How to fix corrupt partition table

Have you ever seen 80 GB free space in 15 GB hard disk drive? I have just seen in my very old hard drive. I would like to install Ubuntu 5.10 into this drive. Unfortunately, the process always hangs during formatting. I also tried to use only first 15 GB with no luck. My thought is there might be something wrong in the partition table and I have to clear them all. Fortunately, Ubuntu comes with lots of hard disk utilities such as fdisk, cfdisk, sfdisk, parted, and hdparm.

First of all, I tried to see its cylinder, head, and sector recognized by BIOS and kernel. hdparm -i and hdparm -I shown that raw information and current information are different. Something wrong here. So I should make partition table with the correct information. parted and fdisk are not useful for this situation. Instead, I have to use cfdisk or sfdisk which allows me to override cylinder, head, and sector by the correct ones.

Ruby and BitTorrent

As of today, we know what BitTorrent is and how to use it. The original implementation of BitTorrent has been written in Python by Bram Cohen. From the BitTorrent, Python is now one of well-known language wider. Thanks! The original implementation then has been modified and extended to support more sophisticate features and some of them are so popular right now, e.g., ABC and BitTornado. Then Java, C, C++, and C# have been used to implement in different ways, e.g., Azureus, libbt, BitComet, uTorrent, and etc. Where is Ruby?

Comparison of ruby and python line by line (3/3)

This post is the last part of this comparison. I am going to demonstrate how to develop XML-RPC server and client in Ruby and Python. As I said earlier, I don’t know much about Ruby. Below ruby codes are based on an article in Linux Journal #144. I just tried to develop similar program in Python. There are 2 parts; server and client. Let me start from the server.
