i feel like this is a new stat to track. How many weeks until they send your movie to streaming. Will that Jeremy Allen White Bruce Springstein tie this one?

fcpguruon Ask HN: What Are You Working On? (Nov 2025)

this sounds like fear fear fear. I think you could write an article 180 degrees different from this with all the same data and just a different perspective.

nice. i was looking for this new programming language called ROFF lol

any idea why linkedin removed this? I'm hoping it was because it was just too buggy and my code is amazing hehe?

fcpguruon Auraphone: A simple app to collect people's info at events

yes! if I have a room full of androids I can use them to help spread info about ios devices that are now gone. Android helps the eco system.

why does github say "Roff 94.3%" as the main language?

fcpguruon Auraphone: A simple app to collect people's info at events

well it benefits the users if the backend never goes down!

And in this case, it can't by definition of not existing.

I think it depends a lot on the event. I would do all this at a 222.place after party if it placed me into buckets with the people I'm looking to meet.

this is good feedback. I think there are others though that are on the side of too shy didn't make that connect and leave the event with 0. And it really matters the type of event business vs. dating. If you install the 222.place app and do their questionaire you'll see the direction I'm thinking of really asking "_who_ do you want to broadast _what_ information too."

for sure, I need to start with events where the organizers can tell everyone ahead of time to have this app installed. Or I was thinking of just getting a local bar/restaurant to let me put a big auraphone sign outfront and show how that's a draw to get more customers.

Well having no backend is also a cost thing. I can scale this to millions and my fees are still just $99 a year for ios app developer program and $25 for google playstore.

And at crowded events cell towers and wifi do have problems.

Someone can send a picture of the QR code to someone not at the event. With BLE and no backend I get that 100% assurance I was actually in the room with this phone, our phones talked, and I even know how many feet away that person is in real time.

Well the idea is you are talking at event and one of you gets pulled in another direction there is no akward "hey wait I didn't get your..." you just move on and know you have that info already. The QR still requires that little action. Did you get the bluetooth working reliably in 2016? I don't mean for this to sound snarky but coding this in 2025 I kept thinking "omg without AI's help I never would have got this solid."

222 and timeleft you start in groups of 5 or 6, but then there is the "after party" with all those small groups combined. That's where this idea first came from. I was at one of those after parties and I was like wait and sec, it's 2025 why does this feel exactly like how we did this in 1980s?

fcpguruon Auraphone: A simple app to collect people's info at events

Yeah my original idea was for this to be a nightlife bar/restaurant meet people app.

and there would be gamification for free drinks/food

what if the app could guide you more on exactly who you wanted to meet. The more info you give, the better we can match with:

1. potential customers / vendors (business network event)

2. potential mates (speed dating)

3. potential friends (222.place or timeleft)

I'd keep my phone out at a 222 event if the app guided me into a group of people that all share a specific interest.

fcpguruon Auraphone: A simple app to collect people's info at events

hehe i started this way. original name of the app was "QR-Osmosis" but even that is too much friction. The idea is you are talking at event and one of you gets pulled in another direction there is no akward "hey wait I didn't get your..." you just move on and know you have that info already.

fcpguruon Auraphone: A simple app to collect people's info at events

well which specific piece, your instagram username is very different than your phone number right? And depends on the event. Is it speed-dating or tech conference? You can chose what to broadcast. If you are at the event, you have some goal of who you want to meet. Long term in the app I want to let you give more info about that and then filter the list for you. Help you find your people.

bluetooth proves you were physically there. also no cell tower or wifi issues. this app purposely has no backend! truly decentralized. If i used a normal server I would have to just trust the gps sent? And even if I could trust that, bluetooth lets me know who is closet within feet. The list of devices shows you by who is at the top, who you are nearest.

It is a chicken and egg problem for sure. Will enough people install the app and will people keep it open and in foreground often enough. I need real event with like 100 people to test :)
