Show HN: LogLineAlign: Merge logs from different time zones into one timelinehttps://loglinealign.com
https://loglinealign.com/ I vibe-coded an application that merges entries from multiple log files into a single, chronologically ordered view. It handles timezone offsets and can auto-detect some timestamp formats, with an option to specify the format manually. Files are processed on your device and not uploaded to a server. It's all open source: https://github.com/jftuga/loglinealign In the repo, there is a quick, 3 minute narrated explainer video as well as a CLI version.

I've been a photographer for decades, and for a long time I've wanted to make an app that will tell me when the sun's light will directly hit the/a surface of a building. This weekend I found the time to build and launch a thing that does that. Features include: - Enter an address, get back a map with calendar details and some dataviz on when the sun is going to hit each wall - Save buildings, walls, and dates in a Planner, with a Calendar feed - Analyze the sun between two points along a street (currently limited to 5km along a single street) - Share links to what you've found Sources used iβ¦

The Enso Method is a new set of AI skills for Claude Code and Codex which I've open sourced on GitHub predominantly for developers who build for someone else who is making the product/business calls. I've been using AI to write basically 100% of my code since late 2024, back in the Sonnet 3.5 days, when it barely worked and there were few people doing this and very little support for this way of developing. I stubbornly thought this was going to be the future and came up with a methodology for making it work, before "AI skills" were even a thing. Since then I've continued to refine the methodβ¦

I've been working on this app for a couple months, because I needed help outlining my story being written on Google Docs. I kept adding new characters, and it was difficult for me to keep track of everything going on in the story. I wasn't organized at all. I do have a subscription to Claude, and it helps, sure, but it didn't exactly build a graph of all the story elements connecting together.

Hey HN, Iβm Vishnu from Agent37 ( https://agent37.com ). We build sandboxes for running AI agents at under 10% of the cost of most sandbox providers.
