...Technology...

Twitter says goodbye to the favorites and gives welcome LIKE


Twitter announced Tuesday it will eliminate "favorites" platform, a function that will be called "likes" and to be represented by a heart instead of a star.
The aim of this formal change, which follows the symbolic wake of Facebook and Instagram, is to make the most simple and intuitive interaction, especially for new users: Twitter sees the heart and the expression "like" are more universal, descriptive and understandable that the star and "favorite" word.
"We want Twitter is an easy and rewarding to-use and know that sometimes, the star could be confusing, especially for newcomers. Surely you like a lot of things, but all can not be favorites," said the in a statement.
The objectives of the CEO of Twitter, Jack Dorsey, the figure easier to use platform: to date, investors have been criticizing that the service is not very appetizing and quite confusing for new users.
There are four ways to interact with another user on the network of "microblogging": writing a tweet, "retuiteándolo", putting a direct message (private communication) or marking a tweet as a favorite, an action that is performed by pressing a button star shape.
Basic earnings show that the favorite is liked a tweet, but it is also a way to select to access it later. The functions of the new "likes", predictably, will not be very different, but Twitter defend the symbol of the heart "can transmit a wider range of emotions."
The shift to "like", which takes effect Tuesday, will also be introduced in the implementation of short videos as Vine.Periscope, also owned by Twitter, already it has the symbols of hearts.

Imapacts of the technology in outdoor recreation and adventure

Technology plays an increasingly influential and important role in outdoor recreation and adventure. The last 10 years, in particular, have seen a virtual explosion of technological developments in the outdoors, ranging from clothes to equipment such as signaling devices and protective gear. There are five areas in which technology has played a significant role in the realm of outdoor and adventure recreation:
  • access and transportation,
  • comfort,
  • safety,
  • communication, and
  • information.
Each of these areas has resulted in greater use of the outdoors, differing expectations, and changes in public policy.
For example, technology has increased access and transportation through improvements in overland travel such as snowmobiles and off-road vehicles (ORVs). These machines have allowed visitors to get further into remote areas faster and with less effort. Likewise, comfort in the outdoors has been substantially improved through lighter weight, more effective clothing, tents, boots, and so on. This reduced weight coupled with greater effectiveness has resulted in more people, within a greater age range and across ability levels, to get into extremely remote or challenging areas.
Technology has worked in two ways that relate to safety. First, improved technology has increased the level of safety available to both individuals and groups. By and large, equipment is stronger, lighter, and more versatile, though in some cases higher levels of skill and expertise is necessary to use it. For example, dive computers have essentially replaced dive tables for diving. Although reliable and extremely useful, they also require divers to understand how to use them with enough competence to capitalize on the safety features they provide.
Second, communication is the area experiencing the fastest technological growth. With the advent of GPS units, 36-mile radios, PLBs and EPIRBs (personal locator beacons and emergency position indicating radio beacons), satellite telephones, smart phone apps, and increased cellular coverage, technology now allows outdoor enthusiasts to know precisely where they are, how fast they are moving and in what direction, and how to signal for help—all at the press of a button. The potential danger of these technological advances lies in two areas. First, knowing what direction and exactly how far you need to go to reach a particular point might make you more likely to go for it, but there’s no guarantee you will actually reach your destination. Ravines, canyons, mountains, steep slopes, avalanche areas, and severe weather may all conspire to make sure you don’t get where you want to go. Second, technology sometimes does not work. Just as helicopters cannot always fly to your location, a GPS or handheld radio might not be in operation for a variety of reasons, such as dead batteries, remote location, or exposure to elements such as rain.
Historically, information was often obtained through word of mouth, asking the area ranger, or finding a map or brochure. Now, within the context of outdoor recreation and adventure, information is usually accessed via the Internet, automated telephone exchange, or guidebooks. Again, this ease and convenience of accessing information generally leads to increases in use, particularly in areas that have not seen much use because of their remote or difficult location.
This increased use, however, does not come without a price, namely in visitors finding themselves in situations far more challenging than their skill or knowledge levels can accommodate. Added to this, they are often in locations so remote that no one can easily get to them. Technology can also create a deceptive “bubble of safety.”

That is, when substituted for skill or expertise, technology can create an illusion of safety or security that allows people to become complacent, only to discover, perhaps at a critical moment, that no such safety mechanism exists (Ewert & Shultis, 1999). For example, an avalanche beacon can be a lifesaver, but no beacon ever prevented an avalanche from occurring, and if you are buried by one, your chances of survival are automatically decreased by 50 percent.
In sum, technology has contributed a number of benefits to OAE activities and participants. It has increased comfort and safety, improved access, enhanced communication, and enlarged the information base from which we make decisions. It has also been known to create illusions of safety and might create a different set of expectations in relation to outdoor settings. Underskilled participants can find themselves in situations that require search and rescue (SAR) or other forms of assistance from managing or government agencies. In such cases, technology serves to increase demands on the environment and land resources rather than decreasing them.

Technology advantages and disadvantages

The impact in technology in our lives, today, is unmeasurable. We use technology every day, in different ways and we do it to harming up our lives or the society we live in. But what we are used to call modern technology, technically it is not as new as we think.
For instance, if we have a great smartphone today we can figure out that it is just an advancement of an ordinary mobile phone that we had years ago. Or look at a train today – we used to use steam powered trains and now we have electronic trains – just to get faster to some place. The technology evolves, but it finds old ways and old technologies to evolve.
We use technology every day, in order to fulfil specific tasks or specific interests. We have specific needs and we want to have faster technologies.
So, what are the advantages and disadvantages of the so called “Modern Technology”? Take a look below.
Advantages
  • Improved communication – advanced communication technology tools;
  • Easy access to information – at anytime and anywhere;
  • Improved housing and lifestyle – most of the items that we have in our homes today are automated (if we compare with houses in the 70´s, 80´s, 90´s);
  • Improved entertainment - we have more video games now, good music to listen and visual systems like smart TV's;
  • Social Networking – great improvement for individuals and businesses;
  • Convenience in education – online and mobile education;
  • Convenience of traveling – very important in our lives and in the business world;
  • Changed the health industry – modern technology in hospitals, reducing the mistakes made by doctors and evolving the patients treatments; 
  • Efficiency and productivity – helping businesses increasing production, saving time and money in the industry;
  • Encourages innovation and creativity – it is very easy to start a job today (while at home). A good example is kickstarter.com which helps creative people get funds for projects through crowd funding.
Disadvantages
  • Job loss – replacing humans;
  • World destruction weapons – increasing endless wars;
  • Increased loneliness – social isolation;
  • Competency – increased dependency on modern tools that reduces our creativity and intelligence.

What is it the technology


Project of english:



What is it the Technology ?
Technology is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, etc. or it can be embedded in machines, computers, devices and factories, which can be operated by individuals without detailed knowledge of the workings of such things.
