    Yea, Emacs is way to simple and limited to be effective. There's only a little more than 10,000 commands, but fortunately it supports macros and some limited scripting so it's possible to use it for some limited editing... Seriously, it's has a learning curve steeper than most programming languages. Personally I feel you shouldn't spend more time learning to use the editor than programming...

    The mere thought that Vampires might exist in those books throws science out the window. If we are to accept that vampires are real, then we have to accept that there is some "magic" at work and that we doesn't know how it works. Why blood? Why the blood of sentients, or human blood, or in some versions only the blood of virgin humans? To be able to read a story involving vampires we have to ignore all of these things, so what makes it so hard to accept the idea that you could give blood orally to a woman pregnant with a vampire baby when we doesn't even know why they need blood in the first place? Yes it's stupid, but it's only marginally more stupid than the entire genre as a whole. Now I can't really comment on the Twilight books as I've never read them and all I know about them comes from internet haters, most of who I suspect never read them either.

    First time meeting an immortal... I think walking through the table wasn't helping. Apart from the "space whale" this is the first supernatural being he has met, and having her walk though the table probably had him thinking about ghosts and spirits, maybe even vampires rather than immortals at first.

    Hadn't heard about the diamond coated wire. That article talks about using it in processors so I think it will conduct, but it's not for bonding chips but rather for connecting individual components on the chip. Compared to the internal signals on a chip the external signals are quite "crude", using relatively high voltages and currents.

    You can make thinner wires out of gold, but as gold isn't as good a conductor they have to be thicker than the equivalent copper wire. And thicker means more expensive, so unless corrosion resistance is very important, or it needs to withstand a lot of vibrations copper is often the preferred material. For common components vibration is not a problem, thermal expansion can be a problem, but in low power electronics it's not a big problem and copper is usually good enough.

    I wasn't talking about the visible parts of the chips. It used to be that all integrated circuits used gold wire to connect the chip to the external connections on the packaging. Here is a picture showing what I mean. I have however looked around a bit and apparently copper is often used now, and for low power and cheap circuits they can even use aluminium. Old processors using a Pin Grid Array package had pins made of gold. These were soft and prone to bend when inserted into the sockets, but didn't usually break unless you wiggled them around. Later versions moved to Ball Grid Array, and on these the contact surfaces are gold plated. The "pins" in the socket are made of a bronze alloy which is also gold plated. Gold is used because it doesn't corrode, it's soft and malleable and a decent conductor.

    I looked around a bit and it turns out that you are correct. Gold was the material of choice a few years back, but for a lot of circuits they are not using copper and for the cheapest possible even aluminium. Gold remains the choice for high power and high reliability solutions. Copper is actually a slightly better conductor and the bond wires can be made even thinner than with gold, but it's also more likely to break due to metal fatigue. Gold has a weakness in that if bonded to an aluminium surface it may develop something called "purple plague". This is a intermetallic compound of aluminium and gold that's a bad conductor and mechanically weak. This occurs when the joint is heated to more than 650°C. At lower temperatures in the range of 400-450°C other compounds can form.

    I think you misunderstand what they are talking about here. The IHS that they write about is the Integrated Heat Spreader, and Intel has used solder or a TIM back and forth ever since they started using these. So Intel not soldering the IHS on a series is nothing remarkable. The core however is, and has always been, soldered. Further more even the cheapest chip will be bonded using gold wires. There is simply no material able to replace gold for this.
  10. It's a well known fact that cats tend to assume the shape of their container. Some go as far as claiming that cats are a liquid, and the evidence can look quite convincing. Given these properties all you need is a container shaped as a standing cat and a feline willing to sleep in it. Unfortunately this seems to be a rare combination so the best approximation I've found is this.

    Thank you! Well, that's hardly a cosmetic change? Thought (yea, rare enough for me): The size change spells (and the TF-gun) must have a secondary effect in that people who are transformed doesn't seem to have any problem adapting to a different center of gravity or a change in the length in the limbs... Not really of interest for this discussion, but the novelty of having an idea made me pause to type this up.

    Rhoda is the size queen... (That sounds so wrong all of a sudden...) Shorter, longer, fatter, skinnier, resize the clothes or not, resize part of someone or something, and she's able to change the size more than any of the other cast members who can do this. So resizing is her primary talent or theme if you like. Other things such as changing hair color isn't her primary forte (someone please remind me where we learned she could do that, my memory fails me). I'm not certain in what way her cosmetic capabilities are second to the beams Ellen use. Perhaps the effect wears off quicker, perhaps she can only change hair color to something that occurs naturally while Ellen can make it glow-in-the-dark plaid. Who knows...

    This... Or they could be a bit underhanded and have one of their researchers work as his assistant to keep track of his research. This last is a bit risky though. As it is he is the Golden Goose, and if they are smart they will try to keep from rocking the boat and risk Tedd telling them to go pound sand.
