Restored some older posts

You can always use the Internet Archive to access older content, but there were a few key posts that people kept coming to my blog for.

Since they were useful documentation in their own right, and one of the things I like to do with this blog is missing documentation pieces, it seemed appropriate to restore and reformat them.

The restored articles are:

• Hiding arguments from ps
• The Proc Connector and Socket Filters
• Tracing on Linux

These all still appeared in the top 10 landing pages on the blog, even though the content has been missing for some time.

I decided not to resurrect any of the popular Upstart-related posts, even though they were intended as documentation, since one can now consider it deprecated and unmaintained.
