PPT-Xrootd usage @ LHC An up-to-

date technical survey about xrootdbased storage solutions Outline Intro Main use cases in the storage arena Generic Pure xrootd LHC The AtlasSLAC way The Alice way CASTOR2 Roadmap Conclusions. Nate Birkholz, Jessica . Standley. and Bo Xiao. MYTH. : Taxing grocery bags or banning plastic bags will reduce greenhouse gasses and save the planet.. TRUTH. : Since bags are a minimal contributor to all the problems associated with them (oil use, litter, landfill volume, etc.), bans and taxes simply won't do anything for the environment. And because the alternatives all require more fuel to create, recycle, and transport, eliminating plastic bags actually increases greenhouse gasses.  .
