Hello There again.

It's been a long time since I  published something in this blog. 

I do not have my old ASUS from the posts of 2011.

I will be doing some code experiments here and try  to show some interesting code

How to make the sound card work in asus N53 j laptop

My issue was that the sound card worked with headphones but not with the internal speakers my laptop has.

After some Google search I came across with this blog: http://blog.tersmitten.nl/archives/1082/comment-page-1#comment-3371

I did what the author said there but get no results, but this gave me some clues where to find.

Then I looked at https://help.ubuntu.com/community/HdaIntelSoundHowto and followed all the guidance this documentation has.

This how to assumes you have the latest alsa drivers installed.
So, what i did was:

• Open the file alsa-base.conf located in:
  

  /etc/modprobe.d/

sudo gedit /etc/modprobe.d/alsa-base.conf

• Then add the next two lines to the end of this file:

options snd-hda-intel model=auto
options snd-hda-intel probe_mask=1

Workaround:

• instead of the two lines above add only :

options snd-hda-intel model=auto position_fix=0

to the end of this file

• save the file, close it, reboot yor computer

That's it.

How to install the java JDK

Hi all, I am going to start explaining what I did to install the oracle/Java jdk

You can do this if you want to have total control of your Java jdk and learn how the package manager creates all of its configuration.

this was tested on ubuntu 10.10 x86_64 and with the 64 bit version of Firefox
so here it goes :)

Notes: be sure to unistall openJDK or any JRE/JDK you have previously installed


1. Install java

• Download official jdk .bin file (jdk-6u24-linux-x64.bin) from the java official site

• create a folder under /usr/local/src named tmp :

mkdir /usr/local/src/tmp/

• move the .bin file to the folder you've just created

• go to that folder, then type:

chmod +x jdk-6u24-linux-x64.bin

this will make the.bin file into an executable file

• then execute the file:

./jdk-6u24-linux-x64.bin

this will create a folder named jdk1.0.6_24/

• move the folder jdk1.0.6_24/ one level up :

mv jdk1.0.6_24/ ../

• now you have two new folders under /usr/local/src:

1. tmp/
2. jdk1.0.6_24/

• erase the tmp folder along with the .bin file inside:

rm -r tmp/


2. Tell the system where to find java
In ubuntu, under your home directory, there is a file called .bashrc to see this file:

• go to your home folder by typing '~' (without the quotes) in the console

• then type ls -a, this will list all files including hidden files .bashrc is a hidden file because it has a '.' preceding its name
  

• open this file with gedit or your preferred text editor :

gedit .bashrc

• add the following lines at the end of this file:

JAVA_HOME=/usr/local/src/jdk1.6.0_24
PATH=$JAVA_HOME/bin:$PATH

CLASSPATH=$JAVA_HOME/lib

to test what we did before:

• Reboot your pc, then open a terminal and type

java -version
It should appear some info about the java virtual machine


3. link java to your web browser (firefox) (taken from http://sites.google.com/site/easylinuxtipsproject/java#TOC-Removal1)

• remove the IcedTea plugin, if it has been installed.

sudo apt-get remove icedtea6-plugin

• close Firefox

work around 1

• go to the firefox plugin folder, mine is in

/usr/lib/firefox/plugins

• create a symbolic link to the file jdk1.6.0_24/jre/lib/amd64/libnpjp2.so

ln -s /usr/local/src/jdk1.6.0_24/jre/lib/amd64/libnpjp2.so

• open firefox and type in the address bar:

about:plugins

it should appear the description of the java files firefox uses


if it doesn't work here's the second option but first remove the symbolic link you created before

workaround 2

• go to your home folder:

cd ~

• execute the following command, in order to create a certain folder (if it doesn't exist already).

mkdir ~/.mozilla/plugins

• go to the folder you've just created:

cd ~/.mozilla/plugins

• Now you can install the plugin, by creating a symbolic link (you tell Firefox, where the plugin is located).

ln -s /usr/local/src/jdk1.6.0_24/jre/lib/amd64/libnpjp2.so

• open Firefox and type in the address bar

about:plugins

it should appear the description of the Java files Firefox uses


One good page to test if Java is enabled in Firefox is: http://www.myphysicslab.com there you can find some simulations written in Java and some applets that run through your installed Java plugin


Hope you enjoy your new fresh installation of Java jdk, see you next time
