Map of Power Systems by Country

Throughout the world, there are a number of different power systems in use. These may vary based on the voltage, frequency, and plugs used. While there are a few standards that are especially common, and most countries use similar systems to their neighbors, there can be surprises. This map is intended to help international travelers (and the curious) sort out which systems are in use where.

The Big Form Factor Guide

One of the most enduring, unchanging aspects of modern computers happens to be the overall system form factor. The form factor may define the size of the motherboard, the size of the power supply, the arrangement of the case, and innumerable other details. This would all be pretty unimportant if there were not so many different form factors, and if new ones were not constantly showing up. But with a basic grasp of each form factor's family tree, you too can make sense of this jumble.

Surviving the Digital Television Transition

On February 17, 2009, the Federal Communications Commision (FCC) has mandated that over-the-air broadcast television switch over from analog transmission to digital transmission. Despite all the press, there is a pretty good chance that this will not affect you in any way. But there is also a chance that your television will go dark forever. So let's sort this out.

The Quick HDMI Guide

The High-Definition Multimedia Interface, almost always abbreviated HDMI, is a video and audio cable standard meant to unify and simplify audio/video cable systems. It is increasingly the de facto standard for A/V equipment, and largely succeeds at its goal of making things simpler. But there are still a few gotchas to watch out for.

10stripe's Perl-Centric Regular Expression Cheat-Sheet

Regular expressions are a compact notation system used for searching through and making changes to strings. Perl happens to have one of the more powerful, complete regular expression engines. Many other languages imitate the behavior of Perl regular expressions, and this cheat-sheet will provide a useful reference for regular expressions in any of those languages.

Rerun: Windows Vista and Driver Signing

Real-life events have prevented an update this week, so enjoy this rerun of an older (and, er, nerdier) update on how Windows Vista handles driver signing and certification. Oh, and a little update to the Big Processor Guide to include Intel's newly-launched Atom processors.

Timeline of Major Web Browsers

In the years since Tim Berners-Lee's original WorldWideWeb application, there have been quite a few web browsers brought to the market. The history and family tree of these browsers can be, in some cases, surprisingly complex. To make that history easier to follow, we have assembled a timeline of some of the major web browsers.

Map of Semiconductor Fabs updated

Now with even more fabs, from even more companies, in even more countries! The map has been updated and expanded, with new companies including International Rectifier, Fairchild, and ON Semiconductor, plus various corrections and adjustments to companies that were already included.

Timeline of Major Microarchitectures

A microarchitecture is, to put it shortly, an implementation of an architecture. In general, knowing the microarchitecture used inside a particular chip tells you a great deal about its guts, which makes this valuable knowledge. So for your convenience, we have compiled all of the post-486 microarchitectures employed by AMD, Intel, and VIA's various x86 products.

Wireless technologies comparison

Wireless technology standards are springing up all over the place, with a broad variety of uses. We thought you might like to have a simple visual comparison of some of the technologies that are most in the news today.

The Quick Transmeta Guide

In January 2000, after more than 4 years of operating in "stealth mode", Transmeta finally announced its first Crusoe products. The little company had enormous courage and a product that amazed the tech press, but unfortunately their products never gained traction in the marketplace. Read on to learn what you should know about this ill-fated processor maker.
