  1. Learning New Languages on One Step Toward a Babel Fish: Real-Time Voice Translation For Phones · · Score: 1

    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.

    Technical:
    - 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.

    Cultural:
    - 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.

  3. Re:All Phones Ship Unlocked on Verizon-Branded iPhone 5 Ships Unlocked, Works With Other Networks · · Score: 1

    In Europe it is common for people to get contracts to just subsidise the phone, but not the data and calls. You often hear people saying "I've bought my high-end phone for 50 Euros", but then pay 20 Euros per month on 24 hour contract, and 40 cents/minute and 20c/SMS. So it is not like in the US that you only get a full package. You can also get full packages in Europe, but once again this is not the rule.

    A more economical approach at the moment, at least in Germany, is to buy your own phone at full price and use pre-paid. It is funny, but pre-paid is way cheaper than the contracts and you are not tight to a carrier for two years. This is for me crucial because ALL carriers claim that you can't use your phone for VoIP, and sometimes even for IM. None of them block them that I know (I think the European Laws would hunt them), but I don't wanna have my Whatsapp block one day and be stucked with 12 more months to go.

    You can also get pretty good deals for full packages through your employer. If you can live with 24 month contracts, these are sometimes better then pre-paid+full priced phone deals.

  9. exactly! on The Problems With Online Math Classes · · Score: 5, Insightful

    Mod parent up, he's key on. I remember an issue with a professor in one of my C++ classes, which happened to include a large programming project. The project took about four weeks of intensive programming, and I was really proud of the quality of my code, comments, structure, etc. Only problem was that in one section we had to determine the actual type of an object using dynamic_cast after having received a base type object. We had like 10 derived objects and I've used copy paste to make life easier, but forgot to modify one entry with the appropriate type. That is, ONE word was wrong. My mistake failed in one of their tests (which I didn't have in advance), which cascaded four output missmatches. This ONE word cost me 40 points out of 100, ending up with a D for this project. One word, lots of effort. I've talked to the professor and his answer was a lame "if I fix your grade, I need to fix everyone's".

    When I was a TA during grad school, I always looked at the work flow. If a student made a mistake in part (a) of a problem, I didn't simply give him zero points for parts (b) (c) and (d) that used it as a base. Instead, I've assumed that part (a) was right and looked at the process. It took me more time to grade, sure. But it is fair and if a teacher can't contribute with some human touch, let's just replace them with computers.

  10. Don't blame Navteq on How Satnav Maps Are Made · · Score: 3, Interesting

    Natvteq has actually very good maps, particularly in Europe. The reason why your map looks bad is most likely due to your particular gear vendor. Garmin, Becker, Blaupunkt, Falk, etc. they buy maps from Navteq or Teleatlas, and they compile it for whatever their main goal and budget. In order to reduce the map size and save money, they compress the data using a battery of techniques. One common technique is decimation, where they simply remove geometry points to save space, leaving mostly the ones that represent intersections and a few in the middle. POI suffer as well.

    So please don't be too fast in blaming a map vendor, where the fault is almost certainly from your navigation system vendor.

And the interface is much less cluttered, I can quit the app without having to read a manual, no ads, really slick.

    I haven't looked at the new Skyp 4 yet, but I don't find it unlikely that I switch back to the old version at some point. One nice thing about Skype being so closed and proprietary is that the chances of seeing a Linux exploit based on Skype are extremely low.

  14. Re:Let's distinguish here on TomTom Flames OpenStreetMap · · Score: 1

    Absolutely correct. OSM accuracy is very good, indeed. The only "problem" with it is that it's a best effort, and it doesn't have a standard way of doing it. For example, when you trace a 4-lane highway, on which lane do you collect the data? If you cut a curve when driving on the mountains, how do you deal with it later? How do you decide where to place your shapepoints so that the error in the true curvature is below the required threshold? There are guidelines, and people should follow them. But if they don't so be it. Commercial map vendors do this for living and must follow their data-collection procedures, which are very well documented.

    For many applications, OSM is awesome. But there is a group of applications, and I can only speak about the automotive sector, where paying for commercial maps is still worth it. Of course I don't mean navigation, where OSM is already good enough.

  15. Re:Let's distinguish here on TomTom Flames OpenStreetMap · · Score: 1

    this is because the map you have on your navigation system has been optimized for navigation and highly compressed. You don't need this high accuracy for navigation. But if you bought the maps from Navteq or Teleatlas directly, you'd see that the accuracy is much better. Remember: maps is *not* just navigation. There are literally hundreds if not thousands of other applications that can benefit from digital maps.

  16. Re:Let's distinguish here on TomTom Flames OpenStreetMap · · Score: 1

    This is a nice guess and usually works, but it is not guaranteed to give you 1m relative quality. You can have systematic errors that apply to all users that traveled the road that day, such as bad weather or ionosphere effects. But another problem is that users drive by car using particular patterns that do not necessarily match the true road geometry. Some examples of these are curve-cutting when driving, lane changes on highways, etc.

    The approach you are describing would require more than 25 people and as a matter of fact, this is what Teleatlas (Tom Tom) does with their shared data. Nevertheless, it is a statistical best guess, and the method shall not be compared with a trace collected via DGPS. They are fundamentally different.

  17. Let's distinguish here on TomTom Flames OpenStreetMap · · Score: 5, Interesting

    I have been working with digital map data for on advanced driver assistance applications for a few years, and my experience is the following:

    Some applications want lots of data. They don’t care if it is perfect or not, such as whether there is a zebra crossing, a traffic light, a stair, a path for mountain bike but not for road bike, etc. One example of this is navigation: it doesn’t matter if the turn has an error of 10 meter, if it is 10 or 25 degrees to the right, etc.

    Other applications they are fine with less data, but this must be absolutely accurate to within a meter. Examples of this are active-safety applications, such as map-based adaptive front lighting, curve warning, etc.

    Some other applications are in the middle. They are not very sensitive, but annoying if incorrect: example of this is speed limit warning.

    The biggest map vendors collect hundreds of attributes at very high quality. This is true particularly for low-number functional classes (highways and motorways). They often meet the 5-m absolute and 1-m relative accuracy for geometry.

    It is very difficult for OSM to meet this high quality, specially because you need a differential GPS (DGPS) to collect these. That said, map vendors invest most of their effort on large important roads, while rural or off-roads have from low to very poor quality.

    Moreover, one thing is the quality at which data is collected, and another one is the map quality. Vendors tend to decimate (strip-out) geometry points on non important roads in order to reduce the size of the map.

    So to sum up: if you are on a motorway or highway, OSM probably won’t match the quality of Navteq, Teleatlas or Google. If you are on a rural area, off-road, bike trail, etc., OSM will probably kick everyone’s butt. Plus it is usually more up-to-date.

    TomTom tries to close this gap with their community content, which I find very dishonest from them. They save millions by using people’s data, but they don’t pass these savings back to the consumer.
