The Wolfram Alpha Web site lets you dig into facts, figures, math, calculus, statistics, and other "computational knowledge" at a level you've never had before.  Give it a try and you're sure to bookmark it in your browser.

Linear Technology had developed a technique that measures the impedance of power-supply connections and creates a proportional feedback signal that lets a switching regulator circuit overcome voltage drops between the supply and its load. The technique uses Virtual Remote Sensing, which the company uses in its LT 4180 chip.

You can manage large software projects, but you must learn how to apply a new "management" technique such as the Team Software Process (TSP) developed at Carniege-Mellon University's Software Engineering Institute. Learn more about it and how to use it.

The TinyLogic family of single-element logic devices gives engineers and designers a way around the need for that elusive "extra" gate, inverter, or flip flop they must have to cram a low-power design on a board. Instead of using a quad NAND-gate of hex-inverter package, they can add one inverter, gate, or other common logic function.

While at the Embedded Systems Conference two handy tools caught my eye. First, the Mobidapter, an SD-to-USB adapter from Saelig and second the Micro Computer Control i2cStick that gives you a connection between a USB port and an I2C bus.
