Ubuntu - hdmi, video, webcam

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)

Eclipse Too many open files fix

Solution:
Fix is adding the following entry (to increase the open file count)
in configuration/config.ini
osgi.bundlefile.limit=100

Problem:
I got this exception

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

Unix command to uncompress

Compressed UNIX tar archives (typically tar.gz or .tgz extensions) can be extracted in a single command. This is faster and works with less disk space available.


To extract the compressed tar archive target.tar.gz into the current working directory with:

gzip -dc target.tar.gz | tar xf -

If the file was compressed with bzip2 (i.e., .tar.bz2), you can substitute the bzip2 command for gzip.

If the archive was compressed with the UNIX compress command (archive ending in .Z) you can use:

zcat target.tar.Z | tar xf -

Eclipse design time didnt handle trinidad tags properly (no UI rendering for tr components),but it worked fine.

What I needed was to select rows in table using radio button option. It looks simple functionality but always it created problem. I remember doing some custom java script implementation to handle it, then we had difficult time even in .Net development. Now in java also we spent few days in fixing some very basic issue.
It is not technology which need to be blamed all the time. if we started with the formal instructions, it would have been very easy for us.

VMWare Server 2.0 on Ubuntu - Guest windows 2003 server

I had a need to refresh my M$ Knowledge and tried to do that.

As my laptop (inspiron 1525) runs with Ubuntu, I have downloaded vmware server 2.0 (available for free from vmware site). And then installed windows 2003 on it.

Few issues and how I resolved it.

1. default windows desktop size was very small.
fix: increase the resolution, and it made my windows desktop to use full laptop screen.
2. Login problem:
I was not able to send Ctrl+Alt+Del signal after installing it, but then some one on internet suggested to try
Ctrl+Alt+ PrintScrn combination, it worked.
3. Keyboard problem: Del button and arrow keys were not working. probably some other keys were too not working. down arrow was behaving as if it is the windows button, and backspace was working as del button. Yes I had no way of backspacing my text.

Fix: I followed this link and found the fix working.

I tried solution 3 mentioned in the blog post.
i.e login as root and execute 'echo "xkeymap.nokeycodeMap = true" >> ~/.vmware/config'
It worked for me. Yes it is not the typical sudo. sudo didnt work for me (also mentioned in the article). Opened new shell and logged in as root. then executed this command.

Surprising, it worked. now I am very much comfortable in the vmware win2k3 image.


Yes, as it is free ware, vmware might have left some known issues along with it. But then I am able to solve the issues in front of me.

Now, I can stick to Ubuntu and occassionally use windows by vmware server web console for specific needs.

I am happy.

JOSSO 1.8

Today I tried playing with JOSSO, I spent around 4 to 5 hours. Wanted to setup JOSSO with NTLM authentication, but not successful yet.

Here is the log of what I have done.

Follow instructions from
http://www.josso.org/confluence/display/JOSSO1/Quick+Start
there is some confusion here, as the article talks of using commands to install josso, but the downloaded file is not having the stuff related with the documentation.

Download Josso 1.8 release from sourceforge.net download lcoation.

http://sourceforge.net/project/showfiles.php?group_id=116854&package_id=129496&release_id=653379

you can download the .tgz file which is around 42MB. this contains josso-gsh shell, which can be used to deploy the war file (documents on josso confluence site use this shell to deploy, it took a while for me to identify which file has this gsh file)
gateway install --target "D:/servers/Tomcat 6.0" --platform tc60


Either you can do this or download the tomact version and use it directly/build from source and use it.


in case if you need any further information best option is to google and if the josso site pages are not coming properly (in my case its getting timedout) then read the google cache.

As the 1.8 release happened almost a week back, we might face problems in setting up things propely, more help might come into internet in the comming weeks.

Open source alternatives for visio

As I am moving away from use of microsoft softwares, I was trying to find a proper alternative for visio, the famous microsoft modeling tool.

There seem to be 2 of them as proper alternatives(dia and drawing of open office), but dia leads the way because of the similarity with visio and certain special objects which make it better in casual designing. http://projects.gnome.org/dia/.

Check the URL for more details. It is a wondeful contribution by Free Software Foundation.
