me in their system by name, so I spent a good 10 minutes frantically scouring my emails for the confirmation number, cursing myself for holding up the people behind me. Over the course of the next few days, while I was relaxing at my hotel (after finally getting in) in between pre-planned stops, I started building a personal tool that would organize all of my bookings automatically and keep all relevant information at my fingertips. Thus, Petrel was born and named after one of my favorite birds. It started as a personal pet project but I shared it with some friends that were looking for something just like it so I ended up turning it into an app and website for all to benefit. It's completely free to try without even signing up. On my next group trip, I built out logical collaboration features to allow groups to vote, split expenses, share notes, and add pictures all within the same ecosystem. I've slowly improved the parsing and itinerary logic and built in convenient features such as weather, estimated travel times, an encryption-protected area to store copies of personal information, and a comprehensive travel log with fun stats. I also made it so that the parsing tool can accept almost any file type. However, the tool doesn't do anything to assist on the planning side and doesn't provide true flight alert pushes, despite having live flight status syncing. I would love for more people to test it out, challenge the parser, and let me know their thoughts and experience. https://ift.tt/QamLdz3 September 14, 2026 at 01:47AM

Show HN: VibeWorld – a shared terminal world for developers and scientists https://ift.tt/tNHzcpC

Show HN: VibeWorld – a shared terminal world for developers and scientists Vibeworld is a persistent cyberpunk shared world that runs in your terminal, where you can meet other developers and scientists to have company at 2 AM while screaming at your LLM :) you can connect with other scientist, chat, and includes also use vocal chat if you want to use it. There is a world and a moon, and they are completely 3D rendered and animated. In the moon there is the "complaint crater": a place where you can scream an insult against your claude or codex session and everybody from the space can see it. You can create your pixel avatar! There is also the "stargazing ledge": a place where you can see the stars and whatever happens in the sky. You can chat in the meantime if someone else is there too, or just watch our Earth. Sometimes you can see galactic wars, and there is a plant that grows but dies if nobody waters it. You can leave it on the second monitor while working (it does not use a lot of RAM): watch the sky when you want, and sometimes you may chat with some other scientist in your same situation. In the world, continents are scientific macroareas, and cities are specializations: you can create your corners where you can speak and help others (but for now it is quite empty). You can install in one command and by just typing "vibeworld" in your terminal, you are inside the world. There are some games inside and a sort of Doom where enemies says to you "Retracted" or "dedline tomorrow" when shooting you :). There is also an awkward reason why I am posting the work here. I have just discovered that another product Vibeworld.build uses the same name and the same concept (shared multiplayer world for developers). I don't know how independently it was developed. It is not a TUI, but it is a full, paid application developed by a company after my project was released. To be honest luckly I find my project more funny. I do care about preserving the chronology, my VibeWorld was released before, and there are verifiable timestamps in the GitHub. I just don't want the original public record to disappear if a much larger implementation of a very similar concept gets more attention later. I would like to hear what people think about it! :)) https://ift.tt/c3EpDnX September 14, 2026 at 12:00AM
