john alvero's personal blog: May 2010

First, why should you upgrade or change your kernel? Here are just some of the reasons:

You need a feature that only the newer kernel supports
You came across a bug which is fixed in the newer version
You have a device driver that needs kernel recompile either as a module or compiled with the kernel
You are bored

As for me, I got bored.

Overview of the process:

Update apt sources
Install the necessary pre-requisites
Get the kernel source
Compile
Install the kernel and modules
Reboot with the new kernel

Here are are the steps:

1. Update your APT sources

apt-get update

2. In Ubuntu 10.04, /bin/sh is linked to /bin/dash. This may be a problem during compilation. Change the link from /bin/dash to /bin/bash

rm -f /bin/sh
ln -s /bin/bash /bin/sh

3. Install pre-requisites

apt-get install kernel-package libncurses5-dev fakeroot wget bzip2

4.Get the kernel source

cd /usr/src/
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.34.tar.bz2
tar xjf linux-2.6.34.tar.bz2
ln -s linux-2.6.34 linux
cd linux

5. Copy the config of the running kernel as a basis configuration for the new kernel. It's usually a good idea to do this.

cp /boot/config-`uname -r` ./.config

6. Now we are ready to select kernel options. This is also the time to select weather you want a driver compiled as module, with the kernel or not to include at all. You have to options in doing this -- using a nice GTK menu or using the console (curses based). The latter is usually the way to go but if you want the former make sure you install libgtk2.0-dev and libglade2-dev first. For now, we will go with the console (curses)

make menuconfig

make gconfig

This will bring up the kernel configuration menu. Go to "Load Alternate Configuration File" and choose ".config" as the configuration file. This will load the configuration for the currently running kernel. Browse through the options and make your changes. When you are finished select "Exit" and choose YES to save.

7. We are now ready to compile the kernel. This process will take a considerable amount of time depending on the speed of your machine and the number of modules you choose to compile.

make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=-custom kernel_image kernel_headers

You can substitute anything for --append-to-version paramater as long as it starts with a "-". This string may be your version or revision number or simply just a tag.

8. When compilation is done, we can now install the new kernel and modules

cd /usr/src/

root@john-desktop:/usr/src# ls -la
total 106128
drwxrwsr-x  5 root src      4096 2010-05-18 14:50 .

-rw-r--r--  1 root src  34340580 2010-05-18 14:47 linux-image-2.6.34-custom_2.6.34-custom-10.00.Custom_i386.deb

dpkg -i linux-image-2.6.34-custom_2.6.34-custom-10.00.Custom_i386.deb
dpkg -i linux-headers-2.6.34-custom_2.6.34-custom-10.00.Custom_i386.deb

9. Reboot. Enjoy!

While the 2010 Election was generally peaceful and the results came in fast, it doesn't mean the results were correct. I am referring to:

http://electionresults.ibanangayon.ph/res_reg5808114.html

http://electionresults.ibanangayon.ph/res_reg5808113.html

http://electionresults.ibanangayon.ph/res_reg5808112.html

http://electionresults.ibanangayon.ph/res_reg5808111.html

http://electionresults.ibanangayon.ph/res_reg5808110.html

These results are impossible and could not possibly happen. This is just for 5 clustered precincts. The effect of this mistake for a hundred CP is unimaginable lest a thousand. So i whipped out a small script to find other precincts where results are "questionable". The script basically checks for the "percentage" of votes garnered for a particular candidate. If it goes beyond the pre-configured threshold, it flags the file and makes a log.

Also, you need a local mirror of http://electionresults.ibanangayon.ph which can be easily accomplished with:

wget --mirror –w 2 –-convert-links http://electionresults.ibanangayon.ph

If you are on PLDT, use http://124.105.166.195/, for GlobeTelecom, use http://222.127.18.105/

Remember to edit $SearchFor, $mirror and $threshold to suit for needs.

UPDATE: (May 17, 2010)

I ran the script on my local mirror and here is what I found. (note that my local is not complete yet and scanning is not yet over)
