Ask anyone about why Bitcoin has suddenly risen to prominence and they may offer one of a number of theories. Perhaps it'll be the one about Cypriots smuggling money out of their country, or the promise of a digital gold rush, or perhaps the tale of a disruptive new economy created by a person who may not even exist. Either way, if you'd like to untangle the myths, half-truths and labored economic newspeak behind the world that is Bitcoin, why not join us after the break?

Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com.
As you're hopefully aware, this is a gadget blog. As a result, we're innately biased towards stuff that's new and preferably fandangled. More cores, more pixels, more lenses; just give it here and make us happy. The risk of this type of technological greed is that we don't make full use of what we already have, and nothing illustrates that better than the Graphics Processing Unit. Whether it sits in our desktops, laptops, tablets or phones, the GPU is cruelly limited by its history -- its long-established reputation as a dumb, muscular component that takes instructions from the main processor and translates them into pixels for us to gawp at.
But what if the GPUs in our devices had some buried genius -- abilities that, if only we could tap into them, would yield hyper-realistic experiences and better all-round performance from affordable hardware? Well, the thing is, this hidden potential actually exists. We've been covering it since at least 2008 and, even though it still hasn't generated enough fuss to become truly famous, the semiconductor industry is making more noise about it now than ever before.
So please, join us after the break as we endeavor to explain why the trend known as "GPU compute," aka "general purpose GPU (GPGPU)," or simply "not patronizing your graphics processor," is still exciting despite having let us down in the past. We'll try to show why it's worth learning a few related concepts and terms to help provide a glossary for future coverage; and why, on the whole, your graphics chip is less Hasselhoff and more Hoffman than you may have imagined.

Digital audio. There's a very good chance that you've enjoyed some today. It's one of the more universal aspects of technology. In fact, perhaps the more relevant question would be, when was the last time you listened to an analog format? The truth, for many, will be quite some time ago -- vinyl purists and the odd cassette fanatic aside. Yet, despite its ubiquity, there's a lot of misunderstanding and confusion about digital audio. Some believe it'll never match analog for true fidelity, some assert quite the opposite. Many lament the lack of a tactile format, while others love the portability that comes with zeros and ones.
In this installment of Primed, we take a look at the history of digital sound, as well as provide an introduction to some of its key components, with the view to helping us understand it better. Wondering what bitrate to encode your MP3s at? Or whether you should choose a 96 or 44.1KHz sample rate? We thought as much. By the time we're through, these questions should no longer lay heavy on your mind, and you can enjoy that latest Knife Party, or Britney track as much as its bit depth allows. What's bit depth you say? Well, read on to find out...

Welcome to one of the most unnecessarily complicated questions in the world of silicon-controlled gadgets: should a savvy customer care about the underlying nature of the processor in their next purchase? Theoretically at least, the answer is obvious. Whether it's a CPU, graphics card, smartphone or tricorder, it'll always receive the Holy Grail combo of greater performance and reduced power consumption if it's built around a chip with a smaller fabrication process. That's because, as transistors get tinier and more tightly packed, electrons don't have to travel so far when moving between them -- saving both time and energy. In other words, a phone with a 28-nanometer (nm) processor ought to be fundamentally superior to one with a 45nm chip, and a PC running on silicon with features etched at 22nm should deliver more performance-per-watt than a 32nm rival.
But if that's true, isn't it equally sensible to focus on the end results? Instead of getting bogged down in semiconductor theory, we may as well let Moore's Law churn away in the background while we judge products based on their overall user experience. Wouldn't that make for an easier life? Well, maybe, but whichever way you look at it, it's hard to stop this subject descending into pure philosophy, on a par with other yawnsome puzzles like whether meat-eaters should visit an abattoir at least once, or whether it's better to medicate the ailment or the person. Bearing that in mind, we're going to look at how some key players in the silicon industry treat this topic, and we'll try to deliver some practical, offal-free information in the process.
