+ - Perl is Undead!

Submitted by Ptolemarch
Ptolemarch (11506) writes "At the Yet Another Perl Conference beginning today in Orlando, the first keynote squarely blamed Slashdot for starting the "Perl is Dead" meme in 2005. He couldn't find the exact story he was thinking of, and, you know, neither can I, but let's be clear: if Perl was ever dead, it must now be undead. If you can't be at YAPC, you can still watch it live."

+ - The Earth is a gravitational wave detector->

b30w0lf (256235) writes "Gravitational wave detection—i.e. the detection of propagating ripples in spacetime—is a hot subject these days with ground-based interferometer experiments like LIGO active, and hopes for a space interferometer like LISA. But, physicist Freeman Dyson proposed back in 1969 that the earth itself could be used as a gravitational wave detector. The idea is behind the approach is that gravitational waves impact the earth’s crust, causing potentially detectable seismic waves. Using Dyson’s approach, Physicists at Harvard and NINP, Florence were able to put an upper limit on the intensity of gravitational background radiation based on a year of observational seismic data. The upper limit they found improved currently laboratory upper limits by 9 orders of magnitude."

Normal Slashdot has a "disable ads" button if you have good karma. I believe that is what they are rederring to.

Indeed. That's Maker mode, as I mentioned, though Maker mode doesn't get offered for merely good karma.

I've implemented ad hiding for Maker mode, but if I can reproduce a bug with it, I'll fix it.

The acquisition makes sense, in that they obviously want ratings of restaurants (and other places) on Maps, and they've already changed tactics there once or twice. This'll pretty much take care of that problem.

I start to wonder, though, whether any acquisition by Google wouldn't "make sense". Their purchase of Motorola Mobility makes sense, too (though not to everyone). When you buy a consumer electronics company and a restaurant guide in consecutive months, what won't you buy? What acquisitions won't "make sense"?

Google buys Pacific Gas and Electric for $20B. Makes sense...

+ - Wicked Lasers Sells One-Watt Green Laser->

cogent writes "Wicked Lasers, famous for last year's 1000mW handheld blue laser, and infamous for its handling of six-month-long backorders, is now selling a green version. There are three power levels, each priced at $1/mW. Since the eye is far more sensitive to green than to blue, this is pretty much the state of the art in putting-dots-on-stuff technology. Wicked Lasers sent out an email, promising to handle backorders much better this time."

+ - New Life for Waste Heat from Crematoriums

Submitted by
Hugh Pickens writes
Hugh Pickens writes writes "Justin Nobel writes that waste heat from a local crematory will soon heat water that will be piped to a nearby recreation center to heat the pool and the rest of the facility, saving about $23,000 a year in heating costs but some are asking if the process honors the dead or exploits them. “People are dying anyway, and many choose to be cremated," says Ceridwen John, the climate change manager in Redditch, England where the system is being installed. "Our options are to expel the waste heat into the atmosphere or to do something useful with it.” Redditch is acting in response to recent European Union legislation that requires crematories to reduce mercury emissions by 50 percent by 2013. Extracting the harmful mercury from dental fillings requires cooling flue gas from 800 degrees Centigrade to 150 degrees so the waste heat is pumped through a heat exchanger where it can be used to generate power. Will crematory heat ever become popular in the US? "Some grieving families like the idea of their loved ones 'giving back something'," says Tim Morris, chief executive of the Institute of Cemetery and Crematorium Management. "I see that becoming predominant, and this research as an opportunity to do something innovative and respectful to the funeral mourning process.""
