Integrity checking with AIDE

As to at least do some progress in the integrity part of Gentoo Hardened (a subproject I'd like to extend towards greater heights), I dediced to write up a small guide on how to work with AIDE. The tool is simple enough (and it allowed me to test its SELinux …

Linux Sea and ePub update

I just "published" a small update on the Linux Sea online book. Nothing major, some path updates (like the move to /etc/portage for the make.conf file). But I wouldn't put a blog post online if there wasn't anything else to say ;-)

Recently I was made aware that the …

git patch apply

I recently had to merge the changes made to an upstream project with a local repository. I took out the changes as patches through git format-patch (as the local repository isn't a clone of the remote one so I couldn't just create a branch and merge) and hoped to apply …

Linux Sea now in ePub

On request of Matthew Marchese, I now automatically build an ePub version of Linux Sea for those that like to read such resources on a digital reader. Thanks to the use of DocBook, this was simply a matter of using its xsl-stylesheets/epub/docbook.xsl stylesheet against the DocBook sources …

File System Labels in Linux Sea

I have added some information on file system labels in Linux Sea (PDF). If you don't know what labels are (or UUIDs), here is a quick summary.

Most, if not all file systems, assign a universally unique identifier (UUID) which looks like a random hexadecimal string to each file system …

Linux Sea last content chapter

The last chapter in Linux Sea focuses on Using A Shell. This seems to me like a nice last chapter, as it confronts the user with the exciting world of shell scripts. I hope that the chapters in the book are sufficiently stuffed so that beginners (who are not afraid …

Linux Sea: log file management and backups

I've added two more chapters to the Linux Sea book. The first one is about Log file management, the second one about Taking Backups. They're far from finished, but I thought that those two topics are important for day-to-day Gentoo usage and shouldn't be left out of the Linux Sea …

Added "iw" support to Linux Sea

The wireless driver developers are actively working on a new wireless toolset called "iw", slowly deprecating the older wireless-tools toolset (which contains the "iwconfig" command). Kasumi_Ninja reported to me in the Gentoo Forums that it would be nice to add information on iw to Linux Sea, so I did. I …

I remain impressed by the free software community

My current personal projects, Linux Sea and cvechecker, are actively being watched by the free software community. For the Linux Sea book, I get nice feedback and ideas on the Gentoo Forums and on the cvechecker application, people such as Nigel Horne are helping out in various ways - including feature …

Feedback is, as always, very much appreciated.
