Jimmy Page, a living legend of rock guitar style and founder of Led Zeppelin celebrates his 70th birthday today. Wondering how it all began, with a young, shy school boy in a south London suburb, and his dream to play skiffle against his mothers advice, and to start a career in biomedical research to help fighting cancer ? Well, below there are some of his early musical performances at a BBC show that looks like the predecessor of Britain has got talent.

I am wondering if the polite interviewer from the BBC, who at this occasion was perhaps convinced that his didactic questions would bring young Jimmys on a right path of middle class academic career, ever remembered this day when in 1973 Jimmy did this:

Bad literature can be easily identified by the absence of style, or by the adoption of a very uniform style. A bad example are the Scandinavian crime stories which saw an inflation on the book discounts and the best seller lists. I guess they all follow the blood trace of the ordinary readers appetite for explicit described cruelity, for their suspicion that behind a seemingly harmonic society must be the worst degree of murder and slaughter-house sensation, and that after 5 p.m. every office clerk turns into a zombie or a werwolf, hunting for young flesh. Most of these crime novels also fuel the stereotype that moral values in the society are maintained only by a small, usually female minority.
One can do some estimations of how long will the limitted set of available MAC addresses last, until the very last one is awarded to the last Philips light bulb, of course in a big ceremony. MAC addresses are unique identifiers for devices that enable global network access. They are crucial for the increases attempts of big data collectors to unambigiously identify which computer, smartphone, tablet, or digital camera exchange information via the internet.
Each MAC address consists of 6 pairs of two hexadecimal numbers (0-9;A-F). In other words it consists of 6 byte, or 6 x 256 different strings, equally 281,474,976,710,656 possible words. This looks really like a huge number, and one might wonder if it could ever be a limitation for further growth of web. But lets just summarize how many different MAC addresses I already "consumed" since the beginning of the internet age.
At work: 5 PCs (with Ethernet cards)
4 Laptops (with Ethernet + WiFi cards)
3 ethernet/WiFi router
At home: 2 PCs (with WiFi cards)
2 Laptops with on-board WiFi + bluetooth device
1 mobile phone with bluetooth (Sony-Ericsson)
2 smarth phones with WiFi + bluetooth (HP iPaq and Samsung Galaxy)
2 handheld organizer with bluetooth (Sony Clie)
2 tablet with bluetooth and WiFi (HP Slate and Galaxy Tablet)
2 ethernet/WiFi router
3 old plug-in USB or PCMCIA WiFi sticks.
= 40 MAC addresses in total
Some of these 40 MAC addresses are already terminally out of use, together with the devices they found their way into the IT nirvana of a scrap-yard. But 24 are still in use. As compared to the > 280 trillion possible MAC addresses, this sounds msrginally. And if any other of the 11 billion people on earth would consume on average the same number of MAC addresses, 440 billions of the 281 trillions would be gone. This suggests that there is still an 500 fold excess of free MAC address available for all the future web enabled devices available, including for light bulbs, web connected fridges, kitchen ovens or electric tooth-brushes.
