    Re:Here's a clue, luser...

    Oh boy! You know a post is going to have some mind-bending insight when it starts with a clumsy personal attack!

    10G supports optical PHY.

    Yes, but so does every other competing standard. The only thing keeping Ethernet alive is the backward-compatibility of the RJ-45 connector. But the power consumption of the connector means it will never leave the data center. This means that Ethernet has lost all traces of "backward compatibility," which means it will lose tons of steam in the impending 10G optical battle.

    Once we jump to optical, for short links (~100m), the cable can suddenly carry any standard you want. So it's the jump to optical that's important, and that's what Intel is trying to offer here: cheap optical. Eventually, one of them has to win, and 10G Ethernet is (for the moment) not really making any attempts to win that race to the consumer.

    Today, 1000baseT is included on $500 laptops, and you can get a 5 port 1000baseT switch for $25. If you think similar things won't happen with 10G, you're wrong.

    No. with 10GBASE-T over COPPER it's not a question of COST, it's a question of POWER.

    10GBASE-T uses too much power, all because it takes more power to get a higher bandwidth signal over the same 100m of copper as Gigabit. Current estimates are about 6W for a controller, which is way too high for integration into chipsets. And you can only reduce the power required for the DSP logic on the controller - the amount of power it has to deliver to the line to meet 10GBASE-T signaling standards is a fixed quantity. Since the power numbers I quoted are for second-generation devices, you can bet your ass that the DSP power quotient has been reduced to almost nothing, so that 6w is almost entirely signaling power.

    Hell, even low-power Gigabit controllers use over a watt - this is why a lot of low-power devices still ship with just Fast Ethernet. The industry is moving toward EEE (Energy Efficient Ethernet) to combat this, but it's really nothing more than an idle mode - peak power is unchanged.

    Optical offers very low power consumption at 10G (less than 1w), but will require the adoption of a new connector standard regardless of what standard the market goes with. Intel sees the opportunity here: if people will have to buy a new infrastructure to use low-power 10G, they will buy whatever is cheapest, not whatever is used in the server room.

    Doubtful, no one other then AMD is able to succesfully compete in the graphics market, also AMD does not have any GPU's or ultra mobile devices, and that market is simply enormous

    So enormous that AMD was forced to sell the long-running ATI Imageon line just 8 months ago. If what you're claiming is true, they should have been making money hand-over-fist...but they weren't. All this despite that fact that the only other 3D player in the market is PowerVR!

    and nvidia is hoping with their next gen mobile chip to get into everything from phones to portable video players, that is a growth market.

    Portable video players are a saturated market. You know when Apple caves-in and adds video RECORDING to their dying iPod line, that video playback is already thoroughly entrenched. And don't give me the bullshit that HD video playback will somehow kick-off a new "revolution," when the devices are too small to gain any benefit whatsoever from HD video (screen is too small).

    The Zune HD is the only HD-capable player on the market, and the screen can't take advantage of this. You need a clunky dock and a real monitor to see the difference, and the number of people who will buy it for that purpose is small indeed.

    Back to the subject, every single competing smartphone-level chipset can already do video pretty well, so why are people going to spend money on Tegra (especially when you don't even get a Coretex A8)? For the 3D graphics, of course! And that means you're entering yet-another saturated market: portable 3D gaming.

    Yeah, I have to agree: I don't see Nvidia dying anytime soon, but I have to say that (barring some impressive new market), their days of growth are over.

    Intel has locked Nvidia completely out of the Intel chipset business, destroying one of Nvidia's major market segments (who buys Nvidia to run AMD processors anyway?)

    Yes, it's absolutely true I downgraded the amount of light in the process getting down to 120w. The light I have now is the equivalent of 3x60w normal bulbs (2400 lumen), whereas the previous owners had installed a 75, 75 and 100w bulb (4000 lumen) to make it brighter (easier to sell).

    After thinking about it, I realized that this was way more light than I needed - for incandescent bulbs.

    But here is where the science ends and my personal tastes begin: I had a full-sized fluorescent ceiling light in the kitchen at my old place (2 circular elements, 2x22w, 2300 lumen), and I always found the light to be cold. Despite that fairly high lumen rating, the room never felt all that bright, especially compared to an incandescent of a similar lumen. So when I did my comparisons, I assumed I would have to keep the same lumen if I went with florescent, hence my 60w estimate.

    I'm actually very happy with my current 3x40w Halogena "downgrade" (2400 lumen), despite the fact that this kitchen is larger than my last one. The amount of light really is enough, and the *quality* of the light makes a difference in just how much I need.

  9. Law of Diminishing Returns on Panasonic's New LED Bulbs Shine For 19 Years · · Score: 1

    I just moved into my new house, and since it's just me, I only leave two lights on most of the time (kitchen and hallway). One is a 250w incandescent set (3 bulbs, kitchen), and the other is 75w incandescent.

    I got my first electric bill, and found that the kitchen light was costing me $25/month. So I looked at my alternatives:

    Can switch to CFL for around 60w (save $19 /month with no change in habits).

    Can switch to Philips Halogena for around 120w (save $13/month with no change in habits).

    Can just be more aggressive about turning-off the kitchen light when I'm not in it.

    In the end, I decided to go with the Halogena setup plus a more aggressive stance on turning-off that light. I really like the light quality of the incandescent - it is especially important because the colors of the room are all warm earth tones, and would look sick and dead under the blue/white light of CFLs. Plus, I really don't like the idea of having bulbs filled with mercury in a room with a ceramic floor (it magically attracts glass objects, and they create explosive splinters) and in a low-hanging light fixture that people constantly hit with objects. I've already had to clean-up one broken glass container in my first month living here, and I don't want to have to keep a Hazmat kit just in case the inevitable happens.

    I was just surprised at how MUCH I could save by moving to a more efficient halogen, and how little on top of that you save going to CFL. Ahh, good-old Law of Diminishing Returns.

    Not true, this is an opportunistic bacteria that lives in stagnant water. It can find the stagnant water without being introduced through the water supply (through air or other contamination). Since a person with dirty hair is only inches away from the shower, it's not hard to see how it might get contaminated. In the same way it can get inside your lungs (aerosol), it can also get inside your shower head.

    The shower head is sitting idle most of the day, and since the chlorine in the water quickly dissipates in air, the water left remaining when you turn the shower off is quite welcoming to the bug. Yeah, it gets hit with chlorinated water at least once a day (you do shower regularly, right?), but the amount of chlorine in the water at-delivery is way too little to kill entrenched bacteria (that happens at the treatment plant, with much higher concentrations of chlorine, and UV treatments). You might kill a small amount, but the strong survive.

    See here for proof. The average number of processors sold in an Itanium server is around 4 (In 2007, ~200,000 processors went into 55,000 servers).

    Itanium has almost no showing in the single-image supercomputer and large cluster market. IBM has the RISC large performance cluster market cornered, and the rest goes to x86-64. There's barely a few crumbs left for Itanium, and the market share is quickly shrinking.

But since other fields are already reducing production over time, it will only soften the bleeding of older fields, not allow for a real increase in US domestic oil production.
