Lançada a comunidade de HTML5 no Intel Developer Zone no Brasil

É com imensa satisfação que anuncio a criação da comunidade de desenvolvimento de apps com HTML5 no Intel Developer Zone, com todo o conteúdo disponibilizado em Português.

São diversos artigos com informações técnicas e dicas valiosas para ajudar aqueles que possuem apenas conhecimentos básicos em HTML, CSS e JavaScript a aprender com rapidez e efetividade tudo o que precisam para iniciar o desenvolvimento de aplicativos móveis em plataforma cruzada utilizando HTML5.

Neat HTML5 features: Offline Web Applications

Since I work quite a bit with HTML5 I decided to write about it whenever I discover a feature that I think is quite neat. So this blog post is about “Offline Web Applications”. This is based on the functionality described here: http://www.whatwg.org/specs/web-apps/current-work/multipage/offline.html. If you take a look at it you’ll find that this is rather cryptic and dry. So here is a short step by step description on how this works.

GCC x86 code size optimizations

      The time when programmers did their best to minimize an application code size have gone. The root cause is in significantly increased memory and hard drive sizes on PCs during past several years. The only exceptions are programmers writing code for embedded systems. They usually have tasks like: “You need to develop the particular algorithm. Your program should fit N bytes and use not more than N bytes of memory”. Today phones and tablets move programmers “back to the future”?

Hackathon Intel na Unicamp: 2 dias de pura diversão com HTML5 !

Nos dias 3 e 4 de dezembro tive o prazer de organizar, pelo grupo de Software da Intel, um Hackathon com foco no desenvolvimento de Apps educacionais com HTML5 para Android na UNICAMP em Campinas, São Paulo. Contamos com 26 desenvolvedores, que durante dois dias desenvolveram 7 aplicativos educacionais e de código aberto.
 

Android开发中的多线程编程技术

Soumis par jing M. le

多线程这个令人生畏的“洪水猛兽”，很多人谈起多线程都心存畏惧。在Android开发过程中，多线程真的很难吗?多线程程序的“麻烦”源于它很抽象、与单线程程序运行模式不同，但只要掌握了它们的区别，编写多线程程序就会很容易了。下面让我们集中精力开始学习吧!

　　多线程案例——计时器

　　我在给我的学生讲多线程的时候都会举一个计时器的案例，因为计时器案例是多线程的经典应用。

　　这个案例中，屏幕启动之后，进入如图8-1所示的界面。

　　屏幕上有一个文本框用于显示逝去的时间，此外还有一个“停止计时”按钮。案例的用例图如图8-2所示。

    • From ARM NEON to Intel MMX&SSE- the automatic porting solution, tips and tricks

    I love ARM. Yes, I do. - Why do I work for Intel then? Because I love Intel even more. That's why I'd like to help independent software vendors to port their products from ARM to Intel Architecture. But if and only if they would like to do it.

    有关Tizen 2.0 alpha中wrt相关工具的介绍

    在Tizen 2.0 alpha的repo中,我们可以看到很多有关wrt相关的软件包, 比如

    http://download.tizen.org/releases/daily/2.0alpha/ivi/tizen-2.0_20121015.6/repos/main/source/wrt-0.8.91-slp.4.1.src.rpm

    http://download.tizen.org/releases/daily/2.0alpha/ivi/tizen-2.0_20121015.6/repos/main/source/wrt-installer-0.0.54-slp.4.1.src.rpm

    等,下载下来后解开查看源代码,可以发现里面包含有各类wrt相关工具的参数和使用方式及其介绍, 比如最为常见的wrt-installer, wrt-launcher,wrt-client等

    比如

    wrt-installer-0.0.54\src\wrt-installer\wrt_installer.cpp

    有关Tizen 2.0 alpha IVI在PineTrail平台上的体验

    在http://download.tizen.org/releases/daily/2.0alpha/ivi/tizen-2.0_20121015.6/images/pinetrail-2.0/pinetrail-2.0-tizen-2.0_20121015.6-sdb.raw.bz2可以下载Tizen 2.0 alpha IVI对应在PineTrail平台上的image

    下载以后可以通过bunzip2解压,然后dd burn到U盘上, 从一台PineTrail上网本启动

    可以看见

    有点和Phone的界面相近

    在http://download.tizen.org/releases/daily/2.0alpha/ivi/tizen-2.0_20121015.6/repos/有相关的源代码,大家有兴趣可以多研究研究
