Blockchain tech, especially smart contracts, are the hot new “internet”. Post the creation of Bitcoin, we’ve seen the rise of the public smart contract system Ethereum and several private systems like Linux Foundation’s Hyperledger. These distributed ledgers have become the brand new foundation to build apps on. This is as app developers hope to leverage the additional trust that these ledgers are supposed to provide by virtue of their distributed nature.

Can we have a signin/signup flow that is email-based and passwordless similar to a “forgot password” flow but where the URL will work only for the initiator, and only once per signin? This is the scheme I’ve implemented on Patantara and I describe its innards here.
Recently, many techies have spilt words against doing the Google interview process. Broadly they feel their real and demonstrated abilities are not being valued. The most famous of these cases is Max Howell - the developer of homebrew - being rejected in the interview. Following Google, Amazon and the like, much smaller companies have also begun to subject interview candidates to such “problem solving exercises” - either on a whiteboard or within test environments such as HackerRank where you can be rewarded for coming up with the wrong answer quickly instead of the right answer slowly. These same candidates would speak up against these companies as well, had they interviewed there. Is there a real problem with this interviewing technique or are these candidates crying sour grapes?
Traffic in any major Indian city can seem crazy to an outsider. Crazy, scary, impossible, noisy, unruly, chaotic, .. and you can keep on rattling adjectives without ever ending up in a jam. Of these cities, Chennai is perhaps the craziest.

The recent Wired interview between Joi Ito, MIT Media Lab head, Scott Dadich, chief editor of Wired and the US President Barack Obama on artificial intelligence brought many perspectives into one room. The discussion is a great read as it covers the morally ambiguous ground that we might need AI to inhabit when we put them into autodrives, the role of government in funding and checking AI research, and … Star Trek. As a techie (and trekie), it is hard for me to resist the temptation of having a general AI at my disposal. However, what would the big picture be like? Would we be much better off with general AI all around us? Would AIs end up taking over the world, as is usually painted in dystopian science fiction, leaving us to fight to survive … maybe? Would I want to be in a world with general AIs all around, or would I find that world wanting?
When we begin working on a problem, one of our main tasks is to build a theory about the problem space so that we can capture and communicate our understanding about it to others and to machines. Given that when we begin building these theories we might know only a few parts of the elephant and not the whole elephant itself, what chance do we stand to discover the whole elephant if our starting point is a few limited perspectives? In this post, I share an example of how to arrive at higher level theories about a domain via bottom up exploration using systematic beta abstraction.
In the movie “The Martian”, Matt Damon plays astronaut Mark Watney who gets stranded on Mars and makes history by practicing open defecation and growing potatoes using his own shit as manure on Martian soil.
ReactJS is gradually moving towards a purely functional style of specifying
application views. In recent versions, you’re encouraged to use a pure
functional syntax that maps a view’s props to the appropriate virtual-dom
components. Combined with Flux, this approach is getting closer to what is
already established in the Elm world, where it is referred to as The Elm
Architecture. This is particularly visible in the increasing
emphasis on working exclusively with
props and avoiding
rendering React components, and piping all inputs and events into the
