Hi I’m Tim.
I’m AuDHD - officially diagnosed ADHD and self-diagnosed (for now) with ASD. I also suffer from a great deal of Imposter Syndrome.
Most all the major distros have a way to install things outside of the project’s official repos. And this is a “people didn’t look at the PKGBUILD” issue, nothing to do with “bleeding edge” FUD.
This has been an issue with other distros in the past.
Your generic “barcode” for something like a UPC is considered a 1D barcode and uses things like the spacing of the lines and thickness to encode data. Although some 1D barcodes can detect the barcode is damaged they cannot do error recovery.
Your 2D barcodes, like QR or Data Matrix, store data in both directions and depending on format can have varying levels of error correction (duplicate data) built into the barcode. They also obviously can take up less room and hold the same or more data as well. You do need a scanner that can do 2D barcodes though, as not all scanners will read them.
They are not at all the same thing.
A QR code is just a 2D barcode that can be used to hold a certain amount of alphanumeric data (and amount is limited by size).
While pkpass is an Apple format used in its wallet app to store data.
That “article” is painful to try and read, it’s like a run on thought that bounces all over the place. The author really should make a clear outline and could probably cut out half by not saying the same thing over and over and over again. I stopped after the third time I read about Fedora flatpaks are different from flathub flatpaks, and users like flathub more, but the author is apparently eventually going to explain why that’s an issue after 2K words of nonsense.
