Bill Buxton, Windows Phone 7 hits at Mix10, say attendees

I recall seeing conversations on Twitter about whether it is worth going to conferences, especially vendor-led ones such as Microsoft’s Mix10 which took place earlier this month. It’s expensive, it’s marketing, and many of the sessions are available for free online soon after they take place.

In that context it’s interesting to see some off-the-cuff comments from attendees about what they liked at Mix. Networking comes high on the list, something you cannot get from a distance. There is general boredom with slide-driven presentations, and enthusiasm for interactive panels. One attendee says:

I always find the panels more exciting, and I like the open dialogs where people can ask questions and get real world opinion and advice

As for the content, the name that comes up most often is Bill Buxton, the design expert who joined Microsoft specifically to introduce greater design-consciousness into a company whose track record in this respect is poor. It was a fascinating appointment, and I believe you can see traces of his work in Windows 7 and much more in Windows Phone 7. I talked to Buxton briefly about this and wrote it up here. When I say “his work”, I don’t mean hands-on screen designs, rather a different approach to product development.

Buxton apparently made a considerable impression at Mix10. His session An hour with Bill Buxton (the link has the video) is also one that is interactive, and worth watching if you have an interest in where design fits into the development process. The fact that Microsoft-platform developers are engaging with his ideas is encouraging, given the usability issues that spoil so many Windows applications and machines.

Overall it also seems that Windows Phone 7 went down well – remarkable when you consider that Windows Mobile was all-but dismissed as irrelevant a few months ago – though I did smile at the Microsoft employee (I think) who shows an iPhone with a Mix scheduling app installed. Its special feature: shake the iPhone and it displays a Windows Phone 7 screen, handy if Ballmer appears in the corridor:

One final point: an attendee says IronRuby was shown running on Windows Phone 7 in one of the sessions, something I was told elsewhere was not possible.

Adobe news: Flash Builder 4, Creative Suite 5, quarterly results

Lots of Adobe news this week.

First, the release of Flash Builder 4. It seems a long time ago that I was looking at the first preview of code-name Gumbo; it’s good to see this finally released. Since it is Eclipse-based, it looks similar to to Flex Builder 3.0; but under the covers there is the new Flex 4 SDK with the Spark component architecture. The design tools have been revamped, and a time-saving feature is that you can now generate an event handler with one click. Flash Builder 4 also has built-in unit testing with FlexUnit, which is a big deal for those enlightened folk who do test-driven development.

Adobe has also worked hard on database connectivity. Flash Builder 4 will generate wrapper code for a variety of data sources, including HTTP and REST, PHP, SOAP, and Adobe’s LiveCycle Data Services middleware.

There is a new data/services panel that shows all the available sources, with drag-and-drop data binding, batch updates, and other handy features.

There are a few downsides to Flash Builder 4. ActionScript feels dated if you have been playing with something like C# 4.0, soon to be released as part of Microsoft’s Visual Studio 2010. I’ve also heard complaints that equivalent projects built with Flex are larger than equivalents built with the Flash IDE. The naming is puzzling; we now have to distinguish between the Flash IDE and the Flash Builder IDE, which are completely different products, but the SDK for code-centric development is still called Flex. There is no support yet for AIR 2.0, the latest version of the desktop runtime; nor for the much-hyped iPhone app development. Patience is called for, I guess.

More information on Flex and Flash Builder here.

The next big product launch from Adobe will be Creative Suite 5, for which a launch date of Monday, 12th April has been announced. You can sign up for an online launch event and see some sneak peek videos here.

Finally, Adobe released quarterly financial figures today. The company says they are strong results; revenue is 9.1% higher than last year and GAAP earnings are positive (unlike the last quarter). However, looking at the investor datasheet [PDF] I noticed that new analytics acquisition Omniture now accounts for 10% of revenue; if you deduct that from the increase it does not look so good. Still, a profit is a profit, and the quarter before a major update to CS 5.0 may be under par as users wait for the new release,  so overall it does not look too bad.  The Q1 Earnings Call is worth looking at if only for its nice indexing; I wish all online videos worked like this.

One questioner asked about HTML 5 – “how quickly can you provide support when it comes”? An intriguing question. I suspect it reflects more on the publicity around Flash vs HTML than on the progress of the HTML 5 standard itself, which is coming in fits and starts. “The reality is that it’s a fragmented standard, but we will continue to support it”, was the answer from CEO Shantanu Narayen, though he added a plug for the “benefits of our runtime, which is Flash”.

UK government’s open source commitment words not deeds says Ingres VP

UK Prime Minister Gordon Brown spoke today about the government’s IT strategy, including a mention for how open source technology can reduce costs:

… we will unleash data and content to the community to turn into applications that meet genuine needs. This does not require large-scale government IT Infrastructure; the ‘open source’ technology that will make it happen is freely available. All that is required is the will and willingness of the centre to give up control.

A naïve statement: “IT Infrastructure” normally refers to hardware as well as software. Hardware is not “freely available”; and even in cases where free open source software is used, the management and software development effort does not come for free either.

The closest thing to free IT infrastructure is something like Google Apps, which is not open source, but subsidised by advertising alongside Google’s confidence that it can make money somehow if you commit to its platform.

Still, leaving that aside, it is good to hear that the UK government recognises the benefits of open source. Or does it? Steve Shine, executive VP of worldwide operations at the open source database vendor Ingres, is sceptical:

This is not the first time such platitudes have been made by the government.  Over the past 12 months the office of the CIO has continually pointed to open source as the key to reducing capital expenditure on large public sector IT projects.  We at Ingres work with public sector bodies daily and have not seen the enforcement of these policies at a practical level and so view this announcement cautiously.   Right now there is a very large negotiation underway to renew Oracle’s contract with the MOD which in theory should be put to competitive tender but sadly is being conducted behind closed doors.

We therefore urge the government to enforce the ideas put forward today: Put steps in place to open up the public sector IT procurement process, run tenders in public and put penalties in place for those bodies that fail to assess open source software.

Ingres has a direct commercial interest in this, of course, so such statements are not surprising. Shine has a point though. It takes more than a few speeches to change the software culture of the myriad departments and other state-run entities that between them compose government IT.

Google’s privacy campaign, and three ways in which Google gets your data

7 Comments

Google is campaigning to reassure us that its Chrome browser is, well, no worse at recording your every move on the web than any other browser.

Using Chrome doesn’t mean sharing more information with Google than using any other browser

says a spokesman in this video, part of a series on Google Chrome & Privacy.

image

What then follows is links to four other videos describing the various ways in which Google Chrome records your web activity.

If you subtract the spin, the conclusion is that Google retrieves a large amount of data from you, especially if you stick with the default settings. Further, it is not possible as far as I know to use the browser without sending any data to your default search provider, most likely Google. The reason is the Omnibox, the combined address and search box. Here’s what Google’s Brian Rakowski says in the video on Google Chrome & Privacy – Browsers search and suggestions

For combined search and web address to work, input in the Omnibox will need to be sent to your search provider to return suggestions. If you have chosen Google as your search provider, only around 2% of the search input is logged and used to improve Google’s suggestion service. Rest assured that this data is anonymised as soon as possible within 24 hours, and you always have the option of disabling the suggest feature at any time.

However, even if you disable suggestions, what you type in the box still gets sent to your search provider if it is not a valid web address, in other words anything that is not a complete URL (though Chrome will infer the http:// prefix).

It is also worth noting that Google does not only get your data via browser features. Most web pages today are not served from a single source. They include scripts that serve data from other locations, which means that your browser requests it, which means that these other locations know your IP number, browser version and so on. Two of the most common sources for such scripts are Google AdSense (for advertising) and Google Analytics (for analysing web traffic).

Even if you contrive not to tell Google in advance where you are going, it will probably find out when you get there.

It is important to distinguish what Google can do from what it does do. Note the language in Rakowski’s explanation above. When he says input is sent to your search provider, he is describing the technology. When he says that data is anonymized as soon as possible, he is asking us to trust Google.

Note also that if you ask to send in auditors to verify that Google is successfully anonymising your data, it is likely that your request will be refused.

There are ways round all these things, but most of us have to accept that Google is getting more than enough data from us to create a detailed profile. Therefore the secondary question, of how trustworthy the company is, matters more than the first one, about how it gets the data.

Windows Phone 7 emulator yields its secrets

1 Comment

So that didn’t take long. Microsoft has made a Windows Phone 7 emulator available to all, explaining that it is a virtual machine running the real device OS. While it works fine for debugging applications, most of the phone UI is mysteriously absent, the exception being Internet Explorer (needed for testing web applications). However, Dan Ardelean has done some nifty work with the emulator image, discovering that a lot more of the UI is present and can be exposed if you make a few modifications. He posted his modified ROM but has since removed it because of copyright concerns. I doubt it will be hard to find.

image

Applications available in the hacked emulator include Mobile Office with Word, Excel, PowerPoint, OneNote and Sharepoint Workspace (undermining Microsoft’s claim that this is only a consumer device), games including a version of Times Reader – full circle for this one, which started out in WPF, moved to Silverlight for Mac, deserted and went to Adobe Flash, and may now reappear in Silverlight – and music/video via a Zune section.

image

My tip to Microsoft: if you don’t want these things to leak, best not put them in the publicly-available image.

Ardelean has also figured out how to amend the native C# port of SQLite, satisfying demand for a local SQL database engine. SQL Server Compact Edition is actually present in Windows Phone 7, but not available to custom applications.

Visual Studio software factories to emerge from Microsoft deep freeze

Last night at the Microsoft Mix party in Las Vegas I happened across Michael Lehman, a senior architect, who told me he had been working for the last six years on a Visual Studio add-on called Feature Builder. This turns out to be the evolution of the very same project which Microsoft’s Jack Greenfield told me about back in March 2007, at an architecture conference in the UK, though back then it had a more exalted status (in Greenfield’s eyes at least) – he described it as a platform rather than merely an add-on. Now Feature Builder is to appear as an extension in the Visual Studio 2010 Gallery, only discoverable by those who seek it out. If enough developers find it and like it, it may end up as part of a future Visual Studio release.

It’s all part of Microsoft’s desperately confused architecture and modelling story. Note that Greenfield in 2007 denigrated the UML:

The UML is a collection of useful abstractions. Unfortunately it’s been peddled as a universal modelling language, but the U never stood for Universal. We subscribe to Michael Jackson, author of Problem Frames, who says that there is no such thing as a universal solution. It’s a childish approach. This is where the Universal Modelling Language marketing pitch fails. UML was never properly extensible. It also has the problem that it was designed by a committee.

So what do we have actually shipping with Visual Studio 2010? Standard UML modelling, the best Microsoft has yet come up with.

Reading between the lines, this likely means that the UML faction within Microsoft outvoted the non-UML faction. However, each release of Visual Studio seems to have its own unique approach to modelling and architecture tools, so it would be no great surprise if Visual Studio 2012, say, replaced them with something different.

As for Feature Builder, it does sound interesting – read the Greenfield interview referenced above for why it has potential. Lehman says it is a simpler approach than previous software factory tools from Microsoft, and named Feature Builder to avoid association with past efforts.

Update: Lehman has blogged about the project here, and you can download the preview here.

Microsoft playing HTML 5 standards game alongside Silverlight game

1 Comment

I’m at Mix10 in Las Vegas where Microsoft has been showing off the latest preview of IE9 – you can try it here, provided you have Vista SP2, Windows 2008 or Windows 7.

The two themes are performance, with GPU-accelerated HTML and graphics and a new Javascript engine that compiles code in the background, and standards support. This latter was not a surprise to me, as I’d heard the well-informed Molly Holzschlag praise Microsoft’s commitment to HTML5 at a workshop here on Sunday – see this earlier post.

During the keynote, we saw IE9 playing a video using the HTML 5 video tag – no Flash or Silverlight needed. Microsoft also showed that in this instance IE9 performed better than Chrome thanks to better hardware acceleration. Although one should always mistrust one vendor’s demonstration of another vendor’s product, it should not be surprising that Microsoft is able to deliver a browser that is better optimised for Windows.

Video, hardware accelerated graphics, audio element support, fast JavaScript: there is considerable overlap with the features of the Microsoft Silverlight (and Adobe Flash) plug-ins.

The plug-in approach has advantages. It offers consistency across browsers, and enables rapid evolution without the hassles of standards committees. The multimedia features in Silverlight and Flash are well ahead of those in HTML 5 – Holzschlag nailed this when she described today’s HTML 5 demos as reminiscent of Flash demos a decade ago.

Still, if you can do without the plug-in you end up with cleaner code, removing the awkward transition between what is in HTML and JavaScript, and what is in the plug-in. There is also a better chance that your code will run on Apple’s iPhone and iPad, for example.

The question though: can Microsoft do an equally good job of supporting HTML 5 throughout its platform, as it will do with Silverlight? This is where I’m doubtful. The Visual Studio and Expression tools will continue to drive developers towards Silverlight rather than HTML 5.

It’s notable that shortly after Microsoft’s IE9 demos at Mix, we saw demos of fun technology like code-name Houston, develop databases in the cloud using just your browser and … Silverlight.

No native code development on Windows Phone 7 says Microsoft – so what about Flash?

9 Comments

Windows Phone 7 is a managed code platform, we’ve been told at Mix10 in Las Vegas. Development is via Silverlight or XNA; there is no native API.

Of course there is a native API; the question is more about what code is allowed to access it. Still, in the press briefing the spokesman was clear that native code development will not be supported.

What about projects like Adobe’s Flash runtime, which both Microsoft and Adobe have said is planned, or at least (in Microsoft’s case), not blocked – although we already know that Flash will not be available in the first release.

All my spokesman would say is that nothing has been announced about that.

My suspicion is that in reality certain privileged vendors will be able to, in effect, extend the operating system with native code libraries. Adobe could be one of those; so too could a company like Rhomobile, which has a cross-compiler for a variety of mobile platforms. So I doubt that Microsoft has yet given us the full story here.

Update: The latest on this is that Microsoft’s Charlie Kindel says that Adobe will have special native access for Flash, but that no other vendor will have that privilege. This still does not make sense to me. Let’s suppose that Windows Phone 7 is a big success. What justification could Microsoft have for supporting the Flash runtime but not the Java runtime, for example? I suspect that Microsoft is chasing the Flash checkbox to one-up Apple; but if Adobe gets native access, others will no doubt follow.

Microsoft copies Apple with Windows Phone app lock-in?

3 Comments

I’m reading the documentation for Windows Phone development. Here’s what it says:

A set of tools will help the developer to submit and certify their applications for the Windows Phone Marketplace. Applications are submitted in a .XAP file format, which is essentially one compressed file that contains all the files that are needed by the application. Developers can track their submission status and then receive a notification once the certification is complete. After an application is certified, it can then be submitted for publishing on the Windows Phone Marketplace. Developers can set pricing and select the markets in which they wish to publish the application.

Application updates can go through the certification and publishing process again in order to fix bugs, add new functionality, or provide whole new versions.

Windows Phone Marketplace and Billing

The Windows Phone Marketplace provides the one place where developers can make their applications available for purchase by consumers. Both Mobile Operator and credit card billing are supported, making it as easy as possible for consumers to pay for the program.

Note the lock-in words: apps must be certified by Microsoft, and the Windows Phone Marketplace is the “one place” to make applications available for purchase. According to Microsoft’s Charlie Kindel, Microsoft will take 30% of all revenue, and in most cases there is also a fee for registering as a Marketplace vendor.

I understand Microsoft’s Apple-envy; but it is disappointing to find that this new platform is equally locked, if I’m reading this correctly.

Windows Phone 7 developer story unveiled at Mix10

1 Comment

I’m in Las Vegas for Microsoft’s Mix10 conference, where the developer story for Windows Phone 7 series is being unveiled. According to the press release, the tooling for Windows Phone 7 looks like this:

  • Visual Studio 2010 Express for Windows Phone (free)
  • Windows Phone 7 Series add-in for Visual Studio 2010 RC
  • XNA Game Studio 4.0
  • Emulator
  • Expression Blend for Win Phone CTP

Essentially, you are meant to use XNA for games on the device, and Silverlight for other kinds of application.

Another part of the announcement describes new services for developers – Microsoft Location Service to provide location information, and a notification service to “push information to the phone, regardless of whether or not an application is running”.

Applications will be marketed through a new Windows Phone Marketplace.

I’ll report more details as they emerge, here and on The Register.

Update: Microsoft has added that Expression Blend 4.0, for Silverlight 4.0 support, will be a free upgrade from Expression Blend 3.0.

Silverlight 4.0 RC, Expression Blend 4.0 beta, VS 2010 add-in available for download here: http://silverlight.net/getstarted/silverlight-4-beta/ 

The MSDN documentation for Windows Phone 7 is here: http://msdn.microsoft.com/en-us/library/ff402531(VS.92).aspx
