  Power Distribution Units (PDUs) – you mean power strips, right? That's what I thought when I was first introduced to this product. Boy oh boy was I wrong! Yes, the PDUs that are manufactured to be sold to the owners and operators of data centers do bear some similarities to the simple power strips that we all use at home. But we are really talking about two very different products here.
  
  What You'll Find Inside:
  POWER DISTRIBUTION UNITS (PDU): WHAT ARE THEY?
  WHY FUSES ARE BAD AND WHAT TO DO ABOUT IT
  WHAT THE WORLD OF FORMULA 1 AUTO RACING CAN TEACH DATA CENTER OPERATORS
  WHY DATA CENTER OPERATORS ARE SWITCHING TO USING HY-MAG
  
  How much money do you think that a data center operator has invested in just one of the racks of computers that sits in his or her data center? There is the cost of the rack, of course, but then there's the cost of each of the servers that has been plugged into that rack, the networking gear, and the power distribution system. Not to mention the overhead of cooling and power distribution to the rack. Very quickly the value of a single rack can reach US$500,000.
  
  Clearly it's in the best interests of the data center operator to know exactly what is going on with their investment. Questions that need to be answered include how much power is being used, if there is currently a fire, are there any hot spots, and whether there are any liquids in the area.
  
  The problem with today's modern data center is that all too often the answers to these questions are not available unless staff are sent out on to the data center floor with tools to make measurements. This means that a lot could go on when nobody was looking.
  
  Today's modern PDUs do so much more than just simply deliver power to the computers that have been plugged into a rack. They provide the "eyes and ears" that data center operators need in order to determine what is happening with their racks. Modern PDUs can support multiple types of sensors that can be used to piggy-back environmental information along with power usage information back to a central control system.
  
  Sophisticated Data Center Infrastructure Management (DCIM) software applications promise to be able to monitor all aspects of a data center. However, they are expensive and require an additional investment to both install and then maintain. The use of PDUs to collect needed data center status information provides a simple and low cost way to automate the monitoring of a modern data center.
  
  This book has been written to provide you with the information that you'll need in order to compare and contrast different types of PDUs. These sophisticated tools can be difficult to tell apart. This book will look at the features that you really needs and explain how you would use then in the real-world environment of a modern data center.
  
  It is my hope that after having read this book, you'll have the knowledge that you'll need to go out and select the type of PDU that best meets the needs of your business. Once you've done this, you can then implement a solution that will allow you to always know what is going on in your data center.

  Rachel Kaplan describes the Urban Homesteading Movement as “…not only a food movement but also a movement of people who are about conservation of energy, water, and waste. It is a movement of learning to live with less impact on the earth, with a greater sense of what it means to be part of the place where we live, and to be thinking ecologically.”

  “A huge, beautiful compendium of 600 frogs from around the world, from the famed poison-arrow variety on up to the intriguingly named plaintive rain frog.” —Wired 
   
  With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin’s Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. 
   
  The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature’s most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size—including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. 
   
  As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world. 
   
  “If you are a serious (and I mean serious) fan of the frog, you are in for a real treat.” —Boing Boing

  Ultimate Anatomy Study Guide -...

  If you are like 99% of students, you are probably learning by rote. In other words, you become a robot - mechanically repeating the information that needs to be learned. Studying this way is extremely easy, especially with a subject like anatomy, which has rote learning written all over it. More than likely, understanding the subject is quite easy for you. And that's great! But the question is, how long will you retain the information you have learned using this technique? Do you feel that after two or three days you forget all the important stuff? Well, join the club; we have been there (and some of us still are) and we understand the feeling.
          
          Most of the students we know follow a rather straightforward method of learning: they open their anatomy book, start reading the page, take some notes, revise a bit and hope for the best. Do you follow a similar approach? It is definitely not the worst strategy, but you’ll shed a lot of blood, sweat, and tears... 
          
          The good news is that there are a lot of alternatives to this strategy and we are here to show you some of them. But we’ll be honest from the very beginning; there are no magic tricks that will enable you to learn everything automatically. There is no “one simple rule” to remember everything. Whoever told you that has never studied anatomy!

  Cretaceous Period The: The...

  Early societies were aware of fossils, but they had no conception of just how old they were; the ancient Chinese, for example, classified many fossils as the bones of dragons. It wasn’t until 1822 that a new word was coined, “paleontology,” and it was used to describe the emerging science of using the fossil record to understand what the world was like in the far distant past. 
  	Gradually, a better understanding emerged of the different periods through which the Earth had passed and a realization that for hundreds of millions of years, it wasn’t humans but a very different species that ruled the Earth. By the 1840s, paleontologists began to give names to different eras in an attempt to describe this history and to further subdivide eras into periods. Many of those period names are now very familiar, Jurassic and Triassic, for example, but there was an 80-million-year period in which the planet changed completely: the Cretaceous. This period began with dinosaurs as the dominant species on Earth, with mammals restricted to a few small rodents cowering in holes. By its end, the continents had begun to resemble a modern map, the dinosaurs had all but disappeared, and new species arose to dominance. 
  The Cretaceous Period: The History and Legacy of the Geologic Era that Ended with the Extinction of Dinosaurs looks at the development of the era, the extinction events that preceded it and ended it, and the aftermath.
