Microsoft in the Post PC Era

Many a desktop user has complained about Microsofts Windows 8 operating system migrating to a user interface more suitable to a smartphone or tablet. They do not see the big picture.
If you are old enough to remember the days before the internet, the personal computer was a tool for work and than a gaming device. When the internet became part of our daily lives, computer sales took off. One day, everyone would have a personal computer. This is still true today, but the definition of what is a personal computer has changed.
For some people, a smartphone alone will be enough to meet their personal computing needs. Others, finding a smartphone insufficient, would select or add a tablet to their stable of devices. Desktops and laptops will eventually be relegated to their status of prior to the advent of the Internet age: machines for work.
IDC estimates that this year tablets will outsell traditional desktops. By the end of 2014, tablet sales will surpass laptop sales. Nearly three smartphones are sold today, per desktop of laptop sold. All this means, is in two years time, desktops and laptops will make up just about one in every five computers sold.
In what has been dubbed as the Post-PC era, you find Microsoft which once held a 90% share in personal computers, now looking at holding a 90% share in one in five personal computers sold within two years tie. That is really just an 18% share of all personal computers. Holding on to that 18% share is going to be harder in the Post-PC era.
Microsofts stranglehold on the personal computer market, was secured by the fact that is was the center of application development. Pretty much all software developed was Windows compatible, with only a fraction of the software developed for Windows also being released for Mac OS and Linux. If you wanted a computer that could run your work related applications, and your entertainment applications, a Windows computer was the ultimate jack-of-all-trades.
This is the raison dĂȘtre for Windows 8 is to maintain this status. With Windows Phone 8, Windows RT and Windows 8, Microsoft is hoping to get a substantial share of the smartphone and tablet market. the segment which will soon comprise four in every five computers sold. With a substantial share of the smartphone and tablet market, apps would be created for Windows Phones and Windows Tablets, could be easily ported for Windows desktops and laptops.
If Microsoft is unable to break into the smartphone and tablet market, it will find itself holding on to the lions share of the traditional desktop market, but stagnating app development for desktops in general would further threaten its postion. The app ecosystem that has made Windows dominant for so long, would cease to exist.
As the traditional personal computer retreats to becoming a work device, consumer software development will focus on Apples iOS and Google Android. Less and less consumer software will be developed for desktops. In this environment, operating systems like Mac OS, Chrome OS and the various Linux distributions will find it easier to compete with Windows. When desktops and laptops are no longer expected to be multi-faceted devices but rather dedicated business machines, it is of little importance whether or not you laptop can run Starcraft III.
Those claiming that Windows 8 tablet centric interface will be the death of Windows on the traditional desktop are missing the point. The failure of Windows Phone and Windows 8 on the tablet is what would sound the death knell for Microsofts desktop operating system.

Are You Ready To Drown Your PC in Oil

You know how hot your laptop can get when you use it for hours? Imagine how hot servers —the high-powered computers that run websites and apps— must get... Now imagine a whole building full of servers running at full tilt—and grab some ice water.
Keeping data centers cool is a major engineering problem, not to mention an ecological one. Intel is working on a new approach: submerging them in oil.
Intel just concluded a year-long test of the tech with immersion-equipment company Green Revolution Cooling. It has declared that its chips are ready for the dunked-in-oil technique, reports Rich Miller at Data Center Knowledge.
Today, data centers use air cooling. This means things like building bigger buildings, so servers can be spread out, plus limiting the number of servers in each building, If liquid cooling works—as Intels tests show it does—this means that existing buildings can house more computers and each one can run more workloads.

Plus, submerged computers may be more powerful because faster CPUs usually require more power which produces more heat.
The liquid involved is mineral oil which reduces heat like water, but doesnt conduct electricity.
Submerged desktop PCs have actually been around for years. Below Ive posted a video that shows one being built in 2007. And some old-school supercomputers used liquid refrigerants. But submerged high-performance computers running in a data center are new and could be a fantastic alternative as the world moves to cloud computing.

Cloud computing is where applications are run in a data center and accessed from a PC, mobile phone or tablet. The cloud requires lots of servers in lots of data centers. This could be a great new way to cool them.
The major advantage of mineral oil cooling is that it is relatively cheap and can be adapted to work with a variety of systems ranging from small computers to massive servers. Since it is non-conductive, the oil doesnt short out circuits and is harmless to computer hardware. On the other hand, it can be very difficult or almost impossible to clean and remove mineral oil from the hardware once it has been submerged.
The cooling alternative is definitely appealing to massive server arrays, saving precious energy and cooling costs. The only downside is that the oil needs to be flushed and changed every ten years or so.
