Microsoft Software Evaluations – Windows 7 & 8.1

Due to Windows 7 no longer being the most recent version of Windows it is no longer listed on the TechNet link shown in Exam 70-680 Configuring Windows 7 Self-Paced Training Kit: This link only has downloads for Windows 8.1 Enterprise Evaluation and Windows Server 2012 R2.

If you need free evaluation copies of Windows 7 Enterprise or Windows Server 2008 R2 for practising for Microsoft exams they can be found here:

Windows 7 PE – ImageX Error Opening File

Whilst working through Exercise 2 of Chapter 2 – Configuring System Images in MCTS Self-Paced Training Kit (Exam 70-680): Configuring Windows I got the following error when trying to use ImageX on the Windows PE disc I created.

Error opening file:[d:\images\myimage.wim]
The system cannot find the path specified

This was caused by the folder “images” not existing on the drive the image was being written to. To fix this, the below command needs to be run before using imagex.exe to create your image in step 4.

mkdir d:\images

Once you have run this continue through the steps and you should find the image is created with no errors.

Windows 7 PE – Boot selection failed

I am currently working through the MCTS Self-Paced Training Kit (Exam 70-680): Configuring Windows book but got stuck on exercise 1 in Chapter 2 – Configuring System Images due to the book missing out a step.

After running through the exercise then booting from the Windows 7 PE disc I got the following error in the Windows Boot Manager:

Windows failed to start. A recent hardware or software change might be the cause.
Status: 0xc000000f
Info: The boot selection failed because a required device is inaccessible.

This is caused due to the not including winpe.wim which needs to be added to your sources folder and renamed to boot.wim before you create the ISO. Once you have completed step 6, run the following command:

copy c:\winpe\winpe.wim C:\winpe\iso\sources\boot.wim

Once this command has run, continue through the steps and you should find Windows PE will now boot correctly.

WordPress Subdirectoy Move Issues

I recently moved my WordPress install into a subdirectory so I could clean up my root directory.

To do this I backed up my website and database then followed these instructions from WordPress: Giving WordPress Its Own Directory – Moving a Root install to its own directory.

This all worked perfectly until I viewed one of my blog posts which was meant to have images. All my images (or anything else that was stored in wp-content/uploads/ was now missing because the address had not updated to my new subdirectory. The reason for this was all my links were hard coded into my posts and not merge fields.

To fix the issue I used the Search and Replace plugin by Inpsyde. Using this tool I searched for /wp-content/uploads/ in the _posts table and replaced it with /{new_directory}/wp-content/uploads/. This worked perfectly and my images are now all working perfectly again!

Install From Unidentified Developer – Apple OS X Mountain Lion Gatekeeper

I installed Apple OS X Mountain Lion (10.8) Gold Master on my MacBook Pro yesterday, only to find out it would not let me install the software that I wanted to. This was due to a new feature called Gatekeeper. This software aims to protect your Mac by only allowing you to install software from the Apple App Store and Apple Identified Developers. I can see how to this feature could be good for computer illiterate people so they can’t mistakenly install something bad, but for anyone that knows even the simplest thing about computers they generally know what to install and what not to.

As you can see from the image above I was trying to install Microsoft Messenger, which is not going to damage my laptop, as Microsoft is a very well known developer and I downloaded it from their website. Even still Gatekeeper would not let me install it or tell me how to turn it off so I could do what I wanted with my own laptop. I did manage to find out how change it to allow me to install any software, instructions on how to do this can be found below.

The OS X File Quarantine (the pop up that appears telling you a file was downloaded from the internet) is a great feature, and as it has included a Malware checker since Snow Leopard it is plenty of protection. Gatekeeper is going to far and it won’t be long until just like with iOS you will only be able to install apps on to a Mac from the App store, meaning Apple will get to completely filter what you can and can’t run.

How you can turn off Gatekeeper:

  1. Go to System Preferences
  2. Open up Security and Privacy
  3. In “Allow applications downloaded from:” change it “Anywhere”

You can now enjoy any software you wish to install on your computer!

Apple OS X Messages Beta Download Link

Having used Apple Messages Beta since February, I got worried when I reinstalled Lion and found that the download link was no longer on the Apple site.
I use Messages a lot to chat with friends that have iPhones, something you can’t do with iChat.
After doing some searching I did find out that Apple still have the Beta hosted on their site, you just need a direct download link to get hold of it. So here is the direct download link for Apple OS X Messages Beta

How To Solve Alan Turing’s Google Doodle

“Alan Mathison Turing, OBE, FRS, was a British mathematician, logician, cryptanalyst and computer scientist. He was highly influential in the development of computer science, providing a formalisation of the concepts of “algorithm” and “computation” with the Turing machine, which played a significant role in the creation of the modern computer.”  Source: Wikipedia.

Leonardo da Vinci’s 553rd Birthday Google Doodle

Today would be Alan Turing’s 100th birthday, so to celebrate Google have made one of their famous Google Doodles(Click the link to view the archive of Doodles). Most of their doodles consist of a simple piece of art work in the style of the artist/scientist whose birthday or work it is celebrating fitted around the Google Logo. There are a few interactive Doodles, but all fairly simple, things like a flash based synth for Robert Moog’s birthday or a modified playable version of pacman that fits around the Google logo.

Turing’s 100th Birthday Doodle

For Turing’s birthday they have created a Turing Machine, this is a computer that manipulates symbols on a strip of tape according to a table of rules. The aim is to make the Google logo light up, to do this you must input the binary code for each letter using the Machine. For anyone but the ultimate computer science geek this is an impossible task so here the binary you need to solve the puzzle and a video on how to do it:

G: 01011
o: 00011
o: 00011
g: 01011
l: 01001
e: 10000

Turn Off Raspberry Pi Screen Underscan/Overscan

After installing Debian Squeeze on my SD card and booting my Pi for the first time I noticed that there was a big black border around the edge of the screen. After loading the GUI I tried changing the monitor settings only to see it was locked at 1024×984 pixels, even though both the rPi and my monitor can produce 1920×1080. After reading a lot of forum posts and various websites I found out the reason for it was underscan was turned on so that TVs didn’t cut off the edges.

Here is how to turn off the underscan setting:
1. Open terminal and type:
sudo nano /boot/config.txt
2. Add the following line to the text file:
3. Save the file (Control+O)
4. Exit, reboot and enjoy full 1080p HD Pi

You can also use the file for adjusting the amount of overscan/underscan on each side of the screen. Negative numbers add black bars around the edge, the higher the negative number the smaller the black bar. Positive numbers stop the image spilling off the edge of the screen.



Unfortunately every monitor/TV varies so you have to experiment till you find out which settings work best. Luckily for me just disabling overscan altogether worked perfectly on my monitor (LG W2261VP). I have yet to test it on my TV, but as it is also LG I am hoping disable_overscan=1 will be all it needs.

Raspberry Pi Arrived

I first read about the Raspberry Pi back in December on this BBC News Article: Bare bones Raspberry Pi PC gets ready to launch. It caught my attention as I was wondering how a computer could be made so cheaply and what sort of hardware spec it would be for only $25/$35 (depending on which model you chose).

I was shocked when I read it would have 256MB of RAM, a 700MHz ARM processor and full 1080p HD video. Not far from the spec of the 2nd generation Apple TV (the current model on the rPi release date), it even beats it in video quality as the 2nd gen aTV only goes up to 720p.

On the 29th of Februrary I was up early to order mine, but all I got was over loaded servers as everyone wanted a slice of rPi! I managed to ‘register my interest’ when I arrived home from work that evening (the servers were still very slow though) and finally 3 months later it has arrived in the post.


I chose to buy the $35 Model B board, as it was the first to be released, but also because it has 2 USB ports (the Model A only has 1 USB port) and a built in ethernet port.

Although all you get for $35 is the rPi board (it did also come with a free tshirt from Farnel), I found that I didn’t have to buy anything else to get it up and running like most geeks I already have everything else you need (keyboard, mouse, SD card, micro usb charger and a monitor with HDMI).


My first impression of it was just how tiny it really is, it is a lot smaller than my hand! A the moment I am using and upturned lid from a Ferrero Rocher box as a case for it, but it is far from ideal (and way to big for such a tiny computer) so I am on the look out for something better. Some people over on the rPi Forum have had some great ideas for cases included ones made with Lego and some very professional looking cases made from perspex.

All I have managed to do on it so far though is install an operating system (I chose to start with Debian “squeeze” as it is the recommended OS by the Raspberry Pi Foundation) and turn off the underscan/overscan so that there wasn’t a huge black border around my monitor (this is needed for if you are running your rPi on an old TV which cuts off the edges). Read my tutorial on how to turn it off here: Turn Off Raspberry Pi Screen Underscan/Overscan

I now have a bit more spare time though so should be able to start to using it and learning to program!
