Augmented Reality with the Metro Paris Subway App

The Metro Paris Subway  iPhone application must be one of the coolest uses of augmented reality I’ve seen. Next time I’ll go to there I’ll must try out (assuming the problems with Android version are solved).

A “non geeky” review of Google Maps Navigation for Android

You probably have read a lot of things about about the new feature released in Google Android 2.0Google Maps Navigation, a free turn-by-turn navigation system for Android mobile devices (also refered as standalone GPS terminal killer). And probably you have read it in a technology or gadget news source, but it’s about time to ear it from an unbiased source, or at least one that doesn’t care about Google’s “cool factor” and won’t evaluate the “geeky” aspects of the device. Fortunately the guys at AutoBlog have came to the rescue and provided a different perspective:

Chrome OS, o sistema operativo só para a Internet

Texto publicado originalmente no Diário2

A Google sempre quis que os utilizadores estivessem permanentemente online. Com o Google Search criou o hábito de não ser preciso guardar nada encontrado na Internet, pois é sempre possível encontrar seja o que for, o Gmail foi o primeiro serviço de email de massas com espaço de armazenamento suficiente para não ser obrigatório apagar mensagens e o Google Docs leva o “Office” para fora do disco rígido. Um dos próximos passos da Google será um sistema operativo próprio, o Chrome OS, e como não podia deixar de ser será muito orientado para a web, mais do que os utilizadores provavelmente estarão habituados.

Apesar de o Chrome OS apenas estar previsto para daqui a algum tempo, a data estimada de lançamento é final de 2010, é já possível testar as suas funcionalidades através de uma versão de teste do Chromium OS, o projecto open source que lhe serve de base. E não poderia ser um sistema operativo mais simples e básico, e o facto de ter o mesmo nome do navegador da Google não deixa enganar: o sistema operativo é o navegador, e apenas o navegador. Não existem aplicações a instalar, não existem utilizadores a criar ou configurar.

O arranque, extremamente rápido, leva-nos a um ecrã de autenticação, onde obviamente são usadas as credenciais do Google (ou Google Apps) para iniciar o sistema. Após este passo temos apenas uma janela com o já conhecido navegador Chrome ligeiramente alterado: uma pequena página de inicial com acessos rápidos aos serviços da Google e as mais conhecidas redes sociais (Twitter, Facebook, etc.). E na verdade resume-se isto, não é possível instalar aplicações externas, tanto mais que núcleo do Chrome OS é iniciado em modo de leitura (um sinal muito claro da Google que trata-se de um sistema “virado para a cloud”), nem alterar definições que não as do navegador. Aqui as aplicações serão os sítios abertos nos separadores do navegador, os serviços estarão todos fora do computador e a única possibilidade de adicionar funcionalidade será através da biblioteca de extensões do Chrome.

E o que esperar do Chrome OS? Claramente não é um sistema para substituir o Windows MacOS, ou Linux. A aposta da Google vai para mudar o paradigma, para apenas usar serviços remotos no dia a dia, ou esperar que os utilizadores assumam que na verdade já fizeram essa mudança mas ainda não repararam. Ainda há muita especulação em torno do Chrome OS, mas o mais certo que nem sequer esteja disponível para instalação num computador normal, sendo apenas disponibilizado através de dispositivos específicos que não serão mais que netbooks baratos e sem disco rígido com o sistema operativo já incluído. Resta esperar mais um ano até sair a versão final.

PS – No MakeUseOf existe um excelente tutorial (em inglês) que mostra como testar o Chrome OS a partir de uma pen USB.

Blaze, yet another application launcher (but with a twist)

There’s another contender in the “Application Launcher tools for Windows” department, to get a place among long-time favorites like Launchy or Enso. It’s called Blaze and it adds something new to the typical set of features you may find in tools like this: not only indexes programs and files but, among other things,  it can monitor and detect repetitive tasks. Looks pretty neat, and considering Launchy hasn’t evolved in the last 18 months this might become the ultimate Application Launcher for Windows.

Windows XP looks too tough to die

XP Mode consists of the Virtual PC-based virtual environment and a fully licensed copy of Windows XP with Service Pack 3 (SP3). It will be made available, for free, to users of Windows 7 Professional, Enterprise, and Ultimate editions via a download from the Microsoft web site

Secret No More: Revealing Windows XP Mode for Windows 7 [SuperSite Blog]

For a long, long time Microsoft tried to push Windows Vista to end-users as a replacement for Windows XP, a strategy that failed in many ways: users often "downgraded" to XP, many companies and retail vendors chosen not to upgrade (forcing the extension of XP’s lifecycle) and, in the end, Microsoft was forced to accelerate the development of Vista’s successor: Windows 7 (allegedly a Vista without all the “bloatware”). It seems Microsoft, in a classic case of “if you can’t beat them, join them”, has gone one step beyond with Windows 7: instead of trying to kill XP, there will be an option to run applications in XPM (xp mode), which is nothing more than an instance of Windows XP running in a virtual machine

I bought myself a new toy!


LX3 and my black cat
, by dannysay

This weekend I bought myself a new toy!

For some time I felt the need of yet another camera, something between my fully featured but also bigger and bulkier DSLR and my ultra-portable, always available but less powerful camera phone. So when I started reading all the so many people thrilled I got curious about the Panasonic LX3, and a few reviews later I ended up buying it.

I haven’t tested it properly, but for now it seems it’s exactly what I was looking for: it’s quite small and portable, only slightly bigger than the regular compact camera, but with a helluva lens and a few other features aimed to please photographers.

Windows Update wants to be Apt-get when it grows up

Download Squad listed three Linux applications that “make us hate Windows”: Apt-get (and its graphical interface Synaptic), Compiz Fusion and Amarok.

Compiz Fusion adds Vista and OSX “like” eye-candy to Linux, even in my old laptop, and it’s one of the reasons why current distributions are more appealing in recent years. Amarok is a really neat media player, probably is the best way to sync an iPod in Linux and the next version seems to be quite promising. So both of these tools are great but neither of them makes me feel like I need them everywhere, on every computer I lay my hands on.

But if there’s one thing anyone who uses a Debian based distribution just can’t live without is Apt-get, a better Windows Update that manages the updates of virtually all the installed packages, not only from OS and selected tools (Internet Explorer, Office, etc…), and hardly requires a reboot to apply them (usually only a new kernel requires a reboot).

Control Windows Services with Launchy

I’ve been a long-time fan of Launchy, and most of the other application launchers out there, for some time. And now I found out another good use for this neat little tool:

Top notch noise reduction… and it’s free!

Lately I’ve done most of my photo processing with Gimp, which meant no decent noise removal tool for some time (despite being a great app this is one of Gimp’s handicaps). Fortunately I stumbled upon GREYCstoration a free plugin, as in “free beer” and “free speech”, that brings top quality noise reduction to Gimp, probably the best around right after “camera profile oriented” tools like Neat Image.

Surface teaser

…And now some eye-candy, a teaser for a new user interface from Microsoft, to be released next year, where everything is done just by touch. Literally!…
