Apple iPad replacing PCs as well as paper?

7 Comments

Now here’s an article to strike fear into Microsoft. Stuart Sumner reports on iPad trials at the BBC and in the Army. The BBC’s CIO John Linwood says:

We’re seeding the organisation [with the devices]. We put some iPads into production and some into management and other roles to see if people would be able to give up their desktops.

He goes on to say that the iPad may enable paperless meetings.

What makes an iPad better than a laptop or netbook for a meeting? I find it curious, incidentally, that the report refers to replacing desktops rather than laptops.

Well, one reason I have always liked tablets is that they are more interactive and don’t put a barrier (the screen) between you and others. A stylus is actually nice for meetings – good for quick diagrams as well as handwriting. Apple’s iPad lacks the stylus, but has other advantages over Windows tablets – smaller, lighter, instant-on, long battery life, and so on.

Still, the humble netbook at one third of the price will do the job too, better in some ways. You have Excel, for example. Unfortunately it lacks the elegance, usability and desirability of Apple’s device.

Any excuse to justify handing out cool devices, then? Maybe; but there’s no law that says business equipment has to be dull and unpleasant to use.

Oracle breaks, then mends Eclipse with new Java build

Somewhere in the JVM (Java Virtual Machine) is a company field, identifying the source of the JVM. Following its acquisition of Sun, Oracle reasonably enough changed the field in version 1.6.0_21 to reference Oracle rather than Sun.

Unfortunately some applications use the field to vary some command-line arguments according to which JVM is in use. “If Sun JVM do this, if IBM JVM do that.” Eclipse was one of these, so Oracle’s update caused “crashing and freezing issues” for Windows users. There is more information here.

When the problem was discovered, Oracle issued an update that reverts the change. Hence Ian Skerrett at Eclipse has posted Oracle Demostrates Great Community Support and Fixes Eclipse.

The issue demonstrates that almost any software change can have unintended consequences, especially if the software is an application runtime.

Should Oracle have checked for this before release? Possibly; though it cannot check every build against every application on every platform. Still, everyone has done the right thing here.

Will the JVM now say Sun for ever? I would think for some time to come, bearing in mind that companies may standardise on specific Eclipse builds and stay on them for an extended period.

Microsoft and the NHS: what went wrong?

2 Comments

Microsoft UK’s John Coulthard, Senior Director Healthcare and Life Sciences, has posted a comment on the decision by the NHS not to renew its EWA (Enterprise Wide Agreement) with Microsoft. His summary:

The bottom line is the NHS benefited from the productivity gains delivered through a suite of Microsoft software worth in excess of £270m per year. The actual cost to the NHS was £65m per year, delivering a saving of saving of £205m to the NHS and British taxpayers. For the next three years the cost would have risen to £85m as the NHS deploys more and more technology while the National Programme rolls out.

Software supplier whinging at loss of a lucrative contract? Of course; but at the same time I’d be interested to know whether this results in greater expense for UK taxpayers, of which I am one, and what is the real reason for the contract’s termination.

I’d like to think the decision is part of a strategy to end vendor lock-in and promote both competition and use of open source systems; but the truth may be less inspiring.

What are we to make of this report in Computer Weekly which says:

“Out of the blue, the Cabinet Office rejected the cut-down version of the renewal," said a source. "The noise from the top is that they are not sure national agreements work. It will be down to the trusts to make sure they are fully licensed."

One of the odd things reported is that the cut-down agreement was to have cost £21m, I presume annually; but the government is paying an immediate £50m to Microsoft:

The Cabinet Office did agree to pay Microsoft about £50m to cover software used in the previous agreement that was not licensed, but attributed the spend to the last administration’s budget.

That does not sound like a strategy to save money, when you consider the licensing costs now facing NHS trusts who no longer have an agreement in place.

Now, it is possible that the long-term effect will be to reduce lock-in, though that is optimistic; I do not know if any NHS trusts are actually planning to move away from Microsoft’s platform and even if they are, it is not something that can be done quickly. Another scenario is that most of them make their own agreements with Microsoft, the total cost of which exceeds what the EWA renewal would have cost.

Still, the outcome will probably please Google which has its own idea about how to provide IT for healthcare.

Nothing I’ve read really explains the decision and I would like to know more.

Stats that matter: Android grows in mobile, IE stops declining, eBooks take off

2 Comments

This should be three blog posts; but you’ve read this news elsewhere. Still, I can’t resist a brief comment on three recent trends.

Browsers

The first is that usage of Microsoft’s Internet Explorer has levelled off after a long period of decline. Microsoft says it is increasing but the numbers are too small to say that with confidence. StatCounter global stats for May to July show slight decline for IE (52.83% –> 52.37%) and FireFox (31.54%->30.88%), with Google Chrome the main beneficiary (8.81%->10.32%).

On this blog Chrome has grown from 4.2% to 12.4% in the last year. IE is still declining: 44.9% in July 09, 39.6% in June 10, and 38.2% in July 10.

My guess is that the success of Windows 7 might have brought back a few FireFox users. The interesting story though is where Chrome will be when it stops growing its share. My second guess is that it will be ahead of FireFox, though that is speculative. It is WebKit though, and I think that will be bigger than Mozilla’s Gecko thanks to adoption by Google, Apple, Adobe and others.

Mobile

Next, Google Android. Nielsen reports that it has pulled ahead of Apple iPhone in the US SmartPhone market; both are behind RIM’s Blackberry though that is in steady decline. RIM is announcing Blackberry 9800, the first on OS 6, later today; but I doubt it will disrupt Android’s growth. The developer angle is that Android is now equal to Apple’s iPad/iPhone in strategic importance, which will be a relief to Adobe – Flash runs on Android but not iPhone.

Android owners lack the satisfaction of Apple iPhone owners. 21% of them are eyeing the iPhone for their next upgrade, whereas only 6% of iPhone owners want Android next. Only 42% of Blackberry owners intend to remain loyal. It is all tending to confirm my speculation back in April that Android is the new Windows.

So in two years time, what will be the market share for RIM, Nokia Symbian/MeeGo, Windows Phone, HP Palm WebOS? It will not be easy for any of them.

eBooks

Finally, eBooks. The Kindle vs iPad vs Nook vs Sony is one story; but the bigger one is that the eBook is happening at last. David Carnoy’s recent articles on Amazon give the background. One is an interview with Amazon’s Ian Freed in which the retailer says eBook sales have tripled in the first quarter of 2010 vs that in 2009, and claims 70-80% of the market. Another looks at what Amazon didn’t say. However the market shares work out though, what matters is that screen, battery and wireless technology are now good enough, and publishers and authors willing enough, for eBooks to become mainstream, with huge implications for the media industry.

SOA, REST and Flash/Flex – why Flash does not PUT

Adobe’s Duane Nickull has an illuminating post on how the Flash player handles REST. Nickull is responding to a post by Malcolm Box in which he complains how hard it is to use Flash with a REST web service. Box observes that Flash cannot send POST, PUT and DELETE requests when running in the browser, and does not send cookies.

Nickull defends the Flash behaviour:

Flash’s HTTP libraries currently support GET and POST. My architectural view of this is that the HTTP libraries only should really support these and not worry about the others.

He also notes that cookies are a poor way to manage state:

Cookies are for the browser and belong in the browser. Having Flash Player able to access cookies would be a mistake in my own opinion. Any logic that is facilitated by a browser should probably be dealt with at the browser layer before Flash Player is used.

Now, I think the comments on REST are important to read if you are engaged in designing a web service, as many of us in these days of cloud+device. There is a kind-of “word on the street” approach to web services which says that REST is good, SOA/SOAP is bad; but in reality it is not so simple, and these distinctions are muddled. REST is arguably a form of SOA, you can do SOAP with REST, and so on.

One factor is that reading data in a web client is far more common than writing data. It is easy to be an advocate of the simplicity of REST if all you are doing is GET.

The question Nickull asks is whether the transport protocol has any business dictating how the data it transports should be processed, for example whether it is an operation to retrieve or to write data:

In an SOA world, the transport functionality (usually implemented using SOAP) should focus on just delivering the message and it’s associated payload(s) to the destination(s), optionally enforcing rules of reliability and security rather than declaring to the application layer processing instructions to the service endpoint.

Read the post for more of the rationale behind this. Maybe, even if you are doing REST, restricting your web service to GET and POST is not such a bad idea after all.

That said, whatever you think about the architectural principles, you may find yourself having to write a browser-hosted Flash client for a service that requires an HTTP verb other than GET or POST. There are ways round it: see this discussion of Amazon S3 (which uses PUT) and Flash for an example.

New Amazon Kindle with WebKit browser and free 3G internet

68 Comments

Never mind the books. Amazon’s new Kindle reader is offering as an “experimental feature” a web browser based on WebKit – the same engine as Apple Safari and Google Chrome – that is free to use over 3G networks:

New WebKit-Based Browser
Kindle’s new web browser is based on WebKit to provide a better web browsing experience. Now it’s easier than ever to find the information you’re looking for right from your Kindle. Experimental web browsing is free to use over 3G or Wi-Fi.

Amazon pays for the 3G coverage which is available globally. OK, it is monochrome, but since the Kindle also has a neat little keyboard is this now a great deal for blogging, checking Google maps, and so on?

Maybe not. Here’s what the terms and conditions say:

Use of Wireless Connectivity. Your Kindle uses wireless connectivity to allow you to shop for and download Digital Content from the Kindle Store. In general, we do not charge you for this use of wireless connectivity … You may use the wireless connectivity provided by us only in connection with the Service. You may not use the wireless connectivity for any other purpose.

If you are like me you may feel there is some inconsistency between these two statements. Enough to say that from my point of view free global web browsing would be a big incentive to purchase a Kindle; but I suspect that if this is real and turns out to be a popular feature consuming significant data traffic, Amazon will soon find a way to charge for it or turn it off.

It is also interesting to see a smidgen of convergence between the Kindle and more general-purpose slate devices. I am not sure if the Kindle strictly counts as a slate since it has a keyboard, but it certainly has the slate look and feel.

Day Software: another strategic acquisition for Adobe

Adobe has acquired Day Software, a company which specialises in web content management. Its products include the CRX Java Content Repository and the CQ5 Web Content Management Platform. One of its distinctive features is an emphasis on interaction and collaboration. Day’s chief scientist is Roy Fielding, co-founder of the Apache Software Foundation and well-known for his work on REST (Representational State Transfer).

The acquisition gives Adobe a stronger presence in the open source community, and it will be interesting to see if it influences controversial issues like the fact that the Flash Player is closed source, or that some of Adobe’s open source projects are not as collaborative as they could be.

I suspect though that Adobe is mainly aiming to broaden its technology to encompass web content management and to tie it together with its rich client platform, Flash and AIR. It is a good fit, since it is Java based and should work nicely with the existing LiveCycle pieces. We might also expect integration with Omniture web analytics as well as with the content authoring tools in Creative Suite.

Looks like a sane acquisition to me.

Dropbox: file sync that works, something for Ray Ozzie to think about

2 Comments

It all started when I wanted to get a document onto an iPhone. Apple makes this absurdly difficult, so I installed Dropbox, which does cloud synch of up to 2 GB free, more with subscription, across multiple platforms and devices: Windows, Mac, Linux, iPhone, Android, iPad and soon Blackberry.

I mentioned this on Twitter:

installed dropbox – live mesh but cross-platform and without the hassles?

and got several responses:

Dropbox is brilliant, I sync allsorts with it and use it as main storage on my netbook!

and

love that service, I couldn’t even get live sync to sign in!

and

I just updated my dropbox to the 50GB plan. Now have all my stuff synched across 5 macs/pcs + available on my iPhone.  Amazing

Now, Microsoft’s Live Mesh appeared in April 2008 and was meant to synch files across Windows, Mac and mobile, though the mobile client never really appeared. It has now been replaced by Windows Live Sync. There’s still no mobile support, not even for Windows mobile.

Dropbox launched publicly in September 2008 and now has a team of 28 people according to the About page – including the very capable Adam Gross formerly of Salesforce.com.

It seems to be an example of Microsoft having a good idea but being unable to deliver. The reason I mentioned “without the hassle” in my tweet is that Live Mesh always required a reboot and occasionally caused problems afterwards in my experience. Dropbox did not.

Ray Ozzie is Microsoft’s Chief Software Architect and seemed to be a key driver behind Live Mesh when it was announced. At one time it seemed that the technology might play a fundamental role in Microsoft’s efforts to unite cloud and device.

You can sign up for Dropbox free here.

Windows Phone 7 briefing report: no enterprise app deployment at launch

1 Comment

I attended a Microsoft briefing on Windows Phone 7 (WP7) yesterday. Here’s a quick summary of what interested me.

It does appear to be a decent phone. Unfortunately I’ve not yet received a preview device, but there’s no doubt that the user experience is well ahead of that on previous Windows Mobile devices.

The user interface is distinctive as you have no doubt seen. Microsoft is building strong links with both Facebook and Windows Live, surfaced at various places, and hopes this will be the best phone for social networking. It also hooks into Xbox Live, though it does not enable real-time multiplayer games, only turn-by-turn.

It has Bing maps with GPS support, though I suspect it will not be the equal of Google Maps on iPhone or Android. However, at least Microsoft is not in Apple’s position where it relies on a competitor for this key application.

One significant aspect for both users and developers is Tile Notifications. Each installed app has a tile which the user can install on the Start (home) page. These tiles can display text and image notifications that can be customized for the user. For example, a travel app could show a red alert and a message if a plane was cancelled or delayed. A sports app could show the latest score for your favourite team. However, there is no multi-tasking, so most of the time the app is not even running. How does this work?

The answer is that Microsoft hosts a notification server through which app vendors can push notifications. The app vendor needs to store on its own server any user-specific data, such as which flight she has booked. The app vendor can then push notifications to the user via Microsoft’s service. A more detailed explanation is here.

I like this form of notification since it is non-intrusive for the user. If you do not want to see them at all, you can just remove the tile from the Start page.

Microsoft confirmed that in-browser Silverlight will not work on launch. This strikes me as surprising, since Silverlight is built into the OS. I guess it will come later.

I asked a few questions.

When will we get Windows Phone 7? Microsoft is only saying “for Christmas 2010”.

Will it support tethering? No comment at the moment.

Will there be any way to copy a file from your PC to the device? I thought this would get a straightforward answer, but it did not. I was told that the PC side of WP7 has not been announced yet. However, it will bear some relation to what has been done before for Zune – though the UK still might or might not get the Zune Pass subscription service. Prompted by this discussion, I downloaded the Zune software. It is nicer to use than Windows Media Player, for sure. Why does Microsoft have two free media players, a good one that is reserved for a small niche of US users, and a mediocre one that comes with every version of Windows? You tell me.

Will there be any way to deploy applications without going through the Marketplace? The answer is mostly “No”, though Microsoft knows this is necessary for corporate apps and says there will be an announcement on the subject later this year. That said, there is a developer portal, intended for testing your apps, where you can specify up to 5 or 10 users who can download and install an app. This is in effect a limited private deployment, though it is not intended for that purpose.

Deploying apps to Windows Phone 7 will be slightly more expensive than it is for Apple’s iPhone. The policies are explained here. You pay $99 to register, which gets you five free submissions, after which it is $19.99 per app. Each registration is limited to five free apps, but there is no limit on paid apps. There is a 70/30 revenue split. The idea is to limit the number of low quality apps. Not a bad thing considering the amount of junk in Apple’s App Store.

Lies, damn lies, and Apple’s antenna-gate

Apple’s iPhone 4 is still relatively new; and I when I pulled it out of my pocket at a social occasion last weekend someone said, “isn’t that the new iPhone?” and another, “isn’t that the one with the aerial fault?”

Another person then showed his iPhone 4, with shattered screen. His had been dropped, an expensive slip of the wrist.

So there we have it, the two worst features of Apple’s new phone – fragility, and a dodgy antenna – exposed to all.

I have first hand-evidence then that the antenna issue is well-known. But how much will it affect sales? I received an email today from Opinium Research. According to their survey of 2000 UK adults, 26% are less likely to get an iPhone 4 because of this widely reported fault.

Pretty bad for Apple then – a quarter of their market gone. Well, no. This is an example of “ask a silly question”. If you ask someone, “does the antenna issue make you more or less likely to buy an iPhone 4,” what do you expect them to say? In fact, 13% of them said it was a non-issue, while 57% said it was irrelevant because they are not in the market for an iPhone 4 anyway.

The right question would be: “Have you changed your mind about getting an iPhone 4 because of the reported fault with the antenna?” I expect many fewer would tick the yes box.

Useless survey then. In my view the phone is fine, the antenna issue is minor, and Apple’s free case offer will sort it for most people.

Going back to my social occasion, by the end of the party Apple had at least one more would-be customer, despite the antenna and despite the fragility; and given that the phone is still out of stock everywhere I don’t think the company need worry too much – though its reaction to this wave of bad publicity has been interesting to watch.

Incidentally, I also had a briefing on Windows Phone 7 today – more on that later.
