Software Development
There are several operating systems to write programs for and numerous language to write in. And some of them I used before (see image above).
Operating systems (as well as browsers) partly dictate the programming language, but mostly you can choose between among several ones.
The most common decision is: Fast and cheap (also known as 'quick and dirty') or dig a little deeper and produce for reusability and security.
For both ways there may be valid reasons, but for me the second is the more appealing one.
Principles
The main goal of every software is obviously to serve its purpose. But beyond that I see some more common goals, which will improve every software:
Clarity
The software has to serve a clear obvious objective.
Simplicity and a clear structure get precedence over all-in-one frameworks.
The code has to readable like prose. In structure and naming it is orientatiated at real objects.
Simplicity
Usage has to be quick and simple, as intuitive as possible.
Simplicity of software usually also means swiftness and less expensive hardware. Not least, with simple software better security can be ensured more easily.
Security
From my experience in developing banking software this has become important to me: No vulnerable HTML, no vulnerable databases, as many scripts as needed, as much compiled code as possible.
