Now we're going to EXTEND that to 100Gb, especially for you!

This perturbs me. What does this do, over and above what Default does?
Is it to provide string searching facilities within the lost file? Which could raise privacy issues.
Hopefully it does not fire up the associated application and load the recovered file into it, which could be disastrous.
I remember Netware's Filer utility, great life-saver. Sometimes behind the scenes applications delete and rebuild files many times over though, which meant having to know which of a thousand files all with the same filename is the one that's needed.
You'd just get inside and then, without any warning, they'd suddenly close the place down for an indeterminate period.
When they did let you back in the staff would be too busy doing things like rearranging the displays to the way they were beforehand. If you did try to buy something none of the receipt printers would work.
Two possibilities that spring to mind for the Upminster fiasco. Either the linked-list that the track circuit the train is currently sitting on has a data error on its "transit time", or the train is leaving the station and has not yet caused the entry signifying its presence to be struck off the train queue. With overground signalling this can be possible - the starter signal may turn red after the last carriage has fully departed because traditionally the guard travelled in the back carriage and would check that the signalman had not flagged an emergency stop for some reason. Some old LT train describers would delete trains off the train queue in the moment when the trainstop was down (safe to go) and the signal was red: a momentary situation, but one that was often used. So why the large number of minutes? In the system designed, that might(?) represent minus one minutes, they've simply ignored the signed nature of the integer (I can imagine someone saying it's impossible to have minus one minutes, so lets's not bother checking for it). I'm pretty sure these things have moved on a lot since I worked for them (I think independent proximity detectors are often used now, which cut out a lot of cabling and relay contacts).
I'm not familiar with the signalling at Gunnersbury to say for sure, as it was not under LT control when I worked for them.
In other news "they" have fixed the problem on the Queens Park to Harrow & Wealdstone stretch of the Bakerloo line where the next southbound station after Queens Park on the Bakerloo line was announced as Elephant & Castle, whereas on the overground Kilburn High Road and South Hampstead were deemed important enough to be mentioned.
The fix now is to say, I think, "all stations to <terminus>"
My first serious programs were written in CORAL 66, running on GEC4080 series minis. Located at the Cobourg Street control centre, these were used to monitor the Northern and Victoria lines and provide train descriptions for the lines to the public via the dot matrix signs now seen everywhere.
The usual message is about evening out the gaps in the service.
The interesting one is (or used to be) Hyde Park Corner Eastbound on the Piccadilly Line, which had a thing called Balanced Headway. You'd frequently get a red signal there for quite a while and you'd get the occasional curious passenger asking the driver "why are we waiting here?" The answer was that "We're waiting for a train behind to 'drop on'." The idea was that the number of trains a certain distance behind that train must be greater than or equal to the number ahead of it in order for the train to proceed.
The shortcoming of the scheme was the limited visible counting 'horizon' the system had, it was all done using relays and long cables. With the advent of computer control it was possible to not only increase that horizon, but look at other factors too, such as trains approaching a converging junction in order to aggregate the timings.
Who remembers the Petersham Hole? We're going back to 1979 here when dinosaurs roamed the earth. Eh, no the dinosaurs came later.
No matter, you had to get off the 65 at one side of the Hole, walk around it and catch another 65 at the other side.
Tut tut. That sounds like an uncharacteristically unguarded comment from you Pascal.
Let's start again:
"What if you're a small company and can't afford [..] your own infrastructure"
Cost of a pc? Cost of a low-cost accounts package?
You need MTD? Hmm, not such a small company then, after all, but I've seen low-cost solutions that will be acceptable even for phase 2 of HMRC's rollout of MTD.
One thing is certain. The Irish are passionate about their water... (controversial I know, but one of my favourite Christy Moore songs).
When apples still grow in September when blossoms still bloom on each tree
When leaves are still green in November it’s then that our land will be free
I wander her hills and her valleys and still through my sorrow I see
A land that has never known freedom, only her rivers run free
I drink to the death of her manhood, those men who would rather have died
Than to live in the cold chains of bondage to bring back their rights were denied
Where are you now when we need you, what burns where the flame used to be?
Are you gone like the snows of last winter will only our rivers run free
How sweet is life but we’re crying how mellow the wine that were dry
How fragrant the rose but its dying how gentle the wind but it sighs
What good is youth when its ageing what joy is in eyes that can see?
There is sorrow in sunshine and flowers and only our rivers run free.

A lot of platforms have a raised section bringing the platform level up to train level (about one carriage length). This is in a designated part of the platform. (TFL call them Platform humps). I thought it would be quite easy to find a list of them and whereabouts to wait on the platform, but it looks as if this precise information doesn't seem to figure on their accessibility map, resulting in your frustration.
To work properly, the position of this raised area should be consistent throughout the whole line. So all that's needed is a list like this: Victoria Line Northbound: Travel in Carriage x from the front (carriage y from the rear); Southbound: Travel in Carriage y from the front (carriage x from the rear).
Understandably a lot of NSFW-type material comes up when searching this topic on google. It might be helpful to know that they are often referred to as Harrington Humps.
