As you can tell I’ve updated a few parts of my blog, namely the nice tabbed interface for the sidebar, and going with one sidebar split into two columns at the bottom. Tell me what you think of it, I always appreciate feedback.

InfoWorld has an interesting article about a new upcoming trend in datacenters; using DC power instead of AC. The whole idea behind this being is that as much as 50% of the energy consumed in datacenters is wasted in the AC to DC conversion. The typical path of electricity is AC from power company to racks, then converted to DC then back to AC by a UPS, then in the server power supply converted back to DC for the internal electronics. Each conversion loses a little energy but multiply that by the amount of servers and the loss starts to add up.

The solution is to forget AC all together and run DC directly to the servers. HP, IBM, and Sun are all starting to make their servers with optional DC power supplies and trying to get a standard wiring, voltage, and connector ratified. This move will help companies with limited space expand their datacenter. This is because the energy lost in the conversion from AC to DC and back is released as heat, so the fewer conversion the less cooling needed the more servers you can pack into a datacenter.

AMD’s new 45nm processor the Phenom II looks to be set to take the on Intel again. While being demoed for the press they were able to overclock the quad-core processor to 5Ghz using dry ice. It had been leaked earlier that 4Ghz was possible using on air but no reports have officially come out on that. It was also reported that the chip hit 6Ghz using liquid nitrogen, which I don’t know about you but I don’t have an abundance of.

Thanks to Otto for this great post on the heads up on the new comment system for WordPress 2.7. After I read this I decided to get ahead of the curve and switch my Techozoic theme over to the new threaded commenting. I decided to take it a little further and separate pings and trackbacks from regular comments. At first this wasn’t working but after a quick email to the wp-testers list Ryan whipped up a fix for it. Anyway I figured I would explain how I did this. I continue below.

Unlocking Locked Network Files

Although this one is short I think it could be very useful to those that need it. It doesn’t come up often but when it does it’s extremely frustrating.
