Show HN: An icon for every city in North America https://ift.tt/7a4bq0L
Show HN: An icon for every city in North America To my knowledge there is no icon pack for cities in NA below a certain size. So I created one! An icon for every city in NA with >100k population. 544 in total. Generated with Nano Banana Pro. These cost me ~$70 to generate. Giving away for free! Some exceptions are 1 city for each US state that didn't have a city above 100k population such as Burlington Vermont. I also took liberties with what icon was used such as Whale Tales for BTV. Surprisingly, smaller cities have many comp…
Show HN: Replacing CAPTCHAs with adaptive proof-of-work in WordPress https://ift.tt/5F7hQu6
Show HN: Replacing CAPTCHAs with adaptive proof-of-work in WordPress When I founded my business a whistle-blowing-service for enterprises, I’ve seeked for a working solution to block spam bots on that home page. The solution was intended to comply with EU data privacy law, no cookies, no sniffing, light-weight-size, on my webserver only, beeing invisible for my site visitors and no running costs at all. I came across Hashcash, a proof-of-work approach, to block spam. When I implemented it, it worked immediately and blocked 100 percent without …
Show HN: ZeGrapher v4: modern math plotter https://ift.tt/oK4jC6D
Show HN: ZeGrapher v4: modern math plotter ZeGrapher is a free an open-source math plotter, first release in 2011 (I thought there were no such app on Linux at the time), that I kept sporadically updating ever since. Last version was 6 years ago but a lot of work went into it. v4 is a near complete rewrite to a modern interface and approach, inspired by desmos. Interesting differenciating features: - Computing and plotting recursive sequences - svg and pdf export at the physical size you see or set on your screen, in centimeters - "schro…
Show HN: Omnara – Open-Source Alternative to Claude Managed Agents https://ift.tt/KwAEoPq
Show HN: Omnara – Open-Source Alternative to Claude Managed Agents Hey y'all, Kartik from Omnara ( https://omnara.com ) here. We're building an open-source API for running durable agents. You create an agent with an API call, and Omnara runs the agent loop, gives the agent sandboxes to run commands in, and handles secrets, permissions, and RBAC. Each agent's state is stored in Postgres, so agents survive restarts and cost nothing while idle. You can message them and stream their events over the API. You may remember us from our ear…
Show HN: Overdesigned Simple Solitaire https://ift.tt/ZGEVW2f
Show HN: Overdesigned Simple Solitaire I got irritated by the maximalism and lack of aesthetics present in modern software when trying to find a nice solitaire. A solitaire does not need a score, levels - and most of all it does not need to download anything, have user log in or do anything else except maintain game state. So since software comes automatically nowadays, I decided as a weekend project to create the last solitaire I'll ever need. The application is built on Rust so I can compile it to native. But it runs just as well as web …
Show HN: Dovepass – can I legally fly a drone along this exact path in SF? https://ift.tt/uqHUgC0
Show HN: Dovepass – can I legally fly a drone along this exact path in SF? Dovepass answers one question for drone operators: given two points, can a drone legally fly between the two points? I build route planning for delivery drivers and wanted to check what it would look like if the vehicle flies. Drone navigation is different from land-based vehicle navigation. In addition to road and traffic data, it requires data on buildings, building height, wind speed and direction, and total load, including the payload a drone might carry. It is also…
