Cloud Foundry Test - 1

Cloud Foundry is a great offering from VMWare - Platform as a Service (PaaS). It allows you to host applications (your code) in certain technologies (ruby, perl) without any hosting or administration. As a "lazy developer" this is heaven, since all you need to worry about is your code working, you do not need to maintain environments...

However, even to gear for such a test, you need an environment, which was my trigger to go with Linux. So...

Download VMWare Workstation and install
Download Fedora iso
Create new VM and install Fedora

so far so good...then there are fun troubleshooting exercises, like:

how to update the sudoers with my account
setting up the linux display options etc .. yawn ..
sudo yum install gcc make git
...

Windows 7 Do NOT Remember folder settings

There used to be an option in prior windows version where under Folder Options, you would "NOT remember" the view settings. This way, the browsing would be uniform, unless you wanted to change it. I found a way to do it in Win 7. Go to Folder Options\View and click Apply to Folders. This will apply the view in the current window to all folder views.

VMDisk

The purpose is to create a disk to keep contents shared across the VMs Following the instructions at http://www.vmware.com/support/ws45/doc/ws40_disks.html#1046465 Find your VM installation and run the following C:\Program Files\VMware\VMware Workstation> vmware-vdiskmanager.exe  -s 10GB -a ide -t 1 -c "D:\Virtual Machines\vmDisk.vmdk" (s: size, a: interface, t: type (0-3 for increase and size options), c:create) Creating disk 'D:\Virtual Machines\vmDisk.vmdk'   Virtual disk creation successful. How to browse a Vmdk? http://www.vmware.com/support/ws45/doc/disks_add_ws.html#1008949 Tried to add this newly created disk when the vm server was on by going to settings/add/hard drive/existing virtual. Got error: failed to add disk ide0:1 I shutdown the vm pc and add disk then try starting the machine. Then went to disk mgt in windows where I got the "Initialize Disk" prompt New Volume > Simple > Quick format and voila!!

Big Data & Hadoop

Since everything moves fast in the IT world, you have new terminologies entering their 3rd or 4th generation by the time you get a chance to get your hands dirty with them. Big Data has been one of them, an alluring technology allowing massive distributed power over large datasets using the famous map-reduce algorithm. Apache Hadoop allows scaling to massive proportions and has been in use with tech giants like Google and Facebook. I decided to start running a Hadoop cluster myself using the following guide as a started. https://github.com/GoogleCloudPlatform/solutions-google-compute-engine-cluster-for-hadoop/blob/master/README.md This version installs Hadoop locally but uses the Google App Engine and Google Cloud Storage  and allows basic scaling/clustering. I started running the pre-requisites on a VM Centos 6.4 and things were going ok. Then I realized that I needed to go deeper into Hadoop and maybe run a sample locally, without achieving the Cloud version first. ...
