what want simple. if datetimeoffset of created event older 24 hours want removed database. having huge amount trouble working converting system.linq.iqueryable system.datetime . any appreciated. index of events public actionresult index() { iqueryable<datetimeoffset> b = db.events.select(x => x.eventtime); datetimeoffset currentdate = datetimeoffset.now; if (currentdate > b) { db.events.remove(@event); db.savechanges(); return view(db.events.tolist()); } return view(db.events.tolist()); } my other question how structure requires 24 hour difference in order remove row database. the data table has eventtime datetimeoffset data type. i have been trying use datetimeoffset.compare(currentdate, b); but visual studio isn't liking line well. please if know how compare time database current time. there nothing in regards on site. have spent day on site , have yet find along this. thanks it might ea

background: i'm trying integrate new sensor android platform. development purposes, using nvidia jetson-tk1 dev board , spark core. spark core communicates sensor , outputs data serially through usb. at high level, needs are: to able read/write serial data spark core on usb to handle data android service written api accomplish @ high speeds in future when become more experienced @ working hal, may eliminate spark core , use gpio pins on jetson control sensor ic. onto details: i can read data through command cat /dev/ttyacm0 , i'm looking more low-level approach. want use hal communicate device. specifically, want spark core show when cat /proc/bus/input/devices . want able read data using getevent /dev/input/eventxx . the main question: here approach: find or develop usb device driver in native c code use jni compile driver within android source code create hal module (.so binary) hal definition compile android source code kernel
