Majority of Wireless Microphones will become Illegal to Use..

Posted by presson on January 23, 2010

Due to the spectrum reshuffle from switching television to digital broadcasts, a large section of wireless microphones used in houses of worship, clubs, and schools will become illegal to use after Jun 12, 2010.  Specifically microphones that use 698MHz through 806Mhz are what will no longer be allowed. Many of the top-of-the-line microphones can be programmed to use frequencies below 698MHz, but these systems typically are $1000 and above in cost.    Two manufactures are offering trade-in-rebates to help defer the cost of the change.  The biggest problem with this is actually getting the word out to the owners of these systems, since it’s not tracked.   So think about your community who may use them and ask if they are aware of the upcoming change. http://arstechnica.com/tech-policy/news/2010/01/time-for-churches-to-come-to-jesus-on-wireless-mic-legality.ars?utm_source=rss&utm_medium=rss&utm_campaign=rss

Tales of Nuclear Safety

Posted by presson on January 20, 2010

Back in December 2007, the main nuclear reactor that supplies the majority of the worlds supply of cobalt-60 and almost half of the world’s supply of Tech-99 had to be shut down.  This create a shortage of diagnostic and therapeutic nuclear medicine.  Apparently the Canadian government saw this possibility and started creation of two new reactors as backups; however, these had to be essentially scraped due to a miscalculation of the power coefficient of reactivity (PCR.)   A negative PCR means as the reaction increases, the design of the reactor is such that the reaction will slow down in a negative feedback loop.  The only problem was when they started tests, it actually had a positive reaction, meaning it would continue to build unless other safety measures were enabled (inserting rods for example to slow the reaction.)  Since the negative PCR was part of the safety spec, it was not allowed to continue. 

 

It’s an interesting read:  http://www.newscientist.com/article/mg20527431.400-nuclear-safety-when-positive-is-negative.html?DCMP=OTC-rss&nsref=online-news

The Sound of Snow..

Posted by presson on January 10, 2010

image Having our first real snow of the year reminded me of something I heard as a kid:  when you walk on snow you can gauge the temperature by the pitch of the ‘squeak’ or ‘crunch’ it makes.   So of course I decided to do some fact finding, or at least search the web.   I found an interesting summary from this blog:  http://blog.sciencegeekgirl.com/2008/12/29/why-does-snow-crunch-under-your-feet/  as well as a link to the National Snow and Ice Data Center:http://nsidc.org/snow/faq.html 

Apparently at about –10°C   there is a change in sound from ‘Crunch’ to a ‘Squeak.’  They suggest there is a thin layer of water on the crystals lubricates above –10°C and does not below –10°C , the squeak sound comes from the crushing of the ice crystals.    

I was unable to find anything that indicated the pitch of the squeak changes.  On a different note, I noticed last time we visited the beach that my bare feet on the sand causes a similar type of sound.  

 

In any case, next time you go for a walk in the show, listen..

Widespread Y2k16 hits Windows Mobile

Posted by presson on January 3, 2010

image Apparently tons of cell phone carriers are having a problem with SMS messages showing a 2016 date instead of 2010, mine included.  Interesting thing is 10 in HEX is 16 in decimal, so perhaps the date storing formula as a slight bug?  read more here: http://tech.slashdot.org/story/10/01/03/1312209/2016-Bug-Hits-Text-Messages-Payment-Processing

30 Meter Telescope Dwarfs Them all

Posted by presson on December 5, 2009

tmt

“The enormous Thirty Meter Telescope, with a primary mirror the size of a blue whale, is part of a new generation of super powerful ground-based telescopes. Scheduled for completion in 2018, it will have nine times the collecting power of the Keck telescopes and 12 times the resolution of the Hubble Space Telescope. From its recently selected location atop the volcanic dome of Mauna Kea in Hawaii, the pioneering telescope will provide an extremely detailed look at the universe.”

TechNet Direct – Get most Microsoft Software for Cheap

Posted by presson on December 4, 2009

image Yes this is legal.  Yes it is a good deal:  for example: get Windows 7 Ultimate, Server 2008 R2, Sql Server, Microsoft Office Ultimate 2007, etc for $349 – 28%  of the cost using this code: TMSAM07   so the total cost is $251.28.  If you already have TechNet Direct, use the code to renew, and pay only $179.28 plus tax. $186.86 for me) 

People: this is good for ~10 copies of Windows 7 Ultimate, plus 10 copies of Office 2007 Ultimate.  all for HALF the cost of one retail copy of Windows 7.

 

go to http://technet.microsoft.com  and upgrade all your systems cheap.  Hurry, these codes don’t last long..

 

cheers.

How Your Brain Filters Distracting Thoughts

Posted by presson on November 24, 2009

image What was I saying?  Oh yes, apparently the idea that your brain uses gamma ways frequency to differentiate current experiences from past experiences.  “They found that the hippocampus selectively tunes in to different frequencies of gamma waves coming from different brain areas. The lower gamma wave frequencies are used to transmit memories of past experiences, and the higher frequencies are used to convey what is happening where you are right now.”

Duplicate SID problem? Nope.

Posted by presson on November 9, 2009

For years the mantra has been you have to use sysprep or sidwalker if you make an image of a pc before deploying it to other servers/workstations.  It turns out that is true, but ONLY if it is a domain controller.    Otherwise there is no need, at least according to Mark: http://tech.slashdot.org/story/09/11/04/0040203/The-Machine-SID-Duplication-Myth?from=rss

Flexible Solar Cells Generate Electricity at the Same Cost as Coal

Posted by presson on September 21, 2009

Nanosolar has a manufacturing facility churning out flexible solar cells on aluminum foil.  They claim they could produce electricity at five to six cents per kilowatt hour, which is 3-4 times less expensive than current methods.  This brings solar cells electricity generation down to the same cost as coal.    Now why hasn’t this gotten the attention of the US government..?
