Ever wondered where all that disk space has gone? Why the 100GB drive is not 100GB?
Well apart from some systems using GiB and others GB and then some manufacturers using base10 and not base3 and saying that 1GB is 1000MB and not 1024 – I have found another one.

Beijing Software Freedom Day: A fire breathing Dragon of a success!
Published by September 16th, 2007 in China and FOSS/GNU/Linux. 4 CommentsWell, we came, we championed, we explained, we lobbied and we taught. We laughed, we gathered, we swapped tales and we helped clear up some misconceptions.
