They also measure displacement in ICE engines. You never see a 2 Quart muscle car (I’m guessing, I have nfi what a quart is)

Skunny Kart was my favourite, mostly because it was by a group called “CopySoft”

Around here there are a variety of supermarket solutions. Morrisson’s for example near me has about a dozen cashier lines, usually 3 or so open unless there’s a rush. They have a self-checkout section like people are describing, with the small bagging area (about big enough to cage a toddler), maybe 10 of these. They also have a trolley self-checkout area, which is the same but has a bagging area big enough to cage a lioness.

M&S have cashiers, basket self-checkout, and a third scan-as-you-shop section, where you put things in your basket and scan them, and on your way out you put the scanner back and tap your phone and bag stuff, or if you’re using a trolley, just push it out to your car, whatever.

If I worked for a self-checkout manufacturing company I’d record myself saying “beep” as the beep. And “Ruh-roh” if it didn’t scan.

That’s not where it goes!

That’s incorrect.

BlueSky relies on JavaScript to run (try turning it off and loading their site, it won’t even render). Click-through traffic is almost exclusively measured by JavaScript (e.g. Google ad “events”). This is the same as measuring other stats, like whether you lingered on a post before scrolling past it, or whether you opened another tab, or whatever.

Proxy links are absolutely a method of measuring traffic, and they’re a method that works even when the site has JavaScript disabled - but since that’s not how Bsky works, it’s not relevant.
