Why Your Annoying Friend Won’t Stop Ranting About Bitcoin

by Phil Geiger — 10 min read

This post is dedicated to people who don’t like Bitcoin and/or don’t have any yet.

Bitcoin is dead. The bubble has popped, and we can all finally move on from this insanity and accomplish some real work. The cries for Bitcoin adoption are getting desperate, exhausting, and frankly, sad. Look, the thing crashed from $20,000 to $3,200. Nobody I know uses it for purchases. Bitcoiners don’t understand economics. BTC is not money, it’s the mother of all scams, and it can only handle 7 transactions per second. Any of this sound familiar?

All of these arguments don’t matter and this post will explain why.


Black Mirror Bandersnatch: data mining your decisions

by Viridiana Romero Martinez — 10 min read

After reading many comments from friends on Facebook about the new interactive show from Black Mirror called “Bandersnatch”, I decided to watch it last night. This is not the first time watching Black Mirror, as a matter of fact, I love it! This reminds me of one of my favorite old TV shows: Twilight Zone. I still get scared when I watch the episode: “Nightmare at 20,000 Feet”, when the gremlin is on the airplane wing! (The gremlin in the movie is scarier than the one from the old TV show though).

by Wendy Leung — 10 min read

In this article, we’ll address that by covering id and type, mutable objects, immutable objects, why it matters, how differently does Python treat mutable and immutable objects, how are arguments passed to functions, and what does that imply for mutable and immutable objects. I include examples in Python3.


Could Cryptocurrencies Provide the Alpha that Algos Evaporated on Wall Street?

by Patrick Tan — 9 min read

Alpha (to use the language of Wall Street) is becoming more difficult to find in the markets. It’s a little like gold during the California gold rush of the 19th century. When news that gold was discovered, more and more people headed west towards San Francisco to make their fortunes. And while there was plenty of gold, more and more people started to know the best spots to pan for it and eventually what little gold was left had to be divided among more and more panhandlers (not the current day type of panhandlers).


My Rendezvous with Artificial Intelligence: Salt & Pepper

by Pranay T — 4 min read

These days, every organization is talking about Artificial Intelligence and its’ implementation in their products and services. I wonder how many of these claims are true and how many are just filling their marketing campaigns with buzzwords.

During my market research (read a normal stroll around the lanes of IT hubs in Bangalore), I came across various such companies in the market claiming to work on AI.

On further investigation of such companies, regarding how and where these organizations are utilizing AI methods, the results left me stupefied. The effect was not due to their amazing fancy web pages or their content; but rather the purpose of their products!
