I mean, there's a security flaw in the Siemens S7. Now let's all take a wild guess what the Chinese copied.

I'd say that there are flaws in just about every major PLC (Allen-Bradley, Modicon, GE, and so on, to name a few) . Most are just legacy serial protocols that have been wrapped in Ethernet, so these controllers accept arbitrary packets from any source. With protocols like MODBUS, it is fairly easy to construct such packets by hand even.

EA Shuts Down Pandemic Studios, Cuts 200 Jobs 161

Posted by Soulskill
from the say-goodnight-folks dept.
lbalbalba writes "Electronic Arts is shutting down its Westwood-based game developer Pandemic Studios just two years after acquiring it, putting nearly 200 people out of work. 'The struggling video game publisher informed employees Tuesday morning that it was closing the studio as part of a recently announced plan to eliminate 1,500 jobs, or 16% of its global workforce. Pandemic has about 220 employees, but an EA spokesman said that a core team, estimated by two people close to the studio to be about 25, will be integrated into the publisher's other Los Angeles studio, in Playa Vista.' An ex-developer for Pandemic attributed the studio's struggles to poor decisions from the management."

I'm not aware of any that do? Off the top of my head I can think of CIP, Modbus, Ethernet/IP, Profibus, ProfiNET, DeviceNet, and CANOpen and none of these have any authentication. At best, some of these like CIP have security through obscurity, but others like Modbus are completely known specifications.

I concur. Airports are the same way, and still this way. Many are running standard PLCs like Allen-Bradley or Modicon. They are connected directly to a modem line with no authentication. So grab yourself a copy of RSLogix or Unity Pro, dial into these places, and have fun modifying the ladder logic and wreak havoc on the airport as all bags get re-routed to who knows where. I've seen the same issues with power plants and water treatment facilities.

The only upside is that the modem line isn't hooked up all the time these days. It's usually just when they need someone to dial in, and then a worker at the facility will go and hook up the line.

In May, I'll have completed my Master's degree entirely online through NC State's Engineering Online program. Since most people have already mentioned the negative aspects of online classes, I'll mention some of the positives.

First, it's incredibly nice to be able to rewind, pause, and replay portions of a lecture. It's also very useful to be able to play older lectures. And, it's nice to be able to watch lectures when it is convenient for you, especially if you are working full-time.

The lack of direct communication during class is easily mitigated by having an online, voice enabled office hours system. Most people don't show up for a professors' office hours, period.

Certainly, I don't think online courses can be applied to all classes, but from my undergraduate experience, many of my science/engineering courses were simply large auditorium lecture halls with little to no interaction anyway. So there goes class participation.

Some people might mention the lack of personal networking. Quite the opposite, I've met more full-time employees at other companies who are also in a distance program than I ever did in my undergrad, where I was mostly networking with other jobless, inexperienced students. If anything, I've observed that the distance students, being full time, tend to have higher averages as a whole than the 'live' classroom sections, mainly because most of us have years of practical experience in the field under our belts.

So, all in all, do classroom learning if you can, but for many classes, you won't really get any benefit.

It's one thing to tell someone that they're no longer welcome to order anymore, but it's quite another to retroactively disable anything that they've previously purchased. That's the distinction.

Many people abuse the flexible Costco return policy. Some of these people get their memberships revoked. At no time does Costco come in and say that they can no longer use items they've already bought.

Facebook Cuts Off Pirate Bay Links 137

Posted by CmdrTaco
from the hyperlinks-are-bad-mmm-kay dept.
narramissic writes "Citing legal reasons, Facebook has ended its brief relationship with The Pirate Bay. The Pirate Bay added a 'Share on Facebook' button around two weeks ago to its site that allowed its users to post links to small information files on Facebook that are used to download audio, video, etc. via BitTorrent. Facebook is now blocking those 'bookmarklets' as well as any links from The Pirate Bay, said Peter Sunde, of The Pirate Bay. Sunde said he received an e-mail from Facebook justifying the action because of the legal proceedings against Sunde and three others. The men are awaiting return of a verdict on April 17 from a trial that concluded early last month in Stockholm. They are charged with helping to make available material under copyright."
