Comment: Network Coding (Score 1) 129

I remember working on a project where network coding was proposed for micro satellite cluster communications. If I remember correctly, network coding requires that all the nodes in the network have complete knowledge of the state of the network at any given transmission window. This requires transmission of the network state which used something like 7% overhead. The routing of a message from one end of the cluster to the other was difficult. I believe it might have been an np-complete problem. Have they solved the routing issues?

+ - Curved Smartphone Screens Aren't a Gimmick->

Boycott BMG (1147385) writes "Recent discussion on /. about the Samsung and LG curved displays seems to dismiss them as mostly gimmicks, but in an article at Displaymate Dr. Raymond Soniera explains one of the advantages of curved displays: altering the reflections. From the article:

Reflections from a Curved Screen

The concave screen shape on the Galaxy Round cuts down on reflections from the surrounding ambient light two ways: first, by reducing the screen’s 180 degree opening angle, which eliminates reflections from some ambient light coming from the sides. Second, from specular mirror reflections off the concave screen, because the curvature directs reflected ambient light coming from behind away from the viewer’s line of sight. This is very important because you want to minimize the amount of ambient light that is seen reflected off the screen.

Curved Screen Magnification

But the most interesting and important result of the slightly curved Galaxy Round screen is that it magnifies the sizes of all of the objects that it reflects, just like a concave mirror that I mentioned above. As it turns out, that substantially cuts down on the interference of light reflections from ambient light in three ways:

I don't know what genre of game the submitter plays, but for fighting games, which I play, input latency can mean the difference between winning and losing. 50ms is 3 frames of lag, which means you need to react 3 frames faster to an overhead or throw. This wouldn't be a problem if everyone used the same equipment, ie PlayStation controller, but if someone had a controller that somehow had lower latency than the regular controllers then everyone who wants to compete would flock to it.

Not only that, but it lacks the features to exploit. Which is actually an important point in security, to only have the features you need and nothing else. Less surface area to attack.

Pretty much any software that is sufficiently complicated will have security bugs.

The current slowdown in PC sales started well before Windows 8 was released to the public and oems. As someone who holds a little bit of money in AMD stocks, I followed their press releases and they were claiming some slowdown in spring of 2012. If you look at Intel's financials, they were also experiencing an inventory buildup of the latest and greatest ivy bridge CPUs and had to idle more 22nm fabs than usual just to keep their margins and income up. http://www.anandtech.com/show/6378/intel-q312-earnings-3-billion-profit-on-weakening-market-intel-to-idle-some-fab-capacity

The fact is that smartphones and tablets have replaced PC notebooks for some tasks like email, calendar/scheduling, and instant messaging. If a certain percentage of the population used a PC primarily for those things then they might delay upgrading their PC and instead get a smartphone.

I appreciate the suggestion but I very much remain dubious they will get it "right". While I don't have anything against those features they are superfluous. Someone needs to get drawing and note taking right. It should work very much like writing on a paper note pad and be very easy to use. Every pen implementation I've seen so far gets carried away with handwriting recognition and other theoretically nifty features (which rarely work very well) but don't make just writing/drawing easy which is the bit that actually matters. It's more important that *I* be able to write and recognize what I wrote than the computer. I remain hopeful but so far every attempt I've seen has fallen badly short.

In fact, the note series does let you just scribble or doodle or whatever. The handwriting and formulae recognition is a feature you need to tap to activate.

You may be looking for the galaxy note series from samsung. The whole series (note 1, note 2, note 10.1, note 8) have features like formula match, which reads your handwritten equations and tries to guess what the formula was, shape match for diagrams, and handwriting recognition.

The hardware part was done by a 3rd party, but the software to do the skeleton tracking and other things was all done by Microsoft. Basically the hardware combined a regular camera with an IR camera in an intelligent way to do range imaging. To get from just the camera to what you have with Kinect takes an awful lot of intelligent algorithms. I think that qualifies as innovative.

The use cases would be: 1. People who like fitness bands, will likely appreciate the tighter integration that would come from using a smart watch and smart phone from the same manufacture. 2. People who get a lot of notifications, (texts, calls they might not answer, calendar events, etc.) will be able to determine if the notification requires immediate attention without the disruption of pulling out their phone. 3. Combined with a headset allows you to operate your phone and music without needing voice control or to take out your phone. 4. makes checking the time slightly quicker.

All of those things have already been implemented by the current crop of smartwatches, although I don't think there is one that implements all 4 points at the same time. Motoactv does (1) and (3), Sony Smartwatch does (2) and (3), and Metawatch does (2), (3), and (4).

Interestingly, smoking, but not drinking, is one of the things that insurance companies will still be allowed to discriminate on in the Affordable Care Act. So if you are a boozehound they can't increase your rates but if you are a smoker then they can charge you more. The other things that can still affect your rates are your age, whether you are married w children, and what area of the country you live.
