One of my first tasks I wanted to be able to do after getting my Mac was to be able to remotely connect to my servers and a number of other trusted systems for support. I wanted to try a number of options and my first serious attempt was with TeamViewer.
My Laptop is a Mac, my Home-PC is Ubuntu Linux and my wife uses Windows XP. I installed version 7.0 of TeamViewer on each OS and got remote access in no time. Thought of creating a short guide on the subject even though the application is very self intuitive.
So here is the guide to getting remote access across different Operating Systems using TeamViewer: TeamViewer Guide
One of the first problems I encountered on my Mac was how to manage some external drives using NTFS. After reading a number of blogs, postings and articles I found the one by Sergey Vasilyev to be the best. The following is a quick guide to getting NTFS read/write support on OSX Lion.
- Tuxera MacFuse 2.2: Download Tuxera MacFuse 2.2 from here and install.
- NTFS-3G: Download NTFS-3G from here and install.
- fuse_wait: Update the fuse_wait script by downloading and installing the setup from here.
Next time you connect a storage device with NTFS you should be able to read/write from/to it.
Do note that there are a number of paid alternatives and a more detailed explanation can be found in the original blog of Sergey Vasilyev at http://blog.nolar.info/ntfs-3g-in-mac-os-x-lion-10-7-with-read-write-support/
A key process in database development is obviously database modelling and the main diagrams used are ERD. A number of notations exist, some particular to evangelised by particular DBMS. Here I am documenting a short course/notes about ERD modelling using the Barker’s notation, which is greatly adopted by Oracle.
As usual here is the link, do feel free to comment!

Being blessed by being Maltese, it was inevitable that a love for the sea would grow. Every Summer I would head off for the sea snorkeling. Then at the age of twenty I started the diving course and four years ago I started taking some underwater photography. My all time favorite was at the very beginning of a dive! We start descending, then for some reason I turn back to check on my buddy, Roberto! Click! A great shot is taken! Judge for yourself and comment!

I was once asked by a fellow colleague if it was possible to have an SQL statement that would not allow employees from being registered to events that occur simultaneously.
Consider a database that stores a list of persons and a list of events. Employees would eventually be registered as event attendees. It is possible that multiple events occur at the same time and therefore it is required that the SQL statement prevent any persons from being registered as attendees of conflicting events. It was required that the solution be all in one SQL statement for some reason whatsoever.
The SQL solution is found attached together with a supporting report! As always all feedback and queries are welcome!
Register employees for non conflicting events
