Submission + - UK ISPs Respond to the Dangers of Using Carrier Grade NAT Instead of IPv6 (ispreview.co.uk)

Mark.JUK writes: "Several major Internet Service Providers in the United Kingdom, including BSkyB, Virgin Media, TalkTalk, AAISP and Fluidata, have warned that the adoption of Carrier Grade NAT (IPv4 address sharing) is likely to become increasingly common in the future. But the technology, which many view as a delaying tactic until IPv6 becomes more common place, is not without its problems and could cause a number of popular services to fail (e.g. XBox Live, PlayStation Network, FTP hosting etc.). The prospect of a new style of two tier internet could be just around the corner."

Submission + - NASA team pushing towards thermal nuclear propulsion systems (gizmag.com)

cylonlover writes: Nuclear-powered rocket engines are not new. In the 1960s, both the U.S. and the Soviet Union developed and tested thermal nuclear rockets fitted with flight-worthy components. However, Project Rover and NERVA (Nuclear Engine for Nuclear Rocket Application) programs were defunded in the early 1970s just before test flights were to start. Now, as part of the Advanced Exploration Systems program at NASA, the Nuclear Cryogenic Propulsion Stage team is tackling a three-year project to demonstrate the viability of and to evaluate materials for thermal nuclear propulsion systems for use in future deep space missions.

Comment Not Really That Difficult (Score 1) 172

This really isn't that difficult and you can do it on the cheap if wireless isn't critical to your small business. Just buy 1 wired router with a built in DHCP server, and 4 or 5 wireless ones. Unless you need them to be powered by PoE, I wouldn't bother with the Cisco Aironet APs, just buy some cheap Linksys/Cisco wireless routers. Once you have all that, setup your wired router to connect to your network and then configure the wireless routers in the following way:

1. Disable the WAN/Internet interface on each one, you won't need it.
2. Give each one a static IP inside your network on the LAN interface (for example: 192.168.1.200 - 192.168.1.205) with a gateway equal to the LAN IP of your wired router (for example: 192.168.1.1).
3. Set each wireless router to have the same SSID, encryption, password and channel (disable automatic channel selection).
4. Connect one of the LAN interfaces on each wireless router back to your network.

Because all your APs have the same SSID and password, the wireless clients should automatically connect to the one with the strongest signal strength. Your connection may temporarily drop if you are downloading a file and start walking across the office but for most people this solution should work. If you require monitoring, use a ping script or network monitoring tool to make sure all the APs are up. PRTG is actually free for less than 10 sensors so I'd recommend that if you don't already have one.

Damn right. I'm reading some of these stories on here and I can't believe how bad it is in some companies. Every year I get 20 vacation days, 5 flex days (to be used for vacation/dentist/sick/child sick days) days and 15 sick days (that can only be used when you are sick). I also live in Canada so going to the doctor when I get someone really bad doesn't cost me anything extra.

I'll take some of the union-induced laziness exhibited by some of my coworkers in exchange for the power of collective bargaining any day of the week.

We've had these signs for a decade in BC. The problem is that some people actually speed up when the warning lights start flashing. Basically all it has done is give people a heads up that they need to start accelerating now if they want to make the light up ahead. The end result is people speeding through the intersection far faster than they would be if they had just run the amber light.

Where I live the law specifically exempts on-duty policy officers from the talking on the cell phone while driving restriction. There is no language in there saying that the phone call has to be business related either. This caused a bit of an uproar when the law was introduced...but of course it went through anyway.

Submission + - Hostess is Going Out of Business (wsj.com) 2

Apparently unable to negotiate a contract with it's 18,500+ employees, the company has decided to halt all manufacturing and close it's doors for good. If you are one of the people that still eats Twinkies, HoHos or DingDongs then you might want to hit your local convenience store and stock up now!

Comment Microsoft is a Gold Sponsor for Everything (Score 1) 134

I don't even think Microsoft looks at the events they sponsor. I can't tell you how many tech events I've been to where Microsoft was listed as a "Gold" sponsor. The last few were small ones in a 100 person conference room and nobody from Microsoft was even there. They just paid the x number of dollars to get their name listed as a sponsor for the event. What is $20,000 to a company that charges $30,000 for a single-processor edition of SQL Server 2008 Enterprise?

Ok, so what would happen if there were no default option. Before people could use the browser, a box would pop up on first run and ask the users if they wanted to be tracked or not. How many people do you think would choose to allow it? My guess would be a number near zero so I'm all for Microsoft streamlining this process and just turning it off by default. If you really want to be tracked just go ahead and turn it on.

Of course, I don't actually use IE myself, but I appreciate the effort on behalf of my parents, aunts, uncles, etc.

Submission + - Samsung Sends Free Galaxy SIII to Dragon Doodler (theglobeandmail.com)

beerdragoon writes: A Canadian man received a one of a kind, customized Galaxy SIII from Samsung. How? He sent them a drawing of a dragon he made and asked for a new phone in return. The Samsung social media team responded instead by sending him a drawing of a kangaroo riding a unicorn. The exchange generated a lot of attention and as a way of saying thank you, Samsung provided a shiny new SIII, customized with the drawing of his dragon.

Submission + - A Sasquatch Impersonator Was Killed By Teenage Girls 2

derekmead writes: Randy Lee Tenley, a 44-year old resident of Kalispell, Montana, was killed Sunday night while trying to impersonate a sasquatch.

According to authorities, Tenley was strolling along a Montana highway wearing a ghillie suit at night. Now, the whole point of camouflage is to not be seen, so it comes as no surprise that as Tenley wandered about on the highway, he was struck first by a 15-year old girl, and then again by a 17-year old girl in another car.

But why would Tenley be wandering about in the ghillie suit in the first place? Well, according to friends, he wanted to get someone to call 911 to report that Bigfoot was on the loose. As you might expect, authorities think alcohol may have been a factor. NBC Montana has video from the scene.

Submission + - Study: Marijuana Use in Teens Correlates to Decreasing IQ (bbc.co.uk)

retroworks writes: "The BBC covers a paper published in the USA Proceedings of the National Academy of Sciences showing a correlation between persistent, regular cannabis use and risk of lower IQ. The study finds the risk particularly correlates use of cannabis by teenagers who use the drug "four times a week year after year." The more people smoked, the greater the loss in IQ. Reviewers of the study at King's College Institute of Psychiatry states that the data and methodology are exceptional, but she also cautions that there may be another explanation, such as depression, which could lower IQ while stimulating marijuana use. The study does not mention or rule out "nocebo" effects, i.e. just feeling stupid for spending your teens hanging out with potheads."
