Hi,

I noticed that my Ubuntu 11.10 Oneiric Ocelot machine was complaining about:

$ php -v

Outlook for Mac: Error 19906

jeroencoenders — Wed, 11 Apr 2012 06:34:48 +0000

Just wanted to share my experience with Outlook for Mac regarding error 19906. In my case it was preventing all downloading of e-mail and sending out e-mails.

The resolution that worked for me was removing all shared calendars by selecting each of them and removing them from view.

Hope that this helps you.

Apt-get behind a proxy in Ubuntu 11.10

jeroencoenders — Sat, 03 Mar 2012 12:32:23 +0000

When you are behind a proxy on Ubuntu 11.10 and would like to update your system:

Edit the file /etc/apt/apt.conf.d/02proxy
Add the following line to this file (Of course replace the username, password and proxy ip address)
```
Acquire:http:Proxy "http://username:password@proxy:80";
```
And of you go:
```
apt-get update
apt-get upgrade
```

Thanks to:

Update:
If the above does not work, you could try the above in /etc/apt/apt.conf. This sometimes works with the above doesn’t.
