No more Fedora Core?

January 6, 2007

I ran across this RSS title from digg.com this morning. Feeling sad for FC, which is my first Linux distribution. I was attracted by the blue-style of FC before touching Linux. However, a close look into the article seems this a “joke”, here is the link.

Starting with Fedora 7, there is no more Core, and no more Extras; there is only Fedora. One single repository, built in the community on open source tools, assembled into whatever spins the Fedora community desires.

Is this a word game just like rename “Fedora Core” into “Fedora”? At least, it seems nothing differnt to me. I think there is one thing for sure, there is no more the name of “Fedora Core”, not Fedora Core.

Tomboy icon on the KDE tray, finally

January 5, 2007

Tomboy is a nice note taking application that I am using it everyday. But it is really annoying that no icon is there on the KDE tray. But it is really there, like a transparent icon. These problem seems a bug in the 0.4 release, because I saw someone else got the same question in some forums. But now with the 0.5.1 release, the tomboy icon finally can be displayed on the KDE tray. Of course there are other new features, please check here.

Superswitcher — A nice Alt+Tab alternative

January 5, 2007

Today I came across a nice small application called “Superswitcher” from LinuxTOY. It is quite handy to use Win+direction keys to switch from desktops and applications in one desktop.

“SuperSwitcher is a (more feature-ful) replacement for the Alt-Tab window
switching behavior and Ctrl-Alt-Left/Right/Up/Down workspace switching behavior
that is currently provided by Metacity.”

Don’t worry about the homepage of Superswitcher is inside the Gnomefile, because I found it works perfectly in my KDE desktop environment. It also has some other features like move windows, find particular windows by key combinations. The only problem I found so far (after trying 2 min only…) is that it conflicts with my KDE shortcut. I have Win+ KEY to open applications, and Win+Ctrl+KEY to switch to that window. Now I can’t use them if I have Superswitcher on. I’ll try to find a way to overcome this…

HOWTO: backup my Ubuntu

January 1, 2007

This is a short guide to my backup scheme. I use this nice guide from the ubuntu forum. First of all, I found it will take ages to extract some certain file from the huge tar file of the whole system backup. So I backup separately. The idea is to backup the home folder into 3 files, and other system files into one. Here they are:

  • tar cvpzf /media/SEA_DISK/Backup/Linux/Wei/personal_111206.tgz /home/wei/personal This backup all the personal files include my pictures and application files (say KmyMoney file).
  • tar cvpzf /media/SEA_DISK/Backup/Linux/Wei/samba_111206.tgz /home/wei/samba
    This backup the samba folder, which is used to share with my Windows XP via VMWARE. Yeah, I am still usingWindows XP, unber VMWARE. I have to use windows to do some study. This folder is shared between Ubuntu and Windows XP so that I can save the data file in Windows and edit my paper in Ubuntu with just “Ctrl+Alt” to switch out VMWARE.
  • tar cvpzf /media/SEA_DISK/Backup/Linux/Wei/wei_others_111206.tgz –exclude=/home/wei/personal –exclude=/home/wei/samba –exclude=/home/wei/songs –exclude=/home/wei/vmware /home/wei
    This backup all the other files in my home folder except the”song” folder, which stores temporary mp3 files I copy from my external hard disk occasionally.
  • tar cvpzf /media/SEA_DISK/Backup/Linux/system/system_edgy_kde_111206.tgz –exclude=/proc –exclude=/lost+found –exclude=/mnt –exclude=/media –exclude=/home / This backup all other system files.
  • One very IMPORTANT hint: don’t add the last “/” symbol in the exclude parameter. For example, write “–exclude=/home”, but NOT “–exclude=/home/”. Maybe this is a tar bug. /media/SEA_DISK/ is the mount folder of my external hard disk. 

Just these simple steps to backup my Ubuntu, with no need to boot by a CD using Ghost. This is done in running Ubuntu. Amazing, isn’t it? I haven’t restored my Ubuntu yet, but it is just unpack this tar files, again, in the running Ubuntu. In fact, I doubt there wouldn’t be a chance that I have to restore it, Ubuntu seems so stable and easy-repair.


Update Opera using non-free repository

December 31, 2006

Opera has updated to 9.10. I can’t remember how I installed opera, but I can’t update it using “sudo apt-get dist-upgrade”. This post has exactly the same problem as mine. So, I changed my old stable repository into this “#deb http://deb.opera.com/opera/ etch non-free”, and use this in the terminal to add public key:

 

sudo gpg –keyserver subkeys.pgp.net –recv-key 6A423791
sudo gpg –fingerprint 6A423791
sudo gpg –armor –export 6A423791| sudo apt-key add –

 

and then “sudo apt-get update”, “sudo apt-get dist-upgrade”.


HOWTO: Canon PIXMA IP1500

December 31, 2006

I have a Canon PIXMA ip1500 printer which I usually print in the Windows environment. I came across a software called Turboprint one day. My printer model is supported. I downloaded it and installed. Everything seemed perfect (except the GTK1 interface). But it turned out that every paper I print has its logo on, even I try the lowest resolution. And I have to pay $34 to register to use it with full function. It seems ridiculous that I have to pay almost equvalent money as my printer to drive it in my Linux! Uninstall it immediately…

I searched Ubuntu Forum with “ip1500” , there are lots of posts. I read some of them, looked quite complex… so I didn’t try then. But today I am quite free so I decided to drive my ip1500 in my Ubuntu. Fortunately, the first post I read from my search result is a perfect one. Here it is. I’ll just add a link where the official driver for Linux can be downloaded.

As the post said, despite the official site said the OS is SUSE, it works perfect on my Ubuntu Edgy with KDE. Just install the printer from KDE control center instead of “gnome-cups-manager”.


Make Opera not use the KDE color scheme

December 29, 2006

After I installed KDE desktop environment in Ubuntu and changed a dark color scheme, my opera brower uses this color scheme automatically! People discuss around how to make Opera using the current KDE theme, but no one wants to leave Opera alone. The reason why I want to do this, or must do this is because some website seems to set font color to be dark or black. As in my KDE color scheme all the background are black, and the foreground is white (I like this high contrast), I can’t see much in this color scheme. See the screenshot:

Opera in KDE color scheme(KDE color scheme) Opera in default color scheme(Default color scheme)

I searched around and found no answer in opera community, kde, ubuntu, kubuntu forums… Then I played around all the opera settings, nothing to configure this. Then I found there is one file that is the key to this problem. That is “~/.qt/qtrc“. It seems opera will read the color scheme from this file every time it launches. I found this because when I launch opear as root, the color scheme would become default, same as the root color scheme. Then I make my hotkey “Win+O” to run this command “mv ~/.qt/qtrc ~/.qt/qtrcc & opera“. By doing so, this qtrc is renamed as qtrcc, Opera will use the default color scheme if this qtrc file is not found in the ~/.qt folder. I’ve been doing this for weeks, nothing bad happened to any of my other KDE programs. So I guess this will resolve this problem before I found an “official” way. By the way, this qtrc file will be created every time I logged in Xwindows, I rename it to qtrcc just in case some day somehow this file is not created.
