    Wrong. Why don't you do some basic fact-checking yourself before wrongly accusing others?

  2. That was not my impression. There's a bulk, "mechanical" process where the temperature stays constant because water is boiled into steam which leaves the system. But there's also an underlying, physiochemical phase transition where you could (theoretically) add energy just short of the enthalpy of vaporization without generating any additional steam (remember, the saturated gas phase issue). You can't actually do that due to statistical thermodynamics, but the enthalpy of vaporization is a form of physical bond breaking, not merely energy being lost due to the generation of steam.

  3. The reason water absorbs heat at 100C and doesn't increase in temperature is because the kinetic energy of some of the water molecules become high enough that they escape the pot in the form of steam.

    That is not what he was referring to. There's an enthalpy of vaporization that requires that you transfer energy to the system (heat) in order to make the leap from liquid to gas at the boiling point of the liquid. That phase transition occurs at constant temperature so long as you're maintaining constant pressure, gas phase saturation, blah blah blah (the typical simplifying assumptions made in physical chemistry texts).

    Yet I have seen very little research into this possibility that could pose a valid explanation for Earth's present climate changes.

    There's been very little research into this possibility because it violates the laws of physics. You could not consistently orbit "slightly lower in altitude of [Earth's] planar orbit around the sun" without the near constant intervention of really, really large rockets.

    Pick an orbital plane that you want to label as the "normal" one. Now shift the planet "below" the orbital plane due to, say, the combined gravitational pull of most of the other planets (September 2040 superalignment; y'all's days are numbered!). The problem is that the planet will still orbit the barycenter of the solar system, which also moves around slightly, but not much. The barycenter will "pull" the planet up. Thus means that, just like when you spin a tetherball in a flat plane and then push or hit the ball down, if the Earth were to descend "below" the normal plane, it would for half an orbit but pop up "above" the orbital plane for the other half. Blah blah blah, Earth gravity and air resistance to rotation of the ball make this a poor model, but at least it's within the realm of ordinary experience.

    Guess what already causes the northern hemisphere to be warmer and the southern hemisphere to experience the opposite? The axial tilt of the Earth's rotation relative to its orbit.

And it reduces the cost of the service for the hotel by allowing bandwidth limiting on the controlled "free" access.

    The concept went right over your head, didn't it?

    If you set up your own WiFi hotspot, say using your cellular phone, you are not putting traffic on the facility network, you are not causing the facility to incur costs for bandwidth, and you are not in any sense the facility's local client. You are a client of your cellular provider's network, using a your own WiFi connection between your own cell phone and your other devices (over public airwaves; without connecting to the facility's WiFi network). That connection is presumably entirely private to your own devices (assuming that you're password protected your hotspot; my own device will not provide a WiFi hotspot without one).

    Putting a firewall between a customer and the customer's cellular provider is not the facility's job. Policing the internet (as opposed to the facility LAN) is not the facility's job. And appropriating public airwaves (in this case WiFi frequencies) for the exclusive use of the facility is quite simply illegal.

    Security reasons have very little to do actively interfering with WiFi hotspots. There is only one potentially valid concern - SSID spoofing. If you want to take on the FCC concerning that issue - go for it.

    It's copyright infringement whether the copy was activated or not - the copyright act prohibits unauthorized reproduction, not unauthorized activation. The copyright is also registered. That means that they are entitled to statutory damages whether they could have acted to further limit their losses or not.

    But allowing thousands of fraudulent activations is a joke. More than a few a year should trigger alarm bells at Redmond.

    They have three years to file a claim.

    MS can't prove either of these. Even if they know the authorized licensee, they don't know who is using the keys thousands of times. They can't know who it isn't without knowing who it is. If they knew who it is, they wouldn't need to subpoena for info. The same thing goes for the region.

    They don't have to prove either of those at this time -- they simply have to show that what they are requesting is relevant to those facts. The identify of the subscriber is certainly relevant to determing whether that person is an authorized licensee and is licensed to use those keys within that region.

    It's also not the court's job to enforce the minutia of the license terms such as region, number of activations, transference, etc., especially when MS is so lackadaisical as to allow the keys to be stolen and for unauthorized activations to go on for so long.

    It's precisely the court's job to enforce the minutia of the license terms, because the license terms are a condition of the license (e.g., "we grant you the right to install and run that one copy on one computer (the licensed computer), for use by one person at a time, but only if you comply with all the terms of this agreement." Without the license it's copyright infringement. The rules don't change simply because it's Microsoft enforcing a windows license and not an open source advocate enforcing the GPL.

    Simply, no.

    You are right about the physical PCIe slot connectors.

    You could be right about the physical PCIe slot wiring, but in many boards with two x16 slots (assuming that there are only two, with the chipset-wired slots not being physically x16) both are electrically wired to be x16. You do not have to put a card in a specific one of the two slots to have an operational x16 connection.

    You are wrong about the functional connections. I'll assume an Intel-compantible motherboard since that is what I'm familiar with. AMD-compatible motherboards could be different - I simply do not know.

    Intel CPUs provide 16 PCIe lanes for connection to the x16 slot(s). If you have one card inserted, that slot will be allocated all 16 lanes. If you have two cards inserted in a board providing two slots, each slot will be allocated 8 lanes. In Z170 boards there could be three CPU-connected slots, and with three cards inserted in such a board, the slots would be allocated x8/x4/x4. See here.

    Everything else runs off chipset-provided PCIe lanes, which are connected to the CPU by a PCIe x4-like . Thus, for example, in my Ivy Bridge system (Z68), there is a third PCIe x16 physical slot that is PCIe x4 electrically wired and functionally PCIe x1-connected unless I set a BIOS option that disables certain other peripherals (USB3 and eSATA add-ons).

    If you connect your GPU and this SSD at the same time, you will be either x8/x8 (if using CPU-connected slots) or x16/x4 (if using one CPU-connected slot and one chipset-connected slot). That x4 would also be shared with every other I/O connection in the system due to the DMI "x4" like bandwidth limitation.

    PCIe PLXs switches add lanes to slots, but do not add further connections to the CPU or chipset. At the end of the day you're sharing either the 16 CPU-provided lanes or the 4 chipset provided lanes in Intel's consumer-oriented boards. You have to go to the LGA2011 socket and workstation chipsets to gain more available bandwidth to the CPU.
