I spent a whole day trying to figure out a Struts validator problem. It's a web application containing three modules, but only one module does not perform Struts validation. The XML config files are perfectly fine, but no clue was given by the logger or compiler. The log file spits validateInteger error, but no helpful hints whatsoever were given even after turning on the root level logging to DEBUG level.

Previsor PHP assessment test

Mar 11, 2010 By Web Traffic Exchange Development 0 Last Modified on 2024-01-16

With more and more companies using pre-employment screening tests such as the one provided by Previsor, LAMP developers and PHP developers should hone their technical skills to prepare for their next career. Having taken one, the Previsor assessment test resembles College Board Tests such as the ACT and SAT, which tests students' general understanding of the subject (in this case "PHP"). PHP, especially version 5, is a great scripting language for developing web applications very rapidly with minimum effort. Since PHP is not really a university-level programming language, most of us familiar with the language picked up its grammar, syntax, and OOP'ness on our own whether experimental or work-related. Having to take the assessment test allows PHP developers to review the language semantics and grammar in a more academic fashion. However, judging a programmer's ability solely based on the assessment test score is "probably" not appropriate as most software engineers work with more than one programming language, and the time spent on one language may not correctly represent one's software engineering ability.

Have you ever pushed your limit on SEO efforts, and experienced the OOP? On November 15, 2003, the Google SERPs were dramatically altered by Hurricane Florida, also known as the Over Optimization Penalty.
