  1. Re:just replace HDMI with Ether on HDMI 2.1 Is Here With 10K and Dynamic HDR Support (engadget.com) · · Score: 1

    HDMI has vastly more capacity in one direction. Modern ethernet is full duplex. If you replace HDMI 2.1 with ethernet, you first have to use twice the lanes, and half of them would then sit mostly unused.

    You could use plain 100Gbps ethernet over copper, but even the cheapest transceiver options would be close to the cost of a cheap TV.

  3. Missing the most important change on HDMI 2.1 Is Here With 10K and Dynamic HDR Support (engadget.com) · · Score: 1

    HDMI 2.1 gives you a usable Audio Return Channel! ARC gains enough bandwidth to actually make a surround sound setup worthwhile, it gains reliability since it isn't dependent on 1kHz CEC signalling with dubious vendor support, it gains more reliability because the wires it runs over are guaranteed to be properly shielded (little known fact: If you want to use ARC on HDMI 2.0 and below, buy a HDMI-ethernet-cable), it gains usefulness because it contains a lip-sync signal so you don't have to fiddle with audio delay settings to get video and audio to line up.

    It will transform surround "receivers" completely. No longer will they need 7 HDMI inputs and go obsolete the moment the next HDMI standard comes out. No longer will they need complex remotes to try to get the right audio and video to the right outputs. No longer will they struggle with getting HDCP through from box to TV. You will simply plug the "receiver" into the TV with one HDMI cable, and the TV will do all that -- and the "receiver" will go back to its proper function and be a pure amplifier.

    Overlapping windows don't work in any of the popular window managers anyway. Not in Windows, not in Mac OS, not in Gnome. You cannot have the window at the back be active so you can type in it, so you cannot use the contents of one window to do something in a different window.

    The only solution is to avoid overlapping and tile instead, but again, Windows, Mac OS, and Gnome all fail spectacularly at that too, although they are beginning to at least try.

    It isn't a problem that different architectures have different ABIs. The problem was that different compilers, and even different versions of the same compiler, had different ABIs on the same architecture. Sometimes different enough to make linking fail, sometimes just different enough to make things break at runtime.

    The C++ compiler is vastly better than it was 20 years ago, for one thing.

    Also, you missed the ABI stability part. 20 years ago it would have been hard to support loadable modules compiled separately from the main kernel if the kernel was C++. Today, that would be much less of a problem.

    Desert air is generally quite wet, in an absolute sense. In a relative sense it's low humidity, because warm air holds so much water. But cool it down to 5C and you'll see quite a lot of water precipitate out of it.

    I did a quick Googling, and Phoenix apparently has quite high relative humidity in summer, whereas it is lower in spring and autumn. This is handy, as that means the water extraction has lots of humidity available right when solar panels are at peak output.

  16. Re:are AMD and intel cpu interchangable on Arch-rivals Intel and AMD Team Up on PC Chips To Battle Nvidia (pcworld.com) · · Score: 1

    It definitely is worth remembering. I have never heard that side of the story. Do you have any references for this?

    I have read stuff like this one:

    "The CPU dispatch, coupled with optimizations, is designed to optimize performance across Intel and AMD processors to give the best results. This is clearly our goal and with one exception we believe we are there now. The one exception is that our 9.x compilers do not support SSE3 on AMD processors because of the timing of the release of AMD processors vs. our compiler (our compiler was developed before AMD supported SSE3). The future 10.x compilers, which enter beta this quarter and release around the middle of the year, will address this now that we've had time to tune and adjust to the new AMD processors."

    which perpetually keeps performance for new AMD CPUs down until a new release of icc happens to come out, and everyone (right) recompiles their code. Since most benchmarking is done right when a CPU is released, and because a CPU is most expensive when it's first released, this puts AMD at a disadvantage.

    It will also mean that you can hit cases where a newer AMD CPU runs code slower than the old one, simply because the icc compiler had the old one on the whitelist but not the new one at the time the code was compiled.

    And many libraries I had to use were pre-compiled to generic specs rather than optimized.

    Or they were compiled with icc, which adds check for whether the emitted code is running on an Intel chip, and jumps to generic unoptimized code if not. If it IS an Intel chip, the code does the usual flag checks to see which modern instructions are available and runs the appropriate code, but on non-Intel it doesn't get as far as checking flags.

    Because the vast majority of files on most PCs are completely standard system or program files that no one really cares about getting encrypted. Fixing them is just a reinstall away, and the traditional ACL's are likely to prevent the wrong kind of access anyway.

    There is no such ability in Linux or *nix, since ACLs are solely based on uid and not the name of the executable with your uid.

    Yes there is. There are even two in Linux, SELinux and AppArmor.

    However, there is no easy-to-use GUI to administer it per-user, which means that you rely on the way-too-permissive default policy for most programs. This could have been done years ago technically, since SELinux and AppArmor are both quite old, but no one had the right idea apparently.
