Firstly, I want to state that I am totally anti (dislike) Internet Explorer. There are several reasons that I don’t like Internet Explorer.

Internet Explorer version less than 9 has a lot of problems with CSS. As a result, as a developer, developing the webpages for among IE and other web browsers is exhaustive. In order to make the compatibilities, the CSS is almost web browser dependent. Besides that, CSS3 which is supported by most of the modern web browsers, does not work well in Internet Explorer. Luckily there is a trick using PIE. But this is not the best solution.

Recently, I found that Puppy Linux has a higher (visits of page) ranking than KNOPPIX in DistroWatch. Furthermore, Puppy Linux is also well-known for its old computer support. This is interesting.

Previously, I tried KNOPPIX, which I liked most is that it is able to save the user session. That means, if you installed any package or save the files in $HOME, reboot the KNOPPIX in the USB, those settings are still preserved. This is a feature which I didn’t found in other Live Media. I tried KNOPPIX because it is a distro targets on Live Media.

Recently, I was thinking about to use Puppy Linux with my old computer. Yet my computer is already installed with Arch Linux. I wish not to uninstall or replace the Arch Linux, because installing Arch Linux is time consuming and exhaustive.

Puppy Linux is a live media like KNOPPIX. The official website mentioned that it can be installed into the computer without affecting the original OS, that is, installed side-by-side. This makes me re-called side-by-side installation of Ubuntu and Linux Mint. I tried this feature before using Linux Mint installed in a computer with Windows. It works fine until I give up because of the upgrade problem.

I am using Arch Linux. Recently updated an old computer, the IBus from 1.4 to 1.5. As a result, there were two problems.

1. Cannot input anymore in any window, except Opera(?)
2. IBus Pinyin cannot change to “Full pinyin” mode, but only “Double pinyin” mode.

For the first problem, it doesn’t happen in my other computers. For the second problem, it happened in my other laptops.

To solve the first problem, I tried several ways. Deleting the “/.ibus”, “/.cache/ibus”, “~/.config/ibus”, and “.gconf/desktop/ibus”, none of them can reset IBus to the default setting (initial setting). I wanted to reset the configuration because I know that it should work well, because it does work well in my other computers. However, none of the directories is able to solve the problem, finally I chose to reset the GConf and dconf. (I personally think that dconf is the one storing the latest version’s setting).

I tried to escape from the Windows dependency problem. Wishing that all my devices can work without problem with Linux. But one of the greatest problems is that Canon PIXMA iP1600 does not have driver for Linux, except using iP2200 which is compatible.

Previously, I solved this problem with the virtualisation. This work perfectly to do my printing. However, it is still depending on Windows. Without Windows, the virtualisation is almost useless.

There are three ways of prayer according to Catechism of the Catholic Church.

1. Vocal prayer 口祷
2. Meditation 默想（运用思维、想像、情感、渴望）
3. Contemplation 心祷

What is the difference between meditation and contemplation? The following part is a summary from here.

Contemplative prayer is more passive or sublime experience of God. Meditative prayer is more from our work of seeking God (though with the aid from God). Contemplative prayer can be distinguished as the pure work from God.

I always thought that Wine (or WINE, WINE Is Not an Emulator) is good enough for me to play Windows games and running Windows applications without using the virtualisation such as VirtualBox. However, this is not completed.

Recently, due to a giveaway from CodeWeavers, I downloaded and tried the CrossOver. Then I found the comparison of Wine and CrossOver, CrossOver contains some proprietary components, which makes Windows applications run smoother than Wine. I tried, yes, there are some differences. But I am still using Wine because of my own favour.

This is an interesting thing. I love the tree so much. The Knowledge Tree here I mean is not referring to the Tree of Knowledge of Good and Bad.

Tree is a graph theory. The powerfulness of tree, is that almost any data structure can be represented into the tree. In order to store the data, we can use a single variable, for a single data. In order to store a list of data, we can use array and associative array (or hash, map, dictionary), list, vector, and others. Another powerful data structure which I like is the 2D array, especially used in matrix calculation. The 2D array represents the data in the table form. It is very useful in database. An image can also be treated as 2D array. Comparing the tree to the matrix, the tree is possible to represent the matrix (though it is not preferred).

Sometimes we use spreadsheet to store data as table just like database. Especially the features provided like sorting and filtering. This allows us to look at the data easily without the knowledge of SQL (structured query language). Furthermore, we can add in the rows easily, do calculation using formulae, and also copy-paste the data to any cell. Comparing to database, the data needs to be filled row by row, this is the main drawback. This is why spreadsheet is easier to use.

The best desktop environment I mentioned here, doesn’t mean the DE such as KDE, GNOME, Xfce, LXDE, etc. The purpose of this post is to express the best desktop environment, that is, the features and functionalities.

You can called me old fashion, does not able to follow the latest technology. Whatever it is, the followings are my opinions on the features:

Taskbar as in Windows XP, or task list as in Xfce.

The taskbar in Windows 7, which groups them all, not user friendly for me. At least two actions needed: mouse over (or click) to show the whole group, then click again into the window of interested. The best is ungrouped, zero level, all windows showed. The sorting can based on time or window name, at least the users will know how to find the window based on some rules. The DE like GNOME 3 or Unity are too bad for me. Group the windows or applications in workspace, difficult to switch between the windows.
