Digital Media Minute has posted about free mind map software before, but I have to say, for elegance and ease of use, Mind Node is unbelievable. I’m actually looking for reasons to use it! I’ve found the freeware version to be very adequate for my needs so far. Mac only, unfortunately. Again, even if you think your current methods of staying organized, planning out projects, or even planning a party for the weekend are sufficient, do take a look at MindNode and I’m betting that you will go to the trouble of installing it.
I’ll spare you the details of my epic sock drawer rearrangement plan, and offer you this video instead:
Network Discovery Tool
If you need a network discovery tool for information on your network about IP addresses, hosts (and a whole lot more) but command-line tools intimidate you, take a look at this Zenmap tutorial. It works together with Nmap, the free, crossplatform network discovery tool. I think I’ve run across tools that I can use to get this done before but I don’t remember any of them being quite this simple to implement. In any case I have had Zenmap recommended to me before so this tutorial is definitely going into my “you want to look at this later” bookmark folder. Take a look.
