In a recent series of ground-breaking psychological experiments, volunteers were shown a second film of some people playing basketball and told to count the number of passes made with the ball.
After just a few seconds, a man dressed as a gorilla slowly walked into frame, beat his chest at the camera, and sauntered off. Unbelievably, almost none of the people watching t In a recent series of ground-breaking psychological experiments, volunteers were shown a second film of some people playing basketball and told to count the number of passes made with the ball.
Unbelievably, almost none of the people watching the film noticed the gorilla. Exactly the same psychological mechanisms that cause people to miss the gorilla also make them miss unexpected but vitally important opportunities in their professional and personal lives. This book outlines the scientific evidence and thinking behind this remarkable new phenomenon, and shows you how you can spot gorillas in your life - and what to do when you see one.

I'm still thinking of how to put the ideas he writes about into practice. I feel that's not as easy with this book compared to the other books he's written. That may be related to the subject-matter rather th I enjoyed this book. That may be related to the subject-matter rather than the author's writing. The ideas in this book are a bit more abstract compared to those in his other books. Jan 23, Renee rated it liked it.

The purpose is to show you how easy it is to keep seeing what you expect to see, but I found the book short on actual tricks to fix this. Lay in a field and watch the clouds was a bit simple. I think there could be better tactics. But maybe it will surprise me and have more of an effect. I'll update this if so. Nim developed friendships with several of the workers at the Institute of Primate Studies, and learned a few more signs, including a sign named "stone" which indicated that Nim wanted to smoke marijuana.
Nim's time here was mostly spent receiving injections after being heavily sedated. While Nim's quality of life improved at the Black Beauty Ranch, Nim lived primarily in isolation inside a pen. He began to show hostility that included throwing TVs and killing a dog.
Nim continued to show signs of the sign language he learned decades ago whenever a former trainer at the Institute for Primate Studies went to visit him. Nim died on 10 March at the age of 26, from a heart attack. The story of Nim and other language-learning animals is told in Eugene Linden 's book Silent Partners: The Legacy of the Ape Language Experiments.

American Sign Language Yerkish. I believe you should always start with tests, first, and that belief is backed up by research from Microsoft and IBM. In this case, those might look something like this:. Once that button is pressed, we should create some app state that represents the current logged in user:. Before moving on to the rest of the app, we should make those tests pass.
Do one thing per line. Do one thing per function. For example, if you need to use the value of a query parameter, you should dedicate a function to extracting the value of a query parameter from the URL rather than mix that logic with a function that uses the value. Use one variable to represent only one thing. For instance, you may be after a query string parameter value, and start by storing an entire URL, then just the query string, then the value.
Not to be confused with immutable values. Unlike true immutable datatypes such as those produced by Immutable. There are many ways that a function can cause side effects, or create a complex array of possible outcomes. The essence of any program is to take some data as input and produce some data as output. The essence of a function is to take some data as input and produce some data as output. Therefore, the simplest implementation possible is a function. If a function complies with that definition, it is easily understood:.
It also affects any other function that uses a reference to the same variable. Side effects are not obviously visible, so when they cause a bug, it can potentially be hard to trace to the root cause. Therefore, the simplest functions cause no side effects. Side effects include any state change that is visible outside the function. That includes logging messages, displaying things to the screen, and throwing exceptions. This allows your functions to obey the robustness principle:. My interpretation is a bit more general:. Wherever possible, we should avoid side effects. Such functions can be difficult to debug.
Whenever possible, ensure that your functions will always return the same output given the same inputs. This feature means that such functions are idempotent.
That is, the results of calling the function many times are the same as calling the function once. Idempotent functions without side effects have a feature known as referential transparency. That means that if you have a function call:. And your program would still work as expected. Functions which have no side-effects and exhibit referential transparency are called pure functions.
The simplest functions are pure functions. Simple to use means that the code should have a clear and focused API. The code does one thing , and it has a simple interface to accomplish that thing.
For example, jQuery accepts many different types of inputs to the jQuery function. If you pass a function, it gets triggered on page ready. If you pass a string, it gets interpreted as a DOM selector, and so on. Ad-hoc polymorphism means that inside your function, you look at the inputs, and based on their types or values, you follow different branches of conditional logic. Ad-hoc polymorphism adds to function complexity, forces you to write unnecessary conditional logic, and removes your ability to write semantic names for each different role you want a function to play.
