Mono may implement Silverlight for Linux

Mono lead Miguel de Icaza likes Silverlight. He says:

It makes tons of sense for us to start looking at an implementation of Silverlight on Linux with Mono. There is already a XAML loader, it is the perfect excuse to use Antigrain for high-speed graphics and that only leaves the pesky media issue to be solved.

In fact, am kind of happy that Microsoft did not do the port themselves as implementing this sounds incredibly fun and interesting.

Microsoft should grab this offer, if it is serious about cross-platform. Although Linux currently only forms a small proportion of desktop operating systems, it is nevertheless significant; Ubuntu in particular is making a big impact. Mac/Windows only may be kind-of good enough for the USA, but that’s not the case worldwide.

Times Reader and offline Silverlight at Mix07

3 Comments

I’m attending a panel discussion on the WPF-based Times Reader, with Tom Bodkin, Assistant Managing Editor and Design Director at the New York Times, and media designers Roger Black, and Filipe Fortes.

Bodkin is talking about the Times Reader, which is sees as offering the best of both worlds – print and web. He is an enthusiast for the tablet PC, but prefers the smaller ones like the Fujitsu P1610 [I agree 100%, I’m on a Toshiba Portege M400 now, but still miss my old, smaller Acer C110]. He thinks that multi-purpose tablets have more future than dedicated devices like Sony’s reader.

He likes the fact that Times Reader publications feel like a publication – “it’s not webby”, he says. He’s showing off some of the features of Reader, including newer features like “news in pictures”, which is a slideshow of images, and the ability to add ink notes to stories when using a Tablet PC. “It’s a print publication plus”, he says. He demonstrates the intelligent reformatting that Reader provides. There’s also a great new search feature, which includes word search and a graphical topic map that shows related stories.

I asked about the cross-platform issue. According to Bodkin a Silverlight implementation is on the way, which includes most of the features in the full version, in “a matter of months.”

This intrigues me, as I had been told by some Microsoft people that Reader would be difficult to implement in Silverlight. Two obvious issues are the limited text features, and the lack of offline storage. There is isolated storage coming in Silverlight 1.1 (far more than a matter of months away), but this will be inadequate for Reader.

It turns out that Nick Thuesen is here, the lead developer for Times Reader. I spoke to him afterwards. He has a neat solution for Silverlight’s limitations. The plan is to use an embedded browser (Safari web kit) and to host Silverlight within that. This way, the native desktop app can handle offline storage; Silverlight becomes more like Adobe’s Apollo, a desktop rich internet application.     

Why not Adobe PDF? “There’s no reflowing, PDFs are really limited,” says Bodkin. “We had an electronic New York Times in PDF, but to read anything… it’s just impractical.” “And this can update,” adds Roger Black, “But the big thing to me is the type. How this will work in Silverlight is not completely worked out.”

Fortes talks about magazine publishing through a WPF Reader, with a more intensively visual appearance, embedded video, and community features like most popular articles, most popular ads. He is also saying that typical web content still lacks the sophistication that print provides (think fashion images, carefully designed text). I find this thought-provoking: is the Web really so bad for this? Clearly this is impossible for naked HTML, but when supplemented by Flash and/or clever CSS?

There’s discussion about the continuing bias towards metaphors that work in the print world but not in the web world. The suggestion is that we still have a lot to learn about how to present content electronically.

Bodkin says that the NY Times writes two sets of headlines; web headlines are more literal than print in order to work well for search engines. This reminds me of a post I made three years ago called Google edits the internet:

…how much of what we read on the Web is influenced by Google’s search and advertising algorithms?

Black talks about a problem with the Reader, which is its dependence on templates into which XML content is poured. Good though they are, this is restrictive in design terms, compared to the complete flexibility of print.

What’s coming in Times Reader? Bodkin mentions plans for video, downloaded on demand, and the possibility of interactive features such as those Fortes has described.

Finally the panel considers some of the business issues. Income from web sites such as nytimes.com remains only a tiny fraction of what is needed to run a newsroom with a global network of reporters; armies bloggers do not remove the need for professional journalists. If print is slowly declining (and I think it is – Thuessen mentions that he has never bought a newspaper), then the question of “who pays” is important and largely unanswered.

Sadly, I stopped using the Times Reader when it went pay-only.

Pay and play: how the Silverlight .Net runtime is kept small

Silverlight 1.1, currently in Alpha, will include a cross-platform version of the .NET runtime. The desktop version of this runtime is over 22MB, yet Microsoft is promising to keep Silverlight at around 4MB. How is this size reduction achieved? In part by stripping down the libraries to a minimal core, but Microsoft is also using another technique which it calls pay and play. This means that further class libraries are downloaded as needed, increasing the effective range of available libraries without impacting the size of the core runtime. Sleight of hand perhaps, but it does make sense for online apps.

Developers coding for Silverlight will need to know which of the libraries available in desktop .NET are also in the Silverlight framework. Because of pay and play, some will be in the core, some will be available on demand, and others will never be available. Apparently Visual Studio will give you a visual indication of which is which.

How big will the Silverlight runtime be if you include all the pay and play libraries? Here at Mix07, Microsoft’s Joe Stegman would not say, but I got the impression it will be substantially larger. Of course this is still Alpha; everything can change, and final decisions about what is core and what is pay and play are yet to come. Stegman was also uncertain about some aspects of delivery. You would imagine that pay and play DLLs would be downloaded from Microsoft’s servers, and that once downloaded they would be persisted and shared so that other applications can use them without a further download. Stegman says this is probably what will happen, but there seems to be some doubt.

The Silverlight 1.1 runtime will not be as small as it first appears.

Silverlight on the Mac: picture

Here at Mix07 we’ve seen some impressive demos of Silverlight running on the Mac. All the demos worked; the applications looked the same on the Mac as on Windows. Scott Guthrie showed “Silverlight Airlines”, which uses .NET code to call an ASP.NET web service. You draw a line between cities to show where you want to travel, select a date, and a grid populates with the available flights. Here’s my fuzzy picture, though I imagine the demo itself may be put online soon:

Silverlight with cross-platform .NET runtime announced, alpha download available

Microsoft’s Ray Ozzie and Scott Guthrie, here at Mix07, have announced the addition of a cross-platform .NET runtime within Silverlight, Microsoft’s browser plug-in for streaming video and rich internet applications.

I’m not sure this counts as a major announcement – after all, this very thing was talked about here at Mix last year. What is new though is that you can download the alpha from today, for Windows and Mac. Nothing has been said yet about timing, but I guess the fact that this is described as alpha implies a significant wait before a final release.

Nevertheless, this is a critical development for Silverlight, particularly as Adobe’s Flash now has a JIT-compiled Javascript runtime that in language terms is not that far removed from C#. Differentiation may be mainly in the runtime library that is available, and of course Visual Studio integration.

AppForge: a product activation nightmare

7 Comments

Nobody likes product activation, but it is used increasingly by software vendors in search of more effective anti-piracy measures. Microsoft is the most prominent example, but many smaller vendors do the same. Codegear, for instance, use activation for Delphi. Even if you have a valid registration key, you cannot use the product until it has checked in with Codegear’s license server.

Last month Appforge went bust. The company made a development tool called CrossFire, which lets you code in Visual Basic or C# but cross-compile for numerous platforms including Palm, Nokia’s Series 60 and Series 80, Blackberry and Windows Mobile. A useful tool, but AppForge has an activation system that applies both to the development tool and in many cases to the client runtimes.

The AppForge license server is now offline. Result: developers with CrossFire applications and fully paid-up licenses can no longer deploy their products.

AppForge has been acquired by Oracle, but apparently Oracle has no interest in continuing the CrossFire product. Here’s what Oracle says:

Please note that Oracle’s acquisition of AppForge’s intellectual property did not include the purchase of the company as a whole, or the purchase of other AppForge assets including its customer contracts. Accordingly, Oracle does not plan to sell or provide support for former AppForge products going forward.

Former customers are fighting back. There is talk of a competition to crack AppForge activation: money for the prize is being put on the table.

What about Oracle? Is it really so difficult to resurrect the AppForge license server? Ending all support and development for a product is bad enough; robbing existing users of the right to use it seems extreme.

There may yet be a happy ending. But for now, this really is the nightmare scenario that opponents of the product activation concept feared. No, I don’t think something similar could happen to Windows and Office; but clearly there are real risks when using products from smaller vendors.

A solution is to use some form of escrow where unlocked versions of the software are guaranteed to be made available in the event that the original company can no longer offer activation services. The AppForge saga suggests that customers should insist on this or some alternative protection before committing to activation-protected software.

Do you want Office in the cloud?

David Berlind has a series of interesting posts about Google apps versus Microsoft Office; the series starts here, more or less. Today there’s a related post from Dan Farber, who reports Microsoft’s claim (from Jeff Raikes) that there is little demand for Microsoft Office in the cloud.

Cloud-based applications have huge advantages – easy collaboration, zero install – but it happens that for me, there is little incentive to use Google’s Docs and Spreadsheets or the like. Cloud storage is more important than cloud applications. Cloud storage solves several problems including anywhere access and off-site backup. I also use an internet-based subversion repository that gives me document history. But I don’t need to use cloud applications in order to benefit from cloud storage. When out and about I usually work on my own laptop, not in internet cafes or on other people’s PCs. 

When I first saw Amazon S3 I knew immediately that it would be useful to me. When I saw Docs and Spreadsheets (and its predecessors like Writely), I was greatly impressed but had little reason actually to use the applications.

I am speaking personally because this will not be true for everyone. For some, the collaboration and zero install benefits of cloud apps will be more significant than they are for me. Further, these online applications are also an easy route to cloud storage; I realise that not everyone wants to mess around with S3 or Subversion. There is friction in having to think about where to save a document. With online applications that friction is removed.

What if Microsoft made cloud storage as seamless in Office as it is in Google Docs and Spreadsheets? It is surprising that an option to save to Windows Live is not built into Office 2007. Of course there is Sharepoint, whichI presume is the underlying platform for Live storage, and there is Groove, but the average home or small business user won’t have these set up. There are a couple of mysterious options in Word, under the Publish menu, for saving to a Document Management Server or creating a Document Workspace. They don’t do much out of the box. There is no wizard to help users create a new free Live account, with extra space and features for subscribers, for example.

There is also the question of bloat, which Berlind considers here and here. This is one of those things you don’t care about, until you do. I don’t care about bloat if an app performs well and the unneeded features are not in my way. I do care when it turns into an Outlook 2007 debacle. You run Outlook; then you run Thunderbird; and you see the downside of bloat. Word and Excel? Not an issue right now, they hum along fine.

So what does next-gen Office look like? Is it an improved Docs and Spreadsheets? Or Microsoft Office/Open Office plus cloud storage? I’m interested in opinions.

Why I’m not using Google Web History

1 Comment

Google Web History has two main benefits.  First, it enables smarter search. Google can take account of which pages you visited, presumably giving greater weight to sites where you viewed numerous pages rather than diving in and out quickly. Second, you get a nice Google-ised search of pages you’ve viewed, instead of attempting to find what you want in the history list of links, in IE or Firefox.

So why not? First, because Google has enough of my data already. I use Google for search, because I find it the best search engine more often than not. I use a Gmail account occasionally. I use Adsense. I’m experimenting with Docs and Spreadsheets. That will do.

Don’t I trust Google? Sort-of. It has a good track record, as far as I know. And it is not that I have anything particularly to hide. Still, the AOL disaster last year was a warning flag. And I do read the privacy policies, and don’t find them reassuring.

There’s a second reason. To sign up for full Web History, you need to install the Google Toolbar. This is how Google gets a record of pages you visit beyond your searches. However, I have a minimalist approach to add-ons, especially those which run all the time. My reward is a more stable and better-performing operating system. So I would need a strong reason to install the Toolbar, and I don’t have one.

There’s more. When you are invited to install the Toolbar, you are given an opportunity to read Google’s terms of service. Despite its generally excellent usability elsewhere, the big Goog doesn’t make it easy to read this document. The terms of service are in a narrow scrolling window. I recommend that that you Select All, Copy, and then Paste into your word processor. It comes to 14 pages in Word:

Except – here’s something strange. If you get to this page in FireFox, you get the general terms of service as mentioned above. If you get to this page in IE, you get a different document, which is for the Google Updater and the Google Pack:

The document is actually shorter than the general terms, but not good news if you like to keep control of your PC:

The Software may communicate with Google servers and/or Third Party servers from time to time to check for available updates to the Software, such as bug fixes, patches, enhanced functions, missing plug-ins and new versions (collectively, “Updates”). By installing the Software, you agree to automatically request and receive Updates.

There’s a similar clause in the general terms, but without the reference to third parties. Further, in this document you agree to stuff from Adobe, Real, Skype, Symantec and others. In practice I’m sure you can install the toolbar without all these other pieces, but still … this is a big red flag from my perspective.

As an aside, I wonder if corporate legal departments ever make the connection between what employees may be agreeing to online, and their normal legal policy? Put another way, what if I copy this agreement into an email, fire it across to legal, and ask, “Is it OK if I agree to this?” Complete with some wide-ranging indeminities, limitations of liability, non-warranties, and in some cases, the right to install stuff on your computer without asking again?

Bottom line: I’ll live without Google web history.

How not to get support

I’ve had four successive emails of increasing urgency from someone using my simple sqlite wrapper.

It’s sometimes difficult to handle such requests – the code is free and there is a limit to how much time you can give away – but in this case I’m unable to reply. The sender is using an email address that is not valid on the internet; the domain ends .local and it is not obvious what the real email address is.

If that’s you – please reconfigure your email client and try again.
