Hi, I'm trying to calculate some functions loop, unfortunately my data are decimal numbers that not allow me to get an accurate estimate. I do not want to use neither "round "nor "signif" but I would prefer to have all the information available, (the function loop is generic so you should adapt to all data, not just those in particular). The approximation error is

Dear Rusers, I have used R,S-PLUS and SAS to analyze the sample data "bacteria" in MASS package. Their results are listed below. I have three questions, anybody can give me possible answers? Q1:From the results, we see that R get 'NAs'for AIC,BIC and logLik, while S-PLUS8.0 gave the exact values for them. Why? I had thought that R should give the same results as SPLUS here.

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 performance, having tons of RAM is crucial. My Windows NT and the

I made a list of /usr/bin scripts which allows /tmp races. Following ones creates /tmp/something.$$, then, with no permission/ownership checking, /tmp/something.$$.x (x may vary ;), or even performs suitable checks, but gives enough time to alter /tmp contents: glibcbug, bashbug, znew, mailstat, autoupdate, x11perfcomp, gccmakedep, pnmindex, xcopy, autoheader, cvsbug, rcs2log, updatedb, igawk,

The problem with vixie cron is wider (and more funny) than I expected. Here''s my proggy which allows hiding files of any kind and size into crontab entries (remember, quota is ignored ;-): -- cron_put -- #!/bin/bash echo "Vixie cron 3.0.1 file storage - put utlility" echo "by Michal Zalewski <lcamtuf@staszic.waw.pl>" echo if [ "$1" = "" ];

Typical "[symbolic|hard] link bug" is a vunerability, which allows user X to overwrite files owned by Y (with useless portion of junk) when Y launchs buggy program. But this trivial (and often ignored) attack method can be easily turned into a cute, powerful weapon. Here''s an example how to perform advanced exploitation of gcc symlink bug (I choosen that one, because this
