Software Bug Behind Biggest Telephony Outage In US History (bleepingcomputer.com) 106

An anonymous reader writes: A software bug in a telecom provider's phone number blacklisting system caused the largest telephony outage in US history, according to a report released by the US Federal Communications Commission (FCC) at the start of the month. The telco is Level 3, now part of CenturyLink, and the outage took place on October 4, 2016.

According to the FCC's investigation, the outage began after a Level 3 employee entered phone numbers suspected of malicious activity in the company's network management software. The employee wanted to block incoming phone calls from these numbers and had entered each number in fields provided by the software's GUI. The problem arose when the Level 3 technician left a field empty, without entering a number. Unbeknownst to the employee, the buggy software didn't ignore the empty field, like most software does, but instead viewed the empty space as a "wildcard" character. As soon as the technician submitted his input, Level 3's network began blocking all incoming and outgoing telephone calls — over 111 million in total.

Submission + - Google Testing Software to Judge Hollywood and TV's Portrayal of Women 1

theodp writes: Aside from it being hosted in a town without a movie theater, the 2016 Bentonville Film Festival was also unusual in that it required all entrants to submit "film scripts and downloadable versions of the film" for judgment by "the team at Google and USC", apparently part of a larger Google-funded research project with USC Engineering "to develop a computer science tool that could quickly and efficiently assess how women are represented in films" (an award for "Highest Diversity Score" was awarded at the film fest, fittingly to the film 'Tested'). Fest reports noted that representatives of Google and the White House Office of Science and Technology Policy appeared in a "Reel vs. Real Diversity" panel presentation at the fest, where the importance of diversity and science to President Obama was discussed, and the lack of qualified people to fill 500,000 U.S. tech jobs was blamed in part on how STEM careers have been presented in film and television. White House Visitor Records show that in the weeks leading up to the festival, representatives of the Bentonville Film Fest and Google met at the White House with scores of female educators, advocates, and activists from universities and nonprofits, as well as execs from the toy, game, film, television, print, and retail industry. In a 2015 report on a Google-sponsored USC Viterbi School of Engineering MacGuyver-themed event to promote women in engineering, USC reported that President Obama was kept briefed on efforts to challenge media's stereotypical portrayals of women. As for its own track record, Google recently updated its Diversity page, boasting that "21% of new hires in 2015 were women in tech, compared to 19% of our current population," although its most recently posted EEO-1 report showing actual headcount is still from a pay period in 2014.

Comment Re:Electric delivery trucks have a great future (Score 1) 223

I think range is still a limit for most. I live in the Washington, DC metro area. WMATA (the regional transit provider) runs mostly hybrid diesel and CNG buses. They have found that while CNG is cheaper on a per mile basis just concerning fuel cost, most of the CNG buses can't handle a double shift on one fill of CNG so they end up having a lower percent utilization than a diesel since they have to head back to the garage for a long refill after each driver's shift. Their CNG buses typically fill overnight as they take several hours to fill. A diesel takes minutes to fill, so even with the same range per fill, a diesel can run nearly continuously. Not all the WMATA garages support CNG and plans to build CNG infrastructure at more of their garages have gone slower than originally planned and my understanding is the primary reason is the operational constraints of CNG fueling.

Electric vehicles currently have the same kind of limitations as CNG. Without expensive infrastructure for doing things like en route charging, a bus needs to be able to comfortably run two shifts back to back before a transit authority can use them on a wide scale - probably roughly a 300 mile city range. The charging infrastructure even in a garage is expensive. Swapping enough batteries for a 300 mile bus range is also labor intensive. I agree that electric makes sense here, but the infrastructure just isn't there yet.

Van based trucks (think UPS) are light enough that they're not that hard to electrify from today's standards. However a medium duty truck like a box truck gets roughly the same kind of fuel economy as a transit bus and so the amount of energy you have to carry to make them work well today is still expensive and hard to do.

And many people beat the crap out of rental cars. I've rented cars numerous times that I start up and they say "Next oil change due: Immediately", which I then proceed to drive for a week and put 3000 miles on it. I've never had a rental car break down on me, but the evidence has generally been that they're not well maintained and they get away with it because the cars are relatively new. Many people also drive rental cars like they're stolen. Buying one seems like a bad deal to me.

Comment Re:It works differently in (most of) EU (Score 2) 439

You can custom order a car in the US. I've done it, and based on my experience, will do it again next time I want a new car. I got exactly the options I wanted without getting stuck paying for stuff I don't want or would never use. In my case, I ordered before the production began, so I waited 3 months for my car, but for most models already in production, the turnaround is usually 4-6 weeks.

Granted, you can get some good deals on cars that are just sitting and therefore have been marked down (you have more negotiating power there), but in my case, getting exactly what I wanted was more important - and I bought through Costco (still uses a dealership but the pricing is prenegotiated). Since I was buying a brand new model, the Costco pricing killed whatever I could have negotiated on my own, but YMMV on models that have been out for a while.

Comment Re:Shit. (Score 4, Interesting) 411

It's probably how VW got a Euro spec engine to meet US regulations. Euro specs measure pollution per distance - the way to win is to burn fuel really efficiently. US specs measure pollution per unit of fuel consumption - the way to win is to burn fuel really cleanly. That difference is a big reason why they have much more fuel efficient vehicles in Europe. It's much easier to get a larger engine to burn cleaner. Most manufacturers that sell the same engine in both continents use different tunings in each, where the EU one gets better fuel economy and the US one burns cleaner.

Manufacturers have been trying to bring the incredible economy that small diesels in Europe get to the US for years but it turns out making a diesel that is significantly more efficient than a comparable gas engine and also meets EPA regulations is really hard. For example, Mazda has been promising Skyactiv-D (diesel) engines in the US for years now, but they keep getting delayed because they're not satisfied with their performance.

Comment Re:MOOCs: my worst education experiences ever. (Score 3, Interesting) 46

I don't have experience with Corsera courses, but I am currently an OMSCS student at Georgia Tech (http://www.omscs.gatech.edu/). So far, the lessons (YouTube videos through Udacity) have been well done. However, the course discussions on the forums (Piazza) in some cases have been more valuable than the courses themselves. In particular, we've had a great thread going on about real world agile vs. non-agile development models as we've seen them in the professional world.

The difference may be that while not all students are US based, all students have to apply for admission to the program, with minimum credentials being a BS degree (generally in a STEM field) with a 3.0 and TOEFL scores for non-native speakers. Students are expecting rigorous courses and are generally graded at least a little bit on forum participation, so students have incentives to participate and the faculty and other students don't put up with "give me the answers" type posts (those would be an honor code violation and could easily get you kicked out). Maybe having to be admitted to a real school makes all the difference?

Comment Re:Police unions will kill it (Score 3, Insightful) 151

I have worked with automated vehicle locator data throughout the US as a source of data integrated into my company's products. Getting a fire department's AVL data is easy. Never had any objections if they have the hardware installed. Getting police AVL data is next to impossible in most places thanks to the union agreements. I am unaware of a single US police department that has AVL on by default for their vehicles. Those that have AVL systems installed have it configured so the officer can turn it on and off, usually at the flip of a switch on the dashboard.

It's such an issue with the unions that we've had trouble with getting some departments to have AVL enabled in the police cruisers leading and following a parade just for the duration of the parade. It makes the command center's job much easier if they know the exact extents of where the parade is in real time, but you can figure out the information in other ways so it would seem like something that wouldn't get a lot of push back. I can't even imagine trying to get an always on system installed in a department, regardless of who you pitch it to.

Comment What's wrong with GFCI and Tamper proof outlets? (Score 2) 284

I like your thinking about possible safety avenues, but I'm not sure any of them have any real merit.

Regarding toddlers sticking metal objects into the socket, the 2008 National Electric Code calls for tamper proof outlets, which are already adopted by an overwhelming majority of states. Those are fairly cheap and prevent sticking items in one side of the socket. GFCIs have been around for quite a while that trip if it detects a slight imbalance in electric flow, sending the current through a relay which cuts the power.

I don't see how and outlet could logically not allow current t o flow if it risks overloading the circuit since it would need to have the draw first to determine that. Isn't this what circuit breakers are traditionally for? Implementing that in an outlet would seem to be like a GFCI where it trips that outlet but leaves the circuit functional. I'm pretty sure voltage would require the device to be smarter, not the outlet.

Grounding on an outlet (the third prong) is only good for protecting equipment, not people. Again, the device would be able to make that determination if its smart enough, the outlet has no practical way of enforcing that without being able to tell a smart device to actually flow current through ground and then sense it for verification. An outlet on its own can't do it, and assuming both outlets and devices were changed to support it, said device would then trip a GFCI if it wasn't plugged into one of these special outlets.

Maybe you misunderstood what I was saying.

This doesn't affect me at all. My job is production based so as long as I do what I need to do, I'm good. While there are bad weeks where I have to put in 60+ hours, a fair number are great and I only need to put in 20-30 so it balances out well. They're also good about time off and vacation so for me there aren't many worries.

I got to this position because I earned my Computer Engineering degree and work as a skilled laborer. There are many people that have jobs that are far less skilled making them more and more expendable. Some people like this are in a position where one of the only things they can get going for them is the knowledge they can be walked all over.

And you can unionize unskilled labor all you want... When it gets to pricey, it'll just be moved away like so many other jobs to governments who give even less of a f**k. Even skilled labor can run into problems if there's decent competition.

Perhaps add this episode of This American Life to your playlist to see how depressing that situation currently is. It talks about Shenzhen and not just worker rights abuses there, but human rights abuses faced by employees.

I think most people would rather not be seen as being in the bottom 50% of workers where they are for fear of layoffs or any sort of cutback.

I think most people would rather take a small increase in work-stress to forgo a lot of financial related stress down the road.

Awesome Idea - until the person beside you is using the cell network to navigate and is quietly listening to directions until the cellphone stops working.

Then distracted by the lack of directions starts messing with the phone to fix the problem getting far more distracted from the road than they already were.

Or someone who is texting every couple of minutes... instead of hanging on to the phone for a few seconds at a time they'll now probably study the phone until the text goes through... which will be far longer.

Or worst yet, someone who needs the phone for a true emergency.

Man, that sounds like it will make drivers less distracted *rolls eyes* And don't get me wrong - I don't advocate actively using your phone while driving at all, but your "solution" will at best do nothing, and at worst just create a bigger problem.
