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

How do I make games So where do I start? Tetris. Something I need to mention is that when you make your Tetris game, you can't call it "Tetris". However, this means nothing to you if you call your game "The Sky is Falling", or anything without a "tris" in it, as they do NOT own the gameplay, interface, or idea of falling blocks. What's next? Finally, the side scroller has a real victory condition! Get Out The Polish… But, these games are stupid! If you are really interested in making games, then you need to separate your desire to create the next cutting edge, hard core game, and focus on building your ability to do so. Be proud of your games! You don’t hear people in college embarrassed about being in college because they don't have a job yet. When you have a finished product you can show, you need to accept that for what it is, not what it isn't or compare it to people with 5+ years of experience and million dollar budgets who work on games full time. I made my game, now where's my Ferrari?
