The strategy behind Mono has shifted: ten years of open source .NET

Yesterday, SUSE and Xamarin announced, in effect, the transfer of all things Mono to Xamarin.

The agreement grants Xamarin a broad, perpetual license to all intellectual property covering Mono, MonoTouch, Mono for Android and Mono Tools for Visual Studio. Xamarin will also provide technical support to SUSE customers using Mono-based products, and assume stewardship of the Mono open source community project.

Xamarin is a startup formed by Mono founder Miguel de Icaza following the acquisition of Novell and SUSE by Attachmate, which ceased Mono development.

Attachmate acquired Novell in November 2010. Mono has been plucked from the abyss with impressive speed.

That said, the strategy behind Mono has shifted. Mono exists because de Icaza liked what Microsoft announced back in 2000 when it introduced C# and the .NET Framework. Microsoft made a show of standardizing the .NET CLI (Common Language Infrastructure), which made PR sense at the time since there was controversy over Sun’s ownership of Java, though nobody really believed that Microsoft knew how to steward an open source development platform or indeed believed that it was really serious about it. History largely justifies that scepticism; but de Icaza called Microsoft’s bluff and forged ahead with Mono, implementing not only the CLI and C# but most of the .NET Framework as well.

The goal of Mono, as I recall, was to bring the benefits of C# and .NET to Linux developers, and to enable developers to move applications freely between Windows and Linux. Apple OS X was also on the radar, though it took longer to become much use. Recalling Mono’s early days, de Icaza said:

Mono to me is a means to an end: a technology to help Linux succeed on the desktop.

Mono worked remarkably well from quite early on, but never quite well enough to persuade mainstream developers it was a sensible choice for applications that would otherwise have run on Windows. It did emerge as a viable and productive toolset and platform for Linux and a number of Mono applications became popular, including Beagle search, Tomboy notes, and F-Spot photo management. Some ASP.NET applications run on Mono; I have one on this site. Another Mono success was its use as the scripting engine in Unity, a game development platform.

A big problem for Mono though was the lack of a business model. There was support and servicing of course, which must have generated some revenue for Novell, but most Mono use is free. Novell possibly had in mind that Mono could be significant as an application server, but it has never become a really trusted platform in the Enterprise. For example, as Alan Radding (Dancing Dinosaur) notes:

DancingDinosaur has not found any SUSE on z user that has successfully implemented .NET apps on the mainframe. A few have tried but reported that Mono on z wasn’t ready for prime time.

Even among the free software and open source community, Mono was hampered by suspicion of Microsoft. If Mono became successful enough to threaten Microsoft, would lawyers appear? Given the way Microsoft is currently behaving with Android, filing legal actions and signing up licensees, those fears might not be unwarranted.

So what is Mono today? The answer is that Mono is now primarily a mobile platform. The Xamarin home page makes this clear, as well as making it apparent that the Mono team has discovered the value of a business model:

Xamarin is tapping into two real business needs. One is the need for a cross-platform mobile development platform that works. The second is a way for Windows developers to use their existing C# skills for mobile development, given that they might not be happy with the tiny market share currently achieved by Windows Phone 7.

When I had a quick try with Monotouch I was impressed, and I would like to spend some more time with it and with Mono for Android.

Mono has touch competition though. In particular, PhoneGap, Appcelerator’s Titanium, and Adobe AIR. I was interested to see that Adobe is coming up with a packager for AIR on Android, which may significantly improve it as a cross-platform mobile toolkit.

Still, Xamarin is small and nimble and I expect it to succeed. It has also has Visual Studio integration, which is an advantage. One of the pieces Xamarin has now licensed from SUSE is Mono for Visual Studio.

The downside of these latest developments is that if you depend on Mono for the desktop or for ASP.NET, you may find these parts of the Mono project getting little attention from the new company. But Mobile is all that matters now, right?

I write this on July 19 2011. According to Wikipedia:

Recognizing that their small team could not expect to build and support a full product, they launched the Mono open source project, on July 19, 2001 at the O’Reilly conference.

Well, if there was a launch there it was low-key. It is not mentioned in this report. But de Icaza does recall:

We planned the announcement to come by July 19th 2001, so we could announce this at the O’Reilly conference, as Tim O’Reilly had been very supportive of this effort, and had offered his help since the early stages, when it was still a very young idea. When we announced the project launch we had our team in place, and we were shipping our metadata framework and our C# compiler as well as a few initial classes So officially the Mono project was launched on that date, but it had been brewing for a very long time.

Happy Anniversary!

SQL Server 2011 Denali publishes tables as Windows network folders

1 Comment

I’ve been testing the new Community Tech Preview of SQL Server 2011, codenamed “Denali”.

Here is an intriguing feature. You can now create a new kind of table called a FileTable. A FileTable is mapped to a folder on the filesystem, though you are not meant to access it directly once it is managed by SQL Server. However, you can access the folder in Windows Explorer, or over the network, as a network share. When you do this, a SQL Server component intercepts the Windows API calls and updates the FileTable. FileTables build on the existing FILESTREAM feature in SQL Server 2008, and the documents in the folder are stored as FILESTREAM data.

The illustration shows a folder in Windows Explorer that is also a SQL Server FileTable.

image

Is this the return of WinFS, the fabled relational file system which was originally planned for Windows Longhorn, but abandoned? Not really. According to the docs:

FileTables remove a significant barrier to the use of SQL Server for the storage and management of unstructured data that is currently residing as files on file servers. Enterprises can move this data from file servers into FileTables to take advantage of integrated administration and services provided by SQL Server. At the same time, they can maintain Windows application compatibility for their existing Windows applications that see this data as files in the file system.

Microsoft partners are not whooping and cheering for Office 365

2 Comments

There is a telling moment in the day two keynote at Microsoft’s Worldwide Partner Conference. “Now we’ve added Office 365”, says Corporate VP Jon Roskill. Do you guys feel the momentum?” There is a muted cheer, not the big whoop Roskill is looking for. “Now let’s have some momentum, whoo!” he repeats. Another barely audible cheer.

Why are partners not whooping and cheering?  Take a look at the Microsoft-commissioned Forrester report [PDF] on the total economic impact of Office 365. This report claims a remarkable payback period of only 2 months for a midsize organization moving to Office 365.

Looking at the figures in more detail, Forrester claims $54,000 saved over three years in eliminated hardware, $10,000 over the period in eliminated third-party software, $25,000 saved in web conferencing (Lync Online is bundled with Office 365), and $18,000 in “internal labor and professional services” saved on planning and implementation. There is an even bigger saving in support. Here I find it hard to puzzle out exactly what Forrester is claiming. It talks about “savings of $206,350 over three years” from simplified support and outsourced administration of infrastructure, but also refers to $146,250 costs in admin and support costs for Office 365; I am not sure if the $206,350 is a net figure. Forrester also throws in $260,625 saved on reduced travel thanks to online collaboration, which strikes me as highly speculative.

I suggest therefore that you do not take Forrester’s figures too seriously; but it is still worth noting that many of the savings come from revenue that would otherwise have gone to partners. How much partner income is lost will depend on the extent to which an organization outsources its IT admin, planning, support and administration, and on the margins partners achieve on things like third-party software; but it is considerable.

Of course there are also new business opportunities for partners. Presuming the savings from Office 365 and Microsoft’s other cloud offerings are real, a cloud-oriented partner has a strong sales pitch both to existing and new customers. Partners get an ongoing commission from subscriptions.

There is also an opportunity for new applications which link to cloud services. Yesterday Microsoft announced that the Windows Azure Marketplace, which used to offer data services and application building blocks, now also offers finished applications in US markets.

It is also true that Microsoft’s cloud offering is more partner-friendly than others, because it is a hybrid solution. Forrester’s report mentioned above assumes use of Active Directory Federation Services for single-sign on between on-premise and Office 365, a key feature which has been under-reported in the media coverage I have seen for Office 365. This feature, along with the fact that Microsoft’s server products like Exchange, SharePoint and Dynamics CRM can be deployed either online or as hosted services, means that there is flexibility over what is hosted and what is on-premise.

Nevertheless, it is hard to construct a reality in which the savings customers get from cloud services are real, without the further implication that total partner revenue will diminish, even though certain individual partners who take advantage of the new opportunities may end up winners.

This is true even if Microsoft succeeds in retaining all of its existing Microsoft-platform customers, rather than losing them to Google or other cloud providers. The consequences of a migration to Google, which is inherently not a hybrid platform, seem to me more severe.

Is there any way to put a positive spin on this, from a partner’s perspective? A couple of thoughts on this.

First, even if certain kinds of IT business are under threat from cloud migration, it is also true that the transforming impact of IT and the internet on businesses is far from complete. Much of what businesses currently do with IT can be greatly improved, there is still a thirst for new and improved business applications, and new technology including not only the cloud, but also massively parallel computing and of course mobile presents many new opportunities.

Second, it seems to me that partners should not be asking themselves how to maintain their business, but instead planning for change. It seems to me inevitable that the demand for skills in installing and nursing servers, deploying applications, and in maintaining and supporting clients, will diminish; and that is a good thing because these activities are IT plumbing and if they can be reduced it frees resources for other activities which have more business potential.

Behind the whooping and cheering, Microsoft’s message to partners is a tough one. Change, or die.

Google+, Bing social search, and internet monopolies

3 Comments

The big new thing in social media right now is Google+, the search giant’s latest attempt to grab a slice of the social internet from Facebook and Twitter.  I have been trying it for a few days and like everyone else have enjoyed playing with circles, the ability to categorise contacts into groups and choose who you sharing with. I like that it addresses a core issue, the fact that we want to share different things with different people, but dislike the added complexity. In practice, if I have a personal message I am likely to use email or some other form of direct messaging, whereas what I post on a social networking site I will likely address to everyone.

Still, Google+ is a decent effort, and irrespective of how it compares in detail to its rivals, I think it may take off simply because Google has other properties, specifically Google search and Google Android, which will point you to it.

The value of social networks to a search company was highlighted this week, not by Google but by Microsoft at its Worldwide Partner Conference. The opening keynote was short on big news, but did include a demo of new features in Bing, that other search engine.

Stefan Weitz Director of Influentials, showed how Bing can interact with Facebook so that you search results are annotated with the preferences of your friends. Here, Weitz has searched for “Mango” and Bing shows a section of results marked as Liked by your Facebook friends:

image

He then searches for Hawaii hotels for kids and sees this:

image

Once again, he sees two of his own contacts who have Liked a specific web site. He can go to the site with more confidence, or even click the name to interact directly with his contact and find out more.

This is powerful stuff, though the examples are contrived, and this is only going to work if you and your contacts do many of the same searches with the same search engine. The Microsoft/Facebook alliance has an advantage over Google in that Facebook has a bigger and more mature social graph; but Google has the advantage of a far larger search share, especially outside the USA. On this site, for example, here are the figures for July:

  • Google 90%
  • Bing 3.7%
  • Yahoo! 3.4%

You can figure out how much that leaves for “Other”.

Another Bing move also merits reflection. Weitz went on to demonstrate how Bing wants to you to do the transaction as well as the search on its portal. It is actually fine for Bing to do this with its small market share; but I am not sure that I like the implications for search in general.

This hints at my central concern, which is monopoly. One reason I like Twitter is that I have no sense that Twitter wants to take over my digital life. I know Google does; it wants my searches, my email, my documents, my music, my location, and now my friends.

I know Facebook wants a big slice of it too; it wants me to live inside its walled garden.

These thoughts chime for me with another incident from the last few days. I posted something  for sale on eBay, the dominant online auction site, and found that it has notched up its terms and conditions with me further in its own favour by insisting that I set up automatic payment of its fees before it would allow me to post the item. It also happens that PayPal, owned by eBay, has recently sent me a notice advising that it is restricting the number of sales that can be funded by credit card, I presume because it dislikes the consumer protection gained by buying by credit card.

The connection here is that eBay and PayPal only have the liberty to make these unilateral changes in their terms because of lack of competition. Yes, there are other online markets; but if you actually want to sell stuff, there is little real-world choice. Well, there is Amazon; and there is another organisation which, for all its many merits, is constantly extending its reach.

It is curious in a way, that when the web first appeared it seemed to be a great opportunity for the little guys – because on the Internet, nobody knows you’re a dog – but what we are now seeing is that winner-takes-all applies to a degree which goes beyond anything in the bricks and mortar world.

The frustration of developing for Facebook with C#

I am researching a piece on developing for Facebook with Microsoft Azure, and of course the first thing I did was to try it out.

It is not easy. The first problem is that Facebook does not care about C#. There are four SDKs on offer: JavaScript, Apple iOS, Google Android, and PHP. This has led to a proliferation of experimental and third-party SDKs which are mostly not very good.

The next problem is that the Facebook API is constantly changing. If you try to wrap it neatly in an SDK, it is likely that some things will break when the next big change comes along.

This leads to the third problem, which is that Google may not be your friend. That helpful article or discussion on developing for Facebook might be out of date now.

Now, there are a couple of reasons why it should be getting better. Jim Zimmerman and Nathan Totten at Thuzi (Totten is now a technical evangelist at Microsoft) created a new C# Facebook SDK, needing it for their own apps and frustrated with what was on offer elsewhere. The Facebook C# SDK looks like it has some momentum.

C# 4.0 actually works well with Facebook, thanks to the dynamic keyword, which makes it easier to cope with Facebook’s changes and also lets it map closely to the official PHP SDK, as Totten explains.

Nevertheless, there are still a few problems. One is that documentation for the SDK is sketchy to say the least. There is currently no reference for it on the Codeplex site, and most of the comments are the kind that produces impressive-looking automatic documentation but actually tells you nothing of substance. Plucking one at random:

FacebookClient.GetAsync(System.Collections.Generic.IDictionary<string,object>)

Summary:
Makes an asynchronous GET request to the Facebook server.

Parameters:
parameters: The parameters.

Another problem, inherent to dynamic typing, is that IntelliSense (auto-completion in Visual Studio) has limited value. You constantly need to reference the Facebook documentation.

Finally, the SDK has changed quite a bit in different versions and some of the samples reference old versions.

In particular, I found it a struggle getting OAuth authentication and access token retrieval working and ended up borrowing Totten’s sample code here which mostly works – though note that the code in the sample does not cope with the same users logging out and logging in again; I fixed this by changing his InMemoryUserStore to use a ConcurrentDictionary instead of a ConcurrentBag, though there are plenty of other ways you can store users.

I’m puzzled why Microsoft does not invest more in making this easier. Microsoft invested in Facebook and it is easy to get the impression that Microsoft and Facebook are in some sort of informal alliance versus Google. Windows Phone 7, for example, ties in closely with Facebook and is probably the best Facebook phone out there.

As it is, although I prefer coding in C# to PHP, I would say that choosing PHP as the platform for your Facebook app will present less friction.

HP breaks 2.5 million web support links

2 Comments

The internet and search: the greatest resource ever for troubleshooting computer systems.

Except when you follow a promising link to find this:

image

On June 26th, the HP IT Resource Center forums were migrated to the HP Enterprise Business Community. This migration coincided with the release of the new HP Support Center, and the retirement of the legacy ITRC support portal. As part of the transition, we have migrated all ~2.5 million posts and ~712k users from the ITRC forums into the new community site.
As a result of this transition, all links/bookmarks/search results that attempt to load an ITRC forum page will redirect to this announcement page.

I understand the reasons; but I wish companies would think twice before doing this. Or three times. Eventually the search engines will stop listing the broken links, but other references to these support discussions will still be broken.

How much would it cost HP to keep the old links online in read-only form?

It is not just HP of course. These generic “sorry, we broke the link” pages pop up regularly on Microsoft’s site, for example, often after following a link on Microsoft’s own site.

The web is designed to tolerate broken links; it is one of the reasons why it works. However, that is no reason to break them with abandon.

ReSharper 6.0 arrives: intelligent editing and decompiling for Visual Studio

JetBrains has released ReSharper 6.0, an add-on for Visual Studio 2008 and 2010 that delivers a remarkable range of tools, mostly focused on code editing and static analysis. There is also a unit test runner and a source code decompiler.

The heart of ReSharper is refactoring, hence the name, and it adds a large number of refactoring options to Visual Studio. These are nicely integrated with the editor, not only as right-click menu options, but with light-bulb suggestions that appear automatically. Here, for example, ReSharper is telling me that I could use implicit type declaration, and offering to make the change for me, or alternatively to suppress this type of suggestion forever if I do not like it:

image

Source code decompiling is also nicely done. In the above code, IClaimsIdentity is part of the .NET Framework so the source code is not normally available. With ReSharper though, I can navigate to decompiled source:

image

This could be legally sensitive, so I have to pass a Decompiler Legal Notice in which JetBrains attempts to disclaim liability.

image

Then I am in, though the results are not exciting in this instance:

image

If you only want the decompiler, you may find the free dotPeek is all you need.

The what’s new list in ReSharper 6.0 is long. It includes support for JavaScript, ASP.NET Razor, CSS and HTML, better XAML support including creating properties and dependency properties from usage, and macros for file headers which automates things like inserting current date and time.

The pricing is not excessive: in the UK it costs £148 for a personal license or £259 for a commercial license. If you think ReSharper will save you time and improve your code quality, which it likely will, it will soon pay for itself.

Internet Explorer 10 Platform Preview 2 gets web workers, HTML5 sandbox

Microsoft has released Internet Explorer 10 Platform Preview 2 which adds a number of features. These include:
  • Web Workers for background JavaScript.
  • File Reader API
  • HTML 5 drag and drop
  • CSS3 positioned floats
  • HTML 5 sandboxing
  • Some features of HTML 5 forms
I asked Microsoft’s Ryan Gavin and Rob Mauceri why IE seems so far behind its rivals in HTML 5 support if you look at a test site such as html5test.com, where IE9 scores 141 and Google Chrome 329. I was given several reasons. The site does not cover CSS3, SVG, yet does include “specs that are still under development, specs that have been superseded by other things, you have look at what it is actually testing,” said Mauceri. He added that the site only tests for the existence of the feature rather than how well it is implemented.
Fair points, but my sense is that Microsoft, while hugely ahead of where it used to be in terms of HTML standards support, is likely behind Google and Mozilla and likely to remain so. Microsoft has a slower release cycle, and a greater burden of legacy issues to worry about.
That said, Microsoft is pushing forward energetically compared to pre-IE9 days and the new features are interesting, particularly in the light of the greater role of HTML5 which has been promised for Windows 8.
Web Workers, for example, enables more responsive web pages through concurrent programming.
image
I also asked how Microsoft will enable greater access to the Windows API in Windows 8 without polluting the standards, but got the non unexpected answer “wait for the Build conference”.
No formal word on timing, but I would expect the delivery of IE10 and Windows 8 to be connected.

Office 365 and why it will succeed

1 Comment

Today is launch day for Microsoft’s Office 365, which offers use of Exchange, SharePoint and Lync hosted by Microsoft at commodity prices – not quite as low as $50 per user per year for Google Apps, but low enough that it is likely to be a substantial saving for most customers, versus the cost of installing, maintaining and backing up on-premise versions of the same software.

The debate about the merits of Office 365 versus Google Apps is a fascinating one, but the reality is that many organisations are not ready to give up Word and Excel, Outlook and Active Directory. Why?

  • They are too deeply invested in Microsoft’s platform, and depend on home-grown and/or third-party applications that run on it.
  • Office and Exchange is a business standard.
  • Desktop applications still have advantages for things like word processing or manipulating large spreadsheets.
  • Offline is important, and Microsoft is better at this than Google.
  • Microsoft ticks boxes in areas like compliance and archiving

The beauty of Office 365 is that migration from on-premise servers can be almost invisible to users. It is also an easy and effective solution for new businesses. Every mobile device seems to support Exchange, and one thing it has always done well is to synchronise nicely with multiple clients.

The other side of the coin is that Google Apps is by far the better option if you want to live in the cloud. Outlook Web App is not bad, but creating and editing documents entirely with Office Web Apps would not be fun at all. Office 365 will also be a struggle if you are inclined to ditch Windows. Email will be OK, and I guess Mac users have Office 2011, though in my experience that is inferior to almost any version of Office on Windows.

What about the really interesting questions? Is data more secure with Google, or with Microsoft? Is either platform resilient enough to manage without backups? What is the risk of extended downtime that could have a drastic impact on productivity?

Unfortunately it is not possible to offer precise answers to these questions, which I guess is why on-premise retains its appeal.

IE9 ActiveX Filtering causing tears of frustration

I have been assisting a friend who, she told me, could not get BBC iPlayer to work. Further, another site was telling her she did not have ActiveX, but she was sure she had it.

This was puzzling me. She described how she went to the BBC iPlayer site, and it said she needed to install Flash.

image

She clicked the link and got to Adobe’s download site. She clicked Download now and got a page describing four steps to install, but nothing happened, no download.

She clicked Adobe’s troubleshooting guide, which took her through uninstalling Flash Player and then a manual download. All seemed to work but at the end of it, it was the same. Go to the BBC site, and be told to install Flash Player.

You can understand how computers, at times, can seem downright hostile to the long-suffering user.

What was the problem? I logged on with remote assistance. Somehow, IE9 had ActiveX Filtering enabled.

image

This is actually a great security feature. ActiveX is disabled on all sites by default. A little blue circle symbol appears at top right.

image

Click this symbol and you can turn off filtering for this site only.

image

Yes, great feature, once you are aware of it – but too subtle to be noticed by the average user browsing the web. From the user’s perspective, no amount of uninstalling and reinstalling of Flash Player would fix it, and the PC was about to be flung across the room in frustration.

The other problem is that the feature is too new and too little used to feature in most of the troubleshooting guides out there. It is not mentioned in Adobe’s page on troubleshooting Flash on Windows and in IE, for example.

How the setting got enabled in the first place is a mystery. Maybe a mis-click. It is unchecked by default, and you can see why.

Conclusions? I guess it shows that security without usability is ineffective; and that minimalist user interfaces can work against you if they in effect hide important information from the user.

Incidentally, this is why  I dislike the Windows 7 feature that hides notification icons by default. It is user-hostile and I advise disabling it by ticking Always shot all icons and notifications on the taskbar.

It may be more secure, but I would not consider enabling ActiveX Filtering for non-technical users.
