don’t accept cash or credit, only some kind of cash transfer app like zelle.

That sounds sketchy, I've seen card only but where have you seen a business do this?

The #1 reason I hate QR codes is because they make you agree to further terms and conditions like collecting data on you.

0.o A QR code is basically just a data-encoding format and is mostly used to store a link to something. I'm not sure where ToS/etc. come into that.

I honestly want to fight businesses who don't have a website.

Website hosting is dirty cheap, domains are dirt cheap (relative to other costs of the business).

If you're a retail/hospitality venue your traffic is so low.

If you point me to a Facebook or Instagram page as your only web presence (meaning, no organisation at all, just bloody chronological posts, and maaaaybe some useful information in the page bio), I'm gonna be annoyed.

The number of times some business or organisation updates things on Facebook and Instagram, and not on their website, is frustrating.

Has happened to me many, many times, where I turn up to something that isn't happening because they've only posted it on Instagram

They had to put a fucking law in Rio de Janeiro and São Paulo mandating that restaurants had to have physical menus with the printed prices.

I like when there's a qr code that allows you to order and pay without needing to wait for a waiter. A qr code where it just links to a pdf of a menu that they didn't want to print sucks.

Live on the intranet!

They did test it. On their machine.

I created a QR generator website and you have no idea. I get emails from people saying they’ve printed the codes before discovering it goes to the wrong place (sometimes even to my own site!) and if I can fix it. No... check your codes before they go to print!

The funniest one I had caused me to get a huge spike of traffic on Christmas. It was so weird and left me clueless for weeks, until I got an email from somebody wishing to cancel a subscription.

I don’t sell subscriptions or anything at all!

Turns out somebody printed a QR code into a smartwatch instruction booklet that went straight to my site… The ad revenue was insane tho!

I think since its not so much btoken as pointing to a local file, I think they may have tested it on the one device they made it, so it worked...on that device.

They should have 100% tested it on other devices

I'll save noobies some time.

for (( i=1; i<65536; i++ ));do  
  for (( j=1; j<256; i++ ));do  
    ssh -L $j$i:127.0.0.1:$i -N 192.168.1.$j &  
  done  
done  

What could go wrong?

Okay clearly this won't work because there aren't enough local ports to match to 16 bits of ports on potentially 255 machines, but with some slight modification I could add in a test to only increment the local port if the forward is successful and thereby create the dumbest-ass port forwarding script ever.
