Lightning talks at GTALUG Greater Toronto Area Linux User Group are being recorded on video. First time attending, I offered to talk for 5 minutes on Desktop Environments, followed by 5 minutes for questions. Others are technically deeper. Linux isn't my full time job, but I've spent the past 10 years of my life using it. (George Vari Engineering and Computing Centre, Ryerson University, Church Street, Toronto, Ontario) 20170711
