XM Satellite Radio

June 02nd, 2009

XM Radio LogoIn April 2009, I did what I thought I would never do, namely walk out of an auto dealer’s lot with a brand new vehicle. With the economy being more like a depression, and the automakers desperate to make a deal, I thought this was an excellent opportunity to get what I wanted. In this case, it was a new Chevy Silverado Crew Cab Pickup. The new truck is simply great and I must admit that driving a new vehicle does give you a certain smugness, which took me a month to get over. I will try to post something in the near future about the new truck, but this post is about and why I ended up keeping it. Most new GM vehicles come with a 90 day trial of XM Radio and the Silverado was no different.

The GM Factory Deck

First up is the GM deck. In my case, the GM deck acts as both a regular AM/FM receiver and XM satellite receiver. It also performs a third function, which is to perform some OnStar functionality, such as Turn By Turn directions and display messages for your built-in satellite phone. After a while, you will notice that the deck is pretty simple to operate. The main features are that it has a built-in equalizer for sound adjustment and six menus of favorite stations (you can designate both XM and regular radio stations within the same favorite menu list). The deck does not have an LCD display and so is not stunningly hi-tech in appearance.

XM Stations

Unlike regular radio, XM has no commercials for most of its stations and interruptions are very minimal. The disc jockeys are not annoying either and are for the most part fans of the music they play. My all time favorite channel is The Boneyard, which plays classic rock music including some metal bands like Metallica, Black Sabbath, and Iron Maiden. In the past three months, I’ve listened to some songs I have never heard before. The variety is amazing, but even classic rock stations will run into some repeats from Billy Squire and Judas. Overall though The Boneyard tries not to repeat the same songs.

Moving on, there are other stations like Hair Nation channel 41 which plays hairband rock music from the 80’s, Liquid Metal channel 42 which is home to heavy metal only, and variety stations like Classic Rewind and Rock@Random. Hair Nation plays a little too much White Snake for my tastes, but hey, you gotta love some Cinderella and Motley Crew, right?

For non-rockers, there are other genres too, like Country, Classical Music, Soul, Disco, and Alternative 90’s rock which I still don’t consider to be real rock music. Music wise XM has pretty much everyone covered. The one glaring problem I see with XM is the lack of Latino music. There is Caliente, but that is just one station and so there seems to be a lack of serious Spanish music variety on XM. You would think they would have at least three Spanish stations, but nope they just have one.

Other than music, XM covers Sports, Weather, News, Political Commentary, and Comedy. If you have kids or just want to block certain channels from your receiver, you can do that by going to XM’s website and setting up filters for your account.

Is it Worth Paying For?

Right now the price is pretty reasonable. The cost starts at around $15 a month for a basic lineup. Reception in my GM vehicle is also excellent unless I am in a parking garage or in a drive-thru that happens to block reception. In Iowa, my experience is that XM reception is better than FM radio. Note that on extremely cloudy days you might run into reception issues, but even with Iowa’s mostly cloudy days, this does not seem to be a problem very often.

It is quite hard to go back to regular FM radio. With XM, I don’t feel the need to plug-in my iPod or carry CDs anymore. I can just sit back and turn on XM and rock out whenever I feel like it, and now isn’t that why you have a radio in your car in the first place!

EveryDNS Setup for DD-WRT

February 13th, 2009

It is possible to setup dynamic DNS with your router. DD-WRT, a free Linux-based firmware for several wireless routers, offers multiple dynamic DNS setups. In this example I have chosen to use DD-WRT with the free dynamic DNS service EveryDNS. Although DD-WRT does not specifically list EveryDNS as an option under the Setup – DDNS section, you can easily add it in the following manner:

DD-WRT DDNS EveryDNS Setup

  1. Login into the DD-WRT control panel for your router and choose Setup – DDNS.
  2. Fill in the following values:
    • DDNS Service = Custom
    • DYNDNS Server = dyn.everydns.net
    • User name = your username
    • Password = password for you account
    • Host Name = your domain name
    • URL = /index.php?ver=0.1&domain=your_domain_name
  3. Save and Apply your settings.

If you are not using EveryDNS, you can find instructions for other dynamic DNS providers on the DD-WRT Wiki.

Dell T105 CPU Upgrade

February 02nd, 2009

AMD OpteronLast year I broke down and bought a Dell PowerEdge T105 Server because it was relatively inexpensive and I needed a new Windows box at home. While it came out of the box with a modest Dual Core Opteron 1.8GHz cpu, I definitely wanted something faster in the future. Well the time came this week and I found the AMD Opteron 1224SE 3.2GHz on Newegg.com simply too good to pass up. At $115.99, the price is just right for an AMD based processor. This was an OEM processor, so it came as is, no heatsink or instructions included.

The PowerEdge T105 is pretty easy to upgrade. Since this was a processor upgrade, make sure your T105 Server has the latest BIOS update from Dell, if it needs it. Dell provides no documentation that I could find that the 1224SE is supported or not, so I had to gamble that it would work for me. You will want to look the Dell manual for uninstalling the Dell heatsink if you are haven’t removed the heatsink before. There are two screws you will need to remove and then plastic case surrounding the heatsink, comes loose when you lift it up and back. Once you have the heatsink off, you might want to clean it off and apply a small amount of Arctic Silver to the new cpu. In all the upgrade took less than 20 minutes.

So far the differences in speed are apparent when launching applications, however if you have not upgraded the memory, you probably should do that too. With the 8GB of RAM and Dual 3.2GHz Opteron the server feels a lot more responsive than the stock configuration from Dell. You can get the memory relatively cheap from Shop.Kingston.com and cheap AM2 processors from Newegg.com.

Wireless Networking Does Not Work

January 29th, 2009

Linksys RouterYou ever work on something for so long that you start to think someone must be playing a joke on you, or at least laughing at you? This is the exact feeling I have when dealing with wireless networking. On the one hand, not having to run wires through your house and worrying about your dog or children tripping over them is nice, I am not sure the trade off is worth it. Let us begin with a simple home wireless network router and how the labyrinth gets complicated so easily can sometimes amaze you. Immediately you are encountered with a list of concerns that you never had with wired Ethernet, such as to secure the router or not? Any technical person would tell you that you need to secure it to prevent your neighbor’s kid from downloading all sorts of naughty things, because if you do not do this, ultimately you are legally responsible for anything that gets downloaded through your $50 router! Next you have to worry about signal interference, cause you do not want your wireless router to interfere with any cordless phone or other wireless router that your neighbor may have. Did I mention your microwave hates your router too?

Say you figured out all of that stuff and you are happy with your router security and your router’s placement. Now comes the fun part, which is having to one by one connect all your devices to your router and make them all play nice with each other. First come the desktop machines, then the laptops, and if you have mixed Windows and Macs it makes it more challenging. On older Windows XP machines, you end up cursing Microsoft for making this harder than running a marathon, and on the Apple side, you wonder if Apple documents anything at all with industry terms, it is as if Apple has to rename everything to an Apple friendly name just for the sake of being different!

If you survive all of this configuration and troubleshooting, you then are confronted with your son or daughter asking you if you can fix it so their Nintendo DS and Sony PSP can access the Internet. Oh, you probably need to fix it too so that the Playstation 3 can connect too. Overall, by this time you figured out that the easiest of all was the network printer, but for whatever reason the PS3 still can’t see your printer.

Lessons Learned

I am sure the Steve Jobs digital lifestyle works, if all you have are Apple products, but in reality wireless networking is a test of patience. What you suddenly discover is that networking is too complicated for normal people to do. With every device you add to the network, the security model tends to suffer and you see that inexpensive products like the Nintendo DS just do not support the latest security methods such as WPA2 and AES. You almost need two wireless networks, a highly secure one and a very open one that has limited functionality for all those devices that cannot connect to anything secure.

Seagate Firewire Drive Problem

December 01st, 2008

Apple Disk UtilityRecently, I had the opportunity to diagnose a problem with an external Firewire drive and Mac OS X. The drive would no longer mount on the OS X desktop and the only place you could see it (other than Terminal) was in Disk Utility. If you ran Disk Utility – Verify or Repair, the message: invalid content in journal would appear. The fix to make it mountable again was to do the following in Terminal.

The first command gives you a list of all drives and in the right most column, you will need to identify what the Identifier Name is for your volume. Once you have that, run the second command and substitue the IDENTIFIER_NAME with the correct Identifier Name for your volume.

diskutil list
/System/Library/Filesystems/hfs.fs/hfs.util -N /dev/IDENTIFIER_NAME

Example: disk0s2

If it successful, this will mark the disk as no longer Journal, so you can now shutdown the Firewire drive and then unplug it. Wait a minute or so and then start it back up and plug it back into the Macintosh and then you should be able to see the drive mount again.

This allowed me to mount the drive again, but I believe there is still a problem with this drive, so my recommendation was to backyp the drive right away and then reformat it and exchange it for a new drive. I am not sure if the problems with the 1.5TB Seagate drives in RAID configuration apply to other Seagate drives as this one was a 1TB drive, but you never know.
