Unsung Science: The Man Who Invented QR Codes

In 1994, Masahiro Hara got tired of having to scan six or seven barcodes on every box of Toyota car-parts that zoomed past him on the assembly line. He wondered why the standard barcode from the 70s was still used...Why couldn’t someone invent a barcode that used two dimensions instead of one that could work from any angle or distance, even even if it got smudged or torn?

And so, studying a game of "Go", he dreamed up what we now know as the QR Code — the square barcode you scan with your phone. It shows up on restaurant menus, billboards, magazine ads — even tattoos and gravestones. But even that, says Hara-san, is only the beginning.

Why am I seeing posts of people I don't follow on my home timeline?


!Friendica Support
Look at this screenshot:


Now I don't follow Anubis or Katherine, and I've never followed them actually, then why are their posts showing up on my home timeline?! And as you can see from my screenshot none of my followers have reshared or replied to the posts either, so this shouldn't be here right?
I've seen their posts before too, I believe this has been happening for months now, I just didn't pay close attention before because this wasn't my main account. And I'm also using the default settings of Friendica, see this screenshot:

Any idea why this might be happening and how to fix this?

Short answer: Yes you can add Alt-Text to images on Friendica, here's how to do that - https://wiki.friendi.ca/docs/image_description

Long answer:
So in friendica they use a markup language called BBCode for their posts, everything including images, videos, etc are referenced using its syntax. You don't have to learn all the syntax yourself because there are buttons for simple things like adding images, underline, italic, bold, quote etc. Adding descriptions to images are also supported, here is info on how to do that - https://wiki.friendi.ca/docs/image_description
Unlike mastodon, Friendica also supports adding inline images to your posts, so it makes sense to write your image descriptions inside the BBCode tag for images.

I'm writing this post from my friendica account, and here's an example of image with description:

Update: OK, so it doesn't happen all the time, sometimes a mention appears like we expect - showing a username instead of the link. I think this bug only happens when 2 accounts are mentioned in a single line, will have to do more testing to confirm this though. I have attached a screenshot.

One other thing to note - it doesn't matter whether the mentions are shown correctly or not, clicking on them simply asks me to open it in a web browser instead of natively opening it inside the app itself.

One bug that I instantly noticed right now - The mentions in a post are not appearing correctly on fedilab, it just shows a link instead of the username after the @ symbol. I have attached a screenshot below.
