Going for a walk ever morning I think helped me the most. Getting sun in my eyes helps with sleep and I wake up less tired.

I also meditate and try and be mindful during the day.

I recently found something to help me be more disciplined. There's evidence it works and I will see if it works for me as I just did the exercise today.

I'm not sure how it's implemented in Ferret but Clojure's data structures are implemented as trees so there's structural sharing that happens when a vector or hash map is updated or when a new version is produced.

So the whole data structure isn't copied but only the relevant parts are added / updated in the tree and the rest is shared with the "new" data structure.

Mutable data structures are still more memory effective but I'm assuming its fine since the author has a blog post on using ferret on an Arduino Uno which has 32k of ram. https://nakkaya.com/2017/02/15/bare-metal-lisp-rc-control-us...

It's so interesting watching Rich talk. He has such a breadth and depth of knowledge and you can tell that he really took his time when designing the language.


He writes on he's blog that he thinks a lot of parts are recycled

You might wonder why I chose to make an iPhone 6s and not an iPhone 7. I had two reasons...

However, the other reason, which turned out to be far more important, is that iPhone 7 parts are pretty hard to come by in the markets. It’s not totally clear why this is, but I have some ideas. A lot of the parts come from recycled/broken phones, and so it would make sense that there just isn’t that much supply yet.

If you read his blog post he mentions that the logic board is recycled and he thinks that alot of iphone 6 parts come from recycled/broken phones.

quote from the blog about the logic board: "The one I bought is refurbished/repaired, almost undoubtedly from a real, legitimately purchased phone made by Apple that was recycled at some point."


A lot of phones stolen in the west are laundered just south of the border here in Hong Kong.


I love Brogue! Brogue's dev went though how the levels are generated in a game in the article below. Its a good read.
