Show HN: Safe-now.live – Ultra-light emergency info site (<10KB)(safe-now.live)
After reading "During Helene, I Just Wanted a Plain Text Website" on Sparkbox (https://news.ycombinator.com/item?id=46494734) , I built safe-now.live – a text-first emergency info site for USA and Canada. No JavaScript, no images, under 10KB. Pulls live FEMA disasters, NWS alerts, weather, and local resources. This is my first live website ever so looking for critical feedback on the website. Please feel free to look around.

I like this! I noticed that the weather for some Bay Area counties seem to be getting zeroed out for temperature.

(both say: Weather Now 32°F / 0°C - Sunny )

I've been working on a similar idea for travelers, https://travelsafetydata.com/

It's pulling the travel advisories from US/CA/UK/IE/AU/NZ and aggregating the results/information to help you understand the risks of different countries. It also pulls from other sources for basic country info/risks (eg. women, lgbtq).

Yours is way lighter weight and focused, very cool!

How are these "scams & fraud"?

> Make sure your health insurance plan provides coverage overseas. Most care providers overseas only accept credit card payments. See our webpage for more information on insurance overseas. Visit the U.S. Centers for Disease Control and Prevention for more information on the type of insurance you should consider before you travel overseas.

> Gas stations in rural areas can be far apart. Some stations are unattended and require a credit card with a chip to purchase fuel.

Same with https://travelsafetydata.com/country/NO

It lists child protection laws as "scams & fraud"

Yeah that scraper is... not fully ready yet, why I put BETA label on it.

Room for improvement. Thanks :)

Lol what the heck? Both UK and France are getting yellow flags because of terrorism. Seems absurd to me but perhaps it's good to get multiple viewpoints.

That's why I found this interesting, a variety of sources provides different viewpoints on risk. I may not personally agree, but it does help give many perspectives.

This is very common across multiple sources.

What is absurd about that?

When you drill down to active emergencies for a local area there's a ton of stuff there but it's all old. Why display it if the purpose of the site is current emergency info?

Are there any fema declared disasters you believe are omitted?

I think they are referring to the occurrence rate of false positives, not that of false negatives. E.g. the page for California lists back through to the Bond Fire, which was contained in 2020. The problem may stem from that the FEMA page lists the incident as a single day https://www.fema.gov/disaster/5385 so this tool doesn't set and end date like it would for https://www.fema.gov/disaster/5382

A similar kind of noise note could probably be made of the "Recent Earthquakes" section. E.g. if you select Indianapolis, IN it includes all the way down to a M2.6 which occurred in NW Tennessee 30 days ago.

This has been patched. Thank you.

Such a page has both dynamic and static information in it. If you don't have Internet access, that static info can still be helpful. A QR code can hold 2.9 MB of data. I'm imagining a QR code that contains the static information, and a small script that checks for connection and then redirects to the full page that also has the dynamic info. A QR code on an eink screen that gets remotely updated over LoRA could even include the dynamic info.

I appreciate the idea, but as others have mentioned it seems like for something like this to be useful it really needs to be well thought out and tolerant to extreme spikes in traffic.

I might be wrong here but it looked like the responses from the server are chunked, which I _think_ precludes the use of a highly optimized cache response e.g. from a CDN. Assuming that's true (very open to correction of course!) I wonder why this would be.

The web app has a 5-minute cache on dynamic content - which balances info freshness with performance. The architecture supports the ultra-light, fast-loading requirements by design.

This is an interesting idea, but the very first page I looked at was wrong (current weather in Alameda county shows as 72* - it's almost 30* below that here, and the daily high in the warmest areas is projected to be 65).

Next I looked at San Francisco, and oddly it listed a bunch of minor earthquakes in San Ramon - none of which are listed in Alameda county, which is actually next to (and parts of which actually felt) those tremors.

The weather API call has been fixed.

FEMA reported the earthquakes to be centred in San Ramon and not in Alameda. Will see how this can be handled.

I love this kind of thing - I'm always building lists and reference things, but IME people generally don't gravitate towards things like this.

That said, I really want a backcountry version of this. I live in Tahoe and our relationship to incoming storms (lightning) is pretty different than those in the Rockies. Plus bears and other predators (how to behave). Etc.

I once wanted to do something similar w/r/t tap water and drinkability.

Fun/neat.

What would be a good book to have in the house that could help me in as many emergencies as possible, but still be portable enough to actually bring when fleeing the house or something?

Alternatively, what would be a good bigger book for the same goal and/or be more about long term survival in case of being trapped in the house long?

Local news needs timestamps… I see stale last-week weather news. Had to click and see date from last week in the article.

Great but icons fail to render on Mosaic, Netscape and other web 1.0 browsers. Apart from that: great
