Sometimes I have text files containing simple one line records that are used on more than one computer so they may get out of sync. For example, password files maintained on more than one machine, user records or the like.
"Free and Open Source Software" (FOSS) is behind the Internet revolution. Without FOSS, if it existed at all, the Internet would be very different and much smaller. It started with the protocols and basic applications but FOSS is no longer niche or the domain of geeks. Apache serves up most of the worlds web sites. MySQL provides the database to power many of the worlds websites and increasingly Firefox is being used by everyone to browse web sites.
I often get engrossed in work and forget things like picking the kids up from the bus stop.

By the time I've made time to do that I've often forgotten what I'm supposed to be reminding myself about.
