Role of NFC in the future of Digital Wallet
“Since the beginning of a barter economy on our planet, personal Wallet seems to have remained stuck in the leather and bone ages, literally. I believe: Wallet is the next frontier for Enterprise and the next killer App for Mobile. Digitization of wallet is inevitable.
O caminho das pedras do HTML5
Um dos desafios de desenvolver utilizando o HTML5 é saber escolher com precisão as APIs nativas que se pretende utilizar. Digo que é um desafio, pois por não ser uma especificação ainda finalizada, a implementação das APIs nativas do HTML5 não é tão consistente como se imagina entre diversos navegadores. Existem áreas específicas, como suporte básico a Canvas ou o Local Storage, que já são amplamente suportadas de modo uniforme entre os navegadores, mas em outras áreas, como Web Audio e IndexedDB, a implementação não é ainda regular - mas tende a ser em breve.
Developers Are “Rock Stars” and "Wizards" at Code.org
A new non-profit foundation with the primary aim of getting more people coding has emerged this week, complete with an introductory video with the likes of Mark Zuckerberg, Bill Gates, and Will.I.Am (yes, THAT Will.I.Am!) touting the benefits of software programming. The non-profit is Code.org, and they want to help kids, parents, and schools learn how to program.
Android SDK 的一个bug ------ parameters.getFocusDistances 无法使用(被拍摄物体和摄像头之间的距离无法测量)
这是很早之前我发现的一个问题,当时想利用“焦距”来定位被拍摄物体和手机摄像头之间的距离,注意不是摄像头预览画面里两个点之间的距离,这是个平面距离。本文所说的距离是垂直距离。最终失败,原因是parameters.getFocusDistances返回的值永远是inifinte。手机型号是华为U9200.
下面是测试核心代码:
<SPAN style="FONT-SIZE: 18px">@Override
public void onAutoFocus(boolean success, Camera camera) {
//READ FOCUS DISTANCES HERE
Camera.Parameters parameters = camera.getParameters();
float[] distances = new float[3];
if (success) {
