Howto Install Sun JDK with EE into Ubuntu 10.4

This tutorial is for Ubuntu 10.4 Beta. 10.4 full release is only next month. Well here you go.

  • Download Java for linux from the Oracle Sun website.
  • Download the 32bit version of libstdc++5 from here:
http://packages.debian.org/lenny/amd64/libstdc++5/download
Make sure you get the 32 bit version. It would seem that the installer for Java requires that you have a 32bit version of this library installed. I think this is for the installer GUI only.
  • Extract the library like this:
dpkg-deb -x libstdc++5_3.3.6-18_i386.deb libstdc++5
  • Copy the library into /usr/lib32
sudo cp libstdc++5/usr/lib/libstdc++.so.5.0.7 /usr/lib32/
  • Create a simlink to the file in /usr/lib32/
sudo ln -s libstdc++.so.5.0.7 libstdc++.so.5

Now you can install java like this:
./java_ee_sdk-5_08-jdk-6u18-linux.bin 
All done!

VirtualBox - AMD-V and KVM

I usually use the KVM on my linux host for Virtualisation. It's default with Fedora and I know it. Usually ...

Today I thought I would try the Ubuntu 10.4 Beta 1 on VirtualBox. I installed the latest VirtualBox ( version 3.1.6 ) and then had a crack at installing the Ubuntu 10.4 64bit. Of course an error came up saying that while AMD-v was enabled, it was not operational. After much googleling about, I found that the KVM modules were causing VirtualBox issues with access.

So a quick "rmmod kvm_amd" and "rmmod kvm" fixed it.

Next time I want to use KVM, I will need to re-enable these with, I suppose, a quick, "insmod kvm_amd" and "insmod kvm"

Freeview ( DVB-T ) Linux / Fedora in New Zealand.

I dont have anything fancy other than a fairly good CPU. Its an AMD Athlon(tm) 64 X2 Dual Core Processor 4000+.

I have an avermedia A800 DVB-T tuner from www.nicegear.co.nz

I DO NOT have a VDPAU enabled graphics card which can do on board H.264 decoding for me. That will be soon though. Need to save a bit of cash first.

I am in New Zealand so there are some special areas of concern that needed to be addressed.

Here is a very brief rundown of how i get free view working in my linux.

**** COMMENT ****
Here is a great website. I use this now for post processing.
http://quadpoint.org/projects/simplerip#audio_and_video_bitrates

On my fedora system i have to change -oac copy to -oac pcm and of course I still use my compiled mplayer and the -lavdopts fast:threads=2 option on the 3 lines.

Steps to get Mplayer working.
