I remember those heady days well. But over time slashdot's lost relevance to me. I stopped posting long ago as the quality of the discourse dropped, and I started linking directly to most of the sites slashdot regularly references. I also became unable (or unwilling) to comprehend the complicated comment filtering crud several years back (really, what's up with that?)

I do have slashdot to thank for helping me discover arstechnica - which has mostly replaced slashdot for my tech news discussion forum needs.

But still, I check slashdot daily.

Have fun Rob, enjoy your family, and find something new and interesting to do.

Just have the darned black box broadcast all of its data once every millisecond. Put receivers on satellites and on grounds stations or even on other planes. Give the transmitter a range of several thousand miles, and come up with some scheme to avoid broadcast collisions (either time or code division multiplexing).

If a plane goes down go back to the recorded transmissions, of which there should be multiple copies.

The reason you are experiencing pain is that one side of the thick wedges of foam in your shoe has lost it's spring, turning your shoe into a crappy little ramp that actually accentuates whatever that wedge was meant to correct.

The proper corrective for poor form is not a running shoe. It's either running barefoot, or running in a shoe with a thin rubber sole that serves as protection only. Try if for a month, but build your miles slowly. All the muscles, tendons and ligaments that your current shoes have allowed to atrophy will build up, and eventually you will be running like nature intended, with nearly perfect form.

You can protect your feet without slapping an inch thick slab of foam rubber under them.

I run in thin soled canvas shoes and have never had an injury from stepping on something. In fact I've had fewer ankle turn injuries as I can actually feel the surface and react if I've stepped on something that might cause my foot to slip or roll.

Math Prof Uncovers Secret Chord 177

chebucto writes "The opening chord to A Hard Day's Night is famous because for 40 years, no one quite knew exactly what chord Harrison was playing. Musicians, scholars and amateur guitar players alike had all come up with their own theories, but it took a Dalhousie mathematician to figure out the exact formula. Dr. Brown used Fourier transforms to find the notes in the chord, and deduced that another George — George Martin, the Beatles producer — also played on the chord, adding a piano chord that included an F note impossible to play with the other notes on the guitar."

Infrared radiation: The other wireless technology

Submitted by StonyandCher
StonyandCher writes "Although the recent auctioning of the 700MHz wireless spectrum bands have garnered great interest in the media (not to mention the billions of dollars being thrown around to own some of this), it's not the be-all and end-all answer to our wireless hunger.

New research is starting to be conducted in the area of infrared radiation. Cheap to develop infrastructure for, super fast and with huge amounts of spectrum available (literally many terahertz), is this the unlicensed answer to the dearth of wireless spectrum? This article delves deeper into the world of IR and looks at its pros and foibles."

Start an IT career at age 40? 2

Submitted by
An anonymous reader writes "How viable is it to start an IT career at age 40? I have heard there is a lot of age bias in the IT industry. I have a science degree and programming experience, and I think IT would be more interesting and higher paying. Anybody have any hints on getting your foot in the door? How bad is the age bias and will it make a career too difficult to maintain? (I have heard of 40-year-olds losing their job and taking years to get a new one in the IT industry)"

Promptness is its own reward, if one lives by the clock instead of the sword.
