my mom on linux
My lovely mum was used to a Windows 2003 system which was fully filled with crap programs she never need. With some assistance she got quite familiar with email, surfing in the net, capturing and modifying pictures from her digital camera, scanning paintings, chatting with skype and so on.
So it recently happens that her system got unstable. It turned out to be a physical harddisk-failure crashing the system after a random amount of time. Luckily my mom made her homework and had all her personal data burnt to CD's already. Good mum, I am proud of you.
Since I did not plan to futher maintain any windows system (not to mentioned that I for sure won't install Vista on her computer) I switched her to Linux :) ... my mum seemed to got a bit afraid of this idea, anyway.
I bought a new harddisk and an additonal external USB harddisk for her, replaced the bad disk with the new one, gave the latest Ubuntu CD to my mom and told her :
"Now, please install your computer".
... she looked at me as if was from outter space. I quickly convinced here to start.
So, you know what happened. In less than 10 mouse clicks she had her new Ubuntu Linux-system up + running.
She asked : "That was it ? The installation is already finished now ? Unbelievable ..."
With some help she then put all her personal data back, enabled the mediaubuntu repository, installed skype, get used to openoffice (within some minutes) and enabled the remote-desktop option so that I always can help her from remote. Worked out pretty well I thought and was curious if she adadapts to it and how long it will take.
Now a good week is over since she moved to Linux and here are some quotes from here :
"This Linux made my computer a lot faster than before."
I asked her if the new system is kind to her and she replied :
"Oh, yes, very kind. It is much more convinient and easier to use now"
She told me :
"Really nice, this Linux system. To be honest I was quite afraid that everything will be different and I would need to learn lots of things from the scratch. But no, things are simple to understand and I am already back working with it like I was used to before. It is just easier and more transparent now."
Last thing on my todo list for her is to install a simply rolling backup cron job using rsync to backup her home directoy on the external usb disk. No big deal and we will all slepp better then.
My resume is that switching my mum to Linux was exactly the right thing.
Now her system is maintainable and she really starts to like it very much.
Another positive side-effect is that the friends who previously helped my mum with her computer do not have any clue from Linux so they won't be able to install any useless crap-software she do not need anyway.
Mum is happy and me too, hehehehe. Thought it would be a good example of Linux arriving on the Desktop.

LCA2008: Hacking on lguest (2)
Lguest is a new and very light virtualization technology created by Rusty Russels.
It is very fast and basically allows to run "linux on linux". The video shows the lguest-host Qemu-image which was provided by the lguest-tutorial at linux.conf.au 2008. After the lguest-host is booted up a lguest virtual-machine is started by a simple user-space launcher. It also shows the simple hypercall printing out "Hey Ho Lguest" which was implemented during the tutorial.
Cool stuff by Rusty !
LCA2008: Talks finished, Google-party and Open-day
... sadly we noticed that somehow the catering service stopped giving out beer at 8.30 p.m ! What the h... ??
Sorry, but no party without beer so we grouped up with some people and found a nice pub in Brunswick. That was fun and we had a great night.
But LCA 2008 is NOT over yet but opening its doors to the public today. Lots of interesting projects will be presented and everybody is invited to join the "freedom lovers".

LCA2008: Hacking on lguest
The lguest tutorial provided a ready prepared Qemu filesystem so the participants could bring up their own lguest-Hosts easy and start hacking on the the different tutorial tasks. What a fun. Even myself was able to implement a new hypercall printing out some string on the lguest console at startup (and i do not consider myself a kernel-hacker).
Lguest is definitely an interesting project and i am curious how it will find its place along the other available virtualization technologies used today.

Fire alarm at Linux.conf.au 2008
Luckily it could be resolved quite quick, nobody got hurt and the talks continuing.
Funny thing was that the alarm ring seemed to be in a kind of high-available mode because it tried to restart again and again even after it has being turned off.
.... reminded me to yesterday when a small bread on the toaster in the hotel room immediately started the fire alarm. I was flying downstairs to the reception because i read before that it is directly connected to the fire brigade and that you have to pay a real high fine if they are coming out. Luckily it was only the smoke alarm in the room and not the fire alarm of the hotel. Puuuah.
Now i am looking forward to the Penguin Dinner tonight which will be at the tonight at the night market in Melbourne. The social events (and of course the partners program) of LCA rocks !
Combining the virtual and real world
He demonstrated how to interact with the virtual objects inside Second Life using "real world" objects using various small hardware-hacks and making use of the famous Arduino microcontroller. One example was to use a serial RFID-reader, connected to a network socket, to open/close a virtual door within the Second Life virtual reality (John actually has a RFID chip implanted in his arm).
Actually his talk remembers me to my "Data-center within Second Life" project which i was working on about a year ago. My idea that time was to rebuild a "real world" data-center infra-structure inside Second Life, connect it to an openQRM server and enable the administration of real servers from within Second Life.
Basically it is about using the 3D virtual reality of SL as a user-interface for real world objects and/or applications. It worked out pretty well and i even gave a presentation including a live-demonstration within Second Life.about this openQRM sub-project
Here some links to videos of this virtual presentations:

CIOs and IT Managers: Are you willing to adopt virtualization now?
CIOs and IT Managers: Are you willing to adopt virtualization now?
I fully agree with him about the challenge to adopt to virtualization today. It adds another layer of complexity to the IT infra structure which current tools are not ready to manage in a flexible and transparent way for the system-administrators.
Nowadays a common data-center is normally still very static, powered by lots of physical systems with a custom installation, configured and maintained by a couple of loosely connected tools.
Virtualization claims to provide the option to move to an appliance-based deployment via virtual machines to ease-up deployment and to better use the resources of the data-center. Since bringing up a virtual machine more or less just requires space on a storage for the virtual-disk the need for high-end NAS and SAN data-storage systems raises.
On the other hand virtualization adds another level of complexity.
Systems and services migrated to virtual machines still needs to be setup, monitored and maintained just in the same way as for physical servers.
With a raising number of servers (physical and virtual) it gets more hard to fulfill this task in a successful and efficient way.
Migration itself (e.g. from physical systems to virtual machines) can be a really tricky thing too since most virtualization technologies are still lacking this feature.
Another difficult task for the IT-department is to decide which of the current available virtualization technologies to use.
There comes the question if it is not a disadvantage to be limited to a single virtualization technology ?
To my mind it is because of two reasons :
1) Different virtualization technologies are available today.
There is "full-virtualization" (e.g. Qemu/KVM), "para-virtualization" (e.g. Xen) and "light-virtualization" which is in most cases based on a process-isolation (e.g. Linux-VServer, Solaris Zones).
Each technology has its advantages but also its "limitations".
Now, in a common data-center we normally find lots of different applications with custom needs e.g. a web hosting company may have hundreds of "idle" customer web-servers plus a couple of in-house oracle data-base servers.
For the web-servers it would make the most sense to choose one of the "light-virtualization" or "para-virtualization" technologies to limit the virtualization overhead to a minimum.
Using "light- or para-virtualization" a single, physical machine can easily host several hundreds virtual partitions.
(please see "Building a virtualized web-farm with openQRM")
On the other hand the data-base servers are CPU, IO and network intensive so choosing one of the "full-virtualization" technologies would be a benefit.
So one reason that it is a disadvantage for the IT-department to limit themselves to a single virtualization technology is that the virtualization type should be selected according to the application needs.
2) The other reason is to simply avoid vendor-locking.
So if it would be best to choose the virtualization technology according the applications and services the IT infra-structure does not only need to support several different virtualization options but also provide an option to move from one virtualization type to another and also the possibility to migrate a virtual machine back to a physical system.
Today, if you try to move a e.g. VMware-partition to Linux-VServer or a Xen-partition back to a physical machine, sure there are eventually some custom utils, scripts and howtos available which will help but at all this will be an "adventure".
Both situations, the common static data-center using physical servers and the new virtual-appliance-based infra-structure are already quite tricky to manage on their own but with the move to virtualization the system-administrator today even needs to handle "mixed environments", both physical and virtual.
To my mind we would need a tool which seamlessly integrates with the different virtualization technologies and conforms resource-planning, deployment and management of physical systems and virtual machines. This tool should also integrate with modern storage-systems to take the full advantage of fast-cloning servers for rapid and automated provisioning. It should have an open- and plugg-able architecture so that custom third-party utilities can be integrated in an easy way to combine them into a single-management console for the whole IT infra-structure.
If you are interested in such a tool you may want to take a look at the openQRM project which is exactly providing this kind of framework.
Enjoy !
