In a time when many tradeshows are experiencing lower then normal attendance the 8th Annual Southern California Linux Expo (SCaLE 8x) had record attendance this past weekend in Los Angeles. I was there exhibiting and conducting a community training day for Zenoss and was very impressed by not only the quality of the program but the enthusiasm of the attendees.

Here are some of the highlights:

On the Friday before the main SCaLE expo and speaking program starts many people hold …

A recent pitch from the folks opposing Oracle’s ownership of MySQL via acquisition of Sun Microsystems got me thinking. The plea, ‘Oracle can have Sun, but not MySQL’ may make sense to some, but to me it speaks to the irony of closing out Oracle or any company or anyone from open source. Upon further reflection and given 2010 is off to a roaring pace of M&A, I also began to wonder what the impact of the ‘Save MySQL’ campaign could be on open source in M&A, particularly if it was to successfully derail the acquisition or somehow decouple MySQL from Sun under Oracle?

What would it mean to carve out the open source projects, components, teams and support from companies involved in mergers and acquisitions over …

Of course it’s not quite that simple. I’ve just decomissioned an old Red Hat 7.1 box (hosted dedicated server) that had been in service since 2002, so about 7 years. Specs? Celeron 1.3GHz, 512M, 60GB HD. Not too bad in the RAM and disk realm. It did a good job but goodness am I glad to be rid of it!

Not having that box online is safer for the planet, although it (perhaps amazingly considering the age of some of the externally facing software components) has never been compromised – I consider that mostly luck, by the way, I’m not naive about that. But it’s not easy to move off old servers, it’s generally (and also has been in this case) a lot of work.

Of course hosting has moved on since 2002, places like Linode offer more for less money/month. Of course they virtualise (Xen based in this case) and that’s not been my favourite (particularly for DB servers but depending …

So the cat is out of the bag,

As of today Inuits is rebranding to Pinuits,
The press release is here

We've had good feedback on the new name so far. Different people told me the name matched better to what we are doing . Actually my wife thinks our new name is much better as at least the Pin in Pinuits refers to our favourite Tux again ..

Finding an appropriate name for an Open Source consultancy company, with focus on Linux, Open Source Monitoring, MySQL, Open Source Virtualization , Large Scale Deployments , High Availability and Drupal, isn't easy .. you want to show both community involvement and professionality. And find a domain that's still available.

Here is my experience trying to run OpenBSD with XenServer 5 Enterprise.

• XenServer console doesn’t function properly as it keeps overlaying text displayed previously or anything you have typed into the console. Makes it very difficult to read and see what you are doing. As well it appears numerpad with numlock on does not work either. The best work around is to SSH into OpenBSD.
• Receiving the following error messages at boot up, “clock: unknown CMOS layout” and “rl0: watchdog timeout”. Yes the NIC is being detected as a Realteak 8139. If I check /var/run/dmesg.boot out of the two error messages I only see the “clock: unknown CMOS layout”. So I would assume the watchdog timeout message occurs after initial boot sequence.

or timebound ? or don't you have any load on your DB at all ?

I personally don't see many reasons to virtualize your database, apart from the , we plan to start small and scale out, or the we need it now and we don't have the hardware yet , putting your database on a virtual platform where you have to share resources with other virtual machines doesn't really sound like a tempting proposition to me. Small, almost idle databases , maybe. But enterprise production level databases no thnx.

Sheeri Cabral also mentions the above reasons .. and there also .. Enterprise Production use isn't listed.

Databases typically require a good amount of memory , and steady disk access.
So if you are in a production environment with a fairly loaded database, would you want a 4Gb machine with full direct memory access, Or 3.5Gb of virtual …

Fosdem is over .. and it was ... overcrowded :(

Honestly trying to squeeze into an overcrowded bar, then on saturday overcrowded rooms, or even not being able to enter that room (Mozilla and Embedded) , Fosdem is starting to become the victim of it's own success.

Some people are suggesting Fosdem to move to the Arenberg campus in "Brussels-East" dunnow if Leuven can actually host enough beds for Fosdem :)
However the Beer event problem would be solved but Philip will have to make arrangements with 'The greatest bar of Western Europe"

The talk about Xen on ARM was interresting however the grande finale missed, the MiniOS just didn't boot :( Kettle was interresting …

I recently received a review copy of the book "Xen Virtualization" by Prabhakar Chaganti (Packt Publishing) and finished reading it a few days ago.

The subtitle "A fast and practical guide" is a matching description - I managed to read the ~130 pages over the course of a week. The book is by no means an exhaustive reference manual, but it gives the reader a good overview about Xen and assists with performing the first steps and getting started.
