Steve Ballmer’s big platform change

Microsoft contemplates big changes as the computer market evolves around portable tablets and smartphones.

All Things D today reports that Microsoft is considering a major restructure to reflect changed computing markets.

One of the big messages from The State Of The Internet report is we are seeing three simultaneous changes to the computer industry – the shift from personal computers to smartphones, tablet computers and wearable systems – and Microsoft is at the centre of these transformations.

One graph, first released by Aysmco and expanded in the Meeker presentation, illustrates how fundamental these shifts are to Microsoft’s business.

Microsoft’s domination of the computer industry was almost total at the beginning of the century and remained so until the iPhone was released in 2007. Then suddenly things changed.

With the success of Android and the iPad, the market shifted dramatically against Microsoft and the WinTel market share is now back to 1985 levels when the Commodore 64 was a credible competitor.

The change that Microsoft faces shouldn’t be understated, although the company’s strengths with products like Office, Azure and Hotmail (or whatever this year’s name for their online mail product is) give the once untouchable incumbent some opportunities, particularly in the cloud.

At the end of Mary Meeker’s presentation at the D11 conference, Walt Mossberg asked her about Microsoft’s view that tablets and smartphones are just new computing platforms. Meeker dismisses that with the observation that the data is clear, the market has shifted to Apple and Google.

“Google and Apple are driving innovation,” says Meeker. “Microsoft is not.”

The numbers aren’t lying for Microsoft. That’s why Steve Ballmer has to move fast and think creatively about the company’s future.

ABC 702 mornings – Storage and your computer

How we deal with the information explosion in the age of Big Data is the topic of today’s 702 Sydney segment with Linda Mottram

This morning on 702 Sydney I’m talking to Linda Mottram on the decidedly unsexy topic of storage – hard drives, cloud computing and the struggle to keep up with ever expanding file sizes of documents, photos and downloads.

It’s an opportunity to revisit the How Much Data Does The Internet Need topic which I covered for Radio National last year, although almost certainly that needs updating.

Earlier this year networking vendor Cisco released its 2013 Virtual Networking Index which forecast global data traffic growing fourteen fold over the next five years.

Those bytes slopping around the internet have to come to rest on someone’s hard drive and this is what’s driving the storage crisis.

Yesterday US business site Venture Beat had an op-ed by an executive from Seagate, the world’s biggest hard drive manufacturer where he discussed the storage challenges with a claim from industry consultants IDC that worldwide computer storage is 2.7 zettabytes.

A zettabyte is a trillion gigabytes, or ten followed by twenty zeros – it’s the equivalent of a billion one terabyte hard drives that are standard on most cheap desktop computers.

Where those hard drives are located is the big challenge, is it on your laptop, smartphone or on a somewhere on a cloud service?

The other big challenge is what do you do with all this information – which is where the Big Data discussion comes in.

While data storage is a mundane topic, it’s a big one that matters. I hope you can tune in.

We’d love to hear your views so join the conversation with your on-air questions, ideas or comments; phone in on 1300 222 702 or post a question on ABC702 Sydney’s Facebook page.

Disrupting the incumbents

Industry incumbents like Nokia and Microsoft are finding their market positions disrupted as Apple, Hauwei and Samsung reinvent the marketplaces.

One of the truisms of modern business is that no incumbent is safe, Microsoft, Nokia and Hauwei are good examples of just how businesses that five years ago dominated their industries are now struggling with changed marketplaces.

In the last two days there’s been a number of stories on how the smartphone and computer markets are changing.

According to the Wall Street Journal’s tech blog, PC manufacturers are hoping Microsoft’s changes to Windows 8 reinvigorates the computer market.

Those hopes are desperate and somewhat touching in the face of a structural shift in the marketplace. These big vendors can wait for the Big White Hope to arrive but really they have only themselves to blame for their constant mis-steps in the tablet and smartphone markets.

Now they are left behind as more nimble competitors like Apple, Samsung and the rising wave of Chinese manufacturers deliver the products consumers want.

All is not lost for Microsoft though as Chinese telecoms giant Hauwei launches a Windows Phone for the US markets which will be available through Walmart.

Hauwei’s launch in the United States is not good news though for another failing incumbent – Nokia.

Nokia’s relationship with Microsoft seems increasingly troubled and the Finnish company is struggling to retain leadership even in the emerging markets which until recently had been the only bright spot in the organisation’s global decline.

Yesterday in India, Nokia launched a $99 smartphone to shore up its failing market position on the subcontinent.

For the three months to March, Nokia had a 23 percent share of mobile phone sales in India, the world’s second-biggest cellular market by customers, Strategy Analytics estimates. Three years ago it controlled more than half the Indian market.

India isn’t the only market where Nokia is threatened – in February Hauwei launched their 4Afrika Windows Phone aimed at phone users in Egypt, Nigeria, Kenya, Ivory Coast, Angola, Morocco and South Africa.

The smartphone market is instructive on how many industries are changing, almost overnight the iPhone changed the cell phone sector and three years later Apple repeated the trick with the iPad, in both cases incumbents like Motorola, Nokia and Microsoft found themselves flat footed.

As barriers are falling with cheaper manufacturing, faster prototyping and more accessible design tools, many other industries are facing the same disruption.

The question for every incumbent should be where the next disruption is coming from.

In fact, we all need to ask that question as those disruptions are changing our own jobs and communities.

Sunset on the laptop market

Does Toshiba’s release of their Kira laptop mark the beginning of the end for portable computing?

Yesterday Toshiba released their Kira laptop computer – a premium device aimed at the ‘aspirational’ market.

The Kira is a fine device with good specs, little weight and an ambitious $2,000 price point. It probably also marks the laptop computer’s decline.

As tablet computers and smartphones become most people’s preferred computer devices, the laptop computer is becoming a niche device and increasingly less relevant to most technology users. The Kira is fighting for the share of a marketplace that has moved on.

Losing the Aspirationals

Unfortunately for Toshiba, those aspirational customers are locked into their Apple iPads and Sumsung smartphones. Laptops are seen as work devices more valued for their portability and cost.

“We have to give our customers a reason to upgrade their computers,” said Mark Whittard, the Managing director of Toshiba Australia.

The problem is computer users have little reason to upgrade, as nice as the Kira is the price point is just too high for customers who’ve been groomed to expect sub – thousand dollar systems and there are few compelling reasons to buy such a device.

Caught in a pricing pincer

Price points are probably the biggest problem for computer manufacturers – one of the reasons for the tablet computer’s success is they delivered an easy to use, portable computer for half the price of a portable computer.

At the same time the rise of netbooks and the rush to dump unwanted Microsoft Vista and Windows 7 stock onto the market groomed customers to expect cheap computers – few computer buyers are interested in spending more than a thousand dollars on a device.

These factors have squeezed the margins of the major manufacturers like Dell, HP and Asus.

Those pressures are going to increase as volumes fall. For much of the 2000s, laptop computers were fast moving consumer goods – pricing and profits were based on moving large numbers of the devices.

As manufacturing volumes fall, those devices are going to lose their economies of scale which will put further pressures on vendors’ margins.

Laptops aren’t going away, they still have a role for power users – particularly for those, like this writer, who need a tactile keyboard and media editing capabilities.

However those feature rich devices with their nice keyboards are going to cost more as parts become more expensive.

For laptop vendors the challenge is to find the profitable market niches and exploit them. In some ways Toshiba probably has a better opportunity than most with its range of premium and gaming portable computers.

Those in the market hoping the happy days of big volumes and good profits will return to the laptop PC market are in for a painful future. It’s something retailers, resellers and vendors need to understand.

Is there a tablet to cure the reality distortion field?

Microsoft founder Bill Gates puts up an argument for Windows 8 tablets. But is he living in a reality distortion field?

It’s hard not to be impressed by the calibre of guests CNBC’s Squawk Box when they’re able to get Warren Buffett and Bill Gates on together for an interview.

During the interview Bill Gates made an interesting assertion about Apple’s iPad, ““A lot of those users are frustrated, they can’t type, they can’t create documents, they don’t have Office there.”

Bill’s undoubtedly right, some iPad users are frustrated by the device’s limitations. However for every irritated iPad user there are a dozen baffled by the lack of a Start button on Windows 8.

The reality distortion field though is strong, “Windows 8 really is revolutionary,” says Bill. “It takes the benefits of the tablet and the benefits of the PC and it’s able to support both of those.”

The Microsoft founder is enthusiastic about the company’s Windows tablet, “you have the portability of the tablet but the richness, in terms of the keyboard and Microsoft Office, of the PC.”

It’s notable Gates mentioned Microsoft Office, particularly given the question was about the cloud. It’s clear one of Microsoft’s priorities is to maintain their strength with productivity applications and move with their customers onto the cloud.

The problem though for Microsoft is that Apple’s iOS and Google’s Android are dominating the cloud focused operating systems, leaving Windows behind.

Making matters worse for Microsoft is it’s clear Windows 8 tablets are never going to catch their competitors. Consulting group Gartner last year predicted the global market for tablet computers will double over the next three years, but Microsoft will capture barely 10% of the sales.

OS	2011	2012	2013	2016
iOS	39,998	72,988	99,553	169,652
Android	17,292	37,878	61,684	137,657
Microsoft	0	4,863	14,547	43,648
QNX	807	2,643	6,036	17,836
Other Operating Systems	1,919	510	637	464
Total Market	60,017	118,883	182,457	369,258

Sitting in a reality distortion field is fine when things are going well and you dominate your world, but Microsoft – despite still being insanely profitable – no longer dominates the markets that made it into one of the world’s leading companies.

The challenge for Bill Gates and Microsoft’s management is adapting to those changes, projecting your own frustrations onto the users of a competitor’s product, isn’t a recipe for success.

Hurtling into the post PC era

The latest computer sales figures are not good for those businesses who depend up personal computers.

Consulting firm IDC quarterly report on PC shipment figures this quarter shows a stunning 14% drop of global computer sales. On those numbers, the PC era is definately over.

Across the board the figures are horrible with double digit declines across the board. Market leader HP reported PC sales had fallen by nearly a quarter yet they retained their market lead as all of their competitors reported similar falls.

What’s also notable is the PC industry’s ultrabook attempt to wean consumers off cheap nebooks has backfired terrible, as the analysts note;

Fading Mini Notebook shipments have taken a big chunk out of the low-end market while tablets and smartphones continue to divert consumer spending.

Instead of buying higher priced ultabooks, consumers have abandoned portable PCs altogether and gone to smartphones or tablet computers.

The PC manufacturers must be rueing how they let the tablet computer market slip through their fingers during the 2000s.

Failing to ship decent tablet computers is symptomatic of a bigger problem for the PC manufacturers – their inability to innovate.

The PC industry is struggling to identify innovations that differentiate PCs from other products and inspire consumers to buy, and instead is meeting significant resistance to changes perceived as cumbersome or costly.

As IDC point out, even if they do introduce new products, consumers are wary that any “innovation” is going to be cumbersome. Basically the PC manufacturers have lost their customers’ trust.

How this affects Dell’s proposed buy out remains to be seen; it’s hard to see how investors would not be concerns at a 10% fall in sales, although Dell was one of the better performers.

For Microsoft, this news should further accelerate their moving products and customers to their cloud and enterprise products. For their Windows division it looks like there are tough times ahead.

The decline of the PC market is itself a study in product and innovation cycles. It could well be that the personal computer is going the way of the fax machine.

For some businesses that will be tragedy, but the market – and the opportunities – move on.

Three screens, one screen

Is Blackberry, Apple or Microsoft right about the way we’ll use computers in the future?

One of the points that came out of Blackberry’s Z10 launch last week was CEO Thorsten Heins’ talking about the company’s ‘one screen’ strategy.

Blackberry sees the smartphone as being the centre of people’s computer usage with them replacing personal computers and tablets as the main computing tool.

This is at odds with the rest of the phone and computer industries who are struggling with managing the three or four devices that most people use.

Apple overcame this by having different operating systems – OS X and iOS – and even then the mobile iOS is subtly forked for the different ways people use tablets versus smartphones.

With Windows 8, Microsoft chose to go the opposite way with an operating system which works on all devices. Sadly it doesn’t seem to have worked.

Blackberry’s strategy is to assume smartphones will be their main communications device. It’s a big bet which doesn’t align with what seems to be experience of most people.

Over the last few years Blackberry’s smartphone market share has collapsed from 40% to 4%, so it’s the time for brave bets although its hard to see that customers will use smartphones instead of PCs or tablets is the right call.

It’s an interesting question though – can you see your smartphone being your main computer?

Smelling digital garbage

Excel spreadsheets lie at the core of business computing, but what happens when they go wrong?

James Kwak writing in the Baseline Scenario blog describes how Excel spreadsheets have an important role in the banking industry and their key role in one of the industry’s most embarrassing recent scandals.

In the early days of the personal computer spreadsheets; it was company accountants and bookkeeping clerks who bought the early PCs into offices to help them do their jobs in the late 1980s .

From the accounts department, desktop computers spread through the businesses world and the PC industry took off.

Over time, Microsoft Excel displaced competitors like Excel 1-2-3 and the earliest spreadsheet of all, VisiCalc, and became the industry standard.

With the widespread adoption of Excel and millions of people creating spreadsheets to help do their jobs came a new set of unique business risks.

The weakness with Excel isn’t with the program itself, it’s that the formulas in many spreadsheets aren’t properly tested and often incorrect data is put into the wrong fields.

In his story Kwak cites the JP Morgan spreadsheets that miscalculated the firms Value-At-Risk (VAR) calculations for synthetic derivatives. The result was the London Whale debacle where traders were allowed to take positions – some would call them bets – exposing the bank to huge potential losses.

It turns out that faulty spreadsheets had a key role as traders cut and paste data between various spreadsheets and the formulas that made the calculations had basic errors.

That a bank would have such slapdash procedures is surprising but not shocking, almost every organisation has a similar setup and it gets worse as a project becomes more complex and bigger numbers become involved. The construction industry is particularly bad for this.

Often, a spreadsheet will show out a bunch of numbers which simply aren’t correct. Someone made a mistake entering some data or one of the formulas has an error.

The business risk lies in not picking up those errors, JP Morgan fell for this and probably every business has, thankfully to less disastrous results.

My own personal experience was with a major construction project in Thailand. One sheet of calculations had been missed and the entire budget for lights – not a trivial amount in a 35 storey five star hotel – hadn’t been included in the contractor’s price.

This confirmed in my mind that most competitive construction tenders are won by the contractor who made the most costly errors in calculating their price. Little has convinced me otherwise since.

In the computer industry there’s a saying that “garbage in equals garbage out” which is true. However if the computer program itself is flawed, then good data becomes garbage.

Excel’s real flaw is that it can make impressive looking garbage that appears credible if it isn’t checked and treated with suspicion. The responsibility lies with us to notice the smell when the computer spits out bad figures.

Will going private save Dell?

Can Dell going private reverse the personal computer manufacturer’s decline?

Now Michael Dell and a team of private equity investors are going ahead with taking the company he founded private, the question is will this make any difference to the technology company.

Turning around Dell is going to be a massive task as the company has lost the advantages that made it the world’s biggest PC manufacturer. At the same time, the industry itself is shrinking as corporate and consumer customers move from personal computers and servers to tablets and cloud services.

The triumph of logistics

Dell’s real success lay in logistics. In the early 1990s the company – along with its competitor Gateway – developed a global just-in-time assembly network which took advantage of cheap Asian suppliers, efficient air courier networks and call centres.

Bringing these together meant Dell and Gateway could deliver a custom made computer to a customer in just over a week without the hassle of holding warehouses of stock, employing sales staff or renting stores.

Price was the ultimate advantage and these companies could undercut competitors with their efficient networks, lack of inventory and no retail overheads.

Losing an advantage

Unfortunately for Dell, competitors caught up and by the early 2000s most PC manufacturers were using similar manufacturing methods and were able to match their price points.

By 2006, HP overtook Dell as the world’s biggest PC manufacturer.

Worse yet, Apple adapted Dell’s logistic systems to corner the high end of the PC market and then expand into consumer devices.

Dell’s reaction was to compete solely on price and to do so they cut component costs and outsourced support to lowest cost providers.

This backfired horribly and the poor quality products coupled with execrable after sales support deeply damaged Dell’s brand with the Dell Hell debacle being the public face of widespread customer unhappiness.

Dell in the post PC world

Making matters worse for Dell is that the market has shifted away from personal computers.

Dell has a tragic track record of diversifying out of the PC markets, all of its attempts to move into consumer electronics with PDAs, smartphones, tablet computers and entertainment devices have been, at best, embarrassing.

Enterprise computing has been more successful but even here Dell has shown little innovation and most of their entries into the corporate markets has been through acquiring specialist companies rather than doing anything different.

Part of this to failure to diversify has been because of Dell’s relationship with Microsoft. The various versions of Windows intended to be used on PDAs and tablet computers turned out to be wholly unsatisfactory and left the market open to Apple with the iPhone and iPad.

Going private

That Microsoft is going to have a financial interest in the privatised Dell is not encouraging for the company’s prospects.

Neither is the continued presence of Michael Dell. His return as the company’s CEO in 2007 has not solved the company’s problems.

It’s difficult to see where the problem was being a public company, Dell’s woes were not because of troublesome board members or activist shareholders.

Going private might allow Michael Dell and his team to experiment without the accountability of quarterly reporting, but that barely seems worth 26 billion dollars.

Dell could surprise us all by reinventing its business and claiming a role in the post-PC world, but right now its hard to see how.

Was the netbook the Trabant or Model T of the computer world?

After only five years the netbook computer comes to an end having being killed by tablet computers and vendor hostility. We will remember these systems as the Model T or Trabant of the PC world?

Taiwanese technology website Digitimes reports Asustek have shipped their last eeePC netbooks, bringing to an end a product that promised to change the computing world when they were first released in 2007.

At the time the eeePC netbook picked up on a number of trends – cheap hardware, the maturity of the open source Linux operating system, affordable wireless access and, most importantly, the accessibility of cloud computing services.

There’d been a pent up demand for usable portable computers for years but Microsoft and their hardware partners consistently released clunky, overpriced tablet computers that simply didn’t deliver on their promises.

For users wanting a cheap, fairly robust portable computer then netbooks were a good choice, at the price you could even risk having one eaten by lions.

Unfortunately for netbook a few things went against the idea.

Customers don’t like Linux

An early blow to the eeePC was that retail users don’t like Linux. Most computer users are happy with Windows and MacOS and weaning them off what they know is a very hard sell.

Sadly on this topic I have first hand knowledge having suffered the pain of co-founding a business in the mid 2000s that tried to sell Linux to small businesses.

Asustek discovered this when they found customers preferred the more expensive Windows XP version over the original Linux equipped devices.

Unfortunately Microsoft’s licenses damaged the economics of the netbook and held the manufacturers hostage to Microsoft who, at the time, wasn’t particularly inclined to encourage customers to use cloud services.

Manufacturer resistance

Microsoft weren’t the only supplier unhappy with netbooks. Harry McCracken at Time Tech describes how chip supplier Intel worked against the products.

For manufacturers, the netbooks were bad news as they crushed margins in an industry already struggling with tiny profits. However all of them couldn’t ignore the sales volumes and released their own netbooks which cannabilised their own low end laptop and desktop ranges.

In turn this irritated the army of PC resellers who found their commissions and margins were falling due to the lower ticket prices of netbooks.

The rise of the tablet

The one computer manufacturer who stayed aloof from the rush into low margin netbooks was Apple who had no reason to rush down the commodity computing rabbit hole. It was Steve Jobs who launched the product that made netbooks irrelevant.

“Netbooks aren’t better at anything… they are just cheaper, they are just cheap laptops” Jobs said at the iPad launch in January 2010.

Immediately the iPad redefined the computer market; those who’d been waiting a decade for a decent tablet computer scooped the devices up.

Executives who wouldn’t have dreamt of replacing their Blackberries with an iPhone, let alone using an Apple computer proudly showed off their shiny iPads.

The arrival of the iPad in boardrooms and executive suites also had the side effect of kick starting the Bring Your Own Device movement as CIOs and IT managers found that their policy of Just Say No was a career limiting move when the Managing Director wanted to connect her iPad to the corporate network.

Rebuilding PC margins

Around the time of the iPad’s released the major PC manufacturers declared a detente over netbooks and joined Intel in developing the Ultrabook specification.

The aim of the Ultrabook was to de-commodify the PC laptop market by offering higher quality machines with better margins.

While the Ultrabook has worked to a point, competition from tablet computers and the demands of consumers who’ve been trained to look for sub $500 portables means the more expensive systems are gradually coming down to the netbook’s price points.

Today’s Ultrabook will be next month’s netbook.

For the PC manufacturers, the lesson is that computers have been a commodity item for nearly a decade and only savvy marketing and product development – both of which have been Apple’s strengths – is the only way for long term success in the marketplace.

Those US based manufacturers who haven’t figured this out are only go to find that Chinese manufacturers – led by companies like Taiwan’s Asustek – will increasingly take the bottom end of the market from them.

The car industry is a good comparison to personal computers in commoditisation – with the passing of the netbook, the question is whether we’ll remember the eeePC as a Trabant, Model T Ford or a Volkswagen Beatle.

Blind faith in the algorithm

Putting too much faith in computer programs may cause problems for the unwary.

It’s fairly safe to say Apple’s ditching of Google Maps for their own navigation system has proved not to be company’s smartest move.

The humiliation of Apple was complete when the Victoria Police issued a warning against using the iPhone map application after people became lost in the desert when following faulty directions to the town of Mildura.

Mapping is a complex task and it’s not surpising these mistakes happen, particular given the dynamic nature of road conditions and closures. It’s why GPS and mapping systems incorporate millions of hours of input into the databases underlying these services.

Glitches with GPS navigations and mapping applications aren’t new. Some of the most notorious glitches have been in the UK where huge trucks have been directed down small country lanes only to find themselves stuck in medieval villages far from their intended location.

While those mishaps make for good reading, there are real risks in these misdirections. One of the best publicised tragedies of mis-reading maps was the death of James Kim in 2007.

Kim, a well known US tech journalist, was driving with his family from Portland, Oregan to a hotel on the Pacific Coast in November 2006 when they tried to take a short cut across the mountains.

After several hours driving the family became lost and stuck in snowdrifts and James died while hiking out to find help. His wife and two children were rescued after a week in the wilderness.

Remarkably, despite warnings of the risks, people still get stuck on that road. The local newspaper describes it the annual ritual as find a tourist in the snow season.

Partly this irresponsibility is due to our modern inability to assess risk, but a more deeper problem is blind faith in technology and the algorithms that decide was is good and bad.

A blind faith in algorithms is a risk to businesses as well – Facebook shuts down accounts that might be showing nipples, Google locks people out of their Places accounts while PayPal freeze tens of thousands of dollars of merchants’ funds. All of these because their computers say there is a problem.

Far more sinister is the use of computer algorithms to determine who is a potential terrorist, as many people who’ve inadvertently found themselves on the US government’s No Fly List have discovered.

As massive volumes of information is being gathered on individuals and businesses it’s tempting for all of us to rely on computer programs to tell us what is relevant and to join the dots between various data points.

While the computers often right, it is sometimes wrong as well and that’s why proper supervision and understanding of what the system is telling people is essential.

If we blindly accept what the computer tells us, we risk being stuck in our own deserts or a snowdrift as a result.

Tracks in the ether

Smartphones, the web and tracking technologies are giving governments and businesses more power than ever.

Bureaucrats dream of tracking every person or asset under their purview and the rise of technologies like smartphones, Global Positioning Systems (GPS) and Radio Frequency IDentity (RFID) chips are giving them more power than ever.

Two stories in the last week illustrated how these technologies are being used by authorities to monitor people; a school district in the United States is fighting a student who refuses to wear an RFID enabled identity card and Saudi immigration authorities are now sending text messages to guardians of travellers, mainly women, leaving the country.

In Saudi Arabia, the law prohibits minors and women from leaving the country without the permission of their adult male guardians. As the Riyadh Bureau website explains, to streamline the permission process Saudi authorities enabled online pre-registration for travellers so now male guardians can grant assent through a website rather than dealing with the immigration department’s paperwork every time their spouse or children wants to travel.

When the spouse or child passes through immigration, the guardian receives an SMS message saying their ward is about to leave the country. One assumes the male can withdraw that approval on receipt of the text.

The Saudi application is an interesting use of the web and smartphones to deliver government services and probably not what Western e-gov advocates are thinking of when they agitate for agencies to move more functions online.

More ominous is the story from the US where Wired Magazine reports Andrea Hernandez, a Texan student, is fighting her local school over the use of RFID enabled identity cards that track pupils’ attendance.

John Jay High School’s use of RFID tags is a classic case of bureaucrat convenience as electronic cards are far easier to manage and monitor than roll calls or sign-ins.

Incidentally John Jay High School has over 200 CCTV cameras monitoring students’ movements, as district spokesman Pascual Gonzalez says, “the kids are used to being monitored.”

The problem is that RFID raises a range of privacy and security issues which the bureaucrats either haven’t thought through or have decided don’t apply to their department.

Notable among those issues is that “has a bar code associated with a student’s Social Security number”. It never ceases to amaze just how, despite decades of evidence, US agencies and businesses keep using an identifier that has proved totally unsuited for the purposes it was developed for.

Probably the most worrying point from the Texan story is how school officials tried to suppress the story, offering Ms Hernandez’s father a compromise on the condition he “agree to stop criticizing the program and publicly support it.”

That urge to control criticism and dissent is probably the thing all of us should worry about when governments and businesses have the ability to track our movements.

In this respects, the Texas education officials are even more oppressive than Saudi anti-women laws. Something we should consider as more of our behaviour is tracked.
