In recent months I have met many inspiring people. They are generous, fun to be around and solving the world’s problems. Diabetes, partnerships, waste, security, retirement – all of these are huge problems, and I met people that are doing all they can to fix these problems. I think this is the best career move […]

What you’ll learn: Investment is not about picking the right financial product (like stocks or bonds or mutual funds) There’s an investment strategy that is based on your values and relates to other goals of your life – like elimination of stress There is a way to gain from disorder and chaos, not only go […]

As you all probably know I am a fan of Bitcoin, but I am not that much of an alt-coin guy. What I mean by that is that I think that a main property of money is that it is universal means of exchange. It is good that you can store your wealth as savings […]

It really helps, especially with […]

The evocative video made by conference organizer tried to convince the audience that the hacker campgrounds are a Dutch tradition – as well as tulips, windmills, Gouda cheese and wooden shoes. Since 1989, every four years hackers gather in a traditional Dutch style campsite. Imagine a large music festival, substitute concerts with tech lectures and […]

A few days ago I was sending my friend a payment of 1.2 BTC. My account had only slightly more than this amount available, not even enough for recommended transaction fee. Instead of borrowing or waiting for a miner to generate more, I decided I would push a transaction with a much smaller fee to […]
