Shortlinks, like bit.ly and others, seem to be everywhere in today’s social networks and looking at Twitter or the way some websites are built, or if you just need a short and easy to remember link they do have their uses.

The Importance of Being Earnest … – about virtual education
… about virtual education.
When I was still in school my world was restricted to my immediate friends and surroundings. If I wanted to visited relatives or friends living farther away it took quite some time. With the arrival of modems and BBSes my small world became a little bit bigger. And when the World Wide Web and eMail established themselves and virtual worlds began to emerge in the mid nineties my world expanded to include everybody who had access to an internet account. Nowadays the number of people who have access to the internet in some form or the other has multiplied x-fold, and our world is expanding, or maybe I should say our perspective is expanding, the world itsself seems to have become smaller.

On the local side basically all average grid owners can do, is to take basic measures like a firewall and ensuring their system is up to date. It would be advisable though to go a step beyond the usual and use programs like portsentry or fail2ban to thwart and block the casual hacker. If you really have a determined and knowledgable hacker there is not really much you can do to keep him or her out.
