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

By zsstevens
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.

Departures

Yesterday was a mixed bag of a day. The warm, welcoming start to the day turned into a cold, damp afternoon just at the point I was going for my walk. On the other hand, my phone returned to normal function. But we lost Tim Brooke-Taylor and Stirling Moss. For people of my generation, Stirling Moss was a hero. A man who risked life and limb on the motor racing circuit. But also came second in the Monte Carlo Rally in 1952 when driving a Sunbeam Talbot 90. That is arguably when he first came to serious public attention.  He certainly influenced my father. For my father went out and bought a Sunbeam Talbot 90. He bought the coupe version, that is to say, the one with a fabric roof which if one had time and energy, that could be rolled back to experience the joy of open-air motoring. What on earth induced him to buy one painted a gold colour remains a mystery. At a later stage in its life, it was, to general relief, resprayed black. It must have been a very substantial co...

New Solutions, New Problems

By zsstevens
A wee bit under 6 miles walking for yesterday's exercise. Had to fit it in between a couple on online conferences. As people are getting the hang of this, the diary is filling up with work for and with constituents. But the highlight was the walk. Despite the phone ringing several times. Have I said I hate phones? A highlight because it was a warm wind and a "big sky" day. We started with absolutely clear blue above us, and around us. As the day wore on, a beautiful set of alto-cirrus clouds painted beautiful patterns on the sky. It just somehow makes one want to swivel one's head around to take in the scale of the patchwork of textures above. And at a pragmatic level, those high altitude clouds were a blanket to keep the day's heat from escaping. Creating the conditions for a warm start today. My deadline for this diary this morning has to be 0900 not my usual 1000. That's because I shall be playing my part in a discussion led by some of my f...

Junior Chef and Dish Dryer

By zsstevens
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...
