| Re: Vector 23, N°4 Online now at http://www.vector.org.uk/ — Parallel thinking. The repeal of Moore’s Law has left manufacturers unable to push processors any faster. So they push more of them into machines. But pulling more speed out is hard work. Can array languages help? David Liebtag introduces APL2’s parallel-processing operators. — First experiences with Unicode in Dyalog 12. Adrian Smith tries migrating Dyalog programs to Version 12 Unicode and winds up with less than he started with. Less code, that is. But he’s not complaining… — If you think J is complex try j. In his 50th J-ottings column Norman Thomson finds a few simple diagrams clarify how J handles complex numbers.
