  1. Re:Multiple versions on Encoding Video For Mobile Devices? · · Score: 2, Insightful

    For that iPhone if bandwidth is a problem for 960x640 video, you may want to look at say 480x320 resolution video. Yes it has to scale up, but I can imagine it looks better than 480p or 360p as every video pixel becomes exactly 2x2 screen pixels. Instead of having to interpolate or whatever you have to do to make it fit on a non-matching resolution, like 1.5 screen pixels per video pixel.

    From my experience with LCD screens it is the non-matching of resolutions that make them look crappy. When using the exact half resolution they look good again, as the pixels fit nicely.

    Hooking up nose down may be easier, come to think of it. Because then what you should do is basically land on top of the wire with a small forward speed, letting your aircraft slide forward until the hook mounted all the way at the tail catches the wire. Presto, hanging nose down.

    Getting off would be simple as well that way: retract the hook, fall down making speed, and just pull up the nose. Now just make sure you hang on a high enough wire.

    Taking off hanging nose up is a bit harder, I would guess a tail flip - also a quite standard manoeuvre but requires more height. Unless your engine is so powerful that you can accelerate straight up. Not likely for such a craft.

    Seeing that video I think it's indeed going to hang. There seems to be a hook at the plane's belly to hook onto the cable.

    It's a hard trick. I wonder how many tries for that video to work out - that mattress won't be there just because. And this is indoors, no wind, no movement of the wire. The wind will be the hardest: wind changes all the time, and will be influenced by the cable at close range. I can imagine quite some turbulence to overcome for the aircraft.

    I wonder how often birds have to practice before they can land on a wire. The flying, the timing, the following of the wire as it swings in the air... it's not easy. And then many birds have the advantage that they can hover, even if only for a short while, in a way a fixed wing craft can never do. The bird has a lot of time for last-moment correction, a fixed wing craft not. It falls off and will have to turn around (a tricky manoeuvre in itself, after serious stalling, nose up in the air, and probably taking a hit from the cable it tried to hook on to) and try again.

    No matter what it's an impressive trick, even in such a controlled environment.

    While there certainly are errors in the maps, recently I have been driving and having me guided by a TomTom system, and it worked great. Maybe they didn't give me the super-optimal route, but it guided me very will right through Hamburg straight to the motorway.

    Without a system like TomTom I would likely have either gotten lost trying that route, or would have opted for an easier to find but much longer (20-30 km kind of longer) detour.

    It also guided me straight to where I had to be, in both industrial and residential areas. Sometimes a little confusing (but then intersections can be confusing by design, or when they are really close together spoken instructions also don't go all too well). Just the final house number was sometimes not at the exact right spot... it got me to the neighbours instead.

    Of course when driving using satnav you have to keep your eyes on the road, and keep looking whether the suggestions are actually possible. It actually allowed me to much more concentrate on the road and the traffic than when we would have been using maps and I would have to look at the direction signs on the road while driving, instead of just listening to the tomtom for where to go.

    So for me I found it overall a plus for road safety, even though admittedly there are errors, but no map is perfect anyway.

    And about economic competitiveness: does this really matter?

    We're talking home broadband here. Recreational mostly, sometimes used for shopping but then that's primarily mail-order shopping, not much content delivery over the wire. The latter is increasing but it's still not much.

    How is faster residential broadband really making an economic difference?

    Even for most businesses it won't make too much of a difference. For me it is almost as long as I am connected it's fine (I have just 2 Mb up/down - business grade, expensive enough for a 2-man company, it doesn't slow me down in my normal course of business). Half my current speed would do. More is nicer but it doesn't make my typing faster. Sending out e-mails may go fractions of a second faster but even that is not significant any more.

    So again the question: why the focus on "economic competitiveness" for home broadband, beyond actually having it?

A car comes with maybe two years warranty, after that you can keep it running at your own expenses: you pay for "extended warranty" or simply for repairs as they come along. Though an "extended warranty" scheme, kind of insurance plan covering repairs, is surely imaginable.
    • Software doesn't come with any warranty to begin with, and that for some reason we consider normal too and fully accept - hoping for the goodness of original developer to provide fixes (preferably free of charge) for problems found along the way.

  15. Mixing up DATA and INFORMATION. on The End of Free · · Score: 2, Interesting

    So many people talking about "information wants to be free" do not seem to understand what "information" really is, and the difference with "data".

    Information wants to be free - that adagio stands, has always stood, and will always stand. The problem is that people do not know how to distinguish between data and information. The data is just a representation of information.

    Take for example this post: as soon as I posted it it becomes a piece of data on some server rented by the /. company. Just that: data. How to get to that data? You need a computer with Internet connection. Now that connection may become more expensive, getting to a web site may become more expensive (e.g. subscriptions), but the information that I give here wants to be free.

    For example the following sentence: "Spain won the world cup football 2010 by beating the Dutch team in the finals 1:0". That contains information on the world cup football. It is also a piece of data. Getting to that piece of data (the actual sentence) may become more expensive, the information in it (winner of the world cup, score) can be re-told over say the phone when someone who read this is talking to a friend. That information bit never got more expensive. It wants to be free. The information spreads because people like to talk to one another (irrelevant of the medium), and they like to tell each other things the other party didn't know yet. To discuss facts, to discuss bits and pieces of information they learnt through other channels. Such as the world cup line above - it won't be new to many people here but that's not the point. It's a bit of information that is stored in a chunk of data.

    On the other hand, data is just that. Lots of numbers, letters, whatever. An LP contains two immensely long wavy grooves, typically representing some kind of music. An mp3 file could be a digital representation of the same sound. Both are different representations of the same data, they may each not be free (cost of the record, restrictions by DRM).

    The adagio also says WANTS TO. Information is, thus, not necessarily free. It wants to be free. In the extreme this is seen by the "Streisand effect" where attempts to stop spreading information leads to more people spreading it, including the information bit that someone is trying to block this spreading. In the digital world this often happens by the direct copying of digital files containing said information, previously it often resulted in headlines in the news papers talking about it - all with the same information, all with a different wording (the letters on a news print are a form of data in itself, and as we all know the newspaper you have to buy but who won the elections you hear for free from your friends).

    So who-ever wants to use this adagio, please remember these core points here:

    • Information != data
    • It is free as in freedom, not necessarily free of charge,
    • And while certain information may be restricted, there is always the risk of leaks, and if it is leaked it will spread like wildfire.

    And please stop discussing pricing of data plans...

    Most countries have the power of the courts strictly limited to crimes committed within their own country. Other countries limit their jurisdiction to crimes committed within their borders, and crimes committed outside those borders by their own citizens.

And I recall even reports of US agents abducting foreign citizens in a foreign country, taking them to the US, and prosecuting them there.

    If it is legal to crack/circumvent DRM when you are "not committing a copyright violation", it seems that it is also OK to crack DRM on other works, as long as you do not redistribute it. A few comments up someone posted the actual Brazilian fair use rules, and those seem pretty fair, and explicitly allow a.o. for creating a copy for personal use.

    This would make it legal to say strip DRM from your legally bought iTunes songs, in order to make your personal copy.

    It would be legal to rip BluRay discs and removing the DRM in the process, again to make your own personal copy.

    Redistributing said material with or without DRM in place would be a copyright violation, and rightful so.

    It would presumably be legal to create tools to do this - it seems reasonably to expect that to distribute such tools would even be legal.

    Now the real fun can start: Brazilian programmer produces tool that removes DRM from material with US-owned copyrights. Fully legal in his native country. Would this person be liable to prosecution in the US? And indirectly by producing such a tool banning himself from visiting the US for the rest of his life?

    It's actually quite small. About 25x60x15 cm. It's instant heating, no reservoir, so indeed as long as you have water and electricity at full blast you have really hot water as much as the water pipe can handle (some 8-10 litres per minute or so), as much as you want. These things are actually quite common here in Hong Kong, said to be more power efficient than the reservoir type heaters.

    One problem is that when the water reaches our home the temperature is at 25-30 C already, so we need only very little hot water to reach 37-38 C, and at that low flows the heater tends to switch off. So in summer I usually just shower "cold". If having a shower during daytime in the high rise where I lived before I always had to wait for the cold water to become comfortably cool instead of literally burning hot (sun heating the water pipe which is on the outside wall).

    The higher IQ standard for Chinese has another reason, like the summary already indicates: the much higher pool of available candidates. The important part here is "available".

    Being too lazy to look up numbers, hereby some general statements without numbers to back them up. There are lots of university graduates in both countries - though the % of uni grads in the US is much higher than that in China. It may even be that there are more fresh grads every year in the US than in China, maybe China has caught up already, that I'm not sure of. I think the US is still ahead in that field. The US is certainly way ahead when it comes to research, it's not just because that there are some many Chinese (and other foreign) Ph.D. students working at US universities.

    Now to the available part. The US has a mature, knowledge based economy with lots of jobs for high educated people. Most uni grads will have no problem finding jobs that actually require their skills. So getting a uni grade to apply for a job in Shanghai isn't easy - the pool of people willing to go work overseas isn't that big.

    China on the other hand is an emerging economy, based around manufacturing mainly. There are jobs for high educated people, but not many. Finding a job is a real problem for uni grads in China. There are regular job fairs for graduates even, something I had never heard of before back home in Europe. And still it's hard to find a job for a uni grad. There have been fights (literal, as in punching and kicking) between fresh grads fighting for a job as a toll booth worker. You know, sitting in a small booth at the highway collecting toll from passing motorists. That's how bad the situation is there. There are simply not enough jobs for higher educated people. So companies will go for the cream of the crop - simply because they can. Even the cream of the crop is plentiful enough to have a nice pool of candidates left. For every position that requires uni level education and skills there are ten people available.

    In developed economies, having a university degree is more or less a guarantee that you will land a good job. You may have to search for a while but within a year most have a job, and the rest doesn't have a job because they're doing something else such as continued study or travelling. China of course is trying to develop an economy like that, and is rapidly increasing the size of their universities (currently iirc some 20 million students at China's universities) as that's a prerequisite for a knowledge based economy. For the jobs to be created however it will take a bit longer, causing this kind of problems and allows companies to require such ridiculously high IQs. All in all I think the number of IQ>125 and IQ>140 will be roughly the same in both US and China, as proportion of the population. However it will be a while before China needs those people (as in: has jobs that require those people).
