In the last 40 days I have spent 160 hours meditating and it’s been the best investment I’ve done in years. Here is why. Earlier this year I came across an interview with Yuval Harari in which he talked about Vipassana, a meditation technique that he has been practicing for 17 years. I found it interesting that a lay person would spend two hours per day and a full month per year meditating, so I looked for more information and this is what I found: you learn the technique by attending a ten day course where all you do is meditate for ten hours a day.
AI is now beating human Go champions. From the article, on the fear of building something more powerful than ourselves: Kwon even went so far as to say that he is now more aware of the potential for machines to break free from the control of humans, echoing words we’ve long heard from people like Elon Musk and Sam Altman. “There was an inflection point for all human beings,” he said of AlphaGo’s win.
You probably have at least a skill or two that you would like to improve. What kind of exercises do you need to do to get better as fast as possible? There are people who seem to learn and progress much faster than others who have been at it for years. Why is that so? K.

Why is it bad? Opening my inbox and seeing all those email sitting there and looking at me is frustrating and makes me feel guilty. It’s also time wasting because less than 1 out of every 20 emails I receive are so contrived or life changing that I need to read them multiple times. A consequence of being a time wasting activity is that I lose time that I could spend in other activities that I enjoy more like continuing my Division by Zero webcomic.
Are you going to college and planning to become an engineer? After a few years there here are 5 tips that I’ve got from the trenches: What Be prepared to spend time understanding and think that you are stupid. Why I wasn’t born with an engineering mind.
