This week I taught a couple of classes to the new missionaries who have joined our mission board. In my notes I highlighted several tools. Here are the tools I talked about, they range from creating back ups to VPN to malware. If there is a MissionaryGeek article on the topic, I will link to it for further information. Otherwise you can use this list to do further research on your own.
While there are many good choices in most of these categories, I have tried to limit the list to just a few so that it is not too overwhelming. Please let me know in the comments if there is a significantly better tool that I can recommend.
