collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD files.

daemontools is a collection of tools for managing UNIX services

logstash is a tool for managing events and logs. You can use it to collect logs, parse them, and store them for later use (like, for searching). Speaking of searching, logstash comes with a web interface for searching and drilling into all of your logs.

The hype around social media over the last few years has pushed people, and organsations into the adoption of tools they don’t fully understand in order to keep up with competitors or industry leaders. This has led to many failed social media initiatives. No one argues that social media tools aren’t a great way to get the word out about all aspects of your work and social life. Depending on whether you are a private or public company, a government organsaition or just an individual with thoughts you want to share, social media can help you reach your audience.Why is it then that so many organisations are failing with social media?

The number one reason in my opinion, is lack of preparation. Organisations don’t research the medium correctly before jumping in. Researching social media is a matter of “listening”. Organisations simply don't take the time to listen. Listening is the first step in any social media policy and if you skip the first step your initiatives are doomed.
