  Clojure & Java Interop

About a year ago I got a phone call asking if I wanted to join another team at DRW. The team supports a (primarily) Java application, but the performance requirements would also allow it to be written in a higher level language. I'd been writing Clojure (basically) full-time at that point - so my response was simple: I'd love to join, but I'm going to want to do future development using Clojure. A year later we still have plenty of Java, but the vast majority of the new code I add is Cloj...

Whiteboard questions generally don't include much in the way of overall design, and they're typically limited to simple algo...

  FTP Must Die

The File Transfer Protocol (FTP) is specified in RFC 959, published in October 1985. The attempt in this specification is to satisfy the diverse needs of users of maxi-hosts, mini-hosts, personal workstations, and TACs, with a simple, and easily implemented protocol design.That's from the introduction. Does anyone here know what a TAC is? I don't. I had to look it up, since the acronym wasn't even expanded in the RFC. It took three tries in Google, and I finally found it in some obscur...
