A friend of me, Pieter Colpaert, is one of the core developers on iRail. I don’t know if you all followed the buzz around iRail, but iRail is more alive than ever!

And because they want to get that extra push, they are organizing a hackathon at Whitespace on Friday 17 September from 18h. I won’t be able to make it because of Fudcon, but I want to give them my full support!

More information is available on the Whitespace wiki

I’m pretty excited about it because there are some great things on the program! To start with there will be the normal barcamp sessions and hackfest like you are used to from normal fudcons, but as an extra there will be some lightning talks before the hackfests. This way people can attract new people to their hackfest, and introduce small and new project to a broad audience. As always with FUDcons everyone is free to host an own session.. so if you have something cool and/or important to share with the world, just add your session to this list.

If that didn’t convince you yet, maybe the following activities that are planned will:

• Friday: Wired Dream Party
• Saturday: FUDPub
• Monday (if you want to stay): visiting CERN (99% sure)

And if that isn’t good enough, we combine our conference with FrOSCamp, so you can be sure you won’t only see Fedora people, but people from all sorts of projects and cultures..

I’m sure it will rock!

Did I convince you now? go and sign up here.

Hope to see you there

something I would like to know before I leave on Tuesday, is there someone who wants to take me back (with a car) to Antwerp or Ghent? That would make things easier for me..

see you there, I’ll be attending sessions from Wednesday.

here are my slides:

How to live with SELinux

Dag found that Linux is mentioned in the last publication of De Kiekeboes, a flemish comic for children.

apparently he is running RHEL 5 next to Win XP Pro.. I wonder why he still needs Win XP then? But I think you agree this is a small win for Red Hat and Linux as a whole.

The workshop will start around 7pm, and will take place at 0×20. Everybody is welcome!

• CPU: Intel C2D E6300 @ 2.8 GHz
• ram: 7986 MB (667MHz)
• ASUS P5Q PRO
• gpu: MSI NS7600GT (256MB ram on board // passive cooled)
• hard disk: 7x WD 1TB black (hw raid 5) + 2xMaxtor DiamondMax10 (soft raid 1)
• psu: Corsair 450W
• raid controller: ARECA ARC-1222 PCI-Express X8

I know the GPU is ‘a bit’ overkill, but I had this card laying around, so I might as well use it then

In a series of posts I will try to explain how I configure my server. If any of my readers have good ideas, let me know!

these are the things my server has to do:

• being a hypervisor (KVM) [Centos]
• firewall [Astaro]
• mail server (Zarafa)[centos]
• file & media server (Samba)[centos]
• integration of Zarafa and Samba with Openldap
• easy deployment of vm’s for testing (cobbler / koan)
• monitoring (nagios)
• package building (koji & mock) [fedora 13]
• access from outside the network (vpn)
• maybe things I will think of later, of suggestions you guys give me.

feel free to call me stupid, but I would rather have tips or cool information on the things I want to do. I already have some experience with most tools, but maybe the ‘best practices’ are different. I need these tools, and I want to challenge myself.

If you are interested in joining us, please fill in the doodle. Note that we prefer to not hold the workshop on a Thursday, but is a possibility.

The workshop will last something between 3 and 4 hours (depending on # questions and interest) and will cover the following topics:

• Why run SELinux?
• SELinux contexts
• Policies
• SELinux auditd & logfiles
• booleans
• context en labeling
• file systems
• Confining Users
• extra questions?

If you want to participate you will need an SELinux capable system you can play around with (I will be using Fedora / CentOS). You are encouraged to use one of previous mentioned systems too. You can install a distro in a virtual machine of course. As an extra we could try to configure SELinux on debian too, but I never tried that before. You can find a howto here.

the slides will be in English, but I can speak Dutch too. it all depends on the audience

I hope to see you all there!

I was wondering if this too could become a Fedora meme? let’s try it!

These are the books I am currently reading:

• Fedora 13 security – enhanced Linux (chapter 4)
• Foundations of IT service management (chapter 3)
• Red Hat RPM Guide (chapter 7)
• Linux Fundamentals (chapter 11) (but because I already know most of it, this one goes lightning fast)
• The productive programmer (chapter 3)

Books laying around here that I still have to read:

• CCNA: accessing the wan
• Getting things done (but maybe I should read this one first )

who’s next?

       a = b
   a + a = a + b
      2a = a + b
 2a - 2b = a + b - 2b
2(a - b) = a + b - 2b
2(a - b) = a - b
       2 = 1

On first sight you might think it is correct, but if you look a little bit closer you can easily see the error!
let’s try it again:

       a = b            //true
   a + a = a + b        //true
      2a = a + b        //true
 2a - 2b = a + b - 2b   //true
2(a - b) = a + b - 2b   //true
2(a - b) = a - b        //true <=> 2a - 2b = a - b <=> a - b = a - b <=> 0 = 0
       2 = 1            //false (should be 0 = 0)

that’s it for my ranting =)
