How NOT to figure out a nameserver

So I was trying to install this piece of software that I wanted to test ..
It came with a weird installscript that kept telling me it couldn't ping tom my nameserver

  1. .. checking network access via ping to DNS/IP: IN
  2. ...... unable to ping: IN : ping returned: 2
  3. unable to ping DNS name server: IN
  4. 192.168.1.209 : ping returned code: 2

Now why would it tro to ping IN ?

This is why .. the scripts tries to find out my nameserver using dig

  1. root@C51 ~]# dig localhost | grep SERVER | cut -d# -f 1| awk '{print
  2. $3}'
  3. IN
  4. 192.168.1.209

It didn't expect to get this feedback from dig

  1. [root@C51 ~]# dig localhost
  2.  
  3. ; <<>> DiG 9.3.3rc2 <<>> localhost
  4. ;; global options: printcmd

Helping Sun to figure out what it wants to do when it grows up

I have to admit I`m lagging a bit on my Linux Journal reading.
So just now I read Maddog's article titled Navigating by the Sun

Bull's Eye .. I loved reading every second of it as it is so true ... I told you folks earlier that we'd love to help, but it really is time for Sun to figure out what it wants to be when it grows up :)

It's fear it's either that or down the drain with the other bunch of companies that are on the road to obsoletion.

Got interviewed by O'Reilly GMT

I got interviewed by Craig from O'Reilly GMT's for their Scenius series.

I tried to write down as much as possible of what's going on in our little country, but I`m pretty sure I missed a lot.

Weird thing is that according to Bruno's stats .. I`m not missing out on that much .. but then again .. remember what Benjamin said.

Looking back at a Decade of open sourceVirtualization

Earlier this week Virtualization.com published the first in a series of articles about Virtualization in Open Source.

In that first article I`m looking back at where we come from in the Virtualization field both on desktop and server level.

The sequel to this article will tackle today's virtualization options.

Fedora 7 Wireless weirdness

Since I first started using my Fonero I had some weird behavior with my Laptop's wireless card. Intel PRO/Wireless 3945ABG Network I could usually see 2 of my 3 wireless networks but not my MyPlace network. Sometimes I couldn't see any wireless network untill after a rmmod iwl3945 modprobe iwl3945 sequence.

Somewhere last weekend I was fed up with my slow booting laptop and decided it was time to clean up my bootorder and remove unused services that I had installed for test purposes only from it's boot procedure. One of the steps I took was removing the default enabling of my wlan0 interface.

The result was pretty astonishing, not only is my laptop booting much faster, but also whenever I now manually start NetworkManager it actually finds the MyPlace network and connects to it.

Yes I know I should upgrade to FC8 someday , and probably this is a known fact/fix but I never bothered to look further. Lazyness you know ;)

What if Bill

In What if Bill turned Restaurateur, there is a funny quote

And GEM users and DESQview taskswitchers would be tapping away quite happily on them, wondering what all the fuss was about.

What fuss is he talking about ... like most normal people wanting to Taskswitch back in those days you went from DESQview/X to Linux and never looked back.

I've never used the other thing and I`m not missing a single thing ...
Must be this parallel universe thingie...

3 strikes

I'd call this the 3rd strike and everybody knows what happens next

Marc Fleury has some good answers to the most clueless industry reporter around, starting with:
Spring is touting itself as a JBoss replacement. Smart PR, but false. Spring is a development framework comprising wrappers and dependency injection on top of Hibernate and Tomcat runtimes, both developed, and monetized by JBoss.

You can drop some balls, no one can keep track of what's going on in Open Source land, it's difficult enough to track what's going on in MySQL, Drupal, Virtualization and Distribution land but if you realize you don't have the whole picture (like not really knowing how the different tools compare to each other) please keep quiet.

Social Network Annoyancies

Don't you just hate it when these social networks or bank sites send you an email
"You have 1 new message" on XYZ ..

Just send me the f*[k1ng message you idiots! Thats why we invented email ..
I don't want to go to your crappy excuse for a mail interface while you should just deliver the message in my Inbox.

Thank you for fixing that bug.

Oh and can someone please explain the folks over at LinkedIn about RSS.

It's over

Moshe announced that tomorrow the
openMosix project will end.

We had a great time.. I learned a lot .. and I got so see a part of the world while working on openMosix.

There are a couple of people on #openmosix that are still trying to build a 2.6 release ,
not sure if they ever succeed.. If they ever reach something that's worth documenting.. I`ll see if my schedule allows to pick up the job again ..

Till then .. I`ll be working on other projects..
