C/Golang/Lua/Vala/SBCL/Ada/Pascal and an embedded datastore like bdb!
Why in my day we used to write little apps with C and bdb that used less than 5mb of memory! (Sqlite didn't exist yo.)

Ruby users are quiche eaters anyway. Real programmers write their code in Fortran and persist to a hierarchical database on a mainframe.
You think real programmers need needles.
