WebKit dominance threatens mobile web standards – but who will care?

tim — Thu, 09 Feb 2012 17:14:53 +0000

Daniel Glazman, co-chairman of the W3C CSS working group, has written a strongly-worded post describing how the “over-dominance” of the WebKit rendering engine threatens web standards.

Everyone loves the open source WebKit, so how is this so? The issue is a complex one. Those who make web browsers do not want to be tied only to those standards already ratified by the W3C as part of HTML or CSS. Therefore, they add features, sometimes in the hope that they will become standards, but use a vendor-specific prefix such as -webkit-,-moz- or -ms-. If you use those features in your markup, you do so in the awareness that they will only work on that specific vendor’s browser. The idea is that the best vendor-specific extensions become standard, in which case the prefix is dropped; or are replaced by an equivalent standard, in which case the prefix is also dropped. This has become an accepted part of the way standards are formed.

The issue now is that WebKit dominates the mobile web to the extent that web authors can assume its use without losing many users. WebKit is used in Apple iOS, Google Android, RIM BlackBerry 6 and higher, as well as on the desktop in Apple Safari and Google Chrome. Amazon also uses WebKit in the Kindle and of course the Android-based Kindle Fire.

The consequence, says Glazman, is that:

technically, the mobile Web is full of works-only-in-WebKit web sites while other browsers and their users are crying.

The further consequence, and this is Glazman’s strongest point, is that other browsers will have to pretend to be WebKit and support its extensions in order to give users a good experience – even if they have their own vendor-specific extensions that support the same features:

All browser vendors let us officially know it WILL happen, and rather sooner than later because they have, I quote, "no other option".

Glazman says “all browser vendors” which suggests that even Microsoft will do this, though that would be a surprising development.

This would mean that the -webkit- vendor-specific extensions were no longer vendor-specific. It would also meant that WebKit is in effect able to create web standards without the bother of going through the W3C:

It will turn a market share into a de facto standard, a single implementation into a world-wide monopoly. Again. It will kill our standardization process. That’s not a question of if, that’s a question of when.

says Glazman, suggesting that there is a risk of a return to the bad days when the dominance Microsoft’s IE6 prevented standards from evolving.

The parallel with IE6 is weak. IE6 was not an open source project, and the damage it did was in part because Microsoft deliberately chose not to invest in advancing HTML, preferring to drive users towards rich internet-connected Windows applications. It is difficult to see how that can happen to WebKit.

Nevertheless, the situation with WebKit is making it difficult for other mobile browsers to compete and does undermine the standards process. This is not really the fault of the WebKit team, though the W3C would like to see support for obsolete vendor-specific extensions dropped more quickly to discourage their use. Rather, it is a consequence of web authors seeing little value in adding support for other browsers that have little actual use on the mobile web.

It is worth observing that Glazman is a Mozilla guy, and his company Disruptive Innovations makes Mozilla extensions.

How can this be resolved? Glazman and others are right to raise awareness of the issue, but I doubt that many outside the standards community or browser vendors themselves will see this as a major problem.

The best fix would be for non-WebKit browsers to become more popular on the mobile web. Growing use of Windows Phone, for example, would give web authors more incentive to fix their markup. Another route to improving standards is via tools which do the right thing. Adobe’s strong support for CSS in Dreamweaver, for example, gave a significant boost to its use and helped to rescue us from font tags and the like.

Finally, it seems to me that the distinction between the “mobile” web and the “full” web is blurring, and rightly so. Users on mobile devices often tap the “full site” link where available since they have big enough screens to benefit. WebKit does not yet dominate the desktop Web.

On BlackBerry 10, Cascades UI and Adobe AIR

tim — Wed, 08 Feb 2012 17:03:35 +0000

I spoke to Jeff Lejeune, RIM’s Advanced User Interface Director, here at BlackBerry DevCon Europe in Amsterdam.

He is part of the team responsible for the Cascades UI, a native code UI framework for the forthcoming BlackBerry 10 OS. One of the things he told me is that the Cascades name is actually being used for parts of the API beyond the user interface. It is a major part of the new operating system.

I had not appreciated until today the extent of the likely difference between BlackBerry 10 and the current Tablet OS 1.0 or Playbook OS 2.0. Since the PlayBook OS is already based on QNX, I had assumed that BlackBerry 10 would be an incremental update rather than a radical new direction.

Certainly there is less difference between PlayBook OS 2.0 and BlackBerry 10 then there is between BlackBerry 7.0 and the PlayBook OS, so my assumption was not completely wrong. That said, the introduction of the Cascades UI acquired with The Astonishing Tribe is a major change. Lejune told me that Cascades UI will be in effect the native UI of BlackBerry 10, and the built-in apps will use it.

The first version of the PlayBook uses both native code and Adobe AIR for its built-in apps.

RIM has given full backing to Adobe AIR at this event, presenting it as one of the supported development platforms and saying that it will support AIR for as long as Adobe does and maybe even longer. Even so, it would be fair to say that RIM is moving away from AIR and towards native code and Cascades UI in BlackBerry 10.

Further, Adobe itself has changed direction since the launch of the PlayBook last year. Adobe has made it clear that while Flash, Flex and AIR are still important, its strategic direction is HTML 5 when it comes to development platforms. Some aspects of Flex, the code-based approach to AIR authoring, are being wound down, including the visual designer in Flash Builder.

My sense therefore is that AIR is not the best choice if you are considering how to develop for BlackBerry 10 – and BlackBerry 10 is the future of RIM’s platform. The primary choice should be between Cascades UI, for best performance and integration, or WebWorks (PhoneGap), for development in HTML and JavaScript and cross-platform code.

Will Nokia’s Qt come to Windows Phone?

tim — Tue, 07 Feb 2012 15:51:06 +0000

When Nokia acquired Trolltech back in 2008, it made perfect sense as a way of supporting development on Symbian, its smartphone operating system, and nudging the Qt project, which provides a cross-platform framework for native applications, more towards mobile rather than just desktop application support. It also made sense as Nokia worked on Maemo and then Meego, its Linux for mobile project.

Then came February 2011 and CEO Stephen Elop’s announcement that Nokia would partner with Microsoft and make Windows Phone its primary smartphone operating system. Windows Phone 7 does not support native code development, other than by operators, manufacturers, and of course Microsoft itself. What future for Qt at Nokia now?

Here at Blackberry Devcon Europe, Nokia’s Lars Knoll, Qt Chief Maintainer, has been introducing Qt to Blackberry developers. Qt forms a critical part of RIM’s Blackberry 10 (BBX) platform, based on the PlayBook tablet OS and set to come to Blackberry phones later this year. The Cascades UI framework, for hardware-accelerated 2D and 3D rendering on BBX, uses Qt core and an adaption of QML (Qt Modeling Language). You can use Qt with or without Cascades on BBX.

Given that Nokia makes mobile devices which are in competition with RIM’s devices, it may seem odd that Nokia is supporting Qt on Blackberry. I asked Knoll about the status of Qt within Nokia following the move to Windows Phone.

There’s not too much I can say right now. The only thing I can repeat is that we’re still investing in Qt. We’re actually hiring more people to work on Qt. Qt is an essential part of the strategy for the next billion. That’s all I can say right now, but stay tuned, in time you’ll hear more.

He added later that Nokia is in business to make money; in other words, there are strong business reasons for Nokia to continue with Qt. The “next billion” reference refers to Nokia’s stated intention to bring apps to the next billion.

One possibility is that Qt will in fact support a future version of Windows Phone. It is already clear that Windows Phone 8 will use the same kernel as Windows 8 and we can expect a unified development platform build on the Windows Runtime (WinRT), which does support native code development.

It is not too much of a stretch then to expect a future Qt framework that will target Windows Phone and Windows 8 tablets. Nokia’s Elop has also hinted that it is interested in Windows tablets as well as phones in future.

Telcos have a dying business model – APIs and cloud services are the future says Alcatel-Lucent’s Laura Merling

tim — Fri, 03 Feb 2012 13:38:31 +0000

Laura Merling from Alcatel-Lucent spoke at the Monki Gras conference in London earlier this week, saying in effect that telecommunication companies have a dying business model.

She gave a two-minute summary of Telco history. “First it was all about voice,” she said. “Then the intertubes happened. Now you had data … then it went back to voice, the big push for wireless. Then of course wireless moved, so it’s not about voice any more, it’s about the data.”

She expects the next step to be “connected devices … the phone goes away, everything you do both data and voice happens on other devices.”

What does this mean for telcos? They have become commoditised, she said, suppliers of data plans. “It is a big commoditised business that has no real innovation.”

“In the future, the data plans dies,”, Merling says. “Think about it. How many devices have you got? Think about connecting all of those. You probably want the same data plan. But why pay for a data plan? How will telcos make money? You can’t just keep increasing the data plan.”

Instead, the money is going to come from the APIs and accessing the services.

Enter Twilio, a virtual telco. “I think of twilio as a craft telco”, said Merling, tying in with the beer theme that flowed through Monki Gras. “Do they sell hardware? No. They have software and APIs.” She says the Twilio business model scares the industry: it is based on transactions, not data plans. She also noted how old established vendors are buying up software-based providers, such as BT acquiring Ribbit and Microsoft acquiring Skype.

Tomorrow’s telco, says Merling, is a based on a software stack. “Antennas and towers are not going to go away, but the infrastructure becomes all software based … combining network services with cloud infrastructure.

“At Alcatel-Lucent we sell hardware. We sell big giant boxes. But this is where it is going.” She says the telcos are now aware of this, hence the title of her session “How telcos got API religion.”

Her final prediction? “Jeff Lawson becomes the CEO of AT&T. Why? Because the model has to change.”

It was a thought-provoking talk, though the unspoken question was whether in fact the telcos will successfully transition or whether they will simply become less important, continuing to maintain the pipes while others profit from what flows through them.

I interviewed Twilio CEO Jeff Lawson in October last year.

Windows Phone 8 “Apollo”: Windows 8 kernel, more form factors

tim — Thu, 02 Feb 2012 22:38:00 +0000

Microsoft’s partner ecosystem is vulnerable to leaks, as demonstrated today by reports of a video said to have been made for Nokia, which arrived in the hands of a smartphone review website. The leaked information was corroborated by Windows journalist Paul Thurrott who has received advance information independently from Microsoft, but under non-disclosure:

Thanks to a recent leak which has revealed some interesting information about the next major Windows Phone version, I can now publicly discuss Windows Phone 8 for the first time.

First, a quick recap:

Windows Phone 7.5 “Mango” came out in the second half of last year and was the launch OS for Nokia’s Lumia phones.
Windows Phone “Tango” is expected in the second quarter of 2012 and appears to be a minor update focused on low-end handsets.
Windows Phone “Apollo” is the subject of the new leaks. Some of the details:
Uses the Windows 8 kernel and other OS components, rather than Windows CE
Supports multicore processors
Supports more form factors and screen resolutions
Preserves compatibility with Windows Phone 7 apps
Adds BitLocker encryption

I presume this also means that native code development will be supported, as it is for the Windows Runtime (WinRT) in Windows 8.

Date for “Apollo”? The rumour is towards the end of this year, as a close follow-on from Windows 8 itself.

Like many leaks, this one raises as many questions as it answers. While it makes sense that Windows Phone 8 and Windows 8 should share the same kernel, it also raises the question of how they are differentiated. Windows 8, especially on ARM, is designed for small screens and tablets. Windows Phone 8, we now learn, will support more form factors. The implication is that there may be Windows Phone 8 devices that are close in size to Windows 8 devices. Will they run the same apps from the same Marketplace, at least in some cases, in the same way that some iOS apps support both iPhone and iPad?

The Windows 8 and Windows Phone 8 era will be simplified in one sense, with a single core operating system across desktop and devices. In another sense though, it ushers in new complexity, with multiple platforms that have subtle or not so subtle differences:

Windows 8 desktop side, on laptop and tablet (x86)
Windows 8 desktop side, laptop and tablet (ARM) – rumoured to be locked down for Office and perhaps a few other favoured apps
Windows 8 Metro side, desktop, laptop and tablet (x86) which should be nearly the same as
Windows 8 Metro side, desktop, laptop and tablet (ARM) – runs WinRT
Windows Phone 8 – runs WinRT, plus Silverlight compatibility layer

My guess is that Microsoft will push WinRT as the single platform developers should target, but I can see scope for confusion among both developers and users.

What would you like to see in Microsoft Office 15?

tim — Mon, 30 Jan 2012 18:02:50 +0000

Today brings the news that Microsoft Office 15 is now in Technical Preview (also known as private beta).

There is little news about what is in it other than this:

With Office 15, for the first time ever, we will simultaneously update our cloud services, servers, and mobile and PC clients for Office, Office 365, Exchange, SharePoint, Lync, Project, and Visio.

So what would you like to see in Office 15? Here are a few things on my wish list:

Properly integrate SharePoint (and therefore Office 365) with Windows so that you can use it easily without ever opening a web browser. That might mean fixing SharePoint WorkSpace or doing something better, like Explorer integration without the various hassles associated with WebDAV.
Fix Outlook, or better still replace it. I hear many complaints about Outlook, either concerning its performance, or else one of its many annoyances such as how hard it is to reply to an email while quoting sections of the original message – astonishing, when you consider the maturity of the product.
Improve cross-platform support. Office on the Mac is poor compared to the Windows version, particularly in terms of performance. It is also time Microsoft came out with apps for iOS and Android for touch-friendly document editing.
Update the user interface for touch control as far as possible. This will be critical for Windows 8 tablets, especially on ARM.
Improve structured document editing in Word. Styles are hard to use, so are bullets and numbering. I tend not to use the paragraph numbering in Word because it is so fiddly and annoying.

The problem is that Office is a huge and intricate bag of legacy. The work Microsoft did in replacing the menus with ribbon toolbars was admirable in its way, and potentially more touch-friendly, but if you scratch the surface much is unchanged underneath. All the old commands remain.

Nokia results: hope for Windows Phone?

tim — Thu, 26 Jan 2012 13:53:56 +0000

It is almost one year since Nokia’s dramatic announcement that it would transition its smartphone range to Windows Phone. Today the company released its results for the fourth quarter and for the full year 2011, the first since the release of the the Lumia range of Windows Phone devices. How it is doing?

This is one you can spin either way. The negative view: Nokia is losing money. Sales are down 21% year on year for the quarter and 9% for the full year, and the company reported an operating loss of just over a billion Euro for the year, most of which was in the last quarter.

If you look at the quarter on quarter device sales, they are down in both smart devices and mobile phones. The Symbian business has not held up as well as the company hoped:

changing market conditions are putting increased pressure on Symbian. In certain markets, there has been an acceleration of the anticipated trend towards lower-priced smartphones with specifications that are different from Symbian’s traditional strengths. As a result of the changing market conditions, combined with our increased focus on Lumia, we now believe that we will sell fewer Symbian devices than we previously anticipated.

says the press release. As for Windows Phone and Lumia, CEO Stephen Elop says that “well over 1 million Lumia devices” have been sold: a start, but still tiny relative to Apple iOS and Google Android. Elop cleverly calls it a “beachhead”, but given the energy Nokia put into the launch I suspect it is disappointed with the numbers.

Put this in context though and there are reasons for hope. First, Nokia’s speed of execution is impressive, from announcement to the first Windows Phones in nine months or so. Further, the Lumia (judging by the Lumia 800 I have been using) does not feel like a device rushed to market. The design is excellent, and within the small world of Windows Phone 7 hardware Nokia has established itself as the brand of first choice.

Second, despite the dismal sales for Windows Phone 7 since its launch, there are signs that Microsoft may yet emerge from the wreckage inflicted on the market by iOS and Android in better shape than others. WebOS has all-but gone. RIM has yet to convince us that it has a viable recovery strategy. Intel Tizen is just getting started. If Microsoft has a successful launch for Windows 8, Elop’s “third ecosystem” idea may yet come to fruition.

Third, Nokia has already shown that it is better able to market Windows Phone 7 than Microsoft itself, or its other mobile partners. Lumia made a good splash at CES in January, and the platform may gain some market share in the influential US market.

Nokia is not just Windows Phone though, and even if its smartphone strategy starts to work it has those falling Symbian sales to contend with. It will not be easy, even taking an optimistic view.

Nor will it be easy for Windows 8 to succeed in a tablet market owned by Apple at the high end and by Amazon/Android at the low end.

Appcelerator CEO on EMEA expansion, Titanium vs PhoneGap, and how WebKit drives HTML5 standards

tim — Thu, 19 Jan 2012 11:40:55 +0000

I spoke to Appcelerator CEO Jeff Haynie yesterday, just before today’s announcement of the opening of an EMEA headquarters in Reading. It has only 4 or 5 staff at the moment, mostly sales and marketing, but will expand into professional services and training.

Appcelerator’s product is a cross-platform (though see below) development platform for both desktop and mobile applications. The mobile aspect makes this a hot market to be in, and the company says it has annual growth of several hundred percent. “We’re not profitable yet, but we’ve got about 1300 customers now,” Haynie told me. “ On the developer numbers side, we’ve got about 235,000 mobile developers and about 35,000 apps that have been built.”

In November 2011, Red Hat invested in Appcelerator and announced a partnership based on using Titanium with OpenShift, Red Hat’s cloud platform.

Another cross-platform mobile toolkit is PhoneGap, which has received lots of attention following the acquisition of Nitobi, the company which built PhoneGap, by Adobe, and also the donation of PhoneGap to the Apache Foundation. I asked Haynie to explain how Titanium’s approach differs from that of PhoneGap.

Technically what we do and what PhoneGap does is a lot different. PhoneGap is about how do you take HTML and wrap it into a web browser and put it into a native container and expose some of the basic APIs. Titanium is really about how you expose JavaScript for an API for native capabilities, and have you build a real native application or an HTML5 application. We offer both a true native application – I mean the UI is native and you get full access to all the API as if you had written it native, but you are writing it in JavaScript. We have also got now an HTML5 product where that same codebase can be deployed into an HTML5 web-driven interface. We think that is wildly different technically and delivers a much better application.

Haynie agrees that cross-platform tools can compromise performance and design, and even resists placing Titanium in the cross-platform category:

Titanium is a real native UI. When you’re in an iPhone TableView it’s actually a real native TableView, not an HTML5 table that happens to look like a TableView. You get the best of both worlds. You get a JavaScript-driven, web-driven API, but when you actually create the app you get a real app. Then we have an open extensible API so it’s really easy if you want to expose additional capabilities or bring in third-party libraries, very similar to what you do in Java with JNI [Java Native Invocation].

The category has got a bit of a bad rap. We wouldn’t really describe ourselves as cross-platform. We’re really an API that allows you target multiple different devices. It’s not a write-once run anywhere, it’s really API driven.

80% of our core APIs are meant to be portable. Filesystems, threads, things like that. Even some of the UI layer, basic views and buttons and things like that. But then you have a Titanium iOS namespace [for example] which allows you to access all the iOS-specific APIs, that aren’t portable.

I asked Haynie for his perspective on the mobile platform wars. Apple and Android dominate, but what about the others?

RIM and Microsoft are fighting for third place. I would go long on Microsoft. Look at Xbox, look at the impact of long-term endeavours, they have the sustainability and the investment power to play the long game, especially in the enterprise. We’ll see Microsoft make significant strides in Windows 8 and beyond.

Even within Android, there are going to be a lot of different types of Android that will be both complementary and competitive with Google. They will continue to take the lion’s share of the market. Apple will be a smaller but highly profitable and vertically integrated ecosystem. In my opinion Microsoft is a bit of bridge between both. They’re more open than Apple, and more vertically integrated than Google, with tighter standardisation and stacks.

I wouldn’t quite count RIM out. They still have a decent market share, especially in certain parts of the world and certain types of application. But they’ve got a long way to go with their new platform.

So will Titanium support Windows 8 “Metro” apps, running on the new WinRT runtime?

Yes, we don’t have a date or anything to announce, but yes.

I was also interested in his thoughts on Adobe, particularly as there is some flow of employees from Adobe to Appcelerator. Is he seeing migration of developers from Flex, Flash and AIR to Titanium?

Adobe has had a tremendously successful product in Flash, the web wouldn’t be the web today if it wasn’t for Flash, but the advent of HTML5 is encroaching on that. How do they move to the next big thing, I don’t know if they have a next big thing? And they’re dealing in an ecosystem that’s not necessarily level ground. That’s churning lots of dissenting and different opinions inside Adobe, is what we’re hearing.

We’re seeing a large degree of people that are Flash, ActionScript oriented that are migrating. We’ve hired a number of people from Adobe. Quite a lot of people in our QA group actually came out of the Adobe AIR group. Adobe is a fantastic company, the question is what’s their future and what’s their plan?

FInally, we discussed web standards. With a product that depends on web technology, does Appcelerator get involved in the HTML5 standards process? The question prompted an intriguing response with regard to WebKit, the open source browser engine.

We’re heavily involved in the Eclipse foundation, but not in the W3C today. I spent about 3 and half years on the W3C in my last company, so I’m familiar with the process and the people. The W3C process is largely driven – and I know the PhoneGap people have tried to get involved – by the WHAT working group and the HTML5 working group, which ultimately are driven by the browser manufacturers … it’s a largely vendor-oriented, fragmented space right now, that’s the challenge. We still haven’t managed to get a royalty-free, IPR-free codec for video.

I’d also say that one of the biggest factors pushing HTML5 is less the standardisation itself and more WebKit. WebKit has become the de facto [standard], which has really been driven by Apple and Google and against Microsoft. That’s driving HTML5 forward as much as the working group itself.

Asus Transformer Prime update: Google video rental or unlocked bootloader, you choose

tim — Tue, 03 Jan 2012 19:14:38 +0000

Asus has responded to demands for an unlocked bootloader for its its latest Transformer Prime tablet.

It turns out that DRM is the culprit – at least, that is what Asus says on its Facebook page:

Regarding the bootloader, the reason we chose to lock it is due to content providers’ requirement for DRM client devices to be as secure as possible. ASUS supports Google DRM in order to provide users with a high quality video rental experience. Also, based on our experience, users who choose to root their devices risk breaking the system completely. However, we know there is demand in the modding community to have an unlocked bootloader. Therefore, ASUS is developing an unlock tool for that community. Please do note that if you choose to unlock your device, the ASUS warranty will be void, and Google video rental will also be unavailable because the device will be no longer protected by security mechanism.

My guess is that most modders will cheerfully unlock their bootloaders and ditch the DRM. That said, I am not clear why this should void the warranty unless it is software related.

Users petition Asus over locked bootloader in Asus Transformer Prime

tim — Tue, 03 Jan 2012 09:32:06 +0000

The new Asus Transformer Prime TF201 Android tablet is winning praise for its performance and flexibility. It is driven by NVIDIA’s quad-core Tegra 3 processor and can be equipped with a keyboard and dock that extends battery life and makes the device more like a laptop.

All good; but techie users are upset that the bootloader is encrypted, which means the kernel cannot be modified other than through official Asus updates.

A petition on the subject has achieved over 2000 signatures. Detailed discussion of the implications are here.

Why do vendors lock the bootloader? One reason is for support, since it increases the user’s ability to mess up their machines. On the other hand, most users who hack to this extent understand what they are doing. This comment from the petition stood out for me:

We understand that custom firmware cannot be supported by ASUS, but we consider that it is our right to customise our devices in any way we wish: once bought, the Prime is our property alone to modify if we choose.

This is something we have taken for granted in the PC era, but the tablet era is looking different, with locked-down devices that give vendors more control. The success of the Apple iPad suggests that most users do not mind if the result is a good experience. It is a profound change though, and one that makes users vulnerable to vendors who are slow or reluctant to provide updates.
