In XBMC Eden, the power to the USB ports is cut when S3 is entered. It is therefore impossible to wake the system using the MCE remote or any other device connected via USB.
The following two fixes in combination resolves this problem:

Samba is not included with XBMCbuntu (at least in 11.10), so first we have to install it:
sudo apt-get install samba
Open Samba’s configuration file in an editor
sudo nano /etc/samba/smb.conf
Scroll down to the bottom of the file and add the following sections, which will create a public share with read/write access without password validation:
[global]
workgroup = Workgroup
netbios name = XBMC
server string = XBMC Server
log file = /var/log/samba/log.%m
max log size = 50
map to guest = bad user
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
local master = no
dns proxy = no
[public]
path = /media
public = yes
only guest = yes
writable = yes
force user = xbmc
The above configuration example shares everything under the /media directory in a folder called “public”. The “force user” property must be set to a user with write access to the directory being shared. All files and directories will appear to have been created by this user.
Run “testparm” to check if your Samba configuration is parseable. For configuration changes to take effect, the Samba daemon can be restarted with
sudo /etc/init.d/smbd restart
The following screenshot shows my XBMC box sharing the /media directory which contains mount points for two harddrives (ingeniously named according to their capacities…):

These are the steps I took to flash a Linksys E2000 router with a DD-WRT firmware.
Background information
http://www.dd-wrt.com/wiki/index.php/Linksys_E2000
http://www.dd-wrt.com/wiki/index.php/Installation
Steps Taken
– 30/30/30 Reset
– Upload dd-wrt.v24-18024_NEWD-2_K2.6_mini-e2000.bin via Linksys firmware upgrade page from ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2011/12-20-11-r18024/broadcom_K26/
– Wait 5 minutes after upload completed.
– Web interface for DD WRT appears.
– Do a 30/30/30 reset again.
– Wireless > Advanced Settings enter 50 in the Tx Power entry. This should make for less Tx/Rx Errors and help the unit run cooler.
General:
– Initital DD WRT firmware flash must be a trailed build. A trailed build has “*e2000.bin” in its name. Following flashes must have “*e2k-e3k.bin” in their name.
Sometimes you run into a test that works when run from within Eclipse but not from the command line. To debug the failing test from Eclipse, you can configure the Junit ant task to accept remote debugging sessions.
This can be done by adding the following lines to the junit task:
<junit fork="true"> <!-- For remote debugging from Eclipse --> <jvmarg value="-Xdebug" /> <jvmarg value="-Xnoagent" /> <jvmarg value="-Djava.compiler=NONE" /> <jvmarg value="-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y" />
This will make the task wait for an incoming debug connection on port 8787. It is necessary to have the fork attribute on the junit task set to true, because the jvmarg values can only be given to a starting Java virtual machine.
Problem: You have an XML structure in a JQuery object and now you want to extract a string with the raw xml.
Solution: Use the XMLSerializer class. This class provides methods for serializing DOMs and nodes into text or byte streams. In our case, we will call the serializeToString(data) method:
new XMLSerializer().serializeToString(xmlDoc);
find
Find all files from current directory and subdirectories
find . -name '*.doc' -print

Casting the array obtained by invoking the toArray() method on a collection yields a ClassCastException.
For example:
String[] strings = listOfStrings.toArray();
will throw the ClassCastException.
The trick is to use the overloaded version of toArray(), which takes an array as parameter. This the javadoc description of the method
toArray(T[] a)
"Returns an array containing all of the elements in this list in the correct order; the runtime type of the returned array is that of the specified array."
The solution is therefore to do this:
String[] sv = (String[])v.toArray(new String[0]);
Lightrooms data files can roughly be put into two categories: The catalog file(s), which contain meta data about your images such as their location and the actual image files.
Lightroom does not permit having the catalog files on network attached storage, so you will have to keep those on your workstation. However, you can choose to have Lightroom backup your catalog files to the NAS so they are stored together with your images. This can be configured by going into Edit > Catalog Settings in Lightroom.
The following steps explain how to move your images from your workstation to a location on the NAS.
If something goes wrong you can always replace the catalog file with the backup from step 1 and rename the images_OLD back to using your local image folder.
As to be expected, there is a slight performance drop, by having the images on a network share instead of a local harddisk. In order to quantify the difference I picked 10 test photos (RAW) and measured the the time it took to zoom in on the image in Library mode. Zooming in on an image forces the actual image to be loaded into memory instead of just showing a preview.
Not much of a difference and hardly noticable. I have not timed any other operations, but it appears, that the main loading happens only once. I.e., there is no lag when cropping or fixing white balance, since the image has already been loaded into memory.
