Who Am I?

Hi,
my name is Sinisa Sokolic.

I started my professional IT career in 1999 at the age of 20.

There is one thing I can remember as if it was yesterday – when my former boss said to me in 2004: “Tweak every thing you can on this machines, I want maximum user density.”

It was my first contact with Citrix Metaframe XPe. I was afraid and had shit in my pants. This was the baby of my boss and all of his pride and I knew he would cut off my hands if I would do anything stupid to it.

The farm I had to tweak was a bunch of about 20 Windows 2000 Servers with 2x 1,33 GHz processors, 4 GB of RAM and all machines were multihomed with a 100 MBit switch connected to all servers and a file server cluster because the rest of the network had only 10 MBits.

All that he gave me was a printed copy of Rick Dehlingers Tuning tips for Windows Terminal Services. I still have this copy of it printed out to keep the memories.

I started to try and implement the tips and learned that not only Rick Dehlinger existed in the world. I liked that time very much because I learned a lot.

And when I finished I had maximized user density from 20 to 26 users per machine. It was awesome.

Today I have spread my experience from Citrix to VMware to Microsoft and AppSense related products and technologies. I work as Cloud and Virtualization Architect in different projects at RIS Consulting GmbH in Cologne/Germany

To sum it up: As Rick Dehlinger had done it in the past I want to take part in the community and give something back to it.

Therefore I started this blog.

I hope you enjoy it.
