The future of Open Source Groupware

So Xandros acquires open-source e-mail vendor Scalix, does this mean we can write off Scalix as a potential solution to the future. We looked at Scalix but decided not to go for it afterall. I fear for their future .. as I don't think Xandros has a big future left .

On the other hand.. I`m still waiting for OpenXchange to be bought by some Linux distro.
Given their move away from Suse to Ubuntu.. I doub't if the 9 months old rumours they would be going to RedHat will come true.. probably not.

So where does that leave us in the Calendring area.. ?

Red Hat Magazine | Simple SVN: Just enough to get started.

Red Hat Magazine
runs an article titled Simple SVN: Just enough to get started

It's about time system administrators also learn to use version control for their own configuration files and not just for the code their developers are using.

I just hope more people read RedHat Magazine and realise this than the small crowd on this blog :)

Windows Only VPN's

Can anyone explain me how a "VPN" connection that only works from a Windows platform can be considered secure ?

No sorry .. I don't get it.. you want to create a secure network environment and the only way to log on to that network is via a platform that's insecure by design.
Beats me. Still too much people trust it.. weirdness. Maybe I should refocus on security again ..

openMosix Project End of Life Announcement

Bruce just posted the openMosix Project End of Life Announcement
effective March 1, 2008

We decided it was better to declare openMosix dead than to keep hoping someday we got more time to work on it .

I want to thank everybody who , over the years, has been contributing to the documentation, has been listening to my talks at different conferences and also everybody who has been writing and testing the code for the different releases.

I still have a high interest in SSI and other HPC techniques, and most other topics I`m involved in are related ,Virtualisation, Large Scale Deployment / Management , Database Clustering, HA in general, but as Moshe states it .. that's also the direction lots of the key developers went , so I`m sure we'll meet again .

LugRadio Live 2007

Seems like I`m putting LugRadio on my todo in 2008 list. It's not like I didn't have a good reason not to go this year :)

The iPhone is obsolete!



Now stop blogging about the iPhone .. we don't care.


We do care about an open phone that you can acutally use, without a hammer.

Steorn's Orbo

Today lots of people are waiting for the launch of Steorn's Orbo "free-energy" machine

I first heard about Steorn at the evening before the NLUUG Conference this year from some Dutch guy who was convinced it would be a revolutionary change in how we will produce energy .

Steorn promised us Infinite Clean Energy , but could your datacenter run on it ?

Time will tell..
EDIT: Time told us. , damn I hate Vapourware !

SourceForge.net: new plugin: Fully automatic installations for openQRM

Matt just announced a new plugin: Fully automatic installations for openQRM

Altough it is not yet 100% functional (only Kickstart today) this plugin is about to take away my biggest concern against openQRM, namely the fact that you had to use images and you still coudn't create a reproducable new installation.

Can't wait to setup a workshop to actually boostrap an openQRM server , and manage it with Puppet.

Virtualization and License Compliance,

It used to be the embedded area where the GPL didn't mean that much, if a hardware vendor had to choose between
complying to the GPL or paying a license fee for VXworks or anohter embedded platform the choice for Linux and not bothering to comply till Harald knocked their doors was an easy one. Things are starting to look better in the Embedded area now, we're not there yet .. but things are improving.

Today I read the article on /. (bias warning!)
about SWSoft not complying (yet)
and I tought back about the early days of Virtual Iron, the rumours went away but iirc there seemed to be some issues there also regarding their migration code and where it came from.

So .. it she virtualisation area the new place to violate the GPL ?

I hope not .

Desperately Seeking Xen ? Not looking the right way !

Tarry pointed me to Desperately Seeking Xen, Jeff Gould is wondering about the adoption of Xen.

But what I'd really like to know is - who's actually using this stuff in production? And I mean actual end-user organizations, not ISPs or hosters. Based on the absence of Xen-related chatter, my guess is that production users of Xen are still few and far between.

I think he isn't even looking. or definitely looking at the wrong places,
Well.. if he is a Director at a Research company .. he should know better than to look for
Press releases and Customer reviews. Jeff, welcome to 2007 this is the Open Source decade. People don't buy products anymore.. people don't run to their vendors and ask for a rebate in return for a fake case study. People just use the technologies available freely.

You have to compare the adoption of any new open source technology to the adoption of Linux and open source in general. Did you see press releases in the early years from big vendors touting they were doing implementations ? No those only came a couple of years later but the adoption was there.. One day .. Apache clearly overtook IIS, but how many vendors were sending out press releases about their Apache successes ?

So you are looking at sales from Xensource and info from Novell and RedHat customers talking about how they use Xen. Please stop looking.
You won't find any stories from Ubuntu or CentOS users on how they use Postfix as a core component in their network either.

I don't doubt that hundreds or perhaps even thousands of Linux geeks around the world are kicking the tires of Xen, especially those using the free distributions that include it, like Fedora. But that doesn't make Xen a serious threat to its rivals in actual deployment in real-world data centers, at least not yet. By any measure, VMware is still the 8,000 pound gorilla in this market.

This is where you go wrong.. you don't know what they are using it for. They might be using Xen in a production environment at a huge bank or telco, not telling you because they are perfectly happy with the way it is running. Nobody will ever see a dime (apart from the guys paycheck) for having implemented 200 CentOS based Xen servers. But they are there (trust me I know they are there..) and both VMWare and XenSource are loosing business there, altough probably not the business they want.
Are these deployments showing up in any sales figures ready to compare the "sales" of Xen vs the sales of VMWare ? No , and they never will

For those who believe that Xen will one day overtake VMware, these numbers set the bar pretty high. For the moment, there is nothing to suggest that Xen is achieving anywhere near the growth rate it would need to perform such a feat, even in the distant future. Of course, all great things start out small, and there is still plenty of time for Xen, since we are by all indications only at the beginning of the great virtualization wave.

So you have no valid benchmark to see how fast the adoption of Xen is growing compared to the growth in market for VMWare.

Personally I think the end of the virtuallisation wave can be really close. It's only a matter of time till a hardware vendor decides to put a Hypervisor in his firmware, oops ..
lemme rephrase.. till a mainstream hardware vendor decides. Looking at the industry they are probably being told to hold of by the current players in the virtualisation market because they are still selling soon to be invisible technologies.

As for the different new open source virtualisation technologies , they will all fall in the right place. KVM has other features than Xen, more targeted towards a Desktop audience rather than a server audience. It's not like you are still supporting your soundcard and running X on every server you deploy .. so different tools for different purposes.

But I keep wondering .. if for every article written by someone outside the community claiming there is no use of a certain echnology I got a penny.. would I'd still care about them ?

PS. Reference studies for Xen deployments on demand :)
