Reports of 19% decline in Western European PC market show structural change

4 Comments

As if we needed telling, a new Gartner report shows a steep decline in the PC market in Western Europe. A “PC” in this context includes Macs but excludes smartphones and what Gartner called “media tablets”, mostly Apple iPads. A few figures comparing shipments in the second quarter 2011 with the same period in 2010:

  • Total PC sales down 18.9%
  • Netbook sales down 53%
  • Desktop PCs down 15.4%
  • Apple up 0.5%
  • Consumer PC market down 27%

What interests me here is not so much the normal ebbing and flowing of the PC market, but structural change indicating a switch away from PCs and laptops to more lightweight mobile devices. I believe this is evidence of that, though the economy is weak and extending the life of existing PCs is an obvious saving both for businesses and consumers.

Still, the dramatic decline in netbook sales suggests that consumers really are buying the more expensive iPad in preference. If you believe that consumers are to some extent ahead of business in their technology choices, then we can expect more of the same in the corporate market too.

No doubt alarm bells have been ringing in Microsoft’s Redmond headquarters for some time. The company is betting on Windows 8 to rescue its operating system from permanent decline, which is why next month’s BUILD conference is so critical. Nevertheless, it will be a year or so before we get new-style tablets running Windows 8, so will it be too late? I tend to think not, just because of the strength of Microsoft in the business world and the importance of Windows for existing applications, but it is interesting to speculate.

One factor which you can argue either way, in terms of Microsoft’s prospects, is that non-iPad tablets seem to be struggling. HP’s TouchPad and RIM’s PlayBook seem to be selling poorly. Google Android looks more hopeful though overshadowed by legal concerns from multiple sources. In Australia and parts of Europe Apple has successfully barred or delayed sales of Samsung’s Galaxy Tab 10.1, though the latest news is that the ban has been lifted outside Germany.

Google is now a hardware company as it announces acquisition of Motorola Mobility and its patents

6 Comments

Google is to acquire Motorola Mobility, a major manufacturer of Android handsets. Why? I believe this is the key statement:

We recently explained how companies including Microsoft and Apple are banding together in anti-competitive patent attacks on Android. The U.S. Department of Justice had to intervene in the results of one recent patent auction to “protect competition and innovation in the open source software community” and it is currently looking into the results of the Nortel auction. Our acquisition of Motorola will increase competition by strengthening Google’s patent portfolio, which will enable us to better protect Android from anti-competitive threats from Microsoft, Apple and other companies.

What are the implications? This will assist Google in the patent wars and perhaps give it some of the benefits of vertical integration enjoyed by Apple with iOS; though this last is a difficult point. The more Google invests in Google Motorola, the more it will upset other Android partners. Google CEO Larry Page says:

This acquisition will not change our commitment to run Android as an open platform. Motorola will remain a licensee of Android and Android will remain open. We will run Motorola as a separate business.

It is unlikely to be so simple; and the main winner I foresee from today’s announcement is Microsoft. Nokia’s decision to embrace Windows Phone rather than Android looks smarter today, since for all its faults Microsoft has a history of working with multiple hardware vendors. The faltering launches of HP’s TouchPad and RIM’s PlayBook have also worked in Microsoft’s favour. I do not mean to understate Microsoft’s challenge in competing with Apple and Android, but I believe it has a better chance than either HP or RIM, thanks to its size and existing market penetration with Windows.

Microsoft will be clarifying its mobile and slate strategy next month at the BUILD conference.

Today’s announcement is also a sign that Google takes Android’s patent problems seriously, as indeed it should. The company’s policy of act first, seek forgiveness later seems to be unravelling. Oracle has a lawsuit against Google with respect to use of Java in Android that looks like it will run and run. FOSS patent expert Florian Mueller argues today that Android also infringes the Linux license, and that this is a problem that cannot easily be fixed. Samsung’s latest Galaxy Tab has been barred from the EU; not entirely a Google issue, but it runs Android.

Note of clarification: Google is acquiring Motorola Mobility, not the whole of Motorola. In January 2011 Motorola split into two businesses. Motorola Mobility is one, revenue in second quarter 2011 around $3.3 billion. The other is Motorola Solutions, revenue in second quarter 2011 around $2 billion.

C++ 11 is approved by ISO: a big day for native code development

4 Comments

Herb Sutter reports that C++ 0x, which will be called C++ 11, has been unanimously approved by the ISO C++ committee. The “11” in the name refers to the year of approval, 2011. The current standard is C++ 98, though amended as C++ 03, so it has taken 8 or 13 years to update it depending on how you count it.

This means that compiler makers can get on with implementing the full C++ 11 standard. Most current compilers implement some of the features already. This Apache wiki shows the current status. A quick glance suggests that the open source GCC is ahead of the pack, followed by Intel C++ and then perhaps Microsoft Visual C++.

C++ 11 is pretty much compatible with C++ 03 so existing code should still work. However there are many new features, enough for Bjarne Stroustrup to say in his feature summary:

Surprisingly, C++0x feels like a new language: The pieces just fit together better than they used to and I find a higher-level style of programming more natural than before and as efficient as ever. If you timidly approach C++ as just a better C or as an object-oriented language, you are going to miss the point. The abstractions are simply more flexible and affordable than before. Rely on the old mantra: If you think of it as a separate idea or object, represent it directly in the program; model real-world objects, and abstractions directly in code. It’s easier now.

Concurrent programming is better supported in C++ 11, important for getting the best performance from modern hardware.

It is curious how the programming landscape has changed in recent year. A few years back, you might have foreseen a day when most programming would be .NET, Java or JavaScript: all varieties of managed code. While those languages do still dominate, native code has come more to the fore, thanks to factors like Apple’s focus on Objective C, and signs of internal conflict at Microsoft over the best language for coding Windows applications.

That said, C++ 11 remains a demanding language to learn and use. As Stroustrup notes, since C++ 11 is a superset of C++ 98 it is technically harder to learn all of it, though new libraries and abstractions should help beginners. The reasons for using or not using C++ are not going to change significantly with this new standard.

Parallels Desktop 6 for Mac: nice work but beware Windows security settings

I’ve just set up Parallels Desktop 6 on a Mac, in preparation for some development work. Installed Parallels, created a new virtual machine, and selected a Windows 7 Professional with SP1 CD image downloaded from Microsoft’s excellent MSDN subscription service.

The way this works is that you install the Parallels application and the create a new virtual machine, selecting a boot CD or image. Next, you have a dialog where you select whether or not you want an Express installation. It is checked by default. I left it checked and proceeded with the install.

image

The setup was delightfully smooth and I was soon running Windows on the Mac. I chose a “Like my PC” install so that Windows runs in a window. The alternative is to hide the virtual Windows desktop and simply to show Windows applications on the Mac desktop.

Everything seemed fine, but I was puzzled. Why was Windows not installing any updates? It turns out that the Express install disables this setting.

image

It also sets user account control to an insecure setting, where the approval dialog does not use the secure desktop.

image

The Parallels Express install also sets up an Administrator account with a blank password, so you log on automatically.

No anti-virus is installed, which is not surprising since Windows does not come with anti-virus software by default.

These choices make a remarkable difference to the user experience. Set up was a pleasure and I could get to work straight away, untroubled by prompts, updates or warnings.

Unfortunately Windows in this state is insecure, and I am surprised that Parallels sets this as the default. Disabling automatic updates is particularly dangerous, leaving users at the mercy of any security issues that have been discovered since the install CD was built.

In mitigation, the Parallels user guide advises that you set a password after installation – but who reads user guides?

If you uncheck the Express Install option, you get a normal Windows installation with Microsoft’s defaults.

These security settings are unlikely to matter if you do not connect your Windows virtual machine to the internet, or if you never use a web browser or other Internet-connected software such as email clients. If you do real work in Windows though, which might well include Windows Outlook since the Mac version is poor in comparison, then I suggest changing the settings so that Window updates properly, as well as installing anti-virus software such as the free Security Essentials.

Charlie Kindel leaving Microsoft

3 Comments

Charlie Kindel, Windows Phone 7 developer champion at Microsoft, is leaving to start a new company, though he is vague about exactly what it will be:

Charlie will be staying in the Seattle area building a new tech company. The new company will be in stealth mode initially but involves advertising, mobile, cloud computing, and youth athletics.

says the press release.

He goes back a long way at Microsoft, 21 years to be precise. Among the accomplishments he claims:

  • Built ActiveX and DCOM
  • Shipped Internet Explorer 3.0
  • Drove the development of the home networking features in Windows XP
  • Founded eHome and shipped the first version of Windows Media Center
  • Drove the invention of Windows Smart Displays and Windows Media Center Extenders
  • Was the driving force behind Windows Home Server.

I remember IE 3.0 coming out. Surprising though it may seem today, it was an impressive achievement, though history has not been kind either to ActiveX or to DCOM.

Real-world Microsoft Team Foundation Server: Not very good, says ThoughtWorks

12 Comments

I spoke to Sam Newman, who is European Continuous Delivery Practice Lead at ThoughtWorks, a software development company. Needless to say, we talked extensively about Continuous Delivery and I will be reporting on this separately; but I was also interested in his comments on Microsoft’s Team Foundation Server (TFS).  He told me that ThoughtWorks teams often end up working with it at their .NET clients, but it is problematic. In one case, he said, 6% of productive time was absorbed dealing with TFS.

What was the problem, performance, bugs, features lacking?

When we’ve looked at the problems we’ve had, a lot of it unfortunately comes down to the version control system. It’s not very good. It’s slow, you can’t do rollbacks, sometimes things go missing, you get locks. When we talked about 6% of time, they were things like waiting for a solution to expand in Visual Studio. A lot of those issues are in the version control system.

A frustration is that you cannot use TFS with any version control system other than its own.

Every other build server in the world, from Anthill to Go to Cruise Control to Hudson, you can put in at least 10 version control systems. In TFS they are all coupled. So you can’t take the version control and point it at Subversion. That might resolve a lot of the issues.

Why is TFS so widely used? It is because it comes in the box, says Newman.

I can’t think of a single client that wanted a tool, went out into the marketplace, and selected TFS because it is the right tool for them. Most clients use TFS because it comes with their Enterprise MSDN licence.

I have tried TFS myself and found it pretty good; but then I am just testing it on small projects as a solo developer, so it is hard for me to replicate the experience of a real-world team. You would have thought that performance issues, such as waiting ages for a solution to expand in Visual Studio, could be solved by tracing the reason for the delay; but apparently this is not easy.

This is anecdotal evidence, and of course there may be plenty of TFS installations out there that work very well; I would be interested in hearing of counter examples. I am also not sure to what extent the problems apply to all versions of TFS, or whether there is improvement in TFS 2010.

Newman recognizes that anecdotal evidence is not much use: he says ThoughtWorks is trying to collect some solid data that can be used both to discuss with clients making version control and build system choices, and with Microsoft.

Performance is a feature, and makes a large contribution to user satisfaction. The first release of Outlook 2007 was extraordinarily slow in some setups, and I remember the pain of clicking on a folder and then waiting tapping my fingers while it thought about expanding. It sounds like some TFS users are having a similar experience but in Visual Studio.

GPU Programming for .NET: Tidepowerd’s GPU.NET gets some improvements, more needed

When I attended the 2010 GPU programming conference hosted by NVIDIA I encounted Tidepowerd, which has a .NET library called GPU.NET for GPU programming.

GPU programming enables amazing performance improvements for certain types of code. Most GPU programming is done in C/C++, but Typepowerd lets you run code in .NET, simply marking any methods you want to run on the GPU with a [kernel] attribute:

[Kernel]

private static void AddGpu(float[] a, float[] b, float[] c)
{
// Get the thread id and total number of threads
int ThreadId = BlockDimension.X * BlockIndex.X + ThreadIndex.X;
int TotalThreads = BlockDimension.X * GridDimension.X;
for (int ElementIndex = ThreadId; ElementIndex < a.Length; ElementIndex += TotalThreads)
{
c[ElementIndex] = a[ElementIndex] + b[ElementIndex];
}
}

GPU.NET is now at version 2.0 and includes Visual Studio Error List and IntelliSense support. This is useful, since some C# code will not run on the GPU. Strings, for example, are not supported. Take a look at this article which lists .NET OpCodes that do not work in GPU.NET.

GPU.NET requires an NVIDIA GPU with CUDA support and a CUDA 3.0 driver. It can run on Mac and Linux using Mono, the open source implementation of .NET. In principle, GPU.NET could also work with AMD GPUs or others via a vendor-specific runtime:

image

but the latest FAQ says:

Support for AMD devices is currently under development, and support for other hardware architectures will follow shortly.

Another limitation is support for multiple GPUs. If you want to do serious supercomputing relatively cheaply, stuffing a PC with a bunch of Tesla GPUs is a great way to do it, but currently GPU.NET only used one GPU per active thread as far as I can tell from this note:

The GPU.NET runtime includes a work-scheduling system which can distribute device method (“kernel”) calls to multiple GPUs in the system; at this time, this only works for applications which call device-based methods from multiple host threads using multiple CPU cores. In a future release, GPU.NET will be able to use multiple GPUs to execute a single method call.

I doubt that GPU.NET or other .NET libraries will ever compete with C/C++ for performance, but ease of use and productivity count for a lot too. Potentially GPU.NET could bring GPU programming to the broad range of .NET developers.

It is also worth checking out hoopoe’s CUDA.NET and OpenCL.NET which are free libraries. I have not done a detailed comparison but would be interested to hear from others who have.

Microsoft releases Visual Studio LightSwitch: a fascinating product with an uncertain future

8 Comments

Microsoft has released Visual Studio LightSwitch, a rapid application builder for data-centric applications.

image

LightSwitch builds Silverlight applications, which may seem strange bearing in mind that the future of Silverlight has been hotly debated since its lack of emphasis at the 2010 Professional Developers Conference. The explanation is either that Silverlight – or some close variant of Silverlight – has a more important future role than has yet been revealed; or that the developer division invented LightSwitch before Microsoft’s strategy shifted.

Either way, note that LightSwitch is a model-driven tool that is inherently well-suited to modification for different output types. If LightSwitch survives to version two, it would not surprise me to see other application targets appear. HTML 5 would make sense, as would Windows Phone.

So LightSwitch generates Silverlight applications, but they do not run on Windows Phone 7 which has Silverlight as its development platform? That is correct, and yes it does seem odd. I will give you the official line on this, which is that LightSwitch is not aimed primarily at developers, but is for business users who run Windows and who want a quick and easy way to build database applications. They will not care or even, supposedly, realise that they are building Silverlight apps.

I do not believe this is the whole story. It seems to me that either LightSwitch is a historical accident that will soon be quietly forgotten; or it is version one of a strategic product that will build multi-tier database applications, where the server is either Azure or on-premise, and the client any Windows device from phone to PC. Silverlight is ideal for this, with its modern presentation language (XAML), its sandboxed security, and its easy deployment. This last point is critical as we move into the app store era.

LightSwitch could be strategic then, or it could be a Microsoft muddle, since the official marketing line is unconvincing. I have spent considerable time with the beta and doubt that the supposed target market will get on with it well. Developers will also have a challenge, since the documentation is, apparently deliberately, incomplete when it comes to writing code. There is no complete reference, just lots of how-to examples that might or might not cover what you wish to achieve.

Nevertheless, there are flashes of brilliance in LightSwitch and I hope, perhaps vainly, that it does not get crushed under Microsoft’s HTML 5 steamroller. I set out some of its interesting features in a post nearly a year ago.

Put aside for a moment concerns about Silverlight and about Microsoft’s marketing strategy. The truth is that Microsoft is doing innovative work with database tools, not only in LightSwitch with its model-driven development but also in the SQL Server database projects and “Juneau” tools coming up for “Denali”, SQL Server 2011, which I covered briefly elsewhere. LightSwitch deserves a close look, even it is not clear yet why you would want actually to use it.

Living in an App Store world: what are the implications?

A few recent events prompt some reflections on the rise of app stores and the implications for developers and for the IT industry.

One is Apple’s OS X Lion release, available only through the Mac App Store; and the removal of the optical drive on the Mac Mini, making it hard to install shrink-wrap software.

Another is Adobe’s closure of its InMarket service and AIR Marketplace app store. Some app stores are doing better than others.

A third is TechCrunch reporting that book apps such as Nook and Kindle are being hobbled or removed from the Apple iOS store. While I cannot verify this at the moment – I still see the Kindle app in the store, and it still has a link to the Kindle web store – it is in tune with Apple’s announcement in February:

… publishers may no longer provide links in their apps (to a web site, for example) which allow the customer to purchase content or subscriptions outside of the app.

Enforcing this on an app such as Kindle promotes Apple’s own iBooks app and store.

There are lots of app stores out there, though one fewer with the forthcoming closure of AIR Marketplace, but how many of them matter? Here is my pick of the top three:

  • Apple iOS and Mac App Store – arguably two different stores, but since you access them with the same account I bracket them together.
  • Google Android Market – not a lock-in like Apple’s store, but still the primary store for Android.
  • Windows vNext marketplace – how this will work is not yet public, but the existence of a new app store in Windows 8 is widely rumoured and might be expected to tie in with what is already in place for Windows Phone 7.

Perhaps I am overstating the importance of the Windows 8 marketplace, given the failure of the Windows Vista marketplace, but given that Apple has now shown the way I find it hard to see how Microsoft can fail with this one.

Note that an app store is not just a marketing ploy. It is a software deployment and update tool.

App Stores score well in terms of usability. Another advantage is that users have a centralised mechanism for software updates, managed by the operating system. That is good for security, because it is unlikely to be disabled, and good for usability as it should mean fewer third-party updaters like those from Adobe, Oracle Java, Symantec and others.

App Stores typically enforce certain conditions on developers. In essence they must be well-behaved. For examples, the Mac App Store prohibits apps that request escalation to root privileges. Apple also rejects apps that use “deprecated or optionally installed technologies”, including specifically Java and by implication Adobe Flash or other runtimes.

This is great for security. In principle, if you decide that you will only install apps from the App Store, you can be confident that all your apps are well-behaved. On the Mac this is interesting; on Windows it would be a revolution.

What are the business implications though?

  • First, it is a significant source of new revenue for the operating system vendor. It gets a cut of everything.
  • Second, it gives tremendous empowerment to user ratings and reviews. On iOS or Android, if you want an app, you automatically search the app store and take note of factors such as user ratings and popularity. Most of us can figure that if there are few ratings or reviews, the app is not popular.

If you are a software company, getting high ratings and good reviews on app stores is now a key challenge, even more so than it is already with the likes of Amazon.

  • Speaking of Amazon, the third point is that app stores will not be welcomed by software resellers. They are simply being bypassed. Amazon is addressing this with its own App Store for Android; but can it really win against the official Google Android Market? Its MP3 store is better value than Apple’s iTunes, but has smaller market share.

Amazon has other business to fall back on, but specialist software resellers will be watching the growth of app stores nervously. Apple resellers in general are already hurting and diversifying, thanks in part to Apple bypassing them with releases like OS X Lion.

The app store revolution is good for users in many ways, especially as prices seem to end up lower than before, but there are worrying aspects. In particular, the ability of the operating system vendor to tilt the store in its own favour is a concern, and we will hear more complaints about that.

Finally, it is interesting to speculate how this may impact enterprise software deployment. Will Microsoft aim to link its forthcoming Windows app store to other deployment mechanisms such as System Center Configuration Manager? What about volume licensing sales, will resellers be able to keep hold of those? Maybe we will learn more of Microsoft’s story on this at the Build conference in September.

Microsoft financials: Office and server dominate as Windows falters

1 Comment

Microsoft has released its quarterly figures for January-March 2011. My at-a-glance summary is below.

Quarter ending June 30th 2011 vs quarter ending June 30th 2010, $millions

Segment Revenue Change Profit Change
Client (Windows + Live) 4740 -41 2943 -123
Server and Tools 4643 +494 1774 +214
Online 662 +94 -728 -40
Business (Office) 5777 +402 3618 +399
Entertainment and devices 1485 +341 32 +204

Business as usual? More or less, but there are a few points to note.

The figure that jumps out is the stunning performance of Office, which includes SharePoint and Exchange. Why is everyone buying Office 2010, when a document like the one I am typing now could be done just as well in Word 2.0 from 1991, or more plausibly the free OpenOffice?

The answer is the Microsoft has successfully transitioned many of its customers to using Office with SharePoint and Exchange, making it harder to stick with old versions and selling CALs (Client Access Licences) as well as the Office suite itself. This is highly profitable, though the aspect that puzzles me is that Office 365, which is cloud-hosted SharePoint and Exchange, is more cost-effective for the customer since it includes server software, CALs and in some cases the Office client for a commodity-priced subscription.

In other words, I find it hard to see how Microsoft can remain equally profitable if a significant proportion of its customers switch to Office 365. The company may be depending on its ability to upsell those customers to further online services; or perhaps it has not fully thought this through and has set Office 365 pricing at what it needs to be in order to compete with Google.

Fortunately for Microsoft, there is enough doubt concerning the safety of cloud services to sustain continued strong sales of on-premise solutions.

Second notable thing: Windows is in decline. The reason: it is losing market share to Apple and to Google Android. Netbook sales are down 41% according to the release, and I would guess that those sales have mostly gone to Apple iPad and Android tablets rather than to Windows notebooks.

Will Windows 8 reverse the decline? Speculation of course, but it will not repeat the success of Windows 7. In fact, my guess is that Windows 8 will be a hard sell to enterprises which have finally been persuaded to migrate from Windows XP. They are settling down for another five years of stability. Windows 7 was a consolidation release, just the sort of thing enterprises like. Windows 8 will be a revolution release, with most of the interest focused on what it can do in mobile and tablets. If it does succeed, it will do so slowly; there will be no rush to upgrade from 7 other than from the usual early adopters. It may improve sales in the consumer market, but neither Mac nor iPad nor Android is going away.

That leads on to mobile, the figures for which are buried under a pile of Xbox consoles. A good quarter for Xbox, though note how poor the margins are compared to those for Office or Windows.

Finally, the online money drain continues. Note that this is Bing and online advertising, not Azure or Office 365. Microsoft must feel that it the strategic value of these online services is worth the cost, particularly since they tie into mobile and the ecosystem which Nokia is depending on for a reversal of its fortunes. Given that the company has money to burn, there may actually be some sense in that; though for a segment to make such large and consistent losses over a long period has to be a concern.
