Lifetime registration as a Windows Store developer, now from £12

2 Comments

Microsoft has removed some friction from developing for the Windows Store (whether phone or Windows 8) by removing the requirement to pay an annual subscription:

As we continue to execute on the vision to integrate the Windows and Windows Phone developer experiences, we have taken another step by moving to a one-time lifelong Dev Center registration fee.

says Microsoft’s Todd Brix in a post today. He adds that the 600,000 developers already registered are covered, with no additional fee required.

How much is the fee? Brix does not say, and I could not find it quickly, so I started the signup process. I was offered individual registration for just £12.00. A company registration is £65.00.

Both fees are of course negligible for a developer, compared to the cost of developing an app that is worth installing. Considering that Microsoft has had problems with junk apps filling its store, you could argue that fees are justifiable as a means of restraining the flow of meaningless or malicious apps.

The counter-argument is that fees deter developers from getting started, and that today’s hobbyist may come up with the next Minecraft. It is better to control quality with a robust checking process before apps are admitted into the store.

I had a quick glance today, and have the impression that Microsoft has made progress in removing the worst offenders, following some agitation at the end of last month.

Microsoft is laying the foundation for another go at its app platform with the launch of Windows 9, about which we will hear more in a couple of weeks time.

Windows “9”: forget the Start menu, consider the apps

1 Comment

This week has seen multiple leaks of early builds of the next version of Windows – sometimes called Windows 9 or “Threshold” – showing Microsoft’s continuing inability to persuade all of its partners to keep secrets.

It seems to me that the leaks are likely to be genuine, though the usual health warnings apply. I also expect that Microsoft is deliberately holding back from releasing final UI designs, in part because they are likely to leak, so you should not read too much into the appearance.

The headline new features are a revamped Start menu which appears in the old position on the desktop, rather than on a separate screen; and the ability to run several desktops at once, as a way of organising your work.

No doubt the new Start menu will feel more comfortable for Windows 7 users, though for myself I am now used to the full-screen version and it is no big deal.

I am more interested in what is happening with Windows Store apps (also known as Metro or Windows Runtime apps). These are significant because it is this kind of app that you can easily port to Windows Phone using a Visual Studio Universal App project.

We saw these apps running in desktop windows, in a preview at the Build developer conference earlier this year. The leaked build seems also to have this feature. Check out the video here. Here is Calculator running on the desktop:

image

This is the Metro app, not the old desktop calculator. Here it is in Windows 8.1:

image

Note a big difference though: in Windows 8.1 you can get a window bar to appear along the top, but in Windows 9 there is also a maximize widget at top right of the window (in Windows, this doubles as a “restore down” button when the windows is already maximized).

Later in the video, we see this in operation. The user starts the Xbox Video app full screen:

image

and then hits the “restore down” button:

image

This is therefore the bridge between the “Metro” and desktop environments. Hit that button, and the full-screen experience becomes a windowed app on the desktop.

In another leaked image, the Charms menu options (a right-edge menu in Windows 8.x) becomes a drop-down window menu, summoned by clicking in the right-hand upper corner. Users often find the Charms menu awkward with mouse and keyboard (I still do) so this will be a more convenient alternative.

Now, although Windows experts can easily see the difference between a Metro app and a desktop app, I doubt that the average user will care. All they will note is that this kind of app requires Windows 8 or 9 to run.

Although this is a diminished target for developers, who may still prefer to write desktop apps that target Windows 7 (or XP) and higher, my guess is that this new UI will make Windows Runtime apps more visible and acceptable for users who live primarily in the desktop – which is most Windows users.

If Microsoft can increase the momentum behind this style of apps, then their benefits will be more apparent too: easy install and uninstall via the Store, low malware risk, and a UI that works well on tablets as well as with mouse and keyboard. This in turn would make more sense of the small Windows tablets from the likes of Toshiba, HP and Lenovo which we recently saw at IFA in Berlin.

There would be a knock-on benefit for Windows Phone, too, thanks to relatively easy porting between the two platforms.

What do you think – is desktop integration enough to rescue the Windows 8 app platform?

Book review: Professional ASP.NET MVC 5. Is this the way to learn ASP.NET MVC?

3 Comments

This book caught my eye because while I like ASP.NET MVC, Microsoft’s modern web application framework, it seems to be badly documented. Even the word “badly” is not quite right; there is lots of documentation, some of high quality, but finding your way around it is challenging, thanks to the many different pieces involved. When I completed an ASP.NET MVC project recently, I found it frustrating thanks to over-reliance on sample projects (hey, here is a an application we did that works, see if you can figure out how we did it), many out of date articles relating to old versions; and the opposite, posts and samples which include preview software that does not seem wise to use in production.

image

In my experience ASP.NET MVC is both cleaner and faster than ASP.NET Web Forms, the older .NET web framework, but there is more to learn before you can go ahead and write an application.

Professional ASP.NET MVC 5 gives you nearly 600 pages on the subject. It is aimed at a broad readership: the introduction states:

Professional ASP.NET MVC 5 is designed to teach ASP.NET MVC, from a beginner level through advanced topics.

Perhaps that is too broad, though the idea is that the first six chapters (about 150 pages) cover the basics, and that the later chapters are more advanced, so if you are not a beginner you can start at chapter 7.

The main author is Jon Galloway who is a Technical Evangelist at Microsoft. The other authors are Brad Wilson, formerly at Microsoft and now at CenturyLink Cloud; K Scott Allen at OdeToCode, David Matson who is on the ASP.NET MVC team at Microsoft, and Phil Haack formerly at Microsoft and now at GitHub. I get the impression that Haack wrote several chapters in an earlier edition of the book, but did not work directly on this one; Galloway brought his chapters up to date.

Be in no doubt: there are plenty of well-informed ASP.NET MVC people on this team.

The earlier part of the book uses a sample Music Store application, a version of which is publicly available here. You can also download a tutorial, based on the sample, written by Galloway. The public tutorial however dates from 2011 and is based on ASP.NET MVC 3 and Visual Studio 2010. The book uses Visual Studio 2013.

Chapters 1 to 6, the beginner section, do a decent job of talking you through how to build a first application. There are chapters on Controllers, Views, Models, Forms and HTML Helpers, and finally Data Annotations and Validation. It’s a good basic introduction but if you are like me you will come out with many questions, like what is an ActionResult (the type of most Controller methods)? You have to wait until chapter 16 for a full description.

Chapter 7 is on Membership, Authorization and Security. That is too much for one chapter. It is mostly on security, and inadequate on membership. One of my disappointments with this book is that Azure Active Directory hardly gets a mention; yet to my mind integration of web applications with Office 365 (which uses Azure AD) is a huge feature for Microsoft.

On security though, this is a useful chapter, with handy coverage of Cross-Site Request Forgery and other common vulnerabilities.

Next comes a chapter on AJAX with a little bit on JQuery, client-side validation, and Ajax ActionLinks. Here is the dilemma though. Does it make sense to cover JQuery in detail, when this very popular open source library is widely documented elsewhere? On the other hand, does it make sense not to cover JQuery in detail, when it is usually a vital part of your ASP.NET MVC application?

I would add that this title is poor on design aspects of a web application. That said, I was not expecting much on the design side; but what would help would be coverage of how to work with designers: what is safe to hand over to designers, and how does a typical designer/developer workflow play out with ASP.NET MVC?

I would also like to see more coverage of how to work with Bootstrap, the CSS framework which is integrated with ASP.NET MVC 5 in Visual Studio. I found it a challenge, for example, to discover the best way to change the default fonts and colours used, which is rather basic.

Chapter 9 is on routing, dry but essential background. Chapter 10 on NuGet, the Visual Studio package manager, and a good chapter given how important NuGet now is for most Visual Studio work.

Incidentally, many of the samples for the book can be installed via NuGet. It’s not completely obvious how to do this. I found the best way is to go to http://www.nuget.org and search for Wrox.ProMvc5 – here is the link to the search results. This lists all the packages available; note the package names. Then open the Nuget package manager console and type:

install-package [packagename]

to get the sample.

Chapter 11 is a too-brief chapter on the Web API. I would like to see more on this, maybe even walking through a complete application with clients for say, Windows Phone and a web application – though the following chapter does present a client example using AngularJS.

Chapter 13 is a somewhat theoretical look at dependency injection and inversion of control; handy as Microsoft developers talk a lot about this.

Next comes a very brief introduction to unit testing, intended I think only as a starting point.

For me, the the next two chapters are the most valuable. Chapter 15 concerns extending MVC: you learn about extending models with value providers and model binders; validating models; writing HTML helpers and Razor (the view engine in ASP.NET MVC) helpers; authentication filters and authorization filters. Chapter 16 on advanced topics looks in more detail at Razor, routing, templates, ActionResult and a few other things.

Finally, we get a look at how the Nuget.org application was put together, and an appendix covering some miscellaneous details like what is new in ASP.NET MVC 5.1.

Conclusions

I find this one hard to summarise. There is too much missing to give this an unreserved recommendation. I would like more on topics including ASP.NET Identity, Azure AD integration, Entity Framework, Bootstrap, and more. Trying to cover every developer from beginner to advanced is too much; removing some of the introductory material would have left more room for the more interesting sections. The book is also rather weighted towards theory rather than hands-on coding. At some points it felt more like an explanation from the ASP.NET MVC team on “why we did it this way”, than a developer tutorial.

That said, having those insights from the team is valuable in itself. As someone who has only recently engaged with ASP.NET MVC in a real application, I did find the book useful and will come back to some of those explanations in future.

Looking at what else is available, it seems to me that there is a shortage of books on this subject and that a “what you need to know” title aimed at professional developers would be widely welcomed. It would pay Microsoft to sponsor it, since my sense is that some developers stick with ASP.NET Web Forms not because it is better, but because it is more approachable.

Microsoft introduces a new 2D graphics API for the Windows Runtime

Microsoft has announced Win2D, a Windows Runtime API that wraps Direct2D (part of DirectX), for accelerated graphics in Windows Store apps.

The new API is described here and you can download the current binary here. It is in its early stages, but already supports basic drawing, bitmap loading, some image effects, and a vector and matrix math library. Here is some sample code:

void canvasControl_Draw(CanvasControl sender, CanvasDrawEventArgs args)
{
args.DrawingSession.Clear(Colors.CornflowerBlue);
args.DrawingSession.DrawEllipse(190, 125, 140, 40, Colors.Black, 6);
args.DrawingSession.DrawText("Hello, world!", 100, 100, Colors.Yellow);
}

Although this hardly looks exciting, it is important because it enables accelerated custom drawing from languages other than C++, and without needing to learn Direct2D itself. It will be easier to make rich custom controls, or casual 2D games.

That said, there are already alternative C# wrappers for DirectX in Windows Runtime apps, such as SharpDX.

Some of the comments on the MSDN post are sceptical:

Managed DirectX and XNA were however cancelled despite the frustration from the community which in response created open source alternatives to save the projects and customers that had invested in technology Microsoft introduced.

I understand that the future is "uncertain", but is this technology something that we should dare invest in or will it see the same fate as it’s earlier incarnations?

Microsoft’s Shawn Hargreaves assures:

Win2D is absolutely not a side project or some kind of stop gap that will later be replaced by anything different.

The target here is universal apps, so not just Windows Store apps but also Windows Phone. Despite the hesitant reception for the Windows Runtime in Windows 8, it looks as if Microsoft is still committed to the platform and that it will remain centre stage in Windows vNext.

Curating an app store: does Apple have it right?

3 Comments

No matter how much market share Android grabs: it is Apple’s App Store that started this app thing rolling. Never forget that OS vendors and phone operators tried to push app stores before Apple came in, but fragmentation, horrible user interaction design, billing issues and perplexing compatibility problems made them a dead loss for most users. Today, Apple’s mobile platform remains the most important one in many sectors.

The trade off with app stores is that you give up freedom of choice (install anything you want from anywhere) in return for a safer and better experience; software installation nasties like runtime dependencies, malware or fake download apps do not exist. At least, that is how it is meant to be, which is why some are so disappointed by Microsoft’s store.

Now Apple has offered us some limited insight into its own curation practice. It has published the top ten reasons for App rejections for the last week in August.

Aside from the generic “more information needed,” the top reason is bugs, and the next two are non-compliance with the developer terms (could mean anything) and user interfaces that are poor or too complex.

Close behind it is another key one:

Apps that contain false, fraudulent or misleading representations or use names or icons similar to other Apps will be rejected

which accounts for the main complaint about some apps that make it into Microsoft’s store.

What Apple does not tell us is the proportion of apps that are approved, either first time, or after one or two revisions.

There is little to argue about in Apple’s list of reasons to reject, except this one:

If your app doesn’t offer much functionality or content, or only applies to a small niche market, it may not be approved.

Apps without content are fair game, but why should small niche markets not be served? It does not bother me if a great app for jellyfish spotters makes it into the store.

The other factor here is that if an app store has enough high quality apps then the bad ones will be hardly visible, other than in search results. Store curation is about presentation as well as content.

Is Apple getting it right? I am not hearing much shouting from developers about the arbitrary or unknown reasons why their app was rejected, which suggests that it is, but it may be I am not listening intently enough.

Embarcadero RAD Studio XE7 (Delphi, C++Builder): is seven the magic number?

16 Comments

Embarcadero has released version 7 of its XE programming suite. The main products included are Delphi and C++ Builder, RAD development tools that share the same underlying libraries and visual designers but give developers a choice of language. Delphi uses an object-oriented evolution of Pascal.

image

Delphi is best known as a Windows Programming Tool – it used to be the main competition for Visual Basic – but over the last few years Embarcadero has added cross-platform Mac and mobile development with native compilers for OSX, iOS and Android. The IDE runs only on Windows but can compile for the Mac or for iOS New versions have come thick and fast – XE6 was released in April 2014 – so if you want to stay up to date, prefer for frequent upgrades or buy with a support and maintenance agreement. You can buy Delphi or C++ Builder separately if you do not require the suite.

The full RAD Studio also includes HTML 5 Builder, which supports mobile app development using Cordova (open source version of PhoneGap). There seems to be little new in HTML 5 Builder. An earlier PHP tool variously called Delphi for PHP and RadPHP was dropped some time back. I get the impression that Embarcadero is now more focused on its core good thing.

image

So what’s new? Making effective cross-platform development tools is not easy, with trade-offs between productivity (share more code) and writing the best app for each platform (share less code). This edition introduces a new approach to designing the user interface, called the Multi-Device Designer. It is based on a kind of inheritance. You build your base UI in a master form and write most of the event-handling code there. This master form is automatically adapted, to some extent, to other platforms. You can see how your form looks on these other platform by dropping down a list.

image

When you select the form for a specific platform, you can modify it for that platform. There is still only one form, but the platform-specific views override properties set in the master form. If you then further modify the master, the changes will flow down to the platform-specific forms unless properties have already been overridden.

image

My impression after a five-minute play is that you will indeed have to made modifications to get each form looking right; the automatically generated versions were not too good. There is still good productivity potential here presuming the designer proves to be robust.

A common criticism of Embarcadero’s approach is that visual controls are custom-drawn on each platform, rather than using true native controls. That does not matter at all, Embarcadero always assured me. It does matter though; and now in XE7 we have the beginning of a solution. There are a couple of optional Platform Native Controls, TEdit and TCalendar for iOS, which do use native controls. I suspect this will be popular and hope that more platform native controls arrive in due course.

App Tethering is a feature/library that lets you easily set up connectivity between Delphi/C++ Builder apps on a local network. The first version only supported Ethernet/Wi-Fi, but now Bluetooth support has come, including Bluetooth LE on Windows 8 and recent Android devices.

On Android, a new tool called Java2OP lets you generate Object Pascal interfaces for Java Android classes, which sounds handy.

Aside: the naming of this tool suggests that the language is now called Object Pascal again, rather than Delphi, which became the official name some years back. Object Pascal makes more sense to me.

The System.Threading library now includes a new parallel programming library, including Parallel For, task scheduling, and futures. Futures are a way of creating code that will run at an indeterminate time. You associate a variable with a function that calculates its value. That function will run when you access the value, or before that if a background thread is available.

The IDE now has limited Git support (local repository only).

Another new piece in XE7 is Enterprise Mobility Services, a REST-based middleware stack that runs as an ISAPI DLL in Microsoft’s IIS web server. This includes database connectivity (using the FireDAC library), user management (though not Active Directory integration as yet, as I understand it) and usage analytics.

If you are using IIS, why would you not use ASP.NET and the Web API? The answer is that with EMS you can do end-to-end Delphi/C++ Builder as well as getting the performance of native code on the server.

Challenges for Embarcadero and RAD Studio

In the nineties it was Delphi versus Visual Basic, and although most developers who gave Delphi serious attention discovered that it was superior in most ways to Microsoft’s tool, the big-company backing and integration with Microsoft’s overall platform meant that VB was not much disrupted (though we may have Delphi to thank for the appearance of native code compilation in VB).

Today Embarcadero is up against Xamarin, which is similar in that it gives Microsoft platform developers a route to cross-platform development for Mac, iOS and Android.

From what I hear, cross-platform support in RAD Studio has been successful in reinvigorating the product within its niche, but it is Xamarin that has grown explosively, thanks to a combination of the C# language, Visual Studio integration, and a degree of official endorsement from Microsoft. Whereas Xamarin fits with Microsoft’s Universal App concept, shared C# code across all platforms, RAD Studio takes its own path, avoiding .NET in favour of native executables.

[I realise that there is endless debate about what native means, and that while RAD Studio has a good claim to native code, it is weak when it comes to native controls as noted above].

Unlike Xamarin, which has its own cross-platform IDE for Windows and Mac, RAD Studio requires Mac developers to use a PC or a Windows VM.

Embarcadero chose not to support Windows 8 “Metro” or Store apps, a decision which now looks wise, though it could yet work against them if Universal Apps are more compelling in Windows vNext. Another omission is Windows Phone; perhaps this does not matter greatly given its small market share, but within the Microsoft platform community it is a bigger lack than simple market share implies.

The advantage of the RAD Studio approach is that it is less dependent on Microsoft’s constant changes of direction, and performance is generally good. I have always been a fan of Delphi. There were some quality concerns when the FireMonkey cross-platform UI library was first adopted, but now in RAD Studio XE7 there is reasonable hope that the library is mature enough.

RAD Studio is the obvious route for long-time Delphi or C++ Developers migrating to mobile; it is a viable niche but I question whether it can ever move beyond it to grab a share of the wider mobile development market.

Microsoft’s broken Windows Store: an unconvincing official response and the wider questions

5 Comments

Microsoft’s Todd Brix has posted about misleading apps in Windows Store:

Every app store finds its own balance between app quality and choice, which in turn opens the door to people trying to game the system with misleading titles or descriptions. Our approach has long been to create and enforce strong but transparent policies to govern our certification and store experience. Earlier this year we heard loud and clear that people were finding it more difficult to find the apps they were searching for; often having to sort through lists of apps with confusing or misleading titles. We took the feedback seriously and modified the Windows Store app certification requirements as a first step toward better ensuring that apps are named and described in a way that doesn’t misrepresent their purpose.

Although it is not mentioned, the post is likely in response to this article which describes the Windows Store as “a cesspool of scams”:

Microsoft’s Windows Store is a mess. It’s full of apps that exist only to scam people and take their money. Why doesn’t Microsoft care that their flagship app store is such a cesspool?

That is a good question and one which Brix does not answer. Nor are the complaints new. I posted in November 2012 about Rubbish apps in Windows Store – encouraged by Microsoft? with the extraordinary rumour that Microsoft employees were encouraging trivial and broken apps to be uploaded multiple times under different names.

The facts in that case are somewhat obscure; but there was no obscurity about the idiotic (if your goal is to improve the availability of compelling Windows Store apps) Keep the Cash campaign in March 2013:

Publish your app(s) in the Windows Store and/or Windows Phone Store and fill out the form at http://aka.ms/CashForApps to participate. You can submit up to 10 apps per Store and get $100 for each qualified app up to $2000.

image

Microsoft decided to reward mediocrity – no, even that is not strong enough – rather, to reward the distribution of meaningless trivial apps in order to pad out its store with junk and make the actual high quality apps (yes there are some) harder to find.

I agree with the commenters to Brix’s post who call him out on his claim that “Our approach has long been to create and enforce strong but transparent policies to govern our certification and store experience”. How do you reconcile this claim with the torrent of rubbish that was allowed, and even encouraged, to appear in the store?

Every public app store is full of junk, of course, and it is hard to see how that can be completely avoided; if Apple, Google or Microsoft declined apps for subjective reasons there would be accusations of exerting too much control over these closed platforms.

That does not excuse the appearance of apps like Download Apple Itunes (sic) for PC, listed today under New & rising apps:

image

The app is nothing to do with Apple; it is a third-party downloader of the kind I analysed here. The idea is to persuade people to run an application that installs all sorts of adware or even malware before directing them to a download that is freely available.

It seems that users do not think much of this example, which apparently does not even do what it claims.

image

While apps like this are making in into the store, I do not see how Brix can justify his claim of enforcing “strong but transparent policies to govern our certification and store experience”.

Even VLC, where scammy apps have been largely cleaned up following many complaints, is still being targeted. Apparently Microsoft’s store curators are happy to let through an app called “Download VLC Letest” (sic).

image

How much does this matter or has this mattered? Well, Microsoft launched Windows 8 at huge risk, trading the cost of unpopular and disruptive changes to the OS and user interface for the benefit of a new more secure and touch-friendly future. That benefit depended and depends completely on the availability of compelling apps which use the new model. The store, as the vehicle of distribution for those apps, is of critical importance.

Another benefit, that of protecting users from the kind of junk that has afflicted and diminished the Windows experience for many years, has been scandalously thrown away by Microsoft itself. It is a self-inflicted wound.

What could Microsoft do? It is too late for Windows 8 of course, but the correct approach to this problem, aside from not approving harmful and deceitful apps in the first place, is to take a strongly editorial approach. For less cost than was spend actually undermining the store by paying for rubbish, Microsoft could have appointed an editorial team to seek out strong apps and include within the store features that describe their benefits and tell their story, making the green store icon one that users would actually enjoy tapping or clicking. Currently there is too much reliance on automated rankings that are frequently gamed.

There are some excellent apps in the store, and teams that have worked hard to make them what they are. Apps to mention, for example, include Adobe’s Photoshop Express; Microsoft’s Fresh Paint; or Calculator Free. Those developers deserve better.

Xamarin announces large round of funding, plans international expansion

It is a case of “right time, right place” for Xamarin, as it scoops up Windows developers who need either to transition to iOS and Android, or to add mobile support to existing applications. You can also port applications to the Mac with its cross-platform development framework based on C#; no bad thing as Mac sales continue to boom.

image

Xamarin also fits with Microsoft’s new strategy, as I understand it, which is to provide strong support for iOS and Android for applications such as Microsoft Office, and services such as those hosted on Microsoft Azure.

Now the company has announced an additional $54 million of funding, which CEO Nat Friedman tells me is “the largest round of financing achieved by any mobile platform company ever”.

The financing comes from “new and existing investors, including Lead Edge Capital, Insight Venture Partners, Charles River Ventures, Ignition Partners, and Floodgate.”

What will the money be spent on? “Two things,” says Friedman. “We’re planning to expand our sales and marketing into Europe. We’re opening a sales office in London in the Fall. We did a roadshow with Microsoft in Europe and it was extremely successful. Second, we’re going to invest in improving the quality of our platforms.”

Friedman notes that mobile should not be considered a development niche. “Our view is that in the future all software will be mobile software in some way or another, when you build an application it will have to have some kind of mobile surface area.”

A few other points to note. One is that Xamarin Forms, recently introduced, has been a big hit with developers. “The Xamarin Forms forum has been our most popular forum,” says Friedman. “We’ve been really surprised.”

The company used to promote the idea of avoiding cross-platform code for the user interface, but then introduced Xamarin Forms as a cross-platform GUI framework, arguing that because it uses only native controls, it avoids the main drawbacks of the idea.

Some of the funding then will go into improving Xamarin Forms and tools to work with the framework.

Another key area is Visual Studio integration. The acquisition of the Visual Studio integration team from Clarius Consulting, in May 2014, is also significant here, since Clarius had strong expertise in this area.

Might Microsoft try to acquire Xamarin? Interesting question, and one which Friedman is not in a position to discuss; I am not a financial expert but would guess that Xamarin’s independent expansion increases its ability to be independent, though investors may be hoping to reap the rewards of an acquisition, who knows?

Bing Developer Assistant adds code samples to Visual Studio IntelliSense, with mixed results

Microsoft has updated its Bing Developer Assistant Beta, a Visual Studio 2013 add-in which hooks into IntelliSense so that you get code samples as well as brief documentation. For example, in an Entity Framework project, if you select dbContext.SaveChanges, you get a code sample which uses that method.

image

There is no guarantee of course that the sample is relevant to what you are trying to accomplish. You can hit Search More though and get a selection of code snippets and sample projects, drawn from sites including MSDN, StackOverflow and Codeproject.

image

Developer beware though. Looking at the code samples, the top one is from a 2011 blog post relating to CTP (Community Tech Preview) 5 of Entity Framework 4.1. If you hit the link, you get this:

image

“The information in this post is out of date”, it says, followed by a link to what is in fairness a rather helpful article on using SaveChanges.

Hmm, maybe Bing Developer Assistant should try filtering the search to eliminate samples on preview or obsolete APIs? A snag here though is that on occasion the blogs and samples on preview frameworks are all you can get, because by the time the thing is actually released, the developer evangelists have move on to blog about the next up and coming cool thing.

If you choose an object member for which Bing finds no code sample, you are prompted to add one of your own:

image

This takes to to the Developer Network sample upload page:

image

This form is quite a lot of work, but lets you add a code snippet or sample project together with title and comments explaining what it does.

The Bing Developer Assistant also searches for sample projects:

image

Again it is a case of picking and choosing what is really relevant; but developers are experts and expected to use common sense.

A drawback with Bing Developer Assistant is that only one add-on can extend IntelliSense, so if you use Resharper or another tool which also does this, you have to choose which one to allow.

In the end, this is all about integrating web search into the IDE. Is that a good idea, or is it better simply to have your web browser open, perhaps on another display, and type “dbContext SaveChanges EF6” or some such into your favourite search engine?

There is some merit in a search engine that automatically filters to show only code samples – hey, that is what Google’s popular Code Search did, until it was mysteriously shut down – though I’m not sure how much I like the idea of possibly obsolete and deprecated samples showing up in Visual Studio as you are coding.

Still, the truth is that web search is critical to software development today and it is good to see that recognised.

The UK government is adopting Open Document: some observations

9 Comments

The UK government is adopting the Open Document Format for Office Applications, for documents that are editable (read-only documents will be PDF or HTML). You can read Mike Bracken’s (Government Digital Service) blog on the subject here, and the details of the new requirements here. If you want to see the actual standards, they are on the OASIS site here.

I followed the XML document standards wars in some details back in 2006-2008. The origins of ODF go back to Sun Microsystems (a staunch opponent of Microsoft) which acquired an Office suite called Star Office, made it open source, and supported OpenOffice.org. My impression was that Sun’s intentions were in part to disrupt the market for Microsoft Office, and in part to promote a useful open standard out of conviction. OpenOffice eventually found its way to the Apache Foundation after Oracle’s acquisition of Sun. You can find it here.

During the time, Microsoft responded by shifting Office to use XML formats by default – these are the formats we know as .docx, .xlsx etc. It also made the formats an open standard via ECMA and ISO, to the indignation of ODF advocates who found every possible fault in the standards and the process. There were and are faults; but it has always seemed to me that an open XML standard for Microsoft Office documents was a real step forward from the wholly proprietary (but reverse engineered) binary formats.

The standards wars are to some extent a proxy for the effort to shift Microsoft from its dominance of business document authoring. Microsoft charges a lot for Office, particularly for businesses, and arguably this is an unnecessary burden. On the other hand, it is a good product which I personally prefer to the alternatives on Windows (on the Mac I am not so sure), and considering the amount of use Office gets during the working day even a small improvement in productivity is worth paying for.

As a further precaution, Microsoft added ODF support into its own Office suite. This was poor at first, though it has no doubt improved since 2007. However I would not advise anyone to set Microsoft Office to use ODF by default, unless mandated by some requirement such as government regulation. It is not the native format and I would expect a greater likelihood that something could go slightly wrong in formatting or metadata.

Bracken does not mention Microsoft Office in his blog; but as ever, the interesting part of this decision is how it will impact Office users in government, or working with government. If it is a matter of switching defaults in Office, that is no big deal, but if it means replacing Microsoft Office with Open Office or its fork, Libre Office, that will have more impact.

The problem with abandoning Microsoft Office is not only that that the alternatives may fall short, but also that the ecosystem around Microsoft Office and is document formats is richer – in other words, tools that consume or generate Office documents, add-ins for Office, and so on.

This also means that Microsoft Office documents are, in my experience, more interoperable (not less) than ODF documents.

That does not in itself make the UK government’s decision a bad one, because in making the decision it is helping to promote an alternative ecosystem. On the other hand, it does mean that the decision could be costly in constraining the choice of tools while the ODF ecosystem catches up (if it does).

How does the move towards cloud services like Office 365 and Google Docs impact on all this? Microsoft says it supports ODF in SharePoint; but for sure it is better to use Microsoft’s own formats there. For example, check the specifications for Office Online. You can edit docx in the browser, but not odt (Open Document Text); it is the same story with spreadsheets and presentations.

Google has recently added native support for the Microsoft formats to Google Docs.

Amazon’s Zocalo service, which I have just reviewed for the Register, can preview Microsoft’s formats in the browser, but while it also supports odt for preview, it does not support ods (Open Document Spreadsheet).

A good decision then by the UK government? Your answer may be partly ideological, but as a UK taxpayer, my feelings are mixed.
