Does this remind anyone else of the Emo Philips Northern Conservative Baptist Great Lakes Region Council of 1912 joke?

Using strace and lsof

Using strace and lsof to debug blocked processes

You can use strace on a specific pid to figure out what a specific process is doing, e.g.:

strace -fp <pid>

You might see something like:

select(9, [3 5 8], [], [], {0, 999999}) = 0 (Timeout)

Condensed iOS Human Interface Guidelines, formulated as imperatives.

Condensed iOS Human Interface Guidelines

Imperatives for AppStore approval

For iPhone app developers. Emphasis on getting the fastest app store approval. Everything stated as suggestion made into an imperative. When "violating" these imperatives, you can check for yourself what the caveats are. Generally speaking, deviating will more likely cause your app to be hung up in approval.

You can read this entire document in about 20 minutes. This is faster than reading and understanding the entire Human Interface Guidelines.

an HTML VIM movement cheatsheet for use with NerdTool
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

This is an HTML version of a great [VIM movements cheatsheet][] designed by Ted Naleid.
I made this because I wanted more control over the way the text was displayed, and I'd rather tweak CSS than mess with Omnigraffle. If you just want Ted's graphic overlaid on your desktop, you should download the [transparent version] of the VIM movements cheatsheet.
I use it with [NerdTool][]. Sadly, NerdTool can't overlay transparent HTML. So I supply a background-image URL. You'll want to change that to something on your local filesystem. Here is a [screenshot][] of the results. The background image is taken from the always great [Bibliodyssey][], resized to the size of my screen.
