I have a bad memory and can't memorize some important numbers, so I created this project.

I've always been concerned about being without my phone (getting robbed - which is common in Brazil - running out of battery, having it break, etc.), so I decided to create a page that sends SMS messages (LLM-summarized) and emails with more detailed information such as geolocation, IP address, and the full message.

It’s a simple page that allows sending one or more messages, with recipients being myself and other people - for example, in case I or they need help or need to communicate something important.

I don't get it. Is this for your family to message you in emergency (e.g. they lose their phones) without needing credentials to their 2FA-infested apps of sorts that they're locked out of?

Are you not getting a ton of spam from this form being open to public?

I've had similar ideas but I'd probably make it something easy to remember like myname.com/message and it quizzes the user or various things that only my family would know. Things like the color of the bedsheets, which specific IKEA kallax square the cat loves to hang out in, the location in the kitchen where the rice is stored

Yeah, I hope this is just a demo that he is showing. You usually are fine if you have a reverseDNS domain name that you don't advertise + CF, but he is now going to get spammed by genuine human traffic.

I would probably suggest switching the link to the GitHub source code and listing the actual page URL in the description; otherwise, I click the link in the article and get a location sharing request and a Send button; after a few seconds I matched that with the title, but I still had my WTF moment.

Before MFA was mandated on every service this was an easy problem to solve. Now when you lose your phone while out and about you lose your ability to log in to even Dave's Speed Cow Milker's Enthusiast Forum unless you're at home with another computer already logged in to various things.

The QR code that you use to transfer TOTP secrets to a new phone, is static. It never changes (unless you add a new service) and it requires no verification.

Do with that information what you will.

zamadatixabout 16 hours ago
If you can have a copy or deployment of your TOTP code accessible (or memorized) at any time then you've solved the same problem already!

Yubikeys could be cheaper. In addition to the two I have, I bought two more to store offsite with friends and family for redundancy (with access to my password manager + important email accounts).

When I was really bad at speeding all the time I had this fear I'd go to jail and my cat would die alone in my apt. So I started working on my own dead man switch, I actually have not finished it but I at least bought him like a self-feeding thing that would last a month or more and he unfortunately drinks out of the toilet too so I leave the top cover off.

I've recently stopped or working on stopping the triple digits driving.

The topic at hand this would be a Twilio thing sending a message like "so and so might be in jail take care of the cat" which is messed up/funny but I do tell them in advance can you be on this list. But at least this phase of my life is over/I have something to look forward to/behave for.

rsyringabout 18 hours ago
The right thing to do is stop speeding like that. Needlessly endangering others. It's good you are trying to stop. To help you continue in that effort...

Check out HPDE events to get your speed fix and keep it off public roads.

I've ran with Chin Track Days and 10/10ths and can recommend both orgs (USA based because that's what I know).

toast0about 17 hours ago
I recently purchased my mid-life crisis car; it's rear-engined, manual transmission, air-cooled, same engine block as a Porsche 914 ... but it's a VW Vanagon.

Anyway, my super sweet high performance sports car can really only get up to highway speeds, and it takes a long time to get there. Getting on the highway means at least 20 seconds of full throttle driving, and staying at highway speeds is pretty darn close to full throttle too. It's kind of fun having your foot down the whole time you're driving without endangering others. :)

One of these days, I'm going to take it to the drag strip for fun. I'll get a better value, since I'll be on the strip for at 2-3 times as long as someone in a fast car :)

Really, I got it because I thought it'd be fun to get it running and hopefully keep it running, and it would probably be an easy manual to refresh my skills and teach the kiddo and maybe the spouse on. That and bugs and cuter VW vans were spendy, so I got the Vanagon instead.

If you're paying for the track time, might as well get your money's worth!

ge96about 18 hours ago
I am past it but unless it's Nurburging track doesn't interest me although I am trying to buy a track car eg. Lotus Exige but I have time

I don't do the squeeze benz shit, if it's day time I see a gap in traffic that's when I floor it but yeah, even with a radar detector a lot of cops/troopers don't use their radar so not even helpful... and the tickets which I was dumb and paid... like I said I'm done with it as I want to stay out of jail

It's almost a curse discovering fast cars the thrill of the acceleration... I used to drive like mundane just part of life... and with the RD now I'm just on edge looking for the cops so yeah... I'm glad not speeding now

rsyringabout 18 hours ago
I agree with your almost a curse sentiment. My interest in fast cars, BMWs in my case, is a blessing and a curse. But HPDE gave me a "safe" (for others) out and I took it.

It's expensive. So, FWIW, buy a car that's really reliable and parts relatively inexpensive so you can spend your money on track time and not the car. I have an F80 M3 dual purpose car and would have got an older dedicated track car (E46 maybe) if I ever got to do it all over again.

I doubt I'll ever get to Nurburging, too far and too expensive, but I've had a lot of fun on some relatively small and simpler tracks. Turns out I like the skill needed and experience of nailing a turn more than I like raw speed on a straight.

A "simple page" but it needs multiple SaaS API keys (Openrouter, Resend, Textbelt) AND requires Temporal? I can't see how this will last/be reliable for an extended period of time.

Also, how do you prevent spam?

m0nit0rabout 4 hours ago
I really like the idea of trying to solve an existing problem.

You forget your phone but how do you access a webpage in an emergency?

If this works for you and your personal use case, then everything is fine. But I see a lot of hurdles along the way here.

I would rather think of something like: If my phone hasen't been moved over an X amount of time (locations based or accelerometer) the phone drops a note to predfined receipients with "My phone hasen't moved in 60 minutes, maybe I forgot it somewhere". You can send a location point, but that is just where the phone is.

At least it would solve the point where you have to do something manually.

delducaabout 19 hours ago
My wife doesn't check email frequently, so SMS (or even better, WhatsApp) would be more reliable.

Maybe an alternative is to store the WhatsApp contact information of people who could help behind a password.

Then, if I need help, I can ask to borrow someone's phone on the street. If they don't have WhatsApp, I can just make a regular phone call instead.

ianburrellabout 14 hours ago
Why hide emergency contact info? Put it in Emergency group on everyone's phone.

The goal should be to send a single message with nature of emergency, what you need from them, and what they do like call police

I could see a private reference page with important info. Including checklist for various scenarios. That's what I thought you did. Then print out a copy and put in binder somewhere at home.

fn-moteabout 19 hours ago
> If they don't have WhatsApp

Is this really likely? I would guess only 70 year olds don't have WhatsApp.

Seems more likely you forget the impoprtant phone numbers because you never enter them manually.

In a wider disaster, such as a fire, earthquake, tornado or hurricane both companies and families want to contact employees or loved ones to make sure that they are OK. Unfortunately, land networks, Internet, links and mobile networks may be compromised by the emergency further, people may be caught away from home. Their laptop or mobile device might run out of power.

I thought a solution might be some type of “check-in” service - especially for employees. Are you OK? How can we reach you? Are you available for work? Do you need assistance? Etc.

Things like slack, teams, etc. can fit the bill so it was not really monetizable.

Youre not alone with the problem: if device lost -> difficult to reach family

No matter what solution you choose you will need to remember something. I have two family members who always answer, so their phone numbers are the only two I know. By dialing them manually now and then I make sure my memory is working.

In the age of AI/voice generators I’ve also told them how I will identify myself. So if being mugged in Kiwiland, and they get a call where I ask them to transfer money they can do so knowing it would only be me making that request as I told them the secret phrase: ”yes, it was me who tipped over the Christmas tree”. Ofcourse not that, but something none of the inner family will ever forget.

rodolphoarrudaabout 17 hours ago
I'm also from Brazil and share the same fears. I built a family note taking app which has an internal contact form for the same purpose. One can use it to contact family members in situations of having the phone lost/robbed. Now I'm looking forward to implementing an ephemeral web conference room via API so we could have emergency voice chat. I tried with Jitsi, but it didn't work for me.

I did something similar, just a photo of handwritten phone mumbers and an easy to remember URL that's not indexed.

Anyone will hopefully lend you a phone if you're in a pinch but I realized that I don't know very numbers to actually call and it's kinda weird to start using email/Whatsapp whatever on a strangers phone compared to asking to visit one site and make one call

FractalParadigmabout 17 hours ago
> Anyone will hopefully lend you a phone if you're in a pinch

I honestly wouldn't count on it, at least not where I'm from, not anymore anyways. IME, having been in that situation (and knowing the numbers I need to call) it's rare for someone to let a stranger use their personal device for something as mundane as a phone call due to risk of theft, scams, or other criminal behaviour, not just on the part of the person borrowing the phone, but the person on the other end being contacted from an unknown number. While the chances of something like that realistically happening are incredibly low, it's a surprisingly easy social engineering method that's got people wary of trusting others to handle effectively their entire life in one device. A lot of businesses don't even let customers make personal phone calls from their landline for the same reason.

autoexecabout 19 hours ago
This isn't a terrible idea, but I'd password protect it and share the password with the people you want to be able to contact you. That'll help avoid spam/scams. "I'm your family member in trouble please send money now to X immediately no time to explain further" is a very common scam and a page like this would make it very easy.

Do you know another way to fit a 3000 long message into a 160ish SMS?
ianburrellabout 14 hours ago
Don't write long messages in an emergency. If it can't fit in one message, it probably doesn't matter. Instead of trying to predict everything, allow communication. Let them figure it out, don't command them.

Also, you might consider using existing messaging app. Then you can interact if have them install the app. Matrix might work. I think Matrix can do SMS.

It makes much more sense outside the US than to pay for a text bundle. My phone plan includes 0 SMS messages, and I don't know what was the last time when I've had to send one was. It's only useful when someone doesn't have internet, which only happens once every few months at most.
