Fosdem 2010 is getting closer

The 10th edition of Fosdem is getting closer, yes .. I said 10 ,10 decimal that means ten, not two :)

It’s kinda hard to imagine that this is actually going to be my 10th fosdem , it feels weird ..

Anyhow.. Lenz just announced a call for participation for the MySQL and Friends devroom.

I`m guessing a talk on .LolSQL might be a good fit for the “and Friends” part.

FOSDEM, the Free and Open Source Software Developers’ European Meeting

Disabling DHCP on a LibVirt setup

So you have this libvirt setup and you want to have a dhcp server on the virtual machines you are playing with , or you want to have all static IP’s.

Libvirt uses dnsmasq to provide dhcp services etc and when you generate a config from the gui it will look like\

1. <network>
2. <name>piponet</name>
3. <uuid>e87d3bf1-a2e7-96ca-e131-7ae51ac033f9</uuid>
4. <bridge name='virbr2' stp='on' delay='0' />
5. <ip address='192.168.100.1' netmask='255.255.255.0'>
6. <dhcp>
7. <range start='192.168.100.128' end='192.168.100.254' />
8. </dhcp>
9. </ip>
10. </network>

If you fully remove the dhcp section, then restart libvirt you’ll notice dnsmasq running with no dhcpd on that subnet so you’ll have full control again :)

Drupal 6 , Social Networking

As posted earlier Packt was so kind to send me their Drupal 6 , Social Networking for review.

My hopes were high, I was hoping for some info on how to integrate with different existing networks, content about existing frameworks, maybe some mentioning of openAtrium or so, or integrating with Twitter or other existing platforms.

Sadly the book only briefly touches similar content, the Google API , in Chapter 7

While a good read, and a good introduction to Drupal for new users I didn’t learn anything till chapter 7 and anything after Chapter 7 ;( And I don’t consider myselve as a Drupal Expert

Changing the title of my Blog

After what google announced today it’s pretty clear who to blame as of now, no it’s not Dim0 anymore,, it’s not a Freaking DNS Problem anymore its just plain old google.

Yep Google announced they will be providing a public open DNS server . So rather than claiming that Everything is a Freaking DNS Problem, now everything is a Freaking Google Problem.

Google tracking which sites you visits while not using earch, it’s a DNS Problem , Google tracking different Google Profiles you have and matching them together indeed, another Fine DNS Proble, Google tracking what different users are working the same computer and mapping them it’s a DNS Problem,

Fedora 12 Release Party

I have a confession to make, Im a Fedora user, have been since before it existed , I remember running RedHat 4.2 on my Multia and Im pretty sur that wasn’t my first RedHat install

I`m running Fedora on my laptop and corporate desktop for the simple reason that it will provide me with a preview of what CentOS might look like in the future.

So when my inbox started to show invites of a Fedora 12 release party at walking distance from my home , I replied I’d join the party afer I had put the kids to bed.

The Serial typo

Serge pinged me today over Jabber asking hot to tackle an accidental typo in the serial number of a zonefile.

1. dig +short SOA ibbt.be
2. dns1.ibbt.be. admin.ibbt.be. 2009141017 7200 3600 1209600 432000

No really we don’t need no 13th and 14th month. Given the fact that lots of us use the YYYYMMDDID format That would mean that we’d have to wait for 20100101 to happen before we can update in a readable fashion again ..

NoSQL vs MySQL

No I did NOT post the following comment
This is ridiculous. You didn’t test MySQL, you tested a failing DNS lookup on authentication.

resulting in the follow up post :

My previous post Redis, Memcache, Tokyp Tyrant, MySQL comparison had a flaw as pointed out by this comment. The MySQL was taking a huge time for doing a reverse DNS lookup.\

But as always … Everything is just a Freaking dns problem :)

Dear Mollom,

What I would like as a feature from Santa,

I would like to be able to report a comment as URL Spam , you know the case where the content of a comment is perfectly OK, but the URL the commenter uses is a link to a NSF, pure spamming or absolutely unrelated site.

There’s nofollow etc , but to keep my site clean I’d have to report these commen
ts as spam, however when you start analysing the content of the message and comparing that content to other posts you will eventually get false positives.
