create my own programming language [duplicate]
If you’re interested in compiler design (“how can computer understand what codes mean”), I highly recommend Dragon Book. I used it while in college and went as far as to create programming language myself.
How can CoffeeScript be written in CoffeeScript?
This is nothing new. C compilers have been written in C. Python has been written in Python. It’s possible to use a compiler for Language X to compile a newer version of itself, with more features. It’s called bootstrapping. Bootstrapping a language Writing a compiler in its own language How do you write a compiler … Read more
How to invoke an interactive elisp interpreter in Emacs?

remove Anaconda environment with no name?
I was able to solve a similar situation by removing it using the prefix rather than the name. I.E. conda env remove -p /Users/usr/anaconda3/envs/snowflaks
What are the primitive Forth operators? [closed]
This thread covers your exact question. Here is a soup-to-nuts implementation with complete documentation. I wrote a subroutine threaded Forth targeting 68K when I was in college. I defined the runtime environment and dictionary format, then wrote some C code that boot strapped a Macintosh application that loaded a default dictionary, populated some I/O vectors … Read more
Java Threads vs OS Threads

Is there an “immediate window” in Visual Studio Code to run Javascript?
As of (at least) my current version of VS Code (1.5.2), the “Debug Console”, while debugging, lets you run arbitrary JavaScript code as you would in the VS Immediate Window. (Similar to as you would for the Chrome Dev Tools Console.)
Difference between compiled and interpreted languages?
Neither approach has a clear advantage over the other – if one approach was always better, chances are that we’d start using it everywhere! Generally speaking, compilers offer the following advantages: Because they can see all the code up-front, they can perform a number of analyses and optimizations when generating code that makes the final … Read more
What are the differences between a Just-in-Time-Compiler and an Interpreter?
I’ve always found that a more abstract explanation sometimes helps. Let’s say that you are trying to ask everyone in Mexico “Hello. How are you?” (your source language) Of course, you’ll first need to translate it to Spanish (the native language of the country). That translation would be “Hola. Como estas?” If you know Spanish, … Read more
