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.

Genealogy Series: Betsy (or Elizabeth) Esplin Bell (1858-1930).

Betsy (or Elizabeth) Esplin Bell (1858-1930). She had a long criminal record driven by her addiction to drink, but was she her husband’s victim? by Stewart Stevenson. Betsy was born on 26 th January 1858 in Dundee to David Bell, a carpenter, and his wife, Agnes Sandeman. i  Father registered the birth, but is recorded as “Not Present”. George T Bisset-Smith, the Registration Examiner, published his book “Vital Registration”, the manual for Scottish Registrars in 1907. ii  In it he states that a “liberal interpretation” should be given to the word “Present” in this context but also states that “Not Present” must not be used. I suspect that leaves most genealogists, me included, little the wiser as to what “Present” was actually supposed to mean. So let’s pass on to the story. Betsy’s parents married in 1856, iii  with her mother Agnes making her mark, an ”X”, rather than signing the registration record, indicating that she was illiterate. Her husband David signed. ...

Clutter

When big things go wrong, and one feels powerless to do much about them, small things in one's life can become surrogates for one's anger. And there are quite a few big things around at the moment; COVID-19, No-Deal Brexit; A US Presidential Election where the incumbent leads with racist statements. As the end of the current session rushes towards us, many of my colleagues are concluding that they will not be putting themselves forward at the forthcoming election. A couple of our younger colleagues are placing their families first. But most are looking at being in their eighth decade, as I already am, at the end of the next session. When the two leading candidates for the US President are both older than I am - seventy-four in five week's time - it may seem surprising that retirement may be beckoning for me and others a lustrum younger than I am. But it illustrates the profound differences between being a back-bencher in our Parliament and the political life of a US Senator...

Tome for a new keybiard

Today is the one hundred and eighth daily episode of my reports from an 8th decader's lockdown. For a mathematician, 108 is a "good" number. Having three digits just locks into parts of the brain that tune into threes. And at a glance, it is a number that is divisible by three. Why, at a glance? Because if you add up the digits one, zero and eight, the answer is nine. Any number whose digits add up to a number that divides by three is itself divisible by three. If after the first add, you have answer bigger than nine, add the digits together and keep doing that until you have a single digit. This is a digit sum. If the final digit is a nine, then the original number will be divisible by three and by nine. If it's a six, then it's divisible by two and by three. And finally, if it's a three, then it is an odd number which is divisible by three. I am far from sure, but my memory is trying to persuade me that I was taught this at school. I am certain about...
