Windows 8 will run on ARM processors – a natural home for Silverlight?

4 Comments

Microsoft announced today at CES in Las Vegas that the next version of Windows will run on ARM as well as Intel CPUs. But why? The reason is that ARM CPUs have huge momentum in mobile computing, thanks to their low power consumption. Microsoft wants Windows to support System on a Chip (SoC) architectures such as NVIDIA’s Tegra 2, which has two ARM Cortex-A9 CPUs combined with an HD-capable graphics processor in a single package. In its press release, the company is careful not to upset established x86/x64 partners Intel and AMD too much, emphasising that Windows will run on SoC packages based on those CPUs as well.

It is an interesting announcement, but one that raises as many questions as answers. The first concerns Microsoft’s mobile strategy, with Windows now seeming to encroach on territory that you have thought belonged to its embedded operating system, Windows CE, which underlies both Windows Mobile and Windows Phone 7. With all its legacy APIs, full-blown Windows does not seem ideal for low-powered, resource-constrained mobile devices; yet the company seems set on bringing full Windows rather than something based on Windows Phone 7 to the emerging tablet market.

The second issue is that applications will need at least re-compiling, and in many cases some re-coding, in order to run on ARM CPUs. Microsoft says it will deliver Office for ARM:

Sinofsky: Microsoft Office is an important part of customers’ PC experience and ensuring it runs natively on ARM is a natural extension of our Windows commitment to SoC architectures.

Windows and Office alone is enough for a decent business device; but customers who buy Windows on ARM expecting their existing games or applications to run will be disappointed.

We have been here before. In the early days of Windows CE, devices ran a variety of processors such as MIPS or Hitachi SH3, and developers had to compile multiple binaries and create setups that installed the right one on each device. In an attempt to overcome the friction this created, Microsoft introduced the Common Executable Format (CEF) with Windows CE 3.0 in 2000. This was an intermediate language format which was translated to native code by a “translator” when it was installed onto a device.

It sounds  a bit like .NET or Java; and it was indeed a forerunner of the .NET Common Language Runtime, which appeared in 2002. However, CEF never really caught on. Although it solved deployment issues, it introduced performance problems and was troublesome to debug. Most developers preferred to stick with true native code.

Today though .NET is mature; and we also have Silverlight, a cross-platform implementation of the .NET Framework combined with multimedia player and graphics framework. If Microsoft includes .NET and Silverlight in its ARM build of Windows, that would solve some of the deployment problems, especially for business devices. Many custom applications are built for .NET; and these would in principle run without any need to recompile, since a .NET executable is intermediate code which is compiled to native code at runtime, though any code which includes “platform invoke” calls to native APIs would not work.

It is surprising therefore that neither .NET nor Silverlight is mentioned in Windows president Steve Sinofsky’s Q&A about Windows on ARM. Still, we should not read too much into that. It would be madness if Microsoft did not support its .NET technologies on this new platform, would it not?

Hardware vendors chase Apple’s iPad at CES with Android, not Windows

1 Comment

There is a chorus of disapproval on the web today as Asus announced a full-fat Windows tablet  (Eee Slate EP121)  at CES in Las Vegas, along with three other devices running Google Android – the Eee Pad MeMo, the Eee Pad Transformer, and the Eee Pad Slider.

The most detailed “review” I’ve seen for the EP121 is on the Windows Experience Blog. Core i5, 4GB RAM, 64GB SSD, capacitive screen with touch and stylus input.

Nice in its way; but no kind of game-changer since this is an echo of early Windows slates which never achieved more than niche success. Four big disadvantages:

  • Short battery life
  • High price
  • The stylus
  • and another thing: in the rush to embrace touch computing, vendors appear to have forgotten one of the best features of those early tablets: you could rest your hand on the screen while writing with the pen. If you have a combined touch/stylus device that will not work.

Microsoft fans will be hoping CEO Steve Ballmer does not make too much of the EP121 and devices like this in tonight’s keynote. If he does, it will seem the company has learned little from failures of the past.

Asus deserves respect for introducing the netbook to the world in 2007, with the original Eee PC. It ran Linux, had an SSD in place of a hard drive, battery life was good, and above all it was light and cheap. Back then the story was how Microsoft missed the mark with its 2006 Origami project – small portable PCs running Windows – only to be shown how to do it by OEMs with simple netbooks at the right price.

Asus itself is not betting on Windows for tablet success; after all, three of the four products unveiled yesterday run Android. Despite what was apparently a poor CES press conference these may work out OK, though the prices look on the high side.

There will be many more tablets announced at CES, most of them running Android. Android “Honeycomb”, which is also Android 3.0 if Asus CEO Johnny Shih had his terminology right, is the first version created with tablet support in mind.

But why the tablet rush? The answer is obvious: it is because Apple has re-invented the category with the iPad. Since the iPad has succeeded where the Tablet PC failed, as a mass-market device, intuitively you would expect vendors to study what is right about it and to copy that, rather than repeating past mistakes. I think that includes long battery life and a touch-centric user interface; keyboard or stylus is OK as an optional extra but no more than that.

Equalling Apple’s design excellence and closed-but-seamless ecosystem is not possible for most manufacturers, but thanks to Android they can come up with devices that are better in other aspects: cheaper, more powerful, or with added features such as USB ports and Adobe Flash support.

It is reasonable to expect that at least a few of the CES tablets will succeed as not-quite iPads that hit the mark, just as Smartphones like the HTC Desire and Motorola Droid series have done with respect to the iPhone.

Microsoft? Ballmer’s main advantage is that expectations are low. Even if he exceeds those expectations, the abundance of Android tablets at CES shows how badly the company misjudged and mishandled the mobile market.

The implication for developers is that if you want app ubiquity, you have to develop for Android and iOS.

Microsoft could help itself and its developers by delivering a cross-platform runtime for the .NET Framework that would run on Android. I doubt Silverlight for Android would be technically difficult for Microsoft; but sadly after PDC it looks unlikely.

Ten big tech trends from 2010

8 Comments

This was an amazing year for tech. Here are some of the things that struck me as significant.

Sun Java became Oracle Java

Oracle acquired Sun and set about imposing its authority on Java. Java is still Java, but Oracle lacks Sun’s commitment to open source and community – though even in Sun days there was tension in this area. That was nothing to the fireworks we saw in 2010, with Java Community Process members resigning, IBM switching from its commitment to the Apache Harmony project to the official OpenJDK, and the Apache foundation waging a war of words against Oracle that was impassioned but, it seems, futile.

Microsoft got cloud religion

Only up to a point, of course. This is the Windows and Office company, after all. However – and this is a little subjective – this was the year when Microsoft convinced me it is serious about Windows Azure for hosting our applications and data. In addition, it seems to me that the company is willing to upset its partners if necessary for the sake of its hosted Exchange and SharePoint – BPOS (Business Productivity Online Suite), soon to become Office 365.

This is a profound change for Microsoft, bearing in mind its business model. I spoke to a few partners when researching this article for the Register and was interested by the level of unease that was expressed.

Microsoft also announced some impressive customer wins for BPOS, especially in government, though the price the customers pay for these is never mentioned in the press releases.

Microsoft Silverlight shrank towards Windows-only

Silverlight is Microsoft’s browser plug-in which delivers multimedia and the .NET Framework to Windows and Mac; it is also the development platform for Windows Phone 7. It still works on a Mac, but in 2010 Microsoft made it clear that cross-platform Silverlight is no longer its strategy (if it ever was), and undermined the Mac version by adding Windows-specific features that interoperate with the local operating system. Silverlight is still an excellent runtime, powerful, relatively lightweight, easy to deploy, and supported by strong tools in Visual Studio 2010. If you have users who do not run Windows though, it now looks a brave choice.

The Apple iPad was a hit

I still have to pinch myself when thinking about how Microsoft now needs to catch up with Apple in tablet computing. I got my first tablet in 2003, yes seven years ago, and it ran Windows. Now despite seven years of product refinement it is obvious that Windows tablets miss the mark that Apple has hit with its first attempt – though drawing heavily on what it learnt with the equally successful iPhone. I see iPads all over the place, in business as well as elsewhere, and it seems to me that the success of a touch interface on this larger screen signifies a transition in personal computing that will have a big impact.

Google Android was a hit

Just when Apple seemed to have the future of mobile computing in its hands, Google’s Android alternative took off, benefiting from mass adoption by everyone-but-Apple among hardware manufacturers. Android is not as elegantly designed or as usable as Apple’s iOS, but it is close enough; and it is a relatively open platform that runs Adobe Flash and other apps that do not meet Apple’s approval. There are other contenders: Microsoft Windows Phone 7; RIM’s QNX-based OS in the PlayBook; HP’s Palm WebOS; Nokia Symbian and Intel/Nokia MeeGo – but how many mobile operating systems can succeed? Right now, all we can safely say is that Apple has real competition from Android.

HP fell out with Microsoft

Here is an interesting one. The year kicked off with a press release announcing that HP and Microsoft love each other to the extent of $250 million over three years – but if you looked closely, that turned out to be less than a similar deal in 2006. After that, the signs were even less friendly. HP acquired Palm in April, signalling its intent to compete with Windows Mobile rather than adopting it; and later this year HP announced that it was discontinuing its Windows Home Server range. Of course HP remains a strong partner for Windows servers, desktops and laptops; but these are obvious signs of strain.

The truth though is that these two companies need one another. I think they should kiss and make up.

eBook readers were a hit

I guess this is less developer-oriented; but 2010 was the year when electronic book publishing seemed to hit the mainstream. Like any book lover I have mixed feelings about this and its implications for bookshops. I doubt we will see books disappear to the same extent as records and CDs; but I do think that book downloads will grow rapidly over the next few years and that paper-and-ink sales will diminish. It is a fascinating tech battle too: Amazon Kindle vs Apple iPad vs the rest (Sony Reader, Barnes and Noble Nook, and others which share their EPUB format). I have a suspicion that converged devices like the iPad may win this one, but displays that are readable in sunlight have special requirements so I am not sure.

HTML 5 got real

2010 was a huge year for HTML 5 – partly because Microsoft announced its support in Internet Explorer 9, currently in beta; and partly because the continued growth of browsers such as Mozilla Firefox, and the WebKit-based Google Chrome, Apple Safari and numerous mobile browsers showed that HTML 5 would be an important platform with or without Microsoft. Yes, it is fragmented and unfinished; but more and more of HTML 5 is usable now or in the near future.

Adobe Flash survived Apple and HTML 5

2010 was the year of Steve Jobs’ notorious Thoughts on Flash as well as a big year for HTML 5, which encroaches on territory that used to require the services of a browser plug-in. Many people declared Adobe Flash dead, but the reality was different and the company had a great year. Apple’s focus on design and usability helps Adobe’s design-centric approach even while Apple’s refusal to allow Flash on its mobile computers opposes it.

Windows 7 was a hit

Huge relief in Redmond as Windows 7 sold and sold. The future belongs to mobile and cloud; but Windows is not going away soon, and version 7 is driving lots of upgrades as even XP diehards move over. I’m guessing that we will get first sight of Windows 8 in 2011. Another triumph, or another Vista?

Adobe declares glittering results as CEO says Apple’s Flash ban has no impact on its revenue

3 Comments

Adobe has proudly declared its first billion dollar quarter, $1,008 m in the quarter ending Dec 3 2010 versus $757.3 m in the same quarter of 2009.

I am not a financial analyst, but a few things leap out from the figures. One is that Omniture, the analytics company Adobe acquired at the end of 2009, is doing well and contributing significantly to Adobe’s revenue – $98.4 m in Q4 2010. The billion dollar quarter would not have happened without it. Second, Creative Suite 5 is selling well, better than Creative Suite 4.

Creative Suite 4 was released in October 2008, and Creative Suite 5 in April 2010. It is not perfect, but the following table compares the Creative Solutions segment (mainly Creative Suite) of the two products quarter by quarter from their respective release dates:

Quarters after release 1st 2nd 3rd 4th 5th 6th
Creative Suite 4 508.7 460.7 411.7 400.4 429.30 432.0
Creative Suite 5 532.7 549.7 542.1      

CS4 drops off noticeably following an initial surge, whereas CS5 has kept on selling. It is a good product and a de-facto industry standard, but not every user is persuaded to upgrade every time a new release appears. My guess is that things like better 64-bit support – which make a huge difference in the production tools – and new tricks in PhotoShop have been successful in driving upgrades to CS5. Further, the explosion of premium mobile devices led by Apple’s iPhone and iPad has not been bad for Adobe despite Apple CEO Steve Jobs doing his best to put down Flash. Publishers creating media for the iPad, for example, will most likely use Adobe’s tools to do so. CEO Shantanu Narayen said in the earnings calls, “We have not seen any impact on our revenue from Apple’s choice [to not support Flash]”, though I am sure he would make a big deal of it if Apple were to change its mind.

Before getting too carried away though, I note that Creative Suite 3, published in March 2007, did just as well as CS5.  Here are the figures:

Quarters after release 1st 2nd 3rd 4th 5th 6th
Creative Suite 3 436.6 545.5 570.5 543.5 527.2 493.6

In fact, Q4 2007 at $570.5 m is still a record for Adobe’s Creative Solutions segment. So maybe CS4 was an unfortunate blip. Then again, not quite all the revenue in Creative Solutions is the suite; it also includes Flash Platform services such as media streaming. Further, the economy looked rosier in 2007.

Here is the quarter vs quarter comparison over the whole company:

  Q4 2009 Q4 2010
Creative Solutions 429.3 542.1
Digital Enterprise 211.8 274.10
Omniture 26.3 98.4
Platform 47 46.1
Print and publishing 42.9 47.3

In this table, Creative Solutions has already been mentioned. Digital Enterprise, formerly called Business Productivity, includes Acrobat, LiveCycle and Connect web conferencing. Platform is confusing; according to the Q4 09 datasheet it includes the developer tools, Flash Platform Services and ColdFusion. However, the Q4 10 datasheet omits any list of products for Platform, though it includes them for the other segments, and lists ColdFusion under Print and Publishing along with Director, Contribute, PostScript, eLearning Suite and some other older products. According to this document [pdf] InDesign which is huge in print publishing is not included in Print and Publishing, so I guess it is in Creative Solutions.

In the earnings call, Adobe’s Mark Garrett did mention Platform, and attributed its growth (compared to Q3 2010) to “higher toolbar distribution revenue driven primarily by the release of the new Adobe Reader version 10 in the quarter.” This refers to the vile practice of foisting a third-party toolbar (unless they opt-out) on people forced to download Adobe Reader because they have been send a PDF. Perhaps in the light of these good results Adobe could be persuaded to stop doing so?

I am not sure how much this breakdown can be trusted as it makes little sense to me. Do not take the segment names too seriously then; but they are all we have when it comes to trying to compare like with like.

Still, clearly Adobe is doing well and has successfully steered around some nasty rocks that Apple threw in its way. I imagine that Microsoft’s decision to retreat from its efforts to establish Silverlight as a cross-platform rival to Flash has also helped build confidence in Adobe’s platform. The company’s point of vulnerability is its dependence on shrink-wrap software for the majority of its revenue; projects like the abandoned Rome show that Adobe knows how to move towards cloud-deployed, subscription-based software but with business booming under its current model, and little sign of success for cloud projects like Acrobat.com, you can understand why the company is in no hurry to change.

The top Silverlight feature request: implement on more platforms

7 Comments

One of the things mentioned by Microsoft VP Scott Guthrie in his Firestarter keynote yesterday was that Silverlight 5, the new version set for release in 2011, implements some 70% of what users have voted for. I presume he means the feedback forum here. But look what the top request is – as noted by a comment to yesterday’s post:

image

Looking at the comments, Android is a common request, and relatively easy for Microsoft to achieve given the open nature of that platform.

This was apparently not part of the 70% though. Instead, Guthrie introduced more Windows-only features – showing that concerns about divergence between Windows and Mac implementations when Microsoft announced COM support at the 2009 PDC were justified.

What if Microsoft had purchased Novell, or purchased Mono from Novell, instead of letting it go to Attachmate? It would have enabled Microsoft to unify the Windows and Linux implementations as well as building on the work the Mono team has done on compilation for iOS.

That dream is over though; the Silverlight application strategy seems focused on making it better for Windows-platform corporations.

Silverlight 5 unveiled: more power, more Windows

9 Comments

Microsoft has announced details of Silverlight 5, a major new release of its browser plug-in and desktop runtime for Windows and Mac. Silverlight is also the primary application runtime for Windows Phone 7, though this update does not apply to the phone yet. Silverlight 5 will go into beta in the first half of 2011, and release is planned for the second half of 2011 – no more than a year or so away.

So what’s in Silverlight 5?

On the media side, there is hardware decoding of H.264 video (an overdue feature) plus enhancements including TrickPlay which enables fast-forward and rewind. There is also remote control support of some kind. According to VP Scott Guthrie, you will be able to stream HD video to a netbook.

The bigger area of change is in Silverlight as an application runtime. Here are the highlights:

  • Text rendering is much improved, with multi-columns, OpenType support, and control of tracking and leading.
  • Postscript vector printing greatly improves printing support, and you can now create a dedicated print view different from what is on screen.
  • A new hardware-accelerated 3D graphics API, as well as immediate mode graphics which lets you render directly to the GPU.
  • There is a 64-bit version of Silverlight 5.
  • WS-Trust support for secure messaging in tandem with Windows Communication Foundation.
  • Databinding enhancements, and support for debugging a binding by setting a breakpoint on it.

Alongside these, trusted Silverlight applications have new capabilities. But what is a trusted application? In the past, Silverlight applications become trusted if they run out of the browser and the user gives permission via a dialog. In Silverlight 5 this changes. A Silverlight application can be trusted within the browser as well, though Microsoft says this only works “when enabled via a group policy registry key and an application certificate”. This implies that the feature is aimed at corporate environments rather than for applets with a broad reach.

Once trusted, an in-browser Silverlight applet has the following additional features:

  • A new web browser control lets you host HTML content within a Silverlight application.
  • Read and write access to My Documents
  • Ability to launch Microsoft Office applications – examples include creating an email message or opening a report in Word
  • Access to COM components – Microsoft gives the example of accessing a USB security key or a bar-code scanner
  • Ability to call native code vith PInvoke (Platform Invoke)

In addition, out of browser applications support multiple windows including child windows, so they can be made to behave even more like normal desktop Windows applications.

You can see the theme here: making trusted Silverlight applications more powerful so that a larger proportion of custom business applications can be implemented in the browser or as Silverlight out-of-browser applications, rather than as traditional Windows applications that require desktop deployment. Put this together with Office 365 and Windows Azure, and you can see how well Silverlight works as a component in Microsoft’s cloud stack – provided users do not have anything inconvenient like an Apple iPad.

But what about the Mac? All these “trusted” features appear to be Windows-only. I asked about Mac support and was told:

We’re evaluating mechanisms for enabling similar trusted applications on the mac.

Fair enough; but the way this is put does suggest that having retreated from any ambitions for broad device reach in statements at the recent PDC conference, it now seems that Microsoft is further retreating from Mac and Windows parity, and moving Silverlight more towards being an application runtime for Windows – though note that there will still be a Silverlight 5 for the Mac and which will have the features that do not require COM or PInvoke.

It is disappointing that there is still no built-in local database support, though there are third-party offerings.

There are a couple of ways to look at Silverlight. Microsoft’s lack of commitment to cross-platform parity and its unwillingness to address broad device support means it does not look good as a broad-reach browser plugin, despite its great features on systems that do support it.

On the other hand, as an alternative to desktop Windows applications Silverlight looks increasingly attractive as its capabilities increase.

More information on the new features here – though note it neglects to mention what will and will not work on a Mac.

HTML 5 Canvas: the only plugin you need?

2 Comments

The answer is no, of course. And Canvas is not a plugin. That said, here is an interesting proof of concept blog and video from Alexander Larsson: a GTK3 application running in Firefox without any plugin.

image

GTK is an open source cross-platform GUI framework written in C but with bindings to other languages including Python and C#.

So how does C native code run the browser without a plugin? The answer is that the HTML 5 Canvas element, already widely implemented and coming to Internet Explorer in version 9, has a rich drawing API that goes right down to pixel manipulation if you need it. In Larsson’s example, the native code is actually running on a remote server. His code receives the latest image of the application from the server and transmits mouse and keyboard operations back, creating the illusion that the application is running in the browser. The client only needs to know what is different in the image as it changes, so although sending screen images sounds heavyweight, it is amenable to optimisation and compression.

It is the same concept as Windows remote desktop and terminal services, or remote access using vnc, but translated to a browser application that requires no additional client or setup.

There are downsides to this approach. First, it puts a heavy burden on the server, which is executing the application code as well as supplying the images, especially when there are many simultaneous users. Second, there are tricky issues when the user expects the application to interact with the local machine, such as playing sounds, copying to the clipboard or printing. Everything is an image, and not character-by-character text, for example. Third, it is not well suited to graphics that change rapidly, as in a game with fast-paced action.

On the other hand, it solves an immense problem: getting your application running on platforms which do not support the runtime you are using. Native applications, Flash and Silverlight on Apple’s iPad and iPhone, for example. I recall seeing a proof of concept for Flash at an Adobe MAX conference (not the most recent one) as part of the company’s research on how to break into Apple’s walled garden.

It is not as good as a true local application in most cases, but it is better than nothing.

Now, if Microsoft were to do something like this for Silverlight, enabling users to run Silverlight apps on their Apple and Linux devices, I suspect attitudes to the viability of Silverlight in the browser would change considerably.

The Java crisis and what it means for developers

9 Comments

What is happening with the Java language and runtime? Since Java passed into the hands of Oracle, following its acquisition of Sun, there has been a succession of bad news. To recap:

  • The JavaOne conference in September 2010 was held in the shadow of Oracle OpenWorld making it a less significant event than in previous years.
  • Oracle is suing Google, claiming that Java as used in the Android SDK breaches its copyright.
  • IBM has abandoned the Apache open source Harmony project and is committing to the Oracle-supported Open JDK. Although IBM’s Sutor claims that this move will “help unify open source Java efforts”, it seems to have been done without consultation with Apache and is as much divisive as unifying.
  • Apple is deprecating Java and ceasing to develop a Mac-specific JVM. This should be seen in context. Apple is averse to runtimes of any kind – note its war against Adobe Flash – and seems to look forward to a day when all or most applications delivered to Apple devices come via the Apple-curated and taxed app store. In mitigation, Apple is cooperating with the OpenJDK and OpenJDK for Mac OS X has been announced.
  • Apache has written a strongly-worded blog post claiming that Oracle is “violating their contractual obligation as set forth under the rules of the JCP”, where JCP is the Java Community Process, a multi-vendor group responsible for the Java specification but in which Oracle/Sun has special powers of veto. Apache’s complaint is that Oracle stymies the progress of Harmony by refusing to supply the test kit for Java (TCK) under a free software license. Without the test kit, Harmony’s Java conformance cannot be officially verified.
  • The JCP has been unhappy with Oracle’s handling of Java for some time. Many members disagree with the Google litigation and feel that Oracle has not communicated well with the JCP. JCP member Doug Lea stood down, claiming that “the JCP is no longer a credible specification and standards body”. Another member, Stephen Colebourne, has a series of blog posts in which he discusses the great war of Java and what he calls the “unravelling of the JCP”, and recently  expressed his view that Oracle was trying to manipulate the recent JCP elections.

To set this bad news in context, Java was not really in a good way even before the acquisition. While Sun was more friendly towards open source and collaboration, the JCP has long been perceived as too slow to evolve Java, and unrepresentative of the wider Java community. Further, Java’s pre-eminence as a pervasive cross-platform runtime has been reduced. As a browser plug-in it has fallen behind Adobe Flash, the JavaFX initiative failed to win wide developer support, and on mobile it has also lost ground. Java’s advance as a language has been too slow to keep up with Microsoft’s C#.

There are a couple of ways to look at this.

One is to argue that bad news followed by more bad news means Java will become a kind of COBOL, widely used forever but not at the cutting edge of anything.

The other is to argue that since Java was already falling behind, radical change to the way it is managed may actually improve matters.

Mike Milinkovich at the Eclipse Foundation takes a pragmatic view in a recent post. He concedes that Oracle has no idea how to communicate with the Java community, and that the JCP is not vendor-neutral, but says that Java can nevertheless flourish:

I believe that many people are confusing the JCP’s vendor neutrality with its effectiveness as a specifications organization. The JCP has never and will never be a vendor-neutral organization (a la Apache and Eclipse), and anyone who thought it so was fooling themselves. But it has been effective, and I believe that it will be effective again.

It seems to me Java will be managed differently after it emerges from its crisis, and that on the scale between “open” and “proprietary” it will have moved towards proprietary but not in a way that destroys the basic Java proposition of a free development kit and runtime. It is also possible, even likely, that Java language and technology will advance more rapidly than before.

For developers wondering what will happen to Java at a technical level, the best guide currently is still the JDK Roadmap, published in September. Some of its key points:

  • The open source Open JDK is the basis for the Oracle JDK.
  • The Oracle JDK and Java Runtime Environment (JRE) will continue to be available as free downloads, with no changes to the existing licensing models.
  • New features proposed for JDK 7 include better support for dynamic languages and concurrent programming. JDK 8 will get Lambda expression.

While I cannot predict the outcome of Oracle vs Google or even Apache vs Oracle, my guess is that there will be a settlement and that Android’s momentum will not be disrupted.

That said, there is little evidence that Oracle has the vision that Sun once had, to make Java truly pervasive and a defence against lock-in to proprietary operating systems. Microsoft seems to have lost that vision for .NET and Silverlight as well – though the Mono folk have it. Adobe still has it for Flash, though like Oracle it seems if anything to be retreating from open source.

There is therefore some sense in which the problems facing Java (and Silverlight) are good for .NET, for Mono and for Adobe. Nevertheless, 2010 has been a bad year for write once – run anywhere.

Update: Oracle has posted a statement saying:

The recently released statement by the ASF Board with regard to their participation in the JCP calling for EC members to vote against SE7 is a call for continued delay and stagnation of the past several years. We would encourage Apache to reconsider their position and work together with Oracle and the community at large to collectively move Java forward.  Oracle provides TCK licenses under fair, reasonable, and non-discriminatory terms consistent with its obligations under the JSPA.   Oracle believes that with EC approval to initiate the SE7 and SE8 JSRs, the Java community can get on with the important work of driving forward Java SE and other standards in open, transparent, consensus-driven expert groups.   This is the priority.   Now is the time for positive action.  Now is the time to move Java forward.

to which Apache replies succinctly:

The ball is in your court. Honor the agreement.

Understanding the Silverlight controversy

23 Comments

There has been much discussion of the future of Microsoft’s Silverlight plugin since Server and Tools President Bob Muglia’s statement in a PDC interview that “Our strategy with Silverlight has shifted”, and spoke of HTML as the “only true cross platform solution”.

The debate was even reported on the BBC’s web site under the headline Coders decry Silverlight change.

It is unfortunate that headlines tend to think in binary; alive or dead. In other words, if Microsoft is repositioning Silverlight then it must be killing it.

That is not the case. Muglia did not say that Silverlight has no future, nor that it was unimportant. He affirmed that there will be another version of Silverlight for Windows and Mac, as well as highlighting that it is the development platform for Windows Phone.

Speaking personally for a moment, I have reviewed Silverlight favourably in the past and still regard it as a great achievement by Microsoft: the power of the .NET runtime, the elegance of C#, the flexible layout capabilities of XAML, integrated with a capable multimedia player, and wrapped in a lightweight package that in my experience installs quickly and easily.

Silverlight forms an excellent client for cloud services such as those delivered by the Azure platform which we heard about at PDC.

Perhaps it is the case that IE9 maestro Dean Hachamovitch tended towards the gleeful as he demonstrated features in HTML and JavaScript that previously would have required Silverlight or Flash. At the same time, IE9 is not yet released, and even when it is, will not match the capabilities or the tooling and libraries available for Silverlight.

The Silverlight press generated by PDC must have been disappointing and frustrating for Microsoft’s Silverlight team. I am reading reports of Developer VP Scott Guthrie’s remarks at the DevConnections conference this week.

The reports of my death are greatly exaggerated … I have more people working on Silverlight now than any time in Silverlight history … don’t believe everything you read on the internet.

I have great respect for Guthrie; you need only see the speed and manner with which he reacted to the recent ASP.NET security scare – not trying to diminish its importance, delivering practical advice, answering comments, and working with his team to come up with workarounds and a proper solution as quickly as possible – to appreciate his commitment and that he understands the needs of developers.

So were posts like my own Silverlight dream is over unfair and inaccurate? Well, there is always a risk of being misunderstood; but the problem, as I perceive it, is not primarily about Silverlight’s progress on Windows and Mac. The problem is that those two desktop platforms no longer have sufficient reach; or rather, even if they have sufficient reach today, they will not tomorrow. We have the rise of iOS and Android; an explosion of non-Windows tablets in the wings; we have a man like James Gardner, CTO at the UK’s Department for Work and Pensions, writing of Windows 7 that:

Personally, I think it likely this is  the last version of Windows anyone ever widely deploys

In other words, Guthrie’s team can do a cracking job with Silverlight 5 for Windows and Mac – it could even merge Silverlight with WPF and make it the primary application platform for Windows – but that would still not address the concerns raised by what happened at PDC. If Silverlight remains imprisoned in Windows and Mac, it cannot deliver on its original promise.

What could Microsoft do to restore confidence in Silverlight? Something along these lines would make me change my mind:

  1. Announce Silverlight for Android.
  2. Nurture Silverlight for Symbian.
  3. Follow through on commitments for Silverlight on Moblin/MeeGo.
  4. Either implement Silverlight for Linux, or enter a deeper partnership with Novell’s Mono so that Microsoft-certified Silverlight runtimes appear on Linux in a timely manner alongside Microsoft’s releases.
  5. Come up with a solution for Silverlight on iOS. One idea is to follow Adobe with a native code compiler from Silverlight to iOS. Another would be a way of compiling XAML and C# to SVG and JavaScript. Neither would be perfect; but as it is, every company that starts deploying iPads or their successors is a customer that cannot use Silverlight.

Do I think Microsoft will implement the above? I doubt it. My interpretation of Muglia’s remarks is that Microsoft has decided not to go down that path, but to reserve Silverlight for Windows, Mac, and Windows Phone, and to invest in HTML for broad-reach applications.

That may well be the right decision; it is one that makes sense, though Microsoft was perhaps unwise to highlight it before IE9 is released. Further, cross-platform is not in Microsoft’s blood, and the path that Silverlight has taken is in line which what you would expect from a company built on Windows.

Silverlight is not dead, and for developers targeting Windows, Mac and Windows Phone it is as good as ever, and no doubt will be even better in its next version. But failing another change of heart, it will never now be WPF Everywhere; and PDC 2010 was when that truth sank home.

Update: this is pretty much what Guthrie says in his latest post:

Where our strategy has shifted since we first started working on Silverlight is that the number of Internet connected devices out there in the world has increased significantly in the last 2 years (not just with phones, but also with embedded devices like TVs), and trying to get a single implementation of a runtime across all of them is no longer really practical (many of the devices are closed platforms that do not allow extensibility).  This is true for any single runtime implementation – whether it is Silverlight, Flash, Java, Cocoa, a specific HTML5 implementation, or something else.  If people want to have maximum reach across *all* devices then HTML will provide the broadest reach (this is true with HTML4 today – and will eventually be true with HTML5 in the future).  One of the things we as a company are working hard on is making sure we have the best browser and HTML5 implementation on Windows devices through the great work we are doing with IE9.

Adobe MAX 2010 – it’s all about the partners

Last week was all conferences – Adobe MAX 2010 followed by Microsoft PDC – which left me with plenty of input but too little time to write it up. It is not too late though; and one advantage of attending these two events back-to-back was to highlight the tale of two runtimes, Adobe Flash and Microsoft Silverlight. MAX was a good event for Flash, and PDC a bad one for Silverlight, though the tale has a long way yet to run.

The key difference at this point is not technical, but all about partners. At MAX we saw how the Flash runtime is integral to the Blackberry PlayBook, with RIM founder Mike Lazaridis coming on stage to tell us so. Flash is also built into Google TV, and Andres Ferrate and Daniels Lee from Google Developer Relations presented a session on creating web apps for the platform – worth watching as it brings out the difference between developing for a TV “lean back” environment and traditional mouse or touch user interfaces -  and we also heard from Samsung about its Flash-enabled TVs coming in 2011. In each case, it is not just Flash but AIR, for applications that run outside the browser, which is supported. Google TV runs Android; and AIR for Android in general drew attention at MAX, encouraged by free Motorola Droid 2 smartphones handed out to attendees.

If the task was to convince Flash developers – and those on the fence – that the platform has a future, MAX delivered in spades; and Adobe can only benefit from the uncertainty surrounding the most obvious runtime rivals to Flash, Java and Silverlight.

But what about that other platform, HTML? Well, Adobe made a bit of noise about projects like EDGE, which exports animations and transitions to SVG and JavaScript using an extended JQuery library, as well as showing a “sneak peek” of a tool to export a Flash animation (but not application) to  HTML. Outside the Adobe fan club there is still considerable aversion to Flash, stoked by Apple; in one of the sessions at MAX we were told that Steve Jobs’ open memo Thoughts on Flash has done real damage.

My impression though is that Adobe still has a Flash-first philosophy. The Solution Accelerators announced for LiveCycle 2.5, for example, all seem to be based on Flash clients, which could prove difficult if Apple’s iPad continues to take off in the enterprise. Adobe could do more to provide JavaScript libraries for LiveCycle clients, and tools for creating HTML applications. If you came to MAX looking for evidence that Adobe is moving towards web standard HTML clients, you would have been largely disappointed; though seeing JQuery guy John Resig in the day two keynote would give you some comfort.

Some other MAX highlights:

  • Round-tripping between Catalyst and Flash Builder at last. This makes Catalyst more useful, though I still find myself thinking that the Catalyst features could be rolled into one of the other products, either as a designer personality for Flash Builder, or maybe in Flash Professional. The former would be easier as both Catalyst and Flash Builder are built on Eclipse.
  • Enhancements in the Flash Player – I am writing a separate piece on this, but it is great to see the 3D extensions codenamed Molehill, which together with game controller support lay the foundations for Flash games that compete more closely with console games.
  • Analytics – Adobe’s acquisition of Omniture a year ago was a far-sighted move, and the company talked about analytics in the context of applications as well as web sites. Despite unsettling privacy implications, the ability for developers to drill down into exactly how an application is used, and which parts are hardly used, has great potential for improving usability.
  • Digital publishing – it was fascinating to hear from publisher Condé Nast about its plans for digital publishing, using Adobe’s Digital Publishing Suite to create files targeting Adobe’s content viewer on iOS and eventually AIR. As a web enthusiast I have mixed feelings, and there was some foot-shuffling when I asked about SEO (Search Engine Optimisation); but as someone with a professional interest in a flourishing media industry I also hope this becomes a solid and profitable platform.

Disappointments? I was sorry to hear that Adobe is closing down contributions and reducing transparency in the open source Flex SDK, though it is said to be temporary. It also seems that plans to enhance ActionScript are not well advanced; Silverlight remains well ahead in this respect with its C# and .NET support.

What about Adobe’s enterprise ambitions? Klint Finley’s post on the Adobe Stack and what it means for Enterprise Development is a good read. The pieces are almost in place, but the focus on document processing at the back end, and Flash and Acrobat on the front end, makes this a specialist rather than a generic application platform.

Overall though it was a strong MAX. I appreciate Adobe for not being Google or Apple or Microsoft or IBM, and hope that takeover rumours remain as rumours.
