Your local library isn't just a place you go to find a new novel without paying for it. Libraries subscribe to a number of different business directories, which makes them a perfect place to get leads for free —especially for B2B salespeople. These directories aren't limited to resources like Internet reverse lookups, although such a tool can be very useful if you're looking for business leads. Many companies make it their business to organize information about both the company and their consumers. This information is compiled into a huge database, and this database is pure gold for any salesperson looking to create a new lead list.

In 2006, OpenBSD started the first campaign against the use of binary blobs in kernels. Blobs are usually freely distributable device drivers for hardware from vendors that do not reveal driver source code to users or developers. This restricts the users' freedom effectively to modify the software and distribute modified versions. Also, since the blobs are undocumented and may have bugs, they pose a security risk to any operating system whose kernel includes them. The proclaimed aim of the campaign against blobs is to collect hardware documentation that allows developers to write free software drivers for that hardware, ultimately enabling all free operating systems to become or remain blob-free.
