In this episode we talk with Brano Kemen about his Outerra project, a 3D planetary engine for seamless planet rendering from space down to the surface.. We discuss the history of the project, its most interesting features, some of the physics, as well as some details about the rendering in the system. I highly recommend taking a look at the Outerra Youtube Channel, specifically the Himalaya Trip and the Apache flight.

This episode covers Bitcoin, a digital, decentralized currency. In our conversation with Gavin Andresen, the technical lead of the project, we cover basic economics of money, the way users interact with Bitcoin, as well as the technical implementation of the system. Bitcoin uses a couple of clever ideas about implementing distributed clocks and global ordering, and is a very nice example of applied cryptography.

Diese Episode ist ein Gepräch mit Henning Butz, langjähriger (leitender) Mitarbeiter bei Airbus und derzeit freier Berater für Systems Engineering (ASES – Advanced Systems Engineering Solutions). Wir reden über komplexe Systeme, Fehlersymptome sowie deren Beherrschung, insbesondere auch im Zusammenspiel mit dem Menschen. Zunächst definieren wir die Begriffe System und Komplexität und klassifizieren verschiedene Arten des Fehlverhaltens. Wir illustrieren diese mit Beispielen aus der Luftfahrt, Raumfahrt und anderer sicherheitskritischer Systeme. Im nächsten Schritt betrachten wir, wie komplexe Systeme so gestaltet werden können, dass sie sinnvoll mit einem Menschen zusammenspielen. Im letzten Teil betrachten wir die Entwicklung komplexer Systeme, insbesondere die Methode des Component/Contract-Based Design.

In this Episode, we talk about quantum computing. Our guest is Martin Laforest from the Institute for Quantum Computing at the University of Waterloo, Canada. We start with some physics basics, and then cover topics ranging from how quantum computing works, which different models of quantum computing are explored, current and future uses of the approach as well as the current state of the art. This is one of the more propellerhead-oriented episodes, so make sure you listen carefully :-)

In this episode we take a look at microchip production, with a special focus on waferscanners. To do this, we talked with Wilbert Albers of ASML, the leading waferscanner manufacturer in the world. In the episode, we talk about the overall chip production process (from silicon sand over wafer cutting to lithography and etching), and then we talk about the challenges of building high-precision, high-throughput waferscanners.
