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.
JB has inspired me to design a new language domain-specific for realtime audio/DSP-applications. I have struggled with applying C++ to this field for a long time now but either you give up performance or code quality (template hell, macro cesspool or lots of code repetition). I also see lots of potential for new languages, and as long as I benefit from the new language that's reward enough. The marketplace is always a strange ultra conservative place so it's hard to design a language to please the current marketplace fixated on web 2.0 without making a JavaScript-clone with extra bloat on top.
