...D, before the system is even booted the first time. -- Clifton -- Clifton Royston -- cliftonr@tikitechnologies.com Tiki Technologies Lead Programmer/Software Architect "My own personal theory is that this is the very dawn of the world. We're hardly more than an eyeblink away from the fall of Troy, and scarcely an interglaciation removed from the Altamira cave painters. We live in extremely interesting ancient times. I like this idea. It encourages us to be earnest and ingenious and brave, as befits ancestral peoples; but keeps us from deciding that because we do...

...: The <K produces a vector of logical TRUE's for all cumsum values <K. This is silently treated as numeric 1's when added by sum(). A moment's thought will make clear why 1 must be added at the end.. Sure enough, this vectorization reduced the time about another twofold -- to an eyeblink -- for my modest nsim sizes. Approach 4: The last stage, of course, is to get rid of the outer loop, which fills the vector for the distribution one element at a time, again another R no-no. One way to do this -- the ONLY way I could think of (so a challenge to smarter R programmers) -- is to mak...

The following runs in an eyeblink on my 700Mhz Thinkpad T-20 (256 MB RAM) with Windows NT: var(matrix(rnorm(4000000),ncol=4,nrow=1000000)) This also has the virtue of being quite readable. You could allow an arbitrary covariance matrix and mean vector and it increases the time slightly, but still only about 5 seconds. Regarding...

...you might imagine, this makes the app run very slowly. This happens with one user or with many. The ?mbd processes aren't raising a sweat, a few % of CPU at most. Samba delivers (and accepts) data at up 9.8MB/s sustained to smbclient over a 100Mb/s link, and delivers 2MB images to XP in an eyeblink, so it's not a fundamental networking failure. There is no perceptible speed difference serving from a muscly hardware-RAIDed-SCSI dual-CPU gig-of-RAM server or my el-crappo AOpen laptop. This DID NOT HAPPEN with their old Novell file server using Novell's networking protocols. The app...
