Presents an anatomy of a killer mobile app

6 Key Success Factors Behind Uber Growth



Taxicabs were invented to provide easy travel solutions to everyday working class people who either had limited transportation options, or a need to ride in style without having to drive themselves. The industry has been around since the 1600’s when the horse and buggy was used to transport individuals in Paris. It wasn’t until the 1800’s when the trend carried over to the US and other countries, becoming most popular in the city of New York. The trend started after mass development of the automobile came into play. People saw an opportunity to loan automobiles out to create competition for the horse and buggy industry, in which they ultimately succeeded.

The first taxis cabs that came on the market were battery operated vehicles, in which the batteries weight upwards of 800 pounds. By 1899 the taxicab became so popular that there was an introduction of 100 taxicabs onto the streets of New York City alone. By the 1900’s more than 600 additional taxicabs, as well as a host of privately owned taxi companies came into play in the same city.

I didn't realize there was a science to being lucky, but it does seem that this theory makes a lot of sense.

Be lucky - it's an easy skill to learn



Those who think they're unlucky should change their outlook and discover how to generate good fortune...

A decade ago, I set out to investigate luck. I wanted to examine the impact on people's lives of chance opportunities, lucky breaks and being in the right place at the right time. After many experiments, I believe that I now understand why some people are luckier than others and that it is possible to become luckier.

A technical explanation of Bitcoin

How the Bitcoin protocol actually works



My aim in this post is to explain the major ideas behind the Bitcoin protocol in a clear, easily comprehensible way. We’ll start from first principles, build up to a broad theoretical understanding of how the protocol works, and then dig down into the nitty-gritty, examining the raw data in a Bitcoin transaction.

Many thousands of articles have been written purporting to explain Bitcoin, the online, peer-to-peer currency. Most of those articles give a hand-wavy account of the underlying cryptographic protocol, omitting many details. Even those articles which delve deeper often gloss over crucial points. My aim in this post is to explain the major ideas behind the Bitcoin protocol in a clear, easily comprehensible way. We’ll start from first principles, build up to a broad theoretical understanding of how the protocol works, and then dig down into the nitty-gritty, examining the raw data in a Bitcoin transaction.

Understanding the protocol in this detailed way is hard work. It is tempting instead to take Bitcoin as given, and to engage in speculation about how to get rich with Bitcoin, whether Bitcoin is a bubble, whether Bitcoin might one day mean the end of taxation, and so on. That’s fun, but severely limits your understanding. Understanding the details of the Bitcoin protocol opens up otherwise inaccessible vistas. In particular, it’s the basis for understanding Bitcoin’s built-in scripting language, which makes it possible to use Bitcoin to create new types of financial instruments, such as smart contracts. New financial instruments can, in turn, be used to create new markets and to enable new forms of collective human behaviour. Talk about fun!

Yet another missive on how to build great products....

How to build great products



...three buckets to categorize any given feature:

A gamechanger
People will want to buy your product because of this feature.
A showstopper
People won’t buy your product if you’re missing this feature, but adding it won’t generate demand.
A distraction
This feature will make no measurable impact on adoption.
If you believe that sales fix everything, it follows that most startups fail because they don’t ship a great product in a growing market before they run out of money. Assuming you’ve picked an explosive market, how do you go about building a great product?

Building great products is hard, but the difficulty is greatly exacerbated if you have no good model for analyzing products and features. Without a model you’re left with a never-ending stream of feature ideas and half-informed shots in the dark. Some people can pull this off because they start out with a phenomenal product intuition. But most people aren’t blessed with this superpower on day one..

Some thoughs on the Freemium Model

The Anatomy of Profitable Freemium



Choosing the freemium business model can be brilliant or deadly. The difference lies not only in the execution of the marketing, but also in the nature of your product and the design of your business. Can you coordinate all three to become sustainably freemium by making a profit?

Summary:
  • Freemium requires a business to maintain two value propositions with a well-designed interaction between the two.
  • The premium offering can deliver different kinds of value. You should choose the most profitable one you can under your constraints, which best fits the value your product delivers.
  • Using a free car analogy, the kinds of premium value (types of freemium) include: Cargo Freemium, Airbag Freemium, Bomb Freemium, Cruise Control Freemium, and Bells & Whistles Freemium.
  • Each type of freemium has unique risks as well as market and funding requirements in order to be sustainably profitable.
  • Any of these types of freemium can be implemented poorly. Some types may not work with your product. Correctly implementing any of these types of freemium requires a deep understanding of the value of your product.
  • Entrepreneurs should be convinced that freemium is the right choice for their product/market, choose their type of freemium out of knowledge (not fear or ignorance), and re-evaluate this decision regularly.
  • Freemium can be extremely beneficial for gaining market share, but if it can’t create sufficient conversions to a premium offering, it isn’t sustainable.

Interesting thoughts on software maintainability

The myth of maintainability



"Will this be maintainable in the long term?” - a comment on every code review ever

I have an allergic reaction to this question. It is often used when Developer A wants to add a non-trivial component to the codebase. The room (or code review) will always have Developer B who springs up the dubious concern of maintainability. Proceed with caution.

What do we exactly mean by maintainability as developers? Will the code be easy to understand for the next person to read it? This is readability, which could be seen as a factor in maintainability, and is valid. The more pressing interpretations tend to be along the lines of extensibility, abstraction, and hand-wavy higher level design or architecture.

The problem with the latter interpretations is the possible misunderstanding of why we write software. Software exists to drive a business need, add business value, and in the end — generate revenue. Let’s not waste time (and these discussions usually end up just wasting time).
