]]>The first surprise is that the wireless drivers are not included in
the install image. Running opkg update; opkg install kmod-ath9k
takes care of that. The drivers are left out by design at least on
this router and the
WRT160NL. Bonus points to
OpenWRT for allowing me to file a bug without creating an account on
their bug tracker.
The second surprise is that the dynamic dns client doesn't know about
DNS-O-Matic. I installed the
ddns-scripts package and used the following config to get it
working:
config 'service' 'myddns'
option 'ip_source' 'network'
option 'ip_network' 'wan'
option 'check_unit' 'minutes'
option 'enabled' '1'
option 'domain' 'all.dnsomatic.com'
option 'username' 'username'
option 'password' 'password'
option 'update_url' 'http://[USERNAME]:[PASSWORD]@updates.dnsomatic.com/nic/update?hostname=[DOMAIN]&myip=[IP]'
option 'check_interval' '5'
option 'force_interval' '480'
option 'force_unit' 'hours'

If lua is overkill for the task at hand, tshark also offers decent control over what shows up in the output. If you want to see all HTTP requests and their request URI and method, without any other information about the packet, this tshark command will do the trick:
tshark -T fields -e http.request.method -e http.request.uri -R 'http'
openssl x509 -in .mutt_certs -noout -text
complex-repeat) all the time. Occasionally, I find that it would be nice to reuse one of my macros across editing sessions. Turns out it's pretty easy to save the macro. Just add a line like the following to a file that gets sourced when your file is opened by ViM (This example is from ~/.vim/ftplugin/rst.vim).
let @h = "yypVr"
Now, whenever I open a ReStructured Text file, I can hit @h and my macro will run.
-S option to efficiently handle sparse files. Of course
it only works if you create the tarball with the -S option. That is all.]]>struct
ifreq. There are plenty of fields there and of course there are other
structures that I never remember. I could always look in the headers, but it
ends up being a good amount of digging before I find the real definition and
all its accompanying pieces. So, I decided to let ctags and ViM do the work
for me. I created ~/bin/update_local_tags with the following contents:
#!/bin/sh [ -d ~/.localtags ] || mkdir ~/.localtags ctags -f ~/.localtags/usrinclude.ctags --exclude=vector\*.hpp -R /usr/include >/dev/null 2>&1
Then I created ~/.vim/ftplugin/c.vim with the following contents:
setlocal tags+=$HOME/.localtags/usrinclude.ctags
For good measure I copied c.vim to cpp.vim so it would be loaded for C++
file types also.
Now I just have to run update_local_tags to generate a tag file for
everything in /usr/include and ViM automatically includes that list whenever
I edit a C or C++ file. Updating the tags file is still a manual process, I
should probably attempt to hook it into apt. Observant readers will have
noticed that I exclude vector*.hpp when generating the tags. Boost includes
a few generated header files that match this pattern and swell the tag file to
almost 750 MiB.

verbatim environment work with Beamer. Beamer can't handle the following code:
\begin{frame}{A Title} \begin{verbatim} Don't mess with my text. \end{verbatim} \end{frame}
To make it work, you need to include the fragile option for the frame. Example:
\begin{frame}[fragile]{A Title} \begin{verbatim} Don't mess with my text. \end{verbatim} \end{frame}
If you use the listings package, the same trick works for the lstlistings environment.
