Show HN: Safe-now.live – Ultra-light emergency info site (<10KB)

195 points by tinuviel 8mo ago

After reading "During Helene, I Just Wanted a Plain Text Website" on Sparkbox (https://news.ycombinator.com/item?id=46494734 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. https://safe-now.live https://safe-now.live

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

  I've added them. Thank you.
jonathanstrange 8mo ago
Looks nice & useful. However, I'd make two versions: The one you have, and additionally a version with Javascript that is a Progressive Web App (PWA). I'm pretty sure some AI could convert the normal page into a PWA for you. The PWA has the advantage that it will also load when the internet is down and there is no need to save the page manually.
- yearolinuxdsktp 8mo ago
  How can it load when the internet is down?!? Doesn’t the PWA source have to be fetched? And if it’s cached, then so can be the static resources.
  - jonathanstrange 8mo ago
    The complete web page and all resources are saved locally by the service worker. "Clear site data"/clear cookies will delete it. However, clearing the normal browser cache won't. It's overall a little more persistent than the cache for static resources. However, it needs to be installed as an app to really work offline without initial loading. Chrome will prompt you for that on Android, Linux, and Windows. Safari can also do that but makes you jump through hoops. In Firefox, the PWA will work like a page that loads even when the machine is offline.
- rjh29 8mo ago
  That sounds unreliable as cache can disappear. A regular mobile app would be safer.

I would suggest increasing font-size, looks too small
- austinjp 8mo ago
  Yup. Even on mobile the text is too small for me. In particular, the line-height could be larger so links can be tapped more easily. Nice though, I like it.
- Brajeshwar 8mo ago
  I think the default target is expecting a smaller screen mobile device, hence the 13px default. This is a good idea, and any other screen sizes that see smaller text can still zoom in using default browser behaviors.
- duskdozer 8mo ago
  Agree, even just converting to use em instead of px is more usable on differing screen size/dpi
- torgoguys 8mo ago
  I disagree. When I saw the page, I thought, "Finally an information dense page again! It's been so long since they've been common and I miss them."

    I disagree with your disagreement, for example HN is readable but the linked site feels too small for my eyes on a 21.5" 1080p monitor. It also doesn't respect browser preferences, unless you enforce a minimum font size (which can break display elements on other sites): font-family: Calibri, Candara, Segoe UI, Optima, Arial, sans-serif; font-size: 13px; If the dev wanted a similar effect by default but be more accommodating, they could do: font-family: Calibri, Candara, Segoe UI, Optima, Arial, sans-serif; font-size: 0.8125rem; There's no reason why you couldn't have smaller font while still respecting browser scaling. However, they might also want to just leave it at 1 rem and let the folks that prefer higher information density to customize their own browser settings, since those are what most well developed sites should respect and it might be more accessible by default on most devices (for my eyes, at the very least). As for targeting specific screen sizes for non-standard font scaling, media queries also would help! In regards to missing information dense pages, try changing your browser font settings, it might actually be quite pleasant for you to see many sites respecting that preference!

It must be able to cache it's all content in browser. I guess to do it it properly you need to make it PWA.
- Croak 8mo ago
  You can also just use proper HTTP cache headers. ETag and a very long Expires header.
- tinuviel 8mo ago
  Idea is to keep it light and accessible. PWA would be data heavy. The use case is in the article linked in the post description.

  - zamadatix 8mo ago
    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 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 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.

The font size is too small for emergencies on mobile devices. You need to consider that users might be in a panic, may not have both hands free to zoom in, and their vision could be impaired by smoke or other factors.

  It is astonishing how one's motor skills degrade when the adrenaline is flowing. I once tried to dial 911 on an iPhone in such circumstances. My hands were shaking so badly I kept dialing 922, 811, 914, and so on. Terrible in the moment but a very good lesson for preparedness. I really appreciate the "dial Emergency" methods on modern phone software that just need a button held down.
  - 8cvor6j844qw_d6 8mo ago
    My only complaint with hold-to-dial emergency dialing is phones with damaged or glitchy buttons (ghost presses) that trigger it accidentally. There's probably a setting to disable it, though I think its manufacturer-dependent.

>Flood: Higher ground - Turn around, don't drown It's hard to take a 14 year old serious ...
- drob518 8mo ago
  In Texas we lose people every year because they think they can make it across what looks like a small, shallow creek and are swept away by water that is really much deeper. You might think, “Well, those are stupid Texans,” but we even have EMS personnel die that way. A couple years ago we lost a deputy sheriff who was patrolling and trying to monitor water levels. Her car got swept away and then pinned downstream and she drowned. “Turn around, don’t drown,” is a mantra here.
davedx 8mo ago
The UK emergency phone number is 999, not 112. Ugh. Don't make a website like this without verifying the information is correct please!
- tinuviel 8mo ago
  https://www.gov.uk/guidance/999-and-112-the-uks-national-emergency-numbers https://www.gov.uk/guidance/999-and-112-the-uks-national-eme... 112 is also a national emergency number.
- deceptionatd 8mo ago
  112 and 911 (US) work on almost every mobile phone anywhere in the world. It's part of the GSM/UMTS standard. 999 is supported with either no SIM card or a UK SIM card. See §7.1 here: https://www.ietf.org/lib/dt/documents/LIAISON/file562.pdf https://www.ietf.org/lib/dt/documents/LIAISON/file562.pdf They also don't require a phone to be activated in most countries. I believe there are some exceptions in EU countries, but in the US it just needs to have a working antenna and be in range of a tower.
goda90 8mo ago
It would be good for the specific state/province/city pages to include the same info from the ancestor pages so you only have to link to and load one page for your area.
hypeatei 8mo ago
It appears the site couldn't handle HN traffic or maybe the site owner took it down. Regardless, a project like this needs a lot of thought put into it to be something that people can rely on during times of crisis. If it can't handle a surge in traffic from HN, it won't be able to handle a surge during natural disasters.

    Something working after a spike doesn't tell you much anything about how it did during the spike. At best, it's a hint that maybe the server did not physically burn to the ground, but even that is not for certain.
- tinuviel 8mo ago
  The site is light enough to handle traffic spikes from HN. The site was being patched based on feedback here. You should see it up and running.
goda90 8mo ago
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.
hobo_in_library 8mo ago
Seeing how it hasn't survived the HN hug of death... Not sure how you've built it but consider putting it behind a CDN or something and caching the responses, esp since you're trying to pull live data
- tinuviel 8mo ago
  It was never down - it was being patched and redeployed based on feedback here. Webapp is light enough to handle 10000 concurrent hits.
  - deceptionatd 8mo ago
    I can't tell much about your infrastructure, but memcached would probably increase that by several orders of magnitude. The NGINX module is pretty simple: https://nginx.org/en/docs/http/ngx_http_memcached_module.html https://nginx.org/en/docs/http/ngx_http_memcached_module.htm... Cloudflare with Cache-Control headers is even simpler if you're okay with adding Cloudflare as a dependency. From an ASN lookup, it appears you're hosting on Oracle Cloud, so Cloudflare would also give you free data egress: https://blogs.oracle.com/cloud-infrastructure/why-cdn-clients-migrate-cloudflare-oci https://blogs.oracle.com/cloud-infrastructure/why-cdn-client... Their Always-On feature would also help if Oracle has an outage. I like the general idea, very lightweight and more likely to remain accessible when an emergency is overloading the mobile networks.
    - tinuviel 8mo ago
      Thank you! I will implement this - the server code is in plain C with NGINX on top so I presume adding memached would be straightforward.
shoelessone 8mo ago
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.
- tinuviel 8mo ago
  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.
happyopossum 8mo ago
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.
- tinuviel 8mo ago
  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.

You need an AI angle if you want investment and up-boats. Suggest a LLM-based chat that consumes feeds and provides a terrification-score rating letting you know how to calibrate your panic-levels, based on real data. Allow for real-time questions on how to purify water, if it's better to carry gold or ammo etc Good luck. I'll give you 80 mil based on a 40% stake with voting rights.
browningstreet 8mo ago
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.
ohashi 8mo ago
I've been working on a similar idea for travelers, https://travelsafetydata.com/ 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!

From an accessibility perspective, the HTML emoji might be an issue for screen readers. You can still keep them as `h2#foo::before{content: "emoji ";}` CSS pseudo-elements instead, if memory serves. (Used "emoji" as a placeholder to ensure it renders in the example.) Great project; (way) more websites should look like this.

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?

My gut feeling is that I'd want it to use my IP address to get as much relevant data as possible. I don't want to click into my state, then city/county. As others pointed out the font is a bit small so clicking on states is pretty tricky.

LandenLove 8mo ago
I see that you mentioned no images, but I feel that images would make it easier for quickly locating information. You can probably use some basic svg files to keep the file size small. E.g. a simple design of a building shaking to represent an earthquake. Right now, I am seeing a flood of text that I have to carefully read. I don't think emoji's would help, because they can be more subject to interpretation. And the quality of the design varies based on the device's emoji font. But it is an interesting concept. Maybe add a small note about bookmarking the page?
- tinuviel 8mo ago
  Thank you. Images would increase the page size. Intent is to keep this accessible on slow/overloaded connections.
  - ashenke 8mo ago
    I think what he is saying is adding simple svg icons, not images. For instance this one https://www.svgrepo.com/svg/308550/earthquake-damage-earthquake-property-damage https://www.svgrepo.com/svg/308550/earthquake-damage-earthqu... is 700 bytes, and it can most likely be simplified and compressed. (you can also lazy load them so they don't delay the content)

Shows the Nash Ranch fire as an active emergency but it was declared in 2008. [0]: https://safe-now.live/c/us/co/colorado-springs/ https://safe-now.live/c/us/co/colorado-springs/

>Flood: Higher ground - Turn around, don't drown It's hard to take a 14 year old serious ...

drob518 8mo ago
In Texas we lose people every year because they think they can make it across what looks like a small, shallow creek and are swept away by water that is really much deeper. You might think, “Well, those are stupid Texans,” but we even have EMS personnel die that way. A couple years ago we lost a deputy sheriff who was patrolling and trying to monitor water levels. Her car got swept away and then pinned downstream and she drowned. “Turn around, don’t drown,” is a mantra here.

The UK emergency phone number is 999, not 112. Ugh. Don't make a website like this without verifying the information is correct please!

tinuviel 8mo ago
https://www.gov.uk/guidance/999-and-112-the-uks-national-emergency-numbers https://www.gov.uk/guidance/999-and-112-the-uks-national-eme... 112 is also a national emergency number.
deceptionatd 8mo ago
112 and 911 (US) work on almost every mobile phone anywhere in the world. It's part of the GSM/UMTS standard. 999 is supported with either no SIM card or a UK SIM card. See §7.1 here: https://www.ietf.org/lib/dt/documents/LIAISON/file562.pdf https://www.ietf.org/lib/dt/documents/LIAISON/file562.pdf They also don't require a phone to be activated in most countries. I believe there are some exceptions in EU countries, but in the US it just needs to have a working antenna and be in range of a tower.

It would be good for the specific state/province/city pages to include the same info from the ancestor pages so you only have to link to and load one page for your area.

hypeatei 8mo ago

It appears the site couldn't handle HN traffic or maybe the site owner took it down. Regardless, a project like this needs a lot of thought put into it to be something that people can rely on during times of crisis. If it can't handle a surge in traffic from HN, it won't be able to handle a surge during natural disasters.

Works for me 10 minutes after your post. I'm happy to be part of the unintended load test.
Imustaskforhelp 8mo ago
It's working for me after 16 minutes of your comment & someone else mentions how it works after 10 minutes of your comment.

  Something working after a spike doesn't tell you much anything about how it did during the spike. At best, it's a hint that maybe the server did not physically burn to the ground, but even that is not for certain.
tinuviel 8mo ago
The site is light enough to handle traffic spikes from HN. The site was being patched based on feedback here. You should see it up and running.

goda90 8mo ago

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.

hobo_in_library 8mo ago

Seeing how it hasn't survived the HN hug of death... Not sure how you've built it but consider putting it behind a CDN or something and caching the responses, esp since you're trying to pull live data

tinuviel 8mo ago
It was never down - it was being patched and redeployed based on feedback here. Webapp is light enough to handle 10000 concurrent hits.
- deceptionatd 8mo ago
  I can't tell much about your infrastructure, but memcached would probably increase that by several orders of magnitude. The NGINX module is pretty simple: https://nginx.org/en/docs/http/ngx_http_memcached_module.html https://nginx.org/en/docs/http/ngx_http_memcached_module.htm... Cloudflare with Cache-Control headers is even simpler if you're okay with adding Cloudflare as a dependency. From an ASN lookup, it appears you're hosting on Oracle Cloud, so Cloudflare would also give you free data egress: https://blogs.oracle.com/cloud-infrastructure/why-cdn-clients-migrate-cloudflare-oci https://blogs.oracle.com/cloud-infrastructure/why-cdn-client... Their Always-On feature would also help if Oracle has an outage. I like the general idea, very lightweight and more likely to remain accessible when an emergency is overloading the mobile networks.
  - tinuviel 8mo ago
    Thank you! I will implement this - the server code is in plain C with NGINX on top so I presume adding memached would be straightforward.

shoelessone 8mo ago

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.

tinuviel 8mo ago
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.

happyopossum 8mo ago

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.

tinuviel 8mo ago
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.

mattlondon 8mo ago

You need an AI angle if you want investment and up-boats. Suggest a LLM-based chat that consumes feeds and provides a terrification-score rating letting you know how to calibrate your panic-levels, based on real data. Allow for real-time questions on how to purify water, if it's better to carry gold or ammo etc Good luck. I'll give you 80 mil based on a 40% stake with voting rights.

browningstreet 8mo ago

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.

ohashi 8mo ago

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

rjh29 8mo ago
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.
- 936966931646863 8mo ago
  What is absurd about that?
- nicbou 8mo ago
  This is very common across multiple sources.
- ohashi 8mo ago
  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.

https://travelsafetydata.com/country/SE https://travelsafetydata.com/country/SE 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 https://travelsafetydata.com/country/NO It lists child protection laws as "scams & fraud"

This is really useful! I'm planning on making a list of websites that work well with Lynx and other text based browser, specifically because people should be able to access important information regardless of how powerful their computer is

From an accessibility perspective, the HTML emoji might be an issue for screen readers. You can still keep them as `h2#foo::before{content: "emoji ";}` CSS pseudo-elements instead, if memory serves. (Used "emoji" as a placeholder to ensure it renders in the example.) Great project; (way) more websites should look like this.

dprice1 8mo ago

I like this! I noticed that the weather for some Bay Area counties seem to be getting zeroed out for temperature. https://safe-now.live/c/us/ca/county/san-mateo/ https://safe-now.live/c/us/ca/county/san-mateo/ https://safe-now.live/c/us/ca/county/santa-cruz/ https://safe-now.live/c/us/ca/county/santa-cruz/ (both say: Weather Now 32°F / 0°C - Sunny )

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

This is an excellent idea, ill pass it along to friends in emergency management

tinuviel 8mo ago
Thanks! Could you gather feedback after you do, please?

mosselman 8mo ago

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?

Neywiny 8mo ago

My gut feeling is that I'd want it to use my IP address to get as much relevant data as possible. I don't want to click into my state, then city/county. As others pointed out the font is a bit small so clicking on states is pretty tricky.

cachvico 8mo ago

Floods - remove "Don't drown" and add "Stay out of the attic". Plenty have died trying to seek shelter in an attic.

I really appreciate lightweight software, including websites. I don't need them, but I really, really like them. they have a certain feeling that I can't describe, but it's great.

LandenLove 8mo ago

I see that you mentioned no images, but I feel that images would make it easier for quickly locating information. You can probably use some basic svg files to keep the file size small. E.g. a simple design of a building shaking to represent an earthquake. Right now, I am seeing a flood of text that I have to carefully read. I don't think emoji's would help, because they can be more subject to interpretation. And the quality of the design varies based on the device's emoji font. But it is an interesting concept. Maybe add a small note about bookmarking the page?

tinuviel 8mo ago
Thank you. Images would increase the page size. Intent is to keep this accessible on slow/overloaded connections.
- ashenke 8mo ago
  I think what he is saying is adding simple svg icons, not images. For instance this one https://www.svgrepo.com/svg/308550/earthquake-damage-earthquake-property-damage https://www.svgrepo.com/svg/308550/earthquake-damage-earthqu... is 700 bytes, and it can most likely be simplified and compressed. (you can also lazy load them so they don't delay the content)

lasgawe 8mo ago

One of the most unique ideas I've seen. Good to see this is just a 4.4 KB HTML page and does exactly what it says.
