Amazon Silk: fast cloud-powered browser, or a new way to mine your data?

3 Comments

Amazon announced its new range of Kindle devices today and the web is buzzing with debate about the impact of the new Android-based Kindle Fire tablet on Apple and others.

Amazon knows how to pile high and sell cheap, and can make money from content even if it gives away the hardware, so it is a strong contender in this space.

The real innovation announced today though was in the web browser. Amazon announced Silk, which splits the browser between your Kindle Fire and EC2 (Elastic Compute Cloud).

Amazon’s point: it can hold a massive cache of web content on EC2, as well as performing common-sense optimizations like scaling images to an appropriate size before sending them to your device.

Is this really new? Much of it sounds familiar, if you know about caching and proxies. Nevertheless, Amazon is in a strong position with its large cloud resource, and can design the web browser specifically for its cloud proxy. In addition, it knows the exact size and capability of the device. And perhaps its smart engineers have come up with better ways to cache. One feature is predictive caching – sending down the page it things you will visit next, before you actually go there.

There are some hard problems, as I have found in trying to optimize my own web site. Caching dynamic content, so that PHP script does not get executed by every browser request, is an obvious thing to do; but web pages draw content from multiple sources, including scripts that serve ad content that is meant to be targeted for the specific viewer. Optimizing that is harder.

It does also occur to me that a side-effect of Silk is that every single bit of browsing you do will go through Amazon and could potentially be mined for data about your browsing habits. Amazon, naturally, is well-placed to send you related ads from its own retail site. Amazon has not mentioned this aspect, but I am sure it has been thought about.

A few observations on Windows Phone 7.5 “Mango”

2 Comments

I received a Windows Phone running version 7.5 “Mango” for review yesterday. Here are some initial observations; I am not going to call it a review after such as short time.

image

There is still no screen capture utility – well, there is this one but it requires a developer accounts. So no screens, sorry. Microsoft should fix this – how difficult can it be?

Microsoft says there over 500 updates in Mango, and it does feel like a significant update, though retaining the look and feel of the first release. A half-version upgrade is about right.

Some things I noticed:

  • Task switching. Press and hold the back button, and swipe through running apps. This is excellent, better than iPhone or Android.
  • Voice control. This is expanded in Mango to include web search, text messaging and more. Tip: to see the commands, hold down the Windows key to go into speech mode, and click the help icon.

    It has great potential, especially with a bluetooth headset for true hands-free. I have a Plantronics Voyager Pro bluetooth headset, reviewed here. Using this guy, I can press and hold the call button on the headset, to put the phone into speech mode.

    I found this works well for calling people or simple searches, but general speech to text is not too good. I tried texting someone the message “Your parcels have arrived”. After several attempts, all of which were interpreted as various strings of garbage starting “George”, I gave up. I would still use it for making calls though; it seems that when the scope is narrowed to people in your contacts list, the interpretation is more reliable.

  • The search button is no longer contextual – it always takes you to Bing search. I think this is a retrograde step.
  • Local Scout is a feature that is meant to find restaurants, shops, things to do, and other handy information based on your location or the current map location. This is a neat idea, but when I tried it for my home town it did not work well. The first problem: I found that tapping the Local Scout tile is unreliable, and sometimes reports that Bing cannot find the location even when the location button in Bing Maps works fine.

    Fortunately you can also use Local Scout from Bing Maps. The Local Scout listing was not good though. Of the top 20 food and drink places, one had been closed for years, others were duplicated under old and new names, and there were hardly any ratings or reviews. Tap “Suggest changes” and you can submit changes to the address details or report closure, but you cannot add a review or rating, which seems a severe omission.

    I downloaded the TripAdvisor app which is a great deal more useful, mainly because of the amount of user-generated content.

    Maybe I’m missing something, but it seems to me that Microsoft needs to join a few dots here; Local Scout is only as good as its data.

  • Office and SharePoint integration. As soon as I gave Windows Phone my Live ID, it picked up my SkyDrive account and was able to open, edit and save documents there. I also hooked up Outlook to my own Exchange server, and added an Office 365 SharePoint account as well.

    SkyDrive support is new and a huge feature, especially considering that it is a free service. Editing features on the phone are limited, but you can include basic formatting.  More important, you can easily access what could be a large document repository.

    OneNote support is good, and notes made on your phone sync automatically to SkyDrive, where you can further view and edit them in a browser, or in desktop OneNote. I guess I can show a grab of the browser, which shows that the voice memo is inaccessible:

    image

    I discovered a few oddities. I was unable to link Windows Phone to my own SharePoint 2010 test server, receiving a message “We don’t support this authentication scheme”. Later I found this information:

Unless your organization uses a Microsoft Forefront Unified Access Gateway (UAG) server, you can only access a SharePoint 2010 site if you’re in the office and connected to your organization’s Wi-Fi network.

That is a considerable limitation. It did work OK with SharePoint on Office 365, except that for some reason I can find no way to create new documents on Office 365 – well, maybe in the browser. The Office Hub can create new documents on SkyDrive, but not on SharePoint, which is odd as the two have a lot in common.

Despite these issues, you get a lot out of the box for using Office on the move, particularly if you use a supported SharePoint configuration or SkyDrive. The on-screen keyboard is good too.

  • Music search. This is a fun feature. Go to Bing search, click the music icon, and it will try to recognize what is playing. It had no problem finding Katy Perry’s Teenage Dream. It struggled a bit with the more obscure Strangely Strange but Oddly Normal by Dr. Strangely Strange; but on the second attempt it found that too.
  • The social media features seem strong to me, though you are limited to the baked-in services which are Twitter, LinkedIn, Facebook and Windows Live (no Google+). You do have to link each service to your Live ID for full features; for example, you give permission to Windows Live to post to your Twitter account. The integration is smooth and if you spend your time juggling with these four services then this may well the phone for you. For example, you can post a message to all of them at once. I found the People hub good enough as a Twitter client.
  • Apps are still lacking. The issue is not the quantity of apps available, but their quality, and the lack of certain key apps. There is no official Dropbox app, for example, so you will need to use the web or a third-party workaround. On the positive side, the free Guardian app is great, especially since you can pin a section to the Start screen – I did this for Technology – and there are apps for WordPress, Amazon Kindle, the ubiquitous Angry Birds and some other essentials.

    I noticed that TripAdvisor has 61 ratings on the Windows Phone Marketplace, whereas the Android version has 39,930. That illustrates the scale problem Microsoft is facing.

  • Still no Adobe Flash.
  • Microsoft’s new Windows Phone site is clean and informative. Not always the case with Microsoft’s sites. The My Windows Phone site lets you find your, lock or erase your phone, once configured.
  • Internet sharing, which makes your phone into a wireless hotspot, is coming but subject to operator support and approval. This means you will likely pay extra for “tethering”. I have a free app which does this on my Android phone and find it useful, though whether it is worth paying extra every month is another matter.
  • Microsoft has introduced some features aimed at enterprises. In particular, Information Rights Management is now supported for Outlook and Office mobile documents. Another important feature is the ability to deploy custom applications as hidden apps, which do not appear in Marketplace searches, but can be downloaded from a link circulated internally. There is now a Lync (business messaging and conferencing) client for both Office 365 and on-premise Lync servers.

Future of Windows Phone?

My guess is that Microsoft is badly disappointed by the sales performance of Windows Phone to date. The problem is not so much the phone itself, but that it has failed to convince either the operators, or the retailers, or the general public, that it is something special and worth choosing ahead of either an Apple iPhone or Google Android device. In fact, typically retailers have few if any Windows Phones on display, and even customers asking specifically for one may be redirected to something else. The truth is, there is a disadvantage in having a minority-choice device, most obviously in the selection of apps available, but also in features that rely on user-generated content.

I asked about this problem at the Mango press launch and was told that the Nokia partnership will be the solution.

My review device is a first-generation HTC Trophy, and while it is decent enough it is not outstanding. Give Windows Phone some truly desirable hardware and a few must-have apps, and its fortunes will change, but that is not an outcome that I take for granted.

I do like the SkyDrive and Office 365 integration though, with the caveats noted above, and if I were Microsoft I would be pushing the value of those features.

The Adobe Flash and Windows Phone 7 mystery

2 Comments

I attended Microsoft’s Mix event in March 2010, where Microsoft gave us the first detailed preview of Windows Phone 7 from the developer perspective. At that time, Microsoft made it clear that the Adobe Flash plug-in would not be supported in the first release, but implied that it would follow.

Did Microsoft ever announce that Flash support would definitely come? I am not sure that it was quite promised, though I do recall Microsoft spokespersons including Charlie Kindel explaining that native code development would not be possible for developers, other than for operators customising the device – the HTC Hub is an example – and for Adobe building Flash.

Adobe’s Mike Chambers did state that:

Adobe and Microsoft are working together to bring Flash Player 10.1 to Internet Explorer Mobile on Windows Phone 7 Series

In June, still pre-release, I spoke to Adobe’s Michael Chaize who told me that work on Flash for Windows Phone 7 was well advanced and that it would follow “within months” of the initial release.

There has also been contrary evidence. Microsoft’s Andy Lees explained to Mary Branscombe:

There is no ActiveX plug-in extensibility [in the browser] because of the security model; we’re not going to do that. And with no ActiveX plug-in model, how would we do Flash?

Fair enough and even sensible, but why did Microsoft imply earlier that Flash was on the way if in fact the security architecture made it impossible? Plans change of course, but I have never been able to get a clear statement on the matter other than vague expressions of cooperation between Adobe and Microsoft. Like this one from Microsoft’s Joe Marini:

We are working with Adobe, but it has not yet been decided the last time I checked – part of that is Adobe is doing what they have to do and we’re doing what we have to do. The last I checked the team is working with them but I don’t think they have any announcement whether it’s going to definitely work or not.

Now Microsoft has just released Windows Phone 7.5 “Mango”, the first major update to the the Phone OS, and Flash is still not supported. Either because Adobe has not yet done “what they have to do”, or because Microsoft has not done “what we have to do”, or because the architecture prevents it, who knows?

You can debate of course whether Flash support is a selling point or a burden for a smartphone – but it would be good to have clarity on the matter.

My own best guess is that if it has not come by now, it never will. Although Microsoft will not say so, for obvious reasons, I also think it is inevitable that the Windows Runtime and the Metro-style development model found in Windows 8 will form the operating system for a future Windows Phone, though I am not sure if it will be Windows Phone 8 or later, but that will change the rules. Currently IE in Metro does not support plug-ins, so I would say the prospects for Flash in the browser on Microsoft’s phone are not good.

What about Adobe AIR for Windows Phone? Interesting question, though it might be difficult given that Adobe would have to in effect create a Flash to Silverlight conversion tool which might hurt a bit. This would be easier on Metro since native code development is supported.

Adobe’s MAX conference is on next week so there may be further information on this long-running topic then.

Miguel de Icaza talks about Windows 8 and the failure of Linux on the desktop

29 Comments

At Microsoft BUILD earlier this month I arrived early to hear Anders Hejlsberg talk about the future of C#, and found myself next to Miguel de Icaza, co-creator of the GNOME desktop and of Mono, the open source implementation of Microsoft .NET. I took the opportunity to ask a few questions, which I have his permission to post.

I recall that when .NET was first announced in 2000, it was not long before de Icaza announced Mono. I was interested therefore to know his reaction to Windows 8 and the new Window Runtime which powers “Metro-style” apps. Will we get an open source implementation of Metro-style on Linux?

I don’t think so. To be honest, with Linux on the desktop, the benefits of open source have really played against Linux on the desktop in that we keep breaking things. It is not only incompatibilities between Red Hat, Unbuntu, Suse, but even between the same distribution.  Ubuntu from this week is incompatible with the one nine months ago. And then there are multiple editions, the KDE version, the Gnome edition, the one that is the new launching system.

When you count how many great desktop apps there are on Linux, you can probably name 10. You work really hard, you can probably name 20. We’ve managed to piss off developers every step of the way, breaking APIs all the time.

I’m heartbroken, that’s the bottom line.

What about compiling your Metro app for iOS or Android?

I think that Linux has a tough time on the desktop. And the desktop is starting to not matter any more. On the other hand, building WinRT is going to be a significant amount of work. A large chunk probably could be reused from Moonlight. But it is a lot of work, to be able to reuse existing Windows apps, and in the case of iOS they already have their own stack, and Mac has its own, Cocoa is really nice and we have .NET bindings for it.

So I think we’ll learn interesting lessons from Metro. There is stuff that will be useful on other platforms like the JSON reader. But I’m not going to spend any time on WinRT for other systems.

And we can speculate about how well Metro will work in the market …

They are Microsoft, it’s going to succeed. In three years they are going to have this thing on half a billion computers, so it will be out there.

It seems like they are going to use their muscle for two things. It’s going to be a tempting space [for developers], but if you want to go into the right distribution channel for that half a billion computers, you need to abide by the Metro guidelines. They are not going to give you full API access, they are going to give you the sandboxed version. Which is good, because it can finally fix the security problems on Windows. They are going to use their muscle to reset the rules for Windows.

Especially on ARM

Right, and it is needed, they definitely need to fix this mess, a lot of malware, spyware, and the fact that everybody is sysadmin, and has to reinstall their machine every so often.

I’ve heard the word “safe” a number of times.

Right, and think of an iPad, you don’t need to be a sysadmin.

Now, you could argue that by WPF not being available to everybody and being bound to .NET they limited the effect WPF would have had, whereas Metro gives this to C++ developers, but they’re saying, hey, you can’t call Win32, there is all the Win32 stuff you can’t call. You have to use Metro. So they might be repeating that [mistake], but maybe it’s eclipsed by the fact that there’s going to be a rush to the app store. It seems like there is a big enough carrot now.

How are you getting on with the Windows 8 tablet?

I have to say, I actually like Windows 8. I am not a Windows user. It’s probably the first time that I would use a Windows machine.

Miguel de Icaza is now at Xamarin, providing cross-platform tools for using C# and .NET to build apps for Apple iOS and Google Android.

Android tablets ahead of Apple iPad on Amazon

Following Gartner’s report on the expected dominance of Apple’s iPad2 in the tablet market throughout 2011 I took a quick look at Amazon’s sales and user ratings.

My guess is that Apple stores and direct sales online account for a large proportion of iPad sales, so no doubt the iPad is ahead overall. Even so, I was interested to find  the iPad at number 7 on Amazon.co.uk, not only below three cheap 7” cheapies from little-known brands, but also below the Asus EeePad Transformer and the Samsung Galaxy Tab 10.1, both of which are at iPad-like prices.

image

Buyers on Amazon.com seem to have less enthusiasm for the cheapies. At the time of writing, bargain prices have pushed HP’s discontinued TouchPad to number 1, followed by the EeePad and the Motorola XOOM. Apple iPad is at 4, with Galaxy Tab 10.1 at 5 and 6.

When you see nearly 500 user reviews and a four star average rating, as for the Eee Pad, it shows that these things really are selling and being enjoyed.

Of these I have only properly tried the TouchPad and the iPad. I did not much like the TouchPad, though apparently firmware updates have considerably improved it.

The closest I got to Windows on ARM at Microsoft BUILD 2011

A couple of the stands in the exhibition at Microsoft’s BUILD conference last week were showing Windows on ARM. This one was on the NVIDIA stand and was most likely running its Tegra 2 SoC (System on a Chip) though Tegra 3 (code-name Kal-El) is apparently now in production. The tablet was displayed under a plastic shroud which could only be lifted when someone from Microsoft was present, though I was able to get this snap of the machine sans shroud. I was not permitted to handle the machine.

image

I have blanked out part of the background because it was black on black.

My main observation: it looks just like the Intel version. This screen shows a Metro app running side by side with the Windows desktop, and showing the “charms” on the right.

Gartner reports that Apple will have the tablet market almost to itself in 2011 (73.4% market share). I believe Windows on ARM is critical to Microsoft’s strategy to compete. In principle, it should be cheaper and more efficient than an Intel device, and one that is more locked-down in the style to which Apple has made us accustomed.

If Microsoft and its hardware partners can get the size, weight and design details right, I suspect I would rather have a Windows 8 tablet than an iPad. One advantage is the ability to have two apps side by side. Microsoft’s new user interface works really well with touch. I will expect to find a Windows remote desktop client there by default, and better support for Microsoft Office and SharePoint than I find in the iPad.

By the time Windows 8 comes out though, we will likely have iPad 3 with who-knows-what improvements; Apple has all the apps; and breaking into this market will not be easy.

Appcelerator opens component marketplace for mobile developers

Appcelerator has launched its Mobile Marketplace, offering software components for mobile and web developers using Titanium, Appcelerator’s cross-platform toolkit for Apple iOS, Google Android, and others – though only iOS and Android seem to be supported in the Marketplace currently.

image

Developers create modules using the Titanium Module SDK, and get 70% of revenue.

I took a quick look and found it thought-provoking. I am a fan of user reviews, and one nice feature of the Mobile Marketplace is that it supports reviews and ratings. Finding out what other developers think of a particular component often involves trawling through Google searches, asking on forums and so on; a marketplace with authentic hands-on reviews has real value.

That said, when I checked out an example, LucidChart, which is a diagramming component with 5 star rating and four reviews, I was not impressed with the review quality, and puzzled that some of the reviews date from July, before the Marketplace opened. Still, developers can make their own judgment about the reliability of a particular review.

Many of the components are on a monthly subscription, on a per seat, per month basis. Some developers are uncomfortable with this model and the likely costs:

… charging such high monthly fees is a complete rip off. My entire Apple developer license only works out at $8.25, are you seriously thinking that a module is worth more than what Apple provide to developers for a fraction of the cost?

Another issue is that some of the products are not really code components, but developer services like TeamworkPM.

Some components are free though, and if the Marketplace attracts a reasonable level of traffic and interest then it could prove an excellent resource for Titanium developers.

Adobe to ship Flash 11 and AIR 3, repositions Flash vs HTML 5

Adobe has announced that Flash 11 and AIR 3 will ship in early October.

There are significant changes in this release.

  • Flash gets Stage 3D (previously codenamed Molehill), a set of low-level 3D APIs, GPU accelerated where hardware allows, which will make console-like 3D graphics and games possible in Flash. Stage 3D wraps DirectX on Windows and OpenGL on desktop and mobile platforms.
  • 64-bit Flash is here at last, supporting 64-bit Internet Explorer and other browses on Windows, Mac and Linux.
  • AIR, which uses Flash as a runtime for desktop and mobile applications, now supports native extensions for better device support, operating system integration, and the ability to speed performance-critical code or use open source libraries.
  • In addition, the AIR packager for iOS, which lets you wrap your application as a native executable, is now a feature called Captive Runtime which is available for Windows, Mac and Android as well as iOS. Users who install a packaged application will not know it uses AIR, and will not need to install or update the AIR runtime as it is packaged with the application, though it is not actually a single file (on Windows at least).

These new options make the Flash and AIR combination an interesting comparison with other cross-platform development tools, such as Embarcadero’s new Delphi XE2, which targets Windows, Mac and iOS with a new framework called FireMonkey; or Appcelerator’s Titanium tool for cross-platform desktop and mobile development. Note though that Adobe is not promising any performance improvement. This is just another way to package the same runtime.

Adobe’s advantage is its high quality design and development tools and the maturity of the Flash runtime. For application size and performance, it will likely fall short of true native development tools. The ActionScript language could do with updating, and I would not be surprised if Adobe addresses this in the next major Flash release.

But do we still need Flash? Flash in the browser is in decline, thanks to the influence of Apple and the rise of HTML 5. Adobe’s MAX conference is coming up soon, and I noticed in the schedule [Flash needed] a defensive note in some of the sessions; there is even one called “The Death of Flash” which talks about “the misinformation that’s percolated through the web over the past year”.

That may be so; but even Adobe is re-positioning Flash and recognizing the rise of HTML 5. “Customers see significant advantages for Flash in a few focused areas,” said Adobe’s Danny Winokur, VP and General Manager of Platform , in a press briefing. He identified these areas as gaming, media apps, and “sophisticated data-driven applications” – think data visualisation rather than just forms over data. “For everything else it is very clear that … HTML 5 is a mature enough technology that it is a really good solution.”

Adobe is therefore investing in HTML 5 tools as well as Flash tools, and Winokur mentioned the Edge motion design tool as well as the venerable Dreamweaver.

I asked Winokur, given that HTML 5 is maturing fast, how Adobe sees the picture vs Flash in say two years time. He replied that Adobe is actively working to advance HTML 5, but that “there will continue to be opportunities for innovation in Flash, where we can … enable new possibilities that did not previously exist on the Web.” He makes the case for Flash as a kind of leading edge for HTML, with features that eventually become part of the HTML standard.

It is a fair point, but it is obvious that the niche for Flash is getting smaller rather than larger.

Adobe has never charged for the Flash runtime, and while the Flash vs HTML path is tricky to navigate, Adobe mainly makes its money from design tools, server applications and web analytics, and while Flash plays some client role in many of these products, Adobe can tune them over time to make less use of the runtime. I believe we can see this happening.

More positively, Adobe is benefiting from the demand for rich content across both web and applications, and has just reported decent financial results, showing the company’s resilience.

Finally, everyone is asking what Adobe will do about Microsoft’s WIndows 8 Metro platform for tablets, given that browser plug-ins are not supported. Here is the answer:

… we expect Flash based apps will come to Metro via Adobe AIR, much the way they are on Android, iOS and BlackBerry Tablet OS today

though I hope this will be delivered more quickly than the promised Flash runtime for Windows Phone 7, which is not a subject either Adobe or Microsoft seems willing to talk about.

Update: Adobe has also announced the Flex 4.6 SDK and Flash Builder 4.6, which supports these new capabilities including Captive Runtime and Native Extensions, and has new controls specifically aimed at tablet apps.

Building Windows – when Microsoft shows its hand

I’m in Anaheim, California on the eve of Microsoft’s BUILD conference. I have heard the phrase “wait until BUILD” so many times from Microsoft over the last few months that it has given this conference a special flavour. After Wednesday, the company will have to think of another way to avoid awkward questions like what is happening to Silverlight.

This is the latest chapter in the progression of Windows, server client and mobile. In particular, I will be trying to understand Microsoft’s software development platform. Whatever it looks like, it will be diverse, and include native code, HTML and JavaScript, .NET code including Silverlight, and perhaps some new hybrid. What will be the pros and cons of each approach, how do developers create apps that span desktop, tablet and mobile, and how will the delivery model change in the app store era?

Interesting questions; but the other theme is about how effectively Microsoft will compete versus its competition as the importance of desktop Windows shrinks. Cloud, mobile and tablet are the themes here, and after many mis-steps time is running out.

Not much to add except “watch this space” over the next few days; though I would be interested in any specific comments or questions on Microsoft’s strategy.

PhoneGap comes to Windows Phone

Nitobi has announced PhoneGap for Windows Phone 7, nicely timed just before the Microsoft BUILD conference next week.

PhoneGap is a cross-platform mobile development tool that uses the HTML and JavaScript engine on the phone as its runtime, supplemented by extensions which give access to other device features:

After unpackaging the contents of the www folder, your www/index.html file is loaded into an embedded headless browser control. This is essentially the same paradigm as other platforms, except here it is an IE9 browser and not a webkit variant. IE9 is a much more standards-compliant browser than previous IEs, and implements commonly used html5 features like DOMContentLoaded events, addEventListener interfaces, and CSS3. Be sure to use to get the html5 implementation otherwise the browser may fallback to a compatibility mode, and your code will likely choke and die.

The version for Windows Phone 7, just released in preview, is extended to support features including the camera, accelerometer, contacts, and notifications. There is also support for plugins:

PhoneGap-WP7 maintains the plugability of other platforms via a command pattern, to allow developers to add functionality with minimal fuss, simply define your C# class in the WP7GapClassLib.PhoneGap.Commands namespace and derive your class from BaseCommand.

In general Windows Phone 7 is not well supported by cross-platform toolkits, so PhoneGap support is an interesting development. PhoneGap has a high profile currently, and is being integrated into a diverse range of tools ranging from Adobe Dreamweaver to Embarcadero RadPHP, as well as the standard PhoneGap tools based on Eclipse.
