Unprotected computing practices

The news that many medical computing systems are infected with malware doesn’t suprise those working in the field

A US study finding malware is rampant on medical equipment shouldn’t come as a surprise to those running industrial computer systems in their businesses.

It’s notoriously difficult to update medical equipment or other sensitive systems as a security patch could have unintended consequences. Unlike a home or business computer, these patches have to be thoroughly tested beyond the precautions vendors take.

So it isn’t surprising that these systems aren’t kept up to date although some equipment suppliers are more tardy than they should be in updating the servers they supply.

A few years ago I came across CCTV systems running on the original version of Windows 2000 which were hopelessly compromised. This is an unacceptable situation for the customer and was more the result of vendor carelessness than any concern that customers could be affected by these unsecured machines.

Not having the latest software patches creates a weakness in any computer device as most common way viruses find their way onto networks is through systems not being updated – Australia’s Defense Signals Directorate rates unpatched systems as being the number one cause of corporate security breaches.

This is what caught out the Iranian nuclear program with the Stuxnet worm as the Siemens SCADA devices used by the Iranians were running older, unpatched versions of Windows. The designers of Stuxnet took advantage of a number of known weaknesses in the software and were able to damage the equipment being controlled by the systems.

Obviously systems should be patched wherever they can be and there’s no excuse for not patching most office and home computers. It’s also worthwhile carrying out a number of other security steps to ensure an infected computer can’t damage your network or catch a virus through your Internet connection.

The survey looking at these medical systems is a good wake up call to all of us that we need to take computer security seriously in our businesses.

Meeting the solid state Woz

The fast talking Steve Wozniak surfs into town on a wave of enthusiasm.

When the opportunity comes to meet co-founder of Apple computer Steve Wozniak you jump at it, despite being jet lagged from the previous day’s flight.

One of the tough things when writing about Steve Wozniak is that he is a fast talker. You have to be quick to keep up with his ideas and words.

Steve was in town to show off the range of solid state computer memory cards manufactured by Fusion-iO, a company based in Salt Lake City.

Wozniak liked the idea so much he became Fusion-iO’s chief scientist in 2009. “When I first saw the iO drive, it was so beautiful I had to buy one from the company and put it in a frame just to frame it at home.”

What enthused Woz were Fusion-iO‘s range of NAND flash memory cards that speed up servers while reducing their power and cooling requirements.

Those power savings are important for data centres when hundreds of thousands of servers might be in one building, Fusion-iO’s CEO and co-founder David Flynn estimates this could save up the industry a $250 billion a year in operating costs.

Probably the biggest benefits though are in the corporate space, one Flynn’s boasts is how one movie studio used Fusion-iO’s products to reduce transcoding between formats from two hours to 39 seconds.

Another case study they show off is how grocery chain Woolworths were able to reduce the 17 hours to run their weekly trading reports to three hours meaning they were able to capture weekend figures for their weekly Monday morning board meetings.

For smaller businesses, the biggest benefit is these products can turn fairly basic desktop computers into workstations with the $2,500 ioFX card promising some serious post production capabilities for a system although one would expect an entry level box wouldn’t have the data connection, hard drive or – most importantly – power supply to cope with the demands of such a device would put on the typical cheap components in a basic desktop system.

All of these changes though are heralding some pretty big changes for big and small businesses.

Where Steve Wozniak sees the greatest application of moving data faster is in Artificial Intelligence applications like voice recognition. Apple’s Siri is a good example of this.

The barrier to effective voice recognition is the sheer amount of data processing required to effectively understand voice commands. Doing this on cloud services is a far more efficient and effective way of doing this.

As we saw at Dreamforce last week, the sheer amount of data pouring into companies is changing how they manage information. Getting access quickly to relevant information is an important part of managing it.

“I’ve never gotten so excited about or fell in love with a technology like this since Apple.” Says Wozniak.

Having a chance to speak to Steve Wozniak up close shows that fast talking enthusiasm is for real. The Woz is a real geek.

Like all true geeks Wozniak is passionate about what he believes in – whether it’s about NAND flash cards or becoming an Australian resident he bubbles with enthusiasm. Just don’t try writing notes down while he’s in full flight.

The risks of tablet pricing

Are Windows tablet manufacturers repeating last decade’s mistakes?

We often forget that tablet computers weren’t invented by Steve Jobs. For a decade before Microsoft and their partners like Toshiba or Dell had been selling ‘slate-like’ devices.

The market wanted tablet computers, particularly business users in sectors like logistics and health care, but the Windows products on offer were heavy, clunky and expensive.

It took the iPad to deliver what the market wanted —  a lightweight, easy to use and reasonably priced tablet computer. This was the reason Apple were so successful.

With Asus’ pricing announcement of their new range of Windows 8 tablets it appears the mistakes made by the PC industry with tablet computers ten years ago are going to be repeated.

The fundamental thing that will kill Windows tablets is cost and these tablets are too expensive compared to the Apple and Android competitors.

While having Windows compatibility and the opportunity to save to USB drives or corporate networks is handy in a tablet, there seems to be little reason for customers not to buy a mid-priced laptop.

It appears though these price points are part of Microsoft’s strategy. Steve Ballmer hinted at this in his Seattle Times interview last weekend.

Q: The iPad has the largest share of the tablet market, but its soft spot, it seems to me, is the price.With the Surface, are you planning to compete with the iPad on price or on features?

A: We haven’t announced pricing. I think we have a very competitive product from the features perspective. …

I think most people would tell you that the iPad is not a superexpensive device. … (When) people offer cheaper, they do less. They look less good, they’re chintzier, they’re cheaper.

If you say to somebody, would you use one of the 7-inch tablets, would somebody ever use a Kindle (Kindle Fire, $199) to do their homework? The answer is no; you never would. It’s just not a good enough product. It doesn’t mean you might not read a book on it….

If you look at the bulk of the PC market, it would run between, say, probably $300 to about $700 or $800. That’s the sweet spot.

The problem is the tablet computer market isn’t the PC market and those price points have changed.

What’s more, the features that attract users to tablet devices or smartphones are different to that of PCs.

Basically PCs, tablets and smartphones are different products.

Applying PC pricing structures, or marketing models, to the tablet market is a risky strategy.

Steve Jobs didn’t do this and Apple succeeded with the iPhone and iPad without damaging their Mac sales, whether Microsoft can pull of a similar achievement with the opposite strategy remains to be seen.

Hands on with Microsoft Office 365 and a Windows 8 tablet

Giving the new version of Office a run on a Windows tablet

One of the key planks of Microsoft meeting the challenge presented by online services like Google Docs is their cloud based Office365.

The success of Office365 is important as Microsoft Office makes up a large chunk of the 24 billion dollars in sales, and $15 billion dollar profit, the company books from its Business Division.

Coupled to this threat is also the move from personal computers to smartphones and tablet devices which Microsoft hope to meet with their Window 8 operating system, Surface tablet computer and Windows Phone.

As part of the Australian TechEd 2012 Conference, Microsoft gave a hands on preview of the Office 365 running on a Windows 8 tablet which was a good opportunity to see how both software packages worked.

Office 365

Office365 is very similar in layout and function to Office 2010 – if you’re using earlier versions of Office, particularly Office 2003, then you may find the ribbon bar and changed menus hard to navigate at first.

Integration with Microsoft’s Skydrive is good and seamless. A nice feature in this is how a user can setup multiple Skydrive accounts as separate drives. How well this works while on the road will have to be tested away from a controlled environment like the one at the TechEd meeting rooms.

The touch screen functions are fairly hard to get used to and they don’t work particularly well with fat fingers which Microsoft attempts to overcome with providing a stylus.

Another complexity is that the menus and touch screen functions aren’t consistent across applications. The handy ‘pinch’ gesture to zoom on Windows 8 doesn’t work on the Office applications on the tablet which is a shame and is also a bit irritating for power users.

Office365 adds a range of other features like web publishing, video editing and IT management tools but the hands on demo didn’t give enough time to properly evaluate these aspects.

Window 8

The first thing that jumps out with Windows 8 is the basic interface isn’t intuitive. The tile based system is difficult to use if you’re used to a keyboard and mouse or mobile systems like Apple iOS and Android.

Another worry is the Windows 8 interface – or “Metro” as it was known – uses different applications to the desktop version. The problem with this was illustrated when trying to run a video on the device as the Internet Explorer in the Windows 8 interface was a different version to that on the desktop so videos would run in one mode, but not on the other.

This confusion between software versions is a recipe for user confusion, lost data and possibly even a security weakness. It’s surprising that having effectively two operating systems running on the device was considered to be a good idea.

Looking under the hood at the Control Panel, the Windows NT heritage of Window 8 becomes apparent. Anybody used to tinkering with the settings on Windows XP, Vista or 7 systems will have no trouble finding their way around the new version.

Overall the performance of Windows 8 was impressive. It’s quite fast and responsive and this is something that Microsoft’s demonstrators are proud of.

Tablet blues

The surprising thing was the Windows 8 system was running on a Samsung tablet with still no ship date for the Windows hardware.

The Windows 8 about screen on a Samsung Tablet

With Christmas approaching, Microsoft are running out of time to compete in the tablet market and it seriously raises questions on whether the Surface tablets were prematurely announced.

The experience with Office365 on the Windows Tablet was satisfactory although the demonstration showed there’s some barriers to adopting tablets as the main work computers.

Office 365 shows the strengths Microsoft have in the market, if Microsoft can get their tablet strategy right then they have a good product to compete with Apple’s iOS and Google’s Android.

Time will tell if they or their hardware partners can get products that customers want onto the market.

Paul travelled to TechEd and stayed at the Gold Coast as a guest of Microsoft Australia.

Microsoft TechEd Australia 2012

Microsoft’s Australian TechEd in 2012 comes at an important time for the software giant.

2012 is the year that will define Microsoft as the market place they have dominated moves to tablet computers and smart phones.

The challenge for Microsoft is how they migrate their desktop and server products to the platforms dominated by Amazon, Google and Apple.

At this year’s TechEd Australian conference the pressure is on Microsoft to present how they will deal with this challenge from tablet computers, mobile phones and cloud computing.

The big ticket item is the Windows phone. After the disastrous launch of the Nokia Lumia 920, Microsoft has to convince the market place they have a viable competitor to the iPhone and the plethora of Google Android devices.

Microsoft have taken the opposite strategy to Apple in trying to offer the same operating system on all their devices. If Windows 8 can run on all systems then they have a chance of locking high margin corporate users onto their platforms.

Windows 8 itself has to have a compelling story to tell. Much of Microsoft’s future relies upon a successful rollout of the new operating system that meets the demands of both consumers and businesses. Users increasingly expect social media and cloud computing services to be integrating into their systems.

Cloud computing is an important part of Microsoft’s corporate strategy and how the new version of Windows Server delivers on the business requirements of using cloud services will be an important factor in the product’s success.

One of Microsoft’s most profitable product lines has been their Office suite of applications. Margins on Office have been under pressure since the release of the free Google Docs suite and the corporate Google Apps product.

The advantage Microsoft have in the office productivity market is their products have the full range of feature business users need and Google, and Apple, have struggled to include these tools in their products.

With new versions of Office, Server, Phone and Windows all being released Microsoft have a lot of stories to tell and the stakes for the software giant are huge. It’s going to be an interesting few days at the Gold Coast Convention Centre.

How much server space do Internet companies need to run their sites?

How much server space do companies like Google, Amazon, YouTube, Hotmail and Facebook need to run their sites?

“How much server space do companies like Google, Amazon, or YouTube, or for that matter Hotmail and Facebook need to run their sites?” is the question I’ve been asked to answer on ABC Radio National Drive this evening.

This isn’t a simple question to answer as the details of data storage are kept secret by most online services.

Figuring out how much data is saved in computer systems is a daunting task in itself and in 2011 scientists estimated there were 295 exabytes stored on the Internet, desktop hard drives, tape backup and other systems in 2007.

An exabyte is the equivalent of 50,000 years worth of DVD video, a typical new computer comes with a terabyte hard drive so one exabyte is the equivalent of a million new computers.

The numbers when looking at this topic are so great that petabytes are probably the best way of measuring data, a thousand of these make up an exabyte. A petabyte is the equivalent to filling up the hard drives of a thousand new computers.

Given cloud computing and data centres have grown exponentially since 2007, it’s possible that number has doubled in the last five years.

In 2009 it was reported Google was planning to have ten million servers and an exabyte of information. It’s almost certain that point has been passed, particularly given the volume of data being uploaded to YouTube which alone has 72 hours worth of video uploaded every minute.

Facebook is struggling with similar growth and it’s reported that the social media service is having to rewrite its database. Last year it was reported Facebook users were uploading six billion photos a month and at the time of the float on the US stock market the company claimed to have over a 100 petabytes of photos and video.

According to one of Microsoft’s blogs, Hotmail has over a billion mailboxes and “hundreds of petabytes of data”.

For Amazon details are harder to find, in June 2012 Amazon’s founder Jeff Bezos announced their S3 cloud storage service was now hosting a billion ‘objects’. If we assume the ‘objects’ – which could be anything from a picture to a database running on Amazon’s service – have an average size of a megabyte then that’s a exabyte of storage.

The amount of storage is only one part of the equation, we have to be able to do something with the data we’ve collected so we also have to look at processing power. This comes down to the number of computer chips or CPUs – Central Processing Units – being used to crunch the information.

Probably the most impressive data cruncher of all is the Google search engine that processes phenomenal amounts of data every time somebody does a search on the web. Google have put together an infographic that illustrates how they manage to answer over a billion queries a day in an average time of less than quarter of a second.

Google is reported to own 2% of the world’s servers and they are very secretive about the numbers, estimates based on power usage in 2011 put the number of servers the company uses at around 900,000. Given Google invests about 2.5 billion US dollars a year on new data centres, it’s safe to say they have probably passed the one million mark.

How much electricity all of this equipment uses is a valid question. According to Jonathan Koomey of Stanford University, US data centres use around 2% of the nation’s power supply and globally these facilities use around 1.5%.

The numbers involved in answering the question of how much data is stored by web services are mind boggling and they are growing exponentially. One of the problems with researching a topic like this is how quickly the source data becomes outdated.

It’s easy to overlook the complexity and size of the technologies that run social media, cloud computing or web searches. Asking questions on how these services work is essential to understanding the things we now take for granted.

Windows 8 to launch on October 26

The next version of Windows gets a release date.

It’s official, Windows 8 has an October 6, 2012 release date.

For Microsoft, the pressure is now on. Not only does the desktop version have to be shipped but also the smartphone and tablet versions. Their cloud services are going to have to be flawless on the day Windows 8 goes live.

The tablet version is doubly important as Microsoft has to convince cynics like me that the Microsoft Surface is not vapourware. With the Surface RT scheduled for release with Windows 8, Microsoft are going to have to announcing pricing and final specifications very soon. Reports are that the Surface is beginning to appear on Amazon sites so release may not be far away.

Nokia too will now be under a lot of pressure as releasing credible Windows 8 are the only hope for the company’s future. As it is, the current range of Lumia phones are now dead in the water despite massive discounts.

As we’ve previously discussed, Windows 8 is essential to Microsoft’s market position and will define their future – a failure will almost certainly lock the once dominant software giant to a another lost decade.

We’ll see a lot advertising and PR hype around Windows over the next few months, the real test will come at the end of October and with the Christmas buying season.

By the middle of next year we’ll have a good idea of just how successful Windows 8 will be. Steve Ballmer’s future depends upon it.
