Scrum vs Waterfall – two different approaches to software development

There are many software development methodologies (or system development methodologies – which in my personal opinion is even better term) in the field of software engineering. Debates on their pros and cons are countless, the same way like other discussions of such kind – for example: "which programming language is better"? The answer is simple – this methodology is better in given case, which suits the requirements and conditions best. The problem is – it is hard to choose the proper one. Therefore, to stay current with the latest trends, it is a good idea to watch the shortest (I've ever seen) introduction to Scrum – an iterative and incremental agile software development framework for managing product development – and compare it to the well-known Waterfall model.

Submarine cabling. The core of our global connectivity

Having in mind that more than 70% of Earth’s surface is covered with the oceans, we can ask a question – how we wired our planet to allow global connectivity? For most of the time we use Internet services – doesn’t matter where in the world, we assume there is a way to establish a connection (which is not exactly true, of course). Internet – for good – seems to be a part of our reality right now. In developed countries we cannot imagine proper living without the Internet services, the same way as we think about water availability or electricity. Honestly, the things are not so easy, even if we don’t see how much effort is required to provide all these goods worldwide. So, if we would like to see where the most important cables are placed, there is a good reference available on the web…
