The value of comments and references depends on the software context. If inexperienced people are expected to be editing or reading the code they're more valuable. However, they are expensive to keep in sync with changes to the impleme

It's hard to do objective research. Some studies try A/B tests on student volunteers. But then this setting is clearly different to professional teams working on a project for a long time. The value of new methodologies, languages

Great points! FAANG companies like to manage people without giving negative feedback. This can be very confusing if you are used to explicit feedback and come from a more direct culture. "Listening to your manager" can be difficul

Protobuf actually has a canonical text format. It's easy to produce in C++ or Java https://developers.google.com/protocol-buffers/docs/referenc... The format has much less extra syntactical noise than JSON. F

Enumerating what we want from notation helps us understand how far we are from the ideal. The whimsical introduction of Notation to talk about notation makes it practical. Given a domain in mathematics, adding notation (e.g. modulo arithmet

Agreed that the whitespace elision is overly complex and too prescriptive for a small issue. Either whitespace is important or not; if not it doesn't matter so there should be no special handling, and if it does - the special handling

The big platform companies see engagement and growth metrics for all startups, not just the numbers they are pitched. The public didn't expect Instagram to be a success - Facebook had more information. This information asymmetry is a b

During the crash, if the market were functioning normally, people could have bought cheap ETH in the ETH-USD market and sold it at nearly the normal price via the ETH-USD and BTC-USD markets all without leaving GDAX. Their outage page has t

It seems that the price plummet only occurred on the GDAX ETH-USD market. Even the GDAX BTC-ETH market hasn't the spike. Normally there are many bots ferrying liquidity between these markets so this suggests that the ETH-USD market was

The question is a logical fallacy. I worked at an IB and even in 2011 traders were acutely aware of the benefits of technology and eager to invest in it and embrace it. Many of the answers here are regurgitations of techno-utopian talking p
