Software engineering for beginners. The worst codebase I’ve seen in my life. March 30th, 2011. I recently inherited a huge legacy project (let’s call it FailApp) which features brutally substandard code. I’ll present the best gems here, not as a rant, but as a case study of what is possible to be delivered in the software industry for a six figures sum of money. The gems are categorized in three levels and (due to popular demand) each contains an oneliner of what the author should have done instead.

My blog about Java. Παρασκευή, 21 Ιουνίου 2013. A few things about software design. While there are a number of frameworks for web development (JEE, Spring etc.) that provide Off-The-Shelf design guidelines to help developers structuring their code, standalone (desktop) applications lack one. It is unfortunate to see even very good developers having difficulties in designing their code and creating spaghetti code. Sub-package and inside there create the domain objects as Plain Old Java Objects (POJOs).
