Energy

Despite general agreement that lower energy consumption is a “good thing”, on reflection this doesn’t seem to be a real motivator. Convenience, cost, comfort; those could be the real drivers. At least, that’s my observation with respect to my own personal circumstances.

I recently switched to an all-electric car. Was this to save the planet? Was it to reduce pollution? Honestly, no. I just don’t like noisy cars, but range anxiety has kept me away from e-cars for a few years. Until now, when ranges over 400km per charge became available. Now my trips to clients, or even just down to the supermarket, are pleasurably quiet. A 200km round trip the other day was sheer delight. Fuel costs are much [click title to read more…]

Turmoil

/ˈtəːmɔɪl/ – A state of confusion, disturbance or uncertainty. A very apt word, not for the word games I was playing over the holidays, but for everything else that’s going on around us. Facing in one direction I find my British cousins, friends, co-workers, or at least neighbours, convulsed in the throes of Brexit. The consequences of this poorly formulated plan to extract the United Kingdom of Great Britain and Northern Ireland from the European Union project are vague at best and potentially disastrous at worst, and it seems that no matter what happens, roughly half of the UK citizens who express opinions on the matter will be disappointed. It’s an unhappy state of affairs, and not likely to get [click title to read more…]

Thou art more… lovely?

[ see update below ]

Some days ago the world was aghast as it witnessed online the images of “Girl with Balloon” (framed by the artist, Banksy) self-destructing as the auctioneer’s gavel slammed down. The work of art, now reborn as a performance/conceptual work entitled “Love is in the Bin”, had been encased in a frame that the artist had fashioned years in advance for exactly this purpose, according to a video release shortly after the spectacle.

The videos and images make for amazing viewing, but to my eye they ask a few questions, as yet unanswered. My questions are:

  • Why does the shredding device in the video have far more blades than strips in the shredded picture?
  • Why [click title to read more…]

Binary left shift

The logical (and arithmetic) binary left shift effectively doubles a number by moving the digits one position to the left, and inserting a zero in the least significant position. In practice the number of bits in a processor’s arithmetic register is fixed, so individual bits fall off the left side with each shift, and if you place a 1 at the least significant position then it will grow with each shift until it too falls off the left side. You can imagine this happening all at once, or just one bit at a time, though in the latter’s case you need to start the movement from the left towards the right or you’ll blitz the entire register. The rule is [click title to read more…]

Obscenities!

What follows is by way of explanation for possible observers of an annual phenomenon.

JB sat in his chair one New Year’s Eve as the minutes ticked closer to another beat of the 1980s, surrounded by family and their their “young adult” friends, already well lubricated after a few hours of merriment. If you wanted to laugh until it hurt, this was the house to be in. As distant church bells started to greet the new year, we (for this is my family and I was there) heard a commotion outside in the street, vulgar language from some people who had obviously over-lubricated.

Leaning forward and raising himself from the chair like Old Man Time himself, JB made for the [click title to read more…]
