Out in the Edgeworth–Kuiper belt

NASA’s New Horizons spacecraft has been returning some exciting data, after a long flight through the solar system:

This documentary provides illuminating background on the mission: The Year of Pluto.

It is much to be hoped that the New Horizons craft will be able to observe other Kuiper belt objects.

Black Code

Written by Ron Diebert, the director of the Citizen Lab at U of T, Black Code: Inside the Battle for Cyberspace contains some very interesting information, of importance to anyone concerned with the future of the internet and communication. He discusses the major discoveries made by the lab, including massive criminal malware enterprises, government surveillance and censorship, and the use of cyberweapons like Stuxnet.

The first few chapters may seem basic if you actively follow the news on IT security and surveillance, but the material in the later parts is undeniably novel and interesting. The book is a bit of a lament for the death of the idealistic open internet, and the emergence of control by governments, particularly after the 2001 terrorist attacks in the United States.

The stakes here are high: the internet is a critical tool for maintaining democracy in open societies, confronting autocratic regimes, and dealing with global threats. The network is now in real danger of being suffocated by governments fixated on terrorism or maintaining domestic control, or who see it as a promising avenue for attacking their enemies.

Diebert proposes a distributed model for both securing and protecting the internet, while repeatedly underlining how governments are now the major threat to online freedom and political participation. Governments have rebuilt the backbone of the internet in order to achieve their censorship and surveillance objectives. It’s not a problem with a technical solution, from the perspective of citizens, but rather one which requires ongoing political agitation.

Consequences of nuclear weapon proliferation

The Economist draws attention to the risk of nuclear war:

New actors with more versatile weapons have turned nuclear doctrine into guesswork. Even during the cold war, despite all that game theory and brainpower, the Soviet Union and America frequently misread what the other was up to. India and Pakistan, with little experience and less contact, have virtually nothing to guide them in a crisis but mistrust and paranoia. If weapons proliferate in the Middle East, as Iran and then Saudi Arabia and possibly Egypt join Israel in the ranks of nuclear powers, each will have to manage a bewildering four-dimensional stand-off.

STS-27/107

I fear that my list of project ideas, which I assemble out of an optimistic hope that the future will bring a long span of free time for such undertakings, includes an idea for a screenplay.

It would be a film in the style of Apollo 13 (technically and historically accurate, and developed with lots of research in collaboration with the people involved) based on the STS-27 and STS-107 Space Shuttle missions.

I have a bunch of ideas, but I definitely don’t have time to write such a script, given my work with Toronto350.org, photography, and being on strike as a TA at U of T.

Still, I think it could be a powerful story. Ultimately, it’s a sadder story than Apollo 13, which may limit its aesthetic and commercial appeal. Still, like any story about crewed spaceflight, this is a story of courage and dedication applied in the pursuit of scientific understanding. Twelve amazing people: 5 who lived and 7 who died.

I can provide a more detailed breakdown of the screenplay idea, if someone wants to try working on it a bit.

The fall of Berlin, 1945, part 13/13

“The merciless shelling had no pattern. It was aimless and incessant. Each day it seemed to increase in intensity. Mortars and the grinding howl of rocket-firing Katashkas soon added to the din. Most people now spent much of their time in cellars, air raid shelters, flak tower bunkers and subway stations. They lost all sense of time. The days blurred amid the fear, confusion and death that was all about them. Berliners who had kept meticulous diaries up to April 21 suddenly got their dates mixed. Many wrote that the Russians were in the center of the city on April 21 or 22, when the Red Army was still fighting in the suburbs. Their terror of the Russians was often intensified by a certain guilty knowledge. Some Germans, at least, knew all about the way German troops had behaved on Soviet soil, and about the terrible and secret atrocities committed by the Third Reich in concentration camps. Over Berlin, as the Russians drew closer, hung a nightmarish fear unlike that experienced by any city since the razing of Carthage.”

“By now confusion was beginning to sweep the German lines. Shortages were apparent everywhere and in everything. A critical lack of transport, an almost total absence of fuel, and roads thronged with refugees made large-scale troop movements almost impossible. This immobility was producing dire consequences: as units shifted position, their equipment, including precious artillery, had to be abandoned. Communication networks, too, were faltering and in some places no longer existed. As a result, orders were often obsolete when they reached their destinations – or even when they were issued. The chaos was compounded as officers arriving at the front to take over units discovered nothing to take over, because their commands had already been captured or annihalated. In some areas, inexperienced men, left leaderless, did not know exactly where they were or who was fighting in their flanks. Even in veteran outfits, headquarters were forced to move with such frequency that often the troops did not know where their command post was or how to contact it.”

“In all, one third of Reymann’s men were unarmed. The remainder might as well have been. ‘Their weapons,’ he was to relate, ‘came from every country that Germany had fought with or against. Besides our own issues, there were Italian, Russian, French, Czechoslovakian, Belgian, Dutch, Norwegian and English guns.’ There were no less than fifteen different types of rifles and ten kinds of machine guns. Finding ammunition for this hodgepodge of arms was almost hopeless. Battalions equipped with Italian rifles were luckier than most: there was a maximum of twenty bullets apiece for them. Belgian guns, it was discovered, would accept a certain type of Czech bullet, but Belgian ammunition was useless with Czech rifles. There were few Greek arms, but for some reason there were vast quantities of Greek munitions. So desperate was the shortage that a way was found to re-machine Greek bullets so that they could be fired in Italian rifles. But such frantic improvisations hardly alleviated the overall problem. On this opening day of the Russian attack, the average ammunition supply for each Home Guardsman was about five rounds per rifle.”

“From Speer’s office Reymann made a quick visit to one of the defense sectors on Berlin’s outskirts. Each of these inspections only served to deepen Reymann’s conviction that Berlin’s defenses were an illusion. In the strutting, triumphant years, the Nazis had never considered the possibility that one day a last stand would be made in the capital. They had built fortifications everywhere else – the Gustav Line in Italy, the Atlantic Wall along the European coast, the Sigfried Line at Germany’s western borders – but not even a trench had been built around Berlin. Not even when the Russians drove with titanic force across eastern Europe and invaded the Fatherland did Hitler and his military advisors act to fortify the city.”
