Remove all the Java related packages on Linux Mint 14

I have just installed Linux Mint 14 and wanted to install my own Java environment. Quick search brought me to this thread http://askubuntu.com/questions/84483/how-to-completely-uninstall-java/185250#185250, so this post is just a copy my own further needs :-)

1) Remove all the Java related packages (Sun, Oracle, OpenJDK, IcedTea plugins, GIJ):

sudo apt-get update
apt-cache search java | awk '{print($1)}' | grep -E -e '^(ia32-)?(sun|oracle)-java' -e '^openjdk-' -e '^icedtea' -e '^(default|gcj)-j(re|dk)' -e '^gcj-(.*)-j(re|dk)' -e 'java-common' | xargs sudo apt-get -y remove
sudo apt-get -y autoremove

2) Purge config files:

dpkg -l | grep ^rc | awk '{print($2)}' | xargs sudo apt-get -y purge

3) Remove Java config and cache directory:

sudo bash -c 'ls -d /home/*/.java' | xargs sudo rm -rf

4) Remove manually installed JVMs:

sudo rm -rf /usr/lib/jvm/*

5) Remove Java entries, if there is still any, from the alternatives:

for g in ControlPanel java java_vm javaws jcontrol jexec keytool mozilla-javaplugin.so orbd pack200 policytool rmid rmiregistry servertool tnameserv unpack200 appletviewer apt extcheck HtmlConverter idlj jar jarsigner javac javadoc javah javap jconsole jdb jhat jinfo jmap jps jrunscript jsadebugd jstack jstat jstatd native2ascii rmic schemagen serialver wsgen wsimport xjc xulrunner-1.9-javaplugin.so; do sudo update-alternatives --remove-all $g; done

6) Search for possible remaining Java directories:

sudo updatedb
sudo locate -b '\pack200'

If the command above produces any output like /path/to/jre1.6.0_34/bin/pack200 remove the directory that is parent of bin, like this:

sudo rm -rf /path/to/jre1.6.0_34.

[SOLVED] No sound on Linux Mint 14 (Nadia) through ATI RS690/780 HDMI, Digital Out.

I have just upgraded my Linux Mint from 9 to 14 (Nadia) and first issue was with playing audio through

Card: HDA ATI HDMI  
Chip: ATI RS690/780 HDMI

Internet contains zillion of different solutions and neither one helped me until I found solution here https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/989671/comments/4. So, simply applying below steps solved my problem.

1) do

sudo vim /etc/default/grub

2) find the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

3) change it to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

4) do

sudo update-grub

reboot your system and enjoy!

Dump average file size within a directory

I had to provide some stats about feed files and found below time saving command here http://vivekjain10.blogspot.com/2008/02/average-file-size-within-directory.html

1:  find /some/dir -type f -name *.txt \  
2:  -print0 | xargs -0 ls -l | gawk \  
3:  '{sum += $5; n++;} END {print "Total Size: " sum/1024/1024 " MB : Avg Size: " sum/n/1024 " KB : Total Files: " n ;}'  
4:    
5:  Total Size: 55214.8 MB : Avg Size: 9792.17 KB : Total Files: 5774   

Change text mode to binary in CVS

If you accidentally checked in jar file in text mode, you can fix it as below:

1:  $ cvs update -kb path/to/your.jar  
2:  $ cvs commit -fm "Change substitution mode (jar from text to binary)" path/to/your.jar

/CVSROOTccess on cvs execution

This is a repost from http://www.whitesquaresoft.com/2006/07/15/cvsrootccess-on-cvs-execution/


I have often had the following issue when connecting to a CVS tree from the command line.

1:  $ cvs up  
2:  /CVSROOTccess /usr/local/cvsroot  
3:  No such file or directory  

The issue is one of line breaks, in that the actual error message that is supposed to be show is:

1:  Cannot access /usr/local/cvsroot  
2:  /CVSROOTNo such file or directory  

So this post is to help all those out there who have experienced the same issue.  I have found that the issue relates to the files in each of the CVS folders (Root, Entries, Repository)  depending on the client you use (in my case eclipse) to create the files, when you use the command line CVS it fails to interperet the files correctly and gets the wrong path.
I’d guess this is only an issue running CVS on cygwin under windows.  So now i’ve recorded it, all u have to do is dos2unix the files in all the CVS folders and it work a treat.

1:  dos2unix `find . -name Root`  
2:  dos2unix `find . -name Entries`  
3:  dos2unix `find . -name Repository`  

Will do the trick.

Send e-mail using CDO on GoDaddy's shared windows web hosting using classic ASP

Recently, a friend of mine told me that GoDaddy had to move his data to another server and after that his mail service stopped working. On old machine CDONTS was used, but on new machine CDO usage is required. So, I had to update code and now want to share it with you if you want to save your time. You just need to do "copy&paste' and test whether it is working or not.

1: <%
   2:
   3: '-----------------------------------------------------------------------
   4: ' file name: email-sender.asp
   5: ' sends email
   6: '-----------------------------------------------------------------------
   7:
   8: sub sendEmailText (mFrom, mReplyTo, mSubject, mTo, mCc, mBcc, mBody)
   9: dim cdoMessage
   10: dim cdoConfig
   11:
   12: set cdoMessage = Server.CreateObject("CDO.Message")
   13: set cdoConfig = Server.CreateObject ("CDO.Configuration")
   14:
   15: 'Modify the smtp server for the smtp server that your hosting uses (localhost for dedicated relay-hosting for shared)
   16: cdoConfig.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "relay-hosting.secureserver.net"
   17: cdoConfig.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
   18: cdoConfig.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
   19: cdoConfig.Fields("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
   20: cdoConfig.Fields.Update
   21:
   22: set cdoMessage.Configuration = cdoConfig
   23:
   24: cdoMessage.From = mFrom
   25: cdoMessage.ReplyTo = mReplyTo
   26: cdoMessage.Subject = mSubject
   27: cdoMessage.To = mTo
   28: cdoMessage.Cc = mCc
   29: cdoMessage.Bcc = mBcc
   30: cdoMessage.TextBody = mBody
   31: cdoMessage.Send
   32:
   33: set cdoConfig = nothing
   34: set cdoMessage = nothing
   35: end sub
   36:
   37: %>
   38:

and if you need to test it you can use below code

1:
   2: <!--#include virtual="/path/to/your/email-sender.asp"-->
   3: <%
   4:
   5: '-----------------------------------------------------------------------
   6: ' file name: e-mail.asp
   7: ' sends email using sendEmailText subroutine in email-sender.asp
   8: '-----------------------------------------------------------------------
   9:
   10: dim dateTimeNow
   11: dateTimeNow = Now
   12:
   13: sendEmailText _
   14: "from@somedomain.com", _
   15: "replyto@somedomain.com", _
   16: "Some nice subject", _
   17: "to@somedomain.com", _
   18: "cc@somedomain.com", _
   19: "bcc@somedomain.com", _
   20: "This message was sent using function from http://www.somedomain.com/test/e-mail.asp. If you got it, it is working! Sent at: " & dateTimeNow
   21:
   22: %>
   23: <h1>A test message using function have just been sent to you! Check for e-mail which contains <u><%= dateTimeNow %></u></h1>
   24:
   25:

Enjoy :-)
