$ rsync -av --include '*/' --include '*.mp3' --exclude '*' source/ target/

Will copy across only the files ending with .mp3 from source to target. On a similar note, following options to wget will download files ending with .mp3

$ wget -c -r -l1 --no-parent -A ".mp3" http://downloads.example.com/music/directory/

I wonder if I should move over my blog to Tumblr?

I think the comparison to bullshit is not not so apt, as bullshit has some intrinsic value as a fertilizer, and, where I currently live, as a fuel for heating homes.

On comparing the craze for Diamonds to Bullshit.

Sad to hear the news earlier today. Its quite rare to get the news of someone you know on the internet passing away. Kenneth had his own unique way of getting people to do interesting things. He was a part of several linux user's groups and participated actively in the foss activities around the country, given his age and health.

Anyone who has ever interacted with Kenneth "lawgon" Gonsalves over email, in a mailing list, on IRC or in-person at a conference is surely going to miss him and remember him well.

Haath Baalo'n Me Phere Tou Main So Jao'n Ga,
Koi Qissa Wo Sunaye Tou Main So Jao'n Ga,
Us Se Kehna K Mujhy Neend Nahi Aati,
Apni Banho'n Mein Sulaye Tou Main So Jao'n Ga,
Meri Palko'n Pe Sajey Hyn Kaii Raato'n Se Diye,
Koi Palko'n Se Bhujaye Tou Main So Jao'n Ga.
Aakhri Saans Mujhy Mauqa De De Ye Zra ,
Mera Wada Hy K Wo Aaye Tou Main So Jao'n Ga.
Baad Ki Baad Mein Dekhe'n Ge Us Se Kaho,
Aaj Ki Raat Na Jaye Tou Main So Jao'n Ga...

I spotted this on the comments page of Katherine Jenkins's live performance Requiem For a Soldier. Though it refers to English language, it applies equally to just about any country or civilization.

Nginx doesn't have mod_userdir like Apache, but the behavior can be emulated by the following configuration snippet.


# userdir simulation
location ~ /~([^/]+)($|/.*)$ {
  alias /home/$1/public_html$2;
  error_page 404 = @404;
  autoindex on;
}
location @404 {
  return 404;
}

Putting these location directives in a virtual host config section will let the virtual host publish user's public_html directories.

At times you may need to trace a ruby program's execution flow. Ruby's set_trace_func comes handy there.



When saved in a file called trace.rb and executed with $ ruby trace.rb, it outputs
