Las Vegas renumbered this year, Seattle has renumbered recently, its a regular thing. depending on where you are the magnetic variation can easily shift 0.5-1.0 deg / year. Usually the runway renumber happens when the mag heading shifts across the 5 deg boundary. most runways are built on ordinal true headings that are then converted to the nearest 10 deg magnetic equivalent for numbering. my local example is DEN - rwys 7/25 and 8/26 are currently both 82.1 mag with 8.4E mag var or 90 true. the mag var in DEN is changing 0.1 deg/yr W ( it was 9.6E in 2005 ).

Submission + - Ask Slashdot: How to deal with persistent and incessant port scanner
jetkins writes: What would you do if your firewall was being persistently targeted by port scans from a specific group of machines from one particular company?
I run a Sophos UTM9 software firewall appliance on my home network. Works great, and the free Home Use license provides a bunch of really nice features normally only found on commercial-grade gear. One of those is the ability to detect, block, and report port scans, and under normal circumstances I only get the occasional alert when some script kiddie comes a-knocking at my door.
But in recent months I have been getting flooded with alerts of scans from one particular company. I initially reported it to my own ISP's (RoadRunner's) abuse desk, on the assumption that if they're scanning me then they're probably scanning a bunch of my neighbors as well, and any responsible ISP would probably want to block this BS, but all I ever got back was an automated acknowledgement and zero action.
So I used DNS lookup and WHOIS to find their phone number, and spoke with someone there; it appears that they're a small outfit, and I was assured that they had a good idea where it was coming from and that they would make it stop. Indeed, it did stop a few days later but then it was back again, unabated, after another week or so. So last week I called them again, and was once again assured of a resolution. No dice, the scans continue to pour in.
I've already blocked their subnet at my firewall, but the UTM apparently does attack detection before filtering, so that didn't stop the alerts. And although I *could* disable port scan alerts, it's an all-or-nothing thing and I'm not prepared to turn them off completely.
This afternoon I forwarded the twenty-something alerts that I've received so far today, to their abuse@ address with an appeal for a Christmas Miracle, but frankly I'm not holding out much hope that it will have any effect.
So, Slashdotters, what should I do if this continues into the new year? Start automatically bouncing every report to their abuse address? Sic Anonymous on them? Start calling them every time? I'm open to suggestions.

Contractors are preferred because when the contract is over the workers are not still on the government payroll. If they hire workers directly they would be covered by the civil service rules and be effectively employed for life no matter how bad they were. This shows up all the time when there is a need to change or slow down a program the contractors are in the news because of large layoffs.

Comment where are the unused channels located (Score 2) 107
I just looked in the Denver Area using the Spaectrum Bridge system, there is 1 white space frequency available for use, all the others are already blocked by existing TV usage. that single 6Mhz slot means that at least in the denver city area trying to make use of "White Space" for networking is basically useless. I would like to see a map of the US with the number of channels available per 10 sq. miles plotted across the country. I'm guessing that there will be lots of bandwidth available where there are low population densities and little bandwidth available where most of the population is located.

there are no more NDB stations left in the USA and the FAA is working on turning off the VOR stations as soon as they finally get the WAAS GPS based nexgen navigation system working. The whole idea of the Nexgen Navigation system is to stop flying on airways defined by VORs and move to flying directly from point to point navigating by GPS only.. i predict a huge fight between the FAA and the FCC
Real Reason Why the White iPhone 4 Is Delayed 182
tekgoblin writes "There have been numerous reasons why the White iPhone 4 may be delayed with one reason being the color mismatch between the home button and the body. Well this time there is another reason. A source has told CultofMac that the reason for the delay is a light leakage issue caused by the case being clear. Light from the case leaks into pictures taken by the back and front camera on the white iPhone 4, causing distorted pictures. This problem is non-existent on the black iPhone 4, because of its already black case, so Apple has been looking for a solution to this problem, thus the delay of the White iPhone 4 till spring of next year."

actually the devices mush check the database at least daily, the TV station part is mostly unchanging, but the database also includes wireless mic users that are protected and those listing update daily. To be legal the TVBD must check the database for "today's" allowable frequencies. If the database can't be checked the TVBD must shut down till it can get a update from the database. see: http://www.fcc.gov/Daily_Releases/Daily_Business/2010/db0924/FCC-10-174A1.pdf pg 41
