Years and years ago at university, I was an engineering student taking classes I was not completely comfortable with. I did not mind the math, science, and engineering classes but had difficulty with ones classified as humanities or language. This…
If you work in the computer industry long enough, you realize that certain things are done more from tradition than from keeping things simple. Recently I helped one of my wife’s friends install an ADSL Broadband Internet connection. In theory…
One of the most confusing things ever invented is time zones. Well, they aren’t inherently confusing by themselves but when you start talking about different time zones and daylight savings, then things get messy. Add in a factor of government…

Scientists say that many different realities exist. It is impossible to prove this however. If one path is chosen, how is it known another path concurrently exists? How can a length of string know about other strings? Only from a…
Back in 1996, not long after our first release of WinFrame, Citrix received some feedback that there was a need for more security. Specifically, it was considered dangerous to specify any executable from the client side to be run on…
