I actually have my own CVS repo for all of this stuff, which makes updating them and keeping them in sync across machines simpler. Well, for some value of "simple" at least). - chown -R awm.users /usr0/awm - I usually set up "afs-home" as a symlink to /afs/cs/usr/home/awm - test: best done by opening a new window to login as awm, so if it doesn't work you can still correct things in your still-open root window.

You don't need to worry about the shadow file because it's only relevant to passwords and account expiry stuff. Also, there's no need to use vipw, because there are no (real) race conditions to worry about. Then do the rest of the stuff Dan discussed. -Paul On Fri, 1 Nov 2002, Andrew W.

If you receive your mail in SCS, then you can make use of the spam filter installed (but not normally activated) to label messages which are, with high probability, spam. Here's how: Edit the file .maildelivery in your AFS home directory. Assuming your username is bovik, add these lines: # file tagged spam in my regular mail spool addr bovik+spam > ? /usr/spool/mail/bovik # tag spam and resend to bovik+spam * - | ? /usr/local/bin/spamassassin-maildelivery -S bovik+spam at cs.cmu.edu # send zephyr notices only for nonspam default - | R /usr/local/bin/zrcvalert $(size) (If you don't care about zephyr email notifications, don't worry about the last two lines). Now, on your maildrop machine (ux7 or ux11 or whatever shows up under "Forwarding bovik as" when you do a "finger bovik at cs.cmu.edu"), run this: spamassassin -t < /dev/null (it might take a while, just let it finish).. That's it! What this will do is put the string "***** SPAM *****" in subject lines of messages it classifies as such. It has a fairly low false-positive and false-negative rates. But you can add blacklists and whitelists in the file .spamassassin/user_prefs to refine it. You can also do more interesting things with the flagged mail - file it in a folder you only read occasionally, forward it (or the unflagged mail) to an external mailbox, or simply discard it.

Jean From komarek at andrew.cmu.edu Thu Nov 14 00:44:52 2002 From: komarek at andrew.cmu.edu (Paul Komarek) Date: Thu, 14 Nov 2002 00:44:52 -0500 (EST) Subject: [auton-users] latex tricks Message-ID: There are some tricks you can do when compiling LaTeX documents that allow for better-looking conversions to PDF. 1) Instead of "latex foo", do "pslatex foo". pslatex is a shell script that wraps latex. It is part of the tetex distrobution of LaTeX, which is the standard for GNU/Linux machines. It may be available on other platforms. All that the shell script does is invoke latex with a few command-line parameters that cause your .dvi output to specify scalable Type 1 fonts instead of the normal (dynamically-generated but statically-sized) bitmap fonts. Thus your document's fonts will remain scalable after conversion from Device Independent format to PostScript or PDF format. pslatex has two other advantages. The fonts are ever-so-slightly smaller, giving you an extra paragraph or two on an eight page journal paper (guess how I know this =-). Also, the PostScript and PDF files produced from the .dvi files made by pslatex are usually smaller, making network transfers appreciably faster. 2) Instead of "latex foo", do "pdflatex foo" pdflatex compiles LaTeX source more-or-less directly to PDF format, and no .dvi files are produced. It is a binary application with several interesting-looking features. You might want to read the man page. I don't usually use pdflatex, because I like proofing my documents in PostScript form using gv; xdvi doesn't handle rotations of included eps graphics, among other deficiencies, and existing PDF viewers don't suit my tastes for quick-turnover previewing either. That's why I know next-to-nothing about pdflatex. -Paul Komarek From komarek at andrew.cmu.edu Thu Nov 14 14:48:58 2002 From: komarek at andrew.cmu.edu (Paul Komarek) Date: Thu, 14 Nov 2002 14:48:58 -0500 (EST) Subject: [auton-users] Loki upgrade Message-ID: Hello everyone, We (finally) received the new cpu and psu for Loki, our DEC/Compaq/HP ES40 Model II monster machine.

I used "prosper"-- it's essentially totally trivial to create slides-- just copy and paste regular old latex in and pick a style file. I think it's about the easiest package around to use. It relies on "pstricks" which I think most latex distribution include and is a very slick way of drawing graphics, especially graphical models. --drew
