    Buying a flight (for example) from Paris to Tokyo is cheaper if changing planes in London, but it is also cheaper to fly from London to Tokyo through Paris, using exactly the same intercontinental flights.

    The rationale is that by lowering the price of flights with two parts, you are poaching the clients of the local flag carrier, but with a substandard product due to the increased flight time and the inherent inconvenience. Conversely, incumbent flag carriers do not encounter a lot of concurrence on the direct routes, which means that the prices are geared towards what the customers can pay rather than what the flights cost.

    For a reference point, the Bluecars used in a car-sharing service in Paris are for sale at about €12k, after a €7k subvention, but you need to pay an additional €80 a month for battery rental + battery exchange at 400,000 km. And it's a very spartan car, with 4 places but no trunk, clearly designed for city-only use.

    You should look at LWN. It's a news site maintained by Jonathan Corbet, who co-authored the popular 'Linux Device Drivers' books for 2.4 and 2.6 kernels, and maintains a weekly newsletter about what currently happens in the Linux community. It also maintains archives, which gives it an index covering the widest range of topics in the Linux kernel.

    You can read the 2.6 driver book on LWN as a starter, as there is no radical departure between Linux 3.x and the 2.6.x series. You can even grab an older copy/branch of the kernel like 2.6.32 and run it in a VM, as then there will be no difference between the source you use and what the existing books contain.

    As Skype is a network, and does not offer interoperability, it benefits from a network effect: its usefulness compared to its concurrents is the square of the number of ts consumers. This usually leads to a natural monopoly, and Microsoft must have recognized it.

    You're hopelessly wrong about the origin of Copts. The term itself comes from the 'gpt' consonants in Egypt.

    They were living in Egypt before Muslims ever existed, and they still live there because even int the 9th century, Muslim invaders understood that expelling the vast majority of its population is not the right way to do a conquest. They resisted islamic assimilation for 14 centuries, including periods when they were violently reprimed for this. Except for a short period during the Crusades, there has been no direct conflict between Western Christians and Copts, and there was never any significant movement of population from Europe to Egypt.

    Who thinks the EU doesn't spy on the US?

    Just for measure, as you may not understand the EU institutions.The European Council is composed of the governments of the states of the EU. It usually works by organizing reunions of ministers for each political domain, as well as reunions of the heads of government, and that's currently the place where important decisions are taken. Given that there are 27 members, it is a piece of cake for the US to know what is said in there, and some countries' governments will gladly tell the US if they ask. Except that they may distort the message to fit their interests. Thus, it is interesting for US spys to get the information directly.
    But on the political level, this spying is tantamount to bugging the White House's main conference room.

    We may make a difference between government and distinct individuals, but in the end, the only thing that can stop a government is its own people. As long as the citizens of the States of the Union continue to tolerate unlimited corruption in name of "campaign contributions", broken election methods for representatives, and as long as this corruption leads them to elect a leadership with the same behaviour, the rest of the world can only conclude that the people of the USA wants it.

    It's not really possible with USB out of the box. In this case the charger is the host, and is at the origin of all transactions. You need to add another layer over the existing protocols to require the host to give some credentials, before changing the device profile and exporting the interesting interfaces. This means a new WHQL certification / kernel update for your drivers, and ensures that it will not happen immediately.

Whether it's done by software rendering in the old J2ME games, or now by hardware-acceleration on iOS and Android, the common point for all new platforms has been OpenGL ES. It will continue to see evolution and improvement, and nothing will prevent these improvements from going back to the PC. Notably because there is no hard distinction left between a Linux PC and an Android device nowadays.

    I recognize I was wrong in linking the low bandwidth problem with the number of pins, because I referred to the HDMI/DP standards, that used multiple lanes to increase the bandwidth, instead of USB3 or MHL, discussed elsewhere in this thread, that prove that the feature is possible.I spend long enough with hardware controllers to know that there is a wide set of protocols to interconnect two systems, and in my opinion the serial/parallel classification is not interesting.

    In the end, others manufacturers achieve to do what Apple doesn't: a small, standard connector with good A/V support. It is Apple's choice when upgrading its connector to degrade a working feature, adding latency and artifacts, while producing a proprietary connector. You see it as a good thing because cables are useless; I don't.

  19. Where do you see "serial" in "Lightning"? on Apple's Lightning-to-HDMI Dongle Secretly Packed With ARM, Airplay · · Score: 1

    The serial/parallel distinction is completely useless in here. But you're right on the pin count.

    There are 9 pins in a full size USB3 connector, and 8 pins in a Lightning connector. But when the lightning connector has two data pairs, USB3 has a bidirectional pair for legacy, and two single-direction pairs for high-speed traffic. HDMI, and Displayport respectively have 3 pairs (+ 1 differential clock) and 4 pairs.

    The real question is the nature of the signal on those pairs. USB2 is 480Mb/s with a lot of protocol overhead, HDMI has 3.40 Gb/s with only error correction, and USB3 is 5 Gb/s, but still has (parts of) its inefficient protocol. Depending from what Apple is doing, it could route only the high-speed signaling of USB3 on the Lightning connector's two pairs, and provide the same performance as a standard USB3 cable.

    However, since Apple keeps all information about Lightning under wraps, only insiders can tell. And until now, all we've seen is quite underwhelming, with USB2 data cables, and now this adapter.

  20. Re:Car analogy on Apple's Lightning-to-HDMI Dongle Secretly Packed With ARM, Airplay · · Score: 4, Insightful

    Don't get confused. The high-tech Intel interconnect once known as LightPeak is called Thunderbolt. Here, we are talking the proprietary, low-tech, USB-like symmetrical connector Apple uses on their recent iOS devices, whose name is on purpose confusing everyone with its better counterpart.

    And from what we see here, it's markedly worse than the alternatives Apple shunned, but that were based on standards (MHL, USB3), because those would have prevented Apple from imposing drastic licensing conditions on accessory manufacturers.

  21. Disappointing for a new connector on Apple's Lightning-to-HDMI Dongle Secretly Packed With ARM, Airplay · · Score: 3, Informative

    Was the change really worth it?

    With its limited pin count, it's not a surprise that the Lightning connector does not have the bandwidth to transfer uncompressed video. But it's disappointing for it to be so bad at compression, with the MPEG artifacts shown in the article, plus latency issues with encoding/decoding. On that point, the old connector was better, and micro-USB3 would have had enough bandwidth to avoid the issue completely.
