TinCan: app dispensa internet e sinal de celular para enviar mensagens

<div style="background-color: white; color: #333333; font-family: arial, helvetica, freesans, sans-serif; font-size: 1.26em; letter-spacing: -0.02em; line-height: 1.45em; outline: 0px; padding: 0px 0px 1.5em;"> Os usuários que desejam trocar mensagens, mas não têm um bom pacote de dados em seus smartphones ou, constantemente, ficam sem sinal no celular, não ficarão mais sem se comunicar. Quem oferece essa possibilidade é o aplicativo <a href="http://www.techtudo.com.br/tudo-sobre/s/tincan.html" style="-webkit-transition: color 200ms ease-out; background-color: transparent; color: #6f1714; font-family: inherit; font-size: 15px; font-weight: bold; margin: 0px; outline: 0px; padding: 0px; text-decoration: none; transition: color 200ms ease-out;">TinCan</a>, disponível para <a href="http://www.techtudo.com.br/tudo-sobre/s/android.html" style="-webkit-transition: color 200ms ease-out; background-color: transparent; color: #6f1714; font-family: inherit; font-size: 15px; font-weight: bold; margin: 0px; outline: 0px; padding: 0px; text-decoration: none; transition: color 200ms ease-out;">Android </a>e, em breve, para <a href="http://www.techtudo.com.br/tudo-sobre/windows-phone.html" style="-webkit-transition: color 200ms ease-out; background-color: transparent; color: #6f1714; font-family: inherit; font-size: 15px; font-weight: bold; margin: 0px; outline: 0px; padding: 0px; text-decoration: none; transition: color 200ms ease-out;">Windows Phone</a>, cuja proposta é disponibilizar o envio de mensagens para pessoas que estão por perto.</div> <div class="foto componente_materia midia-largura-620" style="background-color: white; color: #333333; float: left; font-family: arial, helvetica, freesans, sans-serif; font-size: 12px; line-height: 12px; margin: 0px 1.75em 1.5em 0px; outline: 0px; overflow: hidden; padding: 0px; zoom: 1;"> <img alt="TinCan consegue enviar mensagens para pessoas próximas sem a necessidade de internet (Foto: Reprodução/Paulo Alves)" height="500" src="http://s.glbimg.com/po/tt/f/original/2013/11/13/tincan-consegue-enviar-mensagens-para-pessoas-proximas-sem-a-necessidade-de-internet.png" style="background-color: transparent; background-position: initial initial; background-repeat: initial initial; border: 0px; display: block; font-family: inherit; font-size: 12px; margin: 0px; max-width: 594px; outline: 0px; padding: 0px;" width="620" /><span style="background-color: #eeeeee; display: block; font-family: inherit; font-size: 12px; margin: 0px; outline: 0px; padding: 0.67em;">O TinCan consegue enviar mensagens para pessoas próximas sem a necessidade de internet (Foto: Reprodução/Paulo Alves)</span></div> <div style="background-color: white; color: #333333; font-family: arial, helvetica, freesans, sans-serif; font-size: 1.26em; letter-spacing: -0.02em; line-height: 1.45em; outline: 0px; padding: 0px 0px 1.5em;"> Um misto de mensageiro e microblog, ele funciona por meio da rede Wi-Fi, responsável por formar o elo entre dois ou mais aparelhos. O sistema é utilizado unicamente para vincular os celulares, sem necessidade de estabelecer uma conexão com a internet.</div> <div style="background-color: white; color: #333333; font-family: arial, helvetica, freesans, sans-serif; font-size: 1.26em; letter-spacing: -0.02em; line-height: 1.45em; outline: 0px; padding: 0px 0px 1.5em;"> Em seu funcionamento, a mensagem enviada pelo usuário chega, ao mesmo tempo, a todas as pessoas que têm o app instalado. Há a possibilidade, no entanto, de filtrar o conteúdo recebido em sua linha do tempo de acordo com usuários preferidos.</div> <div style="background-color: white; color: #333333; font-family: arial, helvetica, freesans, sans-serif; font-size: 1.26em; letter-spacing: -0.02em; line-height: 1.45em; outline: 0px; padding: 0px 0px 1.5em;"> Segundo o criador do programa, Mark Katakowski, a utilidade primordial do TinCan ocorre em situações nas quais não há conexão fácil, como em casos de desastres naturais ou em regimes totalitários que impedem sua população de se conectar à internet. O aplicativo, portanto, tem como plano de fundo um papel social importante.</div> <div style="background-color: white; color: #333333; font-family: arial, helvetica, freesans, sans-serif; font-size: 1.26em; letter-spacing: -0.02em; line-height: 1.45em; outline: 0px; padding: 0px 0px 1.5em;"> Apesar de todas essas vantagens, o modo de operação do aplicativo também pode abrir portas para pessoas mal-intencionadas, que poderiam criar vírus e malwares para se aproveitar da conexão direta entre aparelhos. Essa é, inclusive, uma preocupação levantada por Katakowski, que aponta essa situação como um entrave para a aprovação do app pela Apple.</div> <div style="background-color: white; color: #333333; font-family: arial, helvetica, freesans, sans-serif; font-size: 1.26em; letter-spacing: -0.02em; line-height: 1.45em; outline: 0px; padding: 0px 0px 1.5em;"> Até agora, cerca de 5 mil pessoas instalaram o app, mas não deram um bom feedback nas resenhas da loja online do <a href="http://www.techtudo.com.br/tudo-sobre/google.html" style="-webkit-transition: color 200ms ease-out; background-color: transparent; color: #6f1714; font-family: inherit; font-size: 15px; font-weight: bold; margin: 0px; outline: 0px; padding: 0px; text-decoration: none; transition: color 200ms ease-out;">Google</a>. É importante destacar, porém, que o programa está em sua versão 1.0 e, por isso, espera-se que tenha bugs em alguns dispositivos. Além disso, não foi reportado nenhum comportamento estranho que indique a presença de vírus ou malwares. </div> <br style="background-color: white; color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; line-height: 18px;" /><span style="background-color: white; color: #333333; font-family: arial, helvetica, sans-serif; font-size: 12px; line-height: 18px;">Fonte: http://www.techtudo.com.br/ -A tecnologia descomplicada-</span>

Um de seus grandes feitos foi a união da geometria com a álgebra, criando assim a geometria analítica em que se obtém imagens a partir de um sistema de coordenadas que recebeu seu nome.
