You could argue – as some folks have – that mainframes are inherently more secure than commodity servers because there are fewer variables at play on mainframe systems, making them easier to secure in some ways. The fact that mainframes account for a relatively small...
What even is a mainframe anyway? If you asked me a few months ago what a mainframe was, I don’t think my reply would have gone much further than “a big computer”. Now, as I approach the final stages of my IBM Z Xplore journey, I’m fully convinced of the importance of...
High computing power and computing resources in a centralized architecture and distributed computing resources in the cloud are the two major variations that today’s IT businesses use. But concerning selecting one, should you choose between mainframe systems and cloud...
Mainframe systems are highly relevant even under the shadow of cloud computing. And, why not? Businesses need them to carry out millions of monetary or data transactions per minute to stay afloat. Mainly, people from Google Cloud, Microsoft Azure, AWS, and other...
Computer science can – and otherwise should – be interpreted as a continuation of philosophy by other means. Why? Computer science and its evolution into artificial intelligence are raising existential questions. Not just about technology but about human nature...
Federico Faggin, the inventor of the microchip, has been turning his gaze ever more toward and inside the human being. He has said in various interviews, in his native Italy, that his new goal, far more than improving computing capacity, is to teach people, regular...
In 2022, physicists Alain Aspect, John Clauser, and Anton Zeilinger (and posthumously John Bell, who came up with the concept in the 1960s) collect their Nobel Prize for physics thanks to their groundbreaking work on quantum entanglement as a clever scientific...
Quantum computing is the next frontier in the information revolution. Its potential appears both limitless and frightening: it is bringing science fiction into reality. To make sense of its implications for technology and society at large, it is worth analyzing...
2021 marked the 60th anniversary of the death of Mario Tchou, the Olivetti engineer who designed the Elea 9003, the first Italian computer, who died in a car crash at the age of only 36. However, the circumstances around his death, a car crash, remain suspicious....
The current computer infrastructure is based primarily on semiconductors. This class of electronic devices emerged around the mid-20th century and has seen capacity improvements at an almost exponential rate ever since. For decades, silicon has been the material used...
