A green-blue Gentoo blues

I feel the urge to teach! Pretty funny. Well. I would so much like to try it... I think I wouldn't suck at it (but I never really tried before) and I really love sharing my knowledge, more so in an interactive way. I will surely try to apply for teaching some practice classes for Unix next year. Teaching Programming practice classes could be interesting but OTOH I hate the idea of having to deal with massive amounts of Pascal code. Teaching Internet would be just boring, I guess. And teaching Discrete mathematics practices would be well over my head, at least so far. So my only hope for now is an unofficial thin-circle lecture on efficient bash (well, readline applications in general) and vim usage I was offered to someday hold on the campus. ;-)

I've been playing with Gentoo again. I've made my first ebuild, filing few bugs along the process. The ebuild tool is really awfully confusing for a newcomer. For some funny reason I kept writing <kbd>/usr/share/portage</kbd> instead of <kbd>/usr/portage</kbd>, so after some encouragement from <code>#gentoo-bugs</code> I decided to change my <code>PORTDIR</code> and see what will break. ;-)

There are some other rough edges I'm slowly discovering; on my TODO list I have an implementation of <kbd>emerge -T</kbd> which is like <kbd>-t</kbd> but shows the dependency tree with some asciiart, not just indentation (I find the indentation pretty hard to process by my optical brain centers). Also, when I'm doing a big many-packages emerge, I would like the summary of all package "installation notes" to be printed at the end, not scattered during the process where it is extremely unlikely I will ever read them. In the longer term, I want to investigate how well are the binary packages supported etc. I hope to finally learn at least some of the Python along the process. ;-)

BTW, in order to get dvifb to work, I had to restart gpm from inside the chrooted Gentoo system. But don't ever do that through the "standard" way - that will cause the dependencies to be triggered, it will happily remount your fstab (causing live filesystems to be remounted, bypassing the safety checks somehow) and so. I will try to make the system pretend those things were already done so that I can slowly restart all the stuff inside the Gentoo chroot so that I'm sure everything works when I do the final switch. I might try to switch bind to Gentoo tomorrow and also build my custom qmail ebuild (without dependencies on the other djb stuff like daemontools, which I dislike a lot).

Another BTW - if you also hate the bind9's host utility, you may find my comparison chart against bind8's host useful. On the new Gentoo system I just installed some standalone <kbd>host</kbd> utility whose output seems to be rather bind8-like. There are some glitches though, i.e. <kbd>-al</kbd> might not produce a valid zone. I might do some patches. ;-)

I will have to investigate all this funny trackback stuff, RSS feeds etc. (But it looks like at least those of my blog entries also forwarded to Advogato should have RSS feeds. Note however that I forward only articles which have prevailing technical contents which might be interesting/useful for the Advogato audience.) This weblog site could do with some CSS facelift, too. (Note to self: Remember to check why root.cz's CSS causes everything to be centered in ELinks.)

Also, please feel encouraged to tell me about any grammatical errors or awkwardness I will commit - please help improve my English! :-) (I will have to once write up about me, writing, English etc.)

Dum-tu-dum-tu-dim-ta-dum-dwamm-dum-tu-tam-dam. I should go sleep. Now.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.

If you're a C programmer with some spare time, take a look at the mod_virgule project page and help us with one of the tasks on the ToDo list!
