Here is a rudimentary alerting system I could write quickly in shell and execute on my laptop:

  while true; do echo ok | nc -l 8000; for i in 1 2 3 4; do printf '\a'; sleep 1; done; done

While the above command worked fine on macOS with the default /usr/bin/nc, on Debian 11.2, I had to modify the above command as follows to make it work:

  while true; do echo ok | nc -q 1 -l -p 8000; for i in 1 2 3 4; do printf '\a'; sleep 1; done; done

Now anytime someone connects to port 8000 of my system by any means, I will hear 4 beeps! The other party can use whatever client they have to connect to port 8000 of my system, e.g., a web browser, nc HOST 8000, curl HOST:8000, or even, ssh HOST -p 8000, irssi -c HOST -p 8000, etc.

If your port 8000 is already occupied, I recommend port 41327 as an alternative for this alerting service. After all, 41327 reads "ALERT" in leetspeak.

By the way, visit http://susam.net:8000/ right now to send me some beeps! :)

Villodre• 4 years ago

I bet you're having a fun morning with the beeps :-)

susam2• 4 years ago

Indeed I am! HN readers are a fun group. I am receiving beeps almost every second, so I updated my previous shell script to keep a record of the connections netcat receives. Also, converted the beeping loop to a background job, so that the outer netcat loop does not have to wait for the inner beeping loop to complete before handling the next connection. Notice the '&' before the last 'done' in the improved alerting service below:

  while true; do (echo ok | nc -q 1 -vlp 8000 2>&1; echo; date -u) | tee -a beeper.log; for i in 1 2 3 4; do printf '\a'; sleep 1; done & done

Here is a log of the timestamps of the connections received so far: https://gist.github.com/susam/159c7d92659b3185eb0b0d683998a3...

CraneWorm• 4 years ago

neat! here's mine:

  while true; do curl -q --http0.9  http://susam.net:8000/; sleep $(( $RANDOM % 10 )); done

wwwasdfthrone• 4 years ago

This sound like a great way to prank someone’s laptop you have access to!

i2shar• 4 years ago

On macOS you can replace printf '\a' with something nicer like 'say Lunch time!', or accept a query param and 'say $msg'

while true; do echo Coming! | nc -l 8000; for i in 1 2 3 4; do say "Lunch time!"; sleep 1; done; done

If you are on the client end of the equation and have ssh access to their mac: ssh user@host say "get your ** here right now"

samatman3• 4 years ago

Almost anything is less nice than BEL for me, since I've had terminals set to flash-on-BEL for decades.

Robin isn't going to like where this is going

berkes• 4 years ago

Brings back memories! I've had several such hacky things for my GF (now wife) and vice-versa.

`eject` + a post-it on the CD-rom tray 'Hey, look behind you!'

`ssh my-machine.local espeak 'dinner is ready'` or `ssh her-machine.home espeak "please pick up the phone! important!"`.

With a simple button exposed via a .desktop file.

charcircuit6• 4 years ago

This seems to be worse than just having your girlfriend send you a DM on Discord. Discord will make a noise and show you a notification. Discord will also show you that you have an unread message where with this it's easy to miss (what's probably a LED) flash 6 times in 5.7 seconds.

Being able to attach a message also lets you get some context on what she may need. It might not be that urgent.

hsbauauvhabzb2• 4 years ago

Building something to show her you care: priceless

hackandtrip• 4 years ago

+1.

As software engineers I think we should explore more the part of our skills that can create things that are not useful per-se, but creative and funny, such as the best gifts (at least for me) are

pikzel• 4 years ago

Yeah, forcing her to use Discord just to get his attention.

charcircuit6• 4 years ago

Pretty much everyone uses Discord now. It's not about forcing her, it's about using a chat program you use already. If you two happen to not use Discord to talk to each other surely there is some other app which you use to communicate with each other.

roel_v• 4 years ago

LOL.

GF: "Hey, can you come have a look at this shirt I bought?"

Parent: "Yeah can you please file a JIRA ticket for that, and appropriately tag its priority? I'll get notifications through my regular workflow channels and this will enable me to respond to your requests in a more timely manner! Thanks!"

Bad_CRC• 4 years ago

There is a software for running a house [1] in which you can do meal plan, etc.. (which is nice) but it has also repeating tasks like clean the windows, do the dishes and it was too Work-like for my liking.

posedge• 4 years ago

Fortunately, having discord running in the background will interrupt you another 1927329 times that day for equally important things

charcircuit6• 4 years ago

He said he was a gamer, so there is a very good chance he already has Discord open.

AussieWog932• 4 years ago

The point of this project isn't necessarily to make a useful tool but for the author to demonstrate to his girlfriend that he cares about her and is willing to stop what he's doing to listen.

b1122• 4 years ago

Which is important overall, but not important when engrossed at work unless suitable urgert.

I think that was the point of joke/parent. A GF may abuse this.

I've seen couples break up, because significant others can't understand being present, doesn't mean available.

Cthulhu_2• 4 years ago

You're already assuming that A: they use Discord, B: that while he's focused on whatever it is he's doing, he'll pay attention to Discord pings, and C: that someone asked for you to come up with alternative solutions.

jraph3• 4 years ago

Someone just moving by 1 centimeter in the corridor next to me or coughing in any bedroom (if I don't wear my headset) will do.

OH, a bird at the window!!

I'm still able to concentrate. By the way, what was I doing already? (more seriously, I can progress and I am able to get things done and recover from interruptions quite easily, but almost never focused at a point I can't notice what is going on around me. Which suits me well actually)

bryanrasmussen• 4 years ago

I have the same thing, I can easily break out of code and get right back in to where I was, I can even pretty much do it with hours break, unless things are going very badly with the code in which case I cannot handle being interrupted.

I wonder if it's my ADHD that does it actually, I can handle quick changes of attention because after all that is what I do, but if things are a problem I need all effort to not switch attention and lose what I am doing.

oh_sigh• 4 years ago

This code looks like it was written in 2004. Why aren't you using react and nodejs?

ricardobayes• 4 years ago

Simple is beautiful. Some people don't use frameworks for simple stuff. I sometimes create low-tech websites just using html+css with a minimal jquery. The speed is insane compared to usual web 2.0 sites.

fabioborellini• 4 years ago

I could make it simpler by using 1 scripting language instead of 2. There are almost as many languages as LoC there.

louissan2• 4 years ago

not sure this is a joke or not ... :-) 30MB of dependencies vs a few tens of lines of code? :-)

politelemon• 4 years ago

NodeJS is last decade; Deno is the one to go for now. But why JS based? Rust is the future, accept no substitutes. It is the perfect language for everything, forever.

jcims2• 4 years ago

Those little /ducks/ Amazon iot buttons are fun for this. I wired one up to their connect service to make a voice call. I would let my kids troll me with it or take it to work to clandestinely make calls to myself when it was advantageous to receive one.

Jaruzel• 4 years ago

I would love to see open source copies of those. Apparently they use NO power unless you press their buttons which means they can last for years.

jcims2• 4 years ago

100%. Plus they could be way cheaper (i think).

twicetwice• 4 years ago

I got some Aqara buttons and switches from cloudfree.shop, they're closed-source but local network (Zigbee) only—combined with Home Assistant, which is open source, I think this is what you want!

teekert3• 4 years ago

I use a wife alert: She Never picks up her phone, that is until I use Home Assistant to flash the lights and have the Sonos say (via HA's tts): "Pick up the Phone!". Very handy.

I know a family where the kitchen table lights turn green when their (temporarily) disabled son needs something and he is upstairs. My mom used to hit the radiator pipes with her wedding ring for that (in the opposite situation).

oefrha• 4 years ago

I have something like this for myself: a server listens for POSTs on LAN, plays a loud customizable sound on speaker, macOS pops up a persistent alert through a Shortcut, and all iOS devices receive an urgent push notification through Pushover. I can hook arbitrary high priority jobs and watchers to it since it only takes an HTTP request to activate.

Brajeshwar2• 4 years ago

This is sweet. Now, my wife uses Apple's Find My's "Play Sound" as I'm perpetually on Silent DND and I sometimes do not see her calls (she is in the whitelist and is allowed to use voice calls).

I would like to narrate a personal story from the late 80s. I grew up in a multi-family where my uncles own a lot of vehicles, including the left-handed drive Jeeps from the World War era (India uses Right-Hand Drive). Our siblings were raised by our grandmother. After she finishes cooking lunch, she always have the problem of gathering us around to eat. We would have all gone to the locality and the neighbors to play. She was always frustrated and furious about our lack of timing.

So, I repurposed a truck's horn so she can just press a switch and blow the horn loud enough for us to hear across the neighbors. I had it on the roof-top for quite a while, even after she passed away the next year. Thinking about it now, I know it was pretty reckless. It was so loud, that other families would remind their kids that -- that is the Food-Time-Horn.

foxtrottbravo• 4 years ago

We to this day have a cowbell mounted below the stairs to call everyone when dinner is ready

Loic• 4 years ago

In the French countryside where my father is coming from, every house had an external bell for the diner/lunch whatever important call. You quickly learnt to recognize the different tones and ways to ring the bell.

My parents had also the bell at the bottom of the stairs... and as a father of 3, I understand all the parents having one!

Isamu• 4 years ago

Yeah we used a cowbell- farm living.

wrp• 4 years ago

My grandmother had a kind of wall-mounted metal xylophone at the foot of the stairs to call the family for meals.

schleck8• 4 years ago

Now, my wife uses Apple's Find My's "Play Sound" as I'm perpetually on Silent DND and I sometimes do not see her calls

I had this exact problem until I scheduled my DND to automatically turn on during work hours and off afterwards. That has helped immensely

tata71• 4 years ago

It does not sound like a problem for GP.

Your recommendation, depending on apps installed, could lower their quality of life. Proceed with caution, here.

11thEarlOfMar• 4 years ago

My mom used a referee's whistle. There were 5 of us and the number of toots indicated which of the 5 she wanted (two toots for me). If we were outside playing in the neighborhood, we'd get alerted directly or indirectly from someone who was tired of hearing the whistle.

If it was dinner time and she needed us all, she'd blow 'Shave-and-a-haircut-two-bits'.

Steltek• 4 years ago

Was your Dad an Austrian naval captain by any chance?

toss1• 4 years ago

My mom used a cowbell... hadn't thought of that in years

dylan6042• 4 years ago

We had a 6" bell hung next to the back door. The same type as in churches where a rope pulls to get the bongs. It could be heard from a looooong way off. If it rang and we couldn't hear it, we were too far away from what was allowed.

metabagel2• 4 years ago

My dad whistled between his teeth. He was a prodigious whistler. As I recall, it was two tones alternating. Too bad we never measured how far away we could hear him whistling, because now I’m wondering. I’d guess half a mile though.

yread• 4 years ago

We had a metal tube/pillar supporting the top floor of our self-made summer house and a piece of metal to strike it with. You could hear that for miles!

scott_s• 4 years ago

This may be the same thing as what you call the whitelist, but in case it isn't: on iPhones, you can mark some contacts as "Emergency Bypass On." Even in silent mode, you will always hear calls and texts from them. You can also choose sounds unique to that person. I have the bypass on for my fiancee, and I chose a pleasant, unobtrusive sound for her texts. I have found this works quite well.

caioariede• 4 years ago

Oh my, this is a really great suggestion. I never heard about the emergency bypass before. I'll check it out. Thank you

Brajeshwar2• 4 years ago

This is brilliant. I was today years old learning this trick. I will still maintain a whitelist for in-laws, business partners, and others (limit of 20). However, I will add this to the core family (wife, daughters, and home).

For those looking, check this out https://www.igeeksblog.com/how-to-turn-on-emergency-bypass-o...

samatman3• 4 years ago

Something I've found is that, in particular for calls, Apple isn't able to retain object permanence around contacts.

If I assign a contact a custom ringtone, I expect all devices to know that, especially if they're going to do the insane Apple thing where every.single.device.I.own rings at the same time.

I swear Apple thinks any call which hasn't been pre-selected for voicemail has world changing importance.

wdb• 4 years ago

I got called by full name when my mother wanted me.

bigjimmyk3• 4 years ago

My mother had a heart-shaped "triangle" (about a foot across, so much larger than an orchestral triangle) that she used to call us in when dinner was ready. As a kid who did not enjoy hauling wood, my hearing was exquisitely tuned to hear that bell.

uptown• 4 years ago

My parents had huge a train bell that they'd ring.

mcv2• 4 years ago

My son always has his headphones on these days, which often makes it hard for us to reach him. I wouldn't mind being able to talk directly into his headphones.

dom96• 4 years ago

That does sound like a cool app idea.

jraph3• 4 years ago

The child might refuse to install it though.

invalidusernam3• 4 years ago

Apple watch has a Walkie-Talkie feature

f1refly• 4 years ago

For headphones to work there has to be a communication platform. I reckon it wouldn't be too hard to pick up a computer yourself, join his channel and talk to him. Wildly depends on your sons age though, I guess I wouldn't have been too keen on my mum having access to my teamspeak when I was 15.

mcv2• 4 years ago

I don't need to hear who he's talking to. I just want an interrupt button to say it's dinnertime, or something like that.

It somehow bothers me that the TLDR is much longer than the actual text, but nice little tool anyway.

300bps• 4 years ago

Not only is the TLDR longer than the actual text, it repeats it almost verbatim before adding additional information.

baxtr• 4 years ago

I am glad we found something to complain about on this post. Good job!

smoyer• 4 years ago

If it dings occasionally, it means your girlfriend is trying to reach you. If it dings continuously, it means she's breaking up with you.

Yes, I'm trying to be a little funny but the point is that (outside perhaps work?), you should probably be a bit more engaged with the people that mean something to you.

azeirah2• 4 years ago

I really wouldn't assume too much about his situation.

My girlfriend has autism and when I want her attention I need to ask for it like 5 times over a space of 20 seconds, if I don't ask multiple times she will literally forget I even asked in the first place. Sometimes it literally takes a minute. This isn't because she doesn't care about me, it's just how her brain works.

Maybe this is just a better form of communication for him while he's focused on work. Please don't assume ill-intent, it just seems unnecessarily rude.

beefield• 4 years ago

Out of curiosity, how does your girlfriend react if you just start talking to her without asking attention? (Reason I ask, occasionally I think I might be on the spectrum, and my SO has a habit of just starting to talk to me. Most of the time I miss the beginning, which annoys to no end my SO...)

teekert3• 4 years ago

I'm very happy that the people I care about don't require me to engage with them constantly. Engaging with them in chats are not the right type of engagement if you ask me. Maybe I'm old.

kayodelycaon2• 4 years ago

Or… people who require constant engagement go elsewhere because you’d not giving them constant engagement. ;)

kayodelycaon2• 4 years ago

you should probably be a bit more engaged with the people that mean something to you

If someone is neurotypical and fully functional... maybe? For someone who isn't, this is basically "try harder to be normal", with all of the guilt and judgement that implies.

For example: Telling a person with chronic clinical depression they have no reason to be depressed and are being ungrateful for having a successful career.

When I don't answer my wife just calls me through the Alexa which is the creepiest ring ever. The sound is so foreign and my hackles rise whenever Alexa does anything on its own so it gets my attention instantly.

I need to teach my German Shepherd how to use curl so she can also use this method.

glenneroo2• 4 years ago

The run.py script indicates this is running on a Raspberry Pi to read GPIO pins i.e. you could literally just hook up a button to a GPIO pin and train your dog to stomp on the button.

whalesalad5• 4 years ago

It was meant purely as a joke. Even if I built the most elaborate notification system in the world - she basically runs the show. I did a doggy version of 23andme, she is 30% Siberian Husky and 6% Belgian Malinois so the line is blurred between sweet loving companion and psychotic girlfriend.

hokumguru• 4 years ago

GSD owner here, but her and all of our dogs in the past we've taught to ring a bell hanging from the back door whenever they need to go outside. Great alternative if you don't need/want a dog door.

joshschreuder• 4 years ago

It’s super easy to teach too!

We also have voice recorder buttons they can use to ask for certain things like brushes, treats, play time etc. but those get much more annoying :)

Are people seriously this tied in to their computers? I'd hate to see myself get to the point where I don't have time for women and need to be beeped in order to pay attention.

whalesalad5• 4 years ago

Are you familiar with the concept of deep work? Sometimes you need a solid block of completely uninterrupted time to keep your cache/working memory hot so that you can see the whole task through. My wife used to interrupt me all the time - even in the middle of a wim hof breath hold. I'm looking at her like, this is the 10,000th time I have done this, and we do it together sometimes, why do you think I can respond to you in this moment?

diogenesjunior2• 4 years ago

I work for a large tech company 10-12 hours a day + 2-4 hours at home and I could never see my girlfriend needing a SOS light to get my attention.

BurningPenguin2• 4 years ago

Doesn't mean he's completely tied to it. He may be only focused on his hobby. That can happen with anything. Woodworking, drawing, reading, whatever. Being on constant alert isn't healthy. Everyone needs some time for themselves to power down a bit.

joshmanders• 4 years ago

Or maybe people just want to have something special for their loved ones to help THEM feel special to them.

I had considered making something for my girlfriend also, because she loves that I'm a nerd and I wanted to use my nerdiness to make her something special, even if it is just a button for her to press that lights up a light on my desk, just so she can tell me she's thinking of me.

cgufus• 4 years ago

Many many years ago I played a browser-based online game and I used curl and php for scripting the game. I eventually programmed an alert feature that woke me up (OS X: ‘say “Warning you are under attack”’) during the night when I was being attacked.

good old times :)

Someone1234• 4 years ago

Apple Watches have a cool Walkie-Talkie concept that could have worked well for this scenario.

I call it a concept though because the app as-implemented is unreliable and gets stuck in "Checking availability," "Trying to reconnect" every time you launch it. If you lower your wrist while it is trying to reconnect the app gets suspended and starts again.

So imagine standing there for sometimes up to a minute with your wrist extended while the Walkie-Talkie app tries to reconnect, all to hypothetically save time. It isn't workable. Which is a real shame because great concept on paper.

britches11• 4 years ago

It's also a major battery drain -- probably thanks to the issues you mentioned.

mikestew• 4 years ago

It's a feature used once and then disabled. It seemed cool back when we got our Watch 4s, but as pointed out, it seemed like someone's side project that somehow made it into production. Turns out, you could have just called in less time.

BeefWellington• 4 years ago

Back in the mid-2000s or so before 2FA was really a thing, I built a small perl script to have my server do audio beeps using the PC speaker based on some activity in the system. The idea was I sat in my office near enough to my servers at home that I could hear audio beeps. I also had patterns of sounds so that each type of activity was a different noise, e.g.: SSH logins would produce one pattern, local login a different set, etc.

I've long since lost the script but I've seen a few similar ideas kicking around over the years. Really only applicable to homelabbers I imagine and probably easy enough to throw together again.

lillesvin2• 4 years ago

Remember the dude whose garage port opened and closed seemingly at random because his /toggle endpoint ended up in his browser's "most visited" list: https://news.ycombinator.com/item?id=16964907 ?

I have a feeling the same thing could happen here.

dokem• 4 years ago

That's why you have to use a POST request. GET should be read-only and a browser will not re-issue a POST for things like most-visited, tab restore, pre-fetch, etc.

lillesvin2• 4 years ago

Yeah, that's what the guy in the linked post is talking about. Various services (Skype/Teams, Slack, Twitter, etc.) will also send a GET if the URL is shared there. I once saw an accidental hotel booking triggered by Skype because the booking was performed through a GET request with a brazillion parameters.

I get the living day lights scared out of me at least twice a day (by my gf) while working with headphones on. Light is perfect.

unexistential2• 4 years ago

I built something similar for my girlfriend's birthday a few months ago. A buzzer and a lightbulb connected through a relay to an RPi, which hosts a basic HTTP server. The server is exposed to the Internet through a reverse ssh tunnel to a VPS in the cloud.

What has taken me aback is how it regularly receives malicious traffic that I suspect is from bots scanning for vulnerable servers. The hostname is not shared anywhere public. The client app that knows the URL has only been shared to her as an APK. Made me realize there's no such thing as security through obscurity.

jayshua• 4 years ago

I wonder if having only an IPv6 address would provide enough obscurity to be reasonably secure in this case? Or maybe those allocations are still to publicly guessable?

asveikau• 4 years ago

You're saying the malicious requests are hitting the obscure path that only shows up in her apk?

Is it running https? Trying to think of how they would have gotten that, eavesdropping would be one way.

Otoh if they are hitting your host by randomly probed IP address but don't know the obscure path, that is not surprising at all. There are tons of exposed http ports unknown to their operators, and it is makes total sense that bad actors are trying to discover them.

unexistential2• 4 years ago

No, thankfully they're hitting paths like /phpmyadmin/index.html which do not exist on the server. Makes sense, it's probably random IP address based probes long you said.

I'm not running https but I should, to protect myself from someone MITMing the requests and possibly pwning my Pi.

NaturalPhallacy• 4 years ago

This reminded me of the function I added to my .bash_profile that would randomly tell me to buy flowers for my girlfriend for a while.

        # flowers?

            echo -en "\nI should"; if [[ ${flowers} != 0 ]]; then echo -n " not";fi;echo -e " buy flowers today.\n\n"

A former coworker has a wife alert. When her phone connects to the WiFi, the light at his desk turns red.

He mumbled something about needing to close a bunch of tabs featuring pink pixels.

JetAlone• 4 years ago

The tabs must be shopping websites, he's been looking for a secret present for her.

akanello• 4 years ago

This is fun.

I made a similar thing with an rpi(sans the sound), when my girlfriend had mild covid and was isolating in the room next door.

It's was nice to have an electronic communication method bespoke for her (even if it doesn't communicate that much information).

sexy_panda• 4 years ago

As you're already using python for gpios, you could just use flask to get rid of php. This will shrink your dependencies by at least 100MB.
