On viewing the Console in OS X I discovered I was getting lots of CalendarAgent errors:
CalendarAgent: AOSKit ERROR: (-) RAF: Invalid url -- https://<username>%email@example.com/calendar/dav/<username>%40gmail.com/
It turns out that a bug in the Mail, Contacts & Calendars section of System Preferences causes a Google Calendar to be misconfigured.

The Punnet is a cardboard case for the Raspberry Pi that you can print yourself from the PDF and cut out. You can print to paper and then glue that onto card if your printer isn’t really up to it.

Adding an additional SSD to OS X and retaining the original HDD in a MacBook Pro.
By adding a small SSD to OS X congaing the Operating System and Applications an increase in performance can be achieved. Boot times can drop by as much as 50% when compared with a standard 5400 RPM HDD as fitted to a MacBook Pro.
A 64GB SSD can hold OS X Mountain Lion and a reasonable sized Applications folder. However, it is not a suitable size to hold much user data in terms of photos, music and films. Retaining the internal HDD of 750GB allows all that information to be stored on the slower but larger volume. A MacBook Pro with an SSD and HDD performs much like the new Apple Fusion Drive but without the dynamic data tiering. Moving the OS X Users folder to the SSD from the HDD may be required due to space constraints.
Clone the HDD to the SSD and then use the old User folder on the HDD.
Elements that broke during this process:
Steam – SSD had been formatted as Journaled Case Sensitive HFS+ which breaks Steam

Windows Blue – or possibly Windows 8.1 is rumoured for release this summer. Rather than as just a Service Pack though, it has been suggested that this will be the beginning of an annual upgrade plan for Windows.

The latest update to OS X Mountain Lion v.10.8.3 now supports Boot Camp running Microsoft Windows 8. Boot Camp 5.0 now supports Windows 8 officially. Previously a Mac could run Windows 8 in Boot Camp using the Windows 7 drivers but without Apple support. Boot Camp 4 supported only Windows 7 but in 32-bit and 64-bit variants. Boot Camp 5 supports both Windows 7 and Windows 8 but only in the 64-bit variant.

My first 15-inch Macbook Pro (Late 2007) has just turned 5 years old. To celebrate, the Apple Li-ion battery A1175 (Apple part: MA348LL/A), which was already a replacement for the original, has decided to die. This means that the A1175 battery is giving up fairly consistently after about 30 months (based on a sample of 2) as the first A1175 battery that came with the laptop had a similar untimely demise.
The batteries from Apple for replacement are an eye watering £101! This put battery costs at £40 for official batteries. Thankfully there appears to be some reasonable Chinese alternatives which can be bought on Amazon for around £20.

High Efficiency Video Coding (HEVC) also known as H.265 is set to enable the future TV resolutions of 4K and 8K (also known as Ultra HD).
In the shorter term however it will allow the delivery of HD TV with about half the bandwidth of H.264 used for Blu-Ray and Internet streaming. Apple’s 2012 iPads already support HEVC with possible support of Apple TV to follow.

Apple does not officially support Microsoft Windows 8 with the Bootcamp dual-boot software available for Apple Macintosh computers. Currently Mountain Lion only has driver support some Microsoft Windows 7.
Several people have reported that there are few differences between Windows 7 and Windows 8′s device driver requirements (adding weight to the view that Windows 8 is mainly a user interface upgrade). Therefore if you have Windows 7 running in Bootcamp it shouldn’t be too difficult getting Windows 8 work either.
Microsoft have recently confirmed that they are putting the price of Windows 8 up considerable at the end of January 2013, so the time to upgrade is now!
With Windows 7 Home Premium (64-bit edition) already installed on my MacBook Pro (Early 2011) I purchased the Windows 8 Pro (64-bit edition) as a download only for the current price of £24.99.
The main issues experienced with the MacBook Pro on initial install were related to device driver problems. This simplest to solve was a problem with the screen brightness. This appear to be cause by the adaptive screen brightness settings not working. Next the MBP Touchpad not working in Windows 8 can be solved using a re-install of the already present Bootcamp drivers.
Connecting a second display via HDMI, the Samsung Syncmaster P2470LHD to the MacBook Pro with an ATI graphics chipset produced the same black-border underscan issue as with Windows 7 on Bootcamp. A work around can be found by adding a DigitalHDTVDefaultUnderscan DWORD to the ATI settings in the Windows 8 Registry with RegEdit.

The Wintec filemate 64GB ExpressCard is a Solid State Drive (SSD) which will fit into the ExpressCard 34 (34mm) slot on the Early 2011 17-inch MacBook Pro. The card adds 19.6g to the weight of the laptop but allows the OS X system files and a reasonable sized Applications folder to sit on the SSD while retaining the User folder on the internal Toshiba HDD.
Xbench shows the difference in benchmark results which on paper is 3 times the performance. However, looking at the detail the major change is the Random Uncached Write and Read for 4K blocks which in the HDD are a cripplingly slow 1.36 MB/s and 0.41 MB/s respectively. This increases to 21.05 MB/s and 9.78 MB/s on the SSD for Write and Read respectively which relate to 15.5 times and 23.9 times performance increase.
Original Apple fit 750GB Toshiba MK7559GSXF HDD at 5400rpm
New Wintec 64GB ExpressCard SSD
Real world experience is a boot time which drops from around 2 minutes for a fully working desktop on the Toshiba HDD to 1 minute when using the Wintec 64GB SSD.
The Wintec filemate 64GB ExpressCard SSD does not support the TRIM function.
