SELinux seems to be one of the technologies available with great potential but with little or no user-acceptance. I have often ended up disabling the security features due to limited time reading up on, and then configuring the it to fit my needs. However I thought I should give the policies delivered with CentOS a go.

To get started with the targeted policies have a look at the selinux and httpd_selinux manual pages:

$ man selinux
$ man httpd_selinux

Those two manual pages should give enough information to get started.

Something I find myself wanting to do is enabling CGI script to execute and then granting those scripts access to files. To run /path/to/file.cgi as a CGI script reading data from /path/to/read/directory and writing to /path/to/write/directory execute:

# chcon -t httpd_sys_script_exec_t /path/to/file.cgi
# chcon -t httpd_sys_script_ro_t -R /path/to/read/directory/
# chcon -t httpd_sys_script_rw_t -R /path/to/write/directory/

For debugging purposes SELinux for Apache can be disabled by:

# setsebool -P httpd_disable_trans 0
# service httpd restart

To list out what contexts files have use the -Z for ls:

$ ls -Z

Moving towards Java land I recently took a SCJP certification and got reminded about how hard it is to measure knowledge and skill. Second up is, even if it would be possible to measure it in a good fashion what would you do with the score? Consider a person with both tons of knowledge and skill, but without sense for quality or ambition to do a good job. What would such values give you then?

Not providing any solution here, but it seems as if it is harder to give people a sense of quality and motivation to do a good job compared to improving their skills…

Today I did some updates on the Gal Gtk+ interface making use of some new shared code between the different player implementations. Showing the three level version of the interface (which is how the curses interface is laid out) in #pekwm (irc.freenode.org) it was suggested that it’s “better” to have previous two-level view.

Conclusion, as always, user interface design is tricky and for some things an extra configuration option is worth it!

I’ve finally gotten around getting myself a tattoo, was this years x-mas gift to myself. It’s  a PI (3.1415) in the back of my neck. Check it out:

Not all that much going on in the pekwm world these days, there’s been some cleaning and bug fixes but I have still not done any work on 0.2.0. :-/ Anyway, I stumbled across a nice blog post on living with pekwm, check it out!

After more than 4 years working for FreeCode I’ve decided to move on looking for new challenges.  I’m beginning at Bouvet where I’ll be focusing more on development and less system administration (if everything goes as planned).

While at it, I also have a great ambition of not working all that much giving myself time to do more development during my spare time, let us see how that goes. Right now phew-0.1.0 and ganeti-manager-0.1.0 is just around the corner so it’s not going all that bad. ;)

Found a “fun” page on incise.org named “not so tiny window managers” the other day about window manager sizes and got the inspiration to do a incomplete follow up.

The following “measurements” have been done on NetBSD 5.0 AMD64 (GCC 4.1.3) and SLOC has been measured with SLOCCount version 2.26. Binary sizes are sizes after stripping with –strip-unneeded.

The number of lines of code and binary size does not represent how fast, how many features or how much memory the window manager uses at runtime.
