This Week I Learned 2018 - Week 17

Last week post or something from the past instead.

Humour aside, I've known two persons (a tech guy and a lecturer) who don't even have a mobile phone, let alone social media accounts. Yes, they are on the rather extreme cases but that was due to their own personal stands and life philosophy. While there have been quite a lot of minimalist life style movement these days but little emphasis on digital world. As usual, moderation is the key here. Too much of everything will cause unwanted disturbance and distraction to your personal and working life.


The Playoff Rondo is part stats and part myth although the stats don't tell the full story. But it's quite entertaining to watch him play, especially the playoff and with big centers.

Plan B before you turn 40. (via HN) Relevantly, experiences on those over 50 who have been laid-off from the tech-force seemed quite positive, life still goes on although on different path. Well there are differences different between Western and Asia countries, this is just part of your work life, especially for those working in tech. Practice minimalist life style, live below your means, exercise and keep healthy, and do what you love. You have to agree with, web development is so accessible these days. Anyone good basic knowledge of English and keen persistence, they can build up the system fairly quite fast. Furthermore, as you aged, priority in life changed as well as your health. Moreover, older tech guy tends to question more and call out BS.

Where SCRUM is not the right choice. (via Reddit) The discussion in the Reddit tells a lot of the horror or abuse stories where SCRUM was implemented literally. It does not work for software team with different project and don't share the SAME backlog. If you have different products, you can't implement SCRUM within the same backlog! Period.

Friendship’s Dark Side: ‘We Need a Common Enemy’. It's a common knowledge but right now it have been proven that "Xenophobia and in-group bias go hand-in-hand". Average fall-outs withing the social group is around 7-plus months. Interesting read.
