10,000 People have taken The SLOG’s VCP4 Practice Exam

Who would have thought it!! I only set it up to help me revise for the VMware VCP4 Beta Exam.

3 Months later, it now has over 60 Questions (increasing all the time). I receive emails daily thanking me for helping them prepare for their VCP4 exam.  People as far away as New Zealand are being told to use my Exam’s and Study Notes by VMware instructors.

But the most amazing part was when i checked Google Analytics to see how many people are using it:


I never expected it to be soo popular. As you can see the hits per day are increasing at a steady rate, so i’m going to do my best, to keep adding more resources, to make sure you visitors have a reason to keep coming back.

My Twitter account is Suspended!!

This morning I awoke to two Emails from Twitter titled “Your account has been suspended” (Not quite sure why they felt the need to tell me twice).

Written in the Email was the following;

If you are one of my Followers you will know that earlier on this week someone/something got hold of my username/password for my Twitter account and used it to spam all of the people I follow. As soon as I found out, I changed my password and removed any Twitter apps that could have been used to gain access to my account and since then there has been no more spam.

So why have Twitter done this? I have opened up a Support Ticket with Twitter to try and find out.

Update: Just found out that Duncan over at Yellow-Bricks has also had his Twitter account Suspended.

No sooner had I opened the ticket, the ticket was showing as “Solved”. I checked my account, it was still suspended! So I have re-opened the ticket and I await to hear back.

QR Codes – Contact details with a twist

Whilst looking into making The SLOG available on mobile devices i came across something that i had seen in CSI and also in the magazines of a recent flight. Its called a QR Code (QR = Quick Response).

Hardware Abstraction Layer (HAL)

Whilst reading a VMware document on using SQL inside VMware Virtual Infrastructure i realised that i wasn’t 100% sure on what the Hard Abstraction Layer ( HAL) actually is, so i decided to do some reading up, here is my take on it.

What is the Hardware Abstraction Layer or HAL?

The HAL is a part of an Operation System that talks directly to the machine’s Hardware.

The Windows OS is able to support multiple hardware platforms without having to have different OS versions for each hardware platform thanks to the HAL. During the installation of an OS the HAL is chosen depending on the hardware platform, because of this you are normally unable to remove the HDD from one PC and move it to a PC which has different hardware.

A HAL tip when you are installing VMware VM’s using  Windows Server 2003

Windows 2003 Server unlike Server 2008 doesn’t have the ability to dynamically adjust the HAL to accommodate extra vCPU’s after installation. So if you’re creating a new VM which may possibly need to have an extra vCPU added to it in the future, it is best practice to install the OS on a VM with 2 vCPU’s as this will install the SMP (Symmetric Multiprocessor) HAL rather than the UP (Uniprocessor) HAL. Once your install of 2003 server is complete you can change your VM’s vCPU’s back down to one. You now have the option to add another vCPU whenever its needed.

*If i have misunderstood what the Hardware Abstraction Layer is, please message me direct or leave a comment.

GMail Forgotten Attachments – We’ve all been there, done that

Is this a familiar story?

  • You created a new Email
  • You added the Recipients
  • You added the Subject e.g. HR Spreadsheet
  • You wrote a nice passage telling them you have attached the spreadsheet they requested
  • You hit Send

2 Mins later you get this reply… “Sorry i cant seem to find the attachment.”

General IT Introduction

As The Slog is mostly Virtualisation orientated i have decided to add another Catagory called “General IT“. This is a place where i will post Non Virtualisation specific posts.

I’m also going to use this area to aid my learning. I’m always learning and looking to improve my knowledge, so if there something mentioned in conversation or documentation that i dont understand 100% i will research it and write it up in this section.

All comments on my write ups are gratefully received as I’d rather know when I’m wrong or heading off in the completely wrong direction.

If you subscribe to my Blog and don’t want these posts, please let me know and i will try arrange the feeds to not include these posts. Just drop me an email via my Contact page if this is the case.


ZAR Critcal Data Recovery saved the day

Working in IT you’d think that i would practice what i preach?

“Make sure you back EVERYTHING up!”

Well i do now! Whilst on a trip to a beautiful beach my camera decided to tell me that i had a “Memory Card Error” and i was unable to take anymore photos.

Once we had returned home i put the SD card into the reader and received the message we all dread.

SD Card needs formatting
