What Is Green Information Technology?

What Is Green Information Technology?

There is no doubt that today’s environment is significantly different from the environment of 20 years ago. There are a lot more cars, industries and pollution from all kinds of sources. With developing countries consuming more than developed countries, it is becoming an unsustainable scenario where millions of tons of waste is generated on a continuous basis. Amid all this, there is also the problem of information technology.

As IT grew, people and organizations began to buy more computers, devices, servers and other peripherals, leading to more electronic waste. Some of this waste is very hazardous and polluting to the environment. Moreover, computer peripherals tend to use a lot of energy and companies that make profits from the IT sector have a unique responsibility towards their environment.

With this in mind, Green Information Technology is the practice of environmentally sustainable computing. Green IT, as a philosophy, came into being in 1992 when the Energy Star labeling system was unveiled by the U.S. Environmental Protection Agency. It is a labeling system that helps companies to reduce greenhouse emissions and save money as well. It does this by identifying superior and green products that reduce greenhouse emissions & energy consumptions.

With this in mind, we can kind of gather where the philosophy of Green IT comes from. Now, in order to understand green IT in today’s context, let us take a look at some of the problems that are pulling us down as a society.

1. Electronic waste 
Today, companies generate a lot of electronic waste. This includes computers, laptops, batteries, chips, smartphones, silicon and a host of other waste products. All this pollute our environment greatly. Green IT involves safe disposal of electronic waste and dealing with companies who will also engage in safe disposal of their electronic waste. Adequate waste disposal methods need to be put in place in all IT departments and this actually needs to be a part of IT governance.

2. Increased energy consumption
The more we consume energy, the scarcer coal, water and other products will be. Nuclear technology has its own risks. The best we can do is to reduce energy consumption. It order to do this, companies can adopt cloud computing, instead of buying their own personal infrastructure.
Shared platforms and infrastructure help companies to reduce their greenhouse emissions & energy consumptions. It becomes our moral responsibility to choose products and services, which work towards reducing energy consumption. Cloud computing will definitely be one of the preferred options because of this.

3. Culture of replacing products, instead of repairing
A number of companies continue to replace their devices and peripherals even when it is not required. These older devices can easily be fixed and used for a few more years. Companies need to actively encourage repairing devices rather than replacing them. This is an important part of green IT. When we repair existing products, waste generated by our companies will be lesser.

4. Using low quality products 
Low quality products consume more energy and emit more greenhouse gases. They might also be manufactured with unsafe and toxic materials, which do not degrade biologically. In order to avoid this, we will need to invest in high-quality and energy-efficient products, which are green and environmentally friendly.
They might prove to be expensive in the beginning but you will save a lot of money in the long term. Low quality products do not go through the standard testing protocols and some of them fail emission level tests, hazardous materials test and other such tests miserably. They are also known to drain electricity more than high quality products.

Looking ahead
Green IT is only going to grow bigger. As global warming is becoming more important to tackle, we all will need to focus on green IT. This begins with doing business with companies that are green and sustainable. It becomes our responsibility to push green philosophy for the sake of environment.

It becomes a moral responsibility not only for companies but also for end users and clients. Unless you go green, people might hesitate to conduct business with you. In the near future, we can see a growing awareness about environment-friendly behaviors and people will likely prefer to use products & services from companies that stand up to their green ideals.

6 things to love - and hate - about the iPhone 6

Let's just start with this: The iPhone 6 is the best smartphone ever made.
But it's not perfect. Like any smartphone, there are some things about the iPhone 6 that will drive you batty.
First here's what you'll love about the iphone 6
1) the rounded edges. The iphone 6 feel really. really good in your hand.

It's insanely thin and light, and there are hardly any square or jagged edges on the device. The vibrate toggle switch is the big exception -- it nicked me a couple of times when I was pulling the iPhone out of my pocket.
The curves give the iPhone 6 a less distinctive look than some of its predecessors and other smartphones on the market. But what the iPhone 6 sacrifices in appearance it makes up in usability. I don't want to put the iPhone 6 down when I'm holding it.
2) The camera. Ironically, the ugliest part of the iPhone 6 helps deliver its most beautiful features.

The iPhone 6's camera juts out of the phone's back by about a millimeter, and the obsessive part of me kept wanting to pop it back in. But whatever Apple got out of that millimeter was worth it.
How much does your iPhone really cost?

Photos are clear just about every time. It performs masterfully in weird lighting situations, such as when the subject is in a shadow but the sun is shining brightly. It takes photos remarkably quickly and -- most importantly for photo-taking dullards like me -- without any fuss. And the front-facing camera also takes surprisingly good photos for the selfie-taking types.
The time-lapse and slo-mo video functions seemed more gimmicky than practical to me, but some people might find them useful -- or at least fun.
3) The screen. The iPhone 6's display is gorgeous. It's noticeably sharp, and the iPhone 6's display even looks great when you're not looking at the screen straight on.

That's helpful, say, when you're watching a video with friends or showing photos to your family.

4) TouchID. There is no shortage of complaints about the iPhone's fingerprint sensor malfunctioning, but I found it to be wonderfully convenient and accurate. It makes signing into your phone, downloading apps and buying music a breeze.

So if it works for the simple stuff, Apple Pay is going to be a cinch. Paying for stuff with your iPhone 6 supposedly will be as easy as holding your phone up to a payment terminal while touching the Touch id sensor. We'll see next month when Apple Pay launches -- but it sounds promising.

And here's what you'll hate about the iPhone 6.
5) iCloud. What an absolute mess.
iphone 6 icloud
When setting up my iPhone 6, one of the umpteen prompts asked me if I wanted to "upgrade to iCloud Drive." For about 12 hours, when I went to my iCloud settings, iCloud Drive indicated that it was "upgrading" with a pinwheel of death next to it. And once it finally decided to finish upgrading, it didn't impress me. I uploaded a photo and a document via iCloud.com, and I have absolutely no idea how to view those on my iPhone. There isn't even an iCloud Drive app.
Meanwhile, iCloud says it will back up my photos via Photo Stream, but there's no obvious way to manage that -- it doesn't even exist on iCloud.com. What if I want to store photos on iCloud but not on my phone to save precious storage?

6) iOS 8. There are some really nice new features in iOS 8, including the amazing Spotlight universal search feature, text notifications that let you respond without opening iMessage, and all the brilliant camera software. That's on top of excellent existing iOS features, such as the brilliant Control Center quick tasks launcher, Facebook integration and of course FaceTime.

But there's plenty to hate about iOS 8, too. Setting up an iPhone is an unacceptably lengthy experience with way too many questions, options and notifications. Siri still doesn't do anything particularly worthwhile. Apple annoyingly added unnecessary steps for accessing and clearing notifications. And none of the "widgets" in the notification screen that I tested were particularly useful.

There's also a lot of Apple bloatware, including compass (really, Apple?), "tips," maps and Passbook. Others are redundant, including the contacts, FaceTime and camera apps that you can access in other places. But you can't delete or hide those apps -- the only way to clear them off your screen is to put them in a folder labeled "crap."
So here's the bottom line: The iPhone 6 is a gorgeous, incredibly well-designed smartphone with a world-beating camera and some neat tricks. But Apple's software gets in the way of the iPhone 6 being a perfect smartphone.

If you paid an extra $100 or even $200 for a smartphone with more storage, you got ripped off.

We quickly fill up those gigabytes on our smartphones with photos, videos, apps, music and all sorts of other cherished personal files and mementos. Constantly deleting those files is a pain, so splurging on extra storage is a bullet many of us have chosen to bite.
But smartphone makers pay as little as a sixth of what they charge you for those extra gigabytes of storage. And that applies to all of the four largest U.S. smartphone makers -- Apple (AAPL, Tech30), Samsung, LG or Motorola.
The flash storage drives installed in the iPhone 6 cost Apple just $7.55 per 16 GB, according to TechInsights, a patent consultant that performs gadget tear-downs. The 32 GB of storage included the Galaxy S6 costs Samsung $14.50.
That means the difference between a base model 16 GB iPhone 6 and a top-of-the-line 128 GB iPhone 6 costs Apple about $53. It costs you $200.

Apple charges you as much as $100 for just 48 extra GB of storage.
It's even worse for a Galaxy S6. The difference between the base 32 GB model and the best 128 GB model costs Samsung $44. But Samsung charges you $200 more.
None of the four smartphone makers commented for this article.


How to beat the storage cheats
Luckily, there are ways to avoid overpaying for storage.
1) Back up your photos. You can use Google's wonderful new Photos app to store all of your photos and videos. Google (GOOGL, Tech30)will give you free, unlimited storage, albeit in a somewhat smaller file size. If you're not planning on blowing up your photos, you'll be fine.
2) Stream your music. Instead of storing your personal music library on your phone, you can stream it. Google Play Music Manager and Amazon (AMZN, Tech30) Cloud Drive allow you to upload your entire music library to the cloud, and stream it to your phone using the Google Play Music and Amazon Music apps. You can also stream music you don't own with free services, such as Spotify or Pandora. (P)
3) Use cloud drives. You can use Drop Box, Google Drive, Microsoft (MSFT, Tech30) One Drive or Apple iCloud to manage your files in the cloud.
4) Clean your phone. And if you use apps such as DU Speed booster for Android or Phone Clean for iPhones, you can clear out unnecessary files that accumulate on your phone.
5) Buy a phone with a micro SD slot. Along with removable batteries, micro SD expandable storage slots in phones have largely gone the way of the dinosaur. But there are a few remaining holdouts, including the excellent LG G4. You can buy a 128 GB micro SD card on Amazon for about $60. It's not as fast or robust as your phone's internal storage, but it'll do the trick nicely for photos and videos.
So if overpaying for storage isn't your thing, you've got a way to fight back.

The Swimming Secrets of Duck Feet

Introduction

Water birds use their feet to swim through the water, often as a way to get food. Penguins need to dive and swim quickly through the water to chase and catch small fish as prey. Ducks swim to eat from the bottom of ponds, lakes, and streams. Each type of swimming bird has a unique adaptation for locomotion through the water.
How do ducks swim? According to the National History Museum: "Birds with webbed feet can paddle through the water and walk on mud. As a duck pushes its feet back, the web spreads out to provide more surface to thrust the water. Then, as the duck draws its foot forward and brings the toes together, the web folds up so there is less resistance to the water" (NHM, 2006). This resistance is in the form of friction, and is an important force in hydrodynamics and locomotion.


Here is a picture of two duck feet showing the webbing between the toes. 

There are many different kinds of water birds, each with adaptations for swimming through the water. Ducks, geese, and pelicans have webbing between their toes. Other water birds, like grebes have flattened, lobed toes that help with diving and swimming. In this experiment you will use swim fins to make three sets of bird feet: one from a non-swimmer, one from a grebe, and one from a duck. Which adaptations will help a swimmer swim the fastest?
