The urge to create more and more indexes is found to be causing severe damage in many systems. Many times, removing indexes is what we should be doing first before considering any new indexes for the benefit of the entire system. This post is about PostgreSQL, but most of the problems also apply to other database systems.

However, with today’s highly connected digital world, monitoring use cases expand to the services, processes, hosts, logs, networks, and of course end-users that access these applications – including your customers and employees. Websites, mobile apps, and business applications are typical use cases for monitoring.

Without data backup mechanisms, there can be data loss or system downtime. Even worse, entire operating systems can crash, also resulting in data loss. Choosing the right backup frequency: The appropriate frequency, of course, will vary from one organization to another. Similarly, accidental deletion is a culprit.

To many designers and developers the process of designing for mobile assumes that touch is natural, so we don’t need to pay any particular attention to the design of touch systems. Feature phones all use proprietary and little known operating systems developed by the makers of the phones, as opposed to prevalent ones like Android or iOS.

Challenging this idea, and suggesting that in complex systems, this linearity is soothingly deceptive?—?but In fact, non-determinism itself is considered a bug: if the unexpected or errant output isn’t reproducible, then developers tend to extend their investigation into other parts of the stack (operating system, network, etc.)
