I've been following Rogert Ebert's column at the Chicago-Sun and I like his take on films. He recently gave his top 10 films of all time. I've seen 1. 2001: A Space Odyssey (Stanley Kubrick) 2. Apocalypse Now (Francis Coppola) 3. The Tree Of Life (Malick) 4. Citizen Kane (Welles) 5. Raging Bull (Scorsese) 6. Vertigo (Hitchcock) 7. La Dolce Vita (Fellini). I have not seen these: The General(Keaton), Aguirre Wrath of God(Herzog) and Tokyo Story(Ozu).

Even back in 1984, couples don't say let's go see The Terminator this weekend. It isn't a date movie. It's an action movie with Arnold Swarztnegger as a robot, excuse me, a cyborg in the lead role to prove it. It might also qualify as a nerd movie because it introduces the genre of post apocalypse, time travel and machine vs man in one movie. I am hooked by the lone volunteer hero going back in time to save mankind. Of course back in 1984 when the movie came out, the PC revolution is just taking off. I watched this movie again in the 90's and realized the premise is right on track. It wont be the computers of the defense establishment that's going to take over the world. People will own their own computer everywhere. People will connect them to everything. And well you know the story... Sarah Connor is the mother of the savior of the world, John Connor. Her son will take her last name because (shrugs) he doesn't know his father. She has a boring job ...

I have Ubuntu 11.10 and Arch in a dual boot setup. Most of the time I use Arch because it's faster and applications feels nimble. Gnome in Arch doesn't slow down after hours of use. The feel is light all around. But now and again there are bumps in the road. I usually have Banshee playing tunes while I work. I just upgraded to the 2.4 release yesterday. Songs suddenly halting randomly. Turns out it's my hard drives. So I went and use fsck on the partition. I did a $shutdown -rF now and enter. Arch failed on the automatic fsck and instead handed manual repair to the user, me. So I log to root and run fsck -f -p /dev/sdb3 to force check of the partition. It runs and returns a clean partition. The next time I boot Arch, it runs automatic fsck again and fails and hands manual repair to me again. I tried to skip it and reboot. Does it again. It only goes as far as udev and fails at mounting the filesystem. Some google solutions I tried are appending fastboot in grub and editing ...

Most people with laptops use their machines 3 hours continously. The limit is the battery and how efficient the hardware and their operating system use resources. For Desktop boxes plugged in to the electrical socket, this is not an issue. But my battery is not my topic today. I work with Ubuntu and Arch on my Desktop. It is natural for me to leave the computer on for 8 hours straight sometimes more than that. I do not encounter this in Arch and I have the Gnome environment on both. Now for the bug. Xorg. Xorg just uses too much memory. My top says it has 67-70% memory usage after 4 hours. The practical effects are sluggish mouse responses and slow graphics. After 6 hours of this, the whole thing is just unusable. Of course, I can just log out and log back in. Then it's fixed, until after 5 hours again. But this happens in Ubuntu and not in Arch.

A couple of months ago I suffered a bad superblock error in my hard drive. The hard drive in question made clicking sounds and refuses to boot. I ran some terminal checks and got the bad superblock error. I have multiple hard drive devices so I booted using the other devices by changing BIOS. But how do you repair a bad superblock? A superblock is a summary of data kept in your hard drive. Like a table of contents if I'm not mistaken. The ext4 file system in Linux keeps a backup of the superblock somewhere else in the hard drive. Check where that is - find the location. $sudo mke2fs -n /dev/device?/ where the device? is the hard drive you want to repair. It will output a group of numbers separated by commas. These are superblock locations. You must restore the backup. $sudo e2fsck -y -b output_number /dev/device?/ where the output_number is one of the group of number listed from the operation above. The device? is the hard drive you want to repair. The -y flag or swit...
