Chickenhawk

Chickenhawk

Robert Mason

1983


A raw and largely uncensored account of the life of a "slick" (troop-carrying) helicopter pilot's life in Vietnam. It's a great mix of war story, flight training manual, memoir, and anti-war polemic, gradually shifting between these various facets as time goes on.

Mason doesn't glamorise the war or his own part in it; nor does he gloss over details that must have been uncomfortable to write (and for his family and friends to read). What comes through strongly is heroism on a small scale and pointlessness on a large scale: repeatedly and bravely storming the same pieces of territory as the "strategy" of attrition wears down both sides. In between are some wonderful flight scenes and descriptions of helicopter tactics that will fascinate any technically-inclined reader.

The epilogue covering his return from Vietnam is poignant and revealing of the challenges that many veterans faced as they tried (and often failed) to re-integrate themselves. It's an inconvenient truth that many societies -- and the UK is no better than the US in this -- fail to deal with their troops well once they're out of the field, no matter how much they applauded them while the war was on.

How computer science can help keep you healthy

Well, it has to be good for something...

People sometimes aren't aware just how much computers influence their lives. They've used the internet and mobile phones, seen computer-generated imagery in cinemas, and perhaps realised how much date is being sensed around them. But there are enormous applications for computers in science, arts, and medicine.

Earlier today I did an introductory lecture on using computers to study disease epidemics:

Com­pu­ta­tional epi­demi­ology is the use of math­em­at­ical and com­pu­ta­tional tech­niques to model how dis­eases spread. This is import­ant for answer­ing a num­ber of ques­tions. How infec­tious are dif­fer­ent dis­eases? Why are dif­fer­ent pop­u­la­tions affected dif­fer­ently? How do dif­fer­ent treat­ment regimes work? Is quar­ant­ine effect­ive? We can address these sorts of ques­tions using a range of dif­fer­ent tech­niques, ran­ging from dif­fer­en­tial equa­tions (cal­cu­lus) for simple cases through to com­plex net­works and high-performance sim­u­la­tion for com­plex case — and pos­sibly even mod­el­ling real dis­eases in real-world geo­graph­ies in real time.

This lec­ture is an inter­act­ive intro­duc­tion to these ideas. We’ll explore how dis­eases spread; con­duct an exper­i­ment where we infect each other (kind of); and then see how dif­fer­ent aspects of com­puter sci­ence help us to explore dis­eases and their treatment.

The slides and other material are available here. I've included the slides, and an animation of a simulated epidemic running through a population of people. I've also included an IPython notebook describing some of the mathematics needed and containing all the code I used to generate the graphs and animation from the talk, which might be handy for anyone wanting to explore this area more thoroughly.

1913: The World Before the Great War

1913: The World Before the Great War

Charles Emmerson

2013


A rounded tour of the horizons of the year before the Great War.

Emmerson structures his history around the great cities of the world: London, New York, Paris, St Petersburg, and Berlin, all obviously, but also Mexico City, Durban. Winnipeg, Melbourne, Detroit, and others. He uses them as nuclei around which to describe the core events and factors driving the populations. That they are universally unaware of the catastrophe that is bearing down on them only reinforces the strange nature of the Great War, that its origins seem to defy credible explanation.

It's impossible to read this book without being reminded of The Proud Tower : A Portrait of the World Before the War, 1890-1914, Barbara Tuchman's portrait of Europe in the same period. And if Emmerson lack something of Tuchman's elegance, it's only a matter of degree: he has the same eye for anecdote, the same beautiful turns of phrase. He also favours wider-ranging sociology over Tuchman's considerations of art and politics. IN many ways to two books make useful companion pieces.

The overriding impression for a modern reader is the almost universal acceptance of racist and sexist foundations for societies, extending both to the rulers and to the ruled. Gandhi fights for the rights of Indians in South Africa without concerning himself about the rights of Africans; Irish Nationalists struggle for independence but deplore votes for women. The ability to rationalise clearly hasn't changed over the years.

CfP: Spatial and Collective Awareness workshop at SASO'15

The first workshop on Spatial Awareness is being held in Boston in September as part of the SASO conference.

First International Workshop on Spatial and COllective PErvasive Computing Systems (SCOPES) Workshop

Co-located with IEEE SASO 2015, located at MIT, Cambridge, USA

September 21, 2015

http://www.spatial-computing.org/scopes

Overview

This workshop aims at combining three distinct, yet closely related areas of research, which will likely together play a major role in producing the key technical results needed to develop large-scale adaptive distributed systems of future networked scenarios.

  • Spatial computing: Spatial computing systems are systems of individual entities, typically situated in a physical environment, in which the “functional goals” of the system are generally defined in terms of the system's spatial structure. Typically, such systems are developed following a self-organisation approach, making spatial patterns arise by emergence.
  • Collective adaptive systems: Collective computing systems are systems of tightly entangled components, achieving an overall goal through widespread cooperation, typically relying on self-adaptation techniques and collective/social intelligence.
  • Pervasive computing: Pervasive computing systems and the “Internet of Things” deal with current and emerging scenarios in which humans, sensors, mobile, and embedded devices engage in complex interactions in a shared environment.

The goal of this workshop is to foster the creation of general-purpose solutions for supporting the development of these kinds of systems, particularly as regards generalizable techniques and architectures. Topics of interest include:

  • Foundational models of spatially embedded collective systems, exhibiting resilience, robustness and scalability properties as required by emerging pervasive computing scenarios.
  • Tools and tool-chains targeting large-scale situated systems: programming or specification languages, compilers and proof-checking techniques, simulators, tools for property verification, libraries and APIs, supporting platforms, whole infrastructures.
  • Innovative methods and techniques for system development, including design patterns, software methodologies, best practices, and practical experience reports.
  • Applications contexts and scenarios of general interest to foster the identification of new problems and solutions, taking inspiration from cyber-physical systems, the Internet of things, sensor networks, smart-cities, etc.

Paper submission

Papers should present original work and be no longer than 6 pages in the standard IEEE two-column format. All manuscripts should be submitted in PDF form through the submissions system for SCOPES at EasyChair. Papers will be peer reviewed on the basis of originality, readability, relevance to themes, soundness, and overall quality. Workshop proceedings will be published on IEEE Xplore in parallel with the main conference proceedings. Post-proceedings publication in a journal is planned. Questions should be addressed to saso.scopes2015@easychair.org.

Death in Florence: The Medici, Savonarola and the Battle for the Soul of Man

Death in Florence: The Medici, Savonarola and the Battle for the Soul of Man

Paul Strathern

2011


A well-paced and diverse account of a critical piece of European political and intellectual history.

The subject of the book is the clash of ideas between modernism and fundamentalism, as respectively represented by Lorenzo de' Medici and Girolamo Savonarola. Florence and Italy more widely provide a stage set with a range of characters, both those intent on their own betterment and those devoted to higher causes. The book manages to navigate a path between the ideas in play and the sometimes squalid and violent means with which these ends were pursued.

There are enormous ironies in these ends, too. Savonarola was a fundamentalist who wanted to introduce more democratic forms, and which gave rise to many modern ideas of governance – but abhorred the freedoms that such democratic ideas brought with them. Lorenzo kept tight political control but allowed great freedoms to the citizens, whilst being unable to distinguish between what was good for Florence and what was good for the Medici – and recalled Savonarola to Florence to be both a moral force and an ornament to the city's greatness, laying the foundations for the end of Medici rule.

As in his other book on Mediaeval Italy, The Artist, the Philosopher, and the Warrior: The Intersecting Lives of Da Vinci, Machiavelli, and Borgia and the World They Shaped, Strathern shows an well-balanced sense of character and an ability to juggle a range of sources of variable trustworthiness. He also has a keen eye for anecdotes: my two favourites are the shock that the arrival of French armies trained in full-on Northern European warfare caused for Italian armies used to a far more civilised form of warfare in which few people er actually got killed; and how the phrase esperimento del fuoco (trial by fire) gave rise to the word "experiment", a trial to which some facet of the world was subjected. He deftly manages the difficult task of making clear the bewildering changes of political alliances that were characteristic of Italian politics of the period. And he sets the clash of ideas into the broader context of the Renaissance, the Reformation, and both Luther's debt to Savonarola and the fact that Savonarola would have hated all Luther stood for: another paradox in a complex man.

It's easy to see the parallels with the modern world and the struggle between democracy and fundamentalist religion, but Strathern is too goo a historian to avoid the complexities that history beings to this comparison. Savonarola the fundamentalist was also Savonarola the democrat; Lorenzo the autocrat was also a committed and in many ways conservative religious figure. The modern concepts and dualities don't translate back to the fifteenth century, much as many might like them to, and this book is an important guide to the ways in which ideas mutate over time.
