I already follow the videos of Jonathan Blow. And they are very interesting. (And I missing more frequent updates....:)
I am new to this kind of "infotainment", and I like it. To view Jon Blow or Casey code, is just fucking beautiful.
However, it's not the fact that he (JB) is writing a compiler that interest me the most, but the mindset, and philosophy he has for doing so. Which seem to me very close to the right thing.
I also think that writing a truely NEW compiler, is almost a neglected area, where the opportunities for doing something truely unique and magnificent is rather big. However, I fear that in the marketplace, that's sadly not always enough.
Yes it's great in many many ways. You learn new ways of thinking about code when you hear their train of though while you see the code manifest itself.
