How to mirror a static copy of the opensource.org website

I currently maintain the italian mirror of the Open Source Initiative web site, and today I realized that the script I wrote some months ago wasn’t doing its job well.. because the CSS files weren’t downloaded at all, causing a rather unpleasant rendering of the site.

To mirror opensource org I’m currently using the plain’ol GNU Wget -r—mirror and so on. While the good’ol wget downloads each page prerequisite defined in the HTML source, it doesn’t support @import CSS rules, and doesn’t download images referenced in CSS with url() rules.

BTW, nothing that can’t be resolved with some regex-fu: that’s why I’m sharing the script I’m currently using to mirror the opensource.org web site, hoping it will generate either a new mirror or some insights on how to do this job better :).

The script: update_opensource_mirror.sh

Enjoy! :)

What does your .bash_history say?

A friend of mine told me that on techie blogs there is a new meme going on: show off the most used commands, starting from shell history:


history | \
 awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | \
 sort -rn| head -15

I’ve got 20 times the default bash history size (10k lines), so it’ll yield interesting results. I also use the history timestamp feature, so I’ve added a little sed to the code in order to strip timestamps out.

Let’s see:


 13:19:50 vjt@voyager:~/code*$* history | 
     sed 's#^[ 0-9\[\/\:]*\]\([^ ]*\).*#\1#' |  
     awk '{a[$1]++}END{for(i in a){print a[i] " " i}}' | 
     sort -rn | head -15
928 l
577 ssh
389 ping
381 cd
300 dig
259 telnet
153 sudo
126 ifconfig
125 whois
113 ps
96 svn
91 cat
73 fg
68 vi
61 ..

yeah, I do a LOT of ls, l is actually ls -alFGs (I’m on Darwin). This list exposes my recent habits, because I’m coding less and managing more (no gcc, no irb, lots of dig & whois). svn is still there, of course ;). ssh means that these results should be aggregated with other histories coming from the other boxes I log on to.. but that’s a topic for anoter post ;).

Which are your results?

Post them here! :D

UPDATE 2008-06-03

As my recent habits are more coding than writing docs, I re-ran the history analysis.. and these are the new results:
