Effective software project management focuses on the three P’s: people, problem, and process. The order is not arbitrary. The manager who forgets that software engineering work is an intensely human endeavor will never have success in project management. A manager who fails to encourage comprehensive customer communication early in the evolution of a project risks building an elegant solution for the wrong problem. Finally the manager who pays little attention to the process runs the risk of inserting competent technical methods and tools into a vacuum.

For mobile computers and telephones, cellular radio is the up-and-coming technology. GSM, CDPD, and CDMA are widely used.
The IEEE 802 LANs are: CSMA/CD, token bus, and token ring. Each of these has its own unique advantages and disadvantages, and each has found its own user community and will probably continue to serve that community for years to come. Convergence to a single LAN standard is an unlikely event. A new addition to this family is DQDB, being sold as a MAN in many cities.
An organization with multiple LANs often connects them with bridges. When a bridge connects two or more different kinds of LANs, new problems arise, some of them insoluble.

The Object-Relational (OR) model is very similar to the relational model; however, it treats every entity as an object (instance of a class), and a relationship as an inheritance. Some features and benefits of an Object-Relational model are:
• Support for complex, user defined types
• Object inheritance
• Extensible objects

A domain constraint implies that a particular attribute of a relation is defined on a particular domain. A domain constraint simply states that values of the attribute in question are required to belong to the set on values constituting the underlying domain.

Software components are built using a programming language that has a limited vocabulary an explicitly defined grammar and well formed rules of syntax and semantics. At the lowest level the language mirrors the instruction set of the hardware. At mid-level programming languages such as Ada 95, C or Smalltalk are used to create a procedural description of the program. At the highest level the language uses graphical icons or other symbology to represent the requirements for a solution. Executable instructions are automatically generated.

A ciência do humor
Na média, nós rimos entre 15 e 20 vezes por dia. Mas a variação entre indivíduos é grande. E não só entre indivíduos. Mulheres riem mais do que homens, mas são piores contadoras de piadas. E, à medida que envelhecem, elas tendem a rir menos, o que não acontece com eles. Também preferimos (todos) rir à tarde e no início da noite.
Um bom estoque de informações como essas, além daquela que foi considerada a piada mais engraçada do mundo, está em Ha!: The Science of When We Laugh and Why (Ha!: a ciência de quando rimos e por quê), do neurocientista Scott Weems.
O livro é interessante sob vários aspectos. Além das já referidas trivialidades, cujo valor é intrínseco, Weems faz um bom apanhado de como andam os estudos do humor, campo que apenas engatinhava 30 anos atrás e hoje conta com sociedades e artigos dedicados ao tema.
O que me chamou a atenção, entretanto, é que o autor propõe um modelo um pouco diferente para compreender o humor, que seria um subproduto da forma como nosso cérebro processa as dezenas de informações conflitantes que recebe a cada instante. Embora nós gostemos de imaginar que usamos a lógica para avaliar as evidências e tirar uma conclusão, trabalhos neuro-científicos sugerem que a mente é o resultado de uma cacofonia de módulos e sistemas atuando em rede. Vence aquele módulo que grita mais alto. Frequentemente, o cérebro aproveita essa confusão para, a partir da complexidade, produzir ideias novas e criativas.
Quando essas ideias atendem a certos requisitos como provocar surpresa e apresentar algo que pareça, ainda que vagamente, uma solução para o conflito, achamos graça e sentimos prazer, que vem na forma de uma descarga de dopamina, o mesmo neuro-transmissor envolvido no vício em drogas e no aprendizado.
Basicamente, o humor é o resultado inopinado de nosso modo de lidar com ambiguidades e complexidades.
