I returned to Haskell for my personal projects from Erlang for the simple virtue of Haskell’s amazing type system. Erlang gives you a ton of tools to handle when things go wrong. Haskell gives you tools to keep you from going wrong in the first place. When working in a language with a strong type … Read more
It looks at the file time-stamp – simple as that. If a dependency is newer that the target, the target is rebuilt.
BASIC 10 PRINT “Sara is the best” 20 GOTO 10 Update: when I was 12, my cousin (he was 14) brought Turbo Pascal 7.0 and installed it in my computer. He programmed a tic tac toe game from scratch (in BGI mode, for those who know). I watched/observed step by step how a program evolves … Read more
A homebrew Forth runtime can be implemented in very little memory indeed. I know someone who made one on a Cosmac in the 1970s. The core runtime was just 30 bytes.
Orthogonality implies that two things are unrelated. It comes from mathematics where it means perpendicular. In common usage it can mean two decisions are unrelated or that one subject is irrelevant when considering another subject. As used here, orthogonal means that one concept doesn’t either imply or exclude the other. The two concepts object oriented … Read more

Directly from Oracle Docs Package names are written in all lower case to avoid conflict with the names of classes or interfaces.
‘Expressive’ means that it’s easy to write code that’s easy to understand, both for the compiler and for a human reader. Two factors that make for expressiveness: intuitively readable constructs lack of boilerplate code Compare this expressive Groovy, with the less expressive Java eqivalent: 3.times { println ‘Hip hip hooray’ } vs for(int i=0; i<3; … Read more
The name “C sharp” was inspired from musical notation where a sharp indicates that the written note should be made a half-step higher in pitch.[6] This is similar to the language name of C++, where “++” indicates that a variable should be incremented by 1. The sharp symbol also resembles a ligature of four “+” … Read more
There is a difference between initialization and assignment. What you want to do is not initialization, but assignment. But such assignment to array is not possible in C++. Here is what you can do: #include <algorithm> int array [] = {1,3,34,5,6}; int newarr [] = {34,2,4,5,6}; std::copy(newarr, newarr + 5, array); However, in C++0x, you … Read more
