I found this cool script for renaming files using a Python script. Never thought it would be so easy.

import re, os
rxin = raw_input('enter a regex to search for:\n')
foo = re.compile(rxin)
newname = raw_input('enter a new base name:\n')
a = 0
for fname in os.listdir(os.getcwd()):
    allowed_name = re.compile(rxin).match
    if allowed_name(fname):
        # newfname = string.lower(re.sub(foo,
                                   # '', fname))
        # b = (newname + str(a))
        a += 1
        c = os.path.splitext(fname)
        b = (newname + str(a) + c[1])
        os.rename(fname, b)

Just started using svn

subversion logo

Today I started using subversion to update this website. After couple of initial hick ups things are working pretty fine now. If you are planning to use svn make sure to backup the blog before checking out.

Here is how I set up the blog to update using svn.

  1. In Terminal cd to the document root. (eg. cd /srv/www/htdocs/)
  2. mv <blog dir>/ <backup>/ -> If anything goes wrong, you could reinstate the blog by reversing the above.
  3. svn co http://svn.automattic.com/wordpress/trunk/ <blog dir>/ -> This will download a working copy of the latest WP bild.
  4. cp <path to wp-config.php from the backedup copy> <path to new blog root>/ (eg. cp backup/blog/wp-config.php blog/)
  5. cp <path to backed up copy of the uploads> <new wp-content dir> (eg. cp backup/blog/wp-content/uploads blog/wp-content/)
  6. cd <blog dir> and issue svn update command to upgrade the WP version.
  7. When you switch to the login mode, WP will automatically attempt to update the database. If there are any plugins or themes missing, you could install them now. (some plugins can be updated directly in the Admin mode)

Flawless (2007)

Just watched a British movie called Flawless. I must admit that it had created such a big excitement from the beginning to the end. There were hardly anything to complain about. The Music is great(I am a Jazz fan)! and Demi Moore plays her role pretty well too.

Storyline

“From director Michael Radford (THE MERCHANT OF VENICE, IL POSTINO) comes FLAWLESS, a clever diamond-heist thriller set in swinging 1960s London. Demi Moore plays Laura Quinn, a bright, driven and beautiful executive at the London Diamond Corporation who finds herself frustrated by a glass ceiling after years of faithful employment, as man after man is promoted ahead of her despite her greater experience. Michael Caine is Hobbs, the nighttime janitor at London Diamond who is virtually invisible to the executives that work there, but over the years has amassed a startling amount of knowledge about how the company runs. Hobbs has his own bone to pick with London Diamond. Observing Laura’s frustration, he convinces her to help him execute an ingenious plan to steal a hefty sum in diamonds. But unbeknownst to Laura, Hobbs plans go even farther than he’s let on, and together they set in motion a thrilling heist of dizzying proportions, the likes of which London has never seen.”

finiteloops.com finally complete

After months of testing various CMSs, I have decided to install WordPress on finiteloops.com. This wasn’t an easy task as it was difficult to find a easily configurable CMS with good themes and plugins. So far I have tried Textpattern, Movable Type, e107, Drupal, and couple of more. Every single one of them have their strengths and weaknesses but overall WP gave me the best impression.
