than the perpetually self-employed and the perpetually unemployed (aka bums), most people have been to at
least one job interview. Even after multiple interviews over many years, I was always nervous - mainly because
I really wanted the particular job being advertised - so messing up wasn't an acceptable option. Because the
companies I chose to apply with were all highly respected, there were never any instances of the interviewers
being idiots or hostile. I've been lucky. A lot of people have not been so fortunate. One person that called
recently told of being asked about how he'd approach solving a certain problem, and then the interviewer
called him back again a few days later to get additional detail about his idea for troubleshooting, ostensibly
to gain more insight into his abilities. It turns out that he thinks he solved a problem for them, and that
the company was just exploiting interviewees to get free consulting. That's the stuff of Dilbert comic strips,
which, unfortunately, are largely based on stories that Scott Adams gets from people's real-life experiences.
Here is a classic Monty Python video of an interview from Heck.
a teacher in public schools is a demanding job, so they tell us. The students have no self-discipline, and the
school rules prevent the teachers from taking effective action to control the classroom. Of course, their own
representatives have brought it on them through politically correct mandates. My sister has been a teacher for
30 years, and boy have I heard some stories about moronic students and parents. The students' inconsiderate
behavior of course is carried over into the college classroom. There, though, especially at private
universities like Cornell, the rudeness is likely to be quashed by a professor. This video shows that exact
scenario when someone blurts out a very loud yawn during class. I side with the prof.
teenage scientist Eric Jacqmain has created a
YouTube sensation with his "Solar Death
Ray." Per Eric, "The R5800 is my latest and greatest solar creation. Made from an ordinary fiberglass
satellite dish, it is covered in about 5800 3/8" (~1cm) mirror tiles. When properly aligned, it can generate a
spot the size of a dime with an intensity of 5000 suns! This amount of power is more than enough to melt
steel, vaporize aluminum, boil conc
rete, turn dirt into lava, and obliterate any organic material in an
instant. It stands at 5'9" and is 42" across." The performance is pretty amazing, especially given its
low-tech approach. It would be interesting to know whether Mr. Jacqmain has sustained any flesh burns while
holding objects in the focal point. I would not be holding anything in my fingers while searching for the hot
spot. Ironically, the shed used for storing the R5800 burned down; maybe it was facing a window with a
you are one of those outdoor types who loves to explore dangerous environments, watch closely. This video
shows what can happen when a crocodile decides to eat an electric eel for dinner. It is an amazing, albeit
gory, sight to behold. In a more urbane demonstration of the electric eel's potential (pun intended), an
aquarium in Japan lights a Christmas tree with the charge supplied, compliments of the beast in a tank. The
electric eel is actually not an eel, but a knifefish. It breathes air at the surface, then dives for 10
minute periods. It can generate up to 500 volts at 1 amp (500 watts), delivered at 10 Hz up to a few hundred
Hz. Recall that it only takes
1/10 amp to kill a man. At 500 V,
a body resistance of less than 5 kΩ spells doom.
near-field communications (NFC), magnetic strips, movement-tracking radars in grocery and department stores,
all are systems designed to facilitate efficient merchandizing. Even when used legally, many aspects of the
science are cause for concern from a privacy perspective. Visions of Orwell's Big Brother immediately come to
mind, where an overarching, omnipresent government monitors and controls the movement of society's pawns...
er, citizens. Distributors and users of the sensor products (RFID, NFC tags) and tracking systems range in
complicity from useful idiots (sorry, but that's a well-defined term from the
to prosecutable criminals. The overwhelming majority (including myself) are part of the former. Marketing
firms, government entities, and street vermin make up the
self-proclaimed wizards of smart in the lamestream news media have once again been exposed. Off-air gaffes and
brazen displays of bias are de rigueur with these idiots who pretend to be intellectual, objective, and
neutral while on air. When they think the cameras and microphones are off, caution is tossed to the wind, the
outer skin is shed, and the true nature comes out. Here we see a pre-show segment of NBC's Today show
where clueless Katie Colic and Bryant Gumball wondering what is this newfangled thing called the Internet,...
Oh, in the spirit of NBC's philosophy of tolerance and bringing the results of investigative reporting to the
world, as it ostensibly does with shows like Dateline, it summarily fired the guy who leaked this
video. The hypocrisy of the elite continues to amaze. <more>
Stewart has a great satire on Verizon's announcement for adding the iPhone to its repertoire. In his trademark
wry presentation style, Stewart treats us to the riveting public event where Verizon CEO Lowell Mcadam stirs
the audience to a level of passion not witnessed since ClingFree™ dryer sheets hit the market. Street reporter
John Oliver gets heart-wrenching stories from AT&T iPhone users whose live have been destroyed by the near
criminally substandard service. Rituals reminiscent of the proletariat's toppling of Saddam Hussein's statue
in Iraq are filmed in the joyous announcement by Verizon. You'll want to watch it.
the spirit of the season, I have made a tradition of posting a few of my favorite online Christmas music
an eclectic mix of "Christmas Eve in Sarajevo" and Pachelbel's "Canon in D," by Trans-Siberian Orchestra.
This "Carol of the Drum,"
(aka "Little Drummer Boy") duet by by Bing
and David Bowie is an amazing blend of the old and the new.

read a lot about the early radar system that was in operation at Pearl Harbor in December 1941 when the
surprise attack by Japanese naval airplanes decimated the fleet with a 3-hour-long raid beginning at around
8:00 on that sleepy Sunday morning. The SCR-270B (Signal Corps radio #270, rev B) radar system had a range of
250 miles at an altitude of 50,000 feet. Westinghouse built the system in 1940 following a development
contract issued by the Army Signal Corps in 1936. Radar's roots goes back to the late 19th century when
Heinrich Hertz conducting experiments of radio signals being reflected off metal surfaces. In 1904, German
scientist Christian Hülsmeyer gave a demonstration of his "telemobiloskop." By the early 1930s, the U.S.,
Great Britain, Germany, the USSR, Japan, the Netherlands, France, and Italy, were all working on radar
development programs. <more>
seems like every year we see videos posted of icicles falling from television station transmission towers,
crashing into vehicles in the parking lot. This one from
WJTV News Channel 12, in Jackson, Mississippi,
stands out because it shows people actually running toward their cars while the icicles are falling from a
491-meter high tower. They apparently are so concerned about damage to their vehicles that they discount the
potential for mortal harm if one of those gigantic icicles happened to hit them. You can hear the people
laughing as they run into harm's way. One day we'll see one of them in the annual list of Darwin Award
winners. Sad, but true.
and tinkerers of all ages have enjoy a long, synergistic relationship that has led to incredible creations of
mechanical contraptions and artistic sculptures. I have reported previously on LEGO re-creations of the
Babbage Difference Engine, a
Fender guitar, and even full-size
(do a search on
LEGO images). Now, an Apple engineer has re-created the long-lost and recently-found Greek
Antikythera Mechanism. 1,500 LEGO blocks and 110 gears were combined over a 30-day period of designing,
building, and testing to produce this mechanical wonder. Maybe Apple should assign this guy to design the iPod
5 antenna - or at least the long-awaited iPod 4 white case!
