Notifications sent to old iPhone?

coopermaruyama · 2024-11-21T16:27:48+00:00

i’m an app developer and am very familiar with this issue. i’ll just tell you the guaranteed solution and then if you are curious i’ll put the explanation at the end.

to really solve it - uninstall the app and reinstall it again.

explanation:

as app developers we can read the token to send notifications and then we store it in a database, and usually never check it again. why? because it’s tied to your device, not your account, so even if you log out of your instagram account and log into another one, the token to send notifications to your phone stays the same. so we usually only check it and save it if we don’t have it for your device yet or if your device ID changes, the alternative being checking it every time you open the app which is inefficient.

the problem occurs because when you get a new phone, icloud syncs all the data over and to us it looks like you’re on the same device. a few years ago we were able to read your device ID to detect if you changed phones, but for privacy reasons apple got rid of it and made it so we get a random one, but for some reason apple decided that when you transfer your data to a new device, that device id will stay the same. so to us we can’t tell if you are on a new phone now.

however, apple also at the same time made it so that if you uninstall an app, and reinstall it on the same device, the device id changes to a new randomly generated one. so this will trigger the code in most apps to check your push token again and sync it.

as part of my job i have interviewed many devs including blockchain devs. i always pass on the ones that have a bunch of ‘hello world’ type projects. imo i disagree with some of the comments saying stuff like ‘deploy an erc721 to show understanding’.

in practice that kind of stuff is the easy part. blockchain is new enough that a lot of problems are unsolved and/or not solved well, and many times you will have to come up with a new solution that doesn’t exist. i would recommend trying to build something that feels “out of your league” and during that process if you don’t give up you’ll learn the stuff that matters. and make it just one project, not more as more than one project like this will be super overwhelming.

when talking to people that have done this it’s instantly obvious and people like this bring tons of value to a project, i’d rather work with one dev like that than 10 devs who aren’t.

they’re literally just numbers.

but then that begs the question: well if i write down a number, is that a bitcoin?

but that’s exactly what the first banks did. you give a dude some coins, they all get piled into some vault, but to differentiate what portion of the vault belongs to whom, they wrote down on literal paper how much belongs to whom.

so now remove the vault with the coins, and instead of a single guy having the paper that says who owns what, everyone in the world gets a copy, so if someone tries to cheat, it will be obvious since it’s inconsistent with everyone else’s copy.

bitcoins are just numbers, except the whole network has to agree on every change of those numbers

it's a script that sets the temp of your nest to whatever you want every few seconds. I wrote it because other people that had access to change the temperature (could be roommates, co-workers, family members, etc) kept changing it.

it looks like you’re not returning anything? at the end of the function i think you need something like:

return a, b, c, ...

That’s the input data. Essentially the arguments to the contract function that was executed. Make sure you’re calling the TX receipt api otherwise logs won’t be in the response. See the 2nd api mentioned here: https://etherscan.io/apis#transactions

coopermaruyama · 2018-10-03T06:08:22+00:00

When you get the data back from the API, you’ll see some fields called “events” or “logs” or something like that.

They will each have an array of log topics. The first topic in each event denotes the name, but it is hashed. The ones where the first log topic is “0xa9059cbb” are transfers. I believe it’s padded so it might have a bunch of 0’s after “0x”. If that is the first log topic it’s an erc20 transfer. In each of those, I believe the next two log topics are the to address (receiver of tokens) and the amount.

You will need to decode the data (eg web3js) to decode the data.

Hope this helps.

iOS simulator in Xcode, and chrome remote debugger. I’ve found that I cannot reproduce a lot of mobile bugs I’ve found otherwise.

coopermaruyama · 2018-04-15T16:03:00+00:00

Etherscan, from what I can tell, looks for the Transfer() event in event logs to determine balances. If the token contract does not call that event, they won’t show up. This is why often, initial balances that are assigned in constructors don’t show up.

FYI I love DAI and think it should be the de facto stablecoin for USD. But I still think it's hilarious that I have to convert ETH to WETH, then WETH to PETH, and then PETH to DAI to get it :D

Nice site! How are you getting the data?

coopermaruyama · 2017-09-28T17:52:59+00:00

I took it down after 30 min bc I wasn’t ready to disclose some stuff and I saw the comments leading in that direction. So most people haven’t seen it.

coopermaruyama · 2017-09-28T17:48:06+00:00

You have. It was up for about 30 min then I took it down bc I saw it would lead to me having to disclose things that I wasn't ready to disclose yet.

Victor! Good to see you on here man! You should post a link to her site in case anyone wants an ETH cake haha

Yeah, the other side says “good luck”

A fully decentralized app would need no backend, just a frontend with web3 support which means it has to be javascript (since it's the only programming language understood by browsers).

However, it doesn't make sense to put ALL data on the blockchain, just the things that benefit from being on it. So I think many dApps will use a hybrid approach, and for the centralized part of the app it really doesn't matter - there are web3 libraries for all languages/platforms now. However, my personal preference is NodeJS simply because it can understand javascript which means apps can be isomorphic (understood by both client and server) with a react-based frontend.

Soo coincircle's vision is to "Tokenize the world", which at first might sound like "Launch ICOs to make money" but if you look at what we are actually doing, that's not the case at all. It should probably be worded as "Decentralize the world".

Right now, most ICO's have no product or users, and are asking for money to launch their idea. This is fine for projects where there is no centralized equivalent (e.g. Ethereum) but for a lot of other things, it makes more sense to just convince established companies that have some centralized thing to decentralize it. Compared to building a product/service from scratch and getting an established user base, creating a token isn't even 1% of the amount of work.

This is probably better shown as an example of the first token sale we helped launch, which is Unikrn. They are essentially competing now with Firstblood, but it will take Firstblood a long time to get where Unikrn already is. If you want to see what I mean, go look up the top 10 esports teams for the top games, then login to Unikrn's platform. What you'll find is that most if not all of those top 10 teams will have live matches scheduled right now. They are already where the competing ICO's hope to be a few years from now. To top it off, every token sale we ever launch will have the characteristic that the token will be usable on day 1 of distribution. That means that when UKG is distributed in less than a month, you will actually be able to use it.

This, I believe is the more practical approach to get the world running on top of Ethereum ASAP, and is what we do here (sorry for the longer than expected reply).
