I wish I had points to mod parent up. I couldn't have summarized this better. Kudos for doing it in such a respectful way.
Although your post is informative and accurate, I think you are slightly missing the whole picture of what the parent poster was trying to convey. As far as cellphone technology is concerned, the US is indeed in the 90's. Not just due to locking, but in many other different aspects as well.
call price model:
- the US is about the only country in the world where the recipient pays for incoming calls when not roaming. I leave it as an exercise to the read to think why this is plain ridiculous.
- the prices are plain crazy. In Europe you pay max 30-50 Euros per month for unlimited plan, with 1GB or data. Less if you don't need unlimited. I payed about 15 Euro/month for moderate calling and 1GB/month, with the option to purchase on-the-fly 1GB extra for additional 3 Euros if you run out.
- in the US, if you exceed your limit, you get a heavy bill. In Europe, your data speed simply decreases down to GPRS.
- the US has many many dead areas. I know, it is a big country. But the fact remains.
- incredibly intrusive branding, crapware, etc
- carriers are involved in certifying which phones are supported in their networks, the software update process, etc. which is none of their f*ing business.
- they use non-compatible networks.
- Their customer service is such crap that I don't know where to start.
All in all, this puts the US model of cellular communication really in the 90s. The unlock issue is just the cream on the top.
Since most people don't have a clue about audio and just follow marketing trends, you are probably right on spot. Now most of us here in Slashdot should know that noise cancelling headphones only knock out low frequency noise, like the engines. Conversations don't get cancelled at all. All the contrary, quite often you can hear them better when wearing such headphones, because the sound of the engines don't stay in-between.
For a better cancellation use noise isolating (passive) the in-ear earphones with foam tips, like the ones from Shure, westone, etymotic research, etc. They'll cut out a lot more than noise cancelling headphones, and they sound a lot better.
Wait until this legislation is approved, and measure again in 5 years whether gun point mugging has been reduced. Problem is, hackers and criminals will find overnight a way to circumvent this protection. So in the end, we won't be able to measure anything.
You are correct. Particularly dead reckoning based on stars has been used for centuries for navigating across oceans. I was referring mainly to computer-based dead reckoning, which involves quantifying the error of your estimation based on a mathematical model, and how modern dead reckoning works.
Most cars have a high speed CAN, for all functions needing messages at a rate of about 10 or 20 ms like Abs, engine, etc. There is also a low speed CAN, which is used for things like heating, and low rate signals of about 100 and 200 ms. The advantage of low speed CAN is that it can be put into low power and use it to wake up devices, like a wake up on LAN. I Then there is the LIN bus. This is a low speed, single wire cheap bus. It is used for things like wipers. These are the basic three buses.
Cars like BMW and Mercedes have two or three high speed CAN, a MOST bus for entertainment, and a flexray for safety critical applications. Other manufacturers use TTP instead of flexray, but the safety and timing is in both cases the main reason for not using CAN throughout.
Cars are also slowly rolling out Ethernet, mostly due to the high speed and low cost.
All buses are connected to each other in one way or the other via dedicated gateways. These gateways are usually not pure network gateways, but standard ECUs used for vehicle functions, also serving as gateways.
Then there are internal buses. For example some controllers include multiple ECUs connected via SPI or similar. The engine ECU is almost always connected to the CAN bus because it requires a lot of information from other systems, such as speed, gas pedal input, etc. The actual firing of the sparks is very time critical, and this is after done via a dedicated TPU controller, integrated as a sub core in the engine ECU (take a look at the MPC555 documentation), connected to the main ECU via an internal bus.
The point is that no one gives a Shit if you Fuck up your car by plugging something to one of the vehicle buses. From the OEM perspective, the car must be non hackable from the outside, but once you are in, it's your problem.
I spend a little more, I can get a full CAN-bus connection and actually *send* information and control things.
No, you can't send over CAN this way, at least not without risking messing up the core structure of your network. Most nodes in vehicle CAN send messages periodically. Each message type has a unique id, and sending two messages with the same id at the same time can result in collisions. But even if these don't collide, they will get overwritten right after by the next real message. If the inconsistencies are bad enough, the safety fuses will catch them and shut the system down. Any respected automotive OEM implements such mechanisms. I In CAN it's not possible to intercept messages and perform a MIM attack, unless you hack into a gateway like LIN or flexray to CAN.
I work with for the automobile industry and quite honestly, I'm sick of reading this type of articles where people gain physical access to the OBD or vehicle bus, including the respective network databases, and claim to have hacked a car. It is like saying that a house is insecure because you can break into it, turn on the stove, and cause a fire with it.
If you can hack the car from the outside, give me a call. But don't pretend to be a hacker by exploiting things that were never meant to be protected. We are encoding things that we care about and if the CAN is not encoded, is because we don't care about you fucking up the bus communication. On the contrary, we will most likely end up crashing your car and buying a new one.
Dead reckoning technology is actually very old. It has been used to guide missiles, submarines, and of course cars for decades even before the GPS was invented. It is the technology used by sailors before they had GPS as well. The idea is simple and complex at the same time: use some specific known reference, guess what's happening in the absence of reference, and recalibrate once a new reference becomes available again . References can be the sun, stars, towns, or GPS itself.
In car dead reckoning, in contrary to what the article says, you typically don't use acceleration sensors. You typically use vehicle speed and yaw rate sensor. This gives you enough information to determine whether you've turned, and where you are along the road. If you can safely assume that you are following the road on your digital map, this is actually quite accurate. It becomes tricky if you are airborne and free to fly around, but also possible.
The nice thing about GPS is that the kalman filter used to compute your position and velocity can be easily extended to include additional sensors such as yaw rate and speed, available on any modern vehicles CAN bus. The only trick is to have the navigation system hooked into the vehicle, and this is one of the main advantage of built-in systems (the other being driver assistance functions taking advantage of map data for enhanced functionality)
I think there were some navigation systems manufactures trying to achieve similar results by adding accelerometers to the receivers. Since people usually use these devices to follow a guided route, a yaw rate sensor to detect turns is not essential, and detecting stop conditions in urban canyons or tunnels can be detected via accelerometers.
The possibilities are endless and they have been used forever in the navigation industry. The article is extremely misleading by claiming that this is new, or hasn't been done before. Nevertheless a cool technology.
With all respect, I don't want to stop hearing these news. Because I want *confirmation* of every single thing that the US has done against people's freedom. I don't want to be considered a tinfoil hat paranoid anymore. I want proof, so no one can neglect later, about how fascist he US has become. And just because it was suspected, it doesn't mean that it is ok and we can just keep going with our lives as if nothing had happened. I want to see people resign, and I want to see people get spit at publicly, and ideally --even if it's never gonna happen-- I'd like to see people going to jail not only for having violated the most basic human rights, but for trying to brainwash the uneducated into believing that this is the correct approach to protect US's national security.
Seriously. On a 501-day trip, intercourse will happen at some point. If it gets too wild, she could get pregnant. And having a baby in the middle of such a mission will be a major catastrophee. They should really make sure that the two humans in this mission are sterile. I don't see it worth of taking any chances.

Belkin says it really sucks to have to maintain the Linksys brand and offer support for Linksys products, but the law requires this at least for the guarantee period, so they will have to comply. What happens afterward is, as always, not a topic for a spokeperson. That would be something worth saying, and it's against the rules of a spokeperson, who never say anything useful or that we don't know already."
Make sure to play a game where she can buy add-ons using her credit card, do on-line shopping, and dress up figures like Miis or something.
I've stopped going to theaters the day that a single ticket (in Germany where I live) starting costing 9 Euros. About 15 Euros if the movie lasts more than two and half hours. All was in favour for home theater, which was more comfortable, cheaper, and convenient. But when my old big CRT screen died two years ago, I also stopped watching movies and TV at home altogether. Why?
- DVD are not HD. Blue rays cost about 25 Euros in Germany. All with the classical FBI don't pirate message crap and unskippable commercials for old movies, as a mean of thanking you for buying the film
- Open channels suck really big time. It is basically Christian TV and buy-your-crappy-as-seen-on-TV channels
- Cable TV already charges you for non-HD crap. If you want, then pay more for HD crap
- Things start to become watchable after folding about 50-60 Euros per month. But you need to use *their* receiver if you want to record movies that you can keep for just one day. Have fun with 3 remote controls by you couch, and explaining your wife *every time* how to use it, while she laughs at you. Oh, and you can't skip commercials for the *paid* channels.
- Pay more if you want 3D movies.
- Google Movies: in Germany, they cost like a DVD and *only* come with German tone. So let me get this straight: Google sells you something that cost as a 10-year old technology. They benefit from the digital era by cutting cost, but they don't transfer a single cent to you. In return, they give you a cripple experience much worse than the old one. No original tone, no subtitles, no director comments, and usually worse quality. No thanks.
In short, I'm sick of these new technologies that are only meant to give more profits to media producers, and they don't care at all about what the customer wants. I vote with my money, by not having a TV anymore, and spending more time outside with my family. It was tough for the first 6 months, but now I don't miss it at all, really. And my kids don't even know what they are *missing*.
This explains why SAP is such a horrendous piece of crap. And if you are gonna say that I'm trolling, please first go and use it yourself.
My request to this asshole: please get someone *above* 40, someone with more than 20 years of experience behind his back in GUI design and software ergonomics and code optimization, so that he can fix what your cheap workforce has pulled out of its butt.
Anyone who believes that machines can replace learning a language has clearly never left his country or spent more than a week abroad. There are technical and cultural issues that render such statements nonsense.
- you need to speak like another machine for these systems to recognize what you say. Start putting some accent (like the different Latin-Spanish versions), or dialects (like in Germany or China), slang, and the model breaks quickly.
- no system is able to mix languages. And you need this. It is common to mix languages with certain words, street names, person names, etc. from other languages.
- street language. Even if the sound recognition were perfect, no machine translator can possibly translate what you hear on the street.
- go to a sales meeting and you are trying to sell your business services to a customer using your voice as translation. Your competitor speaks the language fluently, using idioms and other tricks. Guess who gets the deal.
- pick-up a girl in Italy using a phone/voice translation and I will aplaud you.
- attend university abroad using your tech-device.
- tell a Joke to your phone, hoping that its translation will make your foreign friends laugh.
the list is endless. So is this a good invention? Yes. Will it work? Maybe in the future for some limited purposes. Will it replace learning languages? Heck no.
