I’ve forgotten which stage of lockdown or “unlock” e-commerce for “non-essential goods” reopened, but among the first things we ordered was a Scrabble board. It was an impulse decision. We were on Amazon ordering puzzles for the daughter, and she had just about started putting together “sounds” to make words, so we thought “scrabble tiles…

The future of work, and cities
Ok this is the sort of speculative predictive post that I don’t usually indulge in. However, I think my blog is at the right level of obscurity that makes it conducive for making speculative predictions. It is not popular enough that enough people will remember this prediction in case this doesn’t come through. And it’s…
Range of possibilities
After I wrote about “love and arranged jobs” last week, an old friend got back saying he quite appreciates the concept and he’s seen it in his career as well. He’s fundamentally a researcher, with a PhD, who then made a transition to corporate jobs. He told me that back in his research days, he…
Love and arranged jobs
When I first entered the arranged marriage market in early 2009, I had done so with the expectation that I would use it as a sort of dating agency. Remember this was well before the likes of OKCupid or Tinder or TrulyMadly were around, and for whatever reason I had assumed that I could “find…
Two steps back, one step forward
In his excellent piece on Everton’s failed recruitment strategy (paywalled), Oliver Kay of the Athletic makes an interesting point – that players seldom do well when they move from a bigger club to a smaller club. During his time in charge at Arsenal, George Graham used to say that the key to building a team was…
Statistical analysis revisited – machine learning edition
Over ten years ago, I wrote this blog post that I had termed as a “lazy post” – it was an email that I’d written to a mailing list, which I’d then copied onto the blog. It was triggered by someone on the group making an off-hand comment of “doing regression analysis”, and I had…
Ganesha Workflow
I have a problem with productivity. It’s because I follow what I call the “Ganesha Workflow”. Basically there are times when I “get into flow”, and at those times I ideally want to just keep going, working ad infinitum, until I get really tired and lose focus. The problem, however, is that it is not…
Fishing in data pukes
When a data puke is presented periodically, consumers of the puke learn to “fish” for insights in it. I’ve been wondering why data pukes are so common. After all, they need significant effort on behalf of the consumer to understand what is happening, and to get any sort of insight from it. In contrast, a…
More on statistics and machine learning
I’m thinking of a client problem right now, and I thought that something that we need to predict can be modelled as a function of a few other things that we will know. Initially I was thinking about it from the machine learning perspective, and my thought process went “this can be modelled as a…
Data, football and astrology
Jonathan Wilson has an amusing article on data and football, and how many data-oriented managers in football have also been incredibly superstitious. This is in response to BT Sport’s (one of the UK broadcasters of the Premier League) announcement of it’s “Unscripted” promotion where “some of the world’s foremost experts in both sports and artificial intelligence…
10X Studs and Fighters
Tech twitter, for the last week, has been inundated with unending debate on this tweetstorm by a VC about “10X engineers”. The tweetstorm was engineered by Shekhar Kirani, a Partner at Accel Partners. I have friends and twitter-followees on both sides of the debate. There isn’t much to describe more about the “paksh” side of…
Periodicals and Dashboards
The purpose of a dashboard is to give you a live view of what is happening with the system. Take for example the instrument it is named after – the car dashboard. It tells you at the moment what the speed of the car is, along with other indicators such as which lights are on,…
Vlogging!
The first seed was sown in my head by Harish “the Psycho” J, who told me a few months back that nobody reads blogs any more, and I should start making “analytics videos” to increase my reach and hopefully hit a new kind of audience with my work. While the idea was great, I wasn’t…
Bangalore names are getting shorter
The Bangalore Names Dataset, derived from the Bangalore Voter Rolls (cleaned version here), validates a hypothesis that a lot of people had – that given names in Bangalore are becoming shorter. From an average of 9 letters in the name for a male aged around 80, the length of the name comes down to 6.5…
Smashing the Law of Conservation of H
A decade and half ago, Ravikiran Rao came up with what he called the “law of conservation of H“. The concept has to do with the South Indian practice of adding a “H” to denote a soft consonant, a practice not shared by North Indians (Karthik instead of Kartik for example). This practice, Ravikiran claims,…
Human, Animal and Machine Intelligence
Earlier this week I started watching this series on Netflix called “Terrorism Close Calls“. Each episode is about an instance of attempted terrorism that has been foiled in the last 2 decades. For example, there is one example of the plot to bomb a set of transatlantic flights from London to North America in 2006…
Elegant and practical solutions
There are two ways in which you can tie a shoelace – one is the “ordinary method”, where you explicitly make the loops around both ends of the lace before tying together to form a bow. The other is the “elegant method” where you only make one loop explicitly, but tie with such great skill…
Why AI will always be biased
Out on Marginal Revolution, Alex Tabarrok has an excellent post on why “sexism and racism will never diminish“, even when people on the whole become less sexist and racist. The basic idea is that there is always a frontier – even when we all become less sexist or racist, there will be people who will…
More on interactive graphics
So for a while now I’ve been building this cricket visualisation thingy. Basically it’s what I think is a pseudo-innovative way of describing a cricket match, by showing how the game ebbs and flows, and marking off the key events. Here’s a sample, from the ongoing game between Chennai Super Kings and Kolkata Knight Riders.…
Astrology and Data Science
The discussion goes back some 6 years, when I’d first started setting up my data and management consultancy practice. Since I’d freshly quit my job to set up the said practice, I had plenty of time on my hands, and the wife suggested that I spend some of that time learning astrology. Considering that I’ve…
More issues with Slack
A long time back I’d written about how Slack in some ways was like the old DBabble messaging and discussion group platform, except for one small difference – Slack didn’t have threaded conversations which meant that it was only possible to hold one thread of thought in a channel, significantly limiting discussion. Since then, Slack…
