Hi, I am using the Random Forest Package, and want to do an automatic rerun using only those variables that were most important in the original run. Is there anybody who has experience with this and can give me helpful suggestions?

Hi. I experimented a bit with collecting entropy from the time it takes for device_attach() to run (in CPU cycles). It seems that those times have enough variation that we can use it for entropy harvesting. It happens even before root is mounted, so pretty early. On the machine I'm testing it, which has minimal kernel plus NIC driver I see 75 device_attach() calls. I'm being very careful
