This document contains an introduction and 8 chapters about securing Drupal websites against vulnerabilities. It discusses common vulnerabilities like SQL injection, cross-site scripting, and cross-site request forgery. It provides guidance on secure configuration, access controls, input sanitization, theme development, and automated security testing. Later chapters explore finding and avoiding vulnerabilities in the wild and techniques for "un-cracking" Drupal sites.
Automated, Non-Stop MySQL Operations and Failover discusses automating master failover in MySQL to minimize downtime. The goal is to have no single point of failure by automatically promoting a slave as the new master when the master goes down. This is challenging due to asynchronous replication and the possibility that not all slaves have received the same binary log events from the crashed master. Differential relay log events must be identified and applied to bring all slaves to an eventually consistent state.
10 Insightful Quotes On Designing A Better Customer ExperienceYuan Wang
In an ever-changing landscape of one digital disruption after another, companies and organisations are looking for new ways to understand their target markets and engage them better. Increasingly they invest in user experience (UX) and customer experience design (CX) capabilities by working with a specialist UX agency or developing their own UX lab. Some UX practitioners are touting leaner and faster ways of developing customer-centric products and services, via methodologies such as guerilla research, rapid prototyping and Agile UX. Others seek innovation and fulfilment by spending more time in research, being more inclusive, and designing for social goods.
Experience is more than just an interface. It is a relationship, as well as a series of touch points between your brand and your customer. Here are our top 10 highlights and takeaways from the recent UX Australia conference to help you transform your customer experience design.

However, personalization can create issues for search engine optimization as dynamic URLs and content are more difficult for search engines to index than static pages. The document provides tips for SEOs to help address these personalization and SEO challenges, such as using static URLs when possible and submitting accurate sitemaps.
The document describes the requirements for an embedded software program that will control a thermostat. The program is required to measure and display the temperature, keep time on a clock, accept time settings to define heating and cooling periods, compare the temperature to the set points for the current period and turn external heating and cooling units on and off as needed. It also needs to accept manual overrides and not change the state of external units too frequently to allow them to operate properly. The hardware requirements include a built-in debug interface to allow for customization and repairs on site.
