Portage sound notifications
The context: you run emerge with --ask parameter and, since it can take some time to calculate dependencies, you do some other thing. After a while, when you've forgotten it, you discover that emerge have ended calculating dependencies time ago and it's waiting for your confirmation when it could be already done. Has this ever happened to you? Me too. This is why I added sound notifications to some Portage events.
Chuso Gentoo Overlay
The fact is that, with ebuilds for new packages that I submitted to Bugzilla, the ones I modified with patches of my interest, those removed from Portage, some I made for my scripts and others, I collected a few ebuilds now I compile and release in an overlay for Portage.
Some of the included packages are:
Looking for modified files in Gentoo packages
Did you know that teTeX development was abandoned more than two years ago? And it's recommended to migrate to TeX Live. When I was doing so by reading the Gentoo Linux guide I found that it says: if you have modified configuration files under /etc/texmf.... How will I know that? I modified many configuration files and I can't remember which ones I've modified. I thought about using equery to check that, but I only know the command to check all the files in a package, not a single file, so I thought that it would be easier to do my own script than to read the whole equery man page.
Opera web browser with usage report tool for Gentoo
Opera has just announced through its desktop team the releasing of a new developing version for betatesting that includes a tool that makes reports about browser usage and configuration and without private information to send it anonymously to the company to improve the browser. Someone named this Opera 'Spyware', though it's a feature not present in official releases, which can be deactivated, you can read reports before sending it and the browser warns you about this the first time it's run.
