Writing in Korean

Install ibus, ibus-m17n, ibus-hangul

Restart - I couldn't use ibus in Chrome or choose the Romaji keyboard option until restarting

Ctrl-Space to activate language. Change keyboard to Romaji for English keyboard.

Scim also has a Korean package but I couldn't get it to activate reliably.

Set linux date

Use this graphical tool to set the timezone:

sudo dpkg-reconfigure tzdata

Or set the time directly with:

sudo date MMDDhhmmYYYY

Left hand mouse

One of the buttons on my laptop broke so to avoid that key I switched to using a left hand mouse:

xmodmap -pp
There are 12 pointer buttons defined:

    Physical        Button

     Button          Code

        1              1

        2              2

        3              3

        4              4

        5              5

        6              6

        7              7

        8              8

        9              9

       10             10

       11             11

       12             12

 xmodmap -e "pointer = 3 2 1 4 5 6 7 8 9 11 12 13"

chrome user agent

Chrome doesn't seem to currently have a setting or extension to set the user-agent.

You can however define it with a command line argument:

  chromium-browser --user-agent="richard"

Working with large CSV files

When working with large CSV files I sometimes get this:

Traceback (most recent call last):
  File "stats.py", line 12, in
    for i, row in enumerate(csv.reader(open(filename))):
_csv.Error: field larger than field limit (131072)

This means the CSV file contains more content between delimiters that allowed by default. To raise this limit use:

import sys
import csv
csv.field_size_limit(sys.maxint)

Change keyboards

Change keyboard to DVORAK:

setxkbmap dvorak

And back to QWERTY again:

setxkbmap us

My vimrc

set encoding=utf8

set textwidth=0
set tabstop=4       " Number of spaces to expand tab (messy)
set softtabstop=4   " Number of spaces for insert for tab

set expandtab
