Tom Duff on Duff's device (1988)
I normally do not read comp.lang.c, but Jim McKie told me that `` Duff's device '' had come up in comp.lang.c again. I have lost the version that was sent to netnews in May 1984, but I have reproduced below the note in which I originally proposed the device. (If anybody has a copy of the netnews version, I would…

JEP 454: Foreign Function and Memory API
Introduce an API by which Java programs can interoperate with code and data outside of the Java runtime. By efficiently invoking foreign functions (i.e., code outside the JVM), and by safely accessing foreign memory (i.e., memory not managed by the JVM), the API enables Java programs to call native libraries and…

Clojure - Getting Started
Clojure is a dynamic development environment where you interact with your program while you write it, growing and adding to it while it’s running. To work with Clojure you need an editor that supports evaluation in source files and structural editing (working with nested forms in addition to character editing).

Taking PHP Seriously
Slack uses PHP for most of its server-side application logic, which is an unusual choice these days. Why did we choose to build a new project in this language? Should you?
