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!

If you haven't heard of it, this island has a population that the world has collectively decided to leave alone, mostly because they have proven, on multiple occasions, that they absolutely do not want visitors. Like, arrow-to-death anyone attempting to land or even visit near their shores.

This probably cannot go on forever... but maybe, it could. Essentially, we are already implementing a 'Prime Directive' of sorts here. Would the 23rd, 24th, ... centuries in Star Trek canon still have this little island on Earth, isolated from not just from Earth's own unified Federation society, but from the greater Federation races? What steps would the Federation and Earth take to maintain their isolation and the ecosystem on which they depend?

Would make for an interesting episode, or at least a cool side-note reference in one :)

For Funtoo users, simply sudo emerge dev-lang/apl :)

Normally I avoid linking to the old sh$thole here ('cuz you know, f*ck u/Spez), but this is an exception.

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

Best book for learning the ins and outs of MIDI I've ever encountered. Relatively obscure, but an invaluable reference book for anyone wanting to dig into the details of how MIDI works.
