Silverlight, WPF, HTML 5, Metro and err…Flash…

20 09 2011

There is a lot of talk about these technologies, especially
after the Windows 8 BUILD preview. For many, Silverlight and WPF appear to be
dead, simply because it isn’t supported in the Metro world of Windows 8…This
technically is and isn’t true, depends what you think is in a name…

Windows 8 Metro

Looking for Files from any application in the Metro world, 1 single user experience

WPF and Silverlight

Both of these are essentially built on .NET libraries, which
in the desktop mode are still there, just as they are in Windows 7. However, in
the Metro world, these libraries have made their way into the WinRT library
collection, with this in mind and the fact that Metro runs XAML, you see that,
well the names may have changed, but Silverlight and WPF does run in Metro.

To “Metro” your application you do have to make some
changes, and these are very small indeed, we are talking a few changes to
include libraries and that’s about it. These changes though appear to be mainly
focused on touch enabling your application fully in the Metro world.

So if you wrote WPF applications and or Silverlight apps
that run OOB (out of browser), then things are pretty much business as normal. However,
if you wrote RIAs in Silverlight and had them running in the browser, then you
won’t be too happy. You see IE10 in the Metro world will not support plugins,
and that’s probably all down to touch and touch based libraries. If you want to
run Silverlight in a browser, then you need to be in desktop mode and use IE10…Not
perfect, but makes sense…

We also have to remember what we want to have as our
experience on the machine. You see, Silverlight in browser mode, and even
Flash, does deliver “Applications”, but the user experience can be very
different between apps. In the Metro world, Metro isn’t just about making your
apps run on that part of the OS, but is also about a seamless experience, look
and feel between all applications. It is also about integrating these
applications with the OS and other installed applications. What does that mean?
Well you cant have a Flash or Silverlight app running in Metro that then doesn’t
behave as other apps do, or more importantly how a user expects them too. In
the Metro world we can “Search” inside apps, we can seamlessly share content
and data between apps that never knew anything about each other. If we allow a
Silverlight app from a browser to run, then it won’t support this level of
experience, and more often than not, it won’t look and feel like a “Metro” app.
That consistent look and feel is what users want, expect and Microsoft has to
enforce…

Charms and searching within Apps

All apps should behave the same, deliver that same look and feel and support functions such as "Search" and "Share" in the same way. A single user experience

Apps

Apps are essentially the future for the desktop and the web,
Microsoft understands this, just as well as Apple does. You see the web was
never designed to deliver us “Applications”, rather it was designed and
architected to distribute and deliver content. This is primarily why we have
plug-ins for browsers, as even HTML 5 has limitations on what you can and can’t
do. Throw into the mix the horrible issues that arise with browser
compatibility and you see why Apps are far better for the user and for the OS.

Just as we have with mobile phones (and Apples iPad for
example), we will have an app store, which allows us to purchase (or get for
free) applications, for Windows 8, these will be XAML (WPF / Silverlight apps)
or HTML 5 with Javascript (though I believe and suspect XAML will be the
technology of choice).  In this way, Apps
will behave in similar fashions, so it makes it easy for any user to add more
apps to their machine and use them quickly and efficiently. This isn’t the case
with browser plugins nor with typical “chrome” based applications.

Death of Flash?

Well not really, but I do fear this signals the beginning of
the end for Flash. Essentially if you develop in Flash, I would be jumping ship
fast! I also have a chuckle when I think of apps such as Tweet Deck, which essentially
will have to be “Metroed” or make its users have to move to the desktop. Since
I have seen Tweet@rama in demos on Windows 8, I think Tweet Deck will have to
get itself “Metroed”, if it wants to stay alive…

Flash will be on the desktop side of things only for Windows
8, and that includes AIR. So what does this mean for Flash? Well why would a
user want to “flip” into desktop mode, go to a website or open a Flash based
application and leave the lovely Metro world behind? It isn’t going to happen.
Sure for business applications, complex studios (such as photoshop), users won’t
mind moving back to the desktop, but then it makes sense to be in desktop mode
for these kind of complex applications. But most things in Flash are either to
enrich our web experience or to provide a cross platform simple(ish)
applications – such as Tweet Deck. So in the new world, those apps would be
delivered by XAML in Metro and by HTML 5 in the browser, leaving nothing for Flash
to deliver.

The future…

Well the future of the web is HTML 5, the future of real
RIAs is Apps as too is the future of desktop applications. For complex
applications and legacy applications we will have the classic Desktop mode from
Windows 8, and I think this makes a lot of sense. Essentially Windows 8 is
everything to everybody; no matter what they want, expect and need to run…

WPF and Silverlight developers will simply be named Metro
developers (or something similar), web developers HTML 5 developers and Flash
will slowly disappear from the PC as it has already the iPad and probably Mac
OS…

Why does Apple love HTML 5?

20 03 2011

There is an awful lot of talk and hype regarding HTML 5, with one of its main advocates being Steve Jobs and more importantly, Apple as a company…What so many don’t ask themselves is “why is Apple making a big push for something that essentially provides them no revenue”

 Apple often site HTML 5 as one of its reasons for not supporting Flash and Silverlight, stating they support the web free of plug-in technologies and want to ensure the web stays open source etc etc. Whenever I hear this it is so obvious that there is a different agenda, after all it makes no sense for Microsoft (with Silverlight) or Adobe (with Flash) to charge for these technologies, if they did, no one would use them and no websites would leverage them to deliver rich applications. What I continually find astonishing is the amount of so called journalists and bloggers that believe that Apple want a free, open web. Let’s remind ourselves, Apple exists to make money…

What’s in it for Apple?

Let’s ask ourselves, what’s in HTML 5 for Apple? I mean really in it for them? The answer is, Apps…

Now I may have lost you there, you probably thinking apps have nothing to do with HTML 5 as such, and you would be right. You see, HTML 5 is the future of the web for sure, and it will bring new life to the web with animiations, even video playback to an extent, (though we have this via Flash and Silverlight already, so nothing new to the web, just new to HTML). HTML 5 won’t make the web a “richer place”. You see, HTML 5 will still suffer the same limitations, namely running in a browser, the web architecture and the end user experience (not to mention cross browser compatibility issues, DDA compliance etc etc). This means websites wont be all singing and dancing apps, rather they will remain pretty much website experiences we have at the moment (well with a bit more “jazz” to them). You see, Apple is counting on the web going back to its roots more, and we are seeing this with many more websites looking cleaner, and simpler to meet certain compliancy issues and to make life easier for users (not to mention making life easier for developers when supporting all browsers across all platforms). What Apple doesn’t want is real rich applications to be delivered via HTML 5, well not the type that can compete with desktop based applications, or mobile apps.

Apple doesn’t want HTML 5 to be the wave of the future for application development because it can’t make money from that, rather it wants us all to have to “download” and use specific “apps” for platforms. Think the iPhone App store and you see what I am getting at.

Essentially one of the biggest reasons people opt for the iPhone is not because it’s the best looking phone, it has the so called best screen display (which it doesn’t) nor these days for its revolutionary touch screen and OS, no, it’s because of the App store, and the rich “internet” experiences these apps open the user up to.

Flash and Silverlight are technologies that can deliver “apps” via the internet and over the internet, cross platform, cross browser etc and all from the same code base. This is a real threat to Apple. After all, if I can write a great app using Silverlight and have it deployed with small mods to any form of device, then as a development company I have opened up my markets and saved money. This is a good thing. However, Apple now would have an app that, though rich and great on its platform, is just as good and readily available on other platforms. Which detracts from some of the appeal of its own product.

You see, Silverlght and Flash are real threats to Apples unique “app” store.

Here is an example of why Apps are the future and why Apple wants us all to love HTML 5.

How do you use Facebook on your mobile? Do you use a browser and the HTML version? Probably not because it’s too slow, clunky and the end user experience not that great. You use Facebook via your Facebook app for your mobile, which you downloaded from an App store (for apple, android or market place for windows). Apple take this further with the iPad, providing not just an app for your iPhone, but a slightly different app that works better on the iPad, the iPad being something that apparently is designed for web experiences on the go. Yet it still wants you to download apps, and, that is one of the reasons why Apple don’t want us to use Flash or Silverlight, because these technologies can deliver rich “apps” onto any platform potentially, not just specific to the iOS.

Today I watched an advert for sky news, and there was no mention of the sky news website, only that, for the very best experience, use the sky news iPad app…What does that tell you?

This confirms that Apple see Apps as a way of cornering the web market, especially when over 30% of web consumption was via mobile devices last year in the UK. The future of the web is reverting back to information based sites, with richer websites being delivered in HTML 5 yes, but real applications, and real rich intuitive experiences that work on multiple devices coming from dedicated apps.

Conclusion

Apple doesn’t want to supports Flash or Silverlight, if it did it means they have lost their app store edge. Imagine sky news delivering one solution for all platforms via Silverlight. The advert would have been “get the very best experience with our Sky News App, for iPhone, iPad, Windows Phone, Android and to your desktop”…Immediately, I don’t need to have an iPad to get the very best experience, rather I can choose which device, which OS, all of which detracts from Apple’s marketing and business plans in many may ways.

Apples tactics of using “content” to help us make the decision to purchase their hardware aren’t anything new. Look at how VHS beat off Beta-max? VHS was a lesser solution, but it had more content on it, and more to the point, content that was in high demand. Because of this, it meant users opted for the VHS platform as they then got the films they wanted, which meant Beta-max sales dropped until there was only one, VHS.

So while we all harp on about how great HTML 5 will be, we must remember that the big players (especially Apple) want it to succeed only to destroy Flash and Silverlight, which plays right back into their hands of delivering true rich experiences, only via their platform specific dedicated apps and app stores..And of course, we all do, so we will all be using apps to access the web…

I am a strong believer in the future of the web being Apps, as applications will always be able to potentially deliver far richer end user experiences. What I don’t want to see though is the need access the best experiences based on hardware and what is made available though an “App” store.  We should be able to access these apps directly from web pages, and opt for the mobile version, or the desktop version, or the slate version.

HTML 5 may be a way of lighting up HTML and making it richer, but it potentially could also be the way of forcing us all down the route of App stores and choosing hardware to best access web content. Now to me, that is not the point of HTML 5…





The future of the web? Apps all the way…

11 02 2011

This year will be the first year it is believed, that web access will be carried out on more mobile devices than actually through a PC or laptop. That’s a massive shift in the way we use the web. But don’t think that means we are sticking with browsers and HTML 5 even. What it really means is that more of us are looking towards mobile apps for access…

Take an example, do you from your mobile device use Tesco website for your shopping, or do you use their app. Almost everyone will say the app (if you shop at Tesco via the web that is). So why do we use the app and not the website? Simple, user experience…

Apps User experience

The problem with mobile devices is the screen real estate, they are simply small, even when you use an iPad, the real estate is smaller than a traditional netbook or my 19” wide screen TFT monitor…So seeing everything can be tricky, and it means scrolling around a lot. Secondly is the experience, waiting for pages to load over the web etc etc.

Apps provide a more “desktop” type experience, often loading is done in the background or even core data is stored on the device. So that means performance is greatly improved and we don’t have to pay greater network charges. In addition, apps are designed specifically for the realestate problem, so we get nice smooth experiences which make browsing using a web browser pale in comparison…

What can we learn from this…

What we learn is that, HTML 5 may be the future of websites and even rich internet experiences on the web and to some extent mobile devices, but the future is still on the device itself. Running software via a browser is architecturally inefficient; it’s very restrictive and comes with no end of issues. That’s simply because the web was not designed to deliver applications, rather it was designed to deliver content.

Can we deliver “apps” to the desktop? Yes we can. This is something I am a strong believer in. The web is great for delivering content and communications between the client and a server. If we make the small leap that components of an application are content, then we see that we can deliver desktop apps down to the client via a website, and have them communicate with servers in the cloud over HTTP. This is why I love the Silverlight model, as it’s all there…

Delivering applications this way makes the most of the web architecture and leverages all the benefits of being on the desktop, just as “mobile apps” make the most of being on the device. This is a great way of delivering real applications to business users, either over the web or intranet, running them out of the browser. You have a desktop app, with all the flexibility of a web app. A great solution….

Facebook scenario?

I’m not saying this is where we should all be, but websites such as Facebook would benefit massively from having a desktop app version. Why? Well how many people do you hear actually compliment the Facebook website on its looks, feel and how they use it? I don’t think any, rather I hear constant moaning about its performance, lack of intuitive navigation and, well the list goes on. The only good point is that they can access it over the web. But, how many use Facebook the website on their phone? Hardly any, rather they opt for their devices Facebook app (which delivers a better experience than the website most times). So if you had the choice as an end user, would you  have a rich desktop app for Facebook, rather than having to go to the website? I know I would!

Silverlight and Flash can deliver those capabilities, HTML 5 cannot. I think the future should be HTML 5 for websites, Silverlight and or Flash for desktop “web” apps…





HTML 5, Flash, Silverlight, The Cloud…The future is here?

8 11 2010

I.T. seems to be at one of those cross-roads in terms of how people use software, where they use it, and how and where they choose to store their data.

There has been a lot in the press regarding HTML 5 and I have posted some thoughts on this in the past. There has been equally as much speculation as to the future of technologies such as Flash and Silveright and whether they are now redundant technologies as HTML 5 moves closer. In addition to these, rather large discussions, we are also talking about moving content and software away from traditional servers and PCs, and handing control over to the “Cloud” and “SkyDrives” etc…

So this post is looking at indicators of where we may all end up based on feedback I have received from businesses, the general public, phone professionals and my own thoughts…

HTML 5

This is the easiest one to start with really. HTML 5 will be here, at some point. Many say a lot sooner than I personally believe and many (as there always are) saying this will change everything (which it won’t at all). What HTML 5 will do, is simply to replace the need for browser plug-in to enrich a users web experience to an extent. For example, we will no longer typically use Flash or Silverlight to just stream video, give our website some pretty animations etc etc. Some will argue that’s a good thing, and if you are a purist (in terms of open environments, using only HTML to deliver content) then yes it is. For Video and animations, yes it is a good thing…

However, there are big problems with the whole architecture and the way HTML and the web in general works. The problem here is the web browser. When the web was conceived, the browser was simply an application that displayed some content, it wasn’t to be used as an environment in which processing can occur. But, we are here, and the browser is used to run “script” and to initiate communication between the client and the webserver…HTML sets out standards, but, with everything, with multiple choices (in terms of browesers here) you get different results. No matter what standards are in place, web browsers handle, and will handle the same HTML and even script differently to each other. This is a horrendous state of affairs, meaning that the same website has “allowances” for multiple browsers. This isn’t good…From an end users point of view, “who cares”, but from a development, maintenance and cost point of view, this is not acceptable really. Even if the browsers did handle it all the same (or got very close), testing would still need to be made on each browser platform, and for every time a new browser is released / updated. But this is where we will still be with HTML 5, don’t listen to any marketing hype or to any so called “experts” on this….This is simply the facts….HTML 5 will not change the web for us at all…

Silverlight and Flash

HTML 5 will have a big impact on Flash I believe, after all sites that utilise flash do so to enrich the website. HTML 5 will do this, and unfortunately for Flash, developers will adopt this and leverage it before they look at Flash. So where can Flash go? Well there are still many things Flash can offer that HTML 5 won’t be able to, or at least won’t be able to offer consistently across all browsers. Because of this I see Flash filling small gaps that HTML 5 leaves (the same applies to Silverlight). I do think though Flash will see a massive reduction its use on the web, but will maintain its use for presentations, short movies, and games.

Silverlight is a little different. I have never really seen Silverlight as a pure web technology, and those out there who keep comparing it to Flash or HTML 5 obviously know nothing about Silverlight. Sure Silverlight can give you animation online, deliver RIAs, stream movies etc (all that Flash and HTML 5 can do), but Silverlight has a lot more to offer. The architecture behind Silverlight I feel is spot on. It mixes both the worlds of Desktop and Web seamlessly, effectively delivering desktop applications (with all their power) via the internet for installation, communication and maintenance. This is very different to HTML 5. Because of this, developers will use Silverlight for business applications, for RIAs that need to do more (integrate, carry out complex functions etc) and all without the reliance on the browser or server doing processing jobs. This reduces testing and ensures a single code base (and that’s how it should be). In addition, you get frequent updates, and full support from Microsoft, which again are good things for real developers…

There has been some confusion as of late (mainly in the media and Microsoft haters) as to the value of Silverlight to Microsoft and the fact that it is also used on the new Windows Mobile & platform. Let’s get this clear, Microsoft will concentrate more now on HTML 5 as HTML 5 is a big online technology, and it needs to keep up with others. So this is no surprise. However, Silverlight is and will remain a core development platform for the web, RIAs, Out of browser applications and experiences (which it does now). Sure the Silverlight team will also now work more on its Mobile use and adoption, and that’s because they need too. So all we are talking about is prioritisation of the progression of Silverlight. This is clear from reading up on Silverlight, looking at Microsofts future plans and listening to what is said rather than reading between lines when a press release comes from Microsoft…Silverlight will become increasingly more important to Microsoft in the future, as more developers realise that they can use a single platform to code for the web, the desktop and mobile devices…

Cloud computing, SaaS and SkyDrives

I mention SkyDrives here as that is what Microsoft terms your cloud computing storage space with Windows Live and on your windows mobile 7 phone.

I think in the past couple of weeks, I have had more feedback than ever before on the cloud and its use, from both businesses and the general public.

So let’s look at businesses. Businesses cannot move everything over to the cloud, it’s as simple as that. There are savings to be made via the cloud for business, but it has to ensure that it can move those applications and content to the cloud. That it doesn’t already have a cheaper alternative, that it can trust the cloud providers security measures etc 100% and that there is a way to port to other providers in the future. All in all, business is still wary of this and why shouldn’t they be. I see businesses embracing the cloud and SaaS for smaller elements of their operation, ones that do not require so much compliance and that are not that critical to the organisation. This is not a bad thing, rather it is a good thing, the cloud here allowing IT to provide better solutions to the business at lower costs. I don’t believe the increased popularity of the cloud will translate to vast amounts of an organisations data or services being moved to the cloud. Rather the cloud becoming another IT implementation option.

So what of individuals. Well only last week I posted that individuals may well be the big winners of cloud computing. But even here, individuals are more sceptical of cloud based services. It seems that keeping some photos online, music and videos is fine. But when it comes to more personal documentation, you cannot beat a good hard drive or storage device at home. Because of this, I don’t see the masses adopting cloud computing and sky drives….Google may want us all to use the Cloud for software and storage, but the simple fact is, we like control over everything. If our data and content is only in the cloud, then we feel vulnerable, not just to theft, hackers or work colleagues finding things out etc, but also to cloud providers themselves. Let’s face it; Google has an appalling record on data protection and our privacy.

So what is the right usage for individuals? Well Microsoft though I feel has pitched it correctly. Providing 25Gb of space in a sky drive to windows live users (perhaps a little too small really). This is enough space for most people, sure it could be larger to allow us to synch a lot more content, especially music and videos. But it’s a good start. I also love the fact that my Windows Mobile 7 phone provides options to just take a picture and have it stored in my skydrive and not on the device. But, I still have enough space on the device to cart around with me a certain level of music, pictures etc etc. (No doubt this amount of storage will grow). So it’s a nice blend, one I personally am comfortable with, and one most people I speak too are comfortable with…

Conclusion, if any?

It seems in IT, too many marketing companies, experts etc provide to much hype. Everything is also “brilliant” or “rubbish and a fail”. It’s either 100% the way of the future or 0%…There is never any middle ground, and it is the middle ground which actually is where we are heading, in terms of our web usage, devices, online services and storage…And there is nothing wrong with that at all…





HTML 5 – It’s not the end of internet plug-ins

4 06 2010

I have posted a number of times now about HTML5 and my concerns that people see it as a complete replacement for internet plug-in such as Silverlight and Flash, allowing RIAs to be delivered in pure HTML 5. One of the main people who keep going on about HTML 5 is Steve Jobs (though I think a lot of this is trying to convince the users of iPhones and iPads that Flash has a short life ahead). However, it seems that more and more people are sharing my opinion that HTML 5 will not kill of Flash and Silverlight, and that its adoption is a hell of a long way off in general…A recent report and article from Forrester illustrates this…

HTML 5 traction and buzz….

There is for sure a lot of buzz around HTML 5 in the past couple of months, least not because of Jobs, but also because Google has recently open-sourced its VP8 video codex. To date, abilities and licensing issues surrounding such video converters have been one of the sticking points for beta HTML 5, however this is not the only issue. Though there is a lot of internet buzz, it seems that adoption of HTML 5 is a long long way off, with browsers only supporting small fragments of HTML 5 currently. It seems that for wide spread adoption, as users we will be waiting until 2020 or sometime around then…That’s not exactly close is it…Its again another reason why I am not at all “hyped up” about HTML 5, it’s just so far off….

So while HTML 5 is a long way off, just think how much traction Flash and Silverlight will gain in this period. Silverlight is the new boy on the block, but has already around 60% adoption across all machines. That’s rather impressive, all this while HTML 5 is in beta releases and going through a lot of, development pains and issues shall we say…

There is also the issue of cross browser issues. Just like HTML 4, HTML 5 will suffer at the hands of different browsers. The author of the Forest report (Hammond) stated “Until you get consistent behaviour the question will be why you would use HTML 5 when it actually creates more challenges than it solves from a testing and deployment perspective.” I have to say, this has always been an issue with HTML in general, especially when delivering internet applications, and it is one that won’t go away for HTML 5…Though HTML 5 is supposed to be intended as an enterprise-class product, the reality is that the architecture of HTML 5 with the browser has a number of issues and draw backs, even when talking to web services. Though the aim is for HTML 5 to allow easier building of “applications” the fact is that HTML and that side of the web architecture was never designed with this in mind….

Test once…You are all done…

Ahh, well this is not the case is it with HTML. Unfortunately you will need to perform tests on all the browsers out there, and no doubt, place “HTML fixes, CSS fixes and JavaScript fixes” into your application depending on what browser is running it. This does make life a lot harder for testing and development, oh, and of course ongoing support. However, this problem is just not there for Flash and Silverlight, because their architecture is completely different and in many ways separate from the browser and the web in general, indeed you can run Silverlight out of the browser fine…

Hammonds recent report – titled “Does HTML 5 Herald the end of RIA Plug-Ins? Not Really” – found that application delivery through RIA amongst businesses rose to 34% in 2009, up from 26% in 2008. This illustrates the increase use of RIAs amongst businesses, especially with technologies such as Silverlight develop further, all this while HTML 5 is still in its draft phase…

For traditional website material, you could still use HTML and HTML 5 if you wish, however for complex functions and applications, I would always recommend the use of Silverlight, there are just so many hurdles you negate while being able to use a technology that isn’t restricted by the browser web architecture.

Open aspect of HTML 5

So many people claim they love the idea that HTML 5 is “open”. And there are some good arguments made for this, however I have yet to see one example where these arguments are valid. Especially arguments that users may have to pay for Flash or Silverlight use, that you can become restricted to what browsers you can use, or that you are dependent on them for your support…I don’t see an issue or potential issue with any of these arguments, they are just created so people try to feel more safe with an “open” technology controlled by many rather than a single company…

However, this open aspect of HTML 5 may also work against its progress and adoption, especially as open standards are very slow to develop. HTML 5 has been in development for a decade now, and though early candidate releases are recommended for 2012/13, it is a while yet before we see HTML 5 as the standard version of HTML being used. On top of that, cross browser issues and W3C adoption is even further off…

Architecture…

RIAs require processing on the client, or at least they should do. Users expect “thick client” performance and usability in an RIA and on top of that, access to hardware components, such as storage, web cams, other applications running on the client etc etc. The architecture behind the web and HTML jsut doesn’t allow this. Though HTML 5 will bring us a richer web, with easier video playback, website animations and improved usability (a little like Ajax has done), it will always be behind Silverlight for example, that can take advantage of hardware on the client, keyboard interactivity, integration with other applications and the ability to work in a “disconnected state” from the internet….

My own view on the use of HTML 5 in the future…

It simple, for typical web content, HTML 5 will provide a greater level of interactivity, animation and improved user experience. It will no doubt be used for “simpler” RIAs, however its adoption as a serious RIA for businesses is plain fantasy. RIAs need to deliver more, and therefore organisations will continue to look to plug-ins, especially Silverlight more and more. I also believe that websites available to the general public will also have more aspects delivered in Silverlight, even once HTML 5 has gained traction, simply because Silverlight can deliver a better end user experience without many of the hassles associated with web development and HTML, CSS and JavaScript across multiple browsers…..
