How open source has changed the hardware environment
While open source software is a relatively well-known concept by comparisons, the idea of open source hardware isn’t quite as publicized. In fact, few people are aware that there are quite a few organizations offering open source hardware, which meansthey have made all information pertaining to their products freely available, including designs and schematics, bill of materials information, and printed circuit board layout data. Generally, open source software is used in the original design, which provides evenmore benefits.
The driving ideology behind open source hardware is that anyone should have the freedom to:
• Use the device for any purpose.
• Study how it works and make any changes.
• Redistribute the design of the device and the device itself.
• Enhance the design as well as the device and make those improvements freely available to the public so all can benefit.

We take software for granted, but it's obviously crucial to getting any work done on a computer. It's what makes computers and smartphones and tablets (and these days, for that matter, cars, televisions, and microwave ovens) actually do things. Without it, your computer or other device is simply a case with nice buttons and lights.

The sentence “Without it, your computer or other device is simply a case with nice buttons and lights" means that:

Smart Greenhouse
Control the light, watering, temperature, and humidity of your greenhouse – automatically.
Kevin Farnham
Smart Greenhouse, one of three professional category winner in the 2014 IoT Developer Challenge, is an Internet of Things (IoT) device and application that monitors and controls a greenhouse environment. The concept for Smart Greenhouse came into being after the core team – Dzmitry Yasevich, Pavel Vervenko, and Vladimir Redzhepov – attended JavaOne Russia in April 2013. There, the team saw presentations of a smart house, various robots, and other devices, all controlled by Java.
Yasevich notes, “We were impressed by these solutions and had an idea to do something like that. Pavel Vervenko suggested making an automated greenhouse. Everyone liked the idea!”.
First, the team selected the hardware. “We started to use Raspberry Pi as a basis”, Yasevich says. “It is a compact but fullfedged computer with 700 MHz and memory at 512 MB. This system costs around $35”.
However, early on, a safety concern arose. “Current under high voltage passes in the greenhouse, and there is an automatic watering system, so it was necessary to properly consider all the aspects related to insulation”, Yasevich says.

1. O que se pretende, com a implementação de controles internos, é: i) a garantia da observância às normas vinculantes; ii) a confiabilidade e tempestividade das informações; iii) a prevenção a erros e fraudes; iv) a salvaguarda dos ativos; v) o aperfeiçoamento do Sistema de Controle Interno; e vi) a governança institucional.
2. Os profissionais que executam atividades específicas dentro das várias modalidades das categorias da área tecnológica devem assumir a responsabilidade técnica por todo o trabalho que realizam.
3. O que distingue o profissional de TI perante a sociedade é o conhecimento sobre computadores, suas teorias e métodos, o que se pode ou não fazer com os computadores e como fazer. O conhecimento, entretanto, traz responsabilidades, e nesse aspecto o princípio fundamental, na dimensão da ética profissional, é não causar danos aos artefatos computacionais sob a responsabilidade do profissional.
4. Dentre as responsabilidades normalizadas para o profissional de TI está a auditoria. Cabe a esse profissional, no papel de auditor, compreender as informações utilizadas pelo auditor para chegar às conclusões em que se fundamenta a sua opinião.
Assinale a alternativa correta.
( ) A abrangência da atuação da área de TI é estabelecida pela Lei 1.561/2003, que regulamenta o exercício profissional da área.
( ) Segundo a NBC TA 330, procedimento substantivo é o procedimento de auditoria planejado para detectar distorções relevantes no nível de afirmações.
( ) A NBC TA 330 define teste de controle como o procedimento de auditoria planejado para avaliar a efetividade operacional dos controles na prevenção ou detecção e correção de distorções relevantes no nível de afirmações.
Assinale a alternativa que apresenta a sequência correta, de cima para baixo.
( ) O controle de acesso e segregação de funções em um ambiente de TI exige, além do uso de tecnologias específicas para esse fim, o estabelecimento integrado de gestão de identidades, análises de risco, procedimentos de autenticação, autorização e inclusão e revogação de acessos, dentre outros processos correlacionados ao tema.
( ) Os Servidores de Banco de Dados podem apresentar-se em três estados (modos) diferentes: produção (em que se realiza a operação normal); simulação e teste; e atualização de kernel.
( ) Existem dois tipos específicos de backups remotos: o “1-safe" e o “2-safe". No modelo “1-safe", a grande maioria das transações realizadas no Banco de Dados principal é automaticamente propagada para o Servidor de Backup e então aplicada.
( ) O gerenciamento de incidentes é preconizado na NBR 23456 e celebra a criação de fluxos alternativos quando da ocorrência de incidentes que impactem dados, fluxos e processos instanciados em Sistemas de Informação.
Assinale a alternativa que apresenta a sequência correta, de cima para baixo.
1. Entende-se gestão de mudanças como o conjunto de processos, ferramentas e técnicas para gerenciar questões ligadas aos objetos físicos sob o escopo de um projeto de TI, em um cenário de mudança, com foco no alcance de melhores resultados.
2. O COBIT tem por foco garantir a ligação entre os planos de negócios e de TI, definindo, mantendo e validando a proposta de valor de TI, alinhando as operações de TI com as operações da organização.
3. Segundo a norma NBR ISO/IEC 17799, convém que os planos sejam desenvolvidos e implementados para a manutenção ou recuperação das operações, assegurando o acordo de serviço estabelecido.
4. O COBIT, no seu capítulo de desenvolvimento de software, estabelece os processos a serem seguidos pela área de TI, de maneira a desenvolver soluções compatíveis com as boas práticas reconhecidas para esse contexto.
Assinale a alternativa correta.
