I don't know what your temps are, but mine were (all C, all idle) 61 CPU, 36-39 on the drives (5) and the 8800 at 63. I swapped out an old slow NZXT 120mm fan for a new 65 CFM Thermaltake 120mm and replaced the stock cooler with an OCZ I had bought and lapped but never installed. Now, the temps are 38 CPU 32-36 on the drives and the 880 idles around 58 (upped the fan to 80%). It was likely a combination of dust and low RPM/CFM fans. I have another of the Thermaltakes I'm going to put in the front soon. Thanks for the reply.

Three are Maxline 250GB server drives, one is a WD2500YD server drive (in the enclosure). It's likely the older Maxlines are generating the heat. My computer drives are Western Digital WD5000YS 500GB (x4) and a Seagate ST3500630A system drive 500GB. But, they're in with a hot 8800 GTS Nvidia card and my CPU in an Antec 300 with 5 120mm fans. Likely not enough air flow :(

Agreed! Powering and cooling the five internal drives in my tower (1x system- 4x raid) was/is a struggle, let alone twelve TB drives in a conventional tower setup. I would rather opt for a couple external mini-towers with controllers. Even then the cooling on these units is typically not up to par. I'm currently reviewing a 4 bay NAS cube that has nice features, but with a full load of drives it struggles-- temps went from 75 with one drive to 120+ with all four. Just because it can be done doesn't mean it should be.

ISS Launches First Permanent Node of "Interplanetary Internet" 121

Posted by timothy from the wake-me-up-when-the-terminator-gets-here dept.
schliz writes "Researchers developing the 'Interplanetary Internet' have launched its first permanent node in space via a payload aboard the International Space Station. The network is based on a new communications protocol called Delay/Disruption Tolerant Networking (DTN). It will be tested heavily this month, and could give astronauts direct Internet access within a year. The Interplanetary Internet is the brainchild of Vint Cerf ('father of the Internet'), among others. Last year, NASA tested the technology on the Deep Impact spacecraft." Update: 07/13 20:01 GMT by KD : If by "permanent" we mean seven years.

Submission + - Hard Drive costs dropping (tomshardware.com)

Submitted by Drawsalot
Drawsalot writes: After seeing a post online that hard drive costs were "really dropping", it seemed to me that perhaps the lowest price is not what users should be after. Everyone bemoans the loss of data, so shouldn't reliability be the deciding factor? Personally, I'd rather pay a bit more and have less chance of losing my data. Are there any hard drive insiders in the readership that can tell us the difference between the various types of hard drives being produced? Are the 'enterprise' drives really built with different parts or methods so that they last? Which drives should we consider if reliability is key?

I've built high-performance PC's because I need the power for DTP and video rendering-- just so happens they also have the muscle for gaming when I add in a mid-level graphics card. Powerful processors and storage, storage, storage. My builds let me play all but the most intensive games at reasonable frame rates.

Even though this is a stupid topic-- anybody can build a "gaming" PC. Question is for corporations, 'Can we build a gaming PC profitably?' In the case of HP the answer is likely no. They have enough trouble remaining profitable as it is-- as do other OEM PC builders. People want $299 PC's, and you can't put decent hardware in a box and sell it for that amount. The people willing to spend $1,000+ for a PC are not as common. People who want a gaming machine are either going to build it themselves or buy an off-the-shelf system and hop it up.

I bought a Thermaltake 700 with modular outputs- I have since moved it and the other components to a larger Antec case (now a 300). I connected it and left it alone and have had no problems. Perhaps it's the brand. I liked being able to eliminate some of the wiring that was not needed in order to improve cooling.

Submission + - How to improve a water distribution system?

Submitted by ildefonso
ildefonso writes: Hi!

I live in an small community which have a "rural" aqueduct, and I would like to improve it. Currently, it is just a pipe from the river to a tank, and a 2" pipe down the mountain and 1/2" pipes to each house. In summer time, when water starts to fail, they close the main valve in order to allow the tank to fill, and then open again for some time. But due to the lack of some kind of control, when the main valve is open, the only houses that receive water for a long time are the ones that are at the lowest height, the ones that are higher receive water for a short period of time, and sometimes doesn't receive anything at all.

Anyway, here are my ideas:

My "normal" idea: I think that if I add some valves at different heights and adjust them correctly, I can get an improvement in the fairness of water distribution.

Now, my geek idea (sorry, it can't be helped, I'm a geek): I have also thought about adding volumetric flow meters to each house, and have an automatic cut-off valve, centrally controlled, to cut the water when the house have consumed it's daily quota.

The system could be implemented using a ZigBee mesh (geek), or an RS-485 network (not so geek) and some hardware that is not so expensive (around US$20-US$30 electronics per device), but if you add each of the about 500 houses, then you have big bucks, I can go with the electronic design and building myself, but I don't have enough knowledge as to choose valves, flow meters, and that kind of stuff.

My geek solution can lead to a "never-ending" supply of water to the houses that save water, but can probe to be expensive, even by building the system myself.

I would appreciate any suggestion on how to improve a water distribution system. (yes, even the fun ones). Also, any opinion on my normal and geek idea, is also welcome.

Thanks in advance,

Submission + - Einstein's twin paradox resolved

"The fact that time slows down on moving objects has been documented and verified over the years through repeated experimentation. But, in the previous scenario, the paradox is that the earthbound twin is the one who would be considered to be in motion — in relation to the sibling — and therefore should be the one aging more slowly. Einstein and other scientists have attempted to resolve this problem before, but none of the formulas they presented proved satisfactory. Kak's findings were published online in the International Journal of Theoretical Science, and will appear in the upcoming print version of the publication."
"The implications of this resolution will be widespread, generally enhancing the scientific community's comprehension of relativity. It may eventually even have some impact on quantum communications and computers, potentially making it possible to design more efficient and reliable communication systems for space applications."

Submission + - The *REAL* facts of Linux vs Windows ?

Submitted by yorugua
yorugua writes: From the report: "Considering the publicity that has surrounded — and, despite super new security-focused Service Packs, continues to surround — Windows security issues, Microsoft's determination to demonstrate that Linux is less secure than Windows shows a certain chutzpah. The company has however had some support here; Forrester, for example, provides some numbers that can be used to support the contention that Microsoft flaws are less severe, less numerous and fixed faster. And although there's a general readiness among users to believe that Windows is a security disaster area, there's also a reasonable amount of support for the view that Linux would get just as many security issues if it had anything like Windows' user base.".
