Smart AC
A while ago, I received a letter from PG&E mentioning their Smart AC program. This program lets customers voluntarily let their air conditioning get throttled when there is a significant energy demand.
The box that is installed on the compressor, has a pager network radio receiver, and when it receives a signal from PG&E, it will throttle the AC back. It looks like it does it’s throttling by cycling the compressor on in 15 minute intervals, when the thermostat tries to turn the AC on. During this time, since the thermostat thinks that the compressor is on, the fan will still be running to help with the cooling of the house. Users also have the ability to opt out of the throttling in 24 hour periods.
In our case, I don’t think that we will be affected, as we hardly have the AC on. But, I figure that we can do our part, and if turning off our AC in 15 minute intervals, can prevent a black out, we can join the program.
Upgrade ext3 to ext4
I was interested in upgrading my laptop’s hard drive to ext4 from ext3. Ext4 offers some features over ext3, and I figured that since I upraded to Kubuntu 9.10, I might as well upgrade the file system.
This blog post describes the steps needed to upgrade from ext3, without formatting the hard drive.
Unfortunately, I didn’t unmount it before running through the steps, and I didn’t pay attention to the fsck warning. My partition did get corrupt, and I decided to reformat and do a clean install. (At least I am able to create an ext4 partition, and it is nice to do a clean install every once in a while.)
Luckily, I was able to restore all of my data, since I have been backing up my files on Linux with JungleDisk. Also, I am able to restore my Windows VMWare image, since it is backed up to my Windows Home Server.
Skype video with Ubuntu 9.10
I had to reinstall Kubuntu, for a reason that I will write about later, so I needed to reinstall skype. When I downloaded and tried the 2.1 beta, I wasn’t able to get video to work.
I was able to use the instructions on this page to get video working. You need to launch skype with the following command line:
LD_PRELOAD=/usr/lib/libv41/vl1compat.so skype
Netflix and Windows Media Center
For some reason, within the past couple of days Netflix streaming in our Vista Media Center stopped working. The interesting thing is that playback worked from the browser and from PlayOn, both from that computer. Nothing that I did solved the problem. I was getting so frustrated that I wanted to just get a Roku HD, so I wouldn’t have to deal with software configuration anymore.
As one last ditch effort, I wanted to upgrade to Windows 7 to see if would fix Netflix streaming. If it didn’t, I would go get a cheap Comcast DVR, and a Roku HD box for each TV.
The upgrade to Windows 7 went smoothly, and I am now able to stream Netflix content. Also Windows 7 Media Center adds other Internet TV sources. In addition to those things, the redone UI is very nice.
Disk Space on WHS System disk
I have been having some problems with my Windows Home Server. The 20GB system disk has been filling up. When this happens various programs get unstable (Can’t connect to the console, Squeezebox Server crashes, …)
I RDP’d into the server and then took a look for where the disk space was going. I found that the log files from the DynDNS client were taking 8GB of space. Once I deleted the log files, everything started working well again. I will try to see if I can disable the logging the client.
Multiple accounts with Live Mesh
I am the tech support person for our family. For my wife’s grandmother, I installed a Windows Home Server in her house. One of the features of the Windows Home server is that it is a proxy to allow you to RDP into the other computers on the network. The problem is that this only works for the computers that have the RDP server enabled. (i.e. Windows Vista Ultimate…)
Windows Live Mesh has a similar feature, but it doesn’t have the requirement that the windows installations has its RDP server enabled. Live Mesh’s implementation requires that the Live Mesh client is installed on the computers that you want to access, and the computers that you want to do use to access them. Once you have the software installed, you need to log into Microsoft’s live server on each computer. Then from any computer signed into a Live Mesh account, you can connect to any other computer also signed into that account.
The problem is that this doesn’t really work well with multiple accounts. For example, I have a Live Mesh account, and normally am logged into it when I log into my Windows account. When I want to help out family, I need to log out of my account and then log into their account. Ideally, Microsoft would add the ability for a Live account holder to be able to grant access to another Live account for a particular computer.
