Cloud ... International Scholarships Jobs week ending 11 March 2018

Most developers spend about 60% of their time building and the rest of their time learning. Often the research is proactive, due to personal interest or a desire to ensure skills are up to date. I am in this camp. At other times it is borne of sheer necessity. You learn what is vital to tackling your next big project. I am also in this camp (no one says you have to choose). In the past new projects assumed a hosted or on premise approach. The project manager and system designer had to think about the essential requirements like scalability, availability and (of course) security. In the present we still need to deliver on these essentials but the app developers now need to do a lot more (as always). They need to span the globe, support millions of users, curate petabytes of data, glean insights and delight users in new ways.

And then to quote Adam Richardson, every tech product became white, silver, gray, black, flat, square, round and minimalist. Did you think boring? He also posits that in the past 2 or 3 decades the German branch of industrial design has dominated. This approach is characterized by clean geometric shapes (cubes, cylinders), white and black glossy colours, and smooth unadorned surfaces.

DX ... International Jobs and Scholarships week ending 10 December 2017

If you do not already know, here is a newsflash:we are firmly in December. #lastlap. In the Defence Academy it was always said that, “It is not over until it is over. Wake up there!”. This simply means that you should keep up the pace until you cross the finish line and if necessary for some time after that. If you snooze you lose. The ending is everything. We can go on and on. Besides the military folk, software developers, medical professionals, journalists, and students quite a few people end the year with a flurry of activity. Some Premier League teams will have to squeeze up to 7 competitive matches in the next 4 weeks and the enablers of online retailers such as Amazon’s ‘fulfilment’ associates are expectedly pedal to the metal. #bringingthebacon. Digital Transformation (DX) is not on the horizon. Like Game of Thrones season 7, it (winter) is here. DX is happening now and organisations are taking notice therefore we ought to take notes.
The strategy for DX will differ from busine…
