101 Primer for being video-online: Part 3 - Little hints

Using Your Microsoft Surface for video-online

The Surface is a pretty superior machine in many respects but there is one thing it will not do unaided - sit perfectly vertical while you use the camera for video broadcasting.

Note the use of the word "unaided". To fix any device which has no hinge, that would be a "Surface", an "iPad" or similar, in the vertical position requires three things. And a bit of "barefoot" engineering. Frightened? Don't be.

You need a hand towel of reasonable quality. Four relatively big hardback books - all the same height. And three medium-to-large clothes-pegs. Large bulldog clips might be even better. Oh, and the fourth of the three things, is a table which is at least twice the fore and aft width of two Surfaces etc. at which you can comfortably sit.
Your hand towel should be laid from the edge of the table in front of you, preferably folded over to be reasonably thick. This is the landing area, the safety net, onto which your machine will collapse uninjured if your engineering skills prove not to be up to the job.

Then assemble the harness that will hold your computer vertical. Start with your biggest book vertical and with its spine towards you. Pull the rear cover towards you, Put another free-standing book behind and a couple of books on top.

Now clip the touchscreen computer to the rear of the first book.

Your Line to the Exchange

There are lots of bits of wire of varying age and quality between your computer and the telephone exchange where you connect to the rest of the data world. And lots of processing of your data en route to the video-online service you are using.

So what? Can you make all that work better when it's someone else's gubbins? Maybe you can.

If you are one of the 95% of Scottish households which can be connected to a fibre network, you should. Nothing else will make as much difference.

If like us, you can only be on copper cable you are (almost certainly) using ADSL 2+ technology and are probably at least 3,000 metres from your exchange. Your theoretical download speed is now a maximum of one million characters per second (8 Megabits) and that vital speed for your video being sent to others is just under 62,500 characters per second (0.5 Mbps). When you are 5,000 metres away, the speeds drop to about one fifth of that (see https://en.wikipedia.org/wiki/Asymmetric_digital_subscriber_line if you want tables and more techie stuff - masochist!).

But we are doing much better than the tables predict. Why?

This is what rain was getting into.
Quite a lot of these between us
 and the Exchange.
Our speed used to be very, very, very slow. And I noticed that it dropped dramatically when it rained. That's a clear sign of water getting into a junction somewhere on the line. The nice person from OpenReach arrived and with their trusty ladder checked successive junction boxes on the telegraph poles. They replaced two, one two poles away, the other seven. Our line speed quadrupled at once. You see how messy these are. This is ours.

If your speed is significantly less than the tables say it should be, or your Internet Service Provider says you should get, get your line inspected. Insist. Any poor physical connection on your line will hit your speed.

But first, look at how the wires in your house might be a problem.

Speeding up Your House


The wiring in your house is of dramatically lower quality than the stuff outside. That's why you plug your modem, hub, interface box (various names for the same thing) into the "master socket". That's the one your outside line comes directly to. Means you are using little of your domestic wiring.

That socket you are plugged into has probably been there a while. £10 replaced ours with a new one with two outlets. Our speed doubled. And Mr OpenReach recommended it and did it. Took two minutes. Wiring is a bit complicated for the amateur however.

Phones

Switch off the ringer on all your phones. You know why.

Reflection on Inflexions

As a mathematician, it is more or less inevitable that I count things. My spouse ticks those boxes as well. Indeed such counting is not always conscious. If you ask her at the top of a flight of stairs, how many steps there were, quick as a flash, the answer will come back. Two numbers in my life have been growing. One by modest increments, the other by a dramatic leap. The big leap is in the number of emails received, always a key indicator of constituent engagement in issues that matter to them. And with businesses, in particular, facing drop-offs in their activity because of "the bug" it is hardly surprising that contact from them has risen. The late Andy Groves was the chief executive at Intel, the company that provides the central processor in most of our computers, the "brains" of our machines. His autobiography was entitled, "Only the Paranoid Survive". I should have a copy in my library but have a suspicion that I leant it to someone. Irrit...

Junior Chef and Dish Dryer

I first engaged with the most primitive cooking when at Boy Scout camp. We threw a raw onion into the fire, removed it when well burnt, peeled the black bits of the exterior, ate the all but raw interior. Lesson learned. Cooking is a wee bit more than simply the application of heat to potentially nutritious raw material. I even managed to win the cookery award at an inter-troop camping competition a few years later. Less of an achievement than it sounds as my main rival Iain - an accomplished master of the camp oven, a tin buried under a fire - had burnt his much-anticipated bacon and egg pie. Like in Government, at home a female - my spouse - is offering guidance on how I should deal with social distancing. And just as I am listening to the wise words of the First Minister and the Chief Medical Officer, - keep your distance, don't panic buy, no pub nights - I accept without argument the idea that two nights a week are mine to cook for. Brave, brave. But help is at hand...

Unfinished ...

Yesterday was a hard day wrestling words. Or should that be wrangling? No; definitely wrestling. Because wrangling is defined as "engagement in a long, complicated dispute or argument." And that's scheduled for later today when I start my participation in the Coronavirus (Scotland) (No.2) Bill Stage 2 debates and the 55 amendments we have to dispose of between 0900 and 1400. The wrestling yesterday was trying to force words into a sensible structure for deploying in an argument. It took some time, five online meetings to be precise and a few off-the-field time-outs for tea, coffee and a couple of consultations with a dictionary. There's a rule of thumb about speechifying. Preparation takes ten times as long as delivery. And that's only about constructing the words into the right order for a decent wrangle. For some subjects, the acquisition of the background knowledge to enable you to find the right words is a lifetime's effort. I expect that I shall ...
