O que significa um “sistema aberto”

Vou escrever um post bastante sucinto sobre este assunto..

Nos ultimos dias muito se tem falado do negocio Nokia-Microsoft, sobre o porque de uma companhia como a Nokia, que a seu tempo revolucionou todo um sistema de telefones e de UI nos mesmos, vir agora aliar-se a uma companhia em que teve muito pouco sucesso nos SO’s que lançaram para o mercado.

Hoje saiu uma noticia que vem contrariar todas as razões que a NOKIA teria para escolher o WP7.

Wyatt cited timing issues and concerns about Windows Phone 7 not being open source as the reasons behind the decision.  Motorola felt that a closed platform did not afford them the opportunity to create unique value. Wyatt added that going with Microsoft would create a situation where the only value Motorola could offer was “commoditized hardware”.

Ora quem diz isto é o responsavel da Motorola (fonte) ao qual dou bastante razão. Sendo o WP7 um sistema fechado e com um ecossistema também ele fechado (à semelhança da Apple) o que pode uma marca fazer para se diferenciar no mercado?

Vejam o caso do Android, a HTC faz equipamentos com as caracteristicas que bem entende que deve vender, coloca Android e personifica-o como quer e bem lhe apetece. A Samsung / LG / Motorola fazem exactamente o mesmo, e cabe aos utilizadores escolher o UI / hardware / preço que mais lhe convem… pq no fim do dia todos vão jogar os mesmos jogos na mesma plataforma… No WP7 isso não acontece o equipamento é diferente sim, mas a UI é sempre a mesma e a inovação que as marcas podem fazer a esse nivel são bastante limitadas…
Quem perde, na minha opinião, é a diversidade de escolha de todos nós consumidores.

Microsoft Direct Access Design Guide

Looks like Microsoft released Direct Access Design Guide on their download site.
As one of the most valorous features on Windows Server 2008 R2 it should be a really turn-point on the subject of Remote Access over the next few years..
Quoting Microsoft:
Brief Description
This guide provides information about advantages, disadvantages, requirements, recommendations, and design considerations for deploying DirectAccess. It answers the “What,” “Why,” and “When” questions a deployment design team might ask before deploying DirectAccess in a production environment.

Microsoft Software on Goverment…

Our dear and beloved Portugal has currently ongoing 2 sets of election, on for the National Goverment and another the the City Hall.

I remember seeing some months ago something about Microsoft software usage on a National level, what I’m not currently familiar with, is the usage on local level… Let me explain.

How exactly is the administration done on a City Hall? Does it change from city to city? Is there a national “set of rules” for it?

Being a Microsoft fan, I could explain here the tremendous benefits of using an Active Directory for limit some resources usage and even a better network administration
, but what for? For what I know they (City Hall) dont even use such techonology, even though the software is there.

And here lies one of the big dificulties I’ve came across with. When you’re talking “tech” to “non-tech” people in some vague consulting I’ve done over the past months I can say that is way to hard to explain how to use some technologies even if they dont require any kind of investment.

Seriously… Workgroup based network on a City Hall? No permissions on user accounts? How can a Goverment facilitie live like that? I know some small bussiness (4 people max) that even have a SBS Server installed … I seriously hope the people who win this election really start thinking more about this kind of things…

Good stuff has been done indeed (like a public wireless network that covers all the main public buildings) but the IT Department (if there is a dedicated one) should really start thinking about this stuff…

PS 1 : No I won’t even mention that (for what I’ve heard) they use a POP3 external server….
PS 2 : Exchange do exist in this world….
