How Netflix’s Customer Obsession Created a Customer Obsession This article is full of nuggets, here's one:

Based on consumer insights and learnings, do you have a product strategy that defines your hypotheses about what you hope will fulfill the trifecta of delighting customers in hard-to-copy, margin-enhancing ways?


Personalisation is not the end-game of marketing Bingo:

You may find the customer’s idea of personalisation is more akin to excellent customer service, rather than a post-purchase email offering a similar-looking jumper on sale.

Accenture sued over website redesign so bad it Hertz: Car hire biz demands $32m+ for 'defective' cyber-revamp Not sure why they expected more out of Accenture:

Among the most mind-boggling allegations in Hertz's filed complaint is that Accenture didn't incorporate a responsive design, in which webpages automatically resize to accommodate the visitor's screen size whether they are using a phone, tablet, desktop, or laptop.
Accenture also failed to test the software, Hertz claimed, and when it did do tests "they were seriously inadequate, to the point of being misleading." It didn't do real-world testing, we're told, and it didn’t do error handling.

Second-Order Thinking: What Smart People Use to Outperform 💡 Always ask yourself “and then what?”

Facebook says it 'unintentionally uploaded' 1.5 million people's email contacts without their consent I'm curious, how do you "unintentionally" write code that reads data from one system, and then convert and upload it to your servers?

How do you "unintentionally" monitor that it works correctly for 1.5 million people, and "unintentionally" fix the inevitable bugs that pop up?

Jeff Atwood True!

Of all the technical debt you can incur, the worst in my experience is bad names -- for database columns, variables, functions, etc. Fix those IMMEDIATELY before they metastasize all over your codebase and become extremely painful to fix later.. and they always do.

Software Maintenance, Understanding the 4 Types Not all software maintenance is the same, and it helps to know the difference:

Every time that you make changes to a software system, it is essential to identify the type of maintenance that you are performing. Keeping track of it gives excellent insights into your engineering practices. For example, the percentage of time that you spend in each of the four maintenance types gives you an idea of the maturity and skill level of your software engineering organization. It can also give you an idea of the maturity level of your product and codebase.

The key to glorifying a questionable diet? Be a tech bro and call it ‘biohacking.’ Not mincing words:

It's fascinating to watch the language of food consumption mutate as it travels across genders. For decades, "dieting" was the domain of women. It looked like Weight Watchers, it looked like Snackwells, it looked like South Beach, but whatever it looked like, it was always portrayed as something simultaneously necessary, shameful, pride-inducing, hated and ever-present.

The term became a victim of “gender contamination,” as Amanda Mull wrote in the Atlantic — which is “when a product or idea becomes so female-coded that men are no longer willing to engage with it.”

Instead men — and the companies that cater to them — found new ways to describe food restriction. Not “weight loss” but “performance-enhancing.” Not “look great” but “perform better.”

BBC - Future - Are we close to solving the puzzle of consciousness? TL;DR No. But this is an interesting read nonetheless, on our attempt to define what separates humans from lobsters:

From these axioms, Tononi proposes that we can identify a person’s (or an animal’s, or even a computer’s) consciousness from the level of “information integration” that is possible in the brain (or CPU). According to his theory, the more information that is shared and processed between many different components to contribute to that single experience, then the higher the level of consciousness.
