Computers Can’t Be Trusted

“Computer problem.” I’ve heard those two words a million times. Mostly, it’s a crock. Computer problems aren’t usually computer problems but problems which appear when humans operate computers. In other words, it’s mostly human error.

Computers only do what they’re told. Hardware failures that allow them to run amok are relatively rare. It’s that fingertip/keyboard interface where all the trouble arises.

With that perspective, it’s off to Chicago where, earlier this week, WGN radio found itself broadcast all over the radio and TV dial. I was tipped off to this story by Adam Chernow in Wisconsin, but I’ll quote the Chicago Tribune:

In the parlance of the Cold War era that spawned the federally mandated Emergency Alert System, launch codes were issued throughout Illinois on Tuesday morning, automatically pre-empting dozens of radio and television stations as if the region faced nuclear annihilation.

Rather than President Bush reassuring citizens after an atomic blast or some other calamity, the audience of many Chicago outlets was treated to the sound of dead air followed by the voice of WGN-AM 720 morning man Spike O’Dell struggling to figure out what had happened.

It turns out O’Dell’s pair of brief surprise appearances between 7:30 a.m. and 8 a.m. on everything from local public broadcasting to music stations — an “unintentional disruption,” a Federal Emergency Management Agency spokeswoman called it — stemmed from a FEMA contractor’s installation of the state’s Emergency Alert System satellite receiver in Springfield as part of a nationwide upgrade.

If the contractor had asked me to call all those stations, I would have pointed out the error of his ways. Computers are more obedient and, unfortunately, don’t question authority!

Why do we do this? Why do we allow an automated system take control so an errant human can cause chaos?

I know why. I was there the morning the old system failed!

It was February 20, 1971. As I remember, it was a sunny and mild winter’s day. I was working as a disk jockey at WQXT, located right on the ocean in Palm Beach, Florida. Life was good.

At 9:33 AM a series of ten bells rang out from the Associated Press teletype. Ten bells was the signature for a national emergency, an EBS alert… but this was Saturday at 9:33 AM. They tested the system every Saturday at 9:33 AM.

Somewhere deep within Cheyenne Mountain in Colorado, a technician put the wrong put tape in his teletype. Instead of sending the test, he sent the real thing!

From Wikipedia: An EBS activation message authenticated with the codeword “HATEFULNESS” was sent through the entire system, ordering stations to shut down and broadcast the alert of a national emergency. A cancellation message with the wrong codeword was sent at 9:59 AM EST, and a cancellation message with the correct codeword was not sent until 10:13AM EST.

Most radio and TV stations did nothing! They had no way of knowing the message was wrong. In fact, every indication was it was real.

In my case, I heard the bells and disregarded them. It was test time. I heard those bells every Saturday morning.

By the time I looked at the teletype, the alert had been corrected. The few people listening to my little radio station were well served because I totally screwed up!

After that debacle the government worked to change to a better, faster, more streamlined, heavily automated system. And yet, with this week’s problem, the cause was exactly the same – human error.

It’s this automated system that has sometimes allowed cable companies to cut my television station’s audio as they run emergency crawls… even though we’re giving emergency info when they kill our audio!

Society has become so complex, we can’t operate without computer assistance. Unfortunately, that has forced us to put much too much power in someone’s fingertip. The folks in Chicago understand.

Comair – It Was The Software

A few days ago, while pondering the Comair Christmas meltdown, I said:

Comair isn’t letting me into their inner sanctum, but it’s probable that the structure of the computer system that handles their crew assignments, weight balance, manifesting and the like wasn’t equipped to handle all the ‘exceptions’ it was asked to ponder this past week.

I hit it right on the nose! Linked below is a story from today’s Cincinnati Post which details exactly what happened.

Comair says the computer system was due to be replaced. I wonder if the DOT inquiry will show it should have been replaced a while ago. How long was Comair operating close to the limits of their system? Was this problem predictable?

Cayman Island Earthquake

I was surprised, to say the least, to read about a strong earthquake tonight close to the Cayman Islands (20 miles southeast of Georgetown, the capital). Actually, there are a number of surprises for me here and I might as well run them down.

Though I knew there are plates upon which all of the Earth’s surface floats, I didn’t realize there was a boundary between two plates in the Caribbean. They grind against each other slowly, but constantly. The relative motion is only 6/10″ per year.

Of course one year is nothing to the Earth. Over 20 years that’s around a foot of motion. Over decades and centuries… well, you get the idea.

At some point something’s gotta give… and it did tonight. The quake was magnitude 6.7&#185. That’s enough to be very scary and even more destructive. I have not yet heard any damage reports from the Caymans. Magnitude alone is not enough to predict destruction.

My second surprise was seeing actual ‘shock reports‘ from the Cayman Islands. This is actually an interesting idea from the United States Geological Service. They ask people to check in and rate the quake! It’s like Dick Clark on American Bandstand circa 1965.

As I type this there are 189 reports from the Caymans and one from Haiti. Each locale is averaged to show how the quake was felt.

I think the USGS does an amazing job keeping up with earthquakes. Their website is fast and thorough. I’m a math and science guy, so it appeals to me more than most. Still, if you’re curious, it’s worth looking at.

And, to get my own little plug in, there’s a link to the most recent large earthquake in the column on the right: Latest Large Earthquakes Worldwide.

&#185 – Remember Richter? The Richter scale is no longer in use by geologists.

Ted Koppel – Who Knew?

I just read an article in the Wall Street Journal considering the future of Nightline. I remember the origins of that show, during the Iran Hostage Crisis. In the beginning, the nightly show would even give the count of days since the hostages had been taken.

I remember the first time they strayed from Iran and covered some other breaking news. It was sharp, learned and the only show of its kind in that pre-cable age.

Now, the article says, ABC might be trying to kill off the show.

I usually get to see the first minute or two before leaving work. Though thoroughly associated with Ted Koppel, he’s not there too often. Now, I understand why.

Mr. Koppel’s contract expires in 2005, and he is unlikely to sign a new one that involves many changes to his current situation. His contract gives him nearly two months of vacation, a three-day workweek and a provision that the show is rarely broadcast live — a grueling option that characterized “Nightline” in its heyday. Mr. Koppel also takes home a paycheck thought to be near $10 million — on par with top-paid figures in network news. A spokeswoman said Mr. Koppel was not available to comment.

$10,000,000! I’m in the wrong busine… Oh, hold on. Same business. Never mind. And, with all due respect to Mr. Koppel whom I consider a gift to television journalism – grueling? Please!

I’m not sure if Nightline could make it today as a live show. We had longer attention spans twenty years ago. There was less competition.

Sometimes good things just outlive their usefulness. It will be a shame when that happens to Nightline, because it was so special.

Look Ma – I’m on Slashdot

I love Slashdot. How could I stay away from a site whose slogan is “News for Nerds. Stuff that matters.”

I am there at least 4-5 times a day, following their links to see the latest in high tech. It is Linux biased in much the way The Catholic Church is Christian biased. But, it’s geek and nerd populated and I share a certain sensibility with many of its habitues (though, unfortunately I no longer share the same generation with them)

Its readers, rapidly responding to the story postings, add insight, insult and everything in between.

What makes Slashdot so effective is its self moderating system which starts limiting what you easily read (you can always get to everything, but probably don’t want to) as users come on and rate the postings. Judging by what I see, there are a lot of people moderating at any given time, though Slashdot only gives you the opportunity to moderate every once in a while. Then, later, the moderations get moderated!

In many ways it is analogous to Google, where your association with others decides your relative importance and where your links appear.

Anyway, I’m writing all this because I finally got a posting of mine on to start a thread. It started this morning, early, when I saw an article in the New York Times about speeding up media (listening at double speed, for instance) and how that is a burgeoning field.

I have used that same technique in my studies at Mississippi State, watching DVD’s at double speed. For me, it’s been very effective. Now, it’s shared with others.

Phantom Lightning

As the power failure/blackout story progresses, the Canadian power authority has begun to blame a lightning strike in Northern New York State.

This would be a subject I have some expertise in. So, take my word. There was no lightning strike in Upstate New York this afternoon that might have set off the blackout. Period. End of story.
