Bit Rot Amnesia

By Mike Deliman Spirit Rover has been having a number of problems recently, anomalous behaviors, losing contact with Earth, even forgetting commands.  Amnesia has been one of the larger concerns.At the heart of this issue is a bank of flash memory.  Flash pretty much works by saturating cells to "1"s, then writing the cells that need to be 0's.  "quantum wells"…

By Mike DelimanThis morning we've made a couple of announcements that will hopefully surprise and delight the Real Time computing community.  Wind River is releasing two new products that have their base in  virtualization: Wind River's Hypervisor, and Wind River's MILS 2.0.  Both of these products introduce platform virtualization, used in different ways.   Wind River's implementations allow for a…

Tolerating Delays

By Mike DelimanThis may sound a bit funny, but in the space industry, we're constantly playing catch-up.  We're either looking at or for things that happened millions or hundreds of millions of years ago, sending rockets off to get to where something will have been just in time to take a picture of or bore a hole into it, or…
