Because most people sit WAY too far away from their TVs - even 720p is "retina" resolution - increasing resolution does absolutely zip because they can't even resolve the added resolution.

A rough guide is about 1:1 screen size for 1080p

Way too far away from their TVs for what? If your criterion for deciding the correct sitting distance is whether or not you can tell 720p from 1080p then perhaps you have a point, but if the object of the exercise is to watch television in comfort then 1:1 is just silly.

Thats how the internet is paid for. The sending provider pays the receiving provider for the bandwidth, and this is the only rational way it can be.

Really? I'm only an end user, but my experience is that the charging is the other way round. Traffic to me is metered (and I pay for) whilst traffic which I originate is un-metered.

Well, you could click on it for yourself (you don't have to place an order - just click the relevant radio button and then hit submit) but for those who want a short cut, the form then fails field validation with the following message.

"Sorry, for a censored internet you will have to pick a different ISP. Our services are all unfiltered."

They have low-tech means of circumventing the filter, mostly involving spending an hour going through page after page on google until they find a site not blocked.

Hardly low tech!

I too work in a school, which also implements all sorts of paranoid filtering on the school LAN. (Don't know about root CA certificates, I've never looked.)

Increasingly however, what the school does is utterly irrelevant. Almost all the students have their own completely independent access to the big bad 'net. They have phones with full Internet access, dongles for their laptops, and even laptops with SIMs built in.

It'll be a while before school authorities recognise that they're standing with their fingers in the tiny remains of a dyke, the rest of which has long since been washed away by the incoming tide. Until then, we'll still find ourselves unable to access all sorts of random and silly things in the classroom. I was refused access to the text of Rudyard Kipling's "If" the other day.

It was still an odd decision to design their own CPU for the successor to the BBC Micro. A more obvious and less risky move would have been to use a 68000 series CPU as a successor to the 6502.

IIRC, they experimented with a chip called the 32016 (or 16032) as a possible successor to the 6502, before deciding to start again from scratch and design their own.

All the 2nd processors for the Beeb - Z80, 6502, 32016 or ARM looked exactly the same from the outside, although when you opened them up the Z80 and 6502 were mostly air, whilst the ARM prototype was stuffed to the gunwales. It didn't even have go-faster stripes or a front air dam.

The odd thing was, early ARMs seemed to manage to produce much more bang for your MHz than x86 chips. An 8 MHz ARM2 ran rings around a 25 MHz 80386. What let them down then was the lack of a floating point co-processor. Later on the relationship seemed to reverse.

Just recently I've been using a NUC as my primary desktop computer. It's plenty powerful enough, and is fixed to the back of the flat screen monitor.

At first assessment you'd say it was silent, but when you switch it off you can just detect a change as the fan stops. It's not a sound you hear, but you do notice it when it goes away.

I have seen people carrying serious cash like that in the UK and the usual way seems to be as a roll of notes.

I was in Jolliffe's in Marlow (the place where all the hired dress suits come from, but they can kit you out as anything) when a chap came in and asked for a grey chauffeur's uniform. They produced one from stock, and he paid for it in cash, peeled off a large roll of notes.

Always leave room to add an explanation if it doesn't work out.
