DocType HTML5 – Free 1-day conference on html5/css in Pune – Dec 4

DocType HTML5 is a one day conference on HTML5, CSS3 and related technologies. This is a free, technology-focused event aimed at helping folks get started with HTML5 as a rich application platform.

DocType HTML5 will be held in Pune this Saturday, December 4, from 9am to 6pm, at COEP (College of Engineering, Pune).

This is a free event, and anybody can attend. You need to register here

The first edition of DocType HTML5 was in Bangalore on October 9. A full report of that edition is available here. That should give you an idea of what the conference is about. The schedule and list of speakers for the Pune event haven’t yet been finalized, but the talks are likely to be similar. Each edition has a different set of speakers and is customized around the interests of participants. After you register, you will be asked to pick the topics you’re interested in. They will customize the sessions and find subject matter experts based on your choices.

About the Organizers – HasGeek.in

DocType HTML5 is organized by HasGeek, a new initiative focused on creating high quality community-driven technology events.

HasGeek was created by Kiran Jonnalagadda after he realized that technology events “by the community” could be improved significantly if someone else were to take over the job of logistics and of finding sponsorships. That way, the community could focus on the content. This is what HasGeek does. It is a private company that organizes the DocType HTML5 conference in various cities (and will presumably start organizing other tech conferences in the future). The conferences are free for anybody to attend, and HasGeek takes care of the logistics (venue, lunch, tea/coffee, registration) and getting enough sponsorships to pay for all of that.

What I really like about HasGeek is the professional way in which the it appears to be run. Poke around on the HasGeek wiki to understand what I mean. See the detailed updates on the feedback received from previous conferences. Look up the conference router project.

What should you do

If you would like to attend, register here.

Techweekend Pune – Rich Internet Apps (HTML5, Javascript, Flash, Silverlight) – 27 Nov

The desktop is dead. The browser and the mobile have killed it.

For years now, there has been a shift away from traditional desktop apps and native OS GUIs towards browser based interfaces for all applications, whether they’re personal/consumer apps, or enterprise apps.

Now, with the rise of very smart phones like iPhone, tablet devices, 3G internet available everywhere, and the coming of age of rich interactions in HTML with HTML5 and javascript, “ubiquitous computing” has finally arrived. People expect to be able to work on their applications from anywhere – from their desktop PC at work, or their laptop from home, or their iPad or iPhone or Blackberry when on the road. And the easiest way of ensuring that your app is available on all these platforms is to go with a “RIA” platform.

That’s what we’ll discuss this weekend on Saturday, November 27, at MCCIA Hall in ICC Towers on S.B. Road. We will talk about HTML5, and why it will take over the world. We will talk about how Javascript is the one language you cannot afford to not know, whether you’re talking about apps on your laptop or on your mobile phone. We will talk about Phonegap and Titanium, cross-platform platforms that allow you to write once using Javascript/HTML/CSS and run the app on desktops or mobiles alike. We’ll talk about Adobe’s offerings – AIR and Flash, and how they are the “incumbent” rulers of this space, and will not easily lose to HTML5. And we’ll talk about Microsoft’s Silverlight, and how that plans to break into this club.

The talk is free for all, and you must come, if you want to know what the world will be like for the next 3 years. You need to register at http://techweekend4.eventbrite.com. That page also contains the current list of speakers (which is being updated as we get more confirmations).

Yes, you, the people working on desktop frontend GUIs using java or .NET or VB or Qt – you are the ones who definitely need to come. Some might argue that desktop apps are certainly not dead – definitely not in enterprises. That is true, but only in the same sense as mainframes are still not dead in the enterprise, and COBOL is still not dead in the enterprise. But, for the forward-thinking, RIAs are the way to go, even when you are confined to the insides of your enterprise – just the expansion of that term will change to Rich Intranet Apps. That’s all.

Many thanks to Microsoft for sponsoring the venue for Techweekend. Microsoft wants to get more closely involved with the tech community in Pune, and particularly the open source enthusiasts – with the intention of making everybody aware that their cloud technologies (like Azure) actually play well with open source, and that you can deploy your php applications, your drupal/joomla installs on Azure.

Event Report: IndicThreads Conference on Mobile Application Development

(This is an event update about the IndicThreads Conference on Mobile Application Development that was held in Pune last week. We already published one article related to a couple of the the talks at that conference. This article, a more comprehensive update, was posted by Atul Nene on his blog, and is re-published here with permission.)

The good folks at IndicThreadsHarshad Oak and Sangeeta Oak, organized the IndicMobile conference. The venue and arrangements were very good and the set of speakers top notch. The choice of topics was varied enough to be comprehensive and yet very relevant and amenable for deep enough dives. Overall, a great interaction and learning opportunity that I and my colleagues enjoyed. I also enjoyed live tweeting along with SaurabhPuneLiveMukundVishvesh. Here are my notes from the conference. They are longish, but then it was a two day affair, and I have tried to be brief.

Anand Deshpande, Persistent, Keynote Address
As expected, there was deeply thought out articulation from Anand on the future of the software space. Mobile + cloud is ‘it’, he said. Economic sense is driving everything on the cloud and that, combined with the all pervasive mobile technology will rewrite the software world, as we develop and use it today. He referred to the Harvard Business Review C.K. Pralhad and R. A. Mashelkar paper and pondered that more will be made available for less, for the many – elucidiating Gandhian principles. He made a core point about the data being separated from the App.

I like Anand’s ‘cows and milk’ analogy: focus on milk, why care about tending cows ? Applied to software, focus on developing and using software (App), not building the cloud. But – to take the analogy further – what control one has on chemically adulterated milk ? Its very difficult to even identify that. And, what about reliability and security and so on on the cloud ? Or is there a business case for the ‘organic software experience’ ? We as software product developers will have to figure it all out.

Rohit Nayak, Cross-platform mobile development: choices and limitations
Nice coverage of cross platform mobile development tools. I didnt know there was no garbage collector on the iPhone while there was one on the desktop. Titanium can be used for building cross compiled native apps on various platforms. It also has a good reference application that can be used to test all kinds of interfaces of the device you are building for, as well as sample code ready to be used. MoSync and PhoneGap were also covered. All three were demoed. He warned that tools can be out of step with device styles and new devices. He also suggested that a mobile web app could be the route of choice for maximum platform coverage. I noticed mere mention of MeeGo, but after all, its too new as of this writing. [See MeeGo related previous post on this blog.

Romin Irani, Mobile Web Applications using HTML5
Romin went over the new stuff in HTML5 – semantic elements, forms, audio video embedding, location, and so on. He pointed out that ‘native app like’ experience was possibly via use of local storage, graphic functions and media support. Is it possible that webkit advances render native app development obsolete ? After all, lot of commonly used JavaScript functionality were being included in HTML5. He mentioned that HTML5 would reach ‘recommended’ status by 2022! I’m sure, Holy Photons will guide us there through the paradigm shifts of 2012 et al. 🙂 I believed that an HTML app won’t give a native experience on the device but much to my delight, he demoed HTML5 features in a cool looking app with really nice look and feel. An engaging session with great examples of varied browser support.

Hemanth Sharma, Adobe Flash Platform for Mobile Development
Hemanth covered the various Adobe tools. Interestingly, none of the attendees present had developed for the platform so far. He pointed out that while designing for multiple screens, especially small, knowing the screen resolution was not enough and that the physical dimensions, the orientation and pixels-per-inch (PPI) were crucial. Amongst many other things, he mentioned DeviceCentral as a useful tool to test for devices that support flash. While iOS does not support flash, its cool that Adobe has ActionSript3 cross-compilation for iOS – it generates a native iOS application. He demoed real fast development of an app that gets twitter trending topics. His live demo broke by a whisker – must have kicked himself, mentally – he then showed us previously built code. Still cool. I would have loved stats (performance and so on) comparing native apps with similar functionality. All-in-all, a compelling write-once-run-anywhere-on-air story by this Adobe evangelist. Need to seriously evaluate the platform.

Balagopal K S, Deep dive into Application development for Nokia Technology Platforms
Bala had the difficult task of keeping us awake after lunch. He spoke all about the various platforms one can develop for, for Nokia devices, including the Symbian, Maemo and MeeGo. And of course all about Qt. I wasn’t expecting a Nokia representative to pronounce Qt as ‘quetee’. Everyone knows its ‘cute’, pun not intentionally intended 🙂 He revealed that 83% of users downloaded apps rated 4 and 5 (of 5). Shows how crucial it is, to build a high quality app that includes a great user experience. He advised to design for the user, not the technology, and consider the emotional engagement of the user with your app. And some more tidbits and tools and resources. Given that Qt is the development platform of choice on MeeGo, and a lot of Qt development is done in Python, I wonder why C++ is the language of choice for Qt/Meego. Its like going retro, no?

Pradeep Rao and Dilip Sridhar, BlackBerry Development Platform
BlackBerry just released the Torch and that has the BB6 platform. They have tieups with advertisers and an API that developoers can use in their apps. RIM does 60% revenue share with the app developers. BB SuperApps are native apps that are always on and connected, proactive and notification driven, highly contextualised, designed for efficiency in terms of network usage, battery life and so on. The Theme Studio and Theme Builder lets you make themes easily. The Playbook is coming. This platform is one to watch out for. Lately, BlackBerry devices have started delighting more and more number of users, notwithstanding their funny ads, and they have a powerful development platform plus increasing marketshare to entice developers.

Navin Kabra, Understanding the Touch Interface
Have you noticed how, the moment you start discussing something related to design, that hovers closer to art and makes the audience remember their most delightful and very frustrating moments with technology, everyone just tunes up their attention to the level of communion. Holy Photons ! This is exactly what happened in Navin’s session. He declared: “Touch will take over the world”. He made many excellent points, one being that using a mouse is a learned skill while touch comes naturally and that every app developer irrespective of whether he will develop for the mobile platform or not, will need to care about touch, simply because touch based devices will be the most commonly used devices going forward.

Also, a piece of text that is large enough for you to read is not necessarily large enough to touch – you will know this if you browse the web on your touch phone. Touch can be so easy that our spinal cord should be enough to do processing and give our brain some rest – everyone could do with that, I suppose. He showed a very interesting design of a touch keypad that can be used singlehandedly to browse the web because it has most of the frequently used functions on convenience buttons. He also touched upon – pun intended – the problems with touch, user perception of what is good and bad response time, caution of not overdoing it and perhaps most importantly, that developers wanting to design for touch must use a touch only device for a sufficient period of time !

I really liked the mindmap style (including the navigation) for the presentation. Made a mental note to make one this way at the next oppurtunity. Abhinav (an attendee) made an excellent point about designing in such a way that, with all the touch he can get, the user is still able to efficiently ‘blind type’, assuming he also has a physical on-device keyboard at his disposal – touch and type should not go out of sync. Really interactive and great talk on how to design for touch. And some informative follow-on interactions around stylus vs. fingers, resistive and capacitive touches, and handwriting recognition, the Palm (now Access) Graffiti et. al.

I personally feel there is huge potential for handwriting recognition or at least the Graffiti on the mobile platform – too many potential users who know native, local languages are currently ignored and can be empowered to communicate for low costs, in ways that come naturally to them.

Venkata Ratnam V, Introduction to bada platform & Samsung’s multi-platform strategy
Venkata explained Samsungs dual strategy with Bada (means the ocean, and does not have roots in the Hindi ‘baDaa’ i.e. big, as someone said to me) being for the low end devices while the other mobile OSes that they sell devices with, are for the high end devices. Looks like a large set of attendees were Android lovers and didn’t buy the Bada story but Venkata said ‘Dont grudge us our own mobile OS’. Its difficult to argue with that! He also made a wonderful observation: Customer (end users) expectations are very, very high. They want features on the phone that they may not use, but if the device doesn’t have them, they feel its handicapped.

One can develop for Bada with the combination of C++ and Eclipse, plus a web toolkit. There is also a memory leak checker bundled along with the developer toolset. As others, Samsung has a lot of other pieces of the mobile puzzle being put together in their own way. ‘In-App Purchase’ – is this new ubercool feature being bandied about. IIRC, Apple, Nokia, Samsung have it, others will want to catchup. Venkat also made a great point about user psychology – it’s easier to have an app in the store that is installed by the user and which then stays on the device and tends to be used more. This app can then of course use the web as needed. But its very difficult to have the user point his browser to a website from his device. Point to be taken ! Good session by this evangelist: funny slides, cheerful demeanour, solid defence.

Vikram Pendse V, Microsoft Windows Phone 7 Platform
Vikram Pendse’s overview of Win Phone 7 platform, architecture, development tools, demos and quirks was nice. He did a good job of explaining the Microsoft perspective for WP7. MS wants a consistent hardware strategy across vendors: ARMv7 Cortex/Scorpion or better, and decent combination of GPU, memory, display, capacitive touch, and sensors (GPS, accelerometer, proximity). There will be 3 buttons – Start, Search, Back. For developers, there is .NET compact framework and Silverlight. The OS supports ‘prioritised’ (not concurrent) multitasking of Apps. Libraries include cloud integration for Azure. He demoed apps to showcase various capabilities – graphics, app bar, music, UI navigation. As also a profiler. And pretty pictures of devices: Dell Venu Pro, HTC HD7, HTC Surround, LG Quantum, Samsung Focus. And some game screens.

MS story looks sketchy at best, and we tweeters had fun ! So WP7 won’t copy and paste. Surprised ? You shouldn’t. Remember C&P has moved to the iPhone last year?! There is no migration plan for apps written for WinCE 5/6. You gotta rewrite, in a different language! Romin noted: what Android calls “Intents” …. Microsoft calls “Launchers and Choosers”. Saurabh noted that WP7 is a fancy looking toy, but only for end user, developers will have to wait for more support and perfection. I agree – the UI looks really cool for end usage. Vishwesh: MS was dead after WM6.5 and now, with limited support for everything on WP7, they are … a zombie? The marketplace seems to be the weakest (non-existent yet ?) link. Too many restrictions imposed by the OS. The audience was wondering if all MS wanted to sell was under-USD-30 devices! Good fun 🙂

Rohit Ghatol, Getting Started With Android Application Development
Rohit began well. He gave some background on the platform, showed a list of devices in the market and asked: Do I really have to sell Android? The audience didn’t think so anyway. He also was the first person to do a live device demo in the conference. He covered stuff efficiently – Building Blocks of Android (Activity, Service, Content Provider, Broadcast Receiver, Notification Mgr, Alarm Mgr), the Dalvik VM, the DEXs and the APKs. He was swift through building an App and covered lot of details in short time. Froyo (API v8) brings the much needed enterprise security features to Android, while GingerBread and Honeycomb come later to focus on tablet features.Developer.Android.Com is a very well documented site and a great resource to learn at. We also discussed some could-be-better stuff – one is tablet support, another is that Android market does not provide flexible payment options, sometimes you can make more money by making the app free and include Google ads! Rohit had a nice conversational style, good use cases, employed simple stepping through the development process on a well done deck.

UnConference
I liked this flexible approach. The audience identified pertinent topics for an open discussion and we had scintillating set of discussions on 4 topics. Difficult to capture all learning and speakers, but I hope I’ve got the gist.

Abhinav, Mobile Virtualization: Can we run multiple logical phones on one physical phone ? There are multiple applications. 3 years ago, you ran your PC at 1GHz, today you run your handset at that speed. In terms of device capability, virtualization seems plausible. Clouds will only separate the data from the device. What if you want to use your corporate mobile and your personal mobile on the same physical handset, for convenience ?

Saurabh, OpenGL: Useful for graphics and game development. Optimal use of hardware resources. Common library across platforms, however, support varies across platform. Simple games like ‘Bejeweled’ are being used more over serious games that need a console, simply because they are more available, like while waiting for the doctors appointment.

Vishwesh, Apps for the Indian Market: Firstly, is there an Indian Market? Consumers have to use apps developed for the western market. Where’s the Indian Content ? Pricing is a challenge. Prices are converted from USD to Rupees, needs to be thought differently. Rural market, huge but not addressed. Difficult to monetise. We don’t even SMS in local language yet. Amar Chitra Katha – available on one provider when it needs to be ubiquitious. Cash-On-Delivery is the preferred payment option for Indian Consumers, and this needs to be used for selling Apps. Microfinance has the potential to be in top-ten-app charts, but there aren’t any apps! And then there are too many platforms! Mobile Apps should connect to the physical, real world of the End User. It’s only then that they will be used

Dr.Lavania, Tele-Health: What is the best way to reach 24×7 touch and feel health services to rural areas, given that mobility is the only ubiquitious technology in villages! Apps that degrade from smart to dumb phones are needed. What low cost solution can we have for villages that are ‘over the horizon’ of connectivity?

Anand Hariharan, Performance in Android: Tips and Techniques
“Good Design is the practice of Subtraction” – Mark Anderson from the Good Design blog. Anand suggested we keep performance in mind right when you are desiging the App. Design, Measure, Identify, Improve : thats the mantra he gave us for performance extraction on mobile platforms. Speed, responsiveness, robustness, good behaviour (wrt battery usage and working well with other Apps) – all these done together make an App with good performance. Intensive CPU/battery usage, UI freeze (jankiness), long periods of percieved inactivity, actions that are not cancellable – any of these make an App bad, and it runs the risk of uninstallation from the users device! Apps should be designed to work well over varying net speeds. Recommended practices and style guides of respective platforms are important also for performance aspects. Like on the iPhone, its a good idea to show the image of your App, during startup, while the App loads – this improves user perception on response time. Android has a useful guide called Designing for Performance

Anand had specific advice – dos, donts – for Android apps in particular and Java apps in general. Do lookup his presentation on the conference site, it has a lot of depth and coverage – a handy reference for all developers, I’d say. Fluent talk, and I thought, Holy Photons – worth emulating!

Romin Irani, Power Your Mobile Applications On The Cloud
Romin has written a book on Google App Engine and you can download it for free. GAE is feature rich and free, has enough resources for trying out apps. He did a quick run through basics, and did a live demo – write, test, deploy! Simple, klaar, not cloudy at all. 🙂 You can code in Python or Java. Cloud in general and GAE in particular has great potential for mobile space. You could have the same cloud app serve multiple phone apps or even multiple kinds of clients (thick, thin, remote, local, and so on …). Romin mentioned a handy resource for information on about 15,000+ devices ! Checkout WURFL.

All presentations uploaded to the conference page as the talks got over. Pleasant green behaviour on part of organizers – free saplings were on offer for those who care. See the Press Report in DNA. An intense and thoroughly enjoyable conference with a lot of take-aways for me. Hope you have enjoyed reading about it.

HTML5

HTML5 is the next generation of HTML, to reduce the need for proprietary plug-in based Rich Internet Application (RIA) development technologies such as Adobe Flash, Silverlight, JavaFx, etc. The new version will have capabilities of HTML v4.0 plus additional features like DOM management, offline storage database, document editing, drag-drop, etc. This talk will be focused on salient features of HTML5 and how it will influence the next generation RIA development process.

This lecture is useful for all IT professionals and students especially for those, who are seeking to have deep penetration in web and internet related activities in years to come. HTML 5 is probably going to be tomorrow’s mainstream platform for web development – so this lecture is surely going to be an eye opener!

Event report: Mozilla for you Business

(Last weekend, Pune played host to Arun Ranganathan, Technology Evangelist for the Mozilla Foundation, Seth Bindernagel, Director of Localization, and Axel Hecht, who co-ordinates localization from a technical perspective, and Ragavan Srinivasan, from Mozilla Labs. We had a meeting of the Mozilla Folks and the Pune Open Coffee Club. POCC member Gurminder Singh, posted this “event report” on the Pune Startups mailing list. It is reproduced here with permission.)

The whole session proved to be very interesting. Here is short summary about session on 21st/ Feb 2010 at SICSR Pune.

It Started with Arun’s presentation which covered

Open web platform

Open web platform does not mean open source, it means the standards on which web is based should be open. for e.g PHP is open standard and used by facebook to build million dollar business, Google supports and extensively uses open standards. Organizations should involve in defining and shaping open standards while keep in view the way web is evloving.

Using this open web platform million dollar businesses can be built.

The HTML5 standard has many revolutionary features to change the how people interact with web. One of them is Video

Future of Video on Web

Currently there is no standard format of video on web. We can see avi, mov, mp4, flv etc floating all over. People mistakenly assume flash to be standard because of its widespread use. Flash is a proprietary format from Adobe and lacks the open standard definition which makes it hard for Open standard browsers like Firefox to support it. Therefore HTML5 is coming up with new open format for video “Ogg Theora”. Recently  after a lot of community pressure YouTube announced support for Ogg theora format.

In HTML5 using elements like canvas, video and SVG a video can be treated as data and manipulated on runtime. for eg user can put a video inside a video on the fly. It can be used to make ajax calls on video and running it without any third party software.

Firefox capturing device orientation

With new hardware capabilities like accelerometer very common in devices, firefox has come up with new api to capture device orientation events. This capability can be used for better user experience detecting the motion.

Fonts for web

There was small discussion about a company name typekit.com . Typekit provides user with all the fancy fonts which till today were shaped in some image editing software and pasted as image on website.

GeoLocation

Firefox 3.6 is having support for geolocation api. Geolocation identifies the users location and points it on google maps. Under the hood it uses google gears service.

Web3GL

Future firefox versions (maybe 3.8 , 3.9) will have support for 3D graphics. This is based on web3gl component which interacts with OpenGL to render graphics on screen.

The Mozilla-based Business Idea competition

At the end of session Seth, Arun, Ragavan and Axel organized a small contest where in audience was divided in 10 teams of 3. Each team was given 5 minutes to come up with business idea and present it to audience. Presentation time was 1 min and after questioning about business model etc a winner was decided.

Out of the ten business ideas, these 4 were in finals:

  • Typekit.com for indian languages – typekit.in
  • e-learning classrooms for physically impaired – using video in video capabilities of HTML5
  • Making a video using Mashup – e.g Google maps,text to speech audio
  • Using Geolocation api from firefox – giving user local search results like restaurants

The winner was: e-learning classrooms for physically impaired.

It was great experience to interact with team. We are hungry for more such sessions. Thanks for coming and thanks for reading this through 🙂
