I discovered that our company's old ASP code has not a memory leak, but a connection leak, and after 2 days of experimenting, I managed to get our sites to load in under 1.2 seconds by recycling app pools every 15 minutes. I taught myself how DFS works (distributed file share - an extension of AD technology, it maps a set of shortcuts on domain controllers and other DFS root holders), and expanded the available DFS roots to lead to a reduction in site load times. I hooked up an ultrasonic distance sensor and a motor shield to an arduino, and put the assembly on an RC car. I programmed it to slow down as it approaches walls, and to back up if something is too close. I want to build robots to fill some need, but I'm still looking for that need.
