A few people who I’ve spoken to as part of my job hunt have asked to see some “detailed descriptions” of work that I’ve done. The other day, I put together an email with some of these descriptions. I thought it might make sense to “document” it in one place (and for me, the “obvious…
Core quants and desk quants on main street
The more perceptive of you might have realised that I’m in the job market. After nine wonderful years, I've decided to shut down my strategy and data consulting business. Will start looking for a job soon. Leads and recommendations welcome (preferably email/message me off twitter) — Karthik (@karthiks) October 9, 2020 Over the last one…
Meetings from home
For the last eight years, I’ve worked from home with occasional travel to clients’ offices. How occasional this travel has been has mostly depended on how far away the client is, and how insistent they are on seeing my face. Nevertheless, I’ve always made it a point to visit them for any important meetings, and…
Simulating Covid-19 Scenarios
I must warn that this is a super long post. Also I wonder if I should put this on medium in order to get more footage. Most models of disease spread use what is known as a “SIR” framework. This Numberphile video gives a good primer into this framework. The problem with the framework is…
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…
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…
Segmentation and machine learning
For best results, use machine learning to do customer segmentation, but then get humans with domain knowledge to validate the segments There are two common ways in which people do customer segmentation. The “traditional” method is to manually define the axes through which the customers will get segmented, and then simply look through the data…
Taking Intelligence For Granted
There was a point in time when the use of artificial intelligence or machine learning or any other kind of intelligence in a product was a source of competitive advantage and differentiation. Nowadays, however, many people have got so spoiled by the use of intelligence in many products they use that it has become more…
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,…
Housewife Careers
This is something I’ve been wanting to write about for a very long time, but have kept putting it off. The ultimate trigger for writing this is this article about women with children in Amazon asking for backup child care at work. Since this hits rather close home, this is a good enough trigger to…
Just Plot It
One of my favourite work stories is from this job I did a long time ago. The task given to me was demand forecasting, and the variable I needed to forecast was so “micro” (this intersection that intersection the other) that forecasting was an absolute nightmare. A side effect of this has been that I…
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…
I’m not a data scientist
After a little over four years of trying to ride a buzzword wave, I hereby formally cease to call myself a data scientist. There are some ongoing assignments where that term is used to refer to me, and that usage will continue, but going forward I’m not marketing myself as a “data scientist”, and will…
Networking events and positions of strength
This replicates some of the stuff I wrote in a recent blog post, but I put this on LinkedIn and wanted a copy here for posterity Having moved my consulting business to London earlier this year, I’ve had a problem with marketing. The basic problem is that while my network and brand is fairly strong…
Triangle marketing
This blog post is based more on how I have bought rather than how I have sold. The basic concept is that when you hear about a product or service from two or more independent sources, you are more likely to buy it. The threshold varies by the kind of product you are looking at.…
Attractive graphics without chart junk
A picture is worth a thousand words, but ten pictures are worth much less than ten thousand words One of the most common problems with visualisation, especially in the media, is that of “chart junk”. Graphics designers working for newspapers and television channels like to decorate their graphs, to make it more visually appealing. And…
Taking your audience through your graphics
A few weeks back, I got involved in a Twitter flamewar with Shamika Ravi, a member of the Indian Prime Minister’s Economic Advisory Council. The object of the argument was a set of gifs she had released to show different aspects of the Indian economy. Admittedly I started the flamewar. Guilty as charged. Thinking about…
