Suggestions for locality optimizations (SLO), a cache profiling tool, analyzes runtime reuse paths to find the root causes of poor data locality, and suggests the most promising code optimizations. Refactoring using the hints of the SLO analyzer doubles the average execution speed of several SPEC2000 benchmark programs.

Fast-boot
One can achieve impressive boot-time & performance gains by replacing the BIOS (input/output system) with customized early initialization of the peripherals.
This is relevant to open X86 platforms, such as the Intel Atom processor, that are used in medical, mobile, and automotive applications.
There is an Intel White Paper on how to do this: "Fastboot BIOS - An Investigation of BIOS Speed Enhancement Featuring the Intel Atom Processor (September 2008)" @ http://download.intel.com/design/intarch/papers/320497.pdf

MapleXP (Free) Software
MapleXp is a free (shareware) application that enables one to track multiple projects and categorize and how much time went into each of the tasks involved.
Each project can be divided into a hierarchical structure of tasks, which allows for very precise tracking of working time.

Science and Technology Pipeline
There have been persistent reports on how U.S. is failing to educate sufficient numbers of students for careers in the sciences—science, technology, engineering, and mathematics.
The short answer is that the supply is there - bright and intelligent students - but the corresponding jobs are not there.
See the R&D Magazine Weblog @ http://www.rdmag.com/Blogs-Leaks-in-the-Pipeline/?wnnvz=cIpb87iV1KLyAeAj as well as a related report from the Rutgers University @ http://www.heldrich.rutgers.edu/uploadedFiles/Publications/STEM_Paper_Final.pdf

FlightCaster - the Future?
Is FlightCaster project the future of programming?
FlightCaster uses Hadoop, Clojure, and Amazon Web Services to deliver a predictive system for flight delays (took about 4 months) with 85% success rate predicting long delays. See http://www.sdtimes.com/link/33813

Hadoop
Hadoop is an open-source Java software framework for data-intensive distributed applications. It enables applications to interact with thousands of data nodes.
Hadoop is an implementation of MapReduce which is a programming model for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of intermediate key/value pairs, and a reduce function that merges all intermediate values associated with the same intermediate key.
Programs written in this functional style are automatically parallelized and executed on a large cluster of commodity machines. The run-time system takes care of the details of partitioning the input data, scheduling the program's execution across a set of machines, handling machine failures, and managing the required inter-machine communication. This allows programmers without any experience with parallel and distributed systems to easily utilize the resources of a large distributed system.
Hadoop was created by Doug Cutting, currently with Cloudera.
