One is a boss's view, looking for an AI to replace his employees someday. I think that is a dead end. It is just getting better to become a sophisticate, increasingly impressive but won't work. One is the worker's view, looki

In another word, it (to have runtime macro expansion) is a side effect, a compromise, a wart, rather than a design goal, right?

> That being said, I think homoiconicity is actually a useful feature, but runtime macro expansion is the dangerous part. Practically, why would you ever want a runtime macro expansion?

LISP has been singing homoiconicity as its feature. I lately start to think homoiconicity is really a wart. The macros are a system to program the code, while the code is a system to program the application. They are two different cognition

The ban is not having an issue between China and US. US can do whatever to China, and only need balance potential retaliation. There is no moral debate between countries, just power play. The ban is an issue between US government/polit

Since you are already familiar with other languages, I suggest just pick a tool that you use daily that is open source in C, and start hacking it.

It's not about the amount of time kids takes up in your life. It is about how kids changes your life forever. Your priority in life changes, then your life changes. I guess when kids leave us, we need relearn the life.

The `infix` syntax is missing from the major items. Without infix syntax, all languages are just variations of LISP -- I guess that was all the article is about.

Yes, I agree! In fact, the break through we needed is to view programming as a human cognitive operation and embrace the text, and treat manipulating text as a main component of coding. For example, I want to code foreach item in lis

Perl started with scripting, so many design philosophy are centered around scripting. Python, I think, is started with the goal of building applications. My first impression when I learned Python (around 2000) was the OOP nature of Python.

Python never succeeded in scripting. Shell still dominates scripting today. Perl is rooted in scripting.

Perl is really cursed by the past glory. People still trying to revive Perl against modern fad, for example, Python. Fad are powered by steam of live Eco-systems, which Perl once had, but no longer have. There is no real reason why Perl co
