Anything beyond this month doesn't really exist. Besides, a lot of people already have big cell phone bills, so it's not really fair to account the cost of service to the iPhone.
in order to make their products seem faster than the next guy, someone jumped the gun and released a product based on a draft standard. Of course, since that industry is made up of sheep, the others followed in short order
Companies are hardly sheep for trying to seize a first-mover advantage.
Also, the Wi-Fi alliance is testing and certifying interoperability of 802.11n Draft 2.0 equipment, so in some sense it is a standard, just not an IEEE one.
Why should google redirect you to joe random's copy of the same AP story when they can display it themselves?
It costs Google nothing to link to another site, while it costs them to syndicate wire stories. OTOH, if Google displays the story they can keep the ad revenue.
Clock modulation makes the processor slower but less efficient, so I don't recommend it. I think the results from these benchmarks would actually be worse if clock modulation was used. I wish Linux would go ahead and remove the p4_clockmod driver so that people like you will stop making their systems less efficient.
For a Xeon you want to use EIST instead of clock modulation; the proper driver is speedstep_centrino or cpufreq_acpi (depending on kernel version) and SLES 10 loads this driver automatically, so there's no need to tweak settings.
US telcos chose ATM-based BPON and GPON equipment that is compatible with their existing DSL mindset and management infrastructure, and those standards were designed to be asymmetric. Japanese ISPs chose EPON because it is cheaper and faster and they don't care about backwards compatibility.
I don't fully agree with the parent post, but it's not a troll. Some of these are legitimate issues.
there's no discussion as to the optimizations made to the software being run on each of the boxes. Is the code compiled for each architecture individually taking into account support for 3DNow / SSE instructions, cache sizes, etc? Obviously more efficient or less efficient code execution would have a MAJOR impact on these studies, enough so that companies usually spend a large amount of time playing with compiler options to get the best performance on a given architecture.
In the real world, people use the binaries that are provided by the distro, which is also what was done in this test. Apache and MySQL are not particularly amenable to compiler optimization anyway.
The article does not mention it, but SLES 10 enables cpufreq and the ondemand governor by default.
AMD power utilisation with reduced frequency in idle is higher than that of a Xeon system which consumes nearly nothing when you slam it down to 250MHz.
Uh, the lowest frequency of the Xeon 5160 is 2GHz.
The point of the study is the relative power efficiency of the two processors, not absolute power efficiency. If you need the performance of an Opteron or Xeon, why wouldn't you choose the more efficient one (all else being equal)?
So the only possible way to get decent quality and decent speeds at a decent cost is to pay uploaders for connections. That way, they will actively choose to allocate their upstream bandwidth to the company, instead of to a competitor.
I am having flashbacks to the companies that promised to pay for idle CPU time on PCs; are any of them still around? Is your system actually cheaper than a conventional CDN? Will you accept liability if my ISP cuts me off because I used their service "too much"?
The Eden/C7 is 30 sq. mm., so 64 of them would be over 1,000 sq. mm., which would cost a fortune to manufacture. In comparison, high-end server processor chips are generally in the 300-400 sq. mm. range.
Just because a cable box is required to support OCAP doesn't mean that it has to only support OCAP, right? So TiVo should be able to build a box that has the native TiVo GUI and also allows users to view OCAPlets through a menu option. Maybe we should call it OCRAP.
Because of all their weird restrictions, GPUs are going to be much harder to program than this Tilera chip. Let me know when somebody is running Snort on a GPU.

What good is Skype if you have no microphone?

I think it's a cultural difference. The Japanese embrace change; US telcos fear it.

As I said earler, the ondemand governor was already used in these tests, because SLES 10 enables it by default.

Xeon 51xx (Woodcrest) is essentially the same as Core 2 Duo (Conroe); it is very power-efficient.
OTOH, WiMax base stations are 10x the price of WiFi ones and customers would need to buy expensive CPEs.
So the only possible way to get decent quality and decent speeds at a decent cost is to pay uploaders for connections. That way, they will actively choose to allocate their upstream bandwidth to the company, instead of to a competitor.

Open Source Intel AMT Drivers and Tools. (the part that runs on the PC), Intel Active Management Technology Reference Design Kit (the part that runs on a server and remotely takes over the PC).
Or does this mean it uses less power per cycle, thus allowing them to ramp up the clock until it's back up to 130 watts?
Yes, they are increasing the clock to maintain the same TDP.
But all open source licenses allow unlimited copying, so this is not a problem.

You're confusing mega and kilo in several places.
OTOH, the cabling will be more expensive and complex. AFAIK there are no standard connectors for -48V DC.

What's the instruction set of your router? Your TV? Why does it matter?
The UltraSPARC T2 (Niaraga 2) has 8 cores and 64 threads, so Tilera has more cores, more functional units, and an equal number of threads.
