A quick Unix tip I thought I should share. If you need to get an approximation of how many files are in a directory and its subdirectories, the du command is a great help. By default, to use the du command you would type something like this:
du .
This command lists all the subdirectories of the current directory and their size in 512 byte blocks.
The following is a more useful version of the command.
du -ak .
That command lists all the subdirectories and files in the current directory and lists their size in kilobytes. This command can be very useful when used with grep to do quick searches.
Finally, if I want to get a line count, I add the following:
du -ak . | wc -l
The wc -l command counts the number of lines in the output of the du command. Since there is one line per directory and file its not an exact file count, but it can be real useful for quick comparisons and the like.
Hyper-Threading Technology3 (two threads) provides high performance-per-watt efficiency in an in-order pipeline and increased system responsiveness in multi-tasking environments. One execution core is seen as two logical processors, and parallel threads are executed on a single core with shared resources.
I found this story on Giga OM that points to this story on making web sites faster. A tool for FireBug called YSlow is covered in the story. Looks interesting, it is not something I have used, but I intend to give it a try.
I ran across this when searching for a VNC client for the Mac. It turns out OS X has one built in. To use it do the following:
