Microsoft warns against installing 64-bit Office 2010 unless you really need it

12 Comments

Microsoft has released 64-bit Office 2010, at least to MSDN and Technet subscribers, with general availability to follow shortly. Now that 64-bit Windows is commonplace, you would think that 64-bit Office is the obvious choice.

Apparently not. Take a read of this technical note before installing 64-bit Office 2010. In essence, it recommends installing 32-bit Office, even on 64-bit systems, except in the following case:

If some users in your organization are Excel expert users who work with Excel spreadsheets that are larger than 2 gigabytes (GB), they can install the 64-bit edition of Office 2010. In addition, if you have in-house solution developers, we recommend that those developers have access to the 64-bit edition of Office 2010 so that they can test and update your in-house solutions on the 64-bit edition of Office 2010.

That’s a small niche. So what can go wrong if you decide to go 64-bit? First, it might not install:

If 32-bit Office applications are installed on a computer, a 64-bit Office 2010 installation is blocked by default.

says the tech note. In addition, if you manage to install it, you will have problems with 32-bit Access applications, 32-bit ActiveX controls and COM add-ins, in-place activation of documents where the OLE server is 32-bit, and VBA code that calls the Windows API. VBA deliberately disables API calls defined with the Declare statement; they must the updated with a PtrSafe attribute before they will run.

The Office install DVD includes both 32-bit and 64-bit versions, and the 32-bit version installs by default irrespective of the version of Windows.

Of course I will be trying 64-bit Office on a spare machine. I’m interested to know, for example, whether Outlook benefits from all that extra RAM, since it is notoriously slow. But overall, 64-bit Office 2010 looks more like a release to prepare the ground for the future, than one for normal use.

Microsoft Expression Blend is too hard to learn

9 Comments

Expression Blend is the design tool for Windows Presentation Foundation (WPF) and Silverlight, and thus a key tool for building applications for the current generation of Microsoft’s platform. How good is it? There is a shortage of in-depth reviews, if my quick Google search is anything to go by, though there are plenty of quick write-ups saying that it is not as good as Adobe Flash. Blend got a bit of attention following the 2009 Mix conference thanks to SketchFlow, the prototyping feature built into Blend 3, and which has been well received.

One reason for Blend’s relatively low profile is that it is aimed at designers, whereas Microsoft’s community is more developer-focused. WPF developers can avoid Blend to a large extent, by using the designer built into Visual Studio, which is fine for laying out typical business applications. Now with Visual Studio 2010 the same is true for Silverlight. Another option is to write your own XAML code, which works for laying out controls though it is inconceivable for drawings. XAML is verbose

It is just as well you can avoid it, because although Blend is very capable, it is not easy to learn. I’m guessing there are quite a few developers who have opened it up, clicked around a bit, and retreated gratefully back to Visual Studio. This was a problem for Adobe Flash Professional as well, and one of the reasons for the creation of Flex and Flex Builder, a code-centric IDE for the Flash runtime.

You can argue that a design tool does not need to be easy for developers to use; it needs to be good enough for designers to create great designs. That’s true; but the developer/design divide is not a absolute one, and ideally Blend should be something a developer can dip into easily, to create or enhance a simple layout, without too much stress.

Maybe some developers can; but I have not found Blend particularly intuitive. The user interface is busy, and finding what you want or getting focus on the right object can be a challenge.

As evidence of this, take a look at Adam Kinney’s Through the Eyes of Expression Blend tutorial, which is among the best I have found. Try lesson 9, Styling and working with design-time data. Then ask yourself how easy it would be to discover the way to do this without the step-by-step instructions. Would you have known to right-click the StackPanel and choose Change Layout Type > Grid? What about step 8, right-clicking the ListBox, and selecting Edit Additional Templates > Edit Layout of Items (Items Panel) > Create Empty?

image  

And notice how in step 9 you have to click the “small grey square next to the Source property”, that’s the one called Advanced Options:

image

Overall it is a nice tutorial, but you might need an evening or two with a couple of fat books, one on XAML and one on Blend itself (if you can find a good one), in order to understand the features you have have been using.

It is probably worth it, if you intend to work with Silverlight or WPF. Blend has one great advantage over Flash Professional: it authors XAML, and you can open it up in Visual Studio and continue working on it there. Microsoft has no need for something like Adobe Catalyst to bridge the XML/Designer divide.

Still, Microsoft had a clean slate with Blend, which is only a few years old, and it is a shame it could not come up with something a bit more user-friendly.

The other implication is that the new visual designer in Visual Studio 2010 makes Silverlight applications a great deal easier to create. You can Blend if you want to; but the Visual Studio effort is far more approachable.

How do you find Blend? I’d be interested in other perspectives.

Silverlight 4 vs Silverlight 3: a little bit faster?

7 Comments

Microsoft’s Scott Guthrie spoke of “twice as fast performance” in the newly-released Silverlight 4, thanks to a new just-in-time compiler.

Performance is a hard thing to nail down. Maybe he meant that compilation is twice as fast? I’m not sure; but I tried a couple of quick tests.

First, I looked at my Primes test. Version 3 running in Windows Vista took around 0.40 seconds (the exact figure varies on each run, thanks to background processes or other factors). I then upgraded to version 4.0. No significant difference, on average over several runs. I used Vista because I’d already upgraded my Windows 7 install.

Next I tried Bubblemark. I maxed it out at 128 bubbles. On Vista with Silverlight 3 I got about 240 fps; on the same machine with Silverlight 4 about 260fps; about 8%.

Next I tried on an Apple Mac. My Mac Mini is less powerful, though not that bad, an Intel 1.83 Ghz Core Duo. On the Prime test I got 0.54 secs before, and 0.50 secs after the upgrade to 4.0, about 7.5% improvement. On Bubblemark, it was only 24 fps before and after.

I guess the vast difference in graphics performance is also interesting. It is not just Mac vs Windows; the Nvidia GeForce 6800 on the PC is more powerful than whatever is in the Mac Mini.

If anyone can tell me in what respect version 4.0 is twice as fast, I’d be grateful.

Update: prompted by the comment from David Heffernan below, I also tried the Encog Silverlight Benchmark. I used an older core duo laptop, since I am running out of machines to upgrade. I ran the test twice before upgrading, and twice after. Lower is better:

Silverlight 3.0: 22.0

Silverlight 4.0: 12.7

That’s about 42% better, where “twice as fast” would be 50% better, much closer to Guthrie’s claim. I guess it depends what you measure.

Silverlight 4.0 released to the web; tools still not final

2 Comments

Microsoft released the Silverlight 4.0 runtime yesterday. Developers can also download the Silverlight 4 Tools; but they are not yet done:

Note that this is a second Release Candidate (RC2) for the tools; the final release will be announced in the coming weeks.

Although it is not stated explicitly, I assume it is fine to use these tools for production work.

Another product needed for Silverlight development but still not final is Expression Blend 4.0. This is the designer-focused IDE for Silverlight and Windows Presentation Foundation. Microsoft has made the release candidate available, but it looks as if the final version will be even later than that for Silverlight 4 Tools.

Disappointing in the context of the launch of Visual Studio 2010; but bear in mind that Silverlight has been developed remarkably fast overall. There are huge new features in version 4, which was first announced at the PDC last November; and that followed only a few months after the release of version 3 last summer.

Why all this energy behind Silverlight? It’s partly Adobe Flash catch-up, I guess, with Silverlight 4 competing more closely with Adobe AIR; and partly a realisation that Silverlight can be the unifying technology that brings together web and client, mobile and desktop for Microsoft. It’s a patchy story of course – not only is the appearance of Silverlight on Apple iPhone or iPad vanishingly unlikely, but more worrying for Microsoft, I hear few people even asking for it.

Even so, Silverlight 4.0 plus Visual Studio 2010 is a capable platform; it will be interesting to see how well it is taken up by developers. If version 4.0 is still not enough to drive mainstream adoption, then I doubt whether any version will do it.

That also raises the question: how can we measure Silverlight take-up? The riastats charts tell us about browser deployment, but while that is important, it only tells us how many have hit some Silverlight content and allowed the plug-in to install. I look at things like activity in the Silverlight forums:

Our forums have 217,426 threads and 247,562 posts, contributed by 77,034 members from around the world. In the past day, we had 108 new threads, 529 new posts, and 70 new users.

it says currently – substantial, but not yet indicative of a major platform shift. Or job stats – 309 UK vacancies right now, according to itjobswatch, putting it behind WPF at 662 vacancies and Adobe Flash at 740. C# on the other hand has 5349; Java 6023.

Dancing on a pin: Microsoft belatedly answers Open XML critics

Microsoft’s Doug Mahugh has replied to accusations from ISO expert Alex Brown that the company is doing little to implement its own Open XML standard. The issue is that the XML document formats in Office 2007 are, from the ISO perspective, meant to be “Transitional” – a compromised format designed to interoperate with existing binary documents – and that the standard Microsoft is meant to be implementing is “Strict”, an improved standard that can more easily be implemented by others.

Mahugh says:

I’d like to state clearly and unequivocally at this time that we will support reading and writing of ISO/IEC 29500 Strict no later than the next major release of Office, code-named Office “15.”

He doesn’t say whether or not it “Strict” will be the default in Office 15, which we can expect to see in around 2013. This is the real pain-point for users: if the default changes, the result is the frustration of sending or receiving unreadable documents.

Microsoft is dancing on a pin. On the one hand, it wants to convince governments, academics and other standards-sensitive organisations that Microsoft Office does the right thing. On the other hand, the benefit to users of breaking document compatibility for the sake of ISO compliance is rather invisible.

Document compatibility is the thinking behind having read-only support for Strict in Office 2010 (and coming to Office 2007). If Microsoft can get read-only support widely deployed, then in 2013 the Strict documents that start to circulate will not be so problematic.

The approach is not completely unreasonable; these things take time. That said, Microsoft’s communication of its intentions has been poor. Further, Mahugh does not answer the parts of Alex Brown’s post that address quality:

It is also a worrying commentary on the standards-savvyness of the Office developers that the first amateur attempts of part-time outsiders find problems with documents which Redmond’s internal QA processes have missed. I confidently predict that fuller validation of Office document is likely to reveal many problems both with those documents, and with the Standard itself, over the coming years.

My perspective on this as a journalist is that Microsoft did not consider Open XML or standards compliance even worth a mention in its publicity so far and its detailed reviewers’ guide for Office 2010. That suggests it is not much of a priority.

So full support in 2013 or thereabouts. My expectation is that by then saving and editing documents online will be more common than it is today, and that the assumptions the Office team seems to make about the steady progress of its huge desktop suite are likely to prove faulty.

Book Reviews: Programming F# and Beginning F#

2 Comments

I’ve been working with Microsoft’s new language F# recently and enjoying it. If it catches your interest, you might turn to a book in order to familiarise yourself with the basics. Here are two which I’ve looked at. They are both aimed at experienced developers who are new to F#.

Programming F# by Chris Smith

Programming F# comes from O’Reilly. It kicks off with Hello World and an introduction to the interactive console in Visual Studio 2010 – a great way to try out F#. Next we get a summary of types, and a brief explanation of how to write an F# program – stuff you have to know.

Chapter 3 is an introduction to functional programming, and also mentions type inference, an important F# feature. The following chapter explains mutable programming in F# – yes, you can do it; it is just not the default behaviour – and also covers exceptions. Chapter 5 turns to object-oriented programming in F#, another distinctive feature, while chapter 6 covers aspects specific to .NET such as garbage collection. That’s about half the book, and gets you up and running with the language.

The second half of the book is more interesting, looking at ways of using F#. Smith looks at applied functional programming, including pattern matching, recursion, continuations and closures. Next, there’s a look at applied object orientation. Chapter 9 covers scripting with F# – an interesting use case – and includes welcome examples for things like copying files and automating Microsoft Office. Chapter 10 is a key one, explaining computation expressions that let you create workflows and all-but extend the language. It’s “a very advanced concept that even expert developers can have a hard time grasping,” admits the author, though he presents it clearly.

Next we get a section on a likely reason for picking up F#: asynchronous and parallel programming. There’s a wide-ranging chapter explaining both .NET and F# asynchronous techniques, including the .NET Parallel Extensions. It’s a little confusing, especially since Smith observes that F# asynchronous workflows are sub-optimal for CPU parallelism; he recommends the .NET Parallel Extensions because of the better thread management it offers.

The last chapters cover .NET Reflection, code analysis and generation with Quotations – “deep wizardry”, says the author. An appendix summarises .NET Libraries and F# interop with COM and native code.

While this is an excellent language introduction, and thorough within the topics it covers, some aspects disappointed me. I cannot find any mention of F# agents, based on the MailboxProcessor class (nothing to do with email), which is a surprising omission; F# designer Don Syme sees it as a critical feature for scalable web development. Nor is there anything on graphics processing, another common usage, or any hint about how you might use F# for financial analysis. I also found it rather dry overall – hard to avoid with so much plumbing to cover, but I feel the author could have conveyed a little more excitement about what F# enables. Don’t make this the only F# book you read.

Beginning F# by Robert Pickering

This Apress title covers similar ground as the O’Reilly book, but with a slightly more hands-on and informal style, which on the whole I enjoyed. It starts with an introduction including a quote from Ralf Herbrich at Microsoft Research describing how he converted 1000 lines of C# into 100 lines of F# which performed just as well – this is the kind of real-world touch that makes you want to read on. The second chapter explains how to install F#, including different versions of Visual Studio, the open source SharpDevelop, and Mono on Linux – excellent diversity. Chapter 3 introduces functional programming, in effect a brisk overview of the core of F#. Read it slowly!

The author goes on to look at imperative programming and mutability in F#, and then object orientation, just as Smith did in his book. Chapter 6 is useful overview of how code is organised into modules and namespaces, and also covers comment annotations. Next, Pickering looks at F# libraries, including a brief look at math programming. Chapter 8 covers user interface coding – completely lacking in Smith’s book – complete with a quick look at GTK#, which works on Linux. There’s also a quick look at ASP.NET, Microsoft’s web server platform. Although this little introductions are too brief to be really useful, they do spark ideas about how you might use F#.

Data Access is next, another important real-world topic, covering XML, LINQ (Language Integrated Query) and ADO.NET.

Chapter 10 is when we get to parallel programming and reactive programming – code that waits for an external event before running. Pickering introduces F# agents and the MailboxProcessor class. Next comes a look at distributed applications using sockets, HTTP requests, web services, and Windows Communication Foundation.

Chapter 12 has the intriguing title Language-Oriented Programming, and should be taken together with the next chapter on parsing text. This is where we look at using data structures as little languages, parsing and interpreting text, and extending F# syntax. Finally, chapter 14 is the interop chapter, covering interop with C# as well as platform invocation for COM and native code.

Of the two books, this is the more lively and wide-ranging read, and more likely to enthuse you about the possibilities F# offers, though it skims the surface in places; many topics receive only shallow coverage.

Jewels from the loft: launch of Delphi, Netscape’s Constellation, HTML to die, Longhorn for developers

5 Comments

It’s the Easter holiday in the UK and I’ve suffered a bout of spring-clean fever. It is time, I decided, to clear out a mountain of old books and magazines.

A job like this always prompts reflections, the first of which is the sad decline of print journalism in the field of software development. It hurt to send piles of Byte, Exe, Dr Dobbs’s Journal, Application Development Advisor and others off for recycling.

image

A few things caught my eye. Exe June 1995, and there is a young Anders Hejlsberg talking to Will Watts about his new creation: Borland Delphi:

Before Delphi, you always had to make a choice. Do I go for the performance of a native code compiler, or the ease of use of a visual development environment? Do I go for a powerful object-oriented language, or a proprietary 4GL client/server tool? What programmers really want is all of the above, in one package. That’s what we set out to do.

What is striking about Delphi is that this was not hype. It delivered on that promise. It was better than its obvious rival, Microsoft’s Visual Basic, in almost every way (I will give VB a point for sheer ubiquity, especially in VBA guise). Delphi is still with us today, not bad after fifteen years. However, it never came close to VB’s market share, which shows that quality has never been the sole or even the most important determinant of sales success.

Next up is Byte, March 1998. “Reinventing the Web”, the cover proclaims. “XML and DHTML will bring order to the chaos”.

image

Inside there is a breathless description of how XML will change everything, and a quote from Jon Bosak:

HTML, this so-called ‘hypertext markup language,’ implements just a tiny amount of the functionality that has historically been associated with the concept of hypertext systems. Only the simplest form of linking is supported – unidirectional links to hard-coded locations. This is a far cry from the systems that were built and proven during the 1970s and 1980s.

Indeed. “We need to start replacing simple HTML with more powerful alternatives”, the article concludes. “The migration to XML must begin. The future of the Web depends on it.”

Here’s one thing that mostly did not work out as planned. The W3C tried to retire HTML, failed, and is now belatedly engaged in specifying HTML 5.

Byte March 1997 is also intriguing. Netscape’s Marc Andreessen smiles out of the cover.

image

Jon Udell, in the days before he disappeared into some Microsoft corridor, writes about Netscape’s “Constellation: the network-centric desktop”:

Netscape’s Constellation takes a less Windows-centric approach and puts more emphasis on location-independent computing, regardless of the platform. No matter what kind of system you’re using or where you are, Constellation presents a universal desktop called the Homeport. Although the Homeport can appear in a browser window, Netscape usually demonstrates it as a full-screen layer that buries the native OS – certainly one reason Microsoft is not embracing Constellation.

Netscape got a lot of things right, a true pioneer of what we now call cloud computing. What went wrong? Well, Microsoft went all-out to conquer Netscape by removing its browser dominance. Microsoft’s weapon was the free Internet Explorer.

It is all a pre-echo of what is happening now with Google and Microsoft, the difference being that Google has huge financial power thanks to its marriage of internet search and internet advertising. Unlike Netscape, Google is winning.

This blog is long enough; but I’ll give a brief mention to another jewel from the archives: a book given out at PDC 2003 entitled Introducing Longhorn for Developers.

image

It describes Microsoft’s vision for Longhorn: a radical new application model for Windows, building on XAML, WinFS and “Indigo”, the communication framework. It bears little resemblance to what eventually appeared as Vista, which is a shame as it was compelling in many ways.

Microsoft accused of failure to observe Open XML standards process

2 Comments

XML specialist Alex Brown, who was involved in the ISO standardisation of Microsoft’s Open XML – still perhaps best known as OOXML – says Microsoft has failed to honour the commitments it made when the standard was approved. In particular, it seems little progress has been made between Office 2007 and Office 2010. The key problem is that Microsoft implemented Open XML before it was standardised. There were numerous changes made during the standardisation process, but what to do about the existing implementation? Loosely, the existing unacceptable format was given a “Transitional” status, while the more satisfactory, corrected format was called “Strict”. Microsoft promised to implement the “Strict” variant as soon as it could. Brown adds:

I was convinced at the time, and remain convinced today, that the division of OOXML into Strict and Transitional variants was the innovation which allowed the Standard to pass. Enough National Bodies could then vote in good conscience for OOXML knowing that their preferred, Strict, variant would be under their control into the future while the Transitional variant (which – remember – they had effectively rejected in 2007) would remain purely for the purpose of accurately specifying old documents: a useful aim in itself.

It is now two years since Open XML was approved, and Microsoft is on the brink of releasing a new version of Office. So does Office 2010 implement Open XML Strict? Apparently not – it’s the Transitional version. That is bad enough; worse still, according to Brown, it does not even conform correctly to that:

It is also a worrying commentary on the standards-savvyness of the Office developers that the first amateur attempts of part-time outsiders find problems with documents which Redmond’s internal QA processes have missed. I confidently predict that fuller validation of Office document is likely to reveal many problems both with those documents, and with the Standard itself, over the coming years.

Note that Brown is basing his remarks on the preview of Office 2010; we have not seen the final release yet. I can believe that Microsoft may fix some issues, but it looks vanishingly unlikely that Office 2010 will implement the “Strict” standard which ISO approved.

Brown’s remarks shed light on something I noticed when reviewing the preview:

As for Open XML, it’s notable that Microsoft neglects to mention it at all in its Reviewer’s Guide, even though this is supposedly the release that will fully implement ISO/IEC 29500. It is odd how this has gone from a cause to campaign for, to not-worth-mentioning in just over a year. To be fair, few users ever cared about XML formats themselves: it is only when documents get scrambled or fail to open that such things become important.

No wonder Microsoft said nothing about it, if in reality it has lost interest in conformance.

I think it is a good thing for Microsoft to standardise its Office formats. Selfish manipulation of standards committees on the other hand is not acceptable. One thing is for sure: if Brown is right and

without a change of direction, the entire OOXML project is now surely heading for failure.

then the company will only have itself to blame. Its nightmare will re-emerge: entire governments mandating OpenOffice for the sake of  standards conformance.

That said, and despite the hype, I regard Office 2010 as a minor release. 64-bit Excel, a few tweaks, and a first foray into browser-hosted versions. Microsoft often displays this pattern, following up a release with major changes – Office 2007, for example – with one that is really just a refinement of what went before. It is not impossible that somewhere in the corridors of Redmond a team is working on a new Office that does a much better job with the Open XML standard.

Over to Microsoft – serious about Open XML? Or just doing the minimum necessary to protect a lucrative market dominance – maybe a bit less than the minimum?

Update: Microsoft’s Doug Mahugh has replied to Brown’s comments here. I am writing separately about this.

Android the new Windows?

I’ve just reviewed the LG GW620 Android phone. I was impressed by its features but disappointed by its usability – it’s not that bad, but scrolling web pages accurately with touch I found almost impossible – it’s hard to avoid scrolling too far and missing out a chunk – and why does LG supply the device with four different email clients?

Apple’s iPhone is much more expensive and compares badly on features, but has the usability and polish that the LG phone lacks.

OEM Android versus Apple iPhone – it reminds me of Windows vs Apple on the desktop.

One is for the mass market, cheap, feature-rich, a bit chaotic, always a few annoyances, but you put up with them because you can still get things done, and it’s an open platform which lets you do what you like.

The other is premium-cost, single-vendor, less annoying, and you spend more time getting on with what you want to do and less time fighting the machine.

I don’t intend this as a  complete parallel. There are more than two popular operating systems in the SmartPhone market right now – Symbian, Meego, WebOS, Blackberry; and Microsoft has big hopes for Windows Phone 7. That said, it is hard to see all these platforms thriving long-term.

Sony locks down the PS3 – removes Other OS support from all models

2 Comments

Sony is removing the ability to install an alternative operating system such as Linux on the Playstation 3. In a blog post, Sony’s Charlotte Panther says:

PS3 Firmware 3.21 will be available this Thursday. It will disable the “Install Other OS” feature that was available on the PS3 systems prior to the current slimmer models, launched in September 2009. This feature enabled users to install an operating system, but due to security concerns, we’re now removing this feature.

Panther suggests not upgrading the firmware as a workaround, but observes that this will block access to the PlayStation Network.

It is a move that will matter little to most PS3 owners, but a great deal to the few who were doing interesting work with the cell processor that runs Sony’s games console.

The wider picture is that we are seeing a rise in locked-down devices across the industry. Games consoles are generally like this – the Xbox 360 is the same – as are most mobile phones. Apple is now extending the iPhone model, where users have limited access to the device, to the larger iPad. As I understand it, Google intends that ChromeOS devices will also be locked down, though it is too early to say whether installing alternative operating systems on these will be possible. Sony mentions security, and certainly having a protected operating system that can only be updated by the vendor is an excellent security feature.

The downside is that it gives greater power to the vendor, to control what you can do with the device, stifle creativity, and potentially to charge more for applications and extensions than is possible with an open system.

There is a good explanation of how this works in Daniel Lyons’ recent piece on the Apple iPad.
