I was searching some material about group photography when I found this article on the digital photography school webiste. It quickly shows how great group photos can be made.

In my /var/log/mail.log I saw the following error:

In order to fix this execute the following commands:

 # sudo su cyrus

This will make you the cyrus user.

Now execute

 # squatter

This will index all your e-mails (more info by executing $ man squatter). This index is not incremental so you need to run this task once in a while. It might be usefull to create a cronjob for this command.

My blog has a Mac section. This Mac section is a page with one article which contains all the software. When someone uses the search functionality from this blog, and searches for VPN the whole Mac section appears in the search results which is pretty annoying. This website explains how to exclude all pages from the search results.

1. Open your WordPress admin
2. Goto Appearance
3. Click on Editor in the Appearance menu
4. On the right side of the pages click on theme functions
5. Add the following code to this section

function vibeExcludePages($query) {
if ($query->is_search) {
$query->set('post_type', 'post');
}
return $query;
}
add_filter('pre_get_posts','vibeExcludePages');

Virtual domains can be used to route e-mails from multiple domains to the correct mailboxes. In order to make it work, some changes need to be made.

First we need to edit the main.cf (on my Ubuntu server in /etc/postfix/) and add the following lines:

After checking out my mail logs I had the following error:

Aug  6 11:38:52 Nephtys postfix/lmtp[3990]: DD69A18A90C: to=, relay=none,
delay=593, delays=593/0.02/0.01/0, dsn=4.4.1, status=deferred
(connect to localhost[/var/run/cyrus/socket/lmtp]: Permission denied)

I Googled the error but could not find a fix. Finally it turned out that the postfix user was not in the mail group, which could be fixed by executing

 # adduser postfix mail

I have an external monitor attached to my iMac. Sometimes I use it as a secondary display, sometimes it is turned off. When you are already in OSX and turn on your external monitor it will not be detected immediately. You first need to open your display preferences and click on “Detect Displays”. This tweet however, shows that you can use CMD + BrightnessUp (which is in most cases F2 or fn + F2) instead.
