Console progress bar

It's very simple:

import sys
def update_progress(iteration, total):
    percent = int(iteration * 100.0 / total)
    sys.stdout.write(
        "\r[ {0:<51} ] {1}% ~{2}".format(
            '#' * (percent / 2), percent, iteration
        )
   )

The main trick is character "\r", which clear previous line.

Linux installation

2 years using OSX gave me more insight on how Unix system work more than before. This time for new home's desktop, I decided to use a Linux.

I chosen Debian testing with XFCE

 http://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/debian-testing-amd64-xfce-CD-1.iso 

Why testing? It has latest piece of software. Seems to unstable but it works. There is a good alternative are Mint, elementaryOS, good-looking but buggy, and security faults are largely ignored www.techrepublic.com/article/why-the-linux-mint-hack-is-an-indicator-of-a-larger-problem/

XFCE gives many customization chance and very, very fast! Resources usage is also optimized.



Default fonts is unpleasant, especially for Japanese text. To have above result, there is a fix for it by setting fallback chain in /etc/fonts/local.conf

Here I used Tahoma from Windows and Monaco from OSX, but Open Sans and Ubuntu Mono are good alternatives. Takao font is an IPA font derivatives, installed by apt-get install fonts-takao*

Font Osaka causing ugly rendering on many latin characters, better to remove it
sudo rm /usr/share/fonts/truetype/Osaka* -f

It's easy to set system wide shortcuts. There are 2 places:
* Window manager: pre-defined functions
* Keyboard setting: a function is a command

About input methods, there is "uim", better than D-bus and Scim etc I have used.

For Japanese I use Mozc. It's important to set "Default input mode" to Hiragana to make it work as expected.

For Vietnamese I use m17nlib. Add "m17n-vi-telex" to Enabled input methods. It just works.

apt-get install  uim-mozc uim-m17nlib uim-gtk2.0 uim-gtk3

Hope that using it daily can boost Linux skill :D
