Latest trends in mobile technology, tech startups and coding

2013 key technology retrospective

Here are some of the developments in technology that caught my attention in 2013.

iOS 7

Featured fantastic advances that brought iOS to the forefront of mobile OS market. (Can you tell that I am an iOS developer:)?). The design aesthetic, the ability to easily and reliably (finally!) integrate with iCloud especially for developers, Airdrop to share with data with people around you, iTunes radio, a more advanced Siri, Core Motion advances including M7 and camera advances including face and smile detection.

iPhone 5S and iPad Mini Retina

This phone rocked with its 64bit capable A7 processor and the M7 motion co-processor with fast networking and LTE along with a better camera. The Touch ID was a bold attempt in finally bringing fingerprint based technology to the mass market and it works quite well. With the iPad Mini Retina, Apple did the impossible - pack the same processor and power as an iPad Air with the Retina display into the mini iPad footprint. Need I say more?

M7 Motion Coprocessor

The M7 deserves separate mention because of its step counting features and activity monitoring in the iPhone 5S without burdening the A7 and draining too much battery. No additional devices to purchase for these features. New iPad Air and iPad Mini Retina have the M7 but only Activity monitoring is enabled in them.

If you own an iPhone 5S, you may support the author(me) by checking out these 2 cool new apps designed exclusively for the iPhone 5S utilizing the M7 motion coprocessor. They track your steps indoors and outdoors without GPS, record your walking history and enable you to reach your daily step goals with no other devices to buy other than your iPhone 5S.

10k Steps

Glass from Google and wearable technology

It is undeniable that the Google Glass is a fantastic technology and will be more available to the masses in 2014 and beyond. Sure, there will be privacy concerns etc. but wearable technology is IN! Lets also get more bags with solar panels and jackets with lightning connectors and start using them, really!. I worry a lot about the EM fields that these devices(phones, computers) generate and look forward to innovative devices that provide protection from these fields like the Pong cases for iPhone.


Pebble did it ! They started as a Kickstarter project and they were able to mass produce a full-featured smart watch for a reasonable price. Sure, there are more apps and upgrades desired but nevertheless it is a fresh and innovative product. The last release of the Pebble OS supports iOS7 notifications and more features.

4k Displays

With the new (and powerful) Mac Pro supporting upto 4 4k displays, this is quickly becoming the new standard for advanced graphics displays. 4k tvs from Sony, Samsung and LG were out there and personally, I am waiting for their prices to come down a bit in 2014 and beyond. 8k displays soon? Believe me there is a spec out there.

Full frame DSLR within the reach of the prosumer

With the Canon 6D and Nikon D610 priced as low as in the 1500s (body only), there is hope that this was the year these cameras are putting this technology within the grasp of the consumer. 2014 may usher a sub $1000 full frame DSLR? Maybe:)

Mac Pro

Amazing features like compact design, graphics, 4k display support out of the box. Pricey but worth it if you need the graphics and processing features that this machine uniquely offers in a durable, compact design backed by Apple.

Voice Recognition becomes standard and more useful

Google voice and Siri as well as Xbox One all deserve a mention.

Other notable tech events/happenings in 2013

First lab grown meat burger was "produced" and eaten. 3D printers became more mainstream and cheaper.(esp. when a Makerbot store openend near my apartment). Crypto currencies like BitCoin accompanied with all the advanced mining hardware and volatility were certainly more in the public eye. Smart gadgets including the Nest learning thermostat, Jawbone speakers and Philips app enabled bulbs etc. More devices with built in smarts coming our way in 2014. Sony Playstation PS4 and Microsft Xbox One put gaming on a new level but with limited available games. I played Call of Duty: Ghosts on PS4 and it was quite an experience. On a 4k display (note PS4 does not support 4k yet) it would be out of this world. Maybe in 2016:). Ouya Android based gaming console(another Kickstarter project) broke into a market dominated by Sony, Microsoft and Nintendo. Lastly, crowd funding stood out (again) as a force in 2013 and will continue too in 2014 and beyond.

Happy holidays and a happy new year!

And thank you for your support! See you in 2014!

Essence of the October 22, 2013 Apple event and the unveiling of iPad Air

- iPad Air is out (on Sep 1, 2013 in stores and online). Features - A7 64 bit processor along with the M7 co-processor with faster processing and graphics with an eye towards battery saving, only 1 lb heavy and about 20% thinner.  Looks like a larger version of the mini footprint with its slightly square edges.  No fingerprint touch id Frown in this version. Comes in silver and space gray.  Expanded LTE coverage.  Larger pixels for the back camera.  Faster WiFi with Mimo/dual antennae (lookout Amazon Fire which has had this technology for sometime).

- iPad Mini is out at the end of November.  Powerful, new A7 processor and Retina display are the major things that stand out.  Also, it has all the other features of the iPad Air in a mini footprint.  Basically, packs the same power as the iPad Air in a convenient mini (now with Retina) package.  This model will truly rock! Might finally move to the mini after this release.

- Macbook Pro lineup is upgraded with the latest Intel chips namely Haswell and Crystalwell architectures and Iris as well as Iris Pro graphics.  Slight price reduction as well.

- Mac Pro is coming in December. Mini drum shaped, polished aluminum casing and quite a design I must say.  Pure power and runs cool.  For the professional with multi-core CPUs/GPUs.  More on this in a separate article.

- OS X Mavericks is out today and is FREE.  I was quite happy to hear that. And so are Apple apps - KeyNote, Numbers and Pages (yes) for new purchasers of Apple devices.  Mavericks features Maps, calendar with Geo location awareness, tagging, fantastic power saving features and more.  Available as a free upgrade to even users of Snow Leopard.  But do check the recommended hardware specs from Apple before downloading on the older machines.  I will write a separate blog on the over 200 new features of Mavericks.

Overall, it was quite a satisfying event and Apple did give away a lot of free goodies.  Looking forward to ordering my iPads (one of each please).

Looking forward to all the potential and a much greater audience for 64 bit code.

iPhone 5S - the skinny

Following are some of the top features of the new iPhone5S :-

  • New Gold finish in addition to Silver and "Space Gray".  Gold looks great and is my choice of iPhone.
  • New fingerprint identity sensor built into the home button.  Fantastic technology that enables no more annoying passcodes to remember.  Where do the fingerprints go?  They are saved in a secure place in the CPU(more on this later).  This topic is so vast that I will publish a new article for it in the future.
  • Memory 16GB, 32GB or 64GB.  I am suggesting the 64GB option for developers and hard-core users for the HD movies and 64bit code that carry a larger footprint.
  • Dimensions are pretty much the same as the iPhone 5.
  • New A7 64 bit CPU for running 32 bit and 64 bit applications.  HD Movie editing on an iPhone, any takers? Apps that use floating point arithmetic like 3D and graphics (memory) intense applications will benefit immensely.  Games too (especially from the Open GL-ES 3.0 support)
  • New M7 Motion coprocessor aids in all the motion related activity monitoring (including gyroscope, GPS, accelerometer, compass etc.) unburdening the powerful 64 bit A7 with more meaningful tasks and saving power thereby.
  • Supports all the major 802.11 a/b/g/n for WiFi.  I was hoping for 802.11ac support but I knew that was asking a lot. Maybe next release iPhone 6? Definitely going on my wishlist.
  • Apps:  Lots of new 64 bit apps.  iTunes has a radio option.  Pages, Keynote and Numbers are free now! (for new buyers of iPhones)
  • Display: Same retina display as iPhone 5.
  • Camera: Enhanced with 8 megapixels with 1.5µ pixels.  So much larger pixels thereby resulting in better photos.  Also, aperture of f/2.2 means more light control and again better low light shots as well.  The try-tone flash is a big improvement over the iPhone 5.  I will present some photos soon to compare and contrast.  
  • Front-side Camera features 720p HD and 1.2MP photos with video stabilization.
  • Video features for HD 1920p, 30fps and cool features like slow-motion.

In short, it is a great phone.  64GB Gold is my choice.

iOS 7 thoughts and musings from the Apple WWDC 2013 keynote presentation and demo

My thoughts and opinions about this presentation/demonstration as well as exciting features of iOS 7:-

- Simpler, sleek UI with a redesign of icons.  Very flat, 2D and noticibly absent was the gloss effect in the current version of iOS.  Does that mean app developers have to redo their icons?  I doubt it, IMHO.

- New light fonts are used extensively for that clean, graceful look that Apple is known for.  The light typeface may pose some difficulty in the readability with certain backgrounds but that remains to be seen. The fonts reminded me of a Windows Phone look but still a little different and cooler (of course!)

- COOLEST FEATURE (IMHO) is the feature that achieves depth in parallax which makes the icons almost move (as the background shifts ever so slightly) as the device is moved so as to giving the effect of looking under them. Very, very cool.  Lets hope this feature in the future matures to the UX in general and not remain just a novelty in the top level screens.

- Unlock the phone by swiping in more than one way; a new beautiful, translucent Control Center can be swiped in from the bottom at all times;  some features here a bit Android inspired but welcome nevertheless.  Control center controls WiFi, Bluetooth, Airplane mode as well as music playing and more. Flashlight is included in iOS 7. Ahhhh just when I was thinking of writing my own cool flashlight app:).

- New Home screen "Today" with notification can be swiped from the top. Also, includes weather, reminders, birthdays and appointments.

- Revamped weather app shows dynamic weather animations - I have seen this on Android but still good to have it on iOS.

- iTunes improvements including new iTunes Radio (ad free for customers of iTunes Match I believe).  Look out Pandora and other music streamers:)

- iCloud photo-sharing and iCloud keychain remembers sensitive data like passwords etc.  improvements in photo organization and sharing with others' photo streams.

- Phone, FaceTime, and iMessage blocking from unwanted callers is quite a welcome feature that I am looking forward to using.

- Activation lock to protect against theft was really cool as even after a reset an iCloud authentication needed to use the phone.

- Showed improved Maps. Nice 3D view of Paris at the demo.  More navigation support for use in cars etc.

- Push notifications from iOS apps could be received by the new OS X Mavericks.  Cool option to have in some cases.

- Airdrop for peer to peer proximity sharing is quite useful. Only on Wifi I believe.

- Multitasking features as all apps run in background. Battery implications remain to be seen :).

- App updates in the background automatically.  What a fantastic option this is as I will not be clicking on update all apps each time to get all latest copies of installed apps.

- More advancements and improvements in Siri, including a new male voice and search results from Bing! (No Google here).

- And many many more features...

The SKINNY: During the demo it was mentioned that there were more than 1400 new API calls for developers.  While the UI is redesigned and some features appear to be improvements inspired by what is on Android and Windows Phone, IMHO iOS 7 is quite an amazing leap forward.  Furthermore, I want to check under the hood as there are many new features for developers - especially Xcode 5 Preview and iOS SDK 7(Beta).  Cannot wait to play with these asap. 

Happy dreaming of iOS 7 until the Fall when it is released!

Google Glass the specifications demystified from the hype (Part 1)

I am highlighting some of the cool tech features of this new, cool gizmo. 

Fit and form

As per Google, it has adjustable nosepads and durable frame to fit any face.  Since I have been wearing glasses for over 30 years I think they will have have more options for a custom fit.  Personally I will like to buy the attachment to fit my Dior Homme frames if possible and available.  I did read about this being a possibility but not confirmed yet.


The high resolution display is the equivalent of a 25 inch high definition screen from eight feet away.  Reminds me of the dvd watching personal glasses that projected (privately) on a virtual 60inch screen.  Nothing new here as this technology has existed for at least a decade in the consumers hand.

Front Camera

For Photos, a 5 MP resolution is enough but low compared to the standards of today.  Samsung S4 has a 13MP rear camera.  So not to excited about this feature.

For Videos, a 720p HD but not full HD which is the new norm for all the latest mobile devices.

Networking and Wifi/Bluetooth

Wifi 802.11b/g protocols supported.  No support for 802.11n or newer protocols in this release.  Bluetooth support but I dont know the version. Will post when I do more research here but the definite capability to communicate with an Android based smartphone Android 4.0.3 (Ice Cream Sandwich) or higher indicates Bluetooth 2.0+. More on this later.  With a mobile phone connected, SMS and GPS is enabled.

Memory and Storage

12 GB out of 16GB of usable memory which by itself is not much but since it is synced with Google cloud storage - this becomes a powerful option.  This is one of my favorite features but more memory will be needed for this to be useful.  Being on the road in Asia with no access to the cloud might hinder some of the usability of the device.  Also, networking has to be fast to upload data to the cloud. 

Battery and charging

Google claims one full day of typical use. Not sure what typical use is but I am sure the batteries offer ample use for the day.

Uses a standard micro-USB port for charging with a Glass charger(recommended by Google).  This is a relief as there is not a new lightning like connector adding to the list of non-standard non-generic connectors out there.


Will update asap

Speech Recognition and Audio

Will post my findings

 I have not got my hands on it yet but a lot can be deduced from its published technical specs as shown above.  I will definitely buy this when availble to the public and am ready to play with it as a developer.  New era of games and apps await us with this fantastic device.

 Happy Glass-ing,

Ouya - A cheap, interesting and feature packed gaming console for developers and users

Ouya - the game console

I am excited about this new console so I decided to blog about it.  It started as a kickstarter funded project that was oversubscribed very quickly.  I was not able to catch it in time but I would definitely be interested in getting a new console that is Android based and has a fairly open policy for developers to write software for it.

Key features(Hardware):

- Form factor: Small with cool wireless controllers;  Dimensions: (2.9in x 2.9in x 3.2in)

- CPU : Tegra 3(Quad-core processor)

- RAM: 1 GB RAM , 8 GB on-board flash

- Full HD (1080p) with HDMI connection

- Network: WiFi 802.11bgn

- Other technologies: Bluetooth LE 4.0

- Did I mention a $99.00 price? Wow!  As per Amazon, Ouya is being released to all on June 4, 2013. 

Software and SDK features:

- Java based development environment; Eclipse with ADK is what I would use for it.

- Supports Android Development Kit 4.0 (API 14).

- Ouya Development Kit released under Apache License.

- I read somewhere about using Unity to write 3D games for it as well.

- No fee to develop on Ouya.

- Easy submission and fast approvals so I have heard  and it sounds good. Pros : makes happy developers  Cons: Loss of quality control.

Looking at all the hardware and software features Ouya offers (mentioned above - I am sure there are more) makes me very excited about this platform.  What about non gaming apps?  I will investigate further and blog about it.  Time to download the Ouya Development Kit.

Very excited about this, A bientot!
