How to Recover a Wet Cell Phone

Has your phone already fallen in a puddle of water? On the beach? Most of the time this is a reason to buy a new phone, but if you are fast and do the right thing you can recover your phone.

Follow these steps:

1- Pull it off the water as soon as possible.

The plastic covering the phone is quite thick but the water can enter by all forms. Try unplugging the phone in less than 20 seconds. This will be crucial to save it.

After taking the water, wash it with fresh water (if it have fallen into the sea) and clean it. Look for some flasks that you can put it together with a few grains of rice. It is very absorbent and will eliminate remnants of moisture in a few days.

2 - Take the battery out.

This is one of the most important steps. Do not waste time thinking! The electricity and water do not mix. Disconnect all forms of energy will be crucial to save it. Many internal circuits survive immersion in water.

3 - Take your SIM card out.

Some of your valuable contacts and other data could be stored on your SIM card. For some people this could be more valuable that the cell phone. The SIM cards survive in the water. Simply dry it and leave it aside until you need to use it again. Remember that many phones do not use SIM cards.

4 - Dry your phone.

You obviously need to take the greatest possible volume of water out as soon as possible. Use a paper towel to dry it.

Let the phone drying. Do not place the battery back to see if it works, it could generate a short circuit and destroy your phone.

5 - Warm the phone up.

Heat it up so the water evaporates without damaging the circuits. You can put it behind your computer’s cooler, so the wind makes the water evaporate. Leave the phone there for 2 or 3 days. Or you can use a hair dryer to do the work for 2 hours. But beware not to place the hair dryer too close to the phone because the wind could be too hot! The hair dryer could be set to the warm position (not hot) some 20 cm (8 inches) far from it.

6 - Test your phone.

After waiting for 3 days, put the battery back in place and make sure the phone works. If that does not work, repeat steps 4 and 5. If it still does not work, take it to an authorized technician.

How to Use Wikipedia

Wikipedia is on the Internet for several years and was founded with the idea that any person has knowledge that can share with others. That’s the exact reason why the Internet was invented. The problem with Wikipedia is that anyone can edit its content, in any text, the way he/she wants, no matter if he/she has knowledge about the subject.

Therefore, many teachers do not allow their students to use Wikipedia as a source of reference in their school or college work. Some students even argue saying that the content of the Free Encyclopedia is always verified and receives updates every day. This is not true.

If you have found some information that you really want to use, here are some tips for you to make sure that the information is correct:

1) Read the text! Yes, this may sound obvious but you would be amazed to know how many people do not even read their references. As the site can be edited by anyone, it may contain several types of grammatical errors or other types. If the text is well written, easy to understand and make sense, then go to step 2.

2) Compare with reliable sources: If you are writing a paper on something like the French Revolution, you must already know something about the subject. If you have in hand some work published, as a book on the topic, you can compare some points to check whether the content of Wikipedia makes sense.

3) Check the references: Many students insist that the Wikipedia is safe because there are several references in all texts. This is not true. Only because there are reference links, it does not mean that such references are safe. Remember that we are on the internet. Always check those links, see where they come from and, if this site is well known to be correct, use that as a reference instead of Wikipedia.

4) Check the author: Who wrote the text? The page author will usually leave a link with information about himself and sometimes a form of contact. If the author or member of Wikipedia is not mentioned then the information cannot be considered secure.

It all seems a lot of work for a simple reference and, well, really is. If you use books as reference, you will not need any of these steps. But if you chose to use the Wikipedia, follow these four items and don’t forget to inform the date that you accessed the document.

Most importantly, ask your teachers about what they think of using the Wikipedia as a source of reference.

How to Use the Netiquette in E-mails

Writing e-mails sounds a really easy thing to do but writing isn’t as simple as we usually think. Writing in an inappropriate manner may cause situations of misunderstanding and stress in the interaction with other people. That may be caused by the absence of voice inflection and body language in the transmitted messages.

Therefore, to avoid those situations, there were created standard rules according to the type of network and service, which usually follow general rules of common sense to help in that interaction. These standard rules of good manners or etiquette are called Netiquette.

Following are some basic rules for writing e-mails.

1) Be clear and objective. Produce texts of easy reading.

2) Pay attention to spelling and grammar and check them at the end. People’s impression on you on the Internet will come only through what and how you write.

3) Separate paragraphs with blank lines.

4) Pay attention to use the Reply command when responding to a message and the forward command when moving forward an e-mail. This avoids confusion and an unnecessary message return to sender.

5) Consider addressing only one subject per message.

6) Choose an appropriate title related to the discussion in the message to put in the Subject. This is important for anyone with a packed mailbox to decide when, or even whether or not, to read your message.

7) To emphasize phrases and words in unformatted text (when the software does not support the Rich Text or HTML formats) use the resources of _underline_ (putting words or phrases between underscores) or *asterisk* (putting words or phrases between asterisks).

8) If you wish, you can assign "signatures" in your e-mail software. These “signatures” are information that can be automatically placed at the end of your message to help your readers identify you. This “Signatures” can be preprogrammed in your e-mail software.

9) A signature with name, the company name that you work for if you’re at work, phone and fax numbers is usually sufficient. Avoid too long signatures with drawings.

10) The use of upper and lower case letters are the same as in the common writing.

11) Be careful. To write with capital letters on the Internet is the same as shouting.

12) Consider answering all your personal messages because the people who address you might be expecting an answer.

13) When answering messages, do not include the entire contents of the message answered. Rewrite just the points that you are commenting on or the sentence that you are responding to.

14) When answering messages, especially on discussion boards and groups, make it clear which messages and what subjects you are responding to.

15) Some e-mail software still today automatically put up a ">" (greater than) sign at the beginning of each phrase copied from the original message as it was established. Every time a message is answered in a cascade, the citation receive a new ">" sign on each line forming multiple signs like “>>>”. But today this system is becoming out of use, as most e-mail programs separate a message from the other with a line.

16) Send attached files only when requested.

17) Use “Emoticons” when necessary to show emotions. To compensate for the lack of inflection of the voice and body language existing in the face-to-face communications, the network developed symbols called Emoticons or Smiles to avoid misinterpretations in the transmitted messages. The Emoticons are icons formed by points, commas, parentheses and other symbols of the keyboard and represent horizontally drawn faces to show emotions. Their creation is attributed to Scott Fahlman (http://en.wikipedia.org/wiki/Emoticon) in 1982.

: -0 Astonishment, surprise
