37 Tested PHP, Perl, and JavaScript Regular Expressions inShare22 A regular expression, also called regex or regexp for short, is simply a piece of code that matches a pattern. Mastering regular expressions can be a difficult chore, and if you don't need them all of the time, the syntax is tricky enough to make the task frustrating or slow as you will constantly need to use a reference sheet. In order to save you time, I've compiled a list of PHP, Perl, and JavaScript regular expressions for common use cases that have been tested and are ready to go. This isn't a regular expression tutorial or even a reference; you can think of it more as a cheatsheet for when you just need the regex but don't want to put a lot of time into relearning regular expressions. If you're looking for regex tutorials or regex resources, you can find them at the end of the page as well as some additional regex resources.

Desenvolvimento de projetos (/dev/Kico) A questão dos micro serviços ainda me acompanha. Desde a publicação do meu último post sobre o assunto venho recebendo feedback de diversas pessoas além de ter entrado em contato com tantas outras. Com a mente um pouco mais clara (ao menos espero) chegou a hora de expor minhas conclusões correntes sobre o assunto. A grande questão: é SOA? A conclusão que cheguei é quase óbvia: sim e com poucas novidades. Alguém que me influenciou fortemente este ponto foi Steve Jones em um dos seus posts (a propósito, excelente blog). O modelo de referência do OASIS é um documento bastante árido mas que lido com atenção nos fornece um sólido conceitual para entender, de fato, o que é SOA. O que é SOA? Citando o modelo de referência do OASIS, SOA seria (…) um paradigma que visa organizar e usar funcionalidades (capabilities) distribuídas que podem pertencer a distintos donos (ownership domains). Há um conceitual muito importante (e interessante) neste documento que é importante divulgar aqui. Conclusões

Machine Learning Machine learning is the science of getting computers to act without being explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. Machine learning is so pervasive today that you probably use it dozens of times a day without knowing it. Many researchers also think it is the best way to make progress towards human-level AI. This course provides a broad introduction to machine learning, datamining, and statistical pattern recognition.
