Microsoft has released for download Hyper-V version of Windows Server 2008, this component will allow IT users to run different virtual machines on one physical machine without the need of running a full Host OS.
With server virtulization you can cosolidate work loads of underutilized machines onto smaller number of servers reducing energy and hardware costs and maximizing performance of all your servers.
Other beneifts with virtualization is the ability to take snapshots of a running machine wich can then be easily revert to a previous state improving the overall recoverability your Virtual Machines. The ability to easily test upgrades and service packs prior to upgrading the production machines without the need of purchasing new hardware. Migrating Virtual MAchines from one physical host to another with minimal downtime.
Alan Stevens from ZdnetÂ has written an excellent article on the topic of Hyper-Vï¿½

With more and more companies outsourcing work abroad or even having their work force located around the globe and many roaming users that want access to their full system as if they where in the office.
IT professionals or facing huge challenge in maintaining client’s desktops and backing up all this dispersed data. For example you are a software company that has just been awarded a new project and you need 10 more developers, these developers needed to run Visual Studio, WebSphere, Full MSSQL and other office applications.
We all know how hard it is to source developers based in one location but if you recruited developers from around the world your task would be much easier other than the fact that you would need to purchase, install and maintain these desktops. The cost of buying the equipment would be high given that once the project is finished it would be difficult to return the machines back to base.
Other solutions would be setting up Citrix Presentation Server Infrastructure which is far too expensive or the VMARE VDI Approach which uses too many system resources for memory storage and CPU.
I recently came across software that would certainly fit the bill for the above solution.
By using Virtuozzo’s virtual desktops you are able to install windows 2003 deploy virtual desktops which are connected via IP using remote desktop you can change the look and feel of the OS to behave just like a desktop.
The foot print of each Virtual Desktop is so small in comparison to VMware as only one host OS is installed and furthermore you are able to share the full resources of the Server between all Virtual Servers e.g. if you installed Virtuozzo on a Quad Core Server with 16 GB of ram each user could use up to 16 GB of ram depending how much other Virtual desktops where using so you could end up with a virtual desktop that is much faster than your local machine.
Management of the virtual desktops is more simplified as you only have one host to manage and deploying different software in each Virtual Desktop is as simple as ticking the package you want each use to have.
This is still a new concept and not widely used but that was the same for server virtualization just 5 years ago not many companies used this technology and know it’s one of the most talked about topics.
There are still several drawbacks that need to be resolved for this to hit the mainstream and become more widely used.
- Firstly thin clients are still to expensive (Most users would be using the personal machine anyway)
- The graphics for multimedia users leave a lot to desire
So for any business that find themselves in a similar situation this is a would be a worth considering as the initial investment is very low compared to other options.
This the latest news in Virtuozzo’s Efforts to make VDI a reality

Recently there has been a lot of talk about what software designers should use, or whether they should just skip the entire process and go straight to HTML & CSS.Â The debate continues, butÂ I want to echo some of the responses made and emphasise that design software in any form is just a tool, and that which tool you use hugely depends on what you are trying to achieve.
We have a huge variety of clients and design needs here at Datadial.Â Over the last month I have used Photoshop, Visio, the good ol’ fashioned pen and paper and in one case I did go straight to HTML/CSS.Â What method do I like to use?Â It all depends on the client’s needs!Â The project that I went straight to HTML with had a very minimalistic layout that is hugely dependant on typography.Â The ones I use pen & paper on require a large level of creativity and speed that you cannot get from going straight to a computer.Â Photoshop is very flexible and creative, likewise for Illustrator.
I don’t think the tool really matters either. As long as the end result is what the client is after and works for their audience, then whether or not you use Photoshop doesn’t come into the equation.Â The tool is not going to make a successful website – that comes to understanding who is using the site and designing for them.

My bookmarks toolbar in Firefox is full with great websites at my fingertips to keep up to date with what is happening in the web design industry.Â I have recently moved to London from New Zealand and I accidently left my great list of resources behind – whoops! I really should get into online bookmarking!
So I’ve had to rebuild my bookmark collection and thought it would be nice to share some them with you here (in no particular order…)
- Web Designer Wall – perhaps my favourite website of all, the mixture of news, tutorials and resources is just spot-on!Â And the site looks so pretty
Spoon Graphics and Design Reviver are in a similar vein with that magic combination of content.
- Best Web Gallery is a great spot for research and inspration.Â I really like it how this gallery doesn’t discrimate about the technology used on the featured site, like there are Flash sites mixed in with Web Standards sites – but they are all chosen because of their outstanding design.
- A List Apart – the authority and cutting edge on web standards developments.Â Publishing techniques like the Faux Absolute Positioning is just invaluable, and illustrations are just so gorgeous…
- Which brings me to illustration websites.Â Unfortunately most of the great illustration sites I used to have bookmarked were ones I’d stumbled upon by accident, but Keven Cornell’s site is a superb website that inspires me before I even read a word!
- Signal vs. Noise is a must read for anyone in the web world.Â Likewise for other blogs by the industry leading guys such as Douglas Bowman, Jeff Croft, Mark Boulton and John Hicks.Â I still miss Andy Clarke’s old blog, but keep an eye out for the occassional post at Stuff & Nonsense
- Design Float is a great website that collates other blog posts about web design.
- Other design resources like ColourLovers (perfect for fleshing out colour schemes), Photoshop brushes, free fonts and more tutorials.
- Viget Inspire is a great blog by the web designers at Viget, addressing many issues regarding web design.
- And last but by no means least is the Web Standards Group email list.Â Over the last year or so I’ve found that the list itself can be rather tedious at times, but then once a week Russ Weakley puts out the Links for Light Reading which is a summary of what’s going on around the blogosphere and in the web design/standards world.

With Sainsburys website going down this week and Amazon’s the weekÂ before it is worth taking a moment or two to consider what would happen to your business if your website was out of action.
For most e-commerce clients this could have catastrophic consequences: not only would sales evaporate but you would also lose access to all your salesÂ and customer data.
However, hosting and the quality thereof is often totally ignored in client briefs.Â It is definitely not a priority and is only ever occasionally paid lip service.Â This may have been ok a few years ago when websites were just an experiment and an addition to an existing business rather than the core to a business.
However, it is difficult to convince people to invest in proper corporate hosting as there is aÂ perception that hosting should be practically free. It’sÂ true there areÂ some companies offering hosting for Â£10 per year of less.Â Honestly, what do you think theseÂ companies would provide in terms of back up or reliability servcie lever agreement.Â Not much I think.
So what should you consider when hosting your website.Â Â There are many things to consider, here are just three.
First, where is your website being hosted and who manages and owns the servers.Â Most websites in the UK are hosted in Telehouse in Docklands where there are massive generally well managed datacenters.Â But have you ever seen inside a data center, have you ever asked about their air conditioning systems, their own back up power supply, their connectivity to the web?Â Then what about the servers; who owns them? Who is responsible for updating them with critical patches? When is this done?Â What happens if they crash? What is the rebuild time? How many other sites are their on the same server as yours? How secure is the access to the servers?Â If you are not asking these questions then you are not taking your website presence seriously.
Second there are back ups.Â How often is your site backed up and where are the back upsÂ kept? If your service provider’s data center is blown up (a very realistic proposition, especially if you house your website in Telehouse in docklands) will the back ups go up with it.Â Â If they are kept offsite how often are they taken offsite.
Third, what aboutÂ redundancy.Â Â If your server crashes is there a mirror server which will automatically take over?Â What if your website is overloaded with visitors, can your server handle the traffic?Â Is there a load balancing mechanism that will automatically divert users to an alternative server?
All these issues need to be addressed when considering hosting and website owners need to change their mindset from considering hosting as essentially a free service to one that is valued and is invested in appropriately according to business requirements and risk assessment.

Disclaimers and signatures in general are very easy and quick to implement. Saying that if you are a small business running exchange 5.5 2000/2003/2007 and need to ensure that all users are setup with a standard Disclaimer and Signature or other advanced features you would normally need to use a third party software.
There is no better product than Exclaimer to achieve the desired results. In the Scenario where a client with over 50 users needed to add a disclaimer, Signature and auto-reply (to certain groups) with different responses. My only request to the client was send me a list of all user details and request all users to remove signatures before they leave at the end of the day.
An hour later after updating there Active Directory with staff details I was able to setup a centralised location for all Signatures and Disclaimers.
All user’s information is pulled in automatically from the active directory, and groups where setup with different auto-responses.

Just how popular is Vista today? How many people have switched from IE6 to IE7? Just what share of the browser market does Firefox have?
For answers to these questions and more it is worth regularly checking W3 Counter’s Global Stats which can be found here:
These stats are generated by tracking the last 32 million unique visits to 5,500 websites that represent a broad cross section of internet traffic. From each unique visit, the web browser, operating system, country of origin and screen resolution can all be determined to produce a reasonably good picture of just what general web traffic looks like today.
From looking at the latest stats for 20/08/07 we can see that a person in the USA, running Windows XP, Internet Explorer 6 with a screen resolution of 1024×768 is your average Joe web surfer, this accounts for 6% of web users. Myself I am based in the UK, running Windows XP, Internet Explorer 7 (as my primary browser) and screen resolution of 1280×1024. Only one in a thousand computers run the same combination as I do.
But lets look at the really interesting stats.
Starting with web browsers we can see that Microsoft’s Internet Explorer still dominates the market with an approx 66% share. This is not taking into account the stats for IE5, IE4 and earlier, which I am sure some systems in less developed countries are still running. However the real story here is that IE’s lead is slipping due to Firefox’s continuing popularity – Firefox versions 1.0, 1.5 and 2.0 now account for approx 25% of all web browsers. Safari still has an approximate 2-3% share, however it is unclear whether Safari or Firefox dominate the browser industry for Macs.
Operating system stats show that it’s been a slow start for the brand new operating system from Microsoft – Windows Vista. Just 3.33% of the OS market in August, but recent trends show that share increasing. In May 2007 it was 2.13% and has increased by 1.2% over the past 3 months. XP still dominates, but I expect to see Vista’s share increase more rapidly over the next few years as more people buy new PCs or upgrade. Mac OS X users still account for just under 4% of all users suggesting that the marketing managers at Apple need to do more than their latest “Mac vs PC” advertising campaign to encourage more people to make the big switch.
The stats for the countries of origin offer no real suprises with the US of A leading. Germany and the UK in 2nd and 3rd place respectively and a suprising Latvia in 4th. The Chinese account for just over 2% of all users who visited the web pages in question, but recent media reports suggest this statistic is far higher (almost as dominant as the US). It is well known that the Chinese government have blocked internet sites, which could include many in these reports, or that it may be that the sites in the report are more westernised, located in the US (may be blocked), or are written in languages that Chinese web users are generally unlikely to understand – you can only speculate.
Screen resolution statistics are largely trivial, but the most common is 1024×768, which I am sure will remain dominant for many years to come. Many IT professionals, gamers and experienced computer users generally opt for higher resolutions such as 1280×1024, or widescreen resolutions such as 1280×800 or 1440×900. If any of these statistics should be taken into consideration its that 8.42% of web users are still using a low resolution of 800×600. This figure is falling slowly, in May 2007 it was 9%. While many of the systems running 800×600 may be in less developed countries, nevertheless it is important for web designers to design websites with this low resolution in mind. An example of how not to do it – http://www.hrodc.com/.
Because of the lack of legacy data, it is difficult to put some of these stats into context over the past few years, but rest assured I will be keeping track of them over time and a review of the stats will come in the shape of another blog article towards the end of the year.

If you are like me where you have to give support on several different systems and are constantly hopping desks looking for a free mac or linux, or you have several machines in front of you and you are having to switch between machines using a kvm switch you are going to love this tool synergy.
I lined up 4 Desktops and monitors with different OS that I constantly use. I then installed synergy on all machines, after 15 mins I was in control of all machines using only one mouse and keyboard and Scrolling typing and opening programs from left to right across all desktops as if the computers where welded together
Matt Cutts shows how to configure Synergy in six steps
