Show HN: I built a Red Flag Warning zone-check tool for the East Bay in 48h https://ift.tt/UWw9oE4

Show HN: I built a Red Flag Warning zone-check tool for the East Bay in 48h Hey HN. I'm a high schooler in Fremont, CA. Tuesday morning I got a county-wide AC Alert text telling everyone in Alameda County to prepare a go-bag for an East Bay Hills Red Flag Warning that starts tonight at 11 PM. The text went to ~half a million phones. The actual NWS warning polygon only covers East Bay Hills (NWS zone CAZ515). Most people who got the text don't need a go-bag tonight. Some in the hills don't realize how close they are. So I built this tool - https://ift.tt/sLA9zJ3 mit licensed public github - https://ift.tt/qsFWJ64 It does a few things - tells people if they are in the flagged zone, and also provides a way to check if a buddy is in flagged zone and send them a text. Everything without installing an app. I heard back from Oakland Firesafe Council director about a gap in my understanding (and the tool). To my surprise, and through feedback, I realized that you cannot assume that only the flagged area is at risk. Adjacent areas are at risk too! Fires do not follow zone boundaries! I fixed the tool. I built this in 48 hours to close that specific gap: type your address, get a yes/no on whether the NWS polygon covers it, your Genasys evacuation zone, tonight's wind + humidity at your point, a plain-English action checklist, a per-school decision view for East Bay districts, and a one-tap iMessage buddy-check template for a hill-neighbor at 10:30 PM. https://ift.tt/1oj253S June 11, 2026 at 02:16AM

Today an Oakland Firesafe Council director emailed me critiquing the "outside the polygon" framing as falsely reassuring — wind-driven fires don't respect polygons (1991 Oakland Hills, Lahaina, Palisades). I shipped a fix in an hour and the wording across every surface now reflects that. Open to any other critique. https://ift.tt/1oj253S June 11, 2026 at 12:13AM

Show HN: Sum Type and Type Matching in C Previous thread : https://ift.tt/XGefHyT Tried to implement a best effort pattern patching inspired solution in C. Destructuring not available, and nesting not directly available, but both can be achieved by opening more Match-When blocks. I guess we can say this is almost pattern matching in C. https://ift.tt/uqNkHzL June 9, 2026 at 11:18PM
