The term "referential transparency" comes from analytical philosophy, the branch of philosophy that analyzes natural language constructs, statements and arguments based on the methods of logic and mathematics. In other words, it is the closest subject outside computer science to what we call programming language semantics. The philosopher Willard Quine was responsible for initiating the concept of
As ever, the terminology people use is not entirely consistent. There's a variety of inspired-by-monads-but-strictly-speaking-isn't-quite notions. The term "indexed monad" is one of a number (including "monadish" and "parameterised monad" (Atkey's name for them)) of terms used to characterize one such notion. (Another such notion, if you're interested, is Katsumata's "parametric effect monad", ind
I've asked before about how to squash the first two commits in a git repository. While the solutions are rather interesting and not really as mind-warping as some other things in git, they're still a bit of the proverbial bag of hurt if you need to repeat the procedure many times along the development of your project. So, I'd rather go through pain only once, and then be able to forever use the st
I start to read JavaScript Patterns, some codes confused me. var global = (function () { return this || (1, eval)('this'); }()); Here are my questions: Q1: (1, eval) === eval? Why and how does it work? Q2: Why not just var global = (function () { return this || eval('this'); }()); or var global = (function () { return this; }());
I have a Git repository which contains a number of subdirectories. Now I have found that one of the subdirectories is unrelated to the other and should be detached to a separate repository. How can I do this while keeping the history of the files within the subdirectory? I guess I could make a clone and remove the unwanted parts of each clone, but I suppose this would give me the complete tree whe
Java generics are indeed implemented by type erasure, so there is no type information in the bytecode. For example, let's take a look two classes which declare a List field, one in generic and the other in non-generic form: class NonGeneric { List list; } And, class Generic { List<String> list; } In both cases, the resulting bytecode is the following: Code: Stack=3, Locals=1, Args_size=1 0: aload_
