tried tmux but realized claude/gemini/codex's --resume works great and have since started using a single chat for all small work projects

Yes, but you can't leave it running and working on something and then resume from wherever that left off that way from wherever you are.

Or are you saying you can resume a conversation that is still open in another terminal? What happens to the old terminal if you accidentally type into it? Will it overwrite the conversation?

Thanks. Decided on a CF worker to keep costs low.

so not only me! 8K passes generated since the show hn post.

Cool, so 8k stolen passes!

People have zero f'ing reasoning skills, I swear.

open-source BYOK coming right up. with your permission i'll ping you on you profile

Yeah, please do!

my use case is a loyalty barcode for a major retailer here. they provided a digital version but you had to download their app or take a picture. apple wallet is convenient, u just double tap and the Wallet loads on screen with full brightness to make it easy to scan. i dont have to keep anymore.

but on apple wallet u can't create your own a pass from a simple scan. creatign the ".pkpass" need a signature from a apple developer account.

i should've been clearer: while browsing i found multiple apps that do this. most use AI to extract data from images and are much more feature-rich - you can photo your boarding pass and it goes straight to wallet. however, i noticed that AI sometimes gets details wrong. for example, when i uploaded just a barcode image, it couldn't create the pass because the model also wanted a "name" field.

When I’ve done similar things in the past I found there was always a library for barcode/QR use cases before such things ended up being built into the OS/Framework I’m in.

https://serratus.github.io/quaggaJS/ seems browser friendly?

Generally I agree with your point on AI fuzziness here not being useful.

Millions of barcodes are scanned every second, and has been for the past few decades. So it seems very strange that there aren't any solution readily able for your app, which isn't AI.

I have to scan bar codes every once in a while with an app on my iPhone, which definitely doesn't use AI. It will instantly recognize a bar code before I've had a chance to line up the camera properly, and the error rate is zero.

https://developer.mozilla.org/en-US/docs/Web/API/Barcode_Det... Chromium browsers have native support for reading many barcode types!

Could you add Codabar?

edit: oh, I guess you can't, because Apple Wallet doesn't support it.

i think there's a way but it's hacky. instead of using the barcode property it would add an image based on your inputted codabar.

That would be pretty great. I have half a dozen codabar-based cards.

Try Pass4Wallet from the app store. It's free and supports a huge array of barcode types, including codabar. It's been my go-to custom card app for a number of years.

agree. implemented QR code scanning using the great html5-qrdecode package so scanning happens locally.

nice! don't have an android device to test - did u download it and it worked?

I wouldn't worry too much about android - you can very easily add cards manually.

I did! It worked just fine for my gym pass

not really. the .pkpass needs to be signed. you can build the file locally but you won't be able to load it in apple wallet.

Please be clearer about this on the site!

The site is pretty clear: "Free and works in browser", "Processed locally", "Private". But apparently the site (sorry for the harsh word, but I can't interpret it any other way) lies.

"is incorrect" is slightly less harsh, but in this case, I'd call it a lie. It's a rather subtle but important implementation detail. I don't think the author (who is here in this thread) is necessarily malicious because of this, but, well, it's a lie.

I'm not exactly sure how passes are signed, but in most digital signature schemes, you only sign the hash of the message, not the actual contents. Therefore you could conceivably do this in a privacy preserving way by only passing in the hash to be signed, which would allow the server to generate a valid signature without knowing the contents.

Apple Wallet passes use CMS signatures. you're right that only hashes are signed. but Apple requires an official Developer certificate ($99/year) with a private key that can't be exposed to browsers. for true privacy, each user would need their own cert. and defeats the "free" goal. and if you have a dev certificate it's trivial to generate one on your own machine.

>Apple Wallet passes use CMS signatures. you're right that only hashes are signed. but Apple requires an official Developer certificate ($99/year) with a private key that can't be exposed to browsers.

Why can't the browser send the hash to the server for signing?

let me look into it.

Any chance of allowing me to upload my own keys and doing the signing in the browser? I am sure this is a niche use case but I know how to generate the certificate for this but have been too lazy to make a thing like this for (checks to-do list) something like six years and I'd much rather just use your thing lol

that's a good idea. i'll release a BYOK version but don't plan to host it myself. will include a quick run script to run it locally.

Haha, I just made a comment above that I've been sitting on a half done project to do this for around 8 years now.

yeah was expecting that, thanks! do not use my gym pass pls
