Weird. Lived here all my life, only time I've ever heard it is in "look at those wacky Yanks" conversations. South coast/London here. Maybe it's regional?
From a UK perspective. I'm 48, most of my friends are 38-60'ish, we all call it Lego. I'm more inclined to believe that it's younger people in the UK (under 25-30) that use "Legos", simply due to the availability of US kids telly that us older farts never had (I barely had three channels up until 2002 - BBC1/2 and Channel4). My ex's kids picked up some of these aberrations ("so fun" instead of "so much fun" is an example that used to grate for me). There were so many times I wanted to sabotage that bloody Sky box.
You should check your stats some time and see how many of your users fail to load your JS, rather than are capable of loading your JS. You might be surprised, especially if you have lots of mobile traffic.
Just out of curiosity, what's the standard way to gather that data? I guess you could put a non-JS request (like an image) and a JS request (like XMLHttpRequest) on each page, and compare numbers.
My college had an (experimental?) machine they got from Acorn that dual-booted into a 'nix OS. It got stuck in a corner and forgotten about, but if it had been a few years later I think it could have been an amazing project for them.
When I was in secondary school, we had a plain grey, all-in-one keyboard and system desktop case that had a microdrive and was connected to a hacked colour TV via a massive umbilical cord. It turned out to be a BBC Micro prototype.
Schengen is for citizens only. If you are third-country national who is a permanent resident of a Schengen country, with an unlimited right to work, you have exactly ZERO right to live or work in any other Schengen country. Sure, you can travel by land without having your passport checked, but that's as far as it goes.
The European Union is a Union until you need it to behave like one, and then it isn't.
You are correct. The main pillar of the European Union is the common market including the free movement of goods, capital and people.
Schengen was originally a treaty outside of the framework of the EU but has since been taken over by it. There are EU countries outside of Schengen (GB, Ireland) and there are non-EU countries part of Schengen (e.g. Norway, Vatican, Switzerland). However all countries that join the EU now eventually have to join the Schengen area.
Besides Visa free travel for residents of these countries Schengen also includes a common Visa for foreigners traveling to these countries (so you only need one Visa to to travel to France and Germany) and allows the police to cross the border when perusing suspects and detain them on the other side.
Maybe when the market's a bit worse I'll be forced to jump through one of these hoops. But right now...
