Right now, there about 1,100 satellites whizzing above our heads performing various functions like observation, communication, and spying. There are roughly another 2,600 doing nothing, as they died or were turned off a long time ago.
How did each of these satellites get up there? And what nations are responsible for sending up the bulk of them?
The answers come in the form of this bewitching visualization of satellite launches from 1957 – the year Russia debuted Sputnik 1 – to the present day. (The animation starts at 2:10; be sure to watch in HD.) Launch sites pop up as yellow circles as the years roll by, sending rockets, represented as individual lines, flying into space with one or more satellites aboard.

This book explores the relationship between living, code and software. Technologies of code and software increasingly make up an important part of our urban environment. Indeed, their reach stretches to even quite remote areas of the world. Life in Code and Software introduces and explores the way in which code and software are becoming the conditions of possibility for human living, crucially forming a computational ecology, made up of disparate software ecologies, that we inhabit. As such we need to take account of this new computational environment and think about how today we live in a highly mediated, code-based world. That is, we live in a world where computational concepts and ideas are foundational, or ontological, which I call computationality, and within which, code and software become the paradigmatic forms of knowing and doing. Such that other candidates for this role, such as: air, the economy, evolution, the environment, satellites, etc., are understood and explained through computational concepts and categories.
Introduction: What is Code and Software?

Hidden in the landscape of the fertile crescent of the Middle East, scientists say, lurk overlooked networks of small settlements that hold vital clues to ancient civilizations.
Beyond the impressive mounds of earth, known as tells in Arabic, that mark lost cities, researchers have found a way to give archaeologists a broader perspective of the ancient landscape. By combining spy-satellite photos obtained in the 1960s with modern multispectral images and digital maps of Earth’s surface, the researchers have created a new method for mapping large-scale patterns of human settlement. The approach, used to map some 14,000 settlement sites spanning eight millennia in 23,000 square kilometres of northeastern Syria, is published today in the Proceedings of the National Academy of Sciences.
“Traditional archaeology goes straight to the biggest features — the palaces or cities — but we tend to ignore the settlements at the other end of the social spectrum,” says Jason Ur, an archaeologist at Harvard University in Cambridge, Massachusetts, who is co-author of the study. “The people who migrated to cities came from somewhere; we have to put these people back on the map.”
Such comprehensive maps promise to uncover long-term trends in urban activity. “This kind of innovative large-scale application is what remote sensing has been promising archaeology for some years now; it will certainly help us to focus our attention on the big picture,” says Graham Philip, an archaeologist at Durham University, UK.
