Computer Scientist's Trivia
Common latency numbers, binary notation tricks, some floating point hacks, etc. More distilled than encyclopedic.

Bell Labs and CSP Threads
This page is a slice of the history of concurrent programming, focusing on one particular lineage of Hoare's language of communicating sequential processes (CSP) [1] [1a]. Concurrent programming in this style is interesting for reasons not of efficiency but of clarity. That is, it is a widespread mistake to think only of concurrent programming as a means to increase performance, e.g., to overlap disk I/O requests, to reduce latency by prefetching results to expected queries, or to take advantage of multiple processors. Such advantages are important but not relevant to this discussion. After all, they can be realized in other styles, such as asynchronous event-driven programming. Instead, we are interested in concurrent programming because it provides a natural abstraction that can make some programs much simpler.

Efficient data transfer through zero copy
NIO performance tip: use FileChannel.transferTo() to reduce unnecessary copying between kernel and application buffers. With newer operating systems, it may actually avoid copying altogether.

Erik Engbrecht's Blog: What does I/O bound really mean?
More WideFinder commentary: I/O from the programmer's perspective is, or at least should be [] “everything that happens between when my program requests some data and when it receives it.”

STEPS Toward The Reinvention of Programming (Viewpoints Research Institute)
Alan Kay's ocean-boiling project completed its first year - this is a report of the work done so far. I've only briefly skimmed the paper, but the ideas described look extremely provocative and insightful.

Improved Means for Achieving Deteriorated Ends / The State of State
Tim Sweeney (Unreal architect and occasional LtU participant) talks about how STM is more appropriate for large mutable-state-heavy apps and Erlang-like message passing is better for distributed computation where latency is a big deal.
