There are many different ways to keep my digital social life healthy and flourishing, so why should I use the service that I like the least?
Facebook. The hottest internet site during my high school and university. The site to see what my friends are up to. The site to chat with others. The place to meet people with similar interests.
Messenger. The app to chat with friends. Deep talks, small talks, flirting, dating, sharing memes, sharing photos, sharing links.
This article is not about a deep analysis of the pros and cons of Facebook. It is not my professional…
My parents, grand-parents and most of the classic literature tells me about the joy of getting a letter. How amazing it feels and how important getting a letter is. In most of the stories, getting a letter is the trigger of emotions and following actions for the literary character. If we try to describe what a letter is, it is just information shared with us from someone else. Nowadays, we get hundreds if not thousands of such informations per day in the form of chat messages. But why doesn’t it feel the same as the letter seems to do?
EDIT UPDATE: After sharing this article, I received a comment from a friend of mine directing me to the following study debunking a lot of information included in the book Why we sleep. Please if you consider reading Why we sleep, read this article first.
Sleep is non-negotiable. Without sleep, we die. Insufficient sleep negatively affects every aspect of our lives. There is no catching up on not sleeping a single night. Sleeping less to achieve more in life is a lie. Sleeping enough makes us healthier, more productive, and more efficient in all areas of our lives.
If I read this book while I was a teenager, I would have ended up as an engineer. There is no doubt about it.
Every chapter walks you through the story about how a machine that made the modern world possible came to being. It takes you through the lives and troubles of people developing these machines so you feel the thrill and excitement of building them yourself.
Every chapter focuses on the precision needed to build the machine and with each chapter the needed precision increases.
You create a single masterpiece. You become famous. The masterpiece gets destroyed. …
Yuval Noah Harari is best known for his book Sapiens which I enjoyed reading a lot. I would recommend reading Sapiens to anyone. Harari’s second book — Homo Deus did not have such an impact on me. As I am a huge fan of new technologies and think about their potential impact on the future, Homo Deus felt like a well-written summary of what I have already read. Nevertheless, Harari did a decent job of putting it a perspective that made me think about the coming decades from a different angle.
Sapiens described where mankind came from, Homo Deus previewed…
People love absolutes. A thing is either black or white. Not both. Definitely not a rainbow. That is very difficult to measure properly and thus impossible to manage.
In my job as a data analyst I am often asked for a simple total number. An aggregate. A single metric to rule them all. In the domain of web analytics, this single number is usually the conversion rate. How many people who visited my web have done as I wanted them to?
On our fake website we have launched two themes, one featuring the magic of Harry Potter and the other…
I love being proven wrong. It makes me realise there is still a lot I need to learn, especially in the way I am building my opinions. This book does just that — it helps you to revisit the way you create opinions.
Hans Rosling starts the book with 13 questions about the world checking your general knowledge. What is the life expectancy of the world today? How many of the world’s 1-year old children today have been vaccinated against some disease? With questions like these he proves many of us to be wrong about our image of the world.
We are bombarded with data and numbers all the time. If you stick a number to it, it sounds more trustworthy — is a motto followed by many journalists when trying to support their “shocking” revelations and catchy headlines.
Here is a little discussion between a couple of friends after one of them has read the news on the new raging virus killing thousands of people.
A: “The news says 100 000 people died of the disease TROLL-15.”
B: “That’s pretty serious man.”
A: “Yeah, we need to do something about it immediately.
C: “Where did those people die? The…
Why are people obsessed with data? What makes data so important? The data is collected, cleaned, processed, analysed and interpreted in order to get insights. That sounds cool but what does it mean? Anything that helps us make the right decision can be considered an insight. It is the piece of information which influences our decision making process to do something in a way which will maximise the rewards of our decisions.
We look how many likes our photos on social media get, how many times our blog post is read, how much money we save each month. This is…
