Pretty sure I included all of the prerequisites:

Install zookeeper package

As part of the Kafka streaming project, I installed zookeeper. Here's how I did that:

Changing Out a Zookeeper Instance - Rolling restart

Changing Out a Zookeeper Instance:

We were recently tasked with changing out 3 (of 5) Zookeeper instances without disrupting the customer's environment. I set up a test bed using 5 independent zookeeper instances with a simulated game running on another.

Using my IPAD as an extended display using AirDisplay.

Using my IPAD as an extended display using AirDisplay.

I couldn't use AirDisplay at McDonald's or Starbuck's. The wi-fi blocked local traffic. So - this is my work-around.

In a nutshell:

• Enabled Bluetooth on both and connected my IPAD to my Mac.
• Started AirDisplay on both and connected.
• When it started up, my Mac's display shrunk to the size of my IPAD. 
• System preferences (on my Mac)
• Displays
• Arrangement - un-check 'Mirror Displays' and position the small window.

Gentoo and Citrix

This is how I set-up icaclient to access Ajubeo, which uses a Citrix ZenApp server.

First, of course, was to emerge net-misc/icaclient. The only applicable USE flag was nsplugin. I don't know if it is necessary or not, but I used it for gnash and Icedtea. So "echo "net-misc/icaclient nsplugin" >> /etc/portage/package.use/package.use

Then, of course, I added the file to package.keyword with ~amd64. Emerge then tells you that you have to go the Citrix website. The message, from elogv: │Download the client RPM file x86? ( ICAClient-12.1.0-0.i386.rpm )
│        amd64? ( ICAClient_12.1.0-0.x86_64.rpm ) from
│&http://www.citrix.com/English/ss/download/details.asp?downloadId=2323812&productId=1689163 │
and place it in /usr/portage/distfiles.

Once you do that, you can emerge again, and it will extract the rpm, putting everything into /opt/Citrix. Unfortunately, this is not the end of my story.

Choose <skip to logon>

I already had a username and password, so if you don't - you're on your own here.

Click on the link for the VCloud Portal - which is really a link for the ica client.

Firefox didn't know how to handle launch.ica. So, I chose open with, and selected "other"

Then, I navigated to /opt/Citrix/ICAClient/

And selected 'wcfmgr.bin'. I also chose to "Do this automatically..."

It's still a little cranky. And when I chose to cancel the warning about being unable to connect..

And tried to connect anyway...

I was rewarded with an SSL error.

This time I tried clicked ok on the "Unable to connect.." warning and then clicked on the <Arrow> connect to selection button. Bingo

Ajubeo's login page.

Ajubeo has a great site, and I can't wait to dig into it. I just had to get past this first hurdle.

Linux Basics

I thought I knew something about Linux. All confident in my knowledge. But I didn't know Jack - still don't. But as I was reading the LPIC (Linux Professional Institute Certification) Study Guide I learned a lot. A LOT! Holy moly that book kicks ass. Now I just want to share a little of what I learned.
