Sometime during the night the power went out and the server didn’t come back up till I started it this morning. Even then there was a problem with my caching plugin, after I updated that I was finally able to get everything back up and working.
Well if the EU (European Union) has their way then you could have Firefox, Chrome, Opera, and Safari installed by default on a newly purchased PC. The EU claims Microsoft is hurting the browser competitors by bundling Internet Explorer with Windows; you think? The other option is to force a hearing on the matter. Which way do you think Microsoft will go?

Samba 4 which is still in development is the file sharing/logon service program used in Linux that looks to replace Microsoft AD (Active Directory) completely. Although some of the features of AD are available in Samba 3 it takes a lot of work to get these working. At work we’ve recently switched our servers over to Linux and use Samba as a simple logon/file server. It took nearly a month of work to get everything right. The biggest feature missing from Samba 3 is group policies, to work around this we have very long logon scripts. With Samba 4 group policy will be implemented that will make everyone who uses Samba with Windows clients lives easier. No release date has been set but the developers are contemplating releasing a version for those who just want to use Samba as an AD replacement.

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.
