Single Points of Failure

Single points of failure pop up in the strangest of places. I’ll never forget the day when a colleague noticed a lonely single orange (fiber) cable coming out of a giant disk array. We were working in a data processing facility where the world’s largest computer manufacturers dropped off their latest-greatest technology for us to evaluate and bang on. The manufacturer was so impressed that he noticed an oversight on their part that they flew him out several times to meet with their engineers and review their designs in person. Sometimes seeing the obvious stuff makes you the expert.

In a similar vein, I was just reading a post in alt.folklore.urban that claims a US Navy Vessel was almost completely disabled when Inertial Navigation Systems (INS) went offline:

For close to a week and a half an Aegis class destroyer ended up piloted through shallow extreme-Northern Arabian Gulf waters by a combination of extremely cautious steering, celestial navigation, dead reckoning, and the occasional check by landmarks if we got too close to an oil platform.

[…]

More nerve-wracking for the rest of us was the fact that all our weapons systems with the exception of the Phalanx Close-In Weapons System are dependent on the INS for levelling information, the failure of which turned them into so much useless scrap. Those of us dealing with our one offensive weapons system, Tomahawk, regarded it as a grand vacation during which we didn’t have to notify the entire chain of command up to CentCom that we would be down for routine maintenance.

I’d be surprised if they don’t regularly practice running the ships on reduced navigability or impaired systems, but with today’s rapid-development and release industries it seems more prudent then ever to double-check for redundancy, in case of failure.

Techno-fibbing

Two stories were posted in the news today that have an interesting relationship. First, Reuters has reported on a UK study that people find it easier to tell lies when they do not have to be in the physical presence of their audience:

Just over half of respondents said using gadgets made them feel less guilty when telling a lie than doing it face to face, the study on behalf of financial services group Friends Provident found.

[…]

The survey found that while people were dishonest, most told lies with the best intentions and to spare others’ feelings.

Sounds like proof of common sense to me. Everyone likes to justify their actions in the best possible light, and it’s definitely less encumbered to speak freely into a piece of plastic than to interact with a real live person.

Second, the Associated Press has reported on a Fire Department in Tennessee that told a white lie to a caller in order to unravel a string of prank 911 calls:

After receiving a false report of a gas leak on Dec. 14, firefighters compared notes.

They confirmed 15 fake 911 calls over a two-month period, including four house fires, six car crashes and various other medical emergencies. All came from the same cell phone.

So they called the number and left a message saying the phone’s owner had won a gift card from a major retailer, Fire Capt. Brent Seymour said.

With so many people up in arms over privacy as it related to their cell phone, I find it notable that the fire departments may be the last group in America to have access to data. They probably just do not have the kind of leverage (what, with saving lives and property?) that large marketing and advertising companies will as they cozy up to telecom providers.

Needless to say, as the study above suggests, the prank 911 caller tried to say he had the “best intentions”:

Harms, 29, told authorities he thought he was doing taxpayers a favor by drawing otherwise lazy firefighters out of their cozy fire halls, according to court papers.

US Strip Search Apology

Another case of airport security in America gone horribly wrong:

The Homeland Security Department sent a letter apologizing to a Muslim woman who was detained at the Tampa airport and strip searched at a county jail.

Safana Jawad, 45, a Spanish citizen who was born in Iraq, was detained on April 11 because of a suspected tie to a suspicious person, authorities said. She was held for two days before being deported to England.

Why England?

Jawad was traveling to Clearwater to visit her 16-year-old son, who lived with her ex-husband, Ahmad Maki Kubba. Kubba, an Iraqi exile and American citizen for 27 years, was praised last year by Gov. Jeb. Bush for organizing a group to vote in Iraq’s election.

Kubba said his ex-wife’s detention prompted his son to move to Spain.

“I lost my son because of what happened,” Kubba said. “My son wanted to be in the U.S. Navy, and he speaks both English and Arabic. He would have been just what they are looking for. What they did to Jawad was unfair and is hurting America.”

Of course no one at the jail was found in violation of the rules, because the rules indicate you can do just about anything to anyone in the name of security. At least the rule enforcers didn’t send her off to one of the non-existent CIA “black sites”.

Identity and the Slovenian Euro

Preseren EuroNice that the Slovenian’s have decided to honor their most well known poet France PreÅ¡eren by putting his likeness on their new Euro coins. The bank has an amusing story (PDF) behind the reason for adding a signature below the likeness of someone so famous:

Unfortunately, PreÅ¡eren’s image remains largely unknown, despite the great number of “well known portraits”. For that reason we have decided to put his handwriting on the coin, as a sure confirmation that it is authentic PreÅ¡eren. We use the poet’s silhouette in releif (after Dremelj’s portrait) because it attests to the “poetic character” of this little-known representation in a contemporary manner.

And even if you look closely at the coin, I suspect his true image will continue to remain largely unknown. Funny and rather strange twist of identity logic. “Officer, please note that I consider myself a poetic character so my identity card has a rather ambiguous photo on it instead of the normal portrait.”

Should we recognize his signature any more than an image?Trubar apparently has a more well-known portrait, despite being alive hundreds of years earlier, and so they only put examples of his typography on the coin.

Speaking of identities, I also noticed that the Carinthian stone was given a place on the Slovenian currency, although Carinthia is actually an area that spans an informal Slovenian province and an Austrian federal state.
