Here's What To Do To Build A Successful Mobile App

Learnings from Mobile Growth Bangalore Meetup

Here's What To Do To Build A Successful Mobile App

If you're a beginner to the world of mobile apps, you may be looking for someone to guide you. Developing an app and getting it out on the app store is only the start of a long journey. Many questions will hound you from the start. Why are so few users downloading my app? Why do many users stop using the app within a few days? Why are users not making purchases via the app? Why are users not using the app as often as expected?

Obviously, all these questions cannot be investigated at the same time. Where exactly should you focus your efforts and budget? How should the issues be prioritized? Is it a matter for developers, digital marketeers, product managers or customer support staff? Wouldn't it be nice if there's a community of mobile developers to share and exchange best practices? That's exactly what Mobile Growth provides.

When Machines Begin To Talk

An opinion

When Machines Begin To Talk

If there's one thing that's unique about being human, we can't deny that it's speech. Sure, animals have a way of communicating but that's not in any way as refined as we humans do. The key lies in the way we are able modulate sound waves with the rolls and wags of our tongue. Perhaps, it's for this reason we have phrases such as "mother tongue". Aural communication in the rest of the animal kingdom is limited to coarse sounds that we simply name as moos, grunts and hee-haws. But it's not going to be long before we lose our monopoly of speech.

The best machines could do in the past were beeps and alarms. Those of us who have lived through the times of early fixed line modems can recall the staccato of beeps as they tried to handshake and establish a connection to a server somewhere on the internet. Of course, machines also talk among themselves silently, by parsing bits and bytes. But now the time has come for machines to talk directly to humans via human speech.

Building My Own Development PC

Achieving Meteor 2-second rebuild time for £830

Building My Own Development PC

This was my purely hardware solution to the problem of slow Meteor build times.

When I decided to get into development I was adamant that I wasn’t going to run out and buy the latest and greatest in hardware until I actually knew how to code and knew what my requirements were in the long term.

So I went out and bought a used 15" Acer laptop for £150. It had the following spec:

  • Memory: 6GB RAM
  • Processor: Intel Pentium CPU 6200 @ 2.13GHz (Dual Core)
  • OS: Ubuntu 16.04.1 LTS 32-bit
  • Storage: 153.5GB HDD

With this setup, I saw rebuild times of 15-30 seconds (including the browser refresh) of a side project using Meteor 1.4, React and a Mongo-db instance with around 1500 records. I found these times to be excruciatingly slow when it came to making multiple changes to my code and waiting to see the results. You can see the initial version of the project I was working on here.

The Four Stages of a Developer

Development is more than just writing code

The Four Stages of a Developer

Technology is changing so fast that it's becoming hard to keep track of what's new or where it's going. It's typical for a developer to invest a few weeks learning a framework, a productivity tool or a new language, only to be told to her annoyance that there's something better and shinier that has came out just two days ago. Often there's no clear-cut comparison to suggest that one choice of technology stack is better than another. Developer skill-sets, community support, open libraries, documentation, cost, and application requirements are some factors that influence that choice. The problem has become so acute that some developers spend days or even weeks researching and get indecisive. Wouldn't it be nice to have a place that introduces technology to beginners?

When I say "beginner" I don't mean in the sense of someone in college or just starting his career. You could have years of experience in one technology and still be a beginner in Data Science, Big Data, Virtual Reality, IoT or any of dozens of new technologies that are coming up. I've found from personal experience that often initiations are in the form of Getting Started Guides, Setup & Installation Guides or Hello World examples. This fails because it's telling folks how to use something rather than explaining what it is or why it's relevant.

Why, How and What of Custom SoCs

An opinion

Why, How and What of Custom SoCs

Ever watched the Ted talk by Simon Sinek, How great leaders inspire actions? Not yet? Then I encourage you watch this 20-minute talk. This video covers the most fundamental thing that most companies fail to address: connecting with customers! Often companies focus on their products, going into details about the technical features, price, engineering innovation, etc. However, they fail to address the basic thing that is needed for a successful sale: Why they are offering the product? Answering this question bridges the gap between product and market. Revenue is an outcome, not the sole purpose of a company’s existence.

Let us take an example of a conventional sales pitch for the embedded computing platform: System on Module (SoM).

“We offer SoM that has a SoC, memory, power circuitry, Operating System, and BSPs, all integrated on a small form-factor board that offers you a platform for building your next embedded product”.

Sounds exciting? Well, it depends. However, it does not generate a great interest. Now, how about the following as a sales pitch?

Power and Misuse: The Case Against Aadhaar

An opinion

Power and Misuse: The Case Against Aadhaar

The world we have built around us is due to human ingenuity as well as engineering skills. Tools play an important role in this. It's not an exaggeration to say that most engineers think about the tools at their disposal before starting to give form to their ideas. To sculpt something, you need first good chisel and hammer. To build a bridge, you need precision measuring instruments. To dig a tunnel, you need a boring machine. In today's digital economy, you need connected servers, software platforms and algorithms.

Tools improve both efficiency and effectiveness. The problem with the use of tools is the intent. A knife can be used to cut fruit or to kill your neighbour. A cook and an arsonist use fire in very different ways. Now imagine what will happen when a powerful tool is created with bad intent but the public is told that it is for their good. Aadhaar seems to be in this category.

The AWS Alphabet Soup

An opinion on the diversity of cloud services

The AWS Alphabet Soup

I've just returned from AWS Summit held at Taj Vivanta, Bangalore. It was a busy day of multiple back-to-back sessions interspersed with networking over tea, coffee and lunch. The venue was packed. The sessions were heavy, at least for someone like me who has never used AWS in any big way. I was familiar with some of the terms before coming to this event but I was surprised how much more there is to the AWS platform. They say that as a developer you can focus on developing your application while the cloud takes care of everything else: deployment, configuration, scaling, security, access control, monitoring, etc. While this is certainly true in the long term, as developers we need to put in upfront investment in terms of time and effort to understand the plethora of services that a particular cloud platform provides.

They say there are 90+ services in AWS. It's bad enough that developers need to aware of all these different services at their disposal. It's worse when you consider that making the choice of the right set of services for your application isn't trivial. This is particularly hard for folks used to only on-premise software built in monolithic fashion. We have to be really clear what we mean by the word "monolithic", which is usually not properly explained in such summits.

The Story of UPI, So Far

Payments made easy

The Story of UPI, So Far

It was in December 2016 that the BHIM app was launched by our Prime Minister. BHIM couldn't have asked for better timing. It came at the heels of demonetization when all of India was focusing on cashless payments. Cash was in short supply and alternative means of payments were in demand. About two months later, YourStory carried a story about 27-year old Nikhil Kumar who had apparently built the BHIM app in just three weeks. A few days ago Nikhil Kumar spoke at a small gathering of enthusiasts at Thought Factory, Bangalore. I attended mostly to know about UPI and BHIM but also partly out of curiosity to see the man behind the app.

I am yet to install the BHIM app on my smartphone. While I'm not a Luddite who stands against the advance and adoption of technology, I'm certainly not an early adopter. Since I know the engineering side of things, experience tells me that early releases are prone to contain bugs. Particularly in today's world of MVP releases and lean/agile processes, no one waits for a well-tested product. First releases will certainly contain problems when test-driven methodologies are not followed; or test automation has been sidelined due to more pressing delivery deadlines. So I haven't been using BHIM but I certainly wanted to know what it was.
