How to Build a Computer, Lesson 1: Hardware Basics

How to Build a Computer, Lesson 1: Hardware Basics

The terrifying true story of the garbage that could kill the whole human race — Matter The ship plows on with groaning sails, with a heave and a shove, like a fat man shouldering through a crowd. The motion is surprisingly stop-and-go, without ever really stopping, or quite going. In the open cockpit we’ve just been holding on and talking about flotsam: things that find their way into the vastness of the seas, and float and float, and finally maybe wash ashore. Grimmest to be mentioned so far by my knowledgeable companion—trumping the foot in the boot—is the skeleton in the survival suit. Those are pearls that were his eyes! When we pause the conversation to climb up onto the pitching deck to launch the trawl, I’m keeping Mr. It’s the start of the graveyard watch—2 a.m. to 6—and most everyone’s asleep in their bunks, except the captain, who’s below in the green glow of the nav station plotting our course: a knight’s move, 1,200 miles east to the middle of the South Atlantic, then 800 miles north to Ascension Island. He chucks the trawl into the foam-flecked water.

Donate old gadgets for a good cause video [MUSIC] Goodwill and Dell have teamed up to recycle electronics of any brand at more than 2000 Goodwill locations nationwide. Find one near you at Every item will be carefully sorted to determine whether it can be easily spiffed up and sold at a Goodwill store, dismantled and used for parts, or completely recycled. Need for speed: Why computers stopped getting faster - tech - 23 February 2015 (Image: Pierluigi Longo) Dizzily increasing PC power used to be a given. No longer – speeds stalled a decade ago and only a radical reboot of computing will accelerate things TEN years ago, computers stopped getting faster. That’s true – in a way. You don’t need to be the type who camps outside stores for the latest gizmo to be concerned ...

‘Future Shock’: Orson Welles narrates gloriously schlocky documentary on techno-pessimism, 1972 ‘Future Shock’: Orson Welles narrates gloriously schlocky documentary on techno-pessimism, 1972 I was aware of Alvin Toffler’s Future Shock when I was growing up partly because my dad was sort of in the futurology business himself; he was an analyst at the Hudson Institute under Herman Kahn from the mid-1970s through the late 1980s, which specialized in the project of using trends to generate scenarios about the future—where a certain kind of counterintuitive reasoning usefully pushed back against the excesses of the alarmist left, as represented by Toffler and The Limits to Growth by the Club of Rome. (Kahn was a brilliant man who is mostly forgotten today, but was prominent enough that he was partly the basis for the character of Dr. Strangelove and was also mordantly represented, after a fashion, by the Walter Matthau character “Professor Groeteschele” in the 1964 movie Fail Safe.) Alvin Toffler. Oh no!! Oh, if you want to see Toffler himself he pops up around the 38th minute.

Computer Recycling/IT Asset Disposal (ITAD) in Atlanta GA The dystopian lake filled by the world’s tech lust From where I'm standing, the city-sized Baogang Steel and Rare Earth complex dominates the horizon, its endless cooling towers and chimneys reaching up into grey, washed-out sky. Between it and me, stretching into the distance, lies an artificial lake filled with a black, barely-liquid, toxic sludge. Best of 2015 Our top stories Dozens of pipes line the shore, churning out a torrent of thick, black, chemical waste from the refineries that surround the lake. Welcome to Baotou, the largest industrial city in Inner Mongolia. You may not have heard of Baotou, but the mines and factories here help to keep our modern lives ticking. Element of success Rare earth minerals have played a key role in the transformation and explosive growth of China's world-beating economy over the last few decades. In 1950, before rare earth mining started in earnest, the city had a population of 97,000. After it rains they plough, unstoppable, through roads flooded with water turned black by coal dust.

The depressing truth about e-waste: 10 things to know In 2012, the United Nations reported that in five years, the world's electronic waste would grow by 33% from 49.7 million tons to 65.4 million tons. That's the weight of 200 Empire State Buildings or 11 Great Pyramids of Giza. Considering the lifespan of a cell phone is now only 18 months and a laptop's life span is only around two years, that rapid growth rate isn't surprising. What is surprising, however, is how little the public knows about e-waste and how to properly dispose of electronics. 1. Electronic waste includes all discarded electric or electronic devices with battery power or circuitry or electric elements. 2. Electronic waste is a globalized business, and about 70% to 80% of it is shipped to landfills in many developing nations, where it is sorted and sold for scrap metal or burned to extract materials, which is harmful to people and the surrounding environment. 3. Electronic waste can have many toxic elements inside. 4. 5. 6. 7. 8. 9. 10. Also see

Does Hardware Even Matter Anymore? We are in the midst of a technological revolution that is every bit as profound as the impact of cheap computing power, but it’s subtler and harder to notice. It will ease the way for companies launching and updating digital products, but it presents steep new learning curves that companies will have to master if they are to be successful. What I’m referring to is the migration of functionality from hardware to software. In more and more businesses, physical objects are no longer the primary basis for innovation and differentiation. They come second to innovations in computer code. Managers are well aware that Moore’s Law, the idea that the number of transistors on a practical-sized chip doubles every 18 months, has brought us a bounty of cheap computing power, leading to smartphones, tablets, fitness trackers, cloud-based services like Facebook and Uber, and on and on. Consider, for example, how we convert and control electrical power. There are important implications for companies.
