Whether you are an old hand at APL, or someone just discovering the language, having the symbols in the standard layout right there on your keyboard is a great help... dedicated APL keyboards are pretty expensive, so consider these stickers that let one adapt any standard desktop or laptop keyboard!

GNU APL is easy to build on your own Linux machine, though the steps aren't detailed on the website. --- Benefits of building yourself locally: - One can customize how many cores GNU APL has access to - Customizing optional extensions like PNG image, SQLite, GTK support etc. - Having the latest bugfixes --- 1. Obtain the latest source - mkdir apl-build - svn checkout http://svn.savannah.gnu.org/svn/apl/trunk 2. Configure using autotools - cd trunk - make clean - ./configure CORE_COUNT_WANTED=3 RATIONAL_NUMBERS_WANTED=yes --with-ctrld_del Use ./configure --help to see other options, adjust to taste 3. Build and install - make -j && sudo make install 4. Set up your default workspace - cd ~ - mkdir -p GNUAPL/workspaces ---
