Programming

While going through RxJS, found this amazing article explaining the differences of imperative and declarative programming. In computer science, declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow. Here are some excerpts and learning cliffs to lighten up Saturday quarantine: I draw the line between declarative and non-declarative at whether you can trace the code as it runs. Regex is 100% declarative, as it’s untraceable while the pattern is being executed....

Great talk from Joe Armstrong on how they created Erlang, and how Programming community looked back in the days. Amazing, inspiring, worth watching:

The only reason coders’ computers work better than non-coders’ computers is coders know computers are schizophrenic little children with auto-immune diseases and we don’t beat them when they’re bad. Every single paragraph is amazing. This one cracked me up: “Double you tee eff?” you say, and start hunting for the problem. You discover that one day, some idiot decided that since another idiot decided that 1/0 should equal infinity, they could just use that as a shorthand for “Infinity” when simplifying their code....

Yet another interpretation of “if programming languages were..”. This time it is about programming languages as weapons. Perl is a molotov cocktail, it was probably useful once, but few people use it now. Ruby is a ruby encrusted sword, it is usually only used because of how shiny it is. PHP is a hose, you usually plug one end into a car exhaust, and the other you stick in through a window and then you sit in the car and turn the engine on....

CRAP is short for Change Risk Anti-Patterns – an acronym to protect you from deeply offensive code. Measures the C.R.A.P. (Change Risk Anti-Patterns) score. It is designed to analyze and predict the amount of effort, pain, and time required to maintain an existing body of code. A method with a CRAP score over 30 is considered CRAPpy (i.e., unacceptable, offensive, etc.). C.R.A.P.(m) = comp(m)^2 * (1 – cov(m)/100)^3 + comp(m) Where comp(m) is the cyclomatic complexity of method m, and cov(m) is the test code coverage provided by automated tests....
