10 of The Worst and Stupid Engineering Mistakes

The list below feature 10 of the worst and stupid mistakes ever made in the engineering field.

1. St. Francis Dam, 1928
Self-taught engineer William Mulholland built this LA dam on a defective foundation and ignored the geology of the surrounding canyon. He also dismissed cracks that formed as soon as the reservoir behind it was filled. Five days later, it ruptured, killing 450 people and destroying entire towns (along with Mulholland’s career).

2. Kansas City Hyatt walkways, 1981
Walkways crisscrossing the hotel’s multistory atrium collapsed, domino-style, raining debris and hundreds of people onto the packed dance contest below. The cause: grossly negligent design and use of beams that could support only 30 percent of the load.

3. Vasa, 1628
Three hundred years before the Titanic, the Vasa was the biggest sailing vessel of its day. The overloaded ship ruled the seas for all of a mile before she took on water through her too-low gun ports and promptly capsized.


4. Northeastern US power grid, 1965
A single protective relay tripped in Ontario, overloading nearby circuits and causing a cascade of outages that left 30 million homes without power for up to 13 hours. A fragile, redundancy-free design ensured that it would happen eventually. After decades of repairs and upgrades, it happened again in 2003.

5. McDonnell Douglas DC-10, 1970s
Nearly a thousand people around the world lost their lives while the kinks were being ironed out of this 290-ton competitor to Boeing’s 747. Blown-out cargo doors, shredded hydraulic lines, and engines dropped midflight were just a few of the behemoth’s early problems.

6. Firestone 500 tires, 1970s
These steel-belted radials allowed water to seep under the tread, which caused the belting to rust and the tread to separate, typically at high speeds. Dozens of deaths later, Firestone blamed consumers, then recalled 10 million tires.

7. Purity Distilling Company tank, 1919
You gotta keep your molasses somewhere – how about a rickety tank 50 feet tall and 90 feet in diameter in the middle of Boston? The structure was painted brown to hide the leaks. Eventually it burst (possibly exploding from fermentation), sending waves of molasses up to 15 feet high into the city and killing 21.

8. Skylab, 1973
America’s first space station was hopelessly damaged at launch because designers failed to account for the aerodynamics of the meteoroid shield and solar panels. When crews weren’t busy making repairs, they complained of the extreme heat on board.

9. Citigroup Center, 1978
Last-minute changes to structural braces of this Manhattan tower left it vulnerable to collapse in high winds. With a hurricane bearing down on the city, builders rushed to strengthen it by welding 2-inch steel plates over 200 weakly bolted joints.

10. R101 airship, 1930
Seven years before the Hindenburg disaster, the British thought 5.5 million cubic feet of hydrogen in a bubble of fabric would make for a fun way to get around. On her maiden flight, the airship’s cover was blown open by wind, and from there it was oh-the-humanity city.

Top 10 Hottest Celebrities 2005

1. Fallen R&B star Bobby Brown, for setting the record straight on Saint Nicholas. Carving up a ham and surrounded by family and friends on his TV holiday special Being Bobby Brown: Christmas With the Browns, the singer looks straight into the TV camera and states, “Kids, I want to tell you there’s no such thing as Santa Claus.” Teenage daughter Bobbi Kristina tries to intervene, saying he’s just kidding, while Brown insists, “I’m not kidding, there’s no Santa Claus.”

2. Singer Janet Jackson, for being the most popular name search on Internet search goliath Google this year. Jackson made headlines in October when reports she had a teenage daughter with her ex-husband James Debarge surfaced. Weeks later, a recording of Jackson sunbathing in the nude was leaked onto the Web.
 
3. Former 24 star Elisha Cuthbert, for taking the time to write, of all things, an ice hockey blog on North America’s National Hockey League official Web site, NHL.com. Continue Reading →

Top 10 Hacks of All Time

Early 1990s

Kevin Mitnick, often incorrectly called by many as god of hackers, broke into the computer systems of the world’s top technology and telecommunications companies Nokia, Fujitsu, Motorola, and Sun Microsystems. He was arrested by the FBI in 1995, but later released on parole in 2000. He never termed his activity hacking, instead he called it social engineering.

November 2002

Englishman Gary McKinnon was arrested in November 2002 following an accusation that he hacked into more than 90 US military computer systems in the UK. He is currently undergoing trial in a British court for a “fast-track extradition” to the US where he is a wanted man. The next hearing in the case is slated for today.

1995

Russian computer geek Vladimir Levin effected what can easily be called The Italian Job online – he was the first person to hack into a bank to extract money. Early 1995, he hacked into Citibank and robbed $10 million. Interpol arrested him in the UK in 1995, after he had transferred money to his accounts in the US, Finland, Holland, Germany and Israel.

1990

When a Los Angeles area radio station announced a contest that awarded a Porsche 944S2 for the 102nd caller, Kevin Poulsen took control of the entire city’s telephone network, ensured he is the 102nd caller, and took away the Porsche beauty. He was arrested later that year and sentenced to three years in prison. He is currently a senior editor at Wired News.

1983

Kevin Poulsen again. A little-known incident when Poulsen, then just a student, hacked into Arpanet, the precursor to the Internet was hacked into. Arpanet was a global network of computers, and Poulsen took advantage of a loophole in its architecture to gain temporary control of the US-wide network.

1996

US hacker Timothy Lloyd planted six lines of malicious software code in the computer network of Omega Engineering which was a prime supplier of components for NASA and the US Navy. The code allowed a “logic bomb” to explode that deleted software running Omega’s manufacturing operations. Omega lost $10 million due to the attack.

1988

Twenty-three-year-old Cornell University graduate Robert Morris unleashed the first Internet worm on to the world. Morris released 99 lines of code to the internet as an experiment, but realised that his program infected machines as it went along. Computers crashed across the US and elsewhere. He was arrested and sentenced in 1990.

1999

The Melissa virus was the first of its kind to wreak damage on a global scale. Written by David Smith (then 30), Melissa spread to more than 300 companies across the world completely destroying their computer networks. Damages reported amounted to nearly $400 million. Smith was arrested and sentenced to five years in prison.

2000

MafiaBoy, whose real identity has been kept under wraps because he is a minor, hacked into some of the largest sites in the world, including eBay, Amazon and Yahoo between February 6 and Valentine’s Day in 2000. He gained access to 75 computers in 52 networks, and ordered a Denial of Service attack on them. He was arrested in 2000.

1993

They called themselves Masters of Deception, targeting US phone systems. The group hacked into the National Security Agency, AT&T, and Bank of America. It created a system that let them bypass long-distance phone call systems, and gain access to private lines.

Top 10 Cities for Quality of Life in 2006

According to the 2006 Quality of Living Survey by MERCER, here is the top 10 cities for the best quality of living.

The rankings are based on data collected between September and November 2005 and the data is regularly updated to take account of changing circumstances. Only 215 cities have been considered in the Quality of Living 2006 rankings and any assessment will be revised in the case of any new developments.

  1. ZURICH, Switzerland
  2. GENEVA, Switzerland
  3. VANCOUVER, Canada
  4. VIENNA, Austria
  5. AUCKLAND, New Zealand
  6. DUSSELDORF, Germany
  7. FRANKFURT, Germany
  8. MUNICH, Germany
  9. BERN, Switzerland
  10. SYDNEY, Australia

My 2 Cents

7 cities from Europe made it to the top 10 list, Europe is certainly a place to be. Sadly, none of Asian cities made it to the top 10.
