How Bad Do You Want It?

Image
That's commitment “I’m here to tell you, number one, that most of you say you want to be successful, but you don’t want it bad. You just kinda want it. You don’t want it as much as you want to party.” “Some of you love sleep more than you love success! If you want to be successful, you’ve got to be willing to give up sleep. How bad do you want it?” “When you want to succeed as bad as you want to breathe, then you’ll be successful” Some of my favorite quotes by the narrator in the video  “How bad do you want it” . Whatever your bigger goals are in life, what are you willing to do achieve it? Are you willing to make sacrifices? Work when others are sleeping? Eat only ramen noodles? Breakup with a girlfriend/boyfriend who is holding you back? You may think you want it so bad, but do you really? Any area of life where you want success isn’t going to happen overnight. If you think it’s going to be easy, this post will be a waste of time for you. If you’re trying

Ubuntu 12.04 LTS - Unity 5.0/HUD

Image
Mais ou menos uma vez na semana, eu baixo e instalo do zero a imagem diária (Daily Build) do Ubuntu 12.04. Faço isto porque é a melhor maneira de ter o sistema perfeito, sem arquivos desnecessários, que já não são mais usados, e, também para não perder outros que são importantes e que muitas vezes são deletados durante uma atualização (principalmente as ditas parciais). Uma atualização mal realizada pode desestabilizar, ou mesmo derrubar o sistema. É verdade também que várias vezes a imagem diária tem problemas, principalmente de instalação e é preciso esperar a próxima para acertar tudo. Na última imagem diária que baixei, por exemplo, já havia o Unity 5.0 por padrão (ainda não o HUD) e provavelmente não teria percebido se tivesse só atualizado. E, como o Unity 5.0 já é padrão e o HUD pode ser instalado pelo ppa, resolvi dar uma conferida no resultado final. E, como sempre, acabo fazendo um vídeo. O vídeo é simples e subjetivo e não tem outra pretenção que não seja mostrar

WhatsApp Security concerns

In May 2011 there was a security hole reported in WhatsApp which left user accounts open for hijacking. [8]  According to some sources, it is believed that this hack was performed, and later fixed by helping WhatsApp reproduce it on Android and Symbian, by Liroy van Hoewijk, CEO of CoreISP.net. [9] [10] Communications made by current WhatsApp versions are not encrypted, and data is sent and received in plaintext, meaning messages can easily be read if packet traces are available. [11] In September 2011 a new version of the WhatsApp Messenger application for iPhones was released. In this new version, the developer has closed a number of critical security holes that allowed forged messages to be sent and messages from any WhatsApp user to be read. [12] On January 6, 2012 an unknown hacker published a website (WhatsAppStatus.net) which made it possible to change the status of an arbitrary whatsapp user, as long as the phone number was known. To let it work it only required a re
