This is a home for my implementations of the problems at http://projecteuler.net.

I first coded the problems in Perl. I then wrote them in 
C, C++, Java, Python, Forth, ARM assembly language, Racket, Erlang, ...

If you want to run and time all of the code, on debian you can do ..

$ sudo apt install time cmake gcc flex bzip2 git erlang racket build-essential gcc g++ gforth python3 ocaml-core ocamlbuild opam liblist-moreutils-perl libchart-gnuplot-perl libcgi-pm-perl perl6 golang cargo rustc tcl ruby node-typescript elixir openjdk-11-jdk-headless

$ wget http://download.savannah.gnu.org/releases/proccpuinfo/libproccpuinfo-0.0.8.tar.bz2

$ tar jxvf libproccpuinfo-0.0.8.tar.bz2

$ cd libproccpuinfo-0.0.8

$ cmake -D CMAKE_INSTALL_PREFIX=/usr .

$ make

$ make test

$ sudo make install

$ sudo perl -MCPAN -e 'install Devel::CheckLib'

$ sudo perl -MCPAN -e "CPAN::Shell->notest(qw/install Linux::Proc::Cpuinfo/)"

$ opam init

$ opam install core

$ cd scripts

$ ./timeall 
This should run all of the code and put the results into ../data

$ PERL5LIB=. perl html_table.pl 
This should read the data files (checking that all computed values match) and then write ../output/project_euler_timings_$(hostname).html
