Creating a Web Application for the Google Chrome Web Store

January 3, 2011 onlyconnect 1 Comment

I noticed an old post here getting a lot of hits: My first Google Chrome Web Application. Unfortunately it was based on an early version of Chrome’s app format. Here is an update.

My web application in this example is this blog. I created a manifest in Notepad:

Next, using my artistic skills, I made an icon of the required size: 128×128. I used .png format.

Then I put the manifest and the icon into a folder called itwriting-app. I tested it by using Chrome’s Tools – Extensions – Load unpacked extension. It worked fine.

Next I compressed the folder to a zip file. I just right-clicked in Windows and chose Send to – Compressed (zipped) folder.

Then I logged into the Developer Dashboard at the Chrome Web Store (I had to pay $5.00) and uploaded the app:

Next, I had to complete some metadata. I chose a couple of categories, uploaded the icon as the image for the app, and uploaded a screenshot of a sample article. Clicked Publish Changes and it was done.

If you click Install, you get an icon in the Chrome Apps list, which appears when you open a new tab.

Of course it is just a link to a web site. Why is this interesting?

A few reasons. One is that it is easy to get started, which promotes usage.

Next, you can charge for your app. Once the user has paid, you use the Licensing API to check whether the user has paid, or is a trial user, or has not paid. This also depends on the user’s Google ID, promoting Google’s identity system as well as its payment system. Users get single sign-on if they are already logged into Google. Developers do not have to worry about storing passwords, which can be an embarrassment.

Web Apps are also interesting if you request additional permissions. There are three at the moment: geolocation, notifications, and unlimited storage. These give additional capabilities to your app. You can also enable autoupdating.

Finally, Google wants us to accept that web applications are apps too, blurring the boundaries between desktop, mobile device, and web.

What you read in 2010: top posts on ITWriting.com

December 29, 2010 onlyconnect

With three days to go, traffic on ITWriting.com in 2010 is more than 50% up over that of 2009 with over 1 million unique visitors for the first time. Thank you for your attention in another crazy year in technology.

So what did you read? It is intriguing to look at the stats for the whole year, which are different in character from stats for a week or month. The reason is that over a short period, it is the news of the day that is most read – posts like The Java Crisis and what it means for developers. Over the year though, it is the in-depth technical posts like How to backup Small Business Server 2008 on Hyper-V that draw more readers, along with those posts that are a hit with people searching Google for help with an immediate problem like Cannot open the Outlook window – what sort of error message is that?

The most-read post in 2010 though is in neither category. In July I made a quick post noting that the Amazon Kindle now comes with a web browser based on WebKit and a free worldwide internet connection. Mainly thanks to some helpful comments from users it has become a place where people come for information on that niche subject.

On the programming side, posts about Microsoft’s changing developer story are high on the list:

Lessons from Evernote’s flight from .NET

Microsoft wrestles with HTML5 vs Silverlight futures

Microsoft’s Silverlight dream is over

Another post which is there in the top twenty is this one about Adobe Flash and web services:

SOA, REST and Flash/Flex – why Flash does not PUT

along with this 2009 post on the pros and cons of parallel programming:

Parallel Programming: five reasons for caution. Reflections from Intel’s Parallel Studio briefing

This lightweight post also gets a lot of hits:

Apple iPad vs Windows Tablet vs Google Chrome OS

It is out of date now and I should do a more considered update. Still, it touches on a big theme: the success of the Apple iPad. When you take that alongside the interest in Android tablets, perhaps we can say that 2010 was the year of the tablet. I first thought the tablet concept might take off back in 2003/2004 when I got my first Acer tablet. I was wrong about the timing and wrong about the operating system; but the reasons why tablets are a good idea still apply.

Watching these trends is a lot of fun and I look forward to more surprises in 2011.

First impressions of Google TV – get an Apple iPad instead?

December 17, 2010 onlyconnect 1 Comment

I received a Google TV as an attendee at the Adobe MAX conference earlier this year; to be exact, a Logitech Revue. It is not yet available or customised for the UK, but with its universal power supply and standard HDMI connections it works OK, with some caveats.

The main snag with my evaluation is that I use a TV with built-in Freeview (over-the-air digital TV) and do not use a set top box. This is bad for Google TV, since it wants to sit between your set top box and your TV, with an HDMI in for the set top box and an HDMI out to your screen. Features like picture-in-picture, TV search, and the ability to choose a TV channel from within Google TV, depend on this. Without a set-top box you can only use Google TV for the web and apps.

I found myself comparing Google TV to Windows Media Center, which I have used extensively both directly attached to a TV, and over the network via Xbox 360. Windows Media Center gets round the set top box problem by having its own TV card. I actually like Windows Media Center a lot, though we had occasional glitches. If you have a PC connected directly, of course this also gives you the web on your TV. Sony’s PlayStation 3 also has a web browser with Adobe Flash support, as does Nintendo Wii though it is more basic.

What you get with Google TV is a small set top box – in my case it slipped unobtrusively onto a shelf below the TV, a wireless keyboard, an HDMI connector, and an IR blaster. Installation is straightforward and the box recognised my TV to the extent that it can turn it on and off via the keyboard. The IR blaster lets you position an infra-red transmitter optimally for any IR devices you want to control from Google TV – typically your set-top box.

I connected to the network through wi-fi initially, but for some reason this was glitchy and would lose the connection for no apparent reason. I plugged in an ethernet cable and all was well. This problem may be unique to my set-up, or something that gets a firmware fix, so no big deal.

There is a usability issue with the keyboard. This has a trackpad which operates a mouse pointer, under which are cursor keys and an OK button. You would think that the OK button represents a mouse click, but it does not. The mouse click button is at top left on the keyboard. Once I discovered this, the web browser (Chrome, of course) worked better. You do need the OK button for navigating the Google TV menus.

I also dislike having a keyboard floating around in the living room, though it can be useful especially for things like Gmail, Twitter or web forums on your TV. Another option is to control it from a mobile app on an Android smartphone.

The good news is that Google TV is excellent for playing web video on your TV. YouTube has a special “leanback” mode, optimised for viewing from a distance that works reasonably well, though amateur videos that look tolerable in a small frame in a web browser look terrible played full-screen in the living room. BBC iPlayer works well in on-demand mode; the download player would not install. Overall it was a bit better than the PS3, which is also pretty good for web video, but probably not by enough to justify the cost if you already have a PS3.

The bad news is that the rest of the Web on Google TV is disappointing. Fonts are blurry, and the resolution necessary to make a web page viewable from 12 feet back is often annoying. Flash works well, but Java seems to be absent.

Google also needs to put more thought into personalisation. The box encouraged me to set up a Google account, which will be necessary to purchase apps, giving me access to Gmail and so on; and I also set up the Twitter app. But typically the living room is a shared space: do you want, for example, a babysitter to have access to your Gmail and Twitter accounts? It needs some sort of profile management and log-in.

In general, the web experience you get by bringing your own laptop, netbook or iPad into the room is better than Google TV in most ways apart from web video. An iPad is similar in size to the Google TV keyboard.

Media on Google TV has potential, but is currently limited by the apps on offer. Logitech Media Player is supplied and is a DLNA client, so if you are lucky you will be able to play audio and video from something like a NAS (network attached storage) drive on your network. Codec support is limited.

In a sane, standardised world you would be able to stream music from Apple iTunes or a Squeezebox server to Google TV but we are not there yet.

One key feature of Google TV is for purchasing streamed videos from Netflix, Amazon VOD (Video on Demand) or Dish Network. I did not try this; they do not work yet in the UK. Reports are reasonably positive; but I do not think this is a big selling point since similar services are available by many other routes.

Google TV is not in itself a DVR (Digital Video Recorder) but can control one.

All about the apps

Not too good so far then; but at some point you will be able to purchase apps from the Android marketplace – which is why attendees at the Adobe conference were given boxes. Nobody really knows what sort of impact apps for TV could have, and it seems to me that as a means of running apps – especially games – on a TV this unobtrusive device is promising.

Note that some TVs will come with Google TV built-in, solving the set top box issue, and if Google can make this a popular option it would have significant impact.

It is too early then to write it off; but it is a shame that Google has not learned the lesson of Apple, which is not to release a product until it is really ready.

Update: for the user’s perspective there is a mammoth thread on avsforum; I liked this post.

Database.com extends the salesforce.com platform

December 8, 2010 onlyconnect 4 Comments

At Dreamforce today Salesforce.com announced its latest platform venture: Database.com. Salesforce.com is built on an Oracle database with various custom optimizations; and database.com now exposes this as a generic cloud database which can be accessed from a variety of languages – Java, .NET, Ruby and PHP – and accessed from applications running on almost any platform: VMForce, Smartphones, Amazon EC2, Google App Engine, Microsoft Azure, Microsoft Excel, Adobe Flash/Flex and others. One way to use it would via JPA (Java Persistence API) in an VMForce Java application.

The Database.com console is a web application that has a console giving access to your databases and showing useful statistics and system information.

You can also create new databases, specifying the schema and relationships.

The details presented in the keynote today were sketchy – we saw applications that honestly could have been built just as easily with MySQL – but there is more information in the FAQ. The Database.com API is through SOAP or REST web services, not SQL. Third parties can create drivers so you can you use it with SQL APIs such as ODBC or JDBC. There is row level security, and built-in full text search.

According to the FAQ, Database.com “includes a native trigger and stored procedure language”.

Pricing starts from free – for up to 100,000 records, 50,000 transactions and 3 users per month. After than it is $10.00 per month per additional 100,000 records, $10.00 per month per additional 150,000 transactions, and $10.00 per user if you need the built-in authentication and security system – which as you would expect is based on the native force.com identity system.

As far as I can tell one of the goals of Database.com – and also the forthcoming chatter.com free public collaboration service – is to draw users towards the force.com platform.

Roger Jennings has analysed the pricing and reckons that Database.com is much more expensive than Microsoft’s SQL Azure – for 500 users and a 50GB database $15,000 per month for Database.com vs a little over $500 for the same thing on SQL Azure, though the two are difficult to compare directly and he has had to make a number of assumptions. Responding to a question at the press and analyst Q&A today, Benioff seemed to accept that the pricing is relatively high, but justified in his view by the range of services on offer. Of course the pricing could change if it proves uncompetitive.

Unlike SQL Azure, Database.com starts from free, which is a great attraction for developers interested in giving it a try. Trying out Azure is risky because if you leave a service running inadvertently you may run up a big bill.

In practice SQL Azure is likely to be more attractive than Database.com for its core market, existing Microsoft-platform developers. Microsoft experimented with a web services API for SQL Server Data Services in Azure, but ended up offering full SQL, enabling developers to continue working in familiar ways.

Equally, Force.com developers will like Database.com and its integration with the force.com platform.

Some of what Database.com can do is already available through force.com and I am not sure how the pricing looks for organizations that are already big salesforce.com users; I hope to find out more soon.

What is interesting here is the way salesforce.com is making its platform more generic. There will be more force.com announcements tomorrow and I expect to to see further efforts to broaden the platform then.

Update – I had a chat with Database.com General Manager Igor Tsyganskiy. He says Microsoft’s SQL Azure is the closest competitor to Database.com but argues that because Salesforce.com is extending its platform in an organic way it will do a better job than Microsoft which has built a cloud platform from scratch. We did not address the pricing comparison directly, but Tsyganskiy says that existing Force.com customers always have the option to “talk to their Account Executive” so there could be flexibility.

Since Database.com is in one sense the same as Force.com, the API is similar. The underlying query language is SOQL – the Salesforce Object Query Language which is based on SQL SELECT though with limitations. The language for stored procedures and triggers is Apex. SQL drivers from Progress Software are intended to address the demand for SQL access.

I mentioned that Microsoft came under pressure to replace its web services API for SQL Server Data Services with full SQL – might Database.com face similar pressure? We’ll see, said Tsyganskiy. The case is not entirely parallel. SQL Server is a cloud implementation of an existing SQL database with which developers are familiar. Database.com on the other hand abstracts the underlying data store – although Salesforce.com is an Oracle customer, Tsyganskiy said that the platform stores data in a variety of ways so should not be thought of as a wrapper for an Oracle database server.

Although Database.com is designed to be used from anywhere, I’d guess that Java running on VMForce with JPA, and following today’s announcement Heroku apps also hosted by Salesforce.com, will be the most common scenarios for complex applications.

Google App Engine and why vendor honesty pays

December 6, 2010 onlyconnect 1 Comment

I’ve just attended a Cloudstock session on Google App Engine and new Google platform technologies – an introductory talk by Google’s Christian Schalk.

App Engine has been a subject of considerable debate recently, thanks to a blog post by Carlos Ble called Goodbye App Engine:

Choosing GAE as the platform four our project is a mistake which cost I estimate in about 15000€. Considering it’s been my money, it is a "bit" painful.

Ble’s points is that App Engine has many limitations. Since Google tends not to highlight these in its marketing, Ble discovered them as he went, causing frustrations and costly workarounds. In addition, it has not proved reliable:

Once you overcome all the limitations with your complex code, you are supposed to gain scalabilty for millions of users. After all, you are hosted by Google. This is the last big lie.

Since the last update they did in september 2010, we starting facing random 500 error codes that some days got the site down 60% of the time.

Ble has now partially retracted his post.

I am rewriting this post is because Patrick Chanezon (from Google), has added a kind and respectful comment to this post. Given the huge amount of traffic this post has generated (never expected nor wanted) I don’t want to damage the GAE project which can be a great platform in the future.

He is still not exactly positive, and adds:

I also don’t want to try Azure. The more experience I gain, the less I trust platforms/frameworks which code I can’t see.

Ble’s post is honest, but many of the issues are avoidable and arguably his main error was not to research the platform more thoroughly before than diving in. He blames the platform for issues that in some cases are implementation mistakes.

Still, here at Cloudstock I was interested to see if Schalk was going to mention any of these limitations or respond to Ble’s widely-read post. The answer is no – I got the impression that anything you can do in Java or Python, you can do on App Engine, with unlimited scalability thrown in.

My view is that it pays vendors to explain the “why not” as well as the “why” of using their platform. Otherwise there is a risk of disillusionment, and disillusioned customers are hard to win back.

Microsoft lets go of IronPython and IronRuby

October 22, 2010 onlyconnect 2 Comments

Visual Studio corporate VP Jason Zander has announced that IronPython and IronRuby, .NET implementations of popular dynamic languages, are to be handed over to the open source community. This includes add-ons that enable development in Visual Studio, IronPython Tools and IronRuby Tools. Of the two, IronPython is a more mature and usable project.

Why? Here’s a few reflections. For what it must cost Microsoft to maintain these projects, versus the goodwill it earns in the open source world, I would have thought they represent good value and I am surprised to see them abandoned.

On the other hand, it is easy to see that they are not commercial propositions. I’d guess that they were more valuable a few years back, before C# acquired dynamic features, and when dynamic languages were strongly in vogue and Microsoft was keen not to allow .NET to fall behind. To some extent dynamic languages are still in vogue, but we are now well past what is “the peak of inflated expectations” in the Gartner Hype Cycle, and few are likely to abandon .NET because it does not have an official Python or Ruby.

The other reason they are not commercial propositions is that Microsoft has under-invested in them. I recall Martin Fowler at ThoughtWorks telling me that JRuby, an implementation of Ruby for the Java Virtual Machine, is important to their work; it lets them work in a highly productive language, while giving clients the reassurance of running on a trusted and mature platform. JRuby performs very well, but IronRuby is a long way behind. Perhaps if Microsoft had really got behind them, one or both of these language could be equally significant in the .NET world.

The fact that F# rather than IronRuby or IronPython turned up as a fully supported language in Visual Studio 2010 is also significant. After talking to F# leader Don Syme – see the interview here – I understood how F# was important to some of Microsoft’s key customers in the financial world; and I’m guessing that neither Python nor Ruby had that kind of case made for them within the company.

Although it is a shame that Microsoft is withdrawing official support, the clarity of Zander’s statement is better than leaving the projects in limbo. The folk appointed as project leaders are also very capable – Mono guru Miguel de Icaza is on both teams and a great motivator, though it seems unlikely he will have much time to devote to them given his other commitments – and this may actually be good rather than bad news for the projects themselves.

Jim Hugunin, creator of both Jython (Python for Java) and IronPython, is leaving Microsoft for Google, and his farewell is worth a read. He says C# has evolved into a nicer language than Java, but notes:

I like to have a healthy relationship with Open Source code and communities, and I believe that the future lies in the cloud and the web. These things are all possible to do at Microsoft and IronPython is a testament to that. However, making that happen at Microsoft always felt like trying to fit a square peg into a round hole – which can be done but only at major cost to both the peg and the hole.

Which mobile platforms will fail?

October 15, 2010 onlyconnect 5 Comments

Gartner’s Nick Jones addressed this question in a blog post yesterday. He refers to the “rule of three” which conjectures that no more than three large vendors can succeed in a mature market. If this applies in mobile, then we will see no more than three survivors, after failures and consolidation, from the following group plus any I’ve missed. I have shown platforms that have common ownership and are already slated to be replaced in strikeout format.

Apple iOS
Google Android
Samsung Bada
~~Maemo~~ MeeGo
~~RIM BlackBerry OS~~ BlackBerry Tablet OS (QNX)
HP/Palm WebOS
Symbian
~~Windows Mobile~~ Windows Phone 7 and successors

Jones says that success requires differentiation, critical mass, and a large handset manufacturer. I am not sure that the last two are really distinct. It is easy to fall into the tautology trap: to be successful a platform needs to be successful. Quite so; but what we are after is the magic ingredient(s) that make it so.

Drawing up a list like this is hard, since some operating systems are more distinct than others. Android, Bada, MeeGo and WebOS are all Linux-based; iOS is also a Unix-like OS. Windows Mobile and Windows Phone 7 are both based on Windows CE.

While it seems obvious that not all the above will prosper, I am not sure that the rule of three applies. I agree that it is unlikely that mobile app vendors will want to support and build 8 or more versions of each app in order to cover the whole market; but this problem does not apply to web apps, and cross-platform frameworks and runtimes can solve the problem to some extent – things like Adobe AIR for mobile, PhoneGap and Appcelerator. Further, there will probably always be mobile devices on which few if any apps are installed, where the user will not care about the OS or application store.

Still, pick your winners. Gartner is betting on iOS and Android, predicting decline for RIM and Symbian, and projecting a small 3.9% share for Microsoft by 2014.

I am sure there will be surprises. The question of mobile OS market share should not be seen in isolation, but as part of a bigger picture in which cloud+device dominates computing. Microsoft has an opportunity here, because in theory it can offer smooth migration to existing Microsoft-platform businesses, taking advantage of their investment – or lock-in – to Active Directory, Exchange, Office and .NET. In the cloud that makes Microsoft BPOS and Azure attractive, while a mobile device with great support for Exchange and SharePoint, for example, is attractive to businesses that already use these platforms.

The cloud will be a big influence at the consumer end too. There is talk of a Facebook phone which could disrupt the market; but I wonder if we will see the existing Facebook and Microsoft partnership strengthen once people realise that Windows Phone 7 has, from what I have seen, the best Facebook integration out there.

So there are two reasons why Gartner may have under-rated Microsoft’s prospects. Equally, you can argue that Microsoft is too late into this market, with Android perfectly positioned to occupy the same position with respect to Apple that worked so well for Microsoft on the desktop.

It is all too early to call. The best advice is to build in the cloud and plan for change when it comes to devices.

Steve Ballmer ducks questions at the London School of Economics

October 5, 2010 onlyconnect

This morning Microsoft CEO Steve Ballmer spoke at the London School of Economics on the subject of Seizing the opportunity of the Cloud: the next wave of business growth. Well, that was supposed to be the topic; but as it happened the focus was vague – maybe that is fitting given the subject. Ballmer acknowledged that nobody was sure how to define the cloud and did not want to waste time attempting to do so, “cloud blah blah blah”, he said.

It was a session of two halves. Part one was a talk with some generalisations about the value of the cloud, the benefits of shared resources, and that the cloud needs rather than replaces intelligent client devices. “That the cloud needs smart devices was controversial but is now 100% obvious,” he said. He then took the opportunity to show a video about Xbox Kinect, the controller-free innovation for Microsoft’s games console, despite its rather loose connection with the subject of the talk.

Ballmer also experienced a Windows moment as he clicked and clicked on the Windows Media Player button to start the video; fortunately for all of us it started on the third or so attempt.

Just when we were expecting some weighty concluding remarks, Ballmer abruptly finished and asked for questions. These were conducted in an unusual manner, with several questions from the audience being taken together, supposedly to save time. I do not recommend this format unless the goal is to leave many of the questions unanswered, which is what happened.

Some of the questions were excellent. How will Microsoft compete against Apple iOS and Google Android? Since it loses money in cloud computing, how will it retain its revenues as Windows declines? What are the implications of Stuxnet, a Windows worm that appears to be in use as a weapon?

Ballmer does such a poor job with such questions, when he does engage with them, that I honestly do not think he is the right person to answer them in front of the public and the press. He is inclined to retreat into saying, well, we could have done better but we are working hard to compete. He actually undersells the Microsoft story. On Stuxnet, he gave a convoluted answer that left me wondering whether he was up-to-date on what it actually is. The revenue question he did not answer at all.

There were a few matters to which he gave more considered responses. One was about patents. “We’re better off with today’s patent system than with no patent system”, he said, before acknowledging that patent law as it stands is ill-equipped to cope with the IT or pharmaceutical industries, which hardly existed when the laws were formed.

Another was about software piracy in China. Piracy is rampant there, said Ballmer, twenty times worse than it is the UK. “Enforcement of the law in China needs to be stepped up,” he said, though without giving any indication of how this goal might be achieved.

He spoke in passing about Windows Phone 7, telling us that it is a great device, and added that we will see slates with Windows on the market before Christmas. He said that he is happy with Microsoft’s Azure cloud offering in relation to the Enterprise, especially the way it includes both private and public cloud offerings, but admits that its consumer cloud is weaker.

Considering the widespread perception that Microsoft is in decline – its stock was recently downgraded to neutral by Goldman Sachs – this event struck me as a missed opportunity to present cogent reasons why Microsoft’s prospects are stronger than they appear, or to clarify the company’s strategy from cloud to device, in front of some of the UK’s most influential technical press.

I must add though that a couple of students I spoke to afterwards were more impressed, and saw his ducking of questions as diplomatic. Perhaps those of us who have followed the company’s activities for many years are harder to please.

Update: Charles Arthur has some more extensive quotes from the session in his report here.

Google’s web app vision: use our store

October 4, 2010 onlyconnect 3 Comments

I’m at the Future of Web Applications conference in London, a crazy mixture of tips for web start-ups and general discussion about application development in a web context. The first session was from Google’s Michael Mahemoff who enthused about HTML5 and open web standards, while refusing to be pinned down on what HTML5 is, which standards are in and which may in the end be out.

Microsoft is here showing off IE9; but one of my reflections is that while the HTML5 support in IE9 is impressive in itself, there are going to be important parts of what, say, Google considers to be part of HTML5 that will not be in IE9, and given the pace of Microsoft’s browser development, probably will not turn up for some time. In other words, the pressure to switch to Chrome, Firefox or some other browser will likely continue.

I digress. Mahemoff identified four key features of web apps – by which he means something different than just an application on the web. These are:

Local storage – encompassing local storage API and also local SQL, though the latter is not yet well advanced
Application cache – Cache Manifest in HTML 5 that lets your app run offline
Local installation – interesting as this is something which is not yet widely used, but clearly part of Google’s vision for Chrome, and also in IE9 to some extent.
Payments

The last of these is interesting, and I sensed Mahemoff showing some discomfort as he steered his way between open web standards on the one hand, and Google-specific features on the other. He presented the forthcoming Chrome Web Store as the solution for taking payments for your web app, whether one-time or subscription.

I asked how this would work with regard to the payment provider – could you freely use PayPal, direct debits or other systems? He said that you could do if you wanted, but he anticipated that most users would use the system built into Chrome Web Store which I presume is Google Checkout. After all, he said, users will already be logged in, and this will offer the smoothest payment experience for them.

The side effect is that if Chrome Web Store takes off, Google gets to make a ton of money from being the web’s banker.

Outside in the exhibition area Vodafone is promoting its 360 app store, with payments going through the mobile operator, ie in this case Vodafone. Vodafone’s apps are for mobile not for web, but it is relevant because it is trying to draw users away from Google’s Android Marketplace and onto its own store. PayPal is here too, showing its developer API.

The app store and payment provider wars will be interesting to watch.
