More Digital Art from Generative Adversarial Networks  First, the "Unreal Engine" Version Then, the "Watercolour" Version

  My first attempt at original, digital art using the magic of Generative Adversarial Networks. Using the Colab notebook built by Hillel Wayne.

Whether it is really true or not, Twitter has often been accused, often in anecdotal terms, as being biased towards the “Left-Liberal” edge of the political spectrum. This point of view got a boost when Elon Musk launched a hostile take-over bid of the company under the banner of free-speech and a whole bunch of self declared Left-Libs claimed that they would leave Twitter and move to Instagram if and when Elon Musk takes over. Now that the Board of Twitter has capitulated and accepted Musk’s offer, it is time to explore how this issue of censorship and free-speech will be addressed. Musk has of course tweeted that even his most severe critics will be allowed on the platform but opinion is divided on his real commitment. Will he be fair? The answer to that question lies in the womb of futurity but in the meanwhile, let us explore an alternative approach to ensure free speech. We are looking for something that eliminates or reduces the discretionary power of human beings, the so-called ...

 Introduction Astrology is based on the analysis and detection of correlated patterns. Causation and correlation are two different ways of studying related phenomena. Switching on an oven is the obvious cause for a cake to be baked but the consumption of flour, sugar, eggs, butter and electricity in the kitchen is strongly correlated to the appearance of a cake. These six events are part of a pattern and the presence of the first five will be correlated to or lead to a prediction of the presence of the sixth.  Viewed from this perspective of pure correlation, astrology is no different from data science where a pattern of data - in this case the positions of planets at birth – is used to calculate the possibility of certain outcomes. The astronomical observations that were made with the naked eye and recorded in a vast database by Tycho Brahe and his sister Sophia were the basis for the formulation of Kepler's Laws of Planetary motion, that in turn led to Newton's laws of gravi...

 

Five Drivers of the emerging civilisation It is always fascinating to speculate on the contours of the future, but perhaps it is easier to do so in terms of what might actually shape it. Rather than trying to define where we want to go or determine how to go there, let us instead try to determine who, or what, our drivers are and let them lead us into whatever it is that awaits us in the years, and the road ahead. So sit back and take a ride through a  thoughtscape  delineated by nuclear energy, space travel, biohacks, the metaverse and artificial intelligence. A ride that ends with an unusual Indic twist in the tail or tale. Energy The first driver is energy which is what gives dynamism to an otherwise static universe. It is obviously a prime driver for the emergence of civilisation, which is why the discovery – and control – of fire was such an epochal event in the evolution of human society. Without access to substantial sources of energy, human society can only regress to...

 Celebrated Engineers Day by reaffirming my identity as a Mechanical Engineer and building this Mars Buggy with a kit from Ukraine Gears . Cost me about 4 hours of work and a very sore thumb. Wish I had a tool to press in the wooden pieces

We are surely aware of SaaS or Software as a Service but let us explore the intriguing concept of the Crisis as a Catalyst for Change. Y2K - 1999 Those of us who are old enough to have been professionally active during the Y2K era, would recollect that industrialised societies, especially the US, were in a tizzy over how computer systems, both private and public, would collapse on 31 Dec 1999. This was because of the way dates had been defined with two digit years since the dawn of the computer age in the early 1960s and no one had thought that 99 would be followed by 00. Hence massive IT projects were commissioned to make systems Y2K proof by rewriting the code to accommodate four digit years so that 1999 would be followed by 2000. But the size of the task -- spanning so many organisations and their plethora of systems -- was so huge that there were simply not enough programmers to make even this simple change. At this point of time, software companies in India were trying to do busin...

Software artifacts that display artificial intelligence are increasing in both number and sophistication. There are many definitions of what constitutes intelligence and there are many ways in which software has been programmed to demonstrate the same. Of all the many options,  the use of artificial neural networks (ANN), that closely mimic the connectionist approach of animal brains, has been found to be most effective in performing tasks that are both useful and insightful. This includes, for example, recognising faces, driving cars, generating meaningful text passages and playing a wide range of games both against humans and against other programs. It may not be the case that the ANN will always be the best way to demonstrate this kind of intelligent behaviour, so for the purpose of this study an ANN is neither necessary nor sufficient. All that we need is a digital artifact -- a container of data, code, model, APIs or a combination of some of these -- that we will refer to as a...
