As you age, you become a skeptic. Everything feels like re-runs of the past where something or the other has gone wrong; déjà vu. You are steeped in confirmation bias; you would have had enough time to search for evidence that confirms your priors; you become inflexible. Life would have punched you hard many times … Continue reading Old and not jaded

Oscillating between extremes
Whenever we hear a life story packed with wisdom, our reaction oscillates between two extremes. Either we go—oh man, this is so true; I can completely relate to this. Or, we say—there is no way this can be true; there is this one instance in my life that negates this story. We take the story … Continue reading Oscillating between extremes

The first 90 days
There is an expectation in startups that once a leader joins them; they should have a big win in the first 90 days. I believe this is a wrong expectation to have and to set. A new leadership hire in a startup should be spending their first couple of months in learning and assimilating the … Continue reading The first 90 days

Composers over creators
In a startup, there is an emphasis on creators and builders. This stems from the fact that a startup attempts to challenge the status quo, and hence you need innovative thinkers and builders who can do more with less. This line of thinking is right in spirit but can derail your execution if taken literally. … Continue reading Composers over creators
Democratizing the store of value
What is a store of value? A store of value is an asset that does not lose its value over time. Take, for example, gold.

Your true edge
What is your edge? Conventional wisdom says there are qualities that make one successful—hard work, persistence, curiosity, attention to detail, yadda, yadda. All these are good. No doubt, one has to imbibe these. But, these are table-stakes. If you know them, so does every other person. If you do what everyone else does, at best, … Continue reading Your true edge
The next frontier
When you read the history of humankind, you can see that our advancements have come from exploring(and conquering and inhabiting) novel lands and exploiting (the newly found) natural resources. This is illustrated in books like Sapiens and Guns, Germs, and Steel. Until the 19th century, the pace of these explorations was slow and gradual—there were … Continue reading The next frontier

It is challenging to define what quality code is. It is tough to come up with quantifiable metrics on quality code. … Continue reading Does code quality matter?
Communication Architecture
Organizations do not give attention to their internal communication architecture. Internal communication evolves organically. Deliberately designing the internal communication architecture makes a difference. By internal communication architecture, I mean: How does information flow? How do team members communicate with each other? When do they communicate? What is the medium they use for communication? A decoupled(push-based … Continue reading Communication Architecture
When Not to Abstract
Software developers love abstractions. It is satisfying to hide the perceived ugliness and complexity of the underlying system in a so-called easy to use, beautiful interface. Also, abstractions are considered a good design practice. The abstractions that I am referring to are those along the lines of structural design patterns like adapter and facade. ORM … Continue reading When Not to Abstract
Fighting FUD

The three pillars of scalability
The three pillars of scalability are statelessness, idempotency, and coding to interfaces. If you keep the above three in mind, your application can scale a long way with your users. Of course, I am not implying these are the only three things to keep in mind while designing scalable applications. Statelessness: If an application does not store … Continue reading The three pillars of scalability
How do I Know I am Right?
TLDR; there is no way. One thing the Coronavirus crisis has made vivid is that no one knows anything for sure. The fact that no one knows anything bubbles up every time there is a crisis.

Wild Wild World of External Calls
Today, while developing software, external calls are a given—your code talks to external HTTP services, databases, and caches. These external communications happen over networks that are fast and work well most of the time. Once in a while, networks do show their true color—they become slow, congested, and unreliable. Even the external services can get … Continue reading Wild Wild World of External Calls
Centralization and Decentralization
Top management loves centralization. Rank and file prefer decentralization. Why? Imagine you are the CEO of a company with multiple teams. Teams need software to do their work.

Murphy’s Law Of Software Abstractions
All software abstractions, sooner or later, leak. When this happens, it hurts. To drive a car, you need not know how it works internally. The mechanics of an automobile is well abstracted from the driver. Similarly, software libraries, tools, and frameworks promise abstraction to the engineers using them. They promise that one can use them … Continue reading Murphy’s Law Of Software Abstractions

“Intentionally” Leaky Abstractions
Software abstractions that developers create should leak enough to let non-developers design the right product experience. Eons back in internet history, Joel Spolsky wrote a post on leaky abstractions. The gist of the writing is that even though we create software abstractions to make life easy, they somehow unintentionally leak through. With technology getting a … Continue reading “Intentionally” Leaky Abstractions

When I was working on Kwery, a lot of people used to ask me - Why are you not trying to build a team and raise money? The niche market that Kwery served was not amenable to VC money or building a team. Kwery was an experiment in creating a single person lifestyle business. Market … Continue reading Market Size
Poor Man’s Anomaly Detection
You have a feature where if someone signs up on your product, you create a wallet for that person and top it up with complimentary money. Your organization swears by micro-services; hence sign-up logic is in one service and wallet creation and crediting is in another service. Once a user signs up, sign up service … Continue reading Poor Man’s Anomaly Detection
Startups and VC La La Land

Deviation From Expected
Someone sitting at a distance asks for the water bottle near me. I pick up the bottle and throw it at that person. Surprisingly, the cap is not screwed. Water splashes all over. When a bottle has its cap on, we usually expect it to be tightly screwed. When something deviates from the expected, unless … Continue reading Deviation From Expected
Conventions
Most programming languages have conventions. These could be for naming or code patterns. How does this help? A simplistic view is that it helps to keep code consistent, especially when multiple people work on it. A deeper way to look at this I believe is in reducing the cognitive load. In cognitive psychology, cognitive load … Continue reading Conventions
Anti Features
When evaluating new technology, framework or library; a lot of importance is given to the salient features. While it is very important to know the positives, the negatives usually tend to be glossed over. Being aware of the shortcomings of a framework gives one the ability to anticipate problems down the road. For example, let … Continue reading Anti Features

Testing legacy applications
When contemplating on introducing automated testing in legacy applications, it is easy to get bogged down in terminology; unit testing, integration testing, regression testing, black box testing, white box testing, stress testing, etc. Quite a bit of time is spent in debates on unit testing versus integration testing, I have written about this before too. … Continue reading Testing legacy applications
Build Versus Buy
Consciously or unconsciously, as software engineers, we perennially take build versus buy decisions. It might be as trivial as copy-pasting code from somewhere versus racking up our brains to write our own; using an already available library or creating one from scratch; using a time tested framework against designing one; building a piece of software … Continue reading Build Versus Buy
Context
Sapiens, the book, gives a fantastic perspective of the context in which today's religions, society, and social practices evolved and how in the current context, a lot of these are irrelevant. One of the core ideas presented in the book is that humanity, during evolution, favored social stability over individual liberty because trust was necessary … Continue reading Context

Unit test – purist versus practical
Whenever you ask a question on unit testing in a forum, there is always that one person whose only job is to point out what you are doing is not unit testing but integration testing. It is important to know the difference but it is more important to not lose sight of the goal, ensuring … Continue reading Unit test – purist versus practical
Fighting change
In my new workplace, I was assigned a brand new shiny MacBook. My first reaction was to ask for an Ubuntu laptop. My brain justified by giving several reasons, it is developer friendly, software that you run on a server runs as is in Ubuntu, etc. I was almost about to voice this opinion, but … Continue reading Fighting change
Altruism FTW
Have you observed the way Google maps asks for info about local joints and places? They word it in such a manner that it sounds like you are helping others to make an informed decision along the lines of "Give us more info to help others". What they are doing in effect is appealing to … Continue reading Altruism FTW
A little extra effort
I was sauntering on Church Street and came across a used book store. It had been long since I had been to a physical book store, hence ventured in. I started browsing around. I have been wanting to read Shoe Dog for quite sometime. I asked the proprietor did he have a used copy of … Continue reading A little extra effort
Selfie
Let us say that you want to execute a job periodically, what comes to your mind first? If you are familiar with Linux, I can hear your screaming cron. Well, no doubt about that, cron is great, but what if I told you there is another approach which you can take to execute periodic jobs? … Continue reading Selfie
SQS versus Kinesis
A lot of people are confused between SQS and Kinesis. In some ways, both act as a queue, but there is a massive difference between the two. SQS is a queue, adheres to FIFO and promises at least once delivery. Kinesis is a distributed stream processor. A simplistic and hand-wavy way to think of Kinesis is like … Continue reading SQS versus Kinesis
Release early, release often
Releasing early and often can make the difference between life and death for new age internet companies. Most of the successful dotcoms like Amazon, Google, Etsy do hundreds of deployments per day. If you are a small organization, your magnitude and frequency of deployments might not rival these big organizations, but it is always a … Continue reading Release early, release often
The Expectation Test
I got a phone lying down on road. Since I could not unlock the phone, I waited for the owner of the device to call. A couple of hours later he did call and in his opening sentence started pleading to return it. Even though he was the rightful owner of the phone, he expected … Continue reading The Expectation Test
We Are a Startup
Being part of a startup is not an excuse to shoot first and ask questions later. “We are a startup” is the most common phrase people spout when you ask them about their sloppy processes and development practices. Being a startup cannot justify having zero process or letting developers be trigger happy. Being a startup … Continue reading We Are a Startup
Let us set up an office
FreeCharge recently moved into a bigger office; this brought back fond memories of setting up the first Bangalore office. Setting up an office might not seem a daunting task, but trust me, it is. A previous company that I was part of had opted not to set up its own office and worked out of … Continue reading Let us set up an office
Nothing is sacrosanct
There is an interesting bug opened against Kafka. For those of you too lazy to click on the link and read through the description, I am reproducing it here in full.It appears that validation of configuration properties is performed in the ConsumerConfig and ProducerConfig constructors. This is generally bad practice as it couples object construction … Continue reading Nothing is sacrosanct
At what cost?
I happened to read the comic by zenpencil on Jim Henson yesterday while reminiscing on the comic by the same artist on Bill Waterson's advice. Both the comics have the same essence of escaping corporate drudgery and following your dreams. Also yesterday, I watched Inside Llewyn Davis. Inside Llewyn Davis is a melancholic movie that … Continue reading At what cost?
Requirements
We had an admin interface from which people could download an Excel report. One day, we got a mail saying that the report format is Excel version so and so and it does not work with new Excel versions. The scramble began to find out which version of Excel was used, which version our app … Continue reading Requirements
Designing for failure
In the world of software, failure is a certainty. Servers go kaput, databases go down, processes go out of memory, things break all the time. You can categorize software as good or bad based on how they behave in these adverse scenarios. I am not trying to imply that software has to be resilient to … Continue reading Designing for failure
Poor Cannot Eat Roads
Rahul Gandhi allegedly made this statement. It is sad that an armchair, untrained economist like me understands the significance of roads while someone who is poised to lead India does not. Check out this vice documentary on truckers in West Africa to get the connection between roads and economy. Jim Rogers, the author of the excellent book … Continue reading Poor Cannot Eat Roads
Moving up the value chain
In the gym that I go to, there is a guy whose job is to sanitize(spray, clean, rub etc) the equipment after each person uses them. I always pity him and think how boring his job is. How can this person move up the value chain? The other day, people at the gym were opening … Continue reading Moving up the value chain
Consumer tech
I was reading this article about a startup that is launching satellites for imaging the earth. A line from the article stuck with me, the startup is leveraging technology developed for consumer devices like laptops and mobile phones in their satellites. This is a reversal from the olden days where technology that was developed for … Continue reading Consumer tech
Go lang
Last round of the recently concluded stripectf was in Go lang. This gave me a good opportunity to familiarize myself with the language. Even though my native programming language is Java, I have worked professionally in JavaScript, Perl and PHP; dabbled in Python for my personal projects and can manage to read Ruby, Lisp(and it's … Continue reading Go lang
Startup test
Where does your startup stand on the below? Do you have version control? Do you back up data(server data, db data, etc)? Can you build using a single command or prosaically, do you have build scripts? Can you deploy code to production in a single click/command? Do you have different staging environments like dev, qa, … Continue reading Startup test
Suckers for simplicity
Let me lay it out straight in the beginning, we Indians are big time suckers for simplicity in others. It is not that we ourselves aspire to be simple but attribute unnecessary importance to it in others. Just that virtue is enough for us to weave magical stories around a person and see him as … Continue reading Suckers for simplicity
Government regulation of muliplexes
Recently I read in the newspaper that Karnataka government is planning to regulate multiplex movie ticket prices. This sounds like sweet music to ears right? Why would someone not be happy to pay a lower price for anything? I feel this move smacks of licence raj. First of all, government has absolutely no role in … Continue reading Government regulation of muliplexes
Future is in the photos
I was going through the VC interaction posted by Everpix guys. If you go through the letters, you see this repeated a lot, "You guys are in a crowded space which the biggies(Facebook, Dropbox, Google, Apple, etc) are after". Everpix is/was a service to store and organize photos. Why is this such a hot space? … Continue reading Future is in the photos
Path of least resistance
I fractured my leg and Pavitra wanted to send the x-ray to my brother in law who is a doctor. He insisted on her not e-mailing but sending it through WhatsApp. I do not use WhatsApp because I do not have a smartphone(sic, sic) but almost all of my friends are on WhatsApp these days. … Continue reading Path of least resistance
AAP, an Indian e-com startup
There have been multitude of blog posts/tweets comparing AAP to a startup. I am not sure about the comparison in general but there are eerie similarities between AAP and the Indian e-commerce(e-com) startups of the yesteryear. 1. A lot of Indian e-com startups where founded by IITians and just this IIT tag was used by … Continue reading AAP, an Indian e-com startup
The disconnect
I used to sit next to the CS(Customer Service) team for sometime and I heard them instructing certain steps to customers to redeem campaign codes the second time. The dev team had put some extended efforts to exactly prevent this sort of scenario, these campaign codes were not to be redeemed twice. Why this sort … Continue reading The disconnect
Hands On Manager
When I was new to the software industry, I always used to wonder why managers and leads delegate and ask for updates instead of being hands-on. This article is dedicated to the young novice naive me. Let us take a hypothetical manager in an organization who has taken upon herself to deliver a feature. … Continue reading Hands On Manager
What can one person do?
Someone posted a mail to a mailing list that I am part of asking us to enroll in the electoral list and vote for Narendra Modi. As expected, there were a deluge of "I am smart ass" replies like "What can one person do", "I voted in the last election, but what has changed" etc. … Continue reading What can one person do?
Appraisals
Employee appraisals are a cause of butt ache in almost every organization. Majority of the people I have known/worked with hate this time of the year. In most of the places, appraisals are done in an ass backward way, where in, during some pre defined interval, you fill a form with all the potions you … Continue reading Appraisals
Collaboration tools
Anyone who has been part of a team, be it as an individual contributor or as a lead/manager, would sense a feeling of deja vu after reading this succinct post. I personally have seen this being played in almost every organization I have been a part of. Having been on both sides of the table, … Continue reading Collaboration tools
API
Whenever I hear about the government upgrading some utility website, I die a bit inside. I am strongly of the opinion that the government has no business to be in the business of building end user utility websites. A government should act as an enabler, not as a provider. How does this apply to utility … Continue reading API
To move or not to move
In the initial days, when I was trying to bootstrap the FreeCharge tech team, my team members were always trying to make me move us away from svn to git. For the past couple of years, if you have not been living in a cave somewhere without a net connection, you for sure know that … Continue reading To move or not to move

Be Vocal
Fresh out of college, in my first company GXS, after our training, me and another guy were put into a legacy maintenance project. It was atrociously boring. A couple of weeks into it, I told my colleague that I am going to talk to the manager regarding this. It was a pretty bold step going by the … Continue reading Be Vocal
Work from home
Recently, there has been a brouhaha in the tech community over Marissa Mayer's views on work from home. As an individual tech worker, it is very appealing to side with work from home, and going by the community's reactions, I would say that I am not in the least surprised. But, when you look at it from … Continue reading Work from home
Letting go of perfection
The dark side of perfectionism. Being a perfectionist is all the rage these days. Perfectionism has a dark side to it, which gets glossed over. When you are new to something, perfectionism acts as a hindrance. Many times, you know that you cannot dedicate wholly to something. In this scenario, perfectionism prevents you from starting—your … Continue reading Letting go of perfection
Mental model of systems
One beautiful Sunday evening our quartz jobs running inside tomcat server started to freeze. At the same moment, tomcat went kaput. I sshed into the server and started poking around the logs. No error in logs. Hmm, ok. Checked the system health, again stats looked hale and hearty. Now, what do I do? I started to reason around … Continue reading Mental model of systems
The social taboo – body and mind
I just finished reading this and my mind was contemplating over the society's taboo of using your body to advance yourself in life. I do not think Sasha Grey's parents adore their daughter's achievements in the adult film industry but I am sure Nate Silver's parents are proud of his mathematical acumen. The world today is … Continue reading The social taboo – body and mind
The Algorithm and Data Structures Conundrum
Hacker news denizens have a penchant for articles on hiring. Every once in a while, a post appears on the home page followed by a passionate and vituperative debate. People conversing on this can be divided into two camps; one argues that math, algorithm and data structures are critical and interview candidates should be quizzed … Continue reading The Algorithm and Data Structures Conundrum
Programmers and movies
I just finished watching Looper and really loved it. In the beginning, for sometime, my brain was scrambling around like a headless chicken trying to fit things together. After settling into the movie for about half an hour, things started to make sense like a mist evaporating from a glass pane as the sun rises up … Continue reading Programmers and movies
Gandhians With Keyboards
6th January 1980; young, 20 something artist; supremely gifted with a melodious voice; has no connections in the entertainment industry; zilch sugar daddies who can put her in touch with the right people in the recording business. How can this artist unleash her hidden talent on the unsuspecting world? The same situation forwarded to 6th January 2013. Records her … Continue reading Gandhians With Keyboards
