The Sun sez

Posted by Polonius on 10 October, 2006

Of course the Sun is a squalid little rag that gives a bad name to British democracy, but once in a while I have to grudgingly concede that its headline-writer has scored a blinder. Who can forget “Super Caley go ballistic, Celtic are atrocious”? This morning is another of those occasions, with “How do you solve a problem like Korea?” It knocks the Daily Record‘s “Bam with the bomb” into a cocked hat.

BBC News continues downhill (2)

Posted by Polonius on 9 October, 2006

Just spotted a remarkable piece of reporting by the BBC. See the headline? The photograph? The caption? Tabloid spin or gross incompetence?

Update: They’ve fixed it. The story concerned two youths who had been charged with arson. A  17-year-old, who because of his age was entitled to anonymity, had been found guilty, as trumpeted by the headline, “Youth guilty of £8m school arson”. Immediately below the headline was a photograph of the other accused, who, at 18, was not entitled to anonymity. The small caption under the photograph gave his name and mentioned that he had been cleared, contrary to the impression that any reasonable person might infer from the proximity of the headline to the photo.

Just a cockup.

Single point of failure

Posted by Polonius on 5 October, 2006

Yesterday’s edition of The Daily WTF told a tale of some HVAC maintainers who managed to close down a bank’s wire transfer capability by taking down both air conditioners for preventive (sic) maintenance. It seems slightly implausible, because hardware is usually significantly more tolerant of high temperatures than wetware, but never underestimate the stupidity of HVAC maintainers. I remember, many years ago, two people staggering out of a computer room with splitting headaches after a trained monkey had left a hose flapping about while doing some maintenance. Apparently the people in the room hadn’t acquired the knack of living on an atmosphere consisting largely of freon.

But I digress. One of the bank’s major errors was of course having a Single Point Of Failure (SPOF). For all their redundant systems, the servers were still all in one room. It is bizarre that many of the UK’s ISPs have their main server farms in one building, at Telehouse Docklands. I hope the ISPs have mirrored facilities on other sites. I’m sure Telehouse has no end of redundant electrical supplies, UPSes, generators, inert gas extinguishers, etc., etc., but it’s still one building.

You can design systems to withstand all predictable failure modes, but if you have a SPOF, you can be confident that an event, or combination of events, that you didn’t predict will catch you unawares, and nobody knows that better than Telehouse themselves. In September 2001, it is claimed that 70% of all Internet traffic between the US and Europe passed through Telehouse’s premises at 25 Broadway. When the World Trade Center collapsed, it took out Telehouse’s mains electrical supply. Telehouse’s backup systems operated as designed. The UPSes picked up the load without missing a beat and kept everything ticking over until the generators could be brought on-line. They had enough diesel to keep the generators running for three days. Nobody had predicted a scenario where the electricity supply would be cut off and fuel delivery trucks would be banned from Manhattan Island for over three days. But it happened.

Strings were pulled; a tanker got through. But then another unpredicted event occurred. Just as people can’t breathe freon for more than a few minutes, diesel generators can’t breathe smoke and dust for more than a few days. Telehouse Manhattan was off-line for over 30 hours.

Only in America

Posted by Polonius on 1 October, 2006

I am indebted to FrinkTank for drawing my attention to Jimmy Dean chocolate chip pancakes & sausage on a stick. I thought this must be a joke, and I haven’t found the chocolate chip version on Jimmy Dean’s Web site, but I have come pretty close with the blueberry, so it looks like these things are the genuine article.

I know that there is a long tradition of mixing sweet and savoury foods. Pork and apple sauce, or turkey and cranberry sauce seem to work well enough together. Here in Scotland it’s not unknown to have fruit pudding as part of a breakfast fry-up. I’ve even tried chicken and chocolate (although that was quite a bitter chocolate). But the idea of combining sausages and chocolate chips is bizarrely American, and serving the result onna stick is worthy of CMOT Dibbler himself.
