Functional testing Facebook "Dislike" in a way few people think to

If the button "Like" (favorite) has long been considered a characteristic symbol of social network Facebook, then press the button "Dislike" (Dislikes) are features most desired by many people appear on Facebook .

Last month, Facebook founder and CEO Mark Zuckerberg revealed that social networking is considering the development of the button "Dislike" as a way for users to express anger or disagreement with the message not happy, but Zuckerberg also confirmed that the button "Dislike" that Facebook developers will not like buttons "Like" or what users are thinking.

And now that Mark Zuckerberg promises have come true, as Facebook has just introduced feature called "Reactions" (reaction), is a set of seven different emoticons, including "Like" "Love", "Haha", "Yay", "Wow", "Sad" and "Angry", which users can use this symbol as a way to express feelings and attitudes, rather so just click "Like" as before.

With this new feature, besides the Like button, users can select one of six different emotions of "Reactions" to express their attitude to the content being shared on Facebook. To select one of the feelings of Reactions, users press and hold the Like button on Facebook and choose one of the emoticons appear.

Like the "Like" the total number of people expressing emotions are also used, such a lot of people chose the "Love" (Love) for your article or how many people have expressed feelings "Angry" (Anger) with a certain content. List of those who express different emotions for content on Facebook will also be displayed, just like with a "Like" familiar.

"Over the years, many people have asked more buttons" dislike ". Not all moments are beautiful moments and sometimes you want a way to express empathy ", Mark Zuckerberg explained the new features on its Facebook page. "There are important moments you need the power to share more than ever before and a button" Like "is not the best way to play."

"Reactions will give you new ways to express love, terror, humor and sorrow. That's not the button "dislike", but it will give you the power to easily express the sorrow and sympathy, beyond joy and warmth, "said Mark Zuckerberg share more.

New features are currently testing Facebook for users in Spain and Ireland, before deciding to continue to provide this feature globally widespread or not.

So again Facebook has "shirk" providing buttons "Dislike" for users and features "Reactions" was viewed as a feature "Fire", rather than a real feature users look forward to.

Facebook also has repeatedly explained why social networks are not equipped with the button "Dislike" to users, but one of the most logical reason for that is the button "Dislike" can create relationships Us not good among Facebook users together, instead of creating an empathy and sharing criteria like social network is active.

"The reason we brought the" Like "to Facebook because many people want to admit something that someone has done, but do not want to say or not say anything. And instead of responding to comments like 'great' or 'wow', we bring the "Like" so people can replace words with just one click ", Bret Taylor, former chief technology officer Facebook and also the "father" of the "Like" on Facebook have shared.

"I feel that if there is extra buttons" Dislike "will lead to negative social relationships and not nice. If you do not like what is shared on Facebook, simply write a comment, because that's what you want to say. Anyway button "Like" does not bring negative emotions and complex as the "Dislike" can bring ", Taylor explains why the" Dislike "may not appear on Facebook

There should always be plugged to the laptop or not?

There are many ways you can do to increase the battery life on my laptop, but is there any way to help increase battery life, or not? A discussion of the most controversial in the history of the laptop, it should always be plugged in, or only when batteries charged?

The following article will help you to answer are questions.

1. Understand the battery on a laptop

There are 2 main types of batteries used in laptops: battery lithium-ion and lithium-polymer batteries.

Although using different technologies, but basically, the features of the two batteries similar activities, based on the principle of the electrons move. This flow also keeps the battery life is long wearing.

For the 2 types of battery on a laptop, the two things are correct:

- A battery can not be overloaded when charging. There will be no danger when you are plugged in at the battery is full. The reason is that once reached up to 100%, it will automatically disconnect the power source, and will not continue until the battery charger drops a certain amount. Therefore, the withdrawal of the full battery charging almost do not bring something positive than to let the battery charger plug.

- However, in order to clean the battery may cause damage to the battery life. To pin depleted many times can make it into a state of "deep discharge". At that time, very likely it will not be restored.

2. Factors detrimental to battery

The fact is that even if you have nowhere to preserve battery life will decrease with time, or it is also called "bottle pin". There are several factors that should be avoided, because they will cause direct harm to the battery on your device:

- Charging cycle: Each battery has a number of charging and charging certain withdrawal, aka charging cycles.

- The amount of voltage: the higher charging current, battery life decreases

- High temperature (over 30 ° C): High temperatures can cause irreparable consequences to the pin.

3. There should remove the batteries?

In theory, the pin on all laptops are c removable and replaced. But the answer depends on the different manufacturers. With the Acer laptop, users can enjoy without worrying about the battery removable machine gasp. However with its Mac line, Apple recommends that users do not disassemble the battery to ensure absolute safety.
