What you do, of course, is scramble over the mound of rubble, picking your precarious way until you can go no further, leap across the trench grabbing the red boom to stop yourself slipping back and into the hole, then squeeze out between the red and the white booms to the relative safety of the road beyond. You do this on average three times a day if you're a Doha walker. You do it in Musheireb, in Muntazah, in Mansoura. You do it because the alternative is usually to retrace your steps for up to a hundred metres and walk round the outside of the barriers, cheek by jowl with the crazy traffic. You do it because, second only to demolition, Qatar's national pastime is digging up the roads and pavements. And unlike most other cities, in Doha they generally make no provision for alternative walkways, probably because if you are insignificant enough not to be driving a Land Cruiser you don't really merit 'normal' consideration.
My caption, "Well, If you knows of a better 'ole, go to it" in case you were wondering, was first used by the World War One cartoonist Captain Bruce Bairnsfather. If you've not come across his work, check it out. Nearly a hundred years on, we're still blowing ourselves to bits. Only the weapons change. The inhumanity is constant.
This song by Harry Gordon is about 100 years old and is in the Scottish music hall tradition. It's short because it was the lead into a stand-up comedy routine in character. The character in this case being a fireman on the footplate of a steam engine.
The triode was invented in 1906 by Lee De Forest and by around 1920 was refined enough to be commercially viable for widespread distribution. It was the World's first 'Active Device'. It could amplify and oscillate. It (and its derivatives) made possible all of the technologies of modernity – public address, radio, audio/video recording, television, radar, radio telescopy, electron microscopy, computing, the Internet, artificial intelligence. Without active devices, modernity would vanish in a flash. Those who really want to turn the clock back need only abandon science, technology and education. Nature will do the rest.
