I've had this LCD for a number of years and never got around to figuring out how to drive it. I'm collecting what information I can.
Serial 16×4 character LCD / LED Backlight Green

Enabling Oracle SQL Advisor
This error message from Oracle SQL Developer was bugging the crap out of me
DECLARE * ERROR at line 1: ORA-13717: Tuning Package License is needed for using this feature. ORA-06512: at "SYS.PRVT_SMGUTIL", line 52 ORA-06512: at "SYS.PRVT_SMGUTIL", line 37 ORA-06512: at "SYS.DBMS_MANAGEMENT_PACKS", line 26 ORA-06512: at "SYS.DBMS_SQLTUNE", line 651 ORA-06512: at line 4
Turns out the solution is simple

SqueezePlay on the Joggler
The Joggler makes an excellent UI for the HomeAutomationHub. However the xapFlash application isn't the only worthwhile Joggler app.
I'd been meaning to sort out my digital music collection for a while and recently purchased an HP Microserver to host all the files. Having pulled these into one place, the next thing to think about was howto play the music. A while back, I looked at the Logitech SqueezeServer - a software indexer and media content server. This is freely available (Logitech no longer manufacture 'player' devices) and seems to have a decent range of third-party players.
In particular, there is a port of the Logitech SqueezePlay available for the Joggler. SqueezePlay is designed to work with a SqueezeServer. The folks at BirdsLikeWires have done a lot of work on this Player port.
The install is straightforward - good instructions on this at the above link. Once installed, you have a new icon on the Joggler desktop.
Next thing to do is to create yourself an account at mysqueezebox.com - this allows online management of all of your players.
Then, on the Joggler, fire up SqueezePlay & enter the details of your new account via the Settings/Registration and Settings/mysqueezebox page. Now the fun starts …
You can access your music library in a variety of ways. I was especially keen to be able to use my android phone as a 'remote control'. The 'Logitech SqueezeBox Controller' app is freely available from the Google Play store. It works really well.
Next, I wanted to have a 'Player' on my Android phone (so I could wear a headset and wander around). There is a 'paid for' app that does the job well - it goes by the name of SqueezePlayer. This installed and worked seamlessly. With a bit of dyndns type work, I could access my media library via 3G as well as WiFi.
A really neat feature is the ability to 'synchronise' a number of players. The synchronise facility isn't available on all Players (as it needs specific capabilities on the target platform) but it IS implemented on the Joggler. From the 'settings' menu, select 'sync' to see a list of other players. Select the players that you want to sync with. It works surprisingly well … no sign of any delay between the players (even the slightest delay can be most annoying). Any player (or controller) can control all 'synced' players - plenty of possibility for whole house audio here.
ex475 with Linux (fedora 20)
You need a video cable for this as it requires a bios tweak
I got fed up with trying to figure out how to install WHS2011 onto my ex475. So I bit the bullet and just installed a linux distribution.
- Pull bottom drive from your ex475
- Put drive into spare USB container
- Create a VM using VM workstation and point it at a physical disk (Advanced settings for this)
- Install Fedora 20.
- Put drive back and boot it up
A couple of things I had to do. Disable Network Manager (NM) controlling the interface.
/etc/sysconfig/network-scripts/ifcfg-eth0
UUID="b65270ab-2b79-473d-8dce-942908383ff2" NM_CONTROLLED="no" BOOTPROTO="static" DEVICE="eth0" ONBOOT="yes" IPADDR=192.168.1.20 GATEWAY=192.168.1.1 NETMASK=255.255.255.0
To resolve the slow disk startup issue required tweaking a BIOS setting. You'll need video cable http://www.mediasmartserver.net/forums/viewtopic.php?f=6&t=8066 just the bare minimum VGA only will do as keyboard/mouse on USB are fine.
- Change from 4P(IDE)+4S(RAID) to 4P(IDE)+4S(IDE)
The video switches to a small font I prefer to see the BIOS font and all the startup messages - /etc/sysconfig/grub

Same old boring processor. I never bothered upgrading this.

File transfers are significantly faster than when it was running Windows - I can sustain ~83 MB/s on a 40Gb file.
