CSS menus
August 31, 2010 - 11:09pm
For the longest time I had been battling css menus with floating LIs. If the LI has within it normal text, instead of an image, each browser will indefinitely display the LI's with different widths because each font will be displayed differently. I either ended up usually giving fixed widths to each of the LIs, (which sort of defeated the purpose), or ended up with the entire menu being short of...
Learning Javascript Through Negative Example
June 24, 2010 - 11:09am
The last couple weeks I've spent learning a client-side Javascript application framework, sproutcore. In the process, I took the opportunity to take a refresher on my javascript skills.
A decade and a half after the emergence of Javascript, there is still a tremendous amount of confusion, even among developers, between Javascript (an awesome scripting language that is built into web browsers)...
Read notes as html
June 17, 2010 - 3:04pm
I tend to keep a lot of notes around my ~/docs directory. They are
formatted in Pandoc Markdown
because it's easy to type and easy to read. However, sometimes the
notes get fairly extensive, and it's nice to be able to read them as
html in a web browser rather than in the terminal window. To that end,
I wrote up this little tool that I call vah -- "View As HTML". All
it does is orchestrate the...
SMS to Web
June 10, 2010 - 10:10am
I set out to find just some basic information about how text messages translate into website actions, and ended up with more information than expected. SMS is the term for short messages service, referring to a message being up to 160 characters, and being sent from a mobile phone, or (SME) to a short messages service center, (SMSC), stored, and then forwarded to another SME.

Filter a directory listing by characters
November 6, 2008 - 11:32am
In Bash, you can get a list of files filtered by a range or choice of characters in the filename by using character expansion. For example, to get a listing of just log files in /var/log ending in .1, .2, .3 and .4, use this command:
$cd /var/log
$ls -l *.[1-4]
Or to just see the files ending in .1 and .4, use:
$ls -l *.{1,4}

show all process information with ps
July 16, 2008 - 1:10pm
$ps axww
The a option displays all process information other than your own.
The x option displays process information for those with no terminal; in other words, daemons and such.
The ww option tells ps to display all process information regardless of the window size. Info will be wrapped to the next line and not cut off like normal.
Ps is useful for getting information about what and how...

How to find listening tcp processes
July 10, 2008 - 9:36am
Sometimes you need to know what services are listening to what ports on your unix box. Two utilities that can get you some of this port and process information are netstat and lsof.
With netstat, you can find out which services are listening under which ports:
# netstat -na
The n option prevents ip to hostname lookups.
The a option adds to the output the sockets used by server processes.
