If one big complex thread being executed too fast is risky as we saw, because there’s a physical limit to sheer clock speed and cheating optimisations are unsafe, then, we all know the other option: what about doing many simple and small things independently? To put it differently: if we cannot make the clock any […]

Processors, Part Two: the Present. Meltdown and Spectre
Imagine a restaurant. A professional chef, in charge of the best pizzas in town, and nobody knows how’re they done. It’s such a secret, those magic ingredients. And imagine a bunch of apprentices, supposed to help him. Imagine them following the chef’s orders. And then see, the chef going to the fridge to take some […]
The Von Neumann Architecture, a friend and a foe
Von Neumann, another star from Göttingen, gave the next important step in computation after Turing (checkout my previous post for Turing’s first step), in a way that, to this day, you can’t talk about computers without talking about Von Neumann. Which came first: the Hardware, or the Software and Languages? In an analogous way to […]
What has Turing given to us
Last time, I mentioned to have befriended Alan Turing. Who? You might fairly ask. Why? Those who already know him might add. Let me answer those questions. Three years ago (pretty accurately), Leon and I were passing by Göttingen. It was our first bike trip, and along the road, we agreed this city was a […]
How I befriended Alan Turing
While Leon has been learning about arts, and he as been writing about it, I caught up with a hobby of my own as well, but I have been silent about it. I befriended Alan Turing. And it’s time I talk about it. Let me keep it short so I can get to the point. Some […]
