If you want to block one of those shiny-ass ads (think workplace sanitation), here’s a few simple one-liners. (Everything’s in /etc/privoxy.)
user.filter:
FILTER: div-ads DIV ad blocks.
s/<div id="banner_box"/<div id="crap" style="display:none;"/g
user.action:
{ +filter{div-ads} }
.
Don’t forget to uncomment that actionsfile user.action from your config file.
As you might know (yeah, right), I am a proud owner of a Samsung ML-2015 laser printer, this paper-munching, smoke-exhausting hellish machine (which is, in fact, an ML-2010 re-branded for the russian and post-soviet states, so that Samsung can provide localised support).
Updating to CUPS 1.4 on Arch Linux kind of broke the printer. It’s still visible in the CUPS interface, but doesn’t print anything (the jobs are on hold, “waiting for the printer to become available”). The kernel is 2.6.31.4, usblp module disabled as per Arch newsfeed suggestion.
The solution was simple – getting to the “Printers” tab in the web interface and modifying the printer to use a different connection (the one without “usb://”).
sudo fdisk -ls

I had this happen – SA wasn’t reading user_prefs out of a proper home dir:
[12071] info: spamd: creating default_prefs: //.spamassassin/user_prefs
[12071] dbg: config: using "/.spamassassin" for user state dir
[12071] dbg: config: mkdir /.spamassassin failed: mkdir /.spamassassin: Permission denied at /usr/share/perl5/vendor_perl/Mail/SpamAssassin.pm line 1577
[12071] dbg: config: Permission denied
[12071] warn: config: cannot write to //.spamassassin/user_prefs: No such file or directory
[12071] info: spamd: failed to create readable default_prefs: //.spamassassin/user_prefs
[12071] dbg: config: read_scoreonly_config: cannot open "//.spamassassin/user_prefs": No such file or directory
I thought this was due to the way spamassassin was invoked, so I tried specifying the user and homedir explicitly. It didn’t work. I tried creating a ’spamd’ user, a homedir, changing the invocation to that:
sudo spamd -c --max-children 3 --username spamd -H "/var/lib/spamassassin/" -s stderr -D
Didn’t help.
Then I RTFMed some. That reminded me of writing something about user ‘nobody’ in exim.conf. That’s the user for which spam filtering is invoked; so if you allow per-user configuration, it doesn’t really matter that you specify “/var/lib/spamassassin” as a homedir, that’s just for the parent spamd process. For every child, the directory will be changed; for ‘nobody’ it’s ‘/’.
So I changed that line to have ’spamd’ instead, and voila!
[12071] info: spamd: creating default_prefs: /var/lib/spamassassin/.spamassassin/user_prefs
[12071] dbg: config: using "/var/lib/spamassassin/.spamassassin" for user state dir
[12071] warn: config: created user preferences file: /var/lib/spamassassin/.spamassassin/user_prefs
[12071] dbg: conf: finish parsing
I have just had this idea: since uzbl_tabbed.py in fact reads the config file for every new tab (i.e. every new uzbl instance), it should be very easy to allow tor be enabled on a per-tab basis, something I wanted badly for Firefox. Nais!
There’s a lot of outdated stuff floating on the internets. This one was most useful to me.
Basically, if you install Exim and SA from pacman, you’ve already got everything enabled. Filtering spam is done via an Access Control List (the last one in exim.conf). Don’t bother with transports unless you’re sure you want them.
Add spamd to daemons in rc.conf. If you want reject logging, append
-s /var/log/spamd.log -D check
to the string in /etc/config.d/spamd.
