READY TO HIT THE WEB: First 3D-Printed Handgun Successfully Test Fired « Secrets of the Fed This is an update to Defense Distributed’s ongoing progress with 3D printed weapons. The eyes of the world are on the innovation of 3D printing. Naturally, whenever a new technology is created that offers open source DIY opportunities to the average individual, it is going to make governments and their protected corporate interests very nervous. Such is the case with 3D weapons manufacturing. Now, after 8 months of discussing the possibility of a fully printable 3D handgun with all parts made of a composite plastic, except for the firing pin, Defense Distributed is set to release the new CAD files to the Web following a successful test fire on Saturday which can be seen in the latest video below. Defense Distributed founder, Cody Wilson, recently granted Forbes a behind-the-scenes look at how his new creation — The Liberator — will function: Wilson has once again drawn Israel’s attention according to the latest update from Forbes: Comments comments

Wonder How To » Show & Tell for Creators & Doers 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).
