traveller's tyre travails

My summer tyres are rated Y and the winter ones are H. All manufacturer fitted. That means that the lower set is rated to 130 mph and the higher set to 186 mph. Both well in excess of the UK speed limits. Both sets are also rated for high loads, so I'd think that after one recent 60mph tyre blowout on the M25, I'd be okay for a while.

Wrong.

Another 55 mph blowout. Same side. Different wheel.

This was after they'd been checked in the workshop a week ago when I had the front one replaced. This time I was on the A69 approaching Carlisle. I could even notice that the pop was quieter than the front tyre, and I was able to pull off of the single carriageway 60 mph road into a turning.

Time for the space saver again and then back to a nearby tyre place.

These tyres all had plenty of tread, but I decided that it was time for a rashbre recall and so, probably to the delight of the service centre, I had the destroyed tyre and the other two offside tyres replaced. They showed me that the other two still looked good. Even raised the car so that I could walk underneath to look for myself.

But it's one of those piece of mind things. Instead of two more potential explosive devices along the driver side, I now have four brand new tyres, and an unplanned trip to my dealership to discuss the use of their premium MO homologised manufacturer specific tyres.

A suggestion for that missing MacBook Pro hub...

I've been travelling, and the blog has been somewhat spluttery. One of the little tasks to perform when back at base was the reboot of the MacBook Air into its new form MacBook Pro.

There's a useful bit missing from the MacBook Pro, which I will call the QacQoc. It's a sort of dongle that does everything like a Swiss Army Knife.

Three USB 3 outputs, a USB C charging input, HDMI and 1000/100/10 Ethernet, plus SDHC and SIM readers. It even includes a little storage pouch.

I deliberately got one with a 'fly lead' rather than something that plugs flush into the MBP, on the basis that I'd rather not put the equivalent of a large lever/screwdriver directly into one of the MBP ports.

So no drama as I migrate about 500 Gb from the Air to the MBP, with hardly a temperature rise on the gadget.

Although, at this rate, I may need to revisit the way I use the Cloud.

adding an extra MacBook Pro charger

There's the usual need to buy more chargers and adapters with every new computer purchase. I decided to try one of the smaller multi use devices for both laptop and gadget charging. Rated at 60w, it is one watt less than the official rating of my MacBook, although when I boot the MacBook Pro the rated wattage seems to be 45w.

Suffice to say it works fine. The little charger is quite a lot less expensive than the Apple one, especially when considering it can be used for multiple purposes. A well-known brand in America, it has all the requisite short circuit, surge, over current and temperature protection too.

This way I can flexibly have my usual three chargers. One under the sofa. One in the home office and one for on the road. Although, the sneaky thing is that the cables for USBC also need to be PD rated for power distribution or they won't work. Clever, eh? New smart cables as well as new adapters.

a few of this year's #xmasgames

The remote control for the telly hasn't featured very much over the whole festive season. Board games have certainly made a showing, including up-to-the minute topical questions from Trivial Pursuit's gambling version and a couple of vintage appearances from that game that involves uranium mining in Peru and Moon shots. That's the game where you have to balance happiness, fame and money to win according to your own secret formula.

Then there is Stockbroker, complete with its couple of specially developed extra £10 million pound banknotes because some of us get so good at the wheeler-dealering.

And, of course, there are the silly games, whether it's racing to dress one another in newspaper or clockwork snail racing. More here

Festive tidings to all.

remembering to use Boom on new macs

I'm sorting out and simplifying my various technology. I notice today's New Yorker cartoon says "Everything is charged!" - which I still consider to be an imaginary state.

A current dilemma now is how best to simplify music collections. Spotify, iTunes, Amazon, actual CDs and vinyl. I'll start with something simpler - the sound replay. For many years I've used Boom as a sound enhancer on the various Macs, but I've only recently noticed Boom 2, which I assumed was a bit of a cash-in and ignored.

Oops. Wrong. It's a very handy compressor/equaliser wth multiple presets and makes a remarkable improvement to casual listening via whatever device is to hand.

That was easy. One sound control now does everything very well and is making Regina Spektor sound perfectly wonderful.

Santa speed calculations, NORAD tracking and links to Xmas games

Time for this year's Santa Calculations, which I first published back in 2006 and then updated in 2010. This year I'm still using 7 billion as the world population because the cocktails are already at work.

Firstly, here's the link to the Santa tracking system created by NORAD.

For those of you who are more interested in the technology of Santa, NORAD's FAQs provide the following:

I've again used the Joel Potischman and Bruce Handy calculations as the basis for the speed calculations, with my own adaptations:

The most notable adjustments applied are:

- Santa delivers no gifts to naughty children (not even coal)
- Naughty to nice ratio is 1:9
- As confirmed by NORAD, one Santa distributes all of the gifts.
- There is only one family per household.
- Santa bypasses non Santa belief system houses.
- Reindeer have recently eaten fresh magic acorns.


Calculation Assumptions:

- World population = 7.06 billion
- Children under 18 = 2.353 billion (Hmm may be higher)
- Global Santa based belief systems: 33%
- Max children requiring delivery therefore 784 million
- Children per household: 3.5 (may seem high?)
- Number of households requiring distribution 224 million
- Naughty to nice factor applied but not many all naughty households
- Remove all naughty households (25% 0f 10%) = 5.6 million
- Eastern orthodox using Jan 5 instead of Dec 25 = 16 Million
- Target Households = 202 million on Dec 25
- Estimated child bed time 21:00 (9pm) with 7 hours sleep.

(child sleep duration on Dec 24 may also require revision)

Gives circa 31 hours (24+7) for all deliveries
Time is 1860 mins or 111,600 seconds

Average number of homes to visit per second = circa 1810.
So average delivery per household is 552 milliseconds, which is why Santa normally appears a bit blurry (I previously thought it was the sherry)

Land surface minus Antarctica is around 79 million square miles. Distribute destinations evenly = 0.7 miles between households creating a total distance of circa 110 million miles.

So 110 million miles in 31 hours = 3.6 million miles an hour or circa 1000 miles per second or Mach 4770 at a linear speed.

This explains Rudolph's red nose because of air resistance creating around 20 quintillion Joules of energy per second, which would convert a non reindeer nose to charcoal at such energy levels. I think the acceleration and deceleration per household may also need some examination.

Luckily Santa has lots of special powers so these mere physics facts are no problem to such a superhero.

James and the Giant Peach

We managed to get along to see James and the Giant Peach over the Christmas period, at Northern Stage. Whilst not strictly a pantomime, it still features a couple of tyrannical aunts and some crocodile tongues, and is suitably bonkers in the way of Roald Dahl.

One of the moves in child fiction is to give the young characters freedom to act and Dahl does this by killing off the parents during an unfortunate shopping expedition, when they are trampled by a rhinoceros.

This was a lavish and high energy production, delivered in the round, and we happened to have some front row seats by the stage which felt almost like being part of the action.

There were many children at the perforce, and they all seemed to know the various cues to participate in different parts of the action. suddenly, when the giant peach was floating in the sea, we were treated to about half the packed audience donning shark fin hats. I would have too, but I didn't get the memo.

Further along there were some immersive underwater scenes, with bubbles and puppetry. All of the staging worked very well. And then the cast themselves. Full of energy, encouraging the audience, most of them playing multiple instruments throughout the action packed show.

Great fun.

a loud bang

There was a loud bang as we drove around the M25.

I was already about to pull from Lane 2 into Lane 1, ready for an upcoming junction.

Yes, a high speed blowout of a front tyre. I remembered that thing about not braking but instead letting the car slow down as I indicated my way onto the hard shoulder. Also about parking diagonally with the wheels facing away from the traffic, so that I could get out of the driver door onto the hard shoulder instead of towards oncoming 70 mph traffic.

Hazard lights and all other lights on. Check for a safe place to stand behind the barrier.

I looked at the dead tyre. Behind it was a piece of wood with some nails. It may have been coincidence. High speed blowouts are usually caused by under inflation, kerbing the tyre or some catastrophic damage. I suspect the last case.

The tyre was well and truly popped. Time to call the AA and the very nice rescuer was along speedily to fix everything. Space saver tyre from the boot, torque wrench, correct inflation. And then we were back on our way at a maximum speed of 50 mph.

Later I was along at the tyre place and they read out the treads from my tyres. All six and seven millimetre, so plenty left, well above the three millimetre that I usually consider minimum.

Did I want to see the old tyre? Not really, although I'm pleased it was premium and kept me in a straight line.

shard of light

Up the Shard for a jolly celebration, before the start of the complicated logistics around the festive season.

It is always fun to look out across London, even if this occasion initially included some of the now seldom spotted London fog.

There's a fair amount of mileage involved over the next few days and I'm sure there will be plenty of twinkly lights.

2016 cycling target achieved - now for the cakes

I reckon it's safe to say that the mince pies will kick in now and I should declare my mileage target for 2016 cycling as a modest victory. 4,200 miles is respectable and hits my 'Gold' target for the year. I set 2000 miles as Bronze, 3000 Silver, 4000 Gold and *ahem* 5000 Platinum. Maybe next year?

Garmin says I've clocked 127,000 calories to achieve this.

Cakes all round before I hit reset and start all over again.

terminal velocity of snowflakes @livetheatre

I managed to get one of the nowadays rare tickets for Nina Berry's 'The Terminal Velocity of Snowflakes', performed in the Studio at the ever groovy Live Theatre.

It's a two-hander, magically performed by Dean Bone and Heather Carroll, using Nina's crisp and sparkling dialogue.

The story starts simply enough, with a glancing snowy encounter in Heaton Park, and progresses through the lives of the two characters, both separately and intertwined.

There's an underpinning idea of time's arrow and the adventure laden descent of individual of snowflakes. No wonder they all look different. It creates a simple and memorable life-lesson as the story unfolds, as well as the idea of starts, hope and the different ways that things can turn out.

That's not to say it's all warm and cuddly, there's some hard edges and audience tears as the story progresses.

As a studio sized production it is also very strong, with a stylish clean looking set design able to evoke snow, sunshine as well as the trippier moments of the narrative. Similarly the choice of music and the soundscape helps create an altogether well-rounded production.
