#BASIC#ProgrammingLanguages#ComputerScience: "Sixty years ago, on May 1, 1964, at 4 am in the morning, a quiet revolution in computing began at Dartmouth College. That's when mathematicians John G. Kemeny and Thomas E. Kurtz successfully ran the first program written in their newly developed BASIC (Beginner's All-Purpose Symbolic Instruction Code) programming language on the college's General Electric GE-225 mainframe.
Little did they know that their creation would go on to democratize computing and inspire generations of programmers over the next six decades."
A weird thing about being 50 is that there are programming languages that I've used regularly for longer than some of the software developers I work with have been alive. I first wrote BASIC code in the 1980s. The first time I wrote an expression evaluator--a fairly standard programming puzzle or homework--was in 1990. I wrote it in Pascal for an undergraduate homework assignment. I first wrote perl in the early 1990s, when it was still perl 4.036 (5.38.2 now). I first wrote java in 1995-ish, when it was still java 1.0 (1.21 now). I first wrote scala, which I still use for most things today, in 2013-ish, when it was still scala 2.8 (3.4.0 now). At various times I've been "fluent" in 8086 assembly, BASIC, C, Pascal, perl, python, java, scala; and passable in LISP/Scheme, Prolog, old school Mathematica, (early days) Objective C, matlab/octave, and R. I've written a few lines of Fortran and more than a few lines of COBOL that I ran in a production system once. I could probably write a bit of Haskell if pressed but for some reason I really dislike its syntax so I've never been enthusiastic about learning it well. I've experimented with Clean, Flix, Curry, Unison, Factor, and Joy and learned bits and pieces of each of those. I'm trying to decide whether I should try learning Idris, Agda, and/or Lean. I'm pretty sure I'm forgetting a few languages. Bit of 6502 assembly long ago. Bit of Unix/Linux shell scripting languages (old enough to have lived and breathed tcsh before switching to bash; I use fish now mostly).
When I say passable: in graduate school I wrote a Prolog interpreter in java (including parsing source code or REPL input), within which I could run the classic examples like append or (very simple) symbolic differentiation/integration. As an undergraduate I wrote a Mathematica program to solve the word recognition problem for context-free formal languages. But I'd need some study time to be able to write these languages again.
I don't know what the hell prompted me to reminisce about programming languages. I hope it doesn't come off as a humblebrag but rather like old guy spinning yarns. I think I've been through so many because I'm never quite happy with any one of them and because I've had a varied career that started when I was pretty young.
I guess I'm also half hoping to find people on here who have similar interests so I'm going to riddle this post with hashtags:
CakeML is a functional programming language and an ecosystem of proofs and tools built around the language. The ecosystem includes a proven-correct compiler that can bootstrap itself.
Been having fun with #gleamlang , made more than a hundred lines of code with it. It's really refreshing having a language that compiles fast and takes barely any memory and cpu to run.
Not having to care about the build tool too much, hundreds of compiler flags, language versions, compiler plugins, formatting plugins, or any of the usual things that fill the brain I'm used to in #scala is a huge breath of fresh air.
For real, whoever is saying that F# or OCaml require a PhD in Math or are languages just for math, science, and academic stuff is completely lying to you, it is no harder than learning JavaScript/python or any other language out there.
I learned #FunctionalProgramming to escape the imperative programming languages, which in turn got me interested into #Compilers and #ProgrammingLanguages. Turns out, most of the real-world compilers are written in C and C++, so here I am back at square one.
After years of avoiding it for decades, I taught myself #Cpp in the last couple of weeks. So anyway, does anyone want me to write a series of #blog posts about making a #Lisp interpreter (https://github.com/kanaka/mal) in C++?
I've been learning Lua this week for no reason (LÖVE), and I don't know why devs joke about "arrays starting at 1" when this shit is more hilarious IMO
