I had problem with hdmi audio from ubuntu. Video is going fine to LCD tv through HDMI cable, but no audio.
Not sure if that is a problem with operating system or the multimedia softwares, but I found mplayer supporting audio as well.
Following line has fixed hdmi audio for me.
mplayer -afm hwac3,hwdts, -ao alsa:device=hdmi -channels 2 file
Skype, web cam:
Web cam was not detected by skype on ubuntu (9.04). After searching on internet, installed gspcs-source, followed by a system restart.
sudo apt-get install gspca-source
Skype recognized my webcam and when ever I am on voice call with my skype contacts, I am able to share video through webcam.
Kopete, yahoo IM problem:
Kopete was not able to connect to Yahoo server. fix I found on internet is add subdomain "cn" in the server name (account preferences). this "cn.scs.msg.yahoo.com" one worked for me. the default port of 5050 is same.
kopete is not able to detect webcam. It needs jasper conversion utility installed. I tried to to install libjasper-progs, but it seems replaced by another one in the ubuntu repository.
Here is the line that worked for me.
sudo apt-get install libjasper-runtime

Low volumne in ubuntu
If you are struck up with low volumn in Ubuntu (even in 9.04)
do the following:
sudo apt-get install gnome-alsamixer
after installing gnome-alsamixer run it, it pops up a UI. Increase the PCM value towards maximum.
try the sound now, you got it full right?

Linux /Ubuntu tomcat -> too many open files
Issue:
How do I set the maximum number of files allowed to be open on a system
scenario: I am running 3 war files of magnolia CMS on local tomcat, third one is not getting deployed properly because of the "too many files" opened.
Resolution:
The current setting for maximum number of open files can be viewed with the command:
ulimit -n
This number indicates the maximum number of files normal users (i.e. non-root) can have open in a single session. Note that for the root user, ulimit -n will sometimes output 1024 even after following the procedure to increase the maximum number of open files. This won't effect root's ability to open large numbers of files, as only normal users are bound by this value.
To increase the maximum number of open files beyond the default of 1024, two changes to the system may be necessary. In these examples, we will increase the maximum number of open files to the arbitrary value of 2048. All changes need to be made by the root user and users will need to log out and log back in before the changes will take effect.
1. Configure the system to accept the desired value for maximum number of open files Check the value in /proc/sys/fs/file-max to see if it is larger than the value needed for the maximum number of open files:
# cat /proc/sys/fs/file-max
If the value isn't large enough, echo an appropriate number into the variable and add the change to /etc/sysctl.conf to make it persistent across reboots. If the number is already larger than the value you wish to use, skip to step 2.
# echo 2048 > /proc/sys/fs/file-max
and edit /etc/sysctl.conf to include the line:
fs.file-max = 2048
2. Set the value for maximum number of open files In the file /etc/security/limits.conf, below the commented line that reads
# -
add this line:
* - nofile 2048
This line sets the default number of open file descriptors for every user on the system to 2048. Note that the "nofile" item has two possible limit values under the header: hard and soft. Both types of limits must be set before the change in the maximum number of open files will take effect. By using the "-" character, both hard and soft limits are set simultaneously.
The hard limit represents the maximum value a soft limit may have and the soft limit represents the limit being actively enforced on the system at that time. Hard limits can be lowered by normal users, but not raised and soft limits cannot be set higher than hard limits. Only root may raise hard limits.
When increasing file limit descriptors, you may want to simply double the value. For example, if you need to increase the default value of 1024, increase the value to 2048 first. If you need to increase it again, try 4096, etc.

vmware keys not working on vmware server 2.0.1
Keys like del, arrows are not working for me. ubuntu host and windows guest (xp,2003).
as per the forum suggestion, i have appended the following lines to /etc/vmware/config file (sudo credentials required on ubuntu).
xkeymap.keycode.108 = 0x138 # Alt_R
xkeymap.keycode.106 = 0x135 # KP_Divide
xkeymap.keycode.104 = 0x11c # KP_Enter
xkeymap.keycode.111 = 0x148 # Up
xkeymap.keycode.116 = 0x150 # Down
xkeymap.keycode.113 = 0x14b # Left
xkeymap.keycode.114 = 0x14d # Right
xkeymap.keycode.105 = 0x11d # Control_R
xkeymap.keycode.118 = 0x152 # Insert
xkeymap.keycode.119 = 0x153 # Delete
xkeymap.keycode.110 = 0x147 # Home
xkeymap.keycode.115 = 0x14f # End
xkeymap.keycode.112 = 0x149 # Prior
xkeymap.keycode.117 = 0x151 # Next
xkeymap.keycode.78 = 0x46 # Scroll_Lock
xkeymap.keycode.127 = 0x100 # Pause
xkeymap.keycode.133 = 0x15b # Meta_L
xkeymap.keycode.134 = 0x15c # Meta_R
well, a short cut suggestion was adding the following line alone.
xkeymap.keycode.135 = 0x15d # Menu
But I pasted both of them, not sure which one caused the fix.

FTP problem - Asci converted binary data
Recently I have taken all my data backup from ubuntu (laptop) to windows xp (desktop) to re-install OS in laptop. But ironically, filezilla ftp client transferred all images, pdf files, doc files in asci format.
As I read on this, ascii format means, it strips off 8th bit of every byte (this bit used for a special purpose flag). Restoration may not be possible.
See a sample, how I lost lot of data, print screen image of jetspeed tutorial page (in pdf)

Building portlets with Jetspeed 2.0
If you are looking at open source based portlet 2.0 development, then a good starting point could be jetspeed 2.0
You can create a maven project with the custom archetype of jetspeed by following similar syntax as below.
mvn org.apache.maven.plugins:maven-archetype-plugin:2.0-alpha-4:generate -DarchetypeGroupId=org.apache.portals.jetspeed-2 -DarchetypeArtifactId=jetspeed-archetype -DarchetypeVersion=2.2.0 -DartifactId=hello -Dpackage=com.springboard -DgroupId=com.springboard -Dversion=1.0-SNAPSHOT
You might come across an exception something like this
Caused by: java.lang.ClassNotFoundException: org.apache.jetspeed.tools.db.serializer.JetspeedSerializerApplicationImpl

the fix is that db plugin dependency is missing, I got rid of it by adding the dependency.
org.apache.portals.jetspeed-2
jetspeed-db-tools
${org.apache.portals.jetspeed.version}
Do not forget to add repository (might be optional).
