Appcelerator Titanium gets Mobile Web SDK, cloud services

Appcelerator’s Titanium cross-platform development framework has moved up a gear with the announcement of two new features:

  • A set of cloud services, based on those acquired with Cocoafish in February this year. These are now known as Appcelerator Cloud Services (ACS).
  • Support for mobile web applications as well as native

These features are integrated into the Titanium development environment, an Eclipse-based IDE which has evolved from Aptana, a JavaScript tool acquired in early 2011. Start a new project, and ACS support is included by default.

The cloud services are hosted on Amazon and comprise the following:

  • Push Notifications
  • User management
  • Photo manipulation and storage
  • Places (rich location storage)
  • Social integration
  • File Storage
  • Check-ins
  • Status updates
  • Chats
  • Friend connections
  • Ratings and Reviews
  • Discussion forums
  • Event planning
  • Messaging
  • Key-Value data storage

“We have a portfolio of additional services rolling out over the next several quarters,” said Jo Ann Buckner, VP of Product Management. There are code examples here. A limited usage of the services is available free, after which it is pay as you go. It is a REST API that you can use from any platform; use of Titanium is not essential.

The other big feature is the Mobile Web SDK. Why is Appcelerator doing this given that it has been pushing native code apps as the way forward for mobile deployment?

“Two reasons,” says Buckner. “The debate has been going on for a long time, is it native, or web? Our position is that it native and mobile web are complementary. We have customers building native apps with Titanium that also want to have a mobile web presence, even for iOS and Android. Some customers will just interact with a mobile web site and never download the application.

“The second is reach beyond iOS and Android.”

Does that mean Appcelerator will not support other platforms such as Blackberry or Windows Phone with its native approach? “This is not a replacement for those efforts. We are investing in support for additional platforms,” says Buckner.

There are differences of course between what you can do in a native app, and what you can do in a web app, and these differences vary according to the target browser. Titanium allows you to write platform-specific code in order to workaround these problems, or to vary the user interface to suit the device. The illustration below shows the new Titanium IDE with an app which targets both Android and the Mobile Web, and you can see the folders on the left which separate common code and platform-specific code (click the image to enlarge).

Titanium installs its own web server for testing. Here is an example running in the Android emulator, served from Titanium.

When should you do a native app and when a mobile web app? “You’re going to build more than one application,” says Mike King, Appcelerator’s Principal Mobile Strategist. “If you are doing an augmented reality application the native interaction is going to require that to be a native application. You can do a forms-based application as well, and mobile web is going to be a better fit for that. Different use cases require different architectures.”

But why do your mobile web apps in Titanium, when you could use pure HTML 5 tools instead? “It’s about one platform for all of your development requirements, as opposed to one for native and one for HTML 5,” says King.

Titanium is certainly evolving with impressive speed. The latest 2.0.1 IDE is a rich tool, and pop-up help guides you concerning supported platforms for each keyword.

Another strong point is the way you can easily write conditional code for tablet form-factors.

The comparison with Adobe PhoneGap is interesting. PhoneGap takes a different approach, supporting native apps but by means of the embedded browser in each device, rather than by building a native user interface. Titanium’s new mobile web support is different in that it runs as a web app in the browser, not as a native app with an embedded browser.

Microsoft open sources further ASP.NET Frameworks, publishes code with Git

Microsoft has released two further ASP.NET frameworks as open source, joining ASP.NET MVC which was already open source. These are published on CodePlex, Microsoft’s open source repository site, using the newly added Git support. You can find the code here.

The two additional frameworks are ASP.NET Web API and ASP.NET Web Pages. Just to recap, ASP.NET supports several frameworks:

ASP.NET Web Forms: the original framework shipped with .NET 1.0 and greatly enhanced since then. Excellent for quickly assembling a dynamic web site but somewhat heavyweight with its ViewState field and complex page lifecycle. Designed in pre-Ajax days.

ASP.NET MVC: A more elegant framework with separation of content from code, amenable to test-driven development, based on controllers and routing.

ASP.NET Web Pages formerly known as Razor: An alternative view engine designed to work with ASP.NET MVC. Uses .cshtml or .vbhtml extension in place of .aspx. A declarative language with codewords like @foreach and @if – though Microsoft’s Scott Guthrie says it is not a language but rather a template markup syntax.

ASP.NET Web API: formerly known as WCF Web API is a framework for building REST services. A key framework if you have a cloud + mobile target in mind. Now gets installed with ASP.NET MVC.

So why is ASP.NET Web Forms not open source? According to Microsoft’s Scott Hanselman:

The components that are being open sourced at this time are all components that are shipped independently of the core .NET framework, which means no OS components take dependencies on them. Web Forms is a part of System.Web.dll which parts of the Windows Server platform take a dependency on. Because of this dependency this code can’t easily be replaced with newer versions expect when updates to the .NET framework or the OS ships.

though it is not clear why this prevents the code being published.

Hanselman adds that Microsoft is not only publishing the code, but also taking contributions:

Today we continue to push forward and now ASP.NET MVC, Web API, Web Pages will take contributions from the community.

Why is Microsoft doing this? Within Microsoft, there have always seemed to be open source advocates like Hanselman, and others who pull back. One answer is that the open source folk are winning more arguments now.

Another take is that this is the outcome of industry-wide changes. Microsoft’s platform is less dominant than it was; it still reigns on the desktop, but Macs, tablets and smartphones are eroding its position on the client, and on the web Netcraft’s figures show steady decline since June 2010:

image

Most of the competition is open source and it is possible that this is a factor behind the latest moves. Microsoft is not open sourcing its IIS web server yet, though Hanselman does make the point that ASP.NET MVC runs well on Mono, the open source implementation of the .NET Framework, which is often used with Apache.

Microsoft’s platform nearly invisible at QCon London 2012

3 Comments

QCon London ended yesterday. It was the biggest London QCon yet, with around 1200 developers and a certain amount of room chaos, but still a friendly atmosphere and a great opportunity to catch up with developers, vendors, and industry trends.

Microsoft was near-invisible at QCon. There was a sparsely attended Azure session, mainly I would guess because QCon attendees do not see that Azure has any relevance to them. What does it offer that they cannot get from Amazon EC2, Google App Engine, Joyent or another niche provider, or from their own private clouds?

Mark Rendle at the Azure session did state that Node.js runs better on Windows (and Azure) than on Linux. However he did not have performance figure to hand. A quick search throws up these figures from Node.js inventor Ryan Dahl: 

  v 0.6.0 (Linux) v 0.6.0 (Windows)
http_simple.js /bytes/1024 6263 r/s 5823 r/s
io.js read 26.63 mB/s 26.51 mB/s
io.js write 17.40 mB/s 33.58 mB/s
startup.js 49.6 ms 52.04 ms

These figures are more “nothing to choose between them” than evidence for better performance, but since 0.6.0 was the first Windows release it is possible that it has swung in its favour since. It is a decent showing for sure, but there are other more important factors when choosing a cloud platform: cost, resiliency, services available and so on. Amazon is charging ahead; why choose Azure?

My sense is that developers presume that Azure is mainly relevant to Microsoft platform businesses hosting Microsoft platform applications; and I suspect that a detailed analysis would bear out that presumption despite the encouraging figures above. That said, Azure seems to me a solid though somewhat expensive offering and one that the company has undersold.

I have focused on Azure because QCon tends to be more about the server than the client (though there was  a good deal of mobile this year), and at enterprise scale. It beats me why Microsoft was not exhibiting there, as the attendees are an influential lot and exactly the target audience, if the company wants to move beyond its home crowd.

I heard little talk of Windows 8 and little talk of Windows Phone 7,  though Nokia sponsored some of the catering and ran a hospitality suite which unfortunately I was not able to attend.

Nor did I get to Tomas Petricek’s talk on asynchronous programming in F#, though functional programming was hot at QCon last year and I would guess he drew a bigger audience than Azure managed.

Microsoft is coming from behind in cloud -  Infrastructure as a Service and/or Platform as a Service – as well as in mobile.

I should add the company is, from what I hear, doing better with its Software as a Service cloud, Office 365; and of course I realise that there are plenty of Microsoft-platform folk who attend other events such as the company’s own BUILD, Tech Ed and so on.

Update:

This is the basis for the claim that node.js runs better on Windows:

IOCP supports Sockets, Pipes, and Regular Files.
That is, Windows has true async kernel file I/O.
(In Unix we have to fake it with a userspace thread pool.)

from Dahl’s presentation on the Node roadmap at NodeConf May 2011.

Google’s Eric Schmidt looks forward to an Android in every pocket

Google’s Executive Chairman Eric Schmidt addressed the Mobile World Congress in Barcelona in confident mood, boasting of the strong growth in Android adoption and saying that the world would need to increase its population in order to sustain current rates of growth.

image

His keynote was in three parts. He kicked off with a plug for Chrome for Android, handing over to another Googler to show off its unlimited tabs and predictive background downloading which gives you near-instant page rendering if you pick the top hit after a Google search.

Next, he gave a somewhat political address appealing for light regulation of the Internet, on the grounds that any change to the current setup was likely to make it worse – “regulators regulate, that is what they do”. He also expressed his hope that fast internet access would be better extended to the world beyond the wealthy elite nations, noting the role of connectivity in the Arab Spring and in making public the actions of brutal dictators.

What has all this to do with Google’s business? Mainly, I suppose, that more connections means more Google searches which means more advertising income; Schmidt acknowledged that this forms the great majority of the company’s revenue, in the high nineties percentage-wise.

The third part of Schmidt’s session was the most interesting, when he took questions. He was asked for his thoughts on companies (I am sure Amazon was in the questioner’s mind) which take Android and remove all Google’s services. It is open source, he said, and that is entirely permissible; his hope is that customers will demand Google services and the Android market.

There was a revealing moment when an Iranian in the audience challenged Schmidt over his appeal for a free Internet. Chrome for Android was not available in Iran, he said, because Google, “your company”, is blocking it.

Schmidt immediately communicated with his legal team, who turned out to be sitting in the front row. Then he confirmed the block and said it was a requirement of US law, because of sanctions against Iran. “I’m with you”, he said, but Google has to comply with the law.

Another point of note was the number of references Schmidt made to privacy issues. He said that we will see increasing personalization of search and better targeted advertising, such that users will not mind it. You will be able to opt out, but according to Schmidt you will not want to. He added that personal data collection and use will continue to advance as far as society deems it ethical, a fascinating turn of phrase and one that bears further examination.

What was not mentioned? Apple, Microsoft, patents, the impact of the Motorola Mobility acquisition (he did say that that this last is not yet complete and that currently the company is managed independently).

It was an impressive keynote overall, given from a position of strength, at an event which is dominated in many respects by Android devices.

A quiet revolution in UK government IT: open source ousting big-vendor lock-in

The most striking and surprising presentation at the Monki Gras developer event in London earlier this week was from two quietly spoken men from the UK government’s Cabinet Office. James Stewart and Matt Wall work on the Government Data Service (GDS), and what they are doing is revolutionary.

What is the GDS? “It’s a new branch of the cabinet office which exists to deliver public services, public sector information in-house, rather than the traditional out-sourcing model,” they explained, though it turned out to be rather more than that.

Wall described his experience of talking to government workers about their IT needs.

A common thing you see from very small to very large is someone in government who wants to get something done, who has a business problem or a user need that they want to serve, surrounded by a complex array of integrators, vendors, contractors, suppliers, and all of that, kind-of locked into that, their ability to manoeuvre or deliver services [is limited].

he explained. The only solution is to reform the way software is procured. They described their boss Mike Bracken’s goal:

We want to move from government procuring systems to government commissioning them, whether we build them ourselves, or just that we know what it is we’re asking for. We need that knowledge.

This is also about breaking the hold of the large vendors and finding ways to work on a smaller scale.

If you want to buy something in government, traditionally, some software or some system, the amount of momentum that you have to get up, the amount of people you can easily engage with, they tend to be from companies that are absolutely vast and they tend to take projects that are absolutely vast, the whole mechanism of working is stultifying for everyone involved. It is not just us, a small group of developers sitting in an office able to write some stuff, because that’s not scalable, you can’t do that for everyone. It’s finding small to medium sized companies, partners, out there in the market and finding ways to engage them … why should five very large companies get all the work?

Mike Bracken and the Cabinet Office minister Frances Maude are currently on the West Coast of the USA, they said.

They were invited to meet the usual suspects, Oracle, the major systems integrators. They cancelled it. They’re visiting Joyent, they’re visiting 10Gen, they’re visiting Twilio [applause]. It’s a wholesale change. We’re looking at how great web services are built.

There is also a commitment to open source. “All of the code that we’re producing is open source and out on the Internet,” they said.

What tools do they use?

Most of the core apps are in Ruby, with a mixture of Sinatra and Rails, and some Scala. We’re using a mixture of MySQL and Mongo for the database,

they told us.

The GDS is currently only about 30 people, 10 of whom are developers. How much impact can such a small team have?

We’ve just started and we’re very small. We’re already having a significant impact in some quite large and some quite small projects. The incoming demand that we face across central government and local government is absolutely astronomical, and one of the things that’s important to resolve over the coming years is how to manage that demand and provide services, abilities and communities for people . . . we never want to parachute into somewhere, rewrite all the systems and then go off somewhere else., that’s not sustainable.

Can this small group really change government IT so profoundly? That is an open question, and perhaps in the long term they will fail. There is no doubting though that this particular team is doing inspiring work. This blog post from GDS yesterday describes how open source participation was used to fix a government web site; it may seem a small thing, but as a new and different approach it is significant.

For more information see Mike Bracken’s post This is why we are here, and take a look at the team’s early work on GOV.UK, which is in beta.

How to brew better software: The Monki Gras in London

I attended The Monki Gras in London yesterday, a distinctive developer event arranged by the analyst firm RedMonk.

This was not only a developer event, with the likes of Andre Charland and Dave Johnson from the PhoneGap team at Adobe, Mike Milinkovich the executive director of the Eclipse Foundation, and Jason Hoffman with Bryan Cantrill from cloud services (and Node.js sponsors) Joyent. It was also a serious beer event, complete with a range of craft beers, a beer tasting competition with nine brews to try, and a talk plus a free book from  beer expert Melissa Cole. An unusual blend of flavours.

image

In charge of the proceedings was RedMonk co-founder and all round impressario James Governor. I am a big fan of RedMonk and its developer-focused approach; it has been a fresh and heady brew in the dry world of IT analysts.

image

The Monki Gras did seem like an attempt by a regular IT conference sufferer to fix problems often encountered. The Wi-Fi worked, the food was fresh, unusual and delicious, the coffee was superb; though brewing good coffee takes time so the queues were long. Not everything scales. Fortunately this was a small event, and a rare treat for the couple of hundred or so who attended.

That said, there were frustrations. The sessions were short, which in general is a good thing, but left me wanting more depth and more details in some cases; we did not learn much about PhoneGap other than a brief overview, for example.

Nevertheless there was serious content. Redmonk’s Stephen O’Grady made the point succinctly: IT decision makers are ignorant about what developers actually use and what they want to use, which is one reason why there is so much dysfunction in this industry. Part of the answer is to pay more attention, and several sessions covered different aspects of analytics: Matt LeMay from bitly on what users click on the Web; Matt Biddulph (ex BBC, Dopplr, Nokia) gave a mind-stretching talk on social network analysis which, contrary to what some think, was not invented by Facebook but predates the Internet; and O’Grady shared some insights from developer analytics at RedMonk.

I had not noticed before that github now gets nearly double the number of commits than does Google Code. That is partly because developers like git, but may also say something about Google’s loss of kudos in the open source developer community.

Kohsuke Kawaguchi, lead for Jenkins Continuous Integration and an architect at CloudBees, spoke on building a developer community. His context was how Jenkins attracted developers, but his main point has almost limitless application:  “Make everything easy, relentlessly.”

Something I see frequently is how big companies (the bigger the worse) place obstacles in front of developers or users who have an interest in their products or services. Examples are enforced registration, multiple clicks through several complex pages to get to the download you want, complex installs, and confusing information. It all adds friction. If the target is sufficiently compelling, like apps on Apple’s app store, developers will get there anyway; but it all adds friction, and if you are not Apple that can be fatal.

The Joyent guys did not speak about Node.js, sadly, but rather on the distinction between a VP of engineering and a Chief Technology Officer. Sounds dry and abstruse? I thought so too, but the delivery was so energetic that they were soon forgiven. Hoffman and Cantrill moved on to talk about management antipatterns in the software industry, prompting many wry nods of recognition from the audience. “It is very hard for middle management to add value,” said Cantrill.

Milinkovich made the point that the most valued open source projects generally make their way to a software foundation; PhoneGap to Apache is a recent example. He then gave the talk he really wanted to give, noting that as new software stacks emerge they have a tendency to re-implement CORBA, a middleware specification from the Nineties that tackled problems including remote objects, language independence, and transactions across the Internet. CORBA is remembered for drowning in complexity, but Milinkovich’s point is that the creators of exciting new stacks like Node.js should at least research and learn from past experience.

Milinkovich also found time to proclaim that “Flash is dead, Silverlight is dead, browser plugins are dead.” Perhaps premature; but I did not hear many dissenting voices.

I tweeted the conference extensively yesterday (losing at least one follower but gaining several more). Look out also for a couple of follow-up posts on topics of particular importance.

Appcelerator CEO on EMEA expansion, Titanium vs PhoneGap, and how WebKit drives HTML5 standards

I spoke to Appcelerator CEO Jeff Haynie yesterday, just before today’s announcement of the opening of an EMEA headquarters in Reading. It has only 4 or 5 staff at the moment, mostly sales and marketing, but will expand into professional services and training.

Appcelerator’s product is a cross-platform (though see below) development platform for both desktop and mobile applications. The mobile aspect makes this a hot market to be in, and the company says it has annual growth of several hundred percent. “We’re not profitable yet, but we’ve got about 1300 customers now,” Haynie told me. “ On the developer numbers side, we’ve got about 235,000 mobile developers and about 35,000 apps that have been built.”

Jeff Haynie, Appcelerator

In November 2011, Red Hat invested in Appcelerator and announced a partnership based on using Titanium with OpenShift, Red Hat’s cloud platform.

Another cross-platform mobile toolkit is PhoneGap, which has received lots of attention following the acquisition of Nitobi, the company which built PhoneGap, by Adobe, and also the donation of PhoneGap to the Apache Foundation. I asked Haynie to explain how Titanium’s approach differs from that of PhoneGap.

Technically what we do and what PhoneGap does is a lot different. PhoneGap is about how do you take HTML and wrap it into a web browser and put it into a native container and expose some of the basic APIs. Titanium is really about how you expose JavaScript for an API for native capabilities, and have you build a real native application or an HTML5 application. We offer both a true native application – I mean the UI is native and you get full access to all the API as if you had written it native, but you are writing it in JavaScript. We have also got now an HTML5 product where that same codebase can be deployed into an HTML5 web-driven interface. We think that is wildly different technically and delivers a much better application.

Haynie agrees that cross-platform tools can compromise performance and design, and even resists placing Titanium in the cross-platform category:

Titanium is a real native UI. When you’re in an iPhone TableView it’s actually a real native TableView, not an HTML5 table that happens to look like a TableView. You get the best of both worlds. You get a JavaScript-driven, web-driven API, but when you actually create the app you get a real app. Then we have an open extensible API so it’s really easy if you want to expose additional capabilities or bring in third-party libraries, very similar to what you do in Java with JNI [Java Native Invocation].

The category has got a bit of a bad rap. We wouldn’t really describe ourselves as cross-platform. We’re really an API that allows you target multiple different devices. It’s not a write-once run anywhere, it’s really API driven.

80% of our core APIs are meant to be portable. Filesystems, threads, things like that. Even some of the UI layer, basic views and buttons and things like that. But then you have a Titanium iOS namespace [for example] which allows you to access all the iOS-specific APIs, that aren’t portable.

I asked Haynie for his perspective on the mobile platform wars. Apple and Android dominate, but what about the others?

RIM and Microsoft are fighting for third place. I would go long on Microsoft. Look at Xbox, look at the impact of long-term endeavours, they have the sustainability and the investment power to play the long game, especially in the enterprise. We’ll see Microsoft make significant strides in Windows 8 and beyond.

Even within Android, there are going to be a lot of different types of Android that will be both complementary and competitive with Google. They will continue to take the lion’s share of the market. Apple will be a smaller but highly profitable and vertically integrated ecosystem. In my opinion Microsoft is a bit of bridge between both. They’re more open than Apple, and more vertically integrated than Google, with tighter standardisation and stacks.

I wouldn’t quite count RIM out. They still have a decent market share, especially in certain parts of the world and certain types of application. But they’ve got a long way to go with their new platform.

So will Titanium support Windows 8 “Metro” apps, running on the new WinRT runtime?

Yes, we don’t have a date or anything to announce, but yes.

I was also interested in his thoughts on Adobe, particularly as there is some flow of employees from Adobe to Appcelerator. Is he seeing migration of developers from Flex, Flash and AIR to Titanium?

Adobe has had a tremendously successful product in Flash, the web wouldn’t be the web today if it wasn’t for Flash, but the advent of HTML5 is encroaching on that. How do they move to the next big thing, I don’t know if they have a next big thing? And they’re dealing in an ecosystem that’s not necessarily level ground. That’s churning lots of dissenting and different opinions inside Adobe, is what we’re hearing.

We’re seeing a large degree of people that are Flash, ActionScript oriented that are migrating. We’ve hired a number of people from Adobe. Quite a lot of people in our QA group actually came out of the Adobe AIR group. Adobe is a fantastic company, the question is what’s their future and what’s their plan?

FInally, we discussed web standards. With a product that depends on web technology, does Appcelerator get involved in the HTML5 standards process? The question prompted an intriguing response with regard to WebKit, the open source browser engine.

We’re heavily involved in the Eclipse foundation, but not in the W3C today. I spent about 3 and half years on the W3C in my last company, so I’m familiar with the process and the people. The W3C process is largely driven – and I know the PhoneGap people have tried to get involved – by the WHAT working group and the HTML5 working group, which ultimately are driven by the browser manufacturers … it’s a largely vendor-oriented, fragmented space right now, that’s the challenge. We still haven’t managed to get a royalty-free, IPR-free codec for video.

I’d also say that one of the biggest factors pushing HTML5 is less the standardisation itself and more WebKit. WebKit has become the de facto [standard], which has really been driven by Apple and Google and against Microsoft. That’s driving HTML5 forward as much as the working group itself.

Top languages on Github: JavaScript reigns, Ruby and Python next

I cloned a github repository today, and while browsing the site noticed the language stats:

image

Git was originally developed for the Linux kernel and is mainly for the open source community. I was interested to see JavaScript, the language of HTML 5, riding so high. PHP, C and C++ are lower than I would have guessed, Ruby and Python higher.

Here are some figures for the venerable Sourceforge:

Java (7,163) 19%
C++ (6,449) 17%
C (4,752) 13%
PHP (3,521) 10%
Python (2,694) 7%
C# (2,481) 7%
JavaScript (2,011) 5%
Perl (1,138) 3%
Shell (757) 2%
Visual Basic NET (688) 2%
Delphi/Kylix (581) 2%

This comes with a health warning. I have taken the figures from the what you get if you browse the directory and drop down Programming Languages; but the total is only about 37,000, whereas Sourceforge hosts around 324,000 projects. I am not sure what accounts for the discrepancy; it could be that language is not specified for the other projects, or they are dormant, or some other reason. But I hope the proportions indicate something of value.

Github is madly trendy, and Sourceforge ancient, so this tells us something about how open source activity has shifted towards JavaScript, Ruby and Python, and away from Java, C/C++ and C#.

Of course the overall picture of programming language usage is quite different. For example, you can get some kind of clue about commercial activity from a job board like indeed.com, which currently has 77,457 US vacancies for Java, 22,413 for JavaScript, and only 5030 for Ruby.

Nevertheless, interesting to see what languages developers on Github are choosing to work with, and perhaps an indicator of what may be most in demand on the job boards a few years from now.

Finally, looking at these figures I cannot help thinking how short-sighted Microsoft was in abandoning IronPython and IronRuby back in 2010.

Trying out nide – a cloud IDE for Node.js

3 Comments

I was intrigued by reports of nide, a web-based IDE for Node.js. It was one of the entries in the Node.js Knockout challenge last summer.

So how do you install it? One line on Linux; but I did not want to put it on my web server and I re-purposed my spare Linux machine last year after one of my other servers broke.

I decided to run up a Debian install on a Hyper-V server that has a little spare capacity.

image

I then followed the setups here for setting up Node.js and npm (Node Package Manager). I also installed nginx which I have been meaning to try for a while. Linux on Hyper-V works fine, though you have to use a “Legacy” network adapter which compromises performance a bit, unless you are willing to tackle installing Microsoft’s Hyper-V integration components for Linux, which do not support Debian though it is said to work. I do not need a GUI and the legacy network adapter is OK for this.

Everything works OK, though I found that nide does not work in Internet Explorer 9. I used Google Chrome, which makes sense I guess since the same JavaScript engine is used by Node.js.

Nide is a simple affair which is essentially a file manager. Projects are displayed in a tree view, and you select a file to view or edit it. The icons at the bottom left of the screen let you create and delete files and folders.

image

The smartest feature is version management. Files are saved automatically and you can easily compare versions and revert if necessary. The “Go backward in time” button shows that auto-saves are quite frequent.

image

There is also a GUI for npm built-in. Pretty good for a competition entry, though I had a few problems.

If you are interested in web-based IDEs, another interesting one is Orion, an Eclipse project.  Executive Director Mike Milinkovich says Orion will ship a 1.0 release later this year.

Asus Transformer Prime update: Google video rental or unlocked bootloader, you choose

Asus has responded to demands for an unlocked bootloader for its its latest Transformer Prime tablet.

It turns out that DRM is the culprit – at least, that is what Asus says on its Facebook page:

Regarding the bootloader, the reason we chose to lock it is due to content providers’ requirement for DRM client devices to be as secure as possible. ASUS supports Google DRM in order to provide users with a high quality video rental experience. Also, based on our experience, users who choose to root their devices risk breaking the system completely. However, we know there is demand in the modding community to have an unlocked bootloader. Therefore, ASUS is developing an unlock tool for that community. Please do note that if you choose to unlock your device, the ASUS warranty will be void, and Google video rental will also be unavailable because the device will be no longer protected by security mechanism.

My guess is that most modders will cheerfully unlock their bootloaders and ditch the DRM. That said, I am not clear why this should void the warranty unless it is software related.
