MythTV


MythTV is a bear to install and setup but it is well worth the hassle. I chose to use the "Add to Ubuntu" option of Mythbuntu on the frontend and backend. I tried the full Mythbuntu distribution but didn't like that as well as the "Add to Ubuntu" option.



I'm using my Dell M140 laptop as the front end. I plan to look for a suitable front end in a few weeks. I want something small, quiet, and compatible with my Samsung TVs (models LN-T4661F and LN-32A330J1D). I have a single Hauppauge HVR-1600 dual tuner video capture card in the backend. The analog tuner is connected to my Comcast cable TV service and the digital tuner is receiving over-the-air ATSC HD. I've used my PS3 as a front end too using the UPnP option. The PS3 works well as a frontend but it is not as nice as the Myth frontend interface.



The Myth TV configuration options and variations are many. It is overwhelming at first. Getting the capture card recognized and setup is tricky. Getting the frontend to talk with the backend took some time for me to figure out. All and all it is just a matter of getting your hands dirty with allot of trial and error. After hours and hours of reading and configuration it all starts to click. Wireshark the packet sniffer was helpful in understanding the communications between the frontend and backend.


Give MythTV a try. Tivo, your days may be numbered in my house.

Google Calendar Views Application

Google Calendar Views logoAs of this writing I have over 90 Google calendars that I view several times a day. I found myself spending more time than I prefer toggling calendars. To save time I wrote a Java Webstart application called Google Calendar Views. With this application, you can create, save and apply views of like calendars. You can specify whether each calendar is hidden, selected, and its color. Once you add your Google accounts and setup your views you can quickly swap views. All account and calendar information is written locally to an encrypted embedded JavaDB (Derby) database on your computer. Read more about it, or view the YouTube video below and then give it a try.

Sun Ray Thin Client Comparison

I've used 3 Sun Ray thin clients. They are Accutech Gobi 8, General Dynamics Tadpole M1400 and Sun Ray 2. All of the clients work well. Of the two notebooks I prefer the Tadpole M1400 over the Gobi 8. The M1400 has a much better configuration UI and the screen resolution is higher. I wish the M1400 could do without the internal fan. It kicks in every few minutes. See the Google spreadsheet below.

Sun Ray 2 Wireless Improved

A few weeks ago I wrote about connecting my Sun Ray 2 wirelessly to my home network. I used a Linksys WAP54G which was really bulky and required a power brick. I ran across someone in the Sun Ray Users mailing list using a D-Link DWL-G730AP. So I ordered one. It is smaller than a pack of playing cards and is USB powered. This really makes for a much better solution. I was going to velcro it to the side of the Sun Ray but I thought better of it. There are some air vents that would have been blocked. The D-Link fits nicely under the Sun Ray power cord in the back.

Hello Says Goodbye

Although I didn't use it much, I'm sorry to see Hello go. It was a quick and easy method for sending full resolution photos to friends and family. I wonder why Google is pulling the plug?

Sun Ray 2 Wireless

I have configured a Sun Ray 2 in my bedroom without running any CAT5 Ethernet cable in my walls.

I used a Linksys model WAP54G wireless access point configured in AP Client mode. It talks wirelessly to my Linksys WRT54GS router which is connected to my AT&T DSL Internet connection. I am using the Sun Ray's built-in VPN client to talk to the corporate firewall at work.

Of course the Sun Ray 2 is silent so it makes a good sleeping partner. :)

The Silence of the Sun Ray 2 Thin Client


You never realize how noisy something is until you turn it off. I'm using a Sun Ray 2 thin client at home over a VPN connection. I never realized how loud my PC disk drives and fans were until I started using a Sun Ray thin client. The silence is welcomed and appreciated. Now I have to replace my LCD monitor. It has a low buzz that I never detected before.

Working Comfortably


PS3, Ubuntu, and Samsung. A great combination for a graying, balding, eyesight weakening old fart like myself. Happy computing.
