Founder @ SeeSaw, Padua, Italy. Technical talks, reflections on craft and career, stories from the trenches of running a software company. I care about removing waste from how we build. https://speakerdeck.com/fuzziness 2013-03-30 07:17:11 -0400 Postgres, Redis, or LLM? Ask any engineer, and you already know the answer: it depends. On what, exactly? Usually, there are four things: speed, cost, complexity, and quality. This talk adds a fifth column to that table and shows how to fill it in. Three real Ruby implementations of semantic image search are run on the same dataset and machine, and compared on grams of CO₂e per query alongside the usual four axes. The deck includes the measurement method, the formula, the Ruby snippets, and the numbers — but no recommendation. Just one column you probably didn't have before.

Cloni, Pull(i), Commit(ti), push(i) ...niente di più semplice, vero? ...ma ti è mai capitato di aggiungere un commit sul branch sbagliato (ed ovviamente push-ato sul repository remoto)? ...o di voler correggere il tuo codice con un singolo commit preso di un branch completamente diverso (ma niente altro)? ...mai trovato intrappolato in un conflitto di merge mentre git ti trascina nella tana del bianconiglio? Niente paura, abbiamo un paio di comandi esotici che renderanno più semplice la tua vita da programmatore (e quella dei tuoi colleghi).

A clear idea of the benefits/pitfalls that this approach brings is crucial for a successful adoption in a project. In this presentation I share some of the experiences made during the dismantling a monolithic application into microservices. I analyze some of the reasons justifying the adoption of this type of architecture, talk about the most important issues to consider and reveal some approaches that have been successful in our experience. Topics (among others): microservices, monolith, communication, async messaging, rabbitmq, circuit breaker, conway law, devops, sacrificial architecture. Talk presented at Codemotion 2016 in Rome.
