In search of software perfection - 2016 Milner Award lecture by Dr Xavier Leroy.

source: The Royal Society     2016年11月28日
2016 Milner Award lecture by Dr Xavier Leroy, a senior research scientist at Inria where he leads the Gallium research team.
In the general public, "software" has become synonymous with "crashes" and "security holes". Yet, there exists life-critical software systems that achieve extraordinary levels of reliability. For example, fly-by-wire systems, involving considerable amounts of software, have been used in commercial airplanes for nearly 40 years without any incident caused by a software bug.
What does it take to achieve this kind of software perfection? This lecture will describe some of the approaches involved, with special emphasis on the use of formal verification tools - that is, programs that check other programs for the absence of whole classes of bugs. These tools provide highly valuable guarantees that complement, and sometimes subsume, the assurance obtained by more traditional techniques such as testing. Beware however: a bug in the verification tool or in the compiler that produce the actual executable from verified sources could ruin these guarantees. How can we rule out this risk? Using the CompCert verified C compiler as an example, the lecture will discuss a radical, mathematically-grounded answer: the formal verification, using proof assistants, of the tools that participate in the construction and verification of critical software.
The lecture was recorded on November 24 2016 at the Royal Society. For more events like this, see our schedule - http://ow.ly/KhTi306gTN1

Peter Duncan: How Putin reacts... - UCL Lunch Hour Lecture

source: UCL Lunch Hour Lectures     2016年11月22日
Speaker: Dr Peter Duncan, UCL School of Slavonic and East European Studies, Thursday 3rd November 2016, #ucllhl
Bring your lunch and your curiosity! UCL Lunch Hour Lectures, Tuesdays and Thursdays, Darwin Lecture Theatre, 1.15 - 1.55pm (term time)
How Putin reacts: ideology, power, wealth and security in Russian foreign policy
Dr Peter Duncan will argue that the deterioration of relations between Russia and NATO since Putin’s annexation of Crimea cannot be considered the prelude to a new Cold War between two global blocs. And, rather than pursuing world communism, Putin’s aims are to strengthen his power and protect the wealth of himself and his allies.
